[0043] 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.

[0044] 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).

[0045] 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.

[0046] RRC Status

[0047] 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.

[0048] in,

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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:

[0053] 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.

[0054] 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.

[0055] RAN Paging cycle, namely RAN DRX cycle, is used to calculate the paging opportunity of RAN initial paging.

[0056] The timer for periodic RAN notification area update is periodic location update timer T380.

[0057] Next hop chaining counter (NCC) is used to determine the key used during RRC connection recovery.

[0058] 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.

[0059] Dual SIM dual standby / dual network dual standby

[0060] 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.

[0061] 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.

[0062] 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.

[0063] The terminal device in the inactive state will perform RAN periodic location update and CN periodic location update, and the terminal device in the idle state will perform CN periodic location update. For dual-SIM mobile phones, the communication card in the inactive state will perform RAN periodic location update and CN periodic location update, and the communication card in the idle state will perform CN periodic location update. The states of the two communication cards can be: 1) Both communication cards are in the idle state; 2) Both communication cards are in the inactive state; 3) One communication card is in the idle state and the other communication card is in the inactive state. If the two communication cards trigger the periodic location update at the same time, the periodic location updates of the two communication cards will conflict. For terminal devices that support a single transmission channel (one TX), it is necessary to coordinate the triggering time point and / or period of the periodic location update so that the events that trigger the periodic location update at the same time are staggered as much as possible. To this end, the following technical solutions of the embodiments of the present application are proposed.

[0064] 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.

[0065] 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.

[0066] 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).

[0067] 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.

[0068] Figure 2 This is a flow chart of the location update method provided in the embodiment of the present application. Figure 1 ,like Figure 2 As shown, the location updating method comprises the following steps:

[0069] Step 201: When a conflict occurs between the periodic location update of the first communication card of a terminal device and the periodic location update of the second communication card, or when the first communication card of the terminal device is in an inactive state or an idle state and the second communication card of the terminal device is in a connected state, the terminal device sends an indication message to the second network, wherein the indication message is used to indicate the location update parameters that the second communication card expects or does not expect.

[0070] Step 202: The terminal device receives configuration information sent by the second network, where the configuration information is used to determine location update parameters configured by the second network for the second communication card; wherein the location update parameters configured by the second network for the second communication card are determined based on the indication information.

[0071] In the embodiment of the present application, 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. Figure 3 On the one hand, the terminal device can access the first network through the first communication card to implement services on the first network. On the other hand, the terminal device can access the second network through the second communication card to implement 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.

[0072] 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 first network through the USIM-A card, and the terminal device can communicate with the second network through the USIM-B card.

[0073] In the embodiment of the present application, the communication card performs different periodic location updates in different RRC states. For example, the periodic location update of the communication card in the idle state includes the CN periodic location update. The periodic location update of the communication card in the inactive state includes the RAN surrounding location update and the CN periodic location update.

[0074] It should be noted that the RAN peripheral location update can also be called the RAN notification area (RAN Notification Area, RNA) update, which is maintained by the access network. The CN periodic location update can also be called the tracking area (Tracking Area, TA) update, which is maintained by the core network.

[0075] Since the first communication card and the second communication card share the transmission resources of the terminal device, the first communication card and the second communication card cannot perform periodic location updates at the same time, and it is necessary to avoid periodic location updates of the first communication card and the second communication card. To this end, in the case where the periodic location updates of the first communication card of the terminal device conflict with the periodic location updates of the second communication card, or the first communication card of the terminal device is in an inactive state or an idle state and the second communication card of the terminal device is in a connected state, the terminal device sends indication information to the second network, and the indication information is used to indicate the expected location update parameters or the unexpected location update parameters of the second communication card, so that the second network can determine the location update parameters configured for the second communication card according to the indication information, and send the location update parameters configured for the second communication card to the terminal device through the configuration information. Here, the terminal device sends the indication information to the second network through the second communication card in the connected state.

[0076] It should be noted that the indication information sent by the terminal device to the second network may also be referred to as auxiliary information, and the auxiliary information is used to assist the second network in configuring location update parameters for the second communication card.

[0077] In the embodiment of the present application, the location update parameter includes periodic information and / or trigger time information related to periodic location update.

[0078] Here, taking the implementation of periodic location update based on a timer as an example, the start time of the timer is the trigger time related to the periodic location update, the duration of the timer is the period related to the periodic location update, and if the timer times out, the periodic location update is triggered. Here, the triggering of the periodic location update can be that the communication card sends a location update request message to the corresponding network.

[0079] The following describes how to avoid periodic location update conflicts between two communication cards in combination with periodic location update types of two communication cards in different RRC states.

[0080] ●Situation 1

[0081] The periodic location update of the first communication card in the idle state includes a first CN periodic location update, and the periodic location update of the second communication card in the idle state includes a second CN periodic location update.

