Embodiment 1

[0052] Such as figure 1 As shown, this embodiment provides a method for directional paging of a mobile terminal. The mobile terminal is a multi-card multi-standby mobile terminal, which has at least one 3G / 2G card and at least one 4G card. The method includes:

[0053] The mobile terminal obtains the identification message and sends it to the MSC, the identification message includes: the number of all cards in the mobile terminal, the IMSI of all cards;

[0054] The MSC creates a first association according to the identification message, and the first association is the association of the IMSIs of all cards in the mobile terminal;

[0055] When the 3G / 2G card is connected to the network, obtain the cell ID of the 4G card and send it to the MSC;

[0056] The MSC creates a second association, and the second association is the association between the IMSI of the 4G card and the cell identity of the 4G card;

[0057] When there is an incoming call to page the 4G card, after rece...

Embodiment 2

[0060] Such as figure 1 , 2 As shown, a method for directional paging of a mobile terminal is disclosed in this embodiment, wherein the mobile terminal is a dual-card dual-standby mobile terminal, and the mobile terminal has a 3G / 2G card and a 4G multi-mode card, and the 4G multi-mode card is selected CSFB technology enables voice calls, and 4G multi-mode cards and 3G / 2G cards belong to the same network operator. Since the existing 4G cards are all multi-mode cards, 4G multi-mode cards will be referred to as 4G cards hereinafter.

[0061] The method comprises the steps of:

[0062] Step 101, when the mobile terminal is turned on, first start the joint attachment process of the 4G card;

[0063] The joint attach process is specifically that the 4G card of the mobile terminal sends an Attach Request message to the MME, in which the parameter Attach Type indicates that this is a joint EPS / IMSI attach process, and the parameter indicates that the mobile terminal has the CSFallba...

Embodiment 3

[0096] A mobile terminal directional paging system, including a mobile terminal, the mobile terminal is a multi-card multi-standby mobile terminal, which has at least one 3G / 2G card and at least one 4G card, and also includes: the MME to which the MSC and the 4G card belong,

[0097] The mobile terminal is used to obtain the identification message and send it to the MSC. The identification message includes: the number of all cards in the mobile terminal and the IMSI of all cards;

[0098] The MSC is used to create a first association according to the identification message, and the first association is the association of the IMSIs of all cards in the mobile terminal;

[0099] The mobile terminal is also used to obtain the cell ID of the 4G card when the 3G / 2G card is connected to the network, and send the cell ID of the 4G card to the MSC;

[0100] The MSC is also used to create a second association, where the second association is the association between the IMSI of the 4G ca...

Abstract

The invention discloses a directional paging method for a mobile terminal. The mobile terminal is provided with at least one 3G / 2G card and at least one 4G card. The method comprises: the mobile terminal obtaining an identification message, the MSC creating a first association according to the identification message, when the 3G / 2G card is connected with a network, connecting the 3G card; acquiring and sending a cell identifier of a 4G card to an MSC, the MSC creating a second association, when an incoming call pages the 4G card, the MSC sending the cell identifier of the 4G card to an MME towhich the 4G card belongs according to the second association, and the MME sending a paging request to the 4G card according to the specific cell identifier of the 4G card. Correspondingly, the invention further discloses a directional paging system for a mobile terminal. According to the method and the system, directional paging can be realized, so that the problem that the MME pages all cells ofthe TAI of the 4G card in an idle state, and resources are wasted due to a large paging range is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for directional paging of a mobile terminal. Background technique [0002] Currently, dual-card dual-standby mobile terminals are relatively popular configurations. With the increasing demands of users in work and life, multi-card and multi-standby mobile terminals have emerged. Specifically, it means that more than two user cards can be inserted into a mobile terminal at the same time, and multiple user cards can be in the standby state at the same time. [0003] However, when the mobile terminal has at least one 3G / 2G card and at least one 4G card, and when the 4G card is attached to the LTE (Long Term Evolution, Long Term Evolution) network and is in an idle state, MME (Mobility Management Entity, network management The node) only knows the TAI (Tracking Area identity, tracking area identification) information of the 4G card. Since the TAI ...
