DESCRIPTION OF EMBODIMENTS
The solutions in the embodiments of the present disclosure are hereinafter described in detail and completely, with reference to accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part, but not all, of the embodiments of the present disclosure. All of the other embodiments that are obtained by those skilled in the art based on the embodiments in the disclosure without any inventive efforts fall into the scope protected by the present disclosure.
Embodiment 1
An embodiment of the present disclosure provides a method for UE to report a measurement result. As shown in FIG. 1, the embodiment of the present disclosure specifically includes:
S101, determining a moving speed state of the UE, and determining a measurement parameter according to the moving speed state.
The UE may determine the moving speed state of the UE according to the number of switched or residing cells within a period. For example, the UE may acquire its own moving speed state according to the number of switched cells within a period. When the UE moves in an urban environment, coverage of a cell is relatively small, and distribution of base stations is relatively dense. If the number of the switched cells of the UE every 10 minutes is not less than 5, the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is not less than 3, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is less than 3, the moving speed state of the UE is considered as a normal moving speed state. When the UE moves in a suburban environment, coverage of a cell is relatively large, and distribution of base stations is relatively sparse. If the number of the switched cells of the UE every 10 minutes is 2, the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is 1, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is not more than 1, the moving speed state of the UE is a normal moving speed state.
Certainly, the UE may determine its own moving speed state by adopting other methods, and then define a specific high moving speed state, medium moving speed state and normal moving speed state by adopting the corresponding method, which is not specifically limited in the present disclosure.
Correspondingly, if the moving speed state is the high moving speed state, the determined measurement parameter is a high moving speed state measurement parameter; if the moving speed state is the medium moving speed state, the determined measurement parameter is a medium moving speed state measurement parameter; and if the moving speed state is the normal moving speed state, the determined measurement parameter is a normal moving speed state measurement parameter.
The measurement parameter may be determined from a measurement parameter set sent by a base station according to the moving speed state of the UE; or be determined from a pre-configured measurement parameter set in the UE according to the moving speed state of the UE, and the measurement parameter set includes measurement parameters of different moving speed states.
S102, acquiring a measurement period of the UE according to the determined measurement parameter.
Wherein, different moving speeds correspond to different measurement parameter values. The measurement parameter specifically may be a time parameter or a parameter related to speed. Then the measurement period of the UE is acquired according to the time parameter or the parameter related to the speed determined by the moving speed state of the UE.
S103, measuring a cell to obtain a measurement result in the measurement period and reporting the measurement result to a serving base station of the UE.
In the measurement period, the UE measures the cell to obtain the measurement result, and then reports the measurement result to the base station, so that the base station determines whether the UE needs to perform cell switching and which cell the UE needs to be switched to according to the contents of the measurement result.
Certainly, when the UE measures the cell, the UE may measure a serving cell of the UE or simultaneously measure a serving cell and a neighboring cell of the UE.
Wherein, a measurement of the cell performed by the UE includes an intra-frequency measurement, an inter-frequency measurement and an inter-system measurement.
An embodiment of the present disclosure also provides a UE, As shown in FIG. 2, the UE includes: a determining unit 21, an acquiring unit 22 and a processing unit 23.
The determining unit 21 is configured to determine a moving speed state of the UE and to determine a measurement parameter according to the moving speed state.
The determining unit 21 of the UE may determine the moving speed state of the UE according to the number of switched or residing cells within a period. For example, the determining unit 21 may acquire its own moving speed state according to the number of switched cells within a period. When the UE moves in an urban environment, coverage of a cell is relatively small, and distribution of base stations is relatively dense. If the number of the switched cells of the UE every 10 minutes is not less than 5, the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is not less than 3, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is less than 3, the moving speed state of the UE is a normal moving speed state. When the UE moves in a suburban environment, coverage of a cell is relatively large, and distribution of base stations is relatively sparse. If the number of the switched cells of the UE every 10 minutes is 2, the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is 1, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is not more than 1, the moving speed state of the UE is a normal moving speed state.
Certainly, the determining unit 21 of the UE may determine its own moving speed state by adopting other methods and then define a specific high moving speed state, medium moving speed state and normal moving speed state by adopting the corresponding method, which is not specifically limited in the present disclosure.