[0082] When the first communication card is in an idle state and the second communication card is in a connected state, the terminal device sends a first NAS message to the core network of the second network, and the first NAS message carries indication information, and the indication information is used to indicate the CN location update parameters expected by the second communication card or the CN location update parameters that are not expected; wherein the indication information is also used by the core network of the second network to determine the CN location update parameters of the second communication card, wherein the CN location update parameters of the second communication card are used to ensure that the second CN periodic location update does not conflict with the first CN periodic location update.

[0083] In an optional embodiment, the core network of the second network includes AMF.

[0084] In one example, the USIM-A card of the terminal device is in an idle state, and the USIM-B card is in a connected state. The terminal device sends a first NAS message to the second network through the USIM-B card. The first NAS message carries indication information, and the indication information is used to indicate to the AMF the expected CN location update parameters or the unexpected CN location update parameters after the second communication card enters the idle state. The AMF configures the CN location update parameters for the second communication card based on the indication information. Here, the CN location update parameters configured for the second communication card are used to ensure that the second CN periodic location update of the second communication card does not conflict with the first CN periodic location update of the first communication card. Further, optionally, the AMF determines whether to update the CN location update parameters of the second communication card based on the indication information. If updated, the AMF sends a second NAS message to the terminal device, and the second NAS message carries the updated CN location update parameters of the second communication card.

[0085] It should be noted that the periodic location updates of the two communication cards do not conflict with each other means that the time periods of the periodic location updates of the two communication cards do not have an overlapping area.

[0086] ●Situation 2

[0087] The periodic location update of the first communication card in the inactive state includes a first RAN periodic location update and a first CN periodic location update, and the periodic location update of the second communication card in the idle state includes a second CN periodic location update.

[0088] When the first communication card is in an inactive state and the second communication card is in a connected state, the terminal device sends a first NAS message to the core network of the second network, and the first NAS message carries indication information, and the indication information is used to indicate the CN location update parameters expected by the second communication card or the CN location update parameters not expected by the second communication card; wherein the indication information is also used by the core network of the second network to determine the CN location update parameters of the second communication card, wherein the CN location update parameters of the second communication card are used to ensure that the second CN periodic location update does not conflict with the first RAN periodic location update and the first CN periodic location update.

[0089] In an optional embodiment, the core network of the second network includes AMF.

[0090] In one example, the USIM-A card of the terminal device is in an inactive state, and the USIM-B card is in a connected state. The terminal device sends a first NAS message to the second network through the USIM-B card. The first NAS message carries indication information, and the indication information is used to indicate to the AMF the expected CN location update parameters or the unexpected CN location update parameters after the second communication card enters the idle state. The AMF configures the CN location update parameters for the second communication card based on the indication information. Here, the CN location update parameters configured for the second communication card are used to ensure that the second CN periodic location update of the second communication card does not conflict with the first RAN periodic location update and the first CN periodic location update of the first communication card. Further, optionally, the AMF determines whether to update the CN location update parameters of the second communication card based on the indication information. If updated, the AMF sends a second NAS message to the terminal device, and the second NAS message carries the updated CN location update parameters of the second communication card.

[0091] It should be noted that the periodic location updates of the two communication cards do not conflict with each other means that the time periods of the periodic location updates of the two communication cards do not have an overlapping area.

[0092] ●Situation 3

[0093] The periodic location update of the first communication card in the idle state includes a first CN periodic location update, and the periodic location update of the second communication card in the inactive state includes a second RAN periodic location update and a second CN periodic location update.

[0094] When the first communication card is in an idle state and the second communication card is in a connected state, the terminal device sends a first RRC message to the access network of the second network and sends a first NAS message to the core network of the second network, the first RRC message carries first indication information, and the first NAS message carries second indication information, the first indication information is used to indicate the RAN location update parameter expected by the second communication card or the RAN location update parameter not expected, and the second indication information is used to indicate the CN location update parameter expected by the second communication card or the CN location update parameter not expected; wherein the first indication information is also used by the access network of the second network to determine the RAN location update parameter of the second communication card, wherein the RAN location update parameter of the second communication card is used to ensure that the second RAN periodic location update does not conflict with the first CN periodic location update; the second indication information is also used by the core network of the second network to determine the CN location update parameter of the second communication card, wherein the CN location update parameter of the second communication card is used to ensure that the second CN periodic location update does not conflict with the first CN periodic location update.

[0095] In an optional manner, the access network of the second network includes a base station (such as a gNB), and the core network of the second network includes an AMF.

