Patent Description:
In related arts, a processing manner adopted by multi-card user equipment (UE for short) is mainly implemented by a corresponding terminal manufacturer, leading to a problem that there are different terminal behaviors and processing manners adopted by the multi-card UEs of different manufacturers. For example, while the multi-card UE is communicating with a first communication system, the multi-card UE receives a paging signaling from the second communication system and needs to respond to a service of the second communication system. Response algorithms provided by the multi-card UEs of different manufacturers may be different.

The multi-card UEs of different manufacturers respond to the paging signaling of the second communication system with different algorithm implementations, which may cause some multi-card UEs to blindly reject or respond to the service of the second communication system, leading to poor service continuity of the multi-card UE and low service transmission efficiency.

<CIT> relates to a method for network-controlled DRVCC. In the method, a user wireless UE includes requesting handover of a voice over Internet protocol (VoIP) call from a first network to a second network, activating a second radio, continuing the voice call on the circuit switched (CS) domain of the second network, and communicating data for applications other than the voice call via the first network. The method may include determining whether a quality of the VoIP call satisfies a quality threshold, deactivating the radio continued to the second network when the quality of the VoIP call satisfies the quality threshold, and activating the second radio when the VoIP call quality does not satisfy the quality threshold.

<CIT> relates to a method for performing an adaptive access procedure on a multi-SIM wireless communication device having at least a first SIM and a second SIM associated with a shared radio frequency (RF) resource. The wireless communication device may detect that signaling on a random access channel (RACH) is required in order to establish access to a first network on a modem stack associated with the first SIM, identify a first protection window having a duration based on timing of an expected response by the first network to signaling on the RACH, and determine whether a tune-away period to decode a paging channel in a second network supported by the second SIM is scheduled to occur within the first protection window. If so, the wireless communication device may postpone signaling on the RACH until completion of the scheduled tune-away period.

The cellular telecommunications network further includes a first base station and a first UE, and the first UE is connected to the first base station by a first and second connection having resources associated with a first and second subscription respectively. The method includes: determining that the first connection and second connection relate to the first and second subscription respectively, determining that the first connection and second connection relate to the first UE, monitoring a first resource usage of one or both of the first and second connections with the first UE; and initiating a handover of one or both of the first and second connections based on the first resource usage.

<CIT> relates to a method for enabling physical layer resource sharing to improve performance on a multi-subscriber identification module (SIM) wireless communication device. The method includes detecting a communication activity on a modem stack associated with a first SIM using a first component carrier, determining whether a modem stack associated with a second SIM is connected to a network on the first component carrier, and performing carrier frequency alignment between the model stacks associated with the first and second SIMs in response to determining that the modem stack associated with the second SIM is not connected to a network on the first component carrier.

The second base station is a base station of the second communication system to which the multi-card UE is to perform the handover. When the multi-card UE <NUM> obtains the service information of the second communication system, it can be determined whether to allow the multi-card UE to perform the service handover based on the service information of the first communication system and the service information of the second communication system. Therefore, a handover configuration that is most suitable for the current network scenario can be set for the multi-card UE to perform the service handover.

In the embodiment, as described in the above blocks <NUM> to <NUM>, when the base station of the first communication system that the multi-card user equipment is currently communicating with receives the handover request signaling for requesting a handover the second communication system sent by the multi-card UE, the base station can determine whether to allow the multi-card UE to perform the handover based on the first service information corresponding to the to-be-transmitted service in the first communication system and the second service information corresponding to the to-be-transmitted service in the second communication system. The base station sends the handover response signaling carrying the handover configuration information to the multi-card UE in response to determining to allow the multi-card UE to perform the handover. Therefore, in the technical solution of the present disclosure, when the paging signal is triggered by the second communication system of the multi-card user equipment, the service information of the first communication system and the second communication system is comprehensively considered before the rejection or response to the second communication system is executed. Therefore, with the technical solutions according to the disclosure that the service of the second communication system is rejected or responded to after comprehensively considering the service information of the first communication system and the second communication system when a paging signaling triggered by the second communication system is received by the multi-card UE, such that a problem, existing in related arts, of poor service continuity and low service transmission efficiency of the multi-card UE caused by the multi-card UE blindly rejecting or responding to the service of the second communication system can be solved, thereby improving the service continuity and the transmission efficiency of the service data of the multi-card UE.