Correspondingly, if the moving speed state is the high moving speed state, the measurement parameter determined by the determining unit 21 of the UE is a high moving speed state measurement parameter; if the moving speed state is the medium moving speed state, the measurement parameter determined by the determining unit 21 of the UE is a medium moving speed state measurement parameter; and if the moving speed state is the normal moving speed state, the measurement parameter determined by the determining unit 21 of the UE is a normal moving speed state measurement parameter.
Wherein, different moving speeds correspond to different measurement parameter values. The measurement parameters specifically may be a time parameter or a parameter related to speed.
The determining unit 21 may determine the measurement parameter from a measurement parameter set sent by a base station according to the moving speed state of the UE, or from a pre-configured measurement parameter set in the UE according to the moving speed state of the UE, and the measurement parameter set includes measurement parameters of different moving speed states.
The acquiring unit 22 is configured to acquire a measurement period of the UE according to the measurement parameter determined by the determining unit 21.
The processing unit 23 is configured to measure a cell to obtain a measurement result in the measurement period of the UE acquired by the acquiring unit 22 and to report the measurement result to a serving base station of the UE.
In the measurement period, the processing unit 23 of the UE measures the cell to obtain the measurement result, and then a physical layer of the UE reports the measurement result to a high-level RRC layer of the UE. The high-level RRC layer of the UE accurately and timely reports a measurement result satisfying a report criterion to the base station, so that the base station determines whether the UE needs to perform cell switching and which cell the UE needs to be switched to according to the contents of the measurement result.
Certainly, when the UE measures the cell, the UE may measure a serving cell of the UE or simultaneously measure a serving cell and a neighboring cell of the UE.
Embodiments of the present disclosure provide a method and a user equipment for UE to report a measurement result. The UE acquires the measurement parameters corresponding to different moving speed states. According to a judgment of a moving speed state of a UE, the UE acquires the measurement period of the UE. Then the physical layer of the UE reports the measurement result to the high-level RRC layer of the UE in the reported measurement period. The high-level RRC layer of the UE accurately and timely reports the measurement result satisfying a report criterion, to the base station. In this way, the measurement period of the UE is acquired according to the measurement parameter corresponding to the moving speed state of the UE. Therefore the measurement result may be timely, accurately reported to the base station when the UE is in the high moving speed state, so that communication continuity of the UE is improved.
Embodiment 2
An embodiment of the present disclosure provides a method for UE to report a measurement result. The method below is described by taking a UE of an LTE system as an example, wherein the measurement parameter is specifically a period parameter. Specifically, as shown in FIG. 3, the method includes:
S301, determining a moving speed state of the UE, and determining a period parameter according to the moving speed state.
The UE may determine the moving speed state of the UE according to the number of switched or residing cells within a period. For example, the UE may acquire its own moving speed state according to the number of switched cells within a period. When the UE moves in an urban environment, coverage of a cell is relatively small, and distribution of base stations is relatively dense. If the number of the switched cells of the UE every 10 minutes is not less than 5, and the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is not less than 3, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is less than 3, the moving speed state of the UE is considered as a normal moving speed state. When the UE moves in a suburban environment, coverage of a cell is relatively large, and distribution of base stations is relatively sparse. If the number of switched cells of the UE every 10 minutes is 2, and the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is 1, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is not more than 1, the moving speed state of the UE is a normal moving speed state.
Certainly, the UE may determine its own moving speed state by adopting other methods, and then define a specific high moving speed state, medium moving speed state and normal moving speed state by adopting the corresponding method, which is not specifically limited in the present disclosure.
Correspondingly, if the moving speed state is the high moving speed state, the determined measurement parameter is a high moving speed state measurement parameter; if the moving speed state is the medium moving speed state, the determined measurement parameter is a medium moving speed state measurement parameter; and if the moving speed state is the normal moving speed state, the determined measurement parameter is a normal moving speed state measurement parameter.
In this embodiment, the UE may merely determine that the moving speed state of the UE is the high moving speed state or the normal moving speed state, and certainly the UE may also determine the high moving speed state, the medium moving speed state and the normal moving speed state.
