[0034] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0035] Three RRC states

[0036] In the 5G network environment, in order to reduce air interface signaling and quickly restore wireless connections and data services, a new RRC state is defined, namely the RRC inactive (RRC_INACTIVE) state. This state is different from the RRC idle (RRC_IDLE) state and the RRC connected (RRC_CONNECTED) state.

[0037] The following describes the three RRC states in the 5G network environment:

[0038] 1) RRC_IDLE state (hereinafter referred to as idle state): Mobility is based on UE cell selection and reselection, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no UEAS context on the base station side. There is no RRC connection.

[0039] 2) RRC_CONNECTED state (hereinafter referred to as connected state): There is an RRC connection, and the base station and the UE have a UE AS context. The network side knows the location of the UE at the specific cell level. The mobility is the mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.

[0040] 3) RRC_INACTIVE state (hereinafter referred to as inactive state): Mobility is based on UE cell selection reselection, there is a connection between the Radio Access Network (RAN) and the Core Network (CN), the UEAS context exists on a base station, paging is triggered by the RAN, the RAN-based paging area is managed by the RAN, and the network side knows the UE's location based on the RAN paging area level.

[0041] Inactive state features

[0042] When the UE is in an inactive state, it has the following characteristics: 1) The connection between the RAN and the CN is maintained; 2) The UE and at least one base station save the AS context; 3) The UE is reachable to the RAN side, and the relevant parameters are configured by the RAN; 4) When the UE moves within the RAN Notification Area (RNA) configured by the RAN, it does not need to notify the network side, but when it moves out of the RNA, it needs to notify the network side; 5) The UE moves within the RNA according to the cell selection reselection method.

[0043] When the UE is in an inactive state, the following situations trigger the UE to return to the idle state: 1) when receiving the CN initial paging message; 2) when initiating an RRC recovery request, starting timer T319, if the timer times out; 3) when MSG4 integrity protection verification fails; 4) when the cell reselects to other radio access technologies (Radio Access Technology, RAT); 5) entering the state of residing in any cell.

[0044] When the UE is in an inactive state, the network side will configure the inactive state configuration parameters for the UE through RRC dedicated signaling (such as RRC release message). The main configuration parameters include: 1) Inactive Radio Network Temporary Identifier (I-RNTI), I-RNTI is used to identify the UE inactive state context on the base station side, and I-RNTI is unique within the base station. 2) RNA, RNA is used to control the area where the UE performs cell selection reselection in an inactive state, and is also the paging range area for RAN initial paging. 3) RAN Discontinuous Reception Cycle (RAN DRX cycle), RAN DRX cycle is used to calculate the paging timing of RAN initial paging. 4) RAN Notification Area Update Periodicity (RNA Update periodicity, RNAU periodicity), RNAU periodicity is used to control the period for the UE to perform periodic RAN location update. 5) Next hop Chaining Counter (NCC), NCC is used for the key used in the RRC connection recovery process.

[0045] When the UE moves within the RNA area, it does not need to notify the network side and follows the mobility behavior in the idle state, that is, the cell selection and reselection principle. When the UE moves out of the paging area configured by the RAN, it will trigger the UE to restore the RRC connection and reacquire the paging area configured by the RAN. When the UE has downlink data arriving, the base station that maintains the connection between the RAN and the CN for the UE will trigger all cells in the RAN paging area to send a paging message to the UE, so that the inactive UE can restore the RRC connection and receive data. On the other hand, the inactive UE is configured with a RAN paging area. In order to ensure the reachability of the UE within this area, the UE needs to perform periodic location updates according to the period configured by the network (based on the RNAU timer). Therefore, the scenarios that trigger the UE to perform RNAU include the RNAU timer timing out or the UE moving to an area outside the RNA.

[0046] The mobility behavior of UE in idle and inactive states follows the cell selection and reselection principle. Specifically, in the process of cell selection and reselection, in order to meet the load balancing, the UE defines a cell reselection strategy based on frequency priority. In the reselection of cells with the same frequency or different frequencies with the same frequency priority, the R criterion is used to reselect cells, that is, the cells are sorted according to their signal quality, and the cell with the best signal quality is selected as the candidate reselection target cell. For cells with high frequency priority, as long as the cell signal quality meets a certain threshold, it will be reselected to a cell with a high frequency priority. For cells with low frequency priority, they will only be reselected when the signal quality of the serving cell is lower than a certain threshold.

