Patent Description:
With the development of radio communication technologies, a large number of multi-card mobile terminals have appeared on the market. The multi-card mobile phones generally have two typical use cases. In the first case, a business user has a private card and a business card, and the two cards are both used on the same mobile phone. In the second case, an ordinary user has multiple private cards used for different businesses, and the cards may be used on communication systems belonging to the same operator or different operators.

When the handover of the multi-card terminal from one communication system belonging to an operator to a communication system belonging to another operator is performed, or from a first communication system to a second communication system belonging to the same operator, the terminal needs to stop a current RRC connection in the first communication system. That is, the current service of the terminal in the first communication system will be disconnected, and the RRC connection and the service will be re-established when the terminal returns to the first communication system, which affects continuity of the service. When trying to connect to the second communication system, since the communication resources are already occupied by the first communication system, connection conflicts may be caused. In addition, the base station may continue to page the terminal after the terminal is disconnected from the first communication system, resulting in waste of paging resources of the system.

<CIT> relates to systems and methods for a wireless communication device to manage cell measurements, including, but not limited to, performing measurements based on a first measurement configuration message received from a network, receiving a second measurement configuration message from the network before the measurements based on the first measurement configuration message are completed, and continuing to perform measurements based on the first measurement configuration message after receiving the second measurement configuration message.

<CIT> relates to systems and methods 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 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.

<CIT> relates to multi-subscription multi-standby communication devices and methods for managing communication activity. A device processor of the communication device can determine a timing of an upcoming tune-away from a first subscription to a second subscription, and may determine whether an upcoming communication activity on the first subscription is a critical communication activity. The device processor may determine whether the upcoming tune-away and the upcoming communication activity will collide in response to determining that the upcoming communication activity is a critical communication activity, and may schedule one or both of the upcoming critical communication activity and the tune-away to prevent the collision in response to determining that the upcoming tune-away and the upcoming communication activity will collide.

<CIT> relates to a technique including receiving, by a MS from a first cell, a measurement configuration message including a cell individual offset (CIO) value for a second cell that causes one or more MSs within a threshold range of the second cell to send a measurement report to the first cell, sending a measurement report from the MS to the first cell indicating a handover to the second cell, receiving, by the MS from the first cell, a handover command instructing the MS to perform a random access-free handover from the first cell to the second cell, the handover command including a time offset value for the MS and a handover time indicator, and performing, by the MS, a random access-free handover from the first cell to the second cell at the time indicated by the handover time indicator and concurrently with a re-shaping of the first cell.

As illustrated in <FIG>, the radio communication system is a communication system based on cellular mobile communication technology. The radio communication system may include several terminals <NUM> and several base stations <NUM>.

The terminal <NUM> may be a device that provides voice and/or data connectivity to the user. The terminal <NUM> can communicate with one or more core networks via a radio access network (RAN). The terminal <NUM> can be an Internet of Things terminal, such as a sensor device, a mobile phone (or called a cellular phone), and a computer having the Internet of Things terminal, such as, a fixed, portable, pocket-sized, handheld, built-in computer or vehicle-mounted device, e.g., a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE).

<FIG> is a flowchart illustrating a connection configuration method according to an embodiment of the disclosure. As illustrated in <FIG>, embodiments of the disclosure provide a connection configuration method. The method includes the following.

In block S110, a time parameter is configured for a handover of a multi-card terminal from a first communication system to a second communication system.

Here, the first communication system and the second communication system may be communication systems provided by different operators, or the first communication system and the second communication system may be communication systems corresponding to the same operator but based on different communication standards, such as, global system for mobile communications (GSM) and code division multiple access (CDMA). The first communication system and the second communication system can also be communication systems of the same operator and based on the same communication standard, for example, both are new radio (NR) systems.

Here, the time parameter may be set with reference to a specific operation performed by the multi-card terminal in the second communication system, for example, paging receiving, measurement, system information reading, and performing tracking area update (TAU) in the second communication system. The value of the time parameter may be obtained according to the empirical data of the above-mentioned specific operations, or determined by analyzing current operating data of the network based on current operating conditions of the network. The configuration may be performed manually, or may be automatically performed by the base station based on preset rules.

