Embodiment Construction

[0024] The main concept of the present invention is that the BSC accesses the PCF entity by sending a state query message to the PCF entity, and the PCF entity detects its own state after receiving the message, and puts the detection result (ie, the state information of the PCF entity) in the state response message Return to BSC.

[0025] Further, the BSC may decide whether to connect the user call to the PCF entity according to the PCF status information in the status response message.

[0026] The PCF entity described in the present invention is a distributed PCF entity. The status of the PCF entity includes four situations: normal, failure, insufficient resources and no available PDSN (Packet Data Serving Node, packet data service node) resources.

[0027] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, the PCF entity state detection process in the present inv...

Abstract

The invention provides a method for a base station controller to acquire state of a packet control functional (PCF) entity, which comprises that: the base station controller sends a state query message to each PCF entity connected with the base station controller; and after receiving the state query message, the PCF entity detects personal state, puts personal state information in a state response message, and returns the personal state information to the base station controller. The method enables the base station controller (BSC) to detect the state of the PCF entity in real time so as to provide basis for the BSC to select the PCF entity for user access call and prevent the BSC from accessing the user call to the failed PCF to cause call failure.

Description

technical field [0001] The invention relates to the field of CDMA (Code-Division Multiple Access, Code Division Multiple Access) mobile communication systems, in particular to a method for a base station controller in the CDMA system to acquire the state of a PCF entity of a packet control function. Background technique [0002] In the CDMA wireless network, the PCF (Packet Control Function) entity is mainly responsible for cooperating with the BSC (Base Station Controller, base station controller) to connect packet data users to the PDSN (Packet Data Serving Node, packet data service node) superior. According to the relevant provisions of the CDMA2000 standard, the BSC is connected to the PCF through the A9 (control plane interface) / A8 (media plane interface) interface. The PCF has the functions of establishing, maintaining and terminating the two-layer link connection with the PDSN, managing wireless resources, routing, and buffering packets. data functions.
