All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "comprises," "comprising," or any other variation thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means that at least one of the connected objects, such as a and/or B, means that three cases, a alone, B alone, and both a and B, exist.

In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Embodiments of the present application are described below with reference to the accompanying drawings. The connection control method, apparatus, and communication device provided in the embodiments of the present application are not limited to Long Term Evolution (LTE)/LTE Evolution (LTE-Advanced) systems, and may 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 both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, although the techniques may also be applied to applications other than NR system applications, such as 6 th generation (6 th generation)^thGeneration, 6G) communication system.

In order to better understand the embodiments of the present application, the following technical points will be described.

A multi-card terminal is a device with two or more Subscriber Identity Module (SIM) cards. The SIM card is an electronic SIM card or a physical SIM card. From the network perspective, the same terminal device and different SIM cards form different UEs.

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 can be the same or different.

Optionally, the SIM card may include one of: SIM card, Universal Subscriber Identity Module (USIM) card, Embedded SIM (eSIM) card. The SIM card may also be named otherwise, such as directly "card," which is not intended to be limiting in this application.

For a dual-card or multi-card terminal, the capability of the terminal may not support simultaneous transceiving of service data of networks corresponding to two cards. And when the terminal gives up the service data of the card A to be switched to the service data of the card B. The terminal may notify the card a of the departure of the network terminal to save unnecessary network resource overhead. The card a's network may choose to release or suspend the terminal's connection to the card a network based on policy and inform the terminal through a connection release command or a connection suspend command. However, waiting for network signaling to remain at card a may delay the terminal listening to traffic (e.g., voice traffic) at card B. At this time, the terminal may not wait for the network to send a connection release or connection suspend command. If the terminal is always released locally, the terminal needs to initiate a connection establishment process when returning to the network of the card a after the service of the card B is finished. The connection establishment process is longer than the process of reconnection resumption after connection suspension, and it is not necessary to use a terminal to rapidly switch between networks of two cards.

Therefore, the following problems need to be solved

Problem 1, how to support local suspension of a terminal. I.e. when the terminal initiates a departure to the network, i.e. the connection to the network is suspended locally, without waiting for a connection suspend command and connection suspend configuration sent by the network.

Problem 2, when the terminal notifies the network of the departure of the terminal, the network does not know that the terminal's intention to leave is to leave locally, and the network sends a connection release command or a connection suspend 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 suspend command (e.g. RRC release signaling).

For the problem 1, one solution is that the terminal negotiates with the network in advance whether to perform local release or local suspension when locally leaving; when confirming that the connection is suspended locally, the network sends configuration information of the connection suspension to the terminal in advance. The configuration information of the connection suspension is in effect when the connection is suspended.

One solution to problem 2 is to explicitly indicate that the departure is a local departure or send a local departure wait time when the terminal leaves the network.

The connection control method provided by the embodiment of the present application is illustrated by a plurality of embodiments as follows:

example 1:

this embodiment can be seen in fig. 6, which is shown in fig. 6, comprising the steps of:

step 1: and the UE sends indication information to the RAN network element for indicating the release of the local connection. And after the sending is finished, the UE releases the local connection.

Step 2: and after receiving the indication information, the RAN network element sends a UE context release request to a CN network element (such as an AMF or MME).

And step 3: RAN network element receives UE context release command sent by CN network element

And 4, step 4: and 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 refers to not sending an RRC message such as an RRC release command to the UE.

Step 4 may occur prior to step 3 based on the RAN implementation.

Example 2:

this embodiment can be seen in fig. 7, which is shown in fig. 7, comprising the steps of:

step 1: the UE sends indication information to a CN network element (such as AMF or MME) for indicating the local connection release. And after the sending is finished, the UE releases the local connection.

Step 2: and after the CN network element reaches the indication information, the indication information is sent to the RAN network element. The CN network element may send a UE context release order to the RAN network element. The UE context release command includes the indication information.

And 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 refers to not sending an RRC message such as an RRC release command to the UE.

And step 3: and the RAN network element returns the UE context release completion to the CN network element.

Through the embodiment, when the UE needs to be locally released, the network also can locally release, so that the signaling of the network is saved, and the resources of an air interface are saved.

Example 3:

this embodiment can be seen in fig. 8, which is shown in fig. 8, comprising the steps of:

step 1, the UE sends first information (as described in the embodiment of fig. 3) to the RAN network element, which may be included in the local leave negotiation request, for example;

and the RAN network element determines second information and/or third information according to the first information. As described in the embodiment of fig. 3, details are not repeated here.

In one embodiment, the RAN stores the third information.

Step 2, the RAN network element sends second information (as described in the embodiment of fig. 2) to the UE, which may, for example, be included in a local leave negotiation response, where the response indicates local release or indicates local suspension, and when indicating local suspension, the RAN network element further includes configuration information of connection suspension.

And 3, the UE executes a local release process or a local suspension process.

Further, the first information procedure described above may be saved in the UE context. The configuration of the second information may be different decisions from the RAN network element. After the inter-RAN network element handover occurs, the UE may not repeatedly initiate the local leave negotiation request of step 1 to the Target network element, and the Target RAN network element (Target RAN) may directly determine the second information, i.e. 2a/2b, according to the first information in the UE context determination.

Example 4:

this embodiment can be seen in fig. 9, which is shown in fig. 9, comprising the steps of:

step 1, the UE sends first information (as described in embodiment 2) to the CN network element, which may be included in the local leave negotiation request, for example;

and the CN network element determines the second information and/or the third information according to the first information. As described in the embodiment of fig. 3, details are not repeated here.

Step 2, optionally, the CN network element sends second information (as described in embodiment 2) to the UE, which may, for example, include a local leave negotiation response, where the response indicates local release or indicates local suspension.

Wherein, when indicating the local hang, the method also comprises the configuration information of the connection hang.

Step 3, the CN network element sends third information (operation indication information of the network when the terminal leaves) to the RAN network element, where the third information indicates that the connection with the terminal is locally released or locally suspended, and the third information may be sent through an N2 interface or an interface between another CN network element and the RAN network element;

the RAN network element may determine, according to the third information and when the operation instruction information of the network when the terminal leaves indicates that the connection with the terminal is locally suspended, configuration information of the connection suspension; as described in the embodiment of fig. 4.

And step 4, the CN network element sends the local departure mode indication information in the second information to the UE in step 2. When the local leaving mode indicates local suspension, the RAN network element sends the configuration information of connection suspension in the second information to the UE in step 4; alternatively, 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.

Step 5, subsequently, when the UE executes the local leave procedure, the UE executes the local release procedure or the local suspend procedure according to the indication of the second information, which is specifically described in fig. 2.

The RAN network element or the CN network element may also perform a local release procedure or perform a local suspend procedure according to the third information or the second information, as specifically described in fig. 2.

In the embodiment of the application, the following can be realized:

and the UE sends indication information to the network to indicate that the local release or the waiting signaling time is zero. The network decides to release locally when the UE leaves according to the information of the UE, and does not send a release signaling to the UE.

The UE negotiates with the network in advance, the network confirms whether the UE local leaving (UE local leaving) is local releasing or local suspending (local suspend), and configures configuration information of the connection suspension. When the UE really initiates the leaving, the UE enters an idle state or an inactive state (such as RRCiactive) according to the indication information of the previous network indicating that the UE leaves locally.
