Embodiment Construction

[0039] The core of the present invention is to provide a data packet transmission device used in instant messaging services. For a mobile communication terminal using a text-based call control protocol, if it is necessary to receive an instant messaging service, the device detects the transmission time period of the data packet, and sends a relevant short message at an appropriate time.

[0040] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0041] Figure 6 It is a structural block diagram of a data packet transmission device applied to an instant messaging service process according to the present invention. The device includes the following structure: information sending and receiving buffer memory (111, 112), which caches instant sending and receiving information; dialogue switching control unit (140), switch the dialogue by detecting the quiet period of the above-mentioned information sending and...

Abstract

A data packet transfer unit applied in instant communication service belongs to the field of mobile communication, which is charactered in that it includes: an information transceiver buffer memory, for carrying out buffering to the instant transceiver information; a dialogue switching portion, for switching dialogue through the detection of the resting period of the said information transceivers buffer memory; a resting timer for controlling the said resting period of the information transceiver buffer memory, so as to make it not exceed a certain amount of time; a release switching portion, which releases the switch signal by outputing the data packets, and outputs the sending data packets preserved in a sending buffer memory, when the said resting timer generates a resting phase signal, or generates a switch signal from the dialogue switching portion. According to the mobile communication terminals based on the text call control protocol, if you need to receive the instant messaging services, the transmission time of the data packets can be detected through the said terminals, and can be transmitted at an appropriate moment, which can not only guarantee messages to be real-time, but also can save service costs.

Description

technical field [0001] The invention belongs to the field of mobile communication, and relates to a data packet transmission device applied to the instant messaging service process, especially, for instant messaging services of mobile communication terminals based on text and using a call control protocol, by detecting the transmission time of the data packet, Grasp the right sending time, in this way, the real-time performance of the short message can be ensured, and the service fee can also be saved. Background technique [0002] For mobile communication terminals that can implement PS (Presence service) and provide instant messaging services, a text-based call control protocol stack (Call Control Protocol Stack) is generally installed on the mobile communication terminal host. The representative of this text-based call control protocol stack is SIP (RFC3261). For mobile communication terminals that can receive instant messaging services, send and receive text messages du...
