Embodiment Construction

[0039] The essence of the present invention is to allow the side that initiates the abnormal termination to send a disconnection request message to the opposite end, and to make the other side feed back a message that the connection has been disconnected to the initiating side; Ability to handle abort calls. That is, aiming at the current process defects, improve the process of abnormal call termination on the calling side (Outgoing Side) and the process of abnormal call termination on the called side (Incoming Side) to improve the fault tolerance of both parties. The details of the method are as follows:

[0040] The perfect steps for the calling side of process A to actively terminate the call:

[0041] Step 1. When the calling side is in the TCS call state Call initiated (1), if an abnormality is encountered and the call flow is to be terminated actively, a TCS CC RELEASE message must be initiated to enter the TCS call state Release request (19);

[0042] Step 2. When the ...

Abstract

A method for abnormally interrupting a call based on TCS includes: 1) sending a connection release request message RELEASE to an incoming side by an outgoing side when encountering an abnormal situation, and changing the state of the outgoing side into a connection release request state RELEASE REQUEST; 2) sending a connection release complete message RELEASE COMPLETE to the outgoing side by the incoming side when receiving the connection release request message, and changing the state of the incoming side into a null state NULL; and 3) changing the state of the outgoing side into a null state after receiving the connection release complete message at the outgoing side. The present invention can effectively improve the error tolerance of both the outgoing side and the incoming side of the voice call.

Description

technical field [0001] The present invention relates to the field of short-distance wireless communication, and specifically relates to bluetooth technology. Background technique [0002] Bluetooth technology is an open standard, short-range, low-cost wireless communication technology. It can connect various communication devices wirelessly. A device can connect up to seven other Bluetooth devices. It works in the 2.4GHz ISM free frequency band, and the transmission distance is 10cm to 10m. If the power is increased, the transmission distance can reach 100m. The technology has low power consumption, little harm to the human body, and supports multiple application models. In recent years, the integration of Bluetooth technology on mobile terminals has become increasingly popular. Major mobile device suppliers such as Nokia, Motorola, Sony-Ericsson, LG, and ZTE have launched a variety of Bluetooth mobile terminals. At present, the number of mobile terminals carrying Blueto...
