Embodiment Construction

[0029] In the present invention, different types of bandwidth priorities are pre-set, including: bandwidth priorities P(Qi) of different groups where users are located, priorities P(Sj) of different services in multimedia services sent by users, The priority P(Uk) of different users. Among them: i, j, and k respectively represent different groups, different services, and different users. Then, the weights of different types of priorities can be determined as required, that is, the weights of the two types of priorities, group and business, can be set. It can be group priority or business priority. When the priority of the group is the same and the priority of the service is also the same, the priority of the user needs to be considered. If the user's priority is also the same, that is, P(U1)=P(U2), then the system determines the allocation of bandwidth according to the user's served historical information metric Wh when allocating bandwidth, and the historical information me...

Abstract

This invention discloses one method to send integral wireless communication system to media flow, which in aligning wide band aim for different media flow and comprises the following steps: according to preset group priority or business priority aligning; then sending media flow on aligned wide band; through considering different set or business priority to realize proper aligning between set group and business signal channel wide band to meet wide band Quos requires.

Description

technical field [0001] The invention relates to a wireless communication system, especially a method for sending forward media streams in a cluster wireless communication system. Background technique [0002] The trunking communication system refers to a dedicated mobile communication system in which multiple users share a group of wireless channels and use these channels dynamically. It is mainly used in enterprises, public security, police and military departments that have high requirements for command and dispatch functions. The trunking communication system can be divided into analog trunking communication system and digital trunking communication system according to the technical standards adopted inside the system. Two TDMA (Time Division Multiple Access) standard digital trunking systems widely used at present include iDEN (integrated Digital Enhanced Network) digital trunking communication system and terrestrial trunking radio TETRA (Trans-European Trunking Radio C...
