Embodiment Construction

[0031] Embodiments of the call setup process of the present invention will be described below with reference to the accompanying drawings.

[0032] Such as image 3 As shown, it shows a schematic diagram of the call setup signaling flow of the calling terminal in the mobile communication system of the present invention. Certainly, the method of the present invention is also applicable to the call establishment process of the called terminal.

[0033] Compared figure 1 and image 3 It can be seen that in the whole establishment process, the first process: radio resource control (RRC) connection establishment, the second process: non-access stratum (NAS) signaling connection establishment process, both are the same, in order to save space and highlight the The substantive features of the 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. ...

Abstract

The invention belongs to reducing call setup time-delay method in mobile communications systems. At present the call establishment needs a longer time, which affects quality of the subsequent delay-sensitive business to a large extent. One of the most important reasons for having a longer time to establish connection is that the length of the air interface signaling information packet is too great to transmit. The invention using wireless loading information exists to establish quasi-static parameters of the actual situation, notify part of this quasi-static parameters in advance through radio to the mobile, mobile storages this part of quasi-static parameters so reduce the size of wireless transmission of information carrying establish in the process of call establishing, so as to shorten the time to establish wireless bearing, thus shorten the whole process of call setting up delay time.

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 reduction in quality can sometimes be tolerated, but for some services that are sensitive to this connection dela...
