Method of setting up call connection

A method for setting up and a technology for call connection, which is applied in the field of WCDMA/TD-SCDMA systems, can solve problems such as fast call set-up that cannot satisfy professional trunking services, and long call process set-up time, so as to reduce signaling plane connection set-up time and call Settling time, reducing the effect of paging delay processing

Embodiment Construction

[0032] see figure 2 , is one of the flow charts of call establishment in the present invention, including the link establishment process of the calling user and the link establishment process of the called user. The steps of the critical path after the process optimization are described below.

[0033] The calling UE sends an RRC connection request message to the RNC, and the message carries the called number information;

[0034] After receiving the RRC connection request message, the RNC on the calling side executes the RRC connection establishment process with the calling party, and sends an initial direct transmission message to the core network before the RRC connection establishment is completed, which includes the called number information;

[0035] After the CN learns the number information of the called UE, it can immediately send a paging message (PAGING) to the called UE;

[0036] After the called UE receives the paging message, it initiates an RRC connection requ...

Abstract

The method is in use for CDMA / TD-SCDMA system and comprises: a link establishing process for calling party and a link establishing process for called party; wherein, before establishing RRC connection between the calling part and the radio network controller, the called number is transmitted to the core network; before establishing RRC connection between the called party and the radio network controller, the paging response message is transmitted to the core network. The invention can shorten the time delay of building a call connection.

Description

technical field [0001] The invention relates to a WCDMA / TD-SCDMA system, especially a call connection establishment method applied to the system. Background technique [0002] With the further exploration of 3G business types at present, trunking business has also become one of the hot topics of discussion. The basic business of the trunking system adopts the half-duplex mode. During a call, any member can be a speaker, but only one speaker is allowed at any time, and other members are listeners. At present, the existing trunking system is mainly based on GSM-R or CDMA technology, and there is no mature trunking system on the WCDMA / TD-SCDMA (wideband CDMA system / time division synchronous CDMA system) system. [0003] One of the characteristics of cluster business is that it can provide "instant communication". In particular, the service call establishment time of a professional trunking system cannot exceed 1 second at most, while the current WCDMA system call establishmen...
