[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0066] The term "comprise" and any variation thereof in the specification and claims of the present application are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. In addition, the use of "and / or" in the specification and claims to indicate at least one of the connected objects, such as A and / or B, means that A alone, B alone, and A and B exist in three cases.

[0067] The embodiments of the present application are introduced below in conjunction with the accompanying drawings. The connection control method, device and communication equipment provided in the embodiments of the present application are not limited to the Long Term Evolution (LTE) / LTE evolution (LTE-Advanced, LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described techniques can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following descriptions, although these techniques can also be applied to applications other than NR system applications, such as the 6th generation (6 th Generation, 6G) communication system.

[0068] In order to facilitate a better understanding of the embodiments of the present application, the following technical points are first introduced below.

[0069] A multi-card terminal is a device with two or more than two User Identity Module (SIM) cards. The SIM card is an electronic SIM card or a physical SIM card. From the perspective of the network, the same terminal device and different SIM cards constitute different UEs.

[0070] Optionally, the SIM cards in the multi-card terminal may belong to the same operator or different operators. The wireless communication networks accessed by different SIM cards may be the same or different.

[0071] Optionally, the SIM card may include one of the following: a SIM card, a Universal Subscriber Identity Module (USIM) card, or an Embedded-SIM (eSIM) card. The SIM card may also be named in other ways, such as directly called a "card", which is not limited in this application.

[0072] For dual-card or multi-card terminals, the terminal's capabilities may not be able to support the simultaneous sending and receiving of service data of the networks corresponding to the two cards. When the terminal abandons the service data of card A and switches to the service data of card B. The terminal can notify the network of card A of the terminal's departure to save unnecessary network resource overhead. The network of card A may choose to release or suspend the terminal's connection with the network of card A based on the policy, and notify the terminal through a connection release command or a connection suspension command. However, the stay on card A waiting for network signaling may delay the terminal from listening to the service on card B (such as voice service). At this time, the terminal may not be able to wait for the network to send a connection release or connection suspension command. If the terminal is always released locally, the terminal needs to initiate a connection establishment process when it returns to the network of card A after the service of card B is completed. The connection establishment process is longer than the process of connection suspension and then connection recovery, and the terminal does not use the terminal to quickly switch between the networks of the two cards.

[0073] Therefore, the following issues need to be addressed

[0074] Question 1: How to support local terminal suspension? That is, when the terminal initiates to leave the network, it can suspend the connection with the network locally without waiting for the connection suspension command and connection suspension configuration sent by the network.

[0075] Problem 2: When the terminal notifies the network that the terminal is leaving, the network does not know that the terminal intends to leave locally, and the network will send a connection release command or a connection suspension command to the terminal. Obviously, these signaling overheads are a waste of resources, so it is necessary to solve the problem of resource waste such as the network sending a connection release command or a connection suspension command (such as RRC release signaling).

[0076] For problem 1, one solution is that the terminal negotiates with the network in advance whether to perform local release or local suspension when leaving the local area; when it is confirmed to be local suspension, the network sends the connection suspension configuration information to the terminal in advance. The connection suspension configuration information takes effect when the connection is suspended.

[0077] For problem 2, one solution is that when the terminal leaves the network, it clearly indicates that the departure is a local departure or sends a local departure waiting time.

[0128] In one implementation, the terminal accessing the idle state may be the terminal entering the RRC idle state or the connection management idle state.

[0129] In one implementation, the paging response operation may be a terminal responding to network paging.

[0130] Optionally, the operation of locally suspending the connection with the first network includes at least one of the following:

[0131] In the case of not receiving a connection suspension command, a connection release command and / or connection suspension configuration information sent by the first network, locally suspending the connection between the terminal and the first network;

[0132] The terminal enters an inactive state;

[0133] Execute a connection recovery operation according to the configuration information of the connection suspension;

[0134] Paging response operation.