[0096] In one example, the USIM-A card of the terminal device is in an idle state, and the USIM-B card is in a connected state. The terminal device sends a first RRC message and a first NAS message to the second network through the USIM-B card. The first RRC message carries first indication information, and the first indication information is used to indicate to the base station the RAN location update parameters expected by the second communication card or the RAN location update parameters that are not expected. The first NAS message carries second indication information, and the second indication information is used to indicate to the AMF the CN location update parameters expected by the second communication card or the CN location update parameters that are not expected. The base station configures the RAN location update parameters for the second communication card based on the first indication information. Here, the RAN location update parameters configured for the second communication card are used to ensure that the second RAN periodic location update of the second communication card does not conflict with the first CN periodic location update of the first communication card. The AMF configures the CN location update parameters for the second communication card based on the second indication information. Here, the CN location update parameters configured for the second communication card are used to ensure that the second CN periodic location update of the second communication card does not conflict with the first CN periodic location update of the first communication card.

[0097] It should be noted that the periodic location updates of the two communication cards do not conflict with each other means that the time periods of the periodic location updates of the two communication cards do not have an overlapping area.

[0098] ●Situation 4

[0099] The periodic location update of the first communication card in the inactive state includes a first RAN periodic location update and a first CN periodic location update, and the periodic location update of the second communication card in the inactive state includes a second RAN periodic location update and a second CN periodic location update.

[0100] When the first communication card is in an inactive state and the second communication card is in a connected state, the terminal device sends a first RRC message to the access network of the second network and sends a first NAS message to the core network of the second network, the first RRC message carries first indication information, the first NAS message carries second indication information, the first indication information is used to indicate the RAN location update parameter expected by the second communication card or the RAN location update parameter not expected, and the second indication information is used to indicate the CN location update parameter expected by the second communication card or the CN location update parameter not expected; wherein the first indication information is also used by the access network of the second network to determine the RAN location update parameter of the second communication card, wherein the RAN location update parameter of the second communication card is used to ensure that the second RAN periodic location update does not conflict with the first RAN periodic location update and the first CN periodic location update; the second indication information is also used by the core network of the second network to determine the CN location update parameter of the second communication card, wherein the CN location update parameter of the second communication card is used to ensure that the second CN periodic location update does not conflict with the first RAN periodic location update and the first CN periodic location update.

[0101] In an optional manner, the access network of the second network includes a base station (such as a gNB), and the core network of the second network includes an AMF.

[0102] In one example, the USIM-A card of the terminal device is in an inactive state, and the USIM-B card is in a connected state. The terminal device sends a first RRC message and a first NAS message to the second network through the USIM-B card. The first RRC message carries first indication information, and the first indication information is used to indicate to the base station the RAN location update parameters expected by the second communication card or the RAN location update parameters that are not expected. The first NAS message carries second indication information, and the second indication information is used to indicate to the AMF the CN location update parameters expected by the second communication card or the CN location update parameters that are not expected. The base station configures the RAN location update parameters for the second communication card based on the first indication information. Here, the RAN location update parameters configured for the second communication card are used to ensure that the second RAN periodic location update of the second communication card does not conflict with the first RAN periodic location update and the first CN periodic location update of the first communication card. The AMF configures the CN location update parameters for the second communication card based on the second indication information. Here, the CN location update parameters configured for the second communication card are used to ensure that the second CN periodic location update of the second communication card does not conflict with the first RAN periodic location update and the first CN periodic location update of the first communication card.

[0103] It should be noted that the periodic location updates of the two communication cards do not conflict with each other means that the time periods of the periodic location updates of the two communication cards do not have an overlapping area.

[0104] The technical solution of the embodiment of the present application can provide auxiliary information (i.e., indication information) to the network when the periodic location update of the first communication card not detected by the terminal device conflicts with the periodic location update of the second communication card, so that the network can configure appropriate location update parameters according to the auxiliary information to avoid conflicts between the periodic location updates of the two communication cards, thereby achieving the purpose of preventing conflicts. Alternatively, in the case where the periodic location update of the first communication card detected by the terminal device conflicts with the periodic location update of the second communication card, auxiliary information (i.e., indication information) can be provided to the network, so that the network can configure appropriate location update parameters according to the auxiliary information to avoid conflicts between the periodic location updates of the two communication cards.

[0105] Figure 4 This is a flow chart of the location update method provided in the embodiment of the present application. Figure 2 ,like Figure 4 As shown, the location updating method comprises the following steps:

[0106] Step 401: The terminal device determines that a periodic location update of the first communication card and a periodic location update of the second communication card conflict based on a location update parameter of the first communication card and a location update parameter of the second communication card.

[0107] In the embodiment of the present application, 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. Figure 3 On the one hand, the terminal device can access the first network through the first communication card to implement services on the first network. On the other hand, the terminal device can access the second network through the second communication card to implement 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.

[0108] 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 first network through the USIM-A card, and the terminal device can communicate with the second network through the USIM-B card.

[0109] In the embodiment of the present application, the communication card performs different periodic location updates in different RRC states. For example, the periodic location update of the communication card in the idle state includes the CN periodic location update. The periodic location update of the communication card in the inactive state includes the RAN surrounding location update and the CN periodic location update.

