For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to clear Instead, those steps or units listed below may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or equipment. In addition, the use of "and/or" in the specification and claims means at least one of the connected objects, such as A and/or B, which means that A and B alone are included, and there are three cases for both A and B.

In the embodiments of the present application, words such as "exemplary" or "for example" are used as examples, illustrations, or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferable or advantageous than other embodiments or design solutions. To be precise, words such as "exemplary" or "for example" are used to present related concepts in a specific manner.

The embodiments of the present application are described below in conjunction with the drawings. The method, device, and communication equipment for leaving the network provided by the embodiments of the application are not limited to the Long Term Evolution (LTE)/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 (Frequency Division Access, FDMA), Orthogonal Frequency Division Multiple Access (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 technology can be used for the aforementioned systems and radio technologies as well as other systems and radio technologies. However, the following description describes the New Radio (NR) system for illustrative purposes, and NR terminology is used in most of the description below, although these technologies can also be applied to applications other than NR system applications, such as the 6th generation ( 6th Generation, 6G) communication system.

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

A multi-card terminal is a device with two or more user identity module (Sucrier Idetity 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.

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.

Optionally, the SIM card may include one of the following: a SIM card, a Universal Subscriber Identity Module (USIM) card, and an embedded-SIM (Embedded-SIM, eSIM) card. The SIM card can also be used as another name, such as directly called "card", which is not restricted in this application.

For dual-card or multi-card terminals, the capabilities of the terminal may not support the simultaneous sending and receiving of service data of the networks corresponding to the two cards. When the terminal gives up the service data of card A and switches to the service data of card B. The terminal can notify the departure of the network terminal of card A to save unnecessary network resource overhead. The terminal and the card A network respectively release or suspend the link between the UE and the network. However, when the terminal returns to the card A network, the terminal needs to establish or restore the connection with the card A network.

Therefore, the following problems need to be solved

Question 1. When the terminal wants to leave card A and switch to card B, for example, when answering a phone call from card B, the terminal leaves the first network (the network connected through card A). The terminal can request to release or suspend the terminal and the first network. In one case, the terminal may quickly return to the first network after leaving the first network. For example, after the user answers the call of card B, and finds that the call of card B is a nuisance call, he may hang up and return to card A immediately. At this time, the terminal needs to establish or restore the connection with the first network. After the connection is released/suspended in a short period of time, the connection is established/resumed again, which results in redundant signaling overhead, which is not conducive to energy saving of the terminal, and the recovery of data transmission between the terminal and the first network also causes a long delay.

Question 2. In one case, the terminal compares the importance of the services of card A and card B, thinks that the service of card B is more important, and leaves card A. But at the moment when the terminal leaves the card A network, more important service data may come on the card A network, but the terminal does not know it, and thus may miss the card A service.

One solution to problem 1 is that the terminal can negotiate a connection retention time (for example: connection survival time) with the first network. When the terminal requests to leave the card A (the network connected through the card A), the terminal and the card A do not immediately release/suspend the terminal connection, and still keep the terminal in the connected state with the first network, but suspend the data transmission. If the terminal returns a revoking leaving instruction before the connection retention time expires, the data transmission between the terminal and the first network is resumed. Otherwise, after the connection retention time expires, the first network and the terminal release or suspend the connection of the terminal. In addition, the first network may not page the terminal within the connection maintaining time.

One solution to problem 2 is that, within the connection holding time when the terminal requests to leave the first network, the first network stops sending downlink data but can still send the service type information to which the downlink data belongs. Before the connection retention time expires, according to the service type information of the downlink data, the terminal finds that the service on the card A is more important, and can request the first network to withdraw and leave.
