For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0035] 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.

[0036] With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of services in future life, the Third Generation Partnership Project (3GPP) rd The 3rd Generation Partnership Project (3GPP) international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC).

[0037] On the one hand, eMBB still aims at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0038] RRC Status

[0039] In order to reduce air interface signaling and quickly restore wireless connections and data services, 5G defines a new Radio Resource Control (RRC) state, namely the RRC inactive (RRC_INACTIVE) state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state.

[0040] 1) RRC_IDLE state (abbreviated as idle state): Mobility is based on cell selection and reselection of terminal equipment, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no terminal equipment context on the base station side, and there is no RRC connection.

[0041] 2) RRC_CONNECTED state (referred to as connected state): There is an RRC connection, and there is a terminal device context on the base station side and the terminal device side. The network side knows the location of the terminal device at the specific cell level. The mobility is the mobility controlled by the network side. Unicast data can be transmitted between the terminal device and the base station.

[0042] 3) RRC_INACTIVE state (abbreviated as inactive state): Mobility is based on the cell selection reselection of the terminal device, there is a connection between the access network and the core network, the context of the terminal device exists on a base station, paging is triggered by the Radio Access Network (RAN), the paging area based on RAN is managed by RAN, and the network side knows the location of the terminal device based on the RAN paging area level. When the terminal device moves within the Radio Access Network 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.

[0043] The above three RRC states can be converted to each other. Among them, some RRC parameters on the terminal device side in the inactive state are configured through the RRC release message. The main RRC parameters are as follows:

[0044] The inactive RNTI (I-RNTI) is used to identify the inactive context of the terminal device on the base station side and is unique within the base station.

[0045] RAN Notification Area (RNA) is an area used to control the cell selection and reselection of terminal equipment in an inactive state, and is also the paging range area of ​​RAN initial paging.

[0046] RAN Paging cycle, namely RAN DRX cycle, is used to calculate the paging opportunity of RAN initial paging.

[0047] The timer for periodic RAN notification area update is periodic location update timer T380.

[0048] Next hop chaining counter (NCC) is used to determine the key used during RRC connection recovery.

[0049] When the terminal device moves within the RNA area, it does not need to notify the network side and follows the mobility behavior in the RRC idle state, that is, the cell selection and reselection principle. When the terminal device moves out of the paging area configured by the RAN, the terminal device triggers the RRC connection recovery process (that is, RRC resume procedure) and reacquires the paging area configured by the RAN. When the network side needs to transmit data to the terminal device, that is, when downlink data arrives, the base station that saves the terminal device context will trigger all cells in the RAN paging area to send a paging message to the terminal device, so that the inactive terminal device can restore the RRC connection and receive data. In addition, the terminal device in the inactive state is configured with a RAN paging area. In order to ensure the reachability of the terminal device within this area, the terminal device needs to perform periodic location updates according to the period configured by the network. The scenarios that trigger the terminal device to perform RNA updates include RNAU timer timeout or the terminal device moving to an area outside the RNA.

[0050] Dual SIM dual standby / dual network dual standby

[0051] A dual-SIM dual-standby phone means that a phone can hold two communication cards at the same time, and both communication cards are in standby mode. Dual-SIM dual-standby generally refers to dual-SIM dual-standby of the same network standard, such as dual-SIM dual-standby of GSM network, dual-SIM dual-standby of CDMA network, and dual-SIM dual-standby of PHS network.

[0052] Dual-network dual-standby means that a mobile phone can be inserted with two communication cards of different networks at the same time and be turned on at the same time. Users can make calls, receive calls and send and receive text messages at will without switching networks.

[0053] At present, mobile phones generally do not support pure dual-transmit and dual-receive (abbreviated as dual-pass), which means that the mobile phone simultaneously sends uplink and receives downlink data on two networks through two communication cards. Generally speaking, most mobile phones only support single-transmit and single-receive or single-transmit and dual-receive, which means that the mobile phone can only execute the service on one communication card at a time. However, achieving dual-pass is a trend in the development of mobile phones in the future. In 5G, for the two communication cards of mobile phones that support dual-card dual standby or dual-network dual standby, one of the communication cards can reside in the LTE cell and the other communication card can reside in the NR cell; or, both communication cards reside in the NR cell. On the other hand, the two communication cards can be communication cards of the same operator or communication cards of different operators.

[0054] At present, if one communication card in a dual-SIM phone is performing a service and the other communication card also needs to perform a service, for example, the other communication card receives a paging call and needs to receive a service, or the other communication card initiates a service, there will be a problem of conflict between the services of the two communication cards, and how to handle the service of the other communication card and how to coordinate the services of the two communication cards need to be solved. To this end, the following technical solution of the embodiment of the present application is proposed.