Wherein, the period parameter may be configured by a base station and then sent to the UE through a dedicated signaling and/or a system broadcast message, and certainly the period parameter may also be pre-configured in the UE. A specific process includes: the UE receives a period parameter set sent from the base station or a period parameter set is pre-configured in the UE, wherein the period parameter set includes period parameters of different moving speed states; and then the UE determines the period parameter from the period parameter set according to the moving speed state of the UE.
S302, determining a calculation parameter according to the determined period parameter.
Specifically, the period parameter determined according to the moving speed state is determined as the calculation parameter.
Or, the lower value of the period parameter and a pre-configured DRX cycle of the UE is acquired, and the lower value is determined as the calculation parameter.
According to the moving speed state of the UE, the period parameter may be a high moving speed state period parameter, a medium moving speed state period parameter or a normal moving speed state period parameter.
S303, determining whether the calculation parameter is greater than a preset period parameter threshold of the UE.
Period parameter threshold of intra-frequency, inter-frequency and inter-system are configured in the UE respectively, and the UE needs to determine the magnitudes of the calculation parameter and the period parameter thresholds corresponding to the intra-frequency, the inter-frequency and the inter-system respectively to determine respective measurement periods.
If the calculation parameter is greater than the period parameter threshold, S304 is executed; and if the calculation parameter is not greater than the period parameter threshold, S305 is executed.
S304, acquiring a measurement period of the UE according to the calculation parameter.
Wherein, a measurement of the cell performed by the UE includes an intra-frequency measurement, an inter-frequency measurement and an inter-system measurement.
For acquiring an intra-frequency measurement period, specifically, a threshold of an intra-frequency measurement period parameter may be pre-configured as 0.04 s. If the calculation parameter is greater than the threshold of the intra-frequency measurement period parameter, the intra-frequency measurement period of the UE is the product of a first natural number N1 and the calculation parameter, wherein the N1 is a preset natural number sent from a base station to the UE according to the high moving speed state through a dedicated signaling and/or a system broadcast message, and certainly the N1 may also be pre-configured in the UE, specifically as shown in table 1.

For an inter-frequency measurement period, specifically, a threshold of an inter-frequency measurement period parameter may be pre-configured as 0.08 s. If the calculation parameter is greater than the threshold of the inter-frequency measurement period parameter, the inter-frequency cell measurement period of the UE is the product of a second natural number N2, the number of inter-frequency layers Nfreq and the calculation parameter, wherein the N2 is a natural number preset by the base station according to different moving speed states and then sent to the UE through a dedicated signaling and/or a system broadcast message, and certainly the N2 may also be pre-configured in the UE; and the Nfreq is the number of the inter-frequency layers which need to be measured and are acquired by the UE through a system broadcast message and/or a dedicated signaling received from the base station, and the number of the inter-frequency layers Nfreq is the sum of the number of the frequency layers of the inter-frequency of the common-system and the number of the inter-system frequency layers of the UE. For this embodiment, the number of the inter-frequency layers indicates the sum of the number of the frequency layers of the inter-frequency of the LTE system and the number of the frequency layers of the non-LTE system, specifically as shown in table 2.

For an inter-system measurement period, specifically, a threshold of the inter-system measurement period may be pre-configured as 0.128 s. If the calculation parameter is greater than the threshold of the inter-system measurement period, the inter-system measurement period of the UE is the product of a third natural number N3, the number of inter-frequency layers Nfreq and the calculation parameter, wherein the N3 is a natural number preset by the base station according to different moving speed states and then sent to the UE through a dedicated signaling and/or a system broadcast message, and certainly the N3 may also be pre-configured in the UE; and the Nfreq is the number of the inter-frequency layers which need to be measured and are acquired by the UE through a system broadcast message and/or a dedicated signaling received from the base station. The number of the inter-frequency layers Nfreq is the sum of the number of the frequency layers of the inter-frequency of the common-system and the number of the inter-system frequency layers of the UE. For this embodiment, the inter-frequency layers may indicate the sum of the number of the frequency layers of the inter-frequency of the LTE system and the number of the frequency layers of the non-LTE system. For the UE using the LTE system, when an interval that the UE receives inter-system information, which is configured by the base station, is 40 ms or 80 ms, the measurement period of the inter-system corresponding to different calculation parameters corresponds to different values.

