Problems solved by technology

Due to the particularity of the application field of trunking communication, trunking communication has high requirements for call establishment, and generally requires that the call establishment delay is not greater than 1s, so directly using the existing call establishment method for trunking communication is far from satisfying the needs of trunking users. Requirements for fast call setup

Embodiment Construction

[0067] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0068] In a mobile communication system, a calling user initiates a call to a single called user through a mobile terminal. figure 2 Shown is the quick call setup process of a preferred embodiment of the present invention, the call utilizes the existing mobile communication network, specifically including:

[0069] Step 21, the calling user UE1 sends a "Push to Talk" RRC connection request (PTT RRC CONNECTION REQUEST) to the UTRAN to which it belongs to initiate a call.

[0070] The "push to talk" RRC connection request includes the following contents: calling user UE1 identity (InitialUE Identity), call establishment cause (Establishment Cause) and called user information. Among them, Establishment cause is the newly added call type Terminating PTT C...

Abstract

The disclosed method to build calling fast comprises: the calling user sends request contained called user information for building connection to the network; the network calls the called user according to the information, and configures the channel source between calling and called users; once receiving information, the called user sends request for building connection to the network; the network configures channel source according to called user request; both the calling and called users send calling to network to build complete information; the network notifies them for dialogue and ends calling build process. This invention saves time to meet cluster users request.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for quickly establishing a call. Background technique [0002] The existing mobile communication standards stipulate the call establishment process, as follows figure 1 The displayed call establishment process of the third generation mobile communication (3G) standard is used as an example for illustration, and the process includes the following steps: [0003] Step 11: The call connection establishment process on the calling side. This step specifically includes: [0004] 111. Establish a signaling connection of the Uu interface between the calling user UE1 and the radio access network (UTRAN). The Uu interface refers to the interface between the calling user UE1 and the UTRAN. [0005] This step establishes a radio resource control (RRC, Radio Resource Control) connection between the calling user UE1 and the UTRAN, that is, a signaling connection of the Uu interface. The...
