Furthermore, the use of "and/or" in the specification and claims means at least one of the connected objects, e.g., a and/or B, meaning that it includes a single a, a single B, and that there are three cases of a and B.

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

Embodiments of the present application are described below with reference to the accompanying drawings. The control method, apparatus and communication device for leaving the network provided in the embodiments of the present application are not limited to the long term evolution (Long Term Evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) system, but may also be used in other wireless communication systems, such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), single carrier frequency division multiple access (Single-carrier Frequency-Division Multiple Access, SC-FDMA), and other systems. The terms "system" and "network" in embodiments of the present application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. However, the following description describes a New air interface (NR) system for purposes of example, and NR terminology is used in much of the following description, although these techniques are also applicable 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 described below.

A multi-card terminal is a subscriber identity module (SucrierIdetity Module, SIM) card with two or more than two on one device. The SIM card is an electronic SIM card or a physical SIM card. From the network point of view, the same terminal equipment and different SIM cards form different UEs.

Alternatively, 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.

Alternatively, the SIM card may comprise one of the following: SIM card, universal subscriber identity module (Universal Subscriber Identity Module, USIM) card, embedded SIM (eSIM) card. SIM cards may also be named otherwise, such as directly called "cards", without limitation.

For a dual-card or multi-card terminal, the capability of the terminal may not support the simultaneous transceiving of service data of the network corresponding to two cards. And when the terminal gives up the service data of the card A and switches 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 terminal and the card a network each release or suspend the UE's link with the network. However, when the terminal returns to the card a network, the terminal needs to establish or restore a connection with the card a network.

Therefore, there is a need to solve the following problems

Problem 1 when a terminal is to be switched from card a to card B, such as answering the phone of card B, the terminal leaves the first network (the network connected through card a). The terminal may request to release or suspend the terminal from 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 the card B, the user finds that the call of the card B is a nuisance call and may hang up immediately to return to the card a. At this time, the terminal needs to establish or restore a connection with the first network. The connection is established/restored after the connection is released/suspended in a short time, which results in redundant signaling overhead, is unfavorable for terminal energy saving, and also results in longer time delay for restoring data transmission between the terminal and the first network.

Problem 2, in one case, the terminal compares the importance of the card a and card B services, and considers the card B service more important and away from card a. But at the moment the terminal leaves the card a network, more important traffic data may come on the card a network, but the terminal is unaware and may miss the card a traffic.

One solution to problem 1 is that the terminal may negotiate a connection hold time with the first network (e.g., connection survival time). When the terminal requests to leave card a (the network connected through card a), the terminal and card a do not immediately release/suspend the terminal connection, but still keep the terminal and first network in a connected state, but suspend data transmission. If the terminal returns a leave revocation (revocation) indication before the connection hold time expires, the data transmission of the terminal with the first network is resumed. Otherwise, after the connection maintaining time is overtime, the first network and the terminal release or suspend the connection of the terminal. And the first network may not page the terminal for the connection hold time.

For problem 2, one solution is that the first network stops sending downlink data but can still send the service type information to which the downlink data belongs during the connection hold time when the terminal requests to leave the first network. Before the connection holding time is overtime, the terminal finds that the service on the card a is more important according to the service type information of the downlink data, and can request to withdraw from the first network.