S305, determining a preset minimal measurement period of the UE as the measurement period of the UE.
Correspondingly, as mentioned in table 1, table 2 and table 3, if the calculation parameter is not greater than the threshold of the intra-frequency measurement period, the intra-frequency measurement period is the preset intra-frequencyintra-frequency minimal measurement period of the system, and specifically may be 200 ms; the inter-frequency cell measurement period is the preset inter-frequency minimal measurement period of the system, and specifically may be the product of 0.48 and the number of the inter-frequency layers Nfreq or the product of 0.24 and the number of the inter-frequency layers Nfreq; and the inter-system measurement period is determined according to the preset value of the system, for example, when the calculation parameter is not more than 0.04, if the measurement interval is not needed, the inter-system measurement period is 0.48 s, if the measurement interval is needed, the inter-system measurement period is the minimal measurement period of the inter-system. Specifically, for example, when a UTRAN (UMTS Terrestrial Radio Access Network, UMTS terrestrial radio access network) frequency point is measured and the measurement interval is not needed, the inter-system measurement period is 0.48 s; when the measurement interval is used, the inter-system measurement period is

S306, measuring a cell to obtain a measurement result in the measurement period and reporting the measurement result to a serving base station of the UE.
According to the acquired intra-frequency measurement period, inter-frequency measurement period and inter-system measurement period, in the corresponding measurement period, respectively, the UE measures the cell to obtain the measurement result and reports the corresponding measurement result to an RRC layer of the UE, and the RRC layer of the UE accurately and timely reports a measurement result satisfying a report criterion, to the base station.
Certainly, when the UE measures the cell, the UE may measure a serving cell of the UE or simultaneously measure a serving cell and a neighboring cell of the UE.
The LTE system is taken as an example for illustration in this embodiment. Certainly, this method is also applicable for other communication systems, such as TDSCDM, CDMA and the like. However, the specific period parameter thresholds and DRX cycles are configured to be different for different communication systems. The specific process will not be repeated redundantly herein.
According to the method for UE to report a measurement result provided in the embodiment of the present disclosure, the period parameter corresponding to the moving speed state of the UE is preset, and the measurement period of the UE is acquired according to the period parameter, so that the measurement result may be timely and accurately reported when the UE is in the high speed state, and the communication continuity of the UE is improved.
Embodiment 3
An embodiment of the present disclosure provides a method for UE to report a measurement result. The method below is described by taking a UE of an LTE system as an example, wherein the measurement parameter is specifically a speed parameter. Specifically, as shown in FIG. 4, the method includes:
S401, determining a moving speed state of the UE, and determining a speed parameter according to the moving speed state.
The UE may determine the moving speed state of the UE according to the number of switched or residing cells within a period. For example, the UE may acquire its own moving speed state according to the number of switched cells within a period. When the UE moves in an urban environment, coverage of a cell is relatively small, and distribution of base stations is relatively dense. If the number of the switched cells of the UE every 10 minutes is not less than 5, the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is not less than 3, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is less than 3, the moving speed state of the UE is considered as a normal moving speed state. When the UE moves in a suburban environment, coverage of a cell is relatively large, and distribution of base stations is relatively sparse. If the number of switched cells of the UE every 10 minutes is 2, and the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is 1, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is not more than 1, the moving speed state of the UE is a normal moving speed state.
Certainly, the UE may determine its own moving speed state by adopting other methods, and then define a specific high moving speed state, medium moving speed state and normal moving speed state by adopting the corresponding method, which is not specifically limited in the present disclosure.
Correspondingly, if the moving speed state is the high moving speed state, the determined speed parameter is a high moving speed state speed parameter; if the moving speed state is the medium moving speed state, the determined speed parameter is a medium moving speed state speed parameter; and if the moving speed state is the normal moving speed state, the determined speed parameter is a normal moving speed state speed parameter.
