Embodiment Construction

[0076] The present invention is a method for optimizing the call setup delay of a push-to-talk service based on a cellular network, such as Figure 4 shown, including the following steps:

[0077]In step s401, the user equipment sends a radio resource control connection establishment request message to the radio network controller, and the message includes PTT session establishment information. Wherein, the PoC session establishment information includes calling PoC session establishment information and called PoC session establishment information. In addition, when the user equipment as the calling terminal or as the called terminal receives paging from the network side, it notifies the radio network controller to establish a PoC session. When the user equipment is the called terminal, the specific process includes: the core network sends the radio network controller A paging message, the message includes the called PoC session establishment information, and the radio network...

Abstract

The method comprises: user's device sends the radio resource control connection establishment request containing PoC session establishing information to the radio network controller; the radio network controller indicates the user device to pre-establish a transmission channel carried by PoC radio access through radio resource control connection establishing message; the configuration parameters of the transmission channel is set with a maximal data rate of PoC service; establishing the radio access and enabling the contest of packet data protocol, and according to the configuration parameter of transmission channel, setting the QoS parameter in packet data protocol context; according to the QoS parameter, user's device makes SIP signaling interaction with the PoC server to establish PoC session.

Description

technical field [0001] The invention relates to a push-to-talk technology based on a cellular network in a broadband code division multiple access system, in particular to a method for optimizing the call setup delay of a push-to-talk service based on a cellular network. Background technique [0002] Trunk communication, namely PTT (Push To Talk), as an important branch of mobile communication, is mainly used for command and dispatch communication by professional users such as public security and firefighting, and is generally networked separately. The trunking communication adopts half-duplex, one-to-one or one-to-many communication methods, the calling party only needs to press a button to connect, and the called party can answer without picking up the phone, so it has fast connection speed, reliability and safety Higher features. [0003] With the development of mobile communication services, operators hope to implement PTT services for ordinary users in the public mobil...
