Resource allocation method of communication system and wireless network system

Abstract

The invention relates to the field of wireless communication and discloses a resource allocation method for a communication system and a wireless network system, which causes the utilization rate of wireless resources of a system to be promoted. In the invention, in a situation that a first wireless network system and a second wireless network system which control different physical resources have at least partial superposition in coverage range, the first wireless network system consults with the second wireless network system to allocate the controlled physical resources. Shared physical resources can be the physical resources which are allocated to one of the wireless network systems in advance but unused currently. After the allocated shared physical resources are released, the wireless network system of the other party is notified. The wireless network system can be a system comprising a wireless network controller and a base station node of a traditional network or the system comprising an evolution-base station node of an evolutional and high-speed data access network or the system comprising an evolution-base station node of a long-term evolution network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the allocation technology of physical resources. Background technique [0002] In 2006, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") passed the High Speed ​​Data Access (High Speed ​​Packet Access, referred to as "HSPA") evolution research project, and the evolved network architecture of HSPA (referred to as HSPA+ network) is based on the packet domain (PS) service, which will provide high bit rate user rate and shorter call delay for PS service; for the circuit of the current third generation mobile communication (The Third Generation, referred to as "3G") system Domain (CS) services will no longer be optimized. [0003] In the HSPA+ network, all functions of the radio network controller (Radio Network Controller, "RNC" for short) of the existing 3G system are placed on the evolved HSPA base station node (NodeB+). On t...

Problems solved by technology

[0009] The inventors of the present invention found that for NodeB+ and NodeB with overlapped coverage areas, they use different frequency resources and do not interfere with each other so that limited resources cannot be used more effectively

Since the frequency resources used by NodeB+ and NodeB are specified, they cannot match the load conditions of the equipment in the actual business process, so it may happen that one party's business is very idle, and its frequency resources are vacant, while the other party's business Very busy and the frequency resources are not enough

For example, when the PS service on NodeB+ is very idle, the utilization rate of frequency points is not high; it may be that NodeB is very busy at this time, and resources are not used enough, resulting in unreasonable resource utilization and low utilization rate of frequency point resources.