The time parameter includes at least one of: a duration, a starting time, and an ending time, and various time parameters of a departure duration in which the multi-card terminal leaves the first communication system via handover to the second communication system can be directly or indirectly determined.

In block S120, the time parameter is sent to the multi-card terminal.

Here, the multi-card terminal is a terminal that contains multiple subscriber identification modules. The multi-card terminal may be a terminal that contains at least two subscriber identification modules, for example, a double-card terminal or a triple-card terminal. A behavior mode of the multi-subscriber identification module terminal may be double card and double standby and single pass; double card and double standby and double pass; or triple card and triple standby. The subscriber identification module may be a subscriber identification module (SIM) card that exists in a separate individual form or an embedded subscriber identification module (e-SIM) that exists inside the terminal in an integrated form, and the like.

Here, the multi-card terminal may store the time parameter locally after receiving the time parameter, and apply the time parameter to an application flow of connection to the second communication system. The time parameter may be sent, through a broadcast signaling, to all the multi-card terminals that access the first communication system, or the time parameter is sent, through a unicast signaling, to a preset multi-card terminal that accesses the first communication system, which can be achieved through configuration by other configuration signalings (otherconfig) in the radio resource control reset signaling (RRCReconfiguration) and transmission.

The connection configuration method according to embodiments of the disclosure is applied to a network device on the network side, for example, various types of base stations, <NUM> base stations, <NUM> base stations, <NUM> base stations, macro base stations, micro base stations, or small base stations.

In this embodiment, the time parameter is configured for the handover of the multi-card terminal from the first communication system to the second communication system, and the time parameter is sent to the multi-card terminal. Therefore, reading paging or performing measurement by the multi-card terminal in the second communication system can bring a short interval of about <NUM> to the first communication system. From the perspective of the first communication system, the first communication system approximately experiences a shadow fading. Since each paging cycle will occur once, if the first communication system does not know the handover situation of the multi-card terminal, power control of the network and link adaptation algorithms may be affected, which may further cause resource waste in the first communication system. In this embodiment, the time parameter corresponding to the paging or measurement operation is configured, to enable a base station side to know the time of the handover of the multi-card terminal from the first communication system to the second communication system to perform the operations. Therefore, the problem of connection conflict and resource waste since the first communication system does not know the handover situation of the multi-card terminal is reduced.

In an embodiment, configuring the time parameter for the handover of the multi-card terminal from the first communication system to the second communication system includes: configuring different time parameters for different operations to be executed by the multi-card terminal in the second communication system; or, configuring the same time parameter for different operations to be executed by the multi-card terminal in the second communication system.

Here, in configurating different time parameters depending on different operations to be performed by the multi-card terminal in the second communication system, the different operations performed by the multi-card terminal in the second communication system include operations such as paging receiving, measuring, reading system information, and performing TAU.

For example, the base station #<NUM> of the operator #<NUM> sets, for the double card terminal UE#<NUM>, that a total duration in which the double card terminal UE#<NUM> can leave the first communication system is <NUM> if the double card terminal UE#<NUM> performs the TAU in the second communication system. The base station #<NUM> of the operator #<NUM> sets, for he double card terminal UE#<NUM>, that the double card terminal UE#<NUM> can leave for <NUM> if the double card terminal UE#<NUM> reads system information in the second communication system.

In configuring different time parameters for performing different operations, the time parameters can be configured depending on execution times corresponding to different operations. Performing the TAU operation by the terminal in the second communication system may bring a long interval of <NUM> to the first communication system. If a unique time parameter is universally set without distinguishing the specific operations, when the set time parameter is too long, it will cause that a duration in which the multi-card terminal disconnects from the first communication system is too long, which affects the service continuity. When the set time parameter is too short, it will cause that the operation of the multi-card terminal in the second communication system cannot be completed, which affects the realization of the communication function. In this embodiment, by configuring the time parameters for the execution times corresponding to different operations, communication continuity can be ensured, which is beneficial to achieve the realization of the communication function, improve resource utilization, and make the operation of the communication system more reliable. Here, depending on the different operations performed by the multi-card terminal in the second communication system, the same time parameter is configured. For example, the base station #<NUM> of the operator #<NUM> sets, for the double card terminal UE#<NUM>, that the total departure duration in which the double card terminal UE#<NUM> leaves the first communication system is <NUM> if the double card terminal UE#<NUM> performs the TAU or the like in the second communication system.

