Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0024] The basic idea of ​​the present invention is: for the mobile station in DTM mode, during the update process of routing area and location area, execute DTM CS release function, keep the packet domain connection, so as to reduce the interruption of packet domain business.

[0025] see figure 2 In the illustrated embodiment, the routing area and location area update process in this embodiment mainly includes the following steps:

[0026] Step 201: The mobile station performs routing area update with the SGSN.

[0027] Step 202: When releasing the CS domain connection, the mobile station sends a system information request to the network side that does not carry an indication of prohibiting execution of the DTM CS release function.

[0028] Wherein...

Abstract

The invention discloses a method to reduce interruption of grouped realm business, for the mobile station at double transmission model (DTM) in the update process of route area and location area, implement the circuit domain release (DTM CS release) function in double transmission model, and maintain a link between grouped realm. The method can reduce interruption of grouped realm business at route area and location area in the update process, guarantee the continuity of the grouped realm business, so as to improve the service quality of grouped realm business.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for reducing service interruption in packet domain during routing area and location area update process. Background technique [0002] Dual Transfer Mode (DTM) technology is a technology that can simultaneously realize voice connection and data connection on the Global System for Mobile Communications (GSM) / Enhanced Data Rate GSM Evolution (EDGE) network. Provide circuit domain (CS) service and packet domain (PS) service to mobile station (Mobile Station, MS) at the same time. [0003] For the mobile station in DTM mode, since the system messages of the CS domain service and the PS domain service are received in the CS domain, if the CS domain connection is released, the PS domain connection must also be released. If the current packet domain service has not ended, the mobile station needs to re-read the system information and re-establish the packet domain connection....