[0110] Since the first communication card and the second communication card share the transmission resources of the terminal device, the first communication card and the second communication card cannot perform periodic location update at the same time, and it is necessary to avoid periodic location update conflicts between the first communication card and the second communication card. To this end, in the case where the periodic location update of the first communication card of the terminal device conflicts with the periodic location update of the second communication card, the terminal device initiates the periodic location update of the first communication card a certain time in advance, and initiates the periodic location update of the second communication card according to the location update parameters of the second communication card.

[0111] In the embodiment of the present application, the location update parameter includes periodic information and / or trigger time information related to periodic location update.

[0112] Here, taking the implementation of periodic location update based on a timer as an example, the start time of the timer is the trigger time related to the periodic location update, the duration of the timer is the period related to the periodic location update, and if the timer times out, the periodic location update is triggered. Here, the triggering of the periodic location update can be that the communication card sends a location update request message to the corresponding network.

[0113] In an embodiment of the present application, the location update parameter of the first communication card can determine the location update time of the first communication card, and the location update parameter of the second communication card can determine the location update time of the second communication card. The terminal device can determine whether the periodic location update of the first communication card and the periodic location update of the second communication card will conflict based on the location update parameters of the first communication card and the location update parameters of the second communication card.

[0114] It should be noted that the periodic location update conflict of two communication cards means that the time periods of the periodic location updates of the two communication cards have an overlapping area.

[0115] Step 402: The terminal device initiates a periodic location update of the first communication card a certain time in advance relative to a first time, and initiates a periodic location update of the second communication card according to a location update parameter of the second communication card, wherein the first time is determined based on the location update parameter of the first communication card.

[0116] In the embodiment of the present application, the terminal device initiates a periodic location update of the first communication card a certain time in advance, and initiates a periodic location update of the second communication card according to the location update parameter of the second communication card.

[0117] It should be noted that the following descriptions of the first communication card and the second communication card can also be reversed, for example: the terminal device initiates the periodic location update of the second communication card a certain time in advance, and initiates the periodic location update of the first communication card according to the location update parameters of the first communication card. The main purpose is to stagger the periodic location update times of the two communication cards, thereby avoiding conflicts between the periodic location updates of the two communication cards.

[0118] The following describes how to avoid periodic location update conflicts between two communication cards in combination with periodic location update types of two communication cards in different RRC states.

[0119] ●Situation A

[0120] The periodic location update of the first communication card in the idle state includes a first CN periodic location update, and the periodic location update of the second communication card in the idle state includes a second CN periodic location update.

[0121] The terminal device initiates a first CN periodic location update of the first communication card a certain time in advance relative to the first time, and initiates a second CN periodic location update according to a location update parameter of the second communication card.

[0122] ●Situation B

[0123] The periodic location update of the first communication card in the inactive state includes a first RAN periodic location update and a first CN periodic location update, and the periodic location update of the second communication card in the idle state includes a second CN periodic location update.

[0124] The terminal device initiates the first RAN periodic location update and the first CN periodic location update a certain time in advance relative to the first time, and initiates the second CN periodic location update according to the location update parameters of the second communication card.

[0125] ●Situation C

[0126] The periodic location update of the first communication card in the idle state includes a first CN periodic location update, and the periodic location update of the second communication card in the inactive state includes a second RAN periodic location update and a second CN periodic location update.

[0127] The terminal device initiates the first CN periodic location update a certain time in advance relative to the first time, and initiates the second RAN periodic location update and the second CN periodic location update according to the location update parameter of the second communication card.

[0128] ●Situation D

[0129] The periodic location update of the first communication card in the inactive state includes a first RAN periodic location update and a first CN periodic location update, and the periodic location update of the second communication card in the inactive state includes a second RAN periodic location update and a second CN periodic location update.

[0130] The terminal device initiates the first RAN periodic location update and the first CN periodic location update a certain time in advance relative to the first time, and initiates the second RAN periodic location update and the second CN periodic location update according to the location update parameter of the second communication card.

[0131] In an embodiment of the present application, when a conflict occurs between the periodic location update of the first communication card and the periodic location update of the second communication card, a request may be made to the network side to modify the location update parameters of the first communication card or the second communication card, so as to stagger the periodic location update times of the two communication cards, thereby avoiding a conflict between the periodic location updates of the two communication cards. Further, optionally, taking the modification of the location update parameters of the second communication card as an example, the terminal device may send an indication message to the second network, wherein the indication message is used to indicate the expected location update parameters or the unexpected location update parameters of the second communication card, so that the second network can configure appropriate location update parameters for the second communication card, thereby achieving the purpose of staggering the periodic location update times of the two communication cards. Here, the indication message scheme may be combined with the aforementioned Figure 2 The scheme shown.