Wherein, the speed parameter may be configured by a base station and then sent to the UE through a dedicated signaling and/or a system broadcast message, and certainly the period parameter may also be pre-configured in the UE. The specific process includes: the UE receives a speed parameter set sent from the base station or a speed parameter set is pre-configured in the UE, wherein the speed parameter set includes speed parameters of different moving speed states; and then the UE determines the speed parameter from the speed parameter set according to the moving speed state of the UE.
S402, acquiring a measurement period corresponding to a DRX cycle according to a pre-configured DRX cycle of the UE.
For measurements of intra-frequency, inter-frequency and inter-system, the measurement period corresponding to the DRX is acquired respectively according to the pre-configured DRX cycle of the UE. The step of acquiring the measurement period according to the DRX belongs to the prior art, which will not be repeatedly redundantly herein.
S403, taking the product of the measurement period corresponding to the DRX cycle and the speed parameter as a measurement period of the UE.
The product of the measurement period corresponding to the DRX cycle of the intra-frequency, the inter-frequency and the inter-system and the speed parameter is the measurement period of the intra-frequency, the inter-frequency and the inter-system of the UE. If the acquired intra-frequency measurement period is less than the preset intra-frequency minimal measurement period, the UE performs a measurement according to the intra-frequency minimal measurement period. If the acquired inter-frequency measurement period is less than the preset inter-frequency minimal measurement period, the UE performs a measurement according to the inter-frequency minimal measurement period.

Embodiment 4
The embodiment of the present disclosure provides a method for UE to report a measurement result. The method below is described by taking a UE of an LTE system as an example, wherein the measurement parameter is specifically a DRX cycle speed factor. Specifically, as shown in FIG. 5, the method includes:
S501, determining a moving speed state of the UE, and determining a DRX cycle speed factor according to the moving speed state.
The UE may determine the moving speed state of the UE according to the number of switched or residing cells within a period. For example, the UE may acquire its own moving speed state according to the number of switched cells within a period. When the UE moves in an urban environment, coverage of a cell is relatively small, and distribution of base stations is relatively dense. If the number of the switched cells of the UE every 10 minutes is not less than 5, and the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is not less than 3, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is less than 3, the moving speed state of the UE is considered as a normal moving speed state. When the UE moves in a suburban environment, coverage of a cell is relatively large, and distribution of base stations is relatively sparse. If the number of switched cells of the UE every 10 minutes is 2, and the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is 1, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is not more than 1, the moving speed state of the UE is a normal moving speed state.
Certainly, the UE may determine its own moving speed state by adopting other methods, and then define a specific high moving speed state, medium moving speed state and normal moving speed state by adopting the corresponding method, which is not specifically limited in the present disclosure.
Correspondingly, if the moving speed state is the high moving speed state, the determined DRX cycle speed factor is a high moving speed state DRX cycle speed factor; if the moving speed state is the medium moving speed state, the determined DRX cycle speed factor is a medium moving speed state DRX cycle speed factor; and if the moving speed state is the normal moving speed state, the determined DRX cycle speed factor is a normal moving speed state DRX cycle speed factor.
Wherein, the DRX cycle speed factor may be configured by a base station and then sent to the UE through a dedicated signaling and/or a system broadcast message, and certainly the DRX cycle speed factor may also be pre-configured in the UE. The specific process includes: the UE receives a DRX cycle speed factor parameter set sent from the base station or a DRX cycle speed factor parameter set is pre-configured in the UE, wherein the DRX cycle speed factor parameter set includes DRX cycle speed factors of different moving speed states; and then the UE determines the DRX cycle speed factor according to the moving speed state of the UE from the DRX cycle speed factor parameter set.
S502, taking the product of a pre-configured DRX cycle of the UE and the DRX cycle speed factor as a DRX cycle related to a speed.
S503, acquiring a measurement period corresponding to the DRX cycle related to the speed according to the DRX cycle related to the speed as a measurement period of the UE.