[0135] In one implementation, the above-mentioned local suspension of the connection between the terminal and the first network without receiving a connection suspension command, a connection release command and / or the configuration information of the connection suspension sent by the first network may be that the local suspension of the connection between the terminal and the first network without receiving at least one of the connection suspension command, the connection release command and the configuration information of the connection suspension. For example: the terminal locally suspends the connection between the terminal and the first network without receiving a connection suspension command, a connection release command and / or the configuration information of the connection suspension.

[0136] In one implementation, the connection suspension command is embodied by a connection release command carrying the connection suspension configuration information. The connection release command is, for example, an RRC connection release command.

[0137] In one implementation, the terminal entering the inactive state may be the terminal entering the RRC inactive state and the connection management connected state. The paging response operation in the RRC inactive state is a paging response operation to RAN paging.

[0138] In one implementation, the above-mentioned operation of performing connection recovery according to the configuration information of the connection suspension may be to perform the operation of connection recovery through information such as the terminal identifier (resume ID) in the configuration information. The operation of performing connection recovery may be that the terminal requests the first network to restore the connection between the terminal and the first network.

[0139] In one implementation, the paging response operation may be a response operation of the terminal to the paging of the first network.

[0140] Optionally, before the step of obtaining the second information, the method further includes:

[0141] The first information is sent, where the first information is used to negotiate a local leave mode, to indicate a local leave mode preferred by the terminal, and / or to request a local leave configuration.

[0142] Optionally, the first information includes the local leaving mode that the terminal prefers, such as the terminal prefers to locally release the connection with the network when leaving the network, or the terminal prefers to locally suspend the connection with the network when leaving the network.

[0143] In one implementation, the first information is sent to the first network. For example, the first information is sent to a radio access network element or a core network element of the first network.

[0144] In one implementation, the second information is obtained from the first network. For example, the second information may be second information determined by the first network based on the first information and returned to the first communication device.

[0145] In one implementation, the first information may be sent to the first network via an RRC message or a NAS message.

[0146] In one implementation, the first information may be used to negotiate with the network side on a local leaving method.

[0147] Optionally, the second information also includes: paging-related configuration information, wherein the paging-related configuration information includes: a maximum time interval from receiving a paging to a paging response.

[0148] In one implementation, the terminal may perform a paging response operation according to the maximum time interval. It is not difficult to understand that according to the maximum time interval from paging to paging response, the terminal may delay the paging response as long as it is ensured not to exceed the maximum time interval.

[0149] In one implementation, the second information includes: local leave operation information and configuration information of connection suspension; and the local leave operation information indicates local suspension.

[0150] In one implementation, the second information includes: local leaving operation information, and paging related configuration information; and the local leaving operation information indicates local release.

[0151] In one implementation, the second information includes: local leaving operation information, connection suspension configuration information, and paging related configuration information; and the local leaving operation information indicates local suspension.

[0152] Optionally, the step of performing, according to the second information, a local operation of releasing the connection with the first network or a local operation of suspending the connection with the first network includes:

[0153] In case the second information includes a maximum time interval from receiving a paging call to a paging response, a paging response operation is performed, wherein the paging response operation includes: delaying a paging response after receiving a paging call, and the paging response time does not exceed the maximum time interval from receiving a paging call to a paging response.

[0154] In one implementation, the delayed paging response after receiving the paging may be that after the terminal receives the paging sent by the network side, it delays responding to the paging, wherein the paging response time does not exceed the maximum time interval from receiving the paging to the paging response.

[0155] Optionally, the step of performing, according to the second information, a local operation of releasing the connection with the first network or a local operation of suspending the connection with the first network includes:

[0156] When it is confirmed that the condition for leaving the first network locally is met, performing, according to the second information, operations related to releasing the local connection with the first network or operations related to suspending the local connection with the first network;

[0157] The condition for satisfying the local leaving the first network includes at least one of the following:

[0158] Initiate a terminal leaving process to the first network or send first indication information to the first network, the first indication information is used to indicate at least one of the following: terminal leaving, terminal leaving locally, terminal requesting to leave, terminal requesting to leave locally, terminal requesting to release the connection with the network, terminal requesting to suspend the connection with the network, terminal requesting to release the connection with the network locally, and terminal requesting to suspend the connection with the network locally;

[0159] Determine to leave the first network;

[0160] Cannot wait to receive the signaling of connection release or connection suspension sent by the first network to the terminal.

