Embodiment Construction

[0022] Such as figure 1 As shown, the working process of the cluster method between the packet data service nodes described in the present invention is as follows:

[0023] First, the PDSN selects a cluster group to join and joins the group. In the future, the implementation of cluster policies and the exchange of cluster information will all be carried out in this group;

[0024] Secondly, each PDSN in the group regularly or irregularly notifies its own cluster information, including its own load capacity, current load situation, recent access and offline MS, etc., and the PDSN records the information sent by other PDSNs in the " Cluster PDSN Table" and "Cluster MS Table". Among them, the role of the "cluster PDSN table" is to record the load information of all PDSNs in the cluster group, and the PDSN with the lightest load can be found from this table. This table is very useful in load balancing. The "cluster MS table" The role is to record the basic information of all MSs...

Abstract

The method belonging to CDMA mobile communication area includes following steps. A package data service node (PDSN) selects and joins a cluster group. Each PDSN broadcasts timed or not timed information of own cluster. PDSN records information from other PDSN onto 'cluster PDSN table' and 'cluster MS table'. When a user is switched in a PDSN, the PDSN queries cluster MS table first. If the user is found in the table, the PDSN recommends the user to PDSN just switched in; otherwise, the MS is a new user. PDSN queries cluster PDSN table for new user. A PDSN with most light load is found. The new user is recommend to a PDSN with most light load. The invention realizes load balancing and intelligent selection between PDSNs in cluster so as to prevent unnecessary switching and reduce communication discontinuity in moving procedure.

Description

technical field [0001] The invention relates to a clustering method between Packet Data Serving Nodes (hereinafter referred to as PDSNs). It belongs to the field of CDMA2000-1x packet data software. Background technique [0002] With the continuous integration and development of wireless communication network and IP network, the application of packet data service in CDMA network will become more and more extensive, and its status and role in people's daily life and work will become higher and higher. With the continuous promotion and application of new services, the data volume of packet services will become larger and larger, and there will be more and more PDSNs serving as CDMA2000-1x wireless packet service access gateways. How to organically integrate these PDSNs As a whole, it is particularly important to achieve load balancing between them and reduce the switching of mobile stations between different PDSNs. [0003] At present, there are already some technologies for...