Technical solutions according to embodiments of the disclosure will be described in combination with some specific embodiments below.

<FIG> is a flowchart illustrating another service handover method according to an example embodiment, which illustrates how the first station determines whether to allow the multi-card UE to perform the handover with the above-mentioned method according to embodiments of the disclosure. As illustrated in <FIG>, the method includes the following.

In block <NUM>, a handover request signaling sent by a multi-card UE is received. The handover request signaling is configured to request a handover to the second communication system.

In block <NUM>, second service information corresponding to a to-be-transmitted service of the multi-card UE in the second communication system is obtained from the handover request signaling through analysis.

In an embodiment, implementation of the blocks <NUM> and <NUM> can refer to the descriptions of the block <NUM> in the embodiment illustrated in <FIG>, which will not be described in detail here.

In block <NUM>, a first processing priority corresponding to the to-be-transmitted service in the first communication system is determined based on the first service information and a second processing priority corresponding to the to-be-transmitted service in the second communication system is determined based on the second service information, and a block <NUM> or a block <NUM> is executed.

In an embodiment, the first base station may determine the first processing priority corresponding to the to-be-transmitted service in the first communication system and the second processing priority corresponding to the to-be-transmitted service in the second communication system based on a preset handover algorithm. The first base station may determine whether to perform a handover operation based on the first processing priority and the second processing priority. If the first processing priority is higher than the second processing priority, the first base station may determine to not perform the handover. If the first processing priority is not higher than the second processing priority, the first base station can determine to perform the handover.

In an embodiment, the first base station may determine the processing priority corresponding to the service (i.e., the first processing priority corresponding to the service in the first communication system and the second processing priority corresponding to the service in the second communication system) based on the requirements of the service data of the to-be-transmitted service on the bandwidth, the rate, the time delay, and the reliability.

In an embodiment, the preset handover algorithm used by the first base station to determine whether to allow the multi-card UE to perform a handover may be determined by a operator network based on massive statistical data. In an embodiment, the preset handover algorithm used by the first base station to determine whether to allow the multi-card UE to perform the handover may be pre-arranged by a communication protocol.

In block <NUM>, if the first processing priority is lower than the second processing priority, it is determined to allow the multi-card UE to perform the handover operation.

In block <NUM>, a handover response signaling is generated. The handover response signaling carries handover configuration information. The first service information is service information corresponding to the to-be-transmitted service of the multi-card UE in the first communication system.

In block <NUM>, if the first processing priority is not lower than the second processing priority, it is determined to not allow the multi-card UE to perform the handover.

In block <NUM>, a response signaling indicating that the multi-card UE is not allowed to perform the handover operation is sent to the multi-card UE, or sending a response signaling to the multi-card UE is refused.

In an embodiment, by sending, to the multi-card UE, the response signaling indicating that the multi-card UE is not allowed to perform the handover operation, it can clearly indicate that the multi-card UE is not allowed currently to perform the handover operation, thereby avoiding a problem of waste of signaling resources caused by repeated transmission of the handover request signaling by the multi-card UE.

In an embodiment, the response signaling indicating that the multi-card UE is not allowed to perform the handover operation may also carry indication information indicating a time period (e.g., within a preset time period) after which the multi-card UE can resend the handover request signaling.

In an embodiment, by refusing to send a response signaling to the multi-card UE, the waste of signaling resources of the first base station can be reduced.

In this embodiment, as described in the above blocks <NUM> to <NUM>, the base station can determine whether to allow the multi-card UE to perform handover based on the first service information and the second service information, and set the handover configuration for the multi-card UE in response to allowing the multi-card UE to perform the handover operation, to indicate when the multi-card UE performs the handover and when the multi-card UE perform a handover back to the first communication system. In this way, the first base station can set the handover configuration that is most suitable for the current network scenario for the multi-card UE to perform the service handover, such that a problem, existing in related arts, of poor service continuity and low service transmission efficiency of the multi-card UE caused by the multi-card UE blindly rejecting or responding to the service of the second communication system can be solved, thereby improving the service continuity and the transmission efficiency of the service data of the multi-card UE.