[0161] In one implementation manner, the local terminal leaving means that the local terminal releases the connection between the terminal and the first network without receiving a connection release command sent by the first network.

[0162] In one implementation, the above-mentioned inability to wait for receiving the connection release or connection suspension signaling sent by the first network to the terminal may be that the waiting time for the terminal to execute the connection release or connection suspension is less than a preset threshold, such as equal to time 0, or less than the time for the network side to send a release or recovery signaling to the terminal.

[0163] In one implementation, for dual-SIM UE, when the UE resides on the network of SIM 1, the user may switch to the network of SIM 2 to receive service data (such as a phone call), and the UE may notify the network of SIM 1 of the terminal's departure. When the service latency requirement of SIM 2 is high, it cannot wait for the network of SIM 1 to send a release or suspension command to the UE. Therefore, the UE may release or suspend locally after notifying the network.

[0164] Optionally, the step of performing, according to the second information, a local operation of releasing the connection to the first network or a local operation of suspending the connection to the first network includes at least one of the following:

[0165] When the second information includes local leaving mode indication information and the local leaving mode indication information indicates local release of the connection with the network, performing operations related to local release of the connection with the first network;

[0166] In the case where the second information includes connection suspension configuration information and / or local leaving mode indication information, and the local leaving mode indication information indicates that the local connection with the network is suspended, operations related to the local connection with the first network are performed.

[0167] In one implementation, the second information includes configuration information for suspending the connection, and performing operations related to suspending the local connection with the first network;

[0168] In one implementation, the connection can be suspended locally according to the configuration information of the connection suspension, for example, when the connection with the first network needs to be restored, the connection is restored.

[0169] In an embodiment of the present application, second information is obtained, and the second information includes at least one of the following: local leaving mode indication information, and connection suspension configuration information. According to the second information, a local release operation related to the first network connection is performed or a local suspension operation related to the first network connection is performed; wherein the local leaving mode indication information is used to indicate that the local leaving mode is to locally release the network connection, or the local leaving mode indication information is used to indicate that the local leaving mode is to locally suspend the network connection.

[0170] In this way, local release operations related to the connection with the first network or local suspension operations related to the connection with the first network are performed based on the obtained second information. On the one hand, it can support the terminal to quickly return to the first network after leaving the first network, and on the other hand, it can also save signaling of the first network.

[0199] Alternatively, determining a maximum time interval from receiving a paging call to receiving a paging response according to the third information;

[0200] in,

[0201] The waiting time for the terminal to leave locally is the time for the terminal to wait for the relevant signaling of connection release or connection suspension sent by the network after initiating a leave request to the network. When the relevant signaling of connection release or connection suspension is not received after the time is exceeded, the terminal executes local release or local suspension of the connection with the network;

The local release of the connection with the terminal may be to suspend the connection with the terminal without sending a connection release signaling to the terminal. In one implementation, locally suspending the connection with the terminal may refer to locally suspending the connection with the terminal when the terminal leaves. The local suspension of the connection with the terminal may be to suspend the connection with the terminal without sending a connection suspension signaling to the terminal.

[0205] In one implementation manner, the obtaining of the third information may be obtaining the third indication information from a core network element, or may be obtaining the third information from a terminal.

[0206] In one implementation, the waiting time for the terminal to leave locally includes at least one of the following: the waiting time for the terminal to release locally, and the waiting time for the terminal to suspend locally.

[0207] In one implementation, the above-mentioned waiting time for the terminal to release locally and the waiting time for the terminal to suspend locally can be configured by the terminal itself, or agreed upon by the protocol, or configured in advance by the network side.

[0208] In one implementation, the waiting time for local release of the terminal is the time the terminal waits for network connection release related signaling after initiating a leave request or a release request to the network. When the time has expired and no connection release related signaling is received, the terminal performs local release related operations on the connection with the network.

