Inter-network carrier channel supporting method

Abstract

The invention relates to an inter-network carrier channel supporting method, which comprises: step 1, a terminal relay unit is set in a first space region overlaid by a first carrier information source and is pre-set with the search feature of first carrier channels belonging to the first carrier information source; step 2, a signal interactive link between the terminal relay unit and a second carrier information source used for overlaying a second space region is established; step 3, the terminal relay unit can be used for actively detecting that whether all the first carrier channels in the first space region are busy or not according to the search feature; step 4, the terminal relay unit sends a control signal representing that whether all the first carrier channels are busy or not, and the terminal relay unit can dispatch second carrier channels of the second carrier information source for the first space region according to the control signal. In the invention, the carrier channels of overlay networks can be supported by external networks according to the actual requirement, thereby realizing the resource sharing of the carrier channels between the two overlay networks, in particular to two base stations.

Description

【Technical field】 [0001] The invention relates to the utilization technology of carrier resources in a mobile communication coverage system, in particular to a cross-network carrier channel support method. 【technical background】 [0002] In the mobile communication coverage system, with the in-depth development of network construction and the continuous improvement of network coverage, the goal of making calls anytime, anywhere has been basically realized. The biggest bottleneck of network development is that the network sacrifices a lot of network indicators in order to meet the traffic needs of users, and reduces the utilization rate of channel resources in exchange for capacity; utilization rate. [0003] by figure 1 For example, let figure 1 The middle cells D1 and D2 belong to the coverage of the base stations B1 and B2 respectively. Assuming that the two base stations B1 and B2 are used as source nodes, each has a total of n carrier channel resources. Whether it is ...

Problems solved by technology

Therefore, when the number of traffic actually required in the cell D1 is greater than n, the base station B1 cannot meet the normal call demands of all users in the cell D1 covered by it; The number is less than n, for the base station B2, it will undoubtedly cause a waste of carrier channel resources

[0004] On the other hand, the number of actual traffic demands of cells D1 and D2 is a variable, and it will change with the change of people's activity characteristics. If a higher n value is blindly pursued in order to ensure the normal communication of customers, the It will further affect the allocation of frequency band resources and reduce the utilization rate of carrier channel resources

[0005]Furthermore, the current coordination of carrier channel resources is often limited to the channel adjustment within the coverage network extended from a base station, and there is still room for breakthroughs in this thinking Space
