Embodiment Construction
[0085] The core of the present invention is based on the existing 3G network architecture, by adding the core entity that realizes the PTT service, that is, the PTT server to realize the PTT service function, and complete the authentication and authorization of the PTT service, PTT call control, and group information. Functions such as storage and management, media replication, business statistics and billing. When establishing a call, the calling user sends an invitation INVITE message to the called user through the PTT server to establish a PTT call process; Call; after the call is completed, the user or the PTT server initiates the call release process.
[0086] In order to enable those skilled in the art to better understand the solution of the present invention, the existing 3G network architecture is briefly described first.
[0087] refer to figure 1 The schematic diagram of the 3G mobile communication network architecture is shown:
[0088] Among them, the RNS (Radi...

The invention relates to a system for realizing one-key operation in third-generation mobile communication network, wherein it comprises 3G wireless network subsystem RNS, corn network CN, and terminal supporting one-key operation PTT service, PTT server for authorizing and identifying the PTT service, controlling PTT page, storing and managing group information, copying medium, statistic service and charging; PTT terminal connected to the PTT server via wires for initializing and participating the distribution service as multicast and broadcast, to manage the group members; PTT wireless terminal wirelessly connected to the PTT server to initialize and participate the PTT service. The invention also discloses a relative method. The invention can use PTT server to realize PTT service at 3G network.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for realizing a push-to-talk service in a third-generation mobile communication network. Background technique [0002] The Push to Talk (Push To Talk) service is a half-duplex communication method. On a user terminal that supports PTT, users can conduct one-to-one or group communication in a larger range similar to a walkie-talkie function calls. The calling user presses the PTT button to speak, and the called party can answer without picking up the phone. After the calling user releases the PTT button after speaking, the right to speak is released. Other users press the PTT button to obtain the right to speak. You can speak. [0003] At present, the systems that provide PTT services mainly include: analog trunking system, digital trunking system, such as iDEN (integrated Digital Enhanced Network) system and TETRA (terrestrial trunked radio) system, and Po...