[0047] Dual SIM card terminal

[0048] Dual SIM dual standby means that a terminal can hold two user identification cards at the same time, and these two user identification cards are in standby mode. Dual SIM dual standby on the market generally refers to dual SIM dual standby of the same network standard, i.e. GSM network dual SIM dual standby, or CDMA network dual SIM dual standby, etc. Dual network dual standby means that a terminal can be inserted with user identification cards of two different networks at the same time and be turned on at the same time, so that users can make calls, receive calls, and send and receive text messages at will without switching networks.

[0049] At present, the terminal's capabilities generally do not support pure dual-channel, which refers to dual transmission and dual reception (Dual UL / DL), that is, the UE transmits uplink data services and downlink data services on two networks through two user identification cards at the same time. Generally speaking, most current terminals only support Single UL / DL or Single UL / Dual DL, which means that the UE can only execute the service on one user identification card at a time.

[0050] In 5G, one of the dual SIM cards can reside in an LTE cell, the other SIM card can reside in an NR cell, or both SIM cards can reside in an NR cell. On the other hand, the two SIM cards can belong to the same operator or different operators.

[0051] At present, the mobility management of two user identity cards is performed independently, for example, the cells where the two user identity cards reside and the measurements and mobility behaviors in the idle state are performed independently. If the two user identity cards belong to the same operator, the mobility management of the two user identity cards can be jointly processed, and the following technical solutions of the embodiments of the present application are proposed for this purpose.

[0052] Figure 2 A flow chart of a mobility management method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the mobility management method includes the following steps:

[0053] Step 201: The terminal determines that the mobility management of the first user identity card and the second user identity card can be jointly processed.

[0054] In the embodiment of the present application, the terminal can be any device that can communicate with the network, such as a mobile phone, a tablet computer, a notebook, a vehicle-mounted terminal, a wearable device, etc.

[0055] In an embodiment of the present application, the terminal supports dual-SIM dual-standby. Specifically, the terminal can be inserted with two user identity cards, namely a first user identity card and a second user identity card, wherein the networks in which the first user identity card and the second user identity card can reside can be the same type of network or different types of networks, for example, the first user identity card can reside in an LTE cell, the second user identity card can reside in an NR cell, or both user identity cards can reside in an NR cell.

[0056] In the embodiment of the present application, the first user identity card and the second user identity card may both be Subscriber Identification Module (SIM) cards, or both be Universal Subscriber Identity Module (USIM) cards, or one may be a SIM card and the other may be a USIM card. The embodiment of the present application does not limit the types of the first user identity card and the second user identity card.

[0057] It should be noted that the solutions recorded in the embodiments of the present application are all based on dual cards as an example, and the present application is not limited thereto. The technical solutions of the embodiments of the present application are also applicable to the future multi-card situation. For example, the terminal can insert three user identity cards, namely the first user identity card, the second user identity card and the third user identity card.

[0058] In an embodiment of the present application, the terminal determines whether the mobility management of the first user identity identification card and the second user identity identification card can be jointly processed in the following manner: the terminal determines whether the first user identity identification card and the second user identity identification card have an association relationship; if the first user identity identification card and the second user identity identification card have an association relationship, the terminal determines that the mobility management of the first user identity identification card and the second user identity identification card can be jointly processed.

[0059] Here, the first user identity card and the second user identity card have an associated relationship, including: 1) the card number corresponding to the first user identity card and the card number corresponding to the second user identity card belong to the same operator; and / or, 2) the core network registered by the first user identity card and the core network registered by the second user identity card belong to the same core network, such as the 5G core network (5GC).

[0060] Step 202: The terminal sends first indication information to the network side, where the first indication information is used to indicate that the mobility management of the first user identity identification card and the second user identity identification card can be jointly processed.

