Abstract

The invention provides an improved C-RAN network architecture and a resource dispatching method. The method comprises the following steps of receiving user request information through a remote wireless unit, and sending the request information to a baseband processing unit; receiving the request information through the baseband processing unit, and sending the request information to a controller; calculating the load size required by the request through the controller, and comparing the load size with a load threshold value of a local baseband processing unit; if the required load is larger than the load threshold value of the local baseband processing unit, mapping a user request to other baseband processing units in a baseband processing pond so as to carry out resource processing through the local baseband processing unit according to a dispatching mechanism. Through the method, the problem of resource dispatching between the baseband processing units in the communication field can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of convergence access network, and more specifically, relates to an improved C-RAN network architecture and resource scheduling method. Background technique [0002] In the wireless communication cellular network system, the number of access users and the amount of business data that each cell needs to carry are random and unevenly distributed, especially problems such as traffic bursts and network congestion caused by hotspot cells, making The load in the whole system is in an unbalanced state, therefore, realizing the resource scheduling of each cell has become one of the problems to be solved urgently in the mobile communication system. At the same time, with the gradual rise of 5G wireless technology, in addition to traffic increases, traffic bursts or fluctuations, the access network also needs to meet other requirements, such as providing business users with higher security, network availabilit...