[0209] In one implementation, the waiting time for the terminal to suspend locally is the time the terminal waits for network connection suspension related signaling after initiating a leave request or a suspend request to the network. When the time has expired and no connection suspension related signaling is received, the terminal performs local suspension related operations for the connection with the network.

[0216] In one implementation, the receiving of the first indication information may be receiving the first indication information sent by the terminal, or receiving the first indication information sent by the CN network element, or receiving the first indication information sent by the RAN network element. It is not difficult to understand that when the communication device is a RAN network element, the terminal sends the first indication information to the CN network element, and the CN network element may send the first indication information to the RAN network element.

[0217] Optionally, the step of performing, according to the second information or the third information, a local operation of releasing a connection with the terminal or a local operation of suspending a connection with the terminal comprises one of the following:

[0218] When the second information includes local leaving mode indication information and the local leaving mode indication information indicates local release of the connection with the network, performing operations related to local release of the connection with the terminal;

[0230] In one implementation, the terminal initiates a process of leaving the network to the CN network element, and the CN network element may send a command to locally release the connection with the terminal or send a command to locally suspend the connection with the terminal to the RAN network element according to the second information or the third information.

[0231] In one implementation, in the case where a connection release command is not sent, locally releasing the connection with the terminal may be directly locally releasing the connection with the terminal without sending a connection release command to the terminal.

[0232] In one implementation manner, the above method may also locally release the context of the terminal in the first network without sending a connection release command.

[0233] In one implementation, setting the terminal to an idle state may be setting the terminal to an RRC idle state or a connection management idle state.

[0234] In one embodiment, in the case where the connection suspension command, connection release command and / or connection suspension configuration information are not sent, the local suspension of the connection with the terminal may be to directly suspend the connection with the terminal locally without sending at least one of the connection suspension command, connection release command and connection suspension configuration information to the terminal. In one embodiment, the connection suspension command is reflected by carrying the connection suspension configuration in the connection release command.

[0235] In one implementation, setting the terminal to an inactive state may be setting the terminal to an RRC inactive state and a connection management connected state.

[0236] Optionally, according to the third information and when the network's operation instruction information when the terminal leaves indicates that the local connection is suspended, the configuration information of the connection suspension is determined. It is not difficult to understand that the terminal can send the first information to the CN network element to negotiate the local leaving method. The CN network element can only confirm the local leaving method and send it to the terminal and the RAN network element respectively through the second information and the third information. The RAN network element determines the configuration information of the connection suspension according to the third information and when the network's operation instruction information when the terminal leaves indicates that the local connection is suspended. And send the configuration information of the connection suspension to the terminal. The information in the first information is determined by the RAN network element and the CN respectively.

[0237] Optionally, after the step of determining the configuration information of the connection suspension, the configuration information of the connection suspension is sent, for example, the configuration information of the connection suspension is sent to the terminal.

[0238] Optionally, the maximum time interval from receiving a paging call to a paging response is determined according to the third information; it is not difficult to understand that the terminal can send the first information to the CN network element to negotiate a local leaving method. The CN network element can only confirm the local leaving method and send it to the terminal and the RAN network element through the second information and the third information respectively. The RAN network element determines the maximum time interval from receiving a paging call to a paging response according to the third information. And sends the maximum time interval from receiving a paging call to a paging response to the terminal. It is equivalent to that the information in the first information is determined by the RAN network element and the CN respectively.

[0239] Optionally, after determining the maximum time interval from receiving a paging call to receiving a paging response, the maximum time interval from receiving a paging call to receiving a paging response is sent, for example, to the maximum time interval from receiving a paging call to receiving a paging response.

