Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings 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. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The communication method, the communication device, and the electronic device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

In DSDS mode, when the dual cards are in state 2 (the main card (that is, the card where the data service is located) is in the data service connection state, and the secondary card is in the idle state), the following situations exist:

During the paging time slot of the secondary card, the primary card suspends the sending and receiving of data services and releases the radio frequency channel resources. The radio frequency channel resources are occupied by the secondary card to listen for paging;

When the tracking area of the secondary card changes, the tracking area update process needs to be performed; when the secondary card performs the tracking area update process, the radio frequency channel resources are occupied by the secondary card, and the data services of the main card are suspended until the secondary card process ends, and the radio frequency channel resources will be replaced by the primary card. The card is occupied for data services.

The secondary card IMS re-registration timer expires and needs to be re-registered. During the re-registration process of the secondary card, the RF channel resources are occupied by the secondary card, and the data service of the primary card is suspended until the secondary card process ends, and the RF channel resources are occupied by the primary card for data services.

It can be found that when the secondary card tracking area is updated or the IMS re-registration process is in progress, the data transmission service of the main card is suspended due to lack of radio frequency channel resources.

Therefore, please refer to FIG. 1 , which is a schematic flowchart of a communication method provided by an embodiment of the present application.
