Problems solved by technology

When there is an incoming call to page the 3G / 2G card, the MSC needs to page all the LAI cells of the 3G / 2G card. Due to the large paging range, the load on NodeB and wireless interface is increased, which wastes resources.

Embodiment 1

[0054] like figure 1 As shown, this embodiment provides a method for reducing the paging range of a mobile terminal. The mobile terminal has at least one 4G card and at least one 3G / 2G card. The method includes:

[0055] The mobile terminal obtains the identification message and sends it to the MME. The identification message includes: the number of all cards in the mobile terminal, and the IMSI of all cards;

[0056] The MME creates a first association, where the first association is the association of the IMSIs of all cards in the mobile terminal;

[0057] When the 4G card is connected to the network, the MME obtains the 3G / 2G network cell identity corresponding to the 4G network cell, and sends the 3G / 2G network cell identity and the IMSI of the 3G / 2G card obtained according to the first association to the MSC;

[0058] The MSC creates a second association, and the second association is the association between the IMSI of the 3G / 2G card and the cell identity of the 3G / 2G n...

Embodiment 2

[0061] like figure 1 , 2 As shown, a method for reducing the paging range of a mobile terminal is disclosed in this embodiment, wherein the mobile terminal is a dual-card dual-standby mobile terminal, that is, the mobile terminal has a 4G multi-mode card and a 3G / 2G card, and the 4G multi-mode The card selects CSFB technology to realize voice calls, and the 4G multi-mode card and the 3G / 2G card 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.

[0062] The method comprises the steps of:

[0063] Step 101, when the mobile terminal is turned on, first start the joint attachment process of the 4G card;

[0064] 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 termina...

Embodiment 3

[0090] A system for reducing the paging range of a mobile terminal, including a mobile terminal, the mobile terminal is a multi-card multi-standby mobile terminal, which has at least one 4G card and at least one 3G / 2G card, and also includes: MME and MSC,

[0091] The mobile terminal is used to obtain the identification message and send it to the MME. The identification message includes: the number of all cards in the mobile terminal and the IMSI of all cards;

[0092] The MME is used to create a first association, where the first association is the association of the IMSIs of all cards in the mobile terminal;

[0093] The MME is also used to obtain the 3G / 2G network cell identity corresponding to the 4G network cell according to the message of the 4G card connecting to the network, and to send the 3G / 2G network cell identity and the IMSI of the 3G / 2G card obtained according to the first association to the MSC;

[0094] The MSC is used to create a second association, and the ...

Abstract

The invention discloses a method for reducing the paging range of a mobile terminal, wherein the mobile terminal has at least one 4G card and at least one 3G / 2G card, the method comprises the steps of obtaining an identification message by the mobile terminal, MME creating a first association according to the identification message, and MME The configuration table is stored. When the 4G card is connected to the network, the MME obtains the corresponding 3G / 2G network cell ID, and sends the IMSI of the 3G / 2G card and the corresponding 3G / 2G network cell ID to the MSC, and the MSC creates a second association , when there is an incoming call to page the 3G / 2G card, the MSC sends the paging request to the corresponding 3G / 2G network cell according to the second association. Correspondingly, a system for narrowing the paging range of the mobile terminal is also disclosed. The method and system can reduce the paging range, thereby solving the problem that the MSC needs to perform paging to all cells of the LAI of the 3G / 2G card in an idle state, and the problem of wasting resources due to the large paging range.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for reducing the paging range 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 4G card and at least one 3G / 2G card, and when the 3G / 2G card is attached to the network and is idle, the MSC (Mobile Switching Center, Mobile Switching Center) only knows the 3G / 2G card. LAI (Location Area identity, location area identification) information of the 2G card, and the LAI includes multiple cells. When there is an incomin...
