A multi-standard network resource allocation method applied to a distributed integrated access system

Abstract

The present invention discloses a multi-system network resource allocation method applied to a distributed integrated access system, comprising: (1) initializing resource allocation parameters; (2) calculating the Wi‑Wi of each UE in the current resource allocation state Fi connection status; (3) Construct a Wi-Fi connection feasible solution set; (4) Traverse the Wi-Fi connection feasible solution set, do linear programming, select the solution with the optimal system data rate, and use this solution to update the current system optimal solution ; (5) Judging whether the convergence condition is satisfied, if not, return to (2); (6) The distributed integrated access system allocates spectrum resources according to the current system optimal scheme. This method integrates the license-free LTE technology into the distributed integrated access system, realizes multi-standard network resource allocation, increases the integration degree and networking flexibility of the original mobile communication coverage equipment, reduces the competition intensity of a single-standard network, and improves Utilization of spectrum resources.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a multi-system network resource allocation method applied to a distributed integrated access system. Background technique [0002] With the rapid development of mobile services, people's demand for data is increasing year by year. Facing this increasingly severe challenge, on the one hand, it is necessary to improve the utilization rate and reuse rate of the limited existing spectrum resources; Spectrum resources are available. Therefore, the industry and academia have proposed a new technology, LTE-U (LTE Advanced in Unlicensed Spectrum), which uses license-free frequency band resources to expand the capacity of LTE networks. The characteristics of LTE-U make LTE-U an important supplement to Wi-Fi. LTE-U technology can be used for short-distance transmission, sharing the license-free radio frequency band used by Wi-Fi. [0003] A multi-homing network refers to a network m...

AI Technical Summary

Problems solved by technology

[0006] The original distributed integrated access system does not support the license-free LTE access technology, and only Wi-Fi with low spectrum utilization is available on the license-free frequency band, which cannot make full use of the license-free spectrum resources