According to the DRX cycle related to the speed, the UE acquires measurement periods corresponding to the DRX cycles related to speed of the intra-frequency, the inter-frequency and the inter-system respectively. If the acquired intra-frequency measurement period is less than the preset intra-frequency minimal measurement period, the UE performs a measurement according to the intra-frequency minimal measurement period. If the acquired inter-frequency measurement period is less than the preset inter-frequency minimal measurement period, the UE performs a measurement according to the inter-frequency minimal measurement period. Correspondingly, if the acquired inter-system measurement period is less than the preset inter-system minimal measurement period, the UE performs a measurement according to the inter-system minimal measurement period.
S504, measuring a cell to obtain a measurement result in the measurement period and reporting the measurement result to a serving base station of the UE.
According to the acquired intra-frequency measurement period, inter-frequency measurement period and inter-system measurement period, in the corresponding measurement period, respectively, the UE measures the cell to obtain the measurement result and reports the corresponding measurement result to an RRC layer of the UE, and the RRC layer of the UE accurately and timely reports a measurement result satisfying a report criterion, to the base station.
The LTE system is taken as an example for illustration in this embodiment. Certainly, this method is also applicable for other communication systems, such as TDSCDM, CDMA and the like. However, the specific DRX cycles are configured to be different for different communication systems. The specific process will not be repeated redundantly herein.
According to the method for UE to report a measurement result provided in the embodiment of the present disclosure, the DRX cycle speed factor corresponding to the moving speed state of the UE is preset, and the measurement period of the UE is acquired according to the DRX cycle speed factor and the pre-configured DRX cycle of the UE without affecting the use of the DRX cycle by other modules in the UE, so that the measurement result may be timely and accurately reported when the UE is in the high speed state, and the communication continuity of the UE is improved.
Embodiment 5
The embodiment of the present disclosure provides a UE. As shown in FIG. 6 and FIG. 7, the UE includes: a measurement parameter set acquiring unit 61, a determining unit 62, an acquiring unit 63 and a processing unit 64.
The measurement parameter set acquiring unit 61 is configured to receive a measurement parameter set sent from a base station; or
is configured to pre-configure a measurement parameter set in the UE;
the measurement parameter set includes measurement parameters of different moving speed states.
The determining unit 62 is configured to determine a moving speed state of the UE and determine a measurement parameter from the measurement parameter set acquired by the measurement parameter set acquiring unit according to the moving speed state.
The determining unit 62 of the UE may determine the moving speed state of the UE according to the number of switched or residing cells within a period. For example, the determining unit 62 may acquire its own moving speed state according to the number of switched cells within a period. When the UE moves in an urban environment, coverage of a cell is relatively small, and distribution of base stations is relatively dense. If the number of the switched cells of the UE every 10 minutes is not less than 5, the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is not less than 3, the moving speed state of the UE is considered as a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is less than 3, the moving speed state of the UE is a normal moving speed state. When the UE moves in a suburban environment, coverage of a cell is relatively large, and distribution of base stations is relatively sparse. If the number of the switched cells of the UE every 10 minutes is 2, and the moving speed state of the UE is a high moving speed state. If the number of the switched cells of the UE every 10 minutes is 1, the moving speed state of the UE is a medium moving speed state. If the number of the switched cells of the UE every 10 minutes is not more than 1, the moving speed state of the UE is a normal moving speed state.
Certainly, the determining unit 62 of the UE may determine its own moving speed state by adopting other methods and then define a specific high moving speed state, medium moving speed state and normal moving speed state by adopting the corresponding method, which is not specifically limited in the present disclosure.
Correspondingly, if the moving speed state is the high moving speed state, the measurement parameter determined from the measurement parameter set by the determining unit 62 of the UE is a high moving speed state measurement parameter; if the moving speed state is the medium moving speed state, the measurement parameter determined from the measurement parameter set by the determining unit 62 of the UE is a medium moving speed state measurement parameter; and if the moving speed state is the normal moving speed state, the measurement parameter determined from the measurement parameter set by the determining unit 62 of the UE is a normal moving speed state measurement parameter.
In this embodiment, the UE may merely determine that the moving speed state of the UE is the high moving speed state or the normal moving speed state, and certainly the UE may also determine the high moving speed state, the medium moving speed state and the normal moving speed state.
The acquiring unit 63 is configured to acquire a measurement period of the UE according to the measurement parameter determined by the determining unit 62.
