Problems solved by technology

[0005] In the process of implementing the present invention, the inventor found that in the SGSN pool networking mode, one PCU is connected to multiple SGSNs, and the users under one PCU will be distributed in multiple SGSNs. If the PCU still uses the existing flow control mode Report flow control parameters, that is, use the method of leaky buckets. The PCU reports the total capacity of the bucket, the current amount of data to be processed in the bucket, and the flow rate. The SGSN calculates the data rate that can be delivered to the PCU based on these data. Downlink data at this data rate, the result is that the communication data exceeds the processing capacity of the PCU and overflows at the PCU, resulting in packet loss and ultimately affecting normal business operations

Embodiment Construction

[0021] An embodiment of the present invention provides that all SGSNs in the SGSN pool are configured with the same identifier relative to the PCU, such as an application scenario of a Network Service Entity (NSE, Network Service Entity). In this scenario, since the PCU identifies the SGSN through the NSE, SGSN1 and SGSN2 in the SGSN pool (assuming there are two SGSNs in the pool) are configured as the same NSE. From the perspective of the PCU, what you see is the same SGSN , so that the modification of the PCU of the existing network can be avoided to realize the networking of the SGSN pool.

[0022] In the above-mentioned networking mode, the current flow control method in the prior art is that the PCU uses the leaky bucket method to report the total capacity of the bucket, the current amount of data to be processed in the bucket, and the flow rate. Such a flow control method may easily lead to overflow of the PCU. As a result, packet loss is caused, which ultimately affects...

Abstract

The invention provides a method for controlling SGSB pool flow and an equipment thereof. Each SGSN and SGSN pool parameter ratio are confirmed and a sent data speed are confirmed according with the parameter ratio aiming at problems that in the prior art, SGSN equipment send data flow in SGSN pool exceed the control equipment ability which lead to overflow and lost package of the control equipment; SGSN can process data speed sent data according with SGSN pool which avoid overflow and lost package caused by each SGSN sent data exceeding the control equipment processing ability in SGSN pool, and ensure SGSN pool normal operation running.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for SGSN pool flow control. Background technique [0002] With the continuous improvement of the capacity demand of the serving general packet radio service (GPRS, General Packet Radio Service) support node (SGSN, Serving GPRS Support Node) in the communication network, the network structure of the SGSN pool appears. [0003] In the mobile communication network structure of the SGSN pool, only one packet control unit (PCU, PacketControl Unit) is allowed to connect to multiple SGSNs, and the multiple SGSNs constitute an SGSN pool for the PCU. Using this network structure can share the load of one PCU to multiple SGSNs in the SGSN pool, which can avoid complex network planning and increase equipment investment costs caused by the traditional mobile communication network structure, for example: when SGSN2 registers When a large number of users move to the original S...