[0061] In the embodiment of the present application, the purpose of the terminal sending the first indication information to the network side is to enable the base station to know that the mobility management of the first user identity identification card and the second user identity identification card can be jointly processed. The terminal can use any of the following methods to implement sending the first indication information to the network side:

[0062] Method 1: The terminal sends a first indication message to an access and mobility management function (AMF); after the first user identity card and the second user identity card enter a connected state, the first indication message is sent by the AMF to a base station. Furthermore, the first indication message is carried in a registration message or a location update message.

[0063] For example, the terminal instructs the AMF in a registration message or a location update message that the mobility management of the first user identity card and the second user identity card can be jointly processed. The AMF can instruct the base station that the mobility management of the first user identity card and the second user identity card can be jointly processed after both cards enter the connection.

[0064] In an optional implementation, when the terminal detects that the first user identity card or the second user identity card is removed from the terminal, the terminal sends a second indication message to the AMF, and the second indication message is used to indicate that the mobility management of the first user identity card and the second user identity card is processed independently or the joint processing of the mobility management of the first user identity card and the second user identity card is canceled. Further, the second indication message is carried in a re-registration message or a location update message.

[0065] For example: when the terminal detects that any card has been removed from the terminal, the terminal sends a location update message or a re-registration message to the AMF, indicating through the location update message or the re-registration message that the joint processing of the two cards by the AMF has been canceled (or released).

[0066] Mode 2: After the first user identity identification card and the second user identity identification card enter a connection state, the terminal sends first indication information to the base station.

[0067] In the embodiment of the present application, when the mobility management of the first user identity identification card and the second user identity identification card can be jointly processed, the terminal jointly processes the mobility management of the first user identity identification card and the second user identity identification card.

[0068] It should be noted that the processing of mobility management mainly involves the processing of the access stratum (AS). The processing of the access stratum mainly includes: measurement, cell selection, radio resource management, paging, location update, etc. Optionally, the processing of mobility management may also include the processing of the non-access stratum (NAS). The processing of the non-access stratum mainly includes: session management, user management, etc.

[0069] In the embodiment of the present application, joint processing of the mobility management of the first user identity identification card and the second user identity identification card can be implemented in the following manner.

[0070] ● Joint processing of measurements and cell selection and reselection evaluation (i.e. mobility decision)

[0071] First, the terminal determines the primary card and the secondary card from the first user identity card and the second user identity card. Here, the primary card can be determined in the following ways: 1) the terminal determines the user identity card with dedicated mobility control parameters from the first user identity card and the second user identity card, and uses the user identity card as the primary card; or, 2) the terminal receives the second configuration information sent by the network side, and determines whether the primary card is the first user identity card or the second user identity card based on the second configuration information; or, 3) the terminal determines whether the primary card is the first user identity card or the second user identity card based on the implementation of the terminal. Here, the secondary card can also be called a non-primary card.

[0072] For example: the terminal determines which of the two USIM cards is the primary card (the other card is naturally the secondary card), and the primary card dominates the measurement and mobility decision of the cell. Among them, the USIM card with dedicated mobility control parameters is used as the primary card, or the AMF or base station configures which USIM card is the primary card, or the terminal determines which USIM card is the primary card based on its own implementation.

[0073] ◆The terminal is in idle or inactive state

[0074] The terminal ignores or turns off the mobility measurement operation and the cell selection and reselection evaluation operation corresponding to the secondary card, wherein the cell where the secondary card resides is determined based on the cell where the primary card resides.

[0075] Here, the mobility measurement operation and cell selection reselection evaluation operation corresponding to the secondary card refer to: the mobility measurement operation and cell selection reselection evaluation operation of the secondary card's resident cell. The cell where the secondary card resides and the target cell to be reselected change with the resident cell and the target cell to be reselected of the primary card, that is, the secondary card resides in the same cell as the primary card.

[0076] Here, the terminal being in an idle state or an inactive state means that the first user identity card and the second user identity card are in an idle state or an inactive state.

[0077] ◆The terminal is in a connected state

[0078] The terminal ignores or turns off the mobility measurement configuration corresponding to the secondary card; the terminal receives the third indication information sent by the base station, and the third indication information is used to instruct the terminal to switch the main card and the secondary card to the same target cell at the same time, and the main card and the secondary card correspond to the same wireless resource configuration.