[0240] Through this embodiment, the second information or the third information can be obtained; according to the second information or the third information, the operation related to the local release of the connection with the terminal or the operation of the local suspension of the connection with the terminal is performed; or, when it is confirmed that the waiting time for the local departure of the terminal is zero or shorter than the time for sending the relevant signaling of the connection release or connection suspension, the operation related to the local release of the connection with the terminal or the operation of the local suspension of the connection with the terminal is performed; or, according to the third information and when the operation indication information of the network at the time of the terminal leaving indicates the local suspension of the connection with the terminal, the configuration information of the connection suspension is determined; or, according to the third information, the maximum time interval from receiving the paging to the paging response is determined. On the one hand, it can support the terminal to quickly return to the first network after leaving the first network, and on the other hand, it can also save the signaling of the first network.

[0241] See also Figure 5 , Figure 5 Another connection control method provided by an embodiment of the present invention is applied to a fourth communication device, the fourth communication device including but not limited to one of the following: a terminal, a core network element, a wireless access network element, such as Figure 5 As shown, the following steps are included:

[0242] Step 501, setting the terminal local departure waiting time to zero;

[0243] Step 502: Send the terminal local departure waiting time.

[0244] In one implementation, the waiting time for the terminal to leave locally includes at least one of the following: the waiting time for the terminal to release locally, and the waiting time for the terminal to suspend locally.

[0245] In one implementation, the above-mentioned waiting time for the terminal to release locally and the waiting time for the terminal to suspend locally can be configured by the terminal itself, or agreed upon by the protocol, or configured in advance by the network side.

[0246] In one implementation manner, sending the terminal local departure waiting time may be sending the terminal local departure waiting time to a CN network element or a RAN network element.

[0247] Optionally, the step of setting the terminal local departure waiting time to zero includes: when it is confirmed that the condition for the terminal to leave locally immediately is met, setting the terminal local departure waiting time to zero.

[0248] In one implementation, the above-mentioned condition for satisfying the terminal's immediate local departure may be configured by the terminal itself, agreed upon by a protocol, or configured in advance by the network side.

[0249] In one implementation, the above-mentioned condition for satisfying the terminal's immediate local departure may include:

[0250] Service conflicts cause the terminal to leave the first network immediately. For example, the service of the first network conflicts with the service of the second network. The user believes that the service of the second network is more important and has a high latency requirement, so the terminal is required to handle it immediately. Therefore, the terminal needs to leave the local area immediately and cannot wait for the signaling of the first network.

[0251] In one embodiment, the waiting time for the terminal to leave locally is the time the terminal waits for the network to send a related signaling of connection release or connection suspension after initiating a leave request to the network. When this time is exceeded and no related signaling of connection release or connection suspension is received, the terminal executes local release or local suspension of the connection with the network.

[0252] Through this embodiment, the terminal local departure waiting time can be set to zero, and the terminal local departure waiting time can be sent. On the one hand, it can support the terminal to quickly return to the first network after leaving the first network, and on the other hand, it can also save the signaling of the first network, so as to improve the service performance of the communication device.

[0253] The connection control method provided in the embodiment of the present application is illustrated below by means of multiple embodiments:

[0254] Embodiment 1:

[0255] This embodiment can be seen in Figure 6 ,like Figure 6 As shown, the following steps are included:

[0256] Step 1: The UE sends an indication message to the RAN network element to indicate the release of the local connection. After the sending is completed, the UE releases the local connection.

[0257] Step 2: After receiving the indication information, the RAN network element sends a UE context release request to the CN network element (such as AMF or MME).

[0258] Step 3: The RAN network element receives the UE context release command sent by the CN network element

[0259] Step 4: According to the indication information and / or the UE context release command, the RAN network element locally releases the UE connection and / or the UE context in the RAN. The local release means that an RRC message such as an RRC release command is not sent to the UE.

[0260] Based on RAN implementation, step 4 may occur before step 3.

[0261] Embodiment 2:

[0262] This embodiment can be seen in Figure 7 ,like Figure 7 As shown, the following steps are included:

[0263] Step 1: The UE sends an indication message to the CN network element (such as AMF or MME) to indicate the release of the local connection. After the sending is completed, the UE releases the local connection.

[0264] Step 2: After receiving the indication information, the CN network element sends the indication information to the RAN network element. The CN network element may send a UE context release command to the RAN network element. The UE context release command includes the indication information.