In an embodiment, the first base station may determine, based on the first service information, a duration required by the multi-card UE to process a service in the first communication system that needs to be processed as quickly as possible (e.g., a service with a high time delay requirement or a service with a high quality of service), to determine the expected interruption time for the multi-card UE to interrupt the to-be-transmitted service in the first communication system.

In an embodiment, the first base station may also determine a time length required by the multi-card UE to execute the service in the second communication system based on the second service information, to determine the expected time length that the multi-card UE communicates with the second communication system.

In an embodiment, if the handover request signaling sent by the multi-card UE indicates the handover configuration information recommended by the multi-card UE, the first base station may follow the handover configuration information recommended by the multi-card UE to set suitable handover configuration information for multi-card UE.

In an embodiment, if the first base station determines, based on the first service information and the second service information, that the recommended handover configuration information in the handover request signaling sent by the multi-card UE is unreasonable, the first base station can configure suitable handover configuration information for the multi-card UE based on the first service information and the second service information.

In block <NUM>, a handover response signaling carrying the handover configuration information recommended by the multi-card UE is generated.

In this embodiment, through the above blocks <NUM> and <NUM>, the first base station can configure the suitable handover configuration information for the multi-card UE based on the handover request signaling sent by the UE, thereby avoiding the poor continuity of transmitting the service data caused by unreasonable service handover of the multi-card UE.

<FIG> is a flowchart illustrating a service handover method according to an exemplary embodiment. The service handover method can be applied to a base station device. As illustrated in <FIG>, the service handover method includes the following blocks <NUM>-<NUM>.

In block <NUM>, a handover request signaling is generated based on the second service information of the to-be-transmitted service in the second communication system. The handover request signaling is configured to request the first base station to allow the multi-card UE to perform a handover to the second communication system. The handover request signaling carries the second service information corresponding to the to-be-transmitted service of the multi-card UE in the second communication system.

In an embodiment, the second service information may include the service type of the to-be-transmitted service of the multi-card UE in the second communication system. For example, the service type of the to-be-transmitted service is URLLC service or the service type of the to-be-transmitted service is a video communication service. In another embodiment, the second service information may include the quality of service class identifier of the to-be-transmitted service. For example, the quality of service class identifier of the to-be-transmitted service is <NUM>. In another embodiment, the second service information may also include the data volume of the to-be-transmitted service. For example, the data volume of the to-be-transmitted service of the second service information exceeds a maximum buffered data volume.

In an embodiment, the second service information may also include other information representing the service characteristics of the to-be-transmitted service in the second communication system, such as the periodicity of service data transmission and the requirements of the service data on the bandwidth, the rate, the time delay, and the reliability.

In block <NUM>, the handover request signaling is sent to the first base station. The first base station is a base station of the first communication system with which the multi-card UE is currently communicating.

In an example scenario, as illustrated in <FIG>, a first base station <NUM>, a second base station <NUM>, and a multi-card UE <NUM> are included. The first base station <NUM> is a base station of the first communication system that is currently communicating with the multi-card UE. The second base station is a base station of the second communication system to which the multi-card UE is to perform the handover. When the multi-card UE <NUM> obtains the service information of the second communication system, the multi-card UE <NUM> can send the handover request signaling to the first base station <NUM>, and the handover operation is executed or not executed based on the response from the first base station <NUM>. Therefore, a handover configuration that is most suitable for the current network scenario can be set for the multi-card UE to perform the service handover.