[0079] Here, the mobility measurement configuration corresponding to the secondary card refers to: the connection state mobility measurement configuration of the serving cell where the secondary card is located. The base station switches the primary card and the secondary card simultaneously and switches to the same target cell, and configures the same radio resource configuration.

[0080] In an optional implementation, the terminal receives first configuration information sent by the base station, and the first configuration information is used to determine the mobility measurement configuration corresponding to the primary card. In specific implementation, when the terminal or AMF indicates to the base station that the mobility management of the two cards can be jointly processed, the base station only configures the corresponding mobility measurement configuration for one of the cards (generally the primary card).

[0081] It should be noted that, since the terminal is in a connected state, the mobility measurement configuration configured by the base station refers to the mobility measurement configuration in the connected state.

[0082] In an optional implementation, the terminal sends fourth indication information to the base station, and the fourth indication information is used to request to simultaneously perform the switching of the primary card and the secondary card and / or configure the same wireless resource configuration for the primary card and the secondary card. Further, the fourth indication information is carried in a measurement report message or a terminal auxiliary information message.

[0083] For example, the terminal requests the base station to perform synchronous switching of the RRC connections corresponding to the two cards and / or requests the base station to configure the same radio resource configuration for the RRC connections corresponding to the two cards through the fourth indication information. The terminal can carry the fourth indication information in the measurement report message or the terminal assistance information message.

[0084] Here, the terminal being in a connected state means that the first user identity card and the second user identity card are in a connected state.

[0085] ●Joint processing of location updates

[0086] When the terminal is in an inactive state, the terminal receives an RRC release message sent by a base station, the RRC release message carries third configuration information and fifth indication information, the third configuration information is used to determine an inactive state configuration parameter, and the fifth indication information is used to indicate that the inactive state configuration parameter is applicable to the first user identity identification card and the second user identity identification card; the terminal performs location update of the first user identity identification card and the second user identity identification card based on the RRC release message.

[0087] Here, the terminal being in an inactive state means that the first user identity card and / or the second user identity card are in an inactive state.

[0088] Here, the inactive configuration parameter includes at least one of the following: a redirection configuration parameter and a mobility control parameter.

[0089] Here, executing the location update of the first user identity card and the second user identity card includes: executing a periodic tracking area update (Tracking Area Update, TAU) and / or a cross-border TAU of the first user identity card and the second user identity card.

[0090] In specific implementation, after the base station learns that the mobility management of the two cards can be jointly processed, when one of the cards is in an inactive state or both cards are in an inactive state, the base station configures the inactive state configuration parameters through an RRC release message, and carries fifth indication information in the RRC release message, and the fifth indication information is used to indicate that the inactive state configuration parameters are applicable to the two cards being jointly processed. After receiving the RRC release message, the terminal obtains the inactive state configuration parameters for the joint processing, and performs periodic TAU and / or cross-border TAU of the two cards based on the inactive state configuration parameters.

[0091] In an optional implementation, the terminal sends an RRC recovery request message to the base station, the RRC recovery request message carries sixth indication information, and the sixth indication information is used to indicate that the terminal supports joint processing of mobility management of the first user identity card and the second user identity card. In this way, the base station can choose to perform joint processing. The joint processing relationship (i.e., whether the joint processing can be performed or not) or the configuration of the two cards can be stored in the inactive AS context of the terminal.

[0092] ●Joint processing of RAN paging and RNAU

[0093] ◆When the terminal is in an inactive state, a first event and a second event occur simultaneously. The first event refers to that the terminal receives a first paging message for the first user identity card, and the first paging message is triggered by the access network; the second event refers to an RNAU event; the terminal sends an RRC recovery request message to the base station, and the RRC recovery request message carries seventh indication information, and the seventh indication information is used to indicate the execution of RNAU while responding to the first paging message.

[0094] Here, the terminal being in an inactive state means that the first user identity card and the second user identity card are in an inactive state.

[0095] In an optional implementation manner, the RRC recovery request message further carries fourth configuration information, and the fourth configuration information is used to determine the inactive configuration information of the second user identity card.

