Problems solved by technology

[0008] When the cellular communication system provides trunking services, if this technology is still used to allocate a wireless reverse channel for each trunking service user, it will cause a great waste of wireless reverse channels, because among many trunking service users, the same Only one user speaks at a time; doing so also impacts cell capacity

Embodiment Construction

[0019] According to the characteristics of the VGCS service, each cluster service user hears the same content at the same time, so there is no need to allocate a forward channel for each user in the same cell, and only one forward shared channel can be allocated for All users listen; in addition, each service user can speak at different times, but only one user can speak at the same time, so in the same cell, only one reverse shared channel can be allocated for all trunking service users in the cell shared.

[0020] In the voice group call service, according to the idea of ​​sharing the wireless reverse channel in the present invention, two allocation methods can be used to share the reverse channel: fixed allocation of the shared reverse channel and dynamic allocation of the shared reverse channel.

[0021] Fixed allocation of shared reverse channels is to pre-allocate a fixed reverse channel for all trunk group users in the same cell. When a user needs to speak, the fixed re...

Abstract

The invention relates to a method for allocating wireless reverse channel in group service in honeycomb communication system, it creates a wireless reverse channel and form complementary effect for each user, and provides service for group service user with shared wireless reverse channel, in order to save reverse channel resources. Several wireless terminals in the same group are allocated with a shared wireless reverse channel by the base station control center in the voice group call service, and at least allocates on forehead broadcasting channel. The shared reverse channel can be allocated to the fixed reverse channel, when user applies to speak, it uses the reverse channel, when speak is completed, the reverse channel can be used by other user.

Description

technical field [0001] The present invention relates to mobile communication technology, more specifically to a method for allocating wireless reverse channels in trunking services in a cellular communication system. Background technique [0002] The wireless channel is divided into a forward channel and a reverse channel. The forward channel refers to the channel from the base station to the wireless terminal, while the reverse channel refers to the channel from the wireless terminal to the base station. Assuming that A is a base station and B is a wireless terminal, then the communication in the direction of A->B goes through the forward channel, and the communication in the direction of B->A goes through the reverse channel. [0003] Voice group call service and voice broadcast service are two main services in the trunking communication service. The typical application of the trunking service is group call, which is characterized in that the conversation is carried ...