In the embodiment, as described in the above blocks <NUM> and <NUM>, when the multi-card UE obtains the service information of the second communication system, the multi-card UE can send the handover request signaling to the first base station of the first communication system that is currently communicating with the multi-card UE. It is determined whether to allow the multi-card UE to perform the handover based on the first service information corresponding to the to-be-transmitted service and the second service information corresponding to the to-be-transmitted service in the second communication system. In this way, a problem, existing in related arts, of poor service continuity and low service transmission efficiency of the multi-card UE caused by the multi-card UE blindly rejecting or responding to the service of the second communication system can be solved, thereby improving the service continuity and the transmission efficiency of the service data of the multi-card UE.

<FIG> is a flowchart illustrating another service handover method according to an example embodiment, which illustrates how the multi-card UE generates the handover request signaling containing the handover configuration information with the above method according to embodiments of the disclosure. As illustrated in <FIG>, the method includes the following.

In block <NUM>, an expected interruption time is determined for the multi-card UE to interrupt the to-be-transmitted service in the first communication system based on the first service information, and/or an expected time length that the multi-card UE is in the second communication system is determined based on the second service information.

In an embodiment, after obtaining the second service information of the to-be-transmitted service in the second communication system, the multi-card UE may further obtain the first service information of the to-be-transmitted service in the first communication system. Therefore, the multi-card UE can determine, based on the first service information, a duration required by the multi-card UE to process a service in the first communication system that needs to be processed as quickly as possible (e.g., services with high delay requirements or services with high quality of service), to determine the expected interruption time for the multi-card UE to interrupt the to-be-transmitted service in the first communication system.

In an embodiment, the multi-card UE may also determine a time length required by the multi-card UE to execute the service in the second communication system based on the second service information, to determine the expected time length that the multi-card UE communicates with the second communication system.

In an embodiment, the multi-card UE may also determine the expected interruption time that the multi-card UE interrupts the to-be-transmitted service in the first communication system and the expected time length that the multi-card UE communicates with the second communication system by comprehensively considering the first service information and the second service information.

In block <NUM>, the expected interruption time and/or the expected time length are determined as the handover configuration information recommended by the multi-card UE.

In block <NUM>, the handover configuration information recommended by the multi-card UE is added to the handover request signaling.

In block <NUM>, the handover request signaling is sent to the first base station. The first base station is a base station of the first communication system that is currently communicating with the multi-card UE.

In this embodiment, as described in blocks <NUM> to <NUM>, the multi-card UE can determine the recommended handover configuration information based on the first service information in the first communication system and the second service information in the second communication system, and send the recommended handover configuration information to the first base station through the handover request signaling. In this way, the first base station can directly set a reasonable handover configuration for the multi-card UE based on the handover configuration information recommended by the multi-card UE.

<FIG> is a flowchart illustrating another service handover method according to an exemplary embodiment, which illustrates how the multi-card UE executes the service handover operation with the above-mentioned method according to embodiments of the disclosure. As illustrated in <FIG>, the method includes the following.

In an embodiment, the descriptions of the blocks <NUM> and <NUM> can refer to the descriptions of the blocks <NUM> and <NUM> of the embodiment illustrated in <FIG>, which will not be described in detail here.

In block <NUM>, a response signaling returned by the first base station based on the handover request signaling is monitored within a set time interval, and a block <NUM> or a block <NUM> is performed.

In block <NUM>, if a monitoring result is monitoring that there is the handover response signaling, the handover configuration information is obtained from the handover response signaling through analysis.

In block <NUM>, a handover operation is performed based on the handover configuration information.

In an embodiment, as described in blocks <NUM> to <NUM>, when the multi-card UE monitors that there is the handover response signaling returned by the first base station for allowing the handover, the multi-card UE can trigger an operation when to perform the handover to the second communication system based on the handover configuration information and trigger an operation when to perform the handover back to the first communication system based on the handover configuration information for triggering the operation when to perform the handover to the second communication system.

In this embodiment, as described in blocks <NUM>-<NUM>, it can be determined whether the service handover operation can be performed based on the monitoring result. A problem, existing in related arts, of poor service continuity and low service transmission efficiency of the multi-card UE caused by the multi-card UE blindly rejecting or responding to the service of the second communication system can be solved, thereby improving the service continuity and the transmission efficiency of the service data of the multi-card UE.