[0096] For example: when both USIM cards (USIM A and USIM B) are in an inactive state, USIM A RANpaging (i.e., the first event) and USIM B RNAU (i.e., the second event) occur simultaneously, then USIM A can jointly process USIM B's RNAU when responding to paging. That is, the terminal carries the seventh indication information in the RRC recovery request message, and the seventh indication information is used to indicate the joint processing of USIM A RAN paging and USIM B RNAU. Optionally, the terminal carries the suspension configuration information (i.e., inactive state configuration information) of USIM B in the RRC recovery request message. At this point, USIM B's RNAU ends, and USIM A continues to execute the RRC recovery process to respond to RAN paging.

[0097] ◆When the terminal is in an inactive state, a first event and a second event occur simultaneously. The first event refers to the terminal receiving a first paging message for the first user identity card, and the first paging message is triggered by the access network; the second event refers to an RNAU event; if the priority of the first event is higher than the priority of the second event, the terminal executes RNAU after responding to the first paging message; if the priority of the second event is higher than the priority of the first event, the terminal executes RNAU and then responds to the first paging message.

[0098] Here, the terminal being in an inactive state means that the first user identity card and the second user identity card are in an inactive state.

[0099] For example: when two USIM cards (USIM A and USIM B) are in an inactive state, USIM A RANpaging (i.e., the first event) and USIM B RNAU (i.e., the second event) occur at the same time, the priority of USIM B RNAU is higher than the priority of USIM A RAN paging, and USIM B RNAU is executed first, and then USIM A RAN paging is responded to; or, the priority of USIM A RAN paging is higher than the priority of USIM B RNAU, and USIM A RAN paging is responded to first, and then USIM B RNAU is executed.

[0100] ●Joint processing of access control

[0101] In the case where the first user identity identification card and the second user identity identification card need to access the network side at the same time: if the service priority corresponding to the first user identity identification card is higher than the service priority corresponding to the second user identity identification card, the access control operation corresponding to the second user identity identification card is executed after the access control operation corresponding to the first user identity identification card is executed; if the service priority corresponding to the second user identity identification card is higher than the service priority corresponding to the first user identity identification card, the access control operation corresponding to the first user identity identification card is executed after the access control operation corresponding to the second user identity identification card is executed; wherein, the access result corresponding to the first user identity identification card is independent of the access result corresponding to the second user identity identification card.

[0102] For example: USIM A and USIM B both need to access the network. If the service priority of USIM A is higher than that of USIM B, when USIM A is barred after performing the same access control (UAC) operation, USIM B can continue to perform the UAC operation. If the UAC passes, USIM B can access the network. It can be seen that the UAC operation of USIM B is not affected by the access result of USIM A.

[0103] ●Joint processing of CN paging and RAN paging

[0104] Here, CN paging refers to paging triggered by the core network, and RAN paging refers to paging triggered by the access network.

[0105] When the third event and the fourth event occur at the same time, the third event refers to that the terminal receives a first paging message for the first user identity card, and the first paging message is triggered by the core network; the fourth event refers to that the terminal receives a second paging message for the second user identity card, and the second paging message is triggered by the access network: 1) if the service priority corresponding to the first paging message is higher than the service priority corresponding to the second paging message, the terminal responds to the first paging message; if the service priority corresponding to the second paging message is higher than the service priority corresponding to the first paging message, the terminal responds to the second paging message; or, 2) the terminal responds to the first paging message; or, 3) the terminal responds to the second paging message.

[0106] For example: if USIM A CN paging (i.e., the third event) and USIM B RAN paging (i.e., the fourth event) occur at the same time, the terminal selects which USIM card's paging message to respond to based on the service priority in the paging message. Specifically, the terminal selects to respond to the paging message with a higher priority. Alternatively, the priority of RAN paging is defined to be higher than that of CN paging, and the terminal does not need to make a judgment and directly responds to USIM B RAN paging. Alternatively, the priority of CN paging is defined to be higher than that of RAN paging, and the terminal does not need to make a judgment and directly responds to USIM A CN paging.
