Problems solved by technology

This mechanism improves the system capacity through the cooperation of macro base stations and micro base stations. It can have good performance in traditional network scenarios, but in the scenario where access points are densely deployed and there is no macro base station, it can only be directly connected by micro base stations. Collaborate to pass data back and forth
[0006] In the ultra-dense network scenario, access points are densely deployed, and the load status of each access point and the link status between access points will continue to change with the number of users and channel quality, so a fixed backhaul is always used Routing will no longer be a more efficient and energy-saving backhaul method; in addition, when a large number of access points are densely deployed and the network topology is complex and changeable, the traditional centralized backhaul method will no longer be applicable

Embodiment Construction

[0054] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0055] A distributed wireless backhaul routing algorithm of the present invention first comprehensively considers the network topology distribution and the load status of the access point, selects a BAP from all the APs serving the same user to be responsible for returning the user's data, and all BAPs in the network Plan their backhaul links in a distributed way, BAP broadcasts its backhaul request signal, and the surrounding BAPs and idle APs consider their own interference information, channel quality conditions and load conditions, and score through the access points proposed in this paper The mechanism calculates its own score, and finally, selects the AP with the highest score and establishes a backhaul link with it. Finally, through repeated repetitions, the user's data is finally transmitted back to the core network through the LSC.

Abstract

The invention discloses a distributed wireless backhaul routing algorithm, belongs to the field of wireless mobile communications, and particularly relates to the distributed wireless backhaul routing algorithm based on score and location awareness. The algorithm comprises the steps that backhaul request signals are broadcast at the service of backhaul nodes of users, the nodes AP meeting the requirements calculate their own scores according to an effect function of a score mechanism, plan broadband resources of a network and report response signals to the backhaul nodes simultaneously, the backhaul nodes select the AP with the highest score as the next single hop, hopping is conducted in sequence to reach a local service center finally, and data is returned to a core network. According to the algorithm, it is guaranteed that on the premise that the backhaul data rate requirements of the user are met, a complete wireless backhaul path is planned, the very high success rate is achieved, route planning is flexible and reasonable, part of computation tasks of a system are unloaded to all access points, and the system management cost is less.

Description

technical field [0001] The invention belongs to the field of wireless mobile communication. In a user-centered ultra-dense network, a wireless backhaul routing algorithm based on score and location awareness is proposed for the backhaul of access points, which is a distributed wireless backhaul routing algorithm. . Background technique [0002] Ultra-dense networking technology can effectively increase network capacity and expand network coverage by deploying low-power access points in hot spots on a large scale. It has become one of the key technologies of 5G. Ultra-dense networking improves network throughput by reducing the path loss between base stations and end users. At the same time, with the increase of high-traffic terminal applications, the data generated by users is also increasing, and each access point has data It needs to be backhauled back to the core network, making the backhaul link rate of the network a bottleneck in the ultra-dense network. While increas...