[0265] According to the indication information and / or the UE context release command, the RAN network element locally releases the UE connection and / or the UE context in the RAN. The local release means not sending an RRC message such as an RRC release command to the UE.

[0266] Step 3: The RAN network element returns a message indicating that the UE context release is complete to the CN network element.

[0267] Through the above embodiments, when the UE needs to release locally, the network can also perform local release, thereby saving network signaling and air interface resources.

[0268] Embodiment 3:

[0269] This embodiment can be seen in Figure 8 ,like Figure 8 As shown, the following steps are included:

[0270] Step 1: UE sends first information (such as Figure 3 The embodiment), illustratively, may be included in a local leave negotiation request;

[0271] The RAN network element determines the second information and / or the third information according to the first information. Figure 3 The embodiments are described in detail and will not be repeated here.

[0272] In one implementation, the RAN stores the third information.

[0273] Step 2: The RAN network element sends the second information (such as Figure 2 As described in the embodiment, exemplarily, it may include a local leave negotiation response, which indicates a local release or indicates a local suspension, wherein when indicating a local suspension, it also includes configuration information of the connection suspension.

[0274] Step 3: The UE executes a local release procedure or a local suspension procedure.

[0275] Furthermore, the first information process may be stored in the UE context. The configuration of the second information may be different for different RAN network elements. After a handover between RAN network elements occurs, the UE does not need to repeatedly initiate the local leave negotiation request in step 1 to the target network element. The target RAN network element (Target RAN) can directly determine the second information according to the first information in the UE context decision, i.e., 2a / 2b.

[0276] Embodiment 4:

[0277] This embodiment can be seen in Fig. 9 ,like Fig. 9 As shown, the following steps are included:

[0278] Step 1: The UE sends first information (as described in Embodiment 2) to the CN network element, which may be included in a local leave negotiation request, for example;

[0279] The CN network element determines the second information and / or the third information according to the first information. Figure 3 The embodiments are described in detail and will not be repeated here.

[0280] Step 2: Optionally, the CN network element sends second information to the UE (as described in Embodiment 2), which may exemplarily be included in a local leave negotiation response, where the response indicates a local release or indicates a local suspension.

[0281] When indicating local suspension, configuration information of connection suspension is also included.

[0282] Step 3: The CN network element sends third information (network operation instruction information when the terminal leaves) to the RAN network element, where the third information instructs the local to release the connection with the terminal, or to suspend the connection with the terminal. The information may be sent via the N2 interface or other interfaces between the CN network element and the RAN network element.

[0283] The RAN network element can determine the configuration information of the connection suspension according to the third information and when the operation instruction information of the network when the terminal leaves indicates that the local connection with the terminal is suspended; specifically, Figure 4 As described in the embodiments.

[0284] Step 4: The CN network element sends the local leave mode indication information in the second information to the UE in step 2. When the local leave mode indicates local suspension, the RAN network element sends the connection suspension configuration information in the second information to the UE in step 4; or, the CN network element does not send any second information to the UE in step 2, but the RAN sends the complete second information to the UE.

[0285] Step 5: Subsequently, when the UE performs the local leaving process, the UE performs the local releasing process or the local suspending process according to the instruction of the second information, as shown in the following example: Figure 2 described.

[0286] The RAN network element or the CN network element may also perform a local release process or a local suspension process according to the third information or the second information, as shown in FIG. Figure 2 described.

[0287] In the embodiment of the present application, the following can be achieved:

[0288] The UE sends an indication message to the network, indicating a local release or waiting signaling time of zero. The network decides to release locally when the UE leaves based on the UE's information, and does not send a release signaling to the UE.

[0289] The UE negotiates with the network in advance, and the network confirms whether the UE local leaving is a local release or a local suspend, and configures the connection suspension configuration information. When the UE actually initiates the leaving, the UE enters the idle state or the inactive state (such as RRC inactive) according to the previous network's indication information indicating the UE local leaving.
