Carrier channel router

Abstract

The invention discloses a carrier channel router which is in series connected between an information source node and an overlay node of each overlay network and is used for completing the carrier channel resource scheduling among a plurality of overlay networks. The router comprises a network mixing unit and a scheduling unit; the network mixing unit is used for completing the electric connection between the information source nodes and the overlay nodes of a plurality of overlay networks and enables the sum of the carrier channel of all the overlay networks to be existed in each overlay network; and the scheduling unit is used for intercepting the signal of each overlay network and detecting the actual demand of the overlay network to the carrier channel, and realizing the dynamic scheduling of the carrier channel between at least two overlay networks. The invention has the advantages that firstly, the structure is easy to realize, a plurality of networks can be connected through the independently-provided carrier channel router, the scheduling function is realized, the construction is facilitated and the reconstruction cost is low; and secondly, the scheduling method of the invention breaks through the inherent thought limitation and enables the dynamic scheduling of the carrier channel resource among a plurality of base stations to be possible.

Description

【Technical field】 [0001] The invention relates to the utilization technology of carrier resources in a mobile communication coverage system, in particular to a carrier channel router. 【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 in the cell D1 or D2, ...

AI Technical Summary

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, which will change with the characteristics of people's activities. If a higher n value is blindly pursued in order to ensure the normal communication of customers, it will further Affects the allocation of frequency band resources and reduces the utilization 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
