Service connection releasing method, system and mobile station, base station subsystem

Abstract

The invention relates to a method for releasing service connection and a system, a mobile station and a base station subsystem to carry out the method, wherein the method comprises the following steps of: releasing the service connection between a packet control unit and a packet data service node according to the information of a request to release the service connection received when service connection is in a dormant state. The mobile station comprises: a trigger module which is used to receive a normal or abnormal disconnection / connection request; a transmitting module which is used to transmit request information to release the service connection according to the normal or abnormal disconnection / connection request. The base station subsystem comprises a receiving module which is used to receive the request information to release the service connection; a configuration module which is used to configure the information for releasing the service connection between the packet control unit and the packet data service node. The system comprises the mobile station and the base station subsystem. The invention realizes to release the service connection between the packet control unit and the packet data service node when the service connection is in a dormant state and a normal or abnormal disconnection / connection occurs.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a method and system for releasing a service connection, a mobile station, and a base station subsystem. Background technique [0002] The dormant state refers to the state that after the terminal side establishes a data service connection with the system side and there is no data traffic for a period of time, the service channel resources are released and the data connection is maintained. In the dormant state, there is no traffic transmission between the two parties, but the data connection is maintained, and the Internet Protocol (Internet Protocol, hereinafter referred to as: IP) address is not released. [0003] As shown in Figure 1, it is a network schematic diagram of prior art service connection. Taking modem dial-up as an example, host 11 dials through mobile station 12 (Mobile Station, hereinafter referred to as: MS), and through Code Division Mult...

Problems solved by technology

[0004] When in the dormant state, if the user initiates a disconnection request through Windows, unplugs the USB cable, or turns off the host to cut off the connection, the terminal side (such as the host 11) The data service connection is cut off, but the system side (such as PDSN15) still retains the IP address, and it shows that the data service is in a dormant state
