Problems solved by technology

[0008] During the specific implementation process, the inventors of the present invention found that RRM Spare_Capacity_Req or RRM Spare_Capacity_Rpt may reach the destination BS after multiple forwardings, resulting in time delay, and the timeliness of RRM report is short. It is often wrong to make corresponding decisions based on the content of the report, which instead leads to low utilization of system wireless resources

Embodiment Construction

[0056] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] refer to figure 1 , is a flowchart of an RRM request in an embodiment of an RRM request and reporting method of the present invention;

[0058] In this embodiment, in the WiMAX system, the first BS sends an RRM spare capacity request message (RRM Spare_Capacity_Req) ​​to the second BS, and the RRM Spare_Capacity_Req is forwarded by the ASN GW as an example; understandably, although this embodiment uses Forwarding through one ASN GW obviously can be forwarded through multiple ASN GWs in practical applications.

[0059] Step S101, the first BS sends RRM Spare_Capacity_Req to the ASN GW;

[0060] When the first BS needs to obtain the RRM remaining capacity of the second BS, it may request the second BS to respond through the RRM Spare_Capacity_Req message, and obtain the RRM remaining capacity of the second BS t...

Abstract

A method for requesting radio resource management(RRM) includes: a first base station(BS) sends a RRM spare capacity request message to an access service network gateway(ASN GW); the RRM spare capacity request message carrying the information indicating the generated time of the RRM spare capacity request message; the ASN GW forwards the RRM spare capacity request message to a second BS; and the second BS judges whether the RRM spare capacity request message is invalid according to the information indicating the generated time of the RRM spare capacity request message carried by the RRM spare capacity request message. A method for reporting the radio resource management, a base station and a system are also provided by the present invention. The present invention can efficient identify the outdated RRM message and discard it, and prevent the RRM decision error leaded by the outdated RRM message which is received since the network delay.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a radio resource management (RRM, Radio Resource Management) requesting and reporting method, a corresponding base station (BS, Base Station) and a system. Background technique [0002] RRM is a function of the access service network (ASN, Access Service Network) in the network architecture of the World Interoperability for Microwave Access (WiMAX, World Interoperability for Microwave Access). It improves the use of wireless resources by monitoring and managing wireless resources. efficiency. Each BS can learn the remaining resources of other BSs through RRM, so as to allocate resources and improve the use efficiency of wireless resources. [0003] BSs cannot directly communicate with each other, and the relay of the ASN gateway (GW, gateway) is required. The ASNGW receives the RRM remaining capacity request message of a BS, and then forwards it to the second BS, ...