The processing unit 64 is configured to measure a cell to obtain a measurement result in the measurement period of the UE acquired by the acquiring unit 63 and report the measurement result to a serving base station of the UE.
In the measurement period, the processing unit 64 of the UE measures the cell to obtain the measurement result, and then a physical layer of the UE reports the measurement result to a high-level RRC layer of the UE. The high-level RRC layer of the UE accurately and timely reports a measurement result satisfying a report criterion to the base station, so that the base station determines whether the UE needs to perform cell switching and which cell the UE needs to be switched to according to the contents of the measurement result.
Certainly, when the UE measures the cell, the UE may measure a serving cell of the UE or simultaneously measure a serving cell and a neighboring cell of the UE.
Wherein, the measurement parameter specifically may be a period parameter, a speed parameter or a .DRX cycle speed factor.
If the measurement parameter is the speed parameter, the acquiring unit 63 is specifically configured to acquire a measurement period corresponding to a DRX cycle according to a pre-configured DRX cycle of the UE;
to take the product of the measurement period corresponding to the DRX cycle and the speed parameter as the measurement period of the UE.
The product of the measurement period corresponding to the DRX cycle of the intra-frequency, the inter-frequency and the inter-system and the speed parameter is the measurement period of the intra-frequency, the inter-frequency and the inter-system of the UE. If the acquired intra-frequency measurement period is less than the preset intra-frequency minimal measurement period, the UE performs a measurement according to the intra-frequency minimal measurement period. If the acquired inter-frequency measurement period is less than the preset inter-frequency minimal measurement period, the UE performs a measurement according to the inter-frequency minimal measurement period. Correspondingly, if the acquired inter-system measurement period is less than the preset inter-system minimal measurement period, the UE performs a measurement according to the inter-system minimal measurement period.
Further, the measurement parameter may also be the DRX cycle speed factor, and the acquiring unit is specifically configured to take the product of the pre-configured DRX cycle of the UE and the DRX cycle speed factor as a DRX cycle related to a speed;
to acquire a measurement period corresponding to the DRX cycle related to the speed according to the DRX cycle related to the speed as the measurement period of the UE.
According to the DRX cycle related to the speed, the UE acquires measurement periods corresponding to the DRX cycles related to speed of the intra-frequency, the inter-frequency and the inter-system respectively. If the acquired intra-frequency measurement period is less than the preset intra-frequency minimal measurement period, the UE performs a measurement according to the intra-frequency minimal measurement period. If the acquired inter-frequency measurement period is less than the preset inter-frequency minimal measurement period, the UE performs a measurement according to the inter-frequency minimal measurement period. Correspondingly, if the acquired inter-system measurement period is less than the preset inter-system minimal measurement period, the UE performs a measurement according to the inter-system minimal measurement period.
The LTE system is taken as an example for illustration in this embodiment. Certainly, this method is also applicable for other communication systems, such as TDSCDM, CDMA and the like. However, the specific DRX cycles are configured to be different for different communication systems. The specific process will not be repeated redundantly herein.
In addition, if the measurement parameter is the period parameter, as shown in FIG. 7, the UE also includes: a configuration unit 65.
The configuration unit 65 is configured to configure period parameter threshold of an intra-frequency measurement, an inter-frequency measurement and an inter-system measurement respectively.
The acquiring unit 63 is specifically configured
to determine a calculation parameter according to the period parameter determined by the determining unit 62;
to determine whether the calculation parameter is greater than a preset period parameter threshold of the UE;
to acquire the measurement period of the UE according to the calculation parameter, if the calculation parameter is greater than the period parameter threshold;
to determine a preset minimal measurement period of the UE as the measurement period of the UE, if the calculation parameter is less than the period parameter threshold.
Wherein, the acquiring unit 63 determines the calculation parameter according to the period parameter determined by the determining unit 62, specifically including: the period parameter is determined as the calculation parameter; or the lower value of the period parameter and the pre-configured DRX cycle of the UE is acquired and the lower value is determined as the calculation parameter.
Certainly, for the intra-frequency, the inter-frequency and the inter-system, the acquiring unit 63 needs to acquire an intra-frequency measurement period, an inter-frequency measurement period and an inter-system measurement period respectively.
