Problems solved by technology

Since the RNC needs a certain delay for resource adjustment, the user experience has seriously deteriorated at this time, and because the interference is already large at this time, there may be a risk of call drop during the adjustment process

Embodiment Construction

[0023] The radio resource management method and the radio network controller proposed by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0024] In order to solve the problem that in the environment where the Cell Portion technology is used and supports SDMA, the user terminal UE may no longer meet the space division requirements and form strong interference when the user terminal UE moves between the Portions, which seriously affects the use of users. In the first embodiment of the invention, a radio resource management method is provided, through which pre-judgment and pre-processing are performed on the status change of the space-time division multiplexing requirement of the user terminal when moving between zones, such as figure 2 As shown, the method includes:

[0025] Step S201, the network side obtains the measurement information of the current user terminal UE in the space division state, and t...

Abstract

The invention discloses a radio resource management method and a radio network controller (RNC), wherein the method comprises the steps that: a network side acquires measurement information of current user equipment (UE) under space division state, wherein the measurement information comprises received signal code power (RSCP) of uplink specific channels corresponding to different partitions; the network side determines that the difference value between the most powerful RSCP and the second powerful RSCP in the measurement information is smaller than a set threshold, and determines a partition to which the second powerful RSCP corresponds as a target partition when the duration during which the difference value is smaller than the set threshold exceeds a predetermined duration; and the network side acquires a home partition of UE which spatially divides the resource with the current UE, and regulates the resource allocation when determining that the degree of isolation between the home partition and the target partition does not meet the demand of space division. The method of the invention, before the UE changes the home partition thereof, performs prejudgment and pretreatment in advance on whether interference is formed after movement, thereby avoiding the strong interference caused by the reason that the demand of space division after movement is not met and further guaranteeing normal operation of businesses and excellent experience of users.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a radio resource management method and a radio network controller. Background technique [0002] TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) is a technical standard of the third generation of wireless communication. The wireless transmission method of TD-SCDMA is extraordinary in terms of transmission capacity. In order to make full use of the multi-antenna directivity technology of the TD-SCDMA system to further increase the transmission capacity, and to distinguish signals of different users by using the spatial characteristics, SDMA (Space Division Multiple Access) is introduced. [0003] SDMA regards spatial characteristics as a form of resource division, and uses the directivity of the antenna to optimize the use of the wireless frequency domain and reduce system costs, so that use...