[0055] It should be noted that the "terminal device" in the embodiments of the present application can be a mobile phone, a tablet computer, a wearable device, etc. The terminal device has at least two communication cards, for example, the terminal device has 2 communication cards or 3 communication cards, etc. The following embodiments are described using two communication cards as an example, but are not limited thereto. The solution with more than two communication cards is also applicable to the technical solution of the embodiments of the present application.

[0056] It should be noted that the embodiments of the present application do not limit the types of the first communication card and the second communication card. For example, the first communication card and the second communication card are both Subscriber Identity Module (SIM) cards. For example, the first communication card and the second communication card are both Universal Subscriber Identity Module (USIM) cards. For example, the first communication card is a SIM card, and the second communication card is a USIM card. For example, the first communication card is a USIM card, and the second communication card is a SIM card.

[0057] On the other hand, the embodiment of the present application does not limit the network types supported by the first communication card and the second communication card. For example, the first communication card supports the LTE network (that is, the first base station corresponding to the first communication card is an LTE base station), and the second communication card supports the NR network (that is, the second base station corresponding to the second communication card is an NR base station). For example, both the first communication card and the second communication card support the NR network (that is, the first communication card and the second communication card and the second base station corresponding to the second communication card are both NR base stations).

[0058] On the other hand, the embodiment of the present application does not limit the operators to which the first communication card and the second communication card belong. For example, the first communication card and the second communication card may belong to the same operator or different operators.

[0059] Figure 2 is a flow chart of a method for negotiating communication provided in an embodiment of the present application, such as Figure 2 As shown, the method for negotiating communication includes the following steps:

[0060] Step 201: The terminal device receives a paging message sent by a first network or the terminal device triggers to initiate an RRC connection establishment process to a first network, where the first network is a network corresponding to a first communication card in the terminal device.

[0061] In an embodiment of the present application, the terminal device receives a paging message sent by the first network through a first communication card in an idle state or an inactive state, or the terminal device triggers the initiation of an RRC connection establishment process to the first network through the first communication card in an idle state or an inactive state. Here, the first network is the network corresponding to the first communication card in the terminal device.

[0062] In the embodiment of the present application, the terminal device also receives service data sent by a second network, where the second network is a network corresponding to a second communication card in the terminal device. Specifically, the terminal device receives service data sent by the second network through the second communication card in a connected state.

[0063] For example: the terminal device has a USIM-A card (i.e., the second communication card) and a USIM-B card (i.e., the first communication card), wherein the USIM-A card is in a connected state, the USIM-B card is in an idle state or an inactive state, the terminal device receives service data on the network corresponding to the USIM-A card (i.e., the second network), and the terminal device receives a paging message on the network corresponding to the USIM-B card (i.e., the first network) or triggers the initiation of an RRC connection establishment process to the network corresponding to the USIM-B card.

[0064] Reference Figure 3 , the terminal device has a first communication card and a second communication card, wherein the network corresponding to the first communication card is the first network, and the network corresponding to the second communication card is the second network. On the one hand, the terminal device can access the first network through the first communication card to perform services on the first network. On the other hand, the terminal device can access the second network through the second communication card to perform services on the second network. Here, the types of the first network and the second network can be the same or different. For example, the first network is an LTE network, and the second network is an NR network. For another example, both the first network and the second network are NR networks.

[0065] In the embodiment of the present application, the first communication card of the terminal device is in an idle state or an inactive state. The second communication card of the terminal device is in a connected state. For example, there are two USIM cards in the terminal device, namely, USIM-A card and USIM-B card. Among them, USIM-A card has ongoing services and is in a connected state; USIM-B card is in an idle state or an inactive state and receives a paging message.

[0066] It should be noted that the communication between the terminal device and the first network is realized through the first communication card, and the communication between the terminal device and the second network is realized through the second communication card. For example, there are two USIM cards in the terminal device, namely USIM-A card and USIM-B card. Among them, the terminal device can communicate with the second network through the USIM-A card, and the terminal device can communicate with the first network through the USIM-B card.

[0067] Step 202: The terminal device sends first indication information to a second network, where the first indication information is used to instruct the terminal device to request to leave the second network to communicate with the first network, and the second network is a network corresponding to a second communication card in the terminal device.

[0068] In an embodiment of the present application, after the terminal device receives a paging message sent by the first network or the terminal device triggers the RRC connection establishment process to the first network, it is necessary to establish an RRC connection with the first network (that is, the first communication card needs to enter a connected state), and communicate with the first network based on the established RRC connection. Here, the communication between the terminal device and the first network includes but is not limited to: responding to a paging message sent by the first network. For example: the terminal device sends NAS signaling to the first network, and the NAS signaling is used to notify the first network that the terminal device is conducting business on the second network and not to page the terminal device again. Since the terminal device can only communicate with one network at the same time, the terminal device needs to notify the second network that the terminal device is leaving the second network to communicate with the first network.