Here, in configuring the same time parameter for different operations, since the first communication system, the second communication system, and the multi-card terminal do not need to distinguish the time parameters corresponding to different operations, the same time parameter that is generally applicable to various operations is configured according to the different operations performed by the multi-card terminal in the second communication system. For example, in a case where the TAU operation needs <NUM> and the measurement operation needs <NUM>, the time parameter can be universally set to <NUM>. In this way, the first communication system, the second communication system, and the multi-card terminal do not need to obtain the time parameters of corresponding operation types based on specific operation types through such as distinguishing configurations, operation queries or the like at their respective ends, which simplifies the process and makes the configuration and communication process easier and more efficient.

<FIG> is a flowchart illustrating a connection configuration method according to another embodiment of the disclosure. The method further includes: in block S130, a notification that the multi-card terminal performs the handover from the first communication system to the second communication system is received.

Here, by receiving the notification that the multi-card terminal performs the handover from the first communication system to the second communication system, the first communication system can determine the starting time that the multi-card terminal leaves the first communication system via the handover to the second communication system based on the transmission time and the arrival time of the notification. The departure time when the multi-card terminal leaves the first communication system via the handover to the second communication system to perform operations, i.e., the starting calculation point of the configured time parameter can be accurately determined, thereby achieving the synchronization of timing at each end and making the communication process more reliable and efficient.

Here, if the network of the first communication system configures different time parameters for different operations executed by the multi-card terminal in the network of the second communication system, the multi-card terminal may include information about the operation to be executed in the second communication system in the notification. In this way, the first communication system can accurately and efficiently process communication procedures.

Here, if the network of the first system configures the universal configuration for the multi-card terminal without distinguishing the operations, the multi-card terminal can only inform the first network that the multi-card terminal needs to perform an operation in the second network, or inform the first network that which specific operation is to be performed.

Here, when the multi-card terminal needs to establish a communication connection with the second communication system, since the multi-card terminal has already established a communication connection with the first communication system, i.e., the communication connection resource corresponding to the multi-card terminal is already occupied by the first communication system, if the second communication system tries to occupy the communication connection resource, confliction of the resource occupation will be raised between the first communication system and the second communication system. If the communication connection with the first communication system is forcibly stopped, unknown failures and errors will occur. In this embodiment, the notification includes a notification sent when the connection between the multi-card terminal and the second communication system conflicts with the connection between the multi-card terminal and the first communication system. In this way, the connection with the first communication system that causes the confliction can be stopped in time, thereby reducing system failures or errors.

Here, the notification includes a notification indicating that the multi-card terminal needs to perform an operation in the second communication system. The multi-card terminal sends the notification indicating that the multi-card terminal needs to perform an operation in the second communication system to the first communication system to enable the first communication system to know the state of the multi-card terminal in time. In this way, relevant measures can be taken purposefully, such as the data exchange process corresponding to the multi-card terminal is temporarily disconnected to save communication resources.

Here, the notification includes a notification indicating the type of operation to be executed by the multi-card terminal in the second communication system. After the first communication system obtains the type of operation to be executed by the multi-card terminal in the second communication system, a corresponding operation time of the multi-card terminal in the second communication system can be obtained based on the configured time parameters, so that the communication process can be managed more accurately, system operation efficiency can be improved, and system resources can be saved.

<FIG> is a flowchart illustrating a connection configuration method according to another embodiment of the disclosure. The method further includes: a block S140 of disconnecting the first communication system from the multi-card terminal, in response to that a connection between the multi-card terminal and the second communication system conflicts with a connection between the multi-card terminal and the first communication system.

Here, when the multi-card terminal needs to establish a communication connection with the second communication system, since the multi-card terminal has already established a communication connection with the first communication system, i.e., the communication connection resource corresponding to the multi-card terminal is already occupied by the first communication system, if the second communication system tries to occupy the communication connection resource, confliction of the resource occupation will be raised between the first communication system and the second communication system. In this embodiment, when the connection between the multi-card terminal and the second communication system conflicts with the connection with the connection between the multi-card terminal and the first communication system, the first communication system is disconnected from the multi-card terminal. By actively stopping the communication connection with the first communication system, the confliction can be reduced, and failures and system errors caused by the conflictions can be reduced.

