The techniques described herein may be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies.

In order to facilitate a better understanding of the embodiments of the present invention, the following technical points will be described.

A multi-card terminal is a device having two or more 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.

The capability of the multi-card terminal may be single-transmission double-reception, single-transmission single-reception, and double-transmission double-reception. For a terminal device with single transmission and single reception, the problem is the most because multiple UEs of the terminal device cannot work simultaneously. The main problems of single-shot include: (1) paging collision may exist between UE1 and UE2 on the same terminal device, and once paging collision occurs, it is impossible to listen to paging for one UE; (2) when the UE1 performs the voice service, since the voice service data interval is 20ms, there is no gap to listen to the page of the UE 2; (3) when both UE1 and UE2 are in a connected state, data about UE2 may be lost if the terminal device resides in a network on the UE1 side, and a call drop may occur if the data about UE2 is for voice called signaling.

For a single-transmitting and double-receiving terminal device, although there is no problem with paging, when pages are received for UE1 and UE2 at the same time, it is impossible to respond to both pages at the same time. When both UE1 and UE2 are in the connected state, the terminal device can only transmit data on one side.

For a dual-transmission and dual-reception terminal, although the UE1 and the UE2 can simultaneously transmit and receive data, the frequency band (band) configured for the UE1 and the UE2 by the network is required to belong to a band combination (band combination).

Therefore, in order to optimize the user experience of the multi-card terminal, the following problems are solved:

problem 1: paging collisions in the same operator. Or, if one side is in a connected state and performs voice, the other side is in an idle state, and the UE cannot monitor paging of the network on the other side. It is not clear how to resolve. For multi-card terminals of the same operator.

Problem 2: the multi-card optimization required for different terminal capabilities is different. But the network does not currently acknowledge the capabilities of the UE. Different terminals have different capabilities, such as single-transmission single-receiving, single-transmission double-receiving, double-transmission double-receiving, and the like. The dual-card problem that different capabilities need to be solved is different, and the network does not know the capability type of the multi-card terminal at present and needs to optimize in which aspect.

Problem 3: even if the terminal device has a plurality of card slots or has the capability of configuring a plurality of cards, a plurality of cards are not necessarily configured. The network does not know whether the terminal is a multi-card terminal or not and whether optimization is needed or not.

Referring to fig. 1, an architecture diagram of a wireless communication system according to an embodiment of the present invention is shown. As shown in fig. 1, a first UE and a second UE are configured on one device, and the second UE may be one or more UEs different from the first UE. The first UE is connected to the first RAN network element, a cell residing under the first RAN network element, or the first RAN network element stores a context of the first UE. The second UE is connected to the second RAN network element, a cell residing under the second RAN network element, or the second RAN network element stores the context of the second UE.

The first UE registers with a first Core Network (CN). The second UE registers with the second CN. The first CN and the second CN may be the same CN. The first UE registers with the first CN network element. The second UE registers with the second CN network element.
