Embodiment Construction

[0036] Embodiments of the call setup process of the present invention will be described below with reference to the accompanying drawings.

[0037] As shown in FIG. 3 , it shows a schematic diagram of the call setup signaling flow of the calling terminal in the mobile communication system of the present invention.

[0038] Comparing Figure 1 and Figure 3, it can be seen that in the whole establishment process, the first process: Radio Resource Control (RRC) connection establishment, the third process: Radio Access Bearer (RAB) establishment process, both are the same, in order to save space and highlight the substantive features of the present invention, the two processes will not be described in detail, we believe that those of ordinary skill in the art can understand and implement them according to the current known technology.

[0039] The improvement point of the present invention lies in the above-mentioned second process: that is, the non-access stratum (NAS) signaling c...

Abstract

This invention relates to mobile communication system method to reduce call establishing time lag, which establishes time lag for lint and to impact time lag sensitive business quality to result one long time cause to fulfill all process to send out call ends. This invention can preprocess call business information in non-interface layer in interacting process to process index and process calls information according to spare situation of called end.

Description

technical field [0001] The invention relates to a call establishment method in mobile communication, in particular to a call establishment method in the third generation mobile communication system, so as to effectively reduce the call establishment time. Background technique [0002] In mobile communication, from a mobile station sending a call request to establishing a connection with the called party, a certain amount of information needs to be exchanged between the mobile station, the base station, the radio network controller and the core network, in order to communicate between the calling station and the called party. The establishment of a communication link between calling stations requires a certain duration of time. In terms of communication quality, the shorter the duration, the higher the quality. Of course, for ordinary communication services, this kind of quality reduction can sometimes be tolerated, but for some services that are sensitive to this connection...