For acquiring the intra-frequency measurement period, specifically, a threshold of an intra-frequency measurement period parameter configured by the configuration unit 65 may be 0.04 s. If the calculation parameter is greater than the threshold of the intra-frequency measurement period parameter, the acquiring unit 63 is configured to acquire the product of a first natural number N1 and the calculation parameter as the intra-frequency measurement period of the UE, wherein the N1 is a preset natural number sent from a base station to the UE according to the high moving speed state through a dedicated signaling and/or a system broadcast message, and certainly the N1 may also be pre-configured in the UE, specifically as shown in table 1.
For the inter-frequency measurement period, specifically, a threshold of an inter-frequency period parameter configured by the configuration unit 65 may be 0.08 s. If the calculation parameter is greater than the threshold of the inter-frequency measurement period parameter, the acquiring unit 63 is configured to acquire the product of a second natural number N2, the number of inter-frequency layers Nfreq and the calculation parameter as the inter-frequency measurement period of the UE, wherein the N2 is a natural number preset by the base station according to different moving speed states and then sent to the UE through a dedicated signaling and/or a system broadcast message, and certainly the N2 may also be pre-configured in the UE; and the Nfreq is the number of the inter-frequency layers which need to be measured and are acquired by the UE through a system broadcast message and/or a dedicated signaling received from the base station, and the number of the inter-frequency layers Nfreq is the sum of the number of the frequency layers of the inter-frequency of the common-system and the number of the inter-system frequency layers of the UE. For this embodiment, the number of the inter-frequency layers indicates the sum of the number of the frequency layers of the inter-frequency of the LTE system and the number of the frequency layers of the non-LTE system, specifically as shown in table 2.
For the inter-system measurement period, a threshold of the inter-system measurement period configured by the configuration unit 65 may be 0.128 s. If the calculation parameter is greater than the inter-system measurement period threshold, the acquiring unit 63 is configured to acquire the product of a third natural number N3, the number of inter-frequency layers Nfreq and the calculation parameter as the inter-system measurement period of the UE, wherein the N3 is a natural number preset by the base station according to different moving speed states and then sent to the UE through a dedicated signaling and/or a system broadcast message, and certainly the N3 may also be pre-configured in the UE; and the Nfreq is the number of the inter-frequency layers which need to be measured and are acquired by the UE through a system broadcast message and/or a dedicated signaling received from the base station. The number of the inter-frequency layers Nfreq is the sum of the number of the frequency layers of the inter-frequency of the common-system and the number of the inter-system frequency layers of the UE. For this embodiment, the number of the inter-frequency layers may indicate the sum of the number of the frequency layers of the inter-frequency of the LTE system and the number of the frequency layers of the non-LTE system. For the UE using the LTE system, when an interval that the UE receives inter-system information, which is configured by the base station, is 40 ms or 80 ms, the measurement periods of the inter-system corresponding to different calculation parameters corresponds to different values.
If the calculation parameter is less than the inter-frequency measurement period parameter threshold, the acquiring unit 63 is configured to determine the preset minimal measurement period as the measurement period of the UE. Correspondingly, as mentioned in table 1, table 2 and table 3, if the calculation parameter is not greater than the threshold of the intra-frequency measurement period, the intra-frequency measurement period is the preset intra-frequency minimal measurement period of the system, and specifically may be 200 ms; the inter-frequency cell measurement period is the preset inter-frequency minimal measurement period of the system, and specifically may be the product of 0.48 and the number Nfreq of the inter-frequency layers or the product of 0.24 and the number Nfreq of the inter-frequency layers; and the inter-system measurement period is determined according to the preset value of the system, for example, when the calculation parameter is not more than 0.04, if the measurement interval is not needed, the inter-system measurement period is 0.48 s, if the measurement interval is needed, the inter-system measurement period is the minimal measurement period of the inter-system. Specifically, for example, when a UTRAN (UMTS Terrestrial Radio Access Network, UMTS terrestrial radio access network) frequency point is measured and the measurement interval is not needed, the inter-system measurement period is 0.48 s; when the measurement interval is used, the inter-system measurement period is
