Problems solved by technology

[0043] There are dual-mode single-standby terminals in the existing network, and users can only stay on one network. Such terminals may frequently select networks due to network coverage, resulting in excessive power consumption. In addition, users cannot Selecting the network corresponding to the network capacity for business results in poor user experience. For 2G and 3G networks, 2G coverage is good, and 3G is still under construction and optimization. As a result, users still prefer to use 2G networks, resulting in 2G capacity saturation, while 3G idle resources

Embodiment 1

[0098] In this embodiment, the process of implementing the attachment of the dual-mode dual-standby terminal includes:

[0099] Step 1, when the dual-mode dual-standby terminal accesses the network, the attachment request sent to the core network device carries the indication information of the dual-mode dual-standby capability, and the IMSI or the P-TMSI corresponding to the IMSI;

[0100] The dual-mode dual-standby capability can be indicated by using the RevisionLevel field in the user category 2, for example, when the field is "11", it is used to identify that the terminal has dual-mode dual-standby capability.

[0101] Step 2: After receiving the attachment request, the core network device carries the IMSI of the terminal, the location information of the core network device and the access type information of this access in the location update request message sent to the subscription server;

[0102] Step 3: After receiving the location update request message, the subscrip...

Embodiment 2

[0150] This embodiment mainly relates to how a dual-mode dual-standby terminal that can use one International Mobile Subscriber Identity (IMSI) to access two wireless access networks selects a wireless access network for services according to service type or signal quality.

[0151] When the dual-mode dual-standby terminal implements the PDP context activation process, select a radio access network from the first radio access network and the second radio access network that can be accessed according to the service type of the service initiated by the user or the current signal quality , initiate PDP context activation to the core network equipment through the selected wireless access network, for example: if the service initiated by the user is an online service, you can select a 3G wireless access network; if the service initiated by the user is a short message service, you can Select 2G wireless access network.

[0152] When the dual-mode dual-standby terminal implements the...

Embodiment 3

[0167] This embodiment mainly involves the network side initiating the PDP activation process. In this embodiment, when there is service data sent to a dual-mode dual-standby terminal that can use one International Mobile Subscriber Identity (IMSI) to access two types of wireless access networks, the core network equipment determines to send to the dual-mode dual-standby terminal The wireless access network to be used when the terminal transmits service data initiates PDP context activation to the dual-mode dual-standby terminal through the determined wireless access network.

Abstract

The invention discloses a communication method for a dual-model dual-standby terminal and a corresponding communication system, wherein the dual-model dual-standby terminal can be simultaneously accessed to networks of different technologies by using a same card. A dual-model dual-standby terminal attaching method comprises the steps of: in an attaching process of the dual-mode dual-standby terminal capable of accessing two kinds of wireless access networks by using an international mobile subscriber identity (IMSI), after core network equipment receives an attachment request sent by the dual-model dual-standby terminal, carrying the IMSI of the terminal, the position information of the core network equipment and the access type information of the current access in a position updating request message sent to a subscription server, wherein the access type refers to the type of the wireless access network to which the terminal is accessed; and after the subscription server receives the position updating request message, updating the position information of the core network equipment corresponding to the IMSI and the access type information.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method for a dual-mode dual-standby terminal and a corresponding communication system. Background technique [0002] Existing communication systems include 2G (2nd Generation) mobile communication systems and 3G (3rd Generation) mobile communication systems, of which 2G communication systems include Global System for Mobile Communications (GSM for short) and Code Division Multiple Access according to different standards. (Code Division Multiple Access, referred to as CDMA) mobile communication system; and 3G mobile communication system evolved from 2G mobile communication system, GSM evolved into Wideband Code Division Multiple Access (referred to as WCDMA) mobile communication system and time division synchronization Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access, referred to as TD-SCDMA) mobile communication system, CDMA ...