[0069] Specifically, the terminal device sends first indication information to the second network, where the first indication information is used to indicate that the terminal device requests to leave the second network to communicate with the first network.

[0070] In an optional manner, the first indication information is used to indicate that the terminal device requests to leave the second network for a certain period of time. During the period when the terminal device leaves the second network, the second communication card is in a connected state and the service corresponding to the second communication card is in a suspended state.

[0071] Here, during the period when the terminal device leaves the second network, the second communication card is still in a connected state, but the service corresponding to the second communication card is in a suspended state, that is, the second network temporarily does not send service data to the second communication card, but the second network still retains the RRC connection of the second communication card.

[0072] In the embodiment of the present application, after the terminal device completes the communication with the first network, it will leave the first network. Optionally, the terminal device will return to the second network and continue to communicate with the second network, for example, continue to receive service data of the second network. Here, after the terminal device leaves the first network, the first communication card enters an idle state or an inactive state.

[0073] In an optional manner, after step 202, the method further includes the following steps:

[0074] The terminal device starts a first timer after receiving the first configuration information sent by the second network, the first configuration information is used to determine the inactive state configuration of the second communication card, and the duration of the first timer is T1.

[0075] In an optional manner, the T1 duration is indicated by the first indication information. In another optional manner, the T1 duration is configured by the second network, specifically, the T1 duration is included in the first configuration information; or, the T1 duration and the first configuration information are configured to the terminal device together.

[0076] A) If the first timer times out, the second communication card of the terminal device enters an inactive state from a connected state, and starts a periodic location update timer based on the inactive state configuration of the second communication card.

[0077] B) If the terminal device leaves the first network and returns to the second network before the first timer times out, the terminal device stops the first timer and releases the inactive configuration of the second communication card.

[0078] In one example, the inactive state configuration of the second communication card can be called suspendconfig, and suspendconfig is used to indicate the configuration information when the second communication card enters the inactive state. Here, the configuration information in the inactive state includes at least one of the following: I-RNTI, RNA, RAN paging cycle, timer for periodic RAN notification area update (i.e., periodic location update timer T380), and NCC.

[0079] In the embodiment of the present application, after the first configuration information is sent by the second network to the terminal device, the first timer is started by the second network, and the first timer is used to trigger the second network to perform the following operations:

[0080] If the first timer times out, starting a periodic location update timer;

[0081] If the terminal device leaves the first network and returns to the second network before the first timer times out, the first timer is stopped and the inactive configuration of the second communication card is released.

[0082] In one example, when the second communication card of the terminal device is in a connected state but the service corresponding to the second communication card is in a suspended state (i.e., the terminal device leaves the second network), the terminal device receives an inactive state configuration (i.e., suspendconfig) sent by the second network and starts a first timer, the duration of which is T1 (which may be indicated by the terminal device or configured by the second network). If the first timer times out, the second communication card of the terminal device enters an inactive state and starts a periodic location update timer T380, where the duration of T380 is configured in suspendconfig; if the terminal device leaves the first network and returns to the second network before the first timer times out, the terminal device automatically releases the suspendconfig of the second communication card. For the second network, after the second network sends the suspendconfig, it starts the first timer. If the first timer times out, the second network starts the periodic location update timer T380; if the terminal device leaves the first network and returns to the second network before the first timer times out, the second network automatically releases the suspendconfig of the second communication card.

[0083] In an optional method, after the terminal device leaves the first network, it measures the service cell of the second network; if the measurement result of the service cell of the second network is less than or equal to a certain threshold or a radio link failure RLF occurs in the service cell of the second network, the terminal device initiates an RRC connection recovery process or an RRC connection reconstruction process to the second network.

[0084] For example: before the terminal device leaves the network corresponding to the USIM-B card (i.e., the first network) and returns to the network corresponding to the USIM-A card (i.e., the second network), the signal quality of the second network may have changed, and the terminal device needs to detect the measurement result of the service cell corresponding to the USIM-A card. If the measurement result of the service cell is lower than a certain threshold or the service cell detects RLF, the terminal device initiates an RRC connection recovery process to the second network to restore the RRC connection, and initiates an RRC connection re-establishment process to the second network to re-establish the RRC connection.

[0085] The technical solution of the embodiment of the present application can ensure that the dual-card operations of the terminal device are coordinated with each other. In addition, after the terminal device leaves the second network, the second communication card can be controlled to enter an inactive state based on the first timer, thereby reducing the delay of the terminal device returning to the second network for service recovery.

[0088] The sending unit 402 is used to send first indication information to the second network, where the first indication information is used to instruct the terminal device to request to leave the second network to communicate with the first network, and the second network is the network corresponding to the second communication card in the terminal device.