Here, when the base station configures the multi-card terminal, the operation type corresponding to the configuration and the time parameter can be stored in the base station in the form of a table. In this way, after knowing the type of operation to be executed by the multi-card terminal in the second communication system, the duration during which the terminal leaves the first communication system can be determined in a querying manner.

In an embodiment, the data transmission with the multi-card terminal is stopped within the duration corresponding to the time parameter, which reduces errors and failures caused by operation confliction, and the corresponding system resources can be disconnected at the same time, to save resources.

<FIG> is a flowchart illustrating a connection configuration method according to another embodiment of the disclosure. Embodiments of the disclosure provide a connection configuration method. The method includes the following.

In block S210, a time parameter for performing a handover from a first communication system to a second communication system is received.

Here, the time parameter may be determined by referring to the specific operation performed by the multi-card terminal in the second communication system sent by the first communication system. For example, the time parameter can be determined based on operations such as paging receiving, measurement, system information reading, and performing TAU in the second communication system, and the setting value of the time parameter may be obtained based on empirical data of the foregoing specific operations. The setting value of the time parameter can also be determined based on a current operating condition of the network by analyzing the current operating data of the network.

In block S220, the connection with the first communication system is stopped and the handover to the second communication system is performed within a duration corresponding to the time parameter.

Here, the multi-card terminal may leave the first communication system and be connected to the second communication system via the handover, to perform operations such as paging receiving, measurement, system information reading, and performing TAU within the duration corresponding to the time parameter.

In an embodiment, a notification of performing a handover of the multi-card terminal to the second communication system is sent to the first communication system. Here, if the network of the first communication system configures different time parameters for the multi-card terminal depending on different operations executed in the network of the second communication system, the multi-card terminal may include information which operation is to be executed in the second communication system in the notification. In this way, the first communication system can accurately and efficiently process the communication process.

In an embodiment, sending the notification that the handover to the second communication system is performed to the first communication system includes:.

Here, the notification includes a notification sent by the multi-card terminal when the connection between the multi-card terminal and the second communication system conflicts with the connection between the multi-card terminal and the first communication system. In this way, the connection with the first communication system that causes the confliction can be stopped in time to system failure or error.

Here, the notification includes a notification, sent by the multi-card terminal to the first communication system, indicating that there is an operation to be executed in the second communication system. The multi-card terminal sends the notification indicating that the multi-card terminal needs to perform an operation in the second communication system to the first communication system, which enables the first communication system to know the situation of the multi-card terminal in time. Therefore, relevant measures can be taken purposefully. For example, the data interaction process corresponding to the multi-card terminal is temporarily disconnected, thereby saving communication resources.

Here, the notification includes the notification indicating an operation type of an operation to be executed in the second communication system send by the multi-card terminal to the first communication system. After the first communication system knows the type of operation to be executed by the multi-card terminal in the second communication system, based on the configured time parameter, the corresponding operation time of the multi-card terminal in the second communication system can be obtained. Therefore, the communication process can be managed more accurately, system operation efficiency can be improved, and system resources can be saved.

In an embodiment, when it is determined that different time parameters are configured for different operations in the second communication system based on the time parameters, the notification indicating the type of the operation to be executed in the second communication system is sent to the first communication system.

Here, when it is determined according to the time parameter that different time parameters are configured for different operations performed in the second communication system, a notification indicating the type of operation to be executed in the second communication system is sent to the first communication system, such that the first communication system determines, based on the operation type, the time parameter corresponding to the operation type. Based on the time parameter, the communication process can be accurately configured and managed. For example, if a certain connection needs to be disconnected, the time for disconnecting a certain connection can be set as the time parameter corresponding to the operation type, such that the resource utilization rate is the highest and the operating efficiency of the system is improved.

In an embodiment, within the duration, the data transmission with the first communication system is stopped. In this way, the confliction between the connection with the first communication system and the connection with the second communication system is reduced, and unknown errors and system failures can be reduced, which is beneficial to improving the resource utilization rate of the first communication system.
