Embodiment Construction

[0037] The core of the present invention is to set different thresholds and holding times for the cache occupancy rate of RLC, monitor the cache occupancy rate and the holding time of RLC in real time, if the cache occupancy rate reaches the corresponding threshold and keeps for a certain time, then take corresponding measures, Ingress control, rate negotiation, and service release are used to avoid or alleviate memory overflow.

[0038] Those skilled in the art know that in a WCDMA system, when transmitting packet services, downlink data is sent by the radio network controller and received by the user equipment; uplink data is sent by the user equipment and received by the radio network controller. All these packet data need to be buffered at the RLC layer. The timeout discarding of the RLC layer is a configurable function, which is configured by the L3 layer (network layer). If it is sent, the data is discarded and not sent again. This function can control the amount of da...

Abstract

The invention discloses a method for storing the resource control by a wireless network controller, which comprises: setting at least one buffer occupied threshold and the corresponding keep time threshold; real time monitoring the storage resource occupied rate and its keeping time; when the storage resource occupied rate and its keeping time is more than the buffer occupied threshold and its corresponding keeping time threshold, it lows the occupied of the user data to the storage resource by the buffer occupied threshold corresponding adjust mode. It also discloses a wireless network controller storage resource monitoring system which comprises a wireless switch loading managing module, an enter controlling module, a threshold matching module, an inner memory monitoring module and a comparing module.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for monitoring storage resources of a wireless network controller. Background technique [0002] WCDMA (Wideband Code Division Multiple Access), as one of the third-generation mobile communication standards, consists of CN (Core Network), UTRAN (Universal Mobile Telecommunications System Terrestrial Radio Access Network) and UE (User Equipment). The CN handles switching and routing of calls and data connections to and from external networks. UTRAN handles all radio access related functions. UE is the interface with the user. The interface between CN and UTRAN is called Iu interface, and the interface between UTRAN and UE is called Uu interface. [0003] UTRAN structure such as figure 1 Shown: [0004] UTRAN includes many RNSs (Radio Network System) connected to CN through Iu interface. An RNS includes an RNC (Radio Network Controller) and o...
