Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The invention mainly includes technologies: scalable equipment cascading structure, regional equalization algorithm, equalization algorithm based on IMSI modulo, and equalization algorithm based on purpose MAC (media access control) of user data packets.

[0022] The scalable equipment cascading structure means that the method is based on 10G processing boards and 10G switching devices, and can flexibly implement 10G data flow according to the requirement that the traffic load of each 10G processing board is not greater than 10G according to the traffic size of the access R-P data. The number of processing boards can be extended without affecting other implementation structures of the method.

[0023] The regional equalization algorithm means that after accessing the R-P interface data, the first 10G switching device can identify the region to which the PCF be...

Abstract

The invention provides a load balancing method for large-flow data of an R-P (Radio Access Network-to-Packet Data Serving Node) interface in a CDMA2000 (Code Division Multiple Access) network. The method is realized based on a processing board with the processing capacity being not lower than 10G, of a network processor and switching equipment with the switching capacity not being lower than 10G, and area-based balancing, IMSI (International Mobile Subscriber Identity) modulo balancing and other balancing algorithms are adopted in a realization process. By the application of the load balancing method, the large-flow data accessed in from the R-P interface can be sent to multiple sets of protocol analysis board cards in a balanced manner for processing, and the data of each user are ensured to be on the same set of protocol analysis board card, so that distributed data can meet the requirement for subsequently processing user data. The load balancing method disclosed by the invention is applied to scenes in which the large-flow data of the R-P interface in the CDMA2000 network needs to be subjected to access analysis.

Description

technical field [0001] The invention belongs to the technical field of CDMA2000 mobile communication, and in particular relates to a load balancing of R-P (connection between PCF (packet control function device) and PDSN (packet service data node)) interface large flow (10G to 40G) data in a CDMA2000 network The method and the device, the method and the device can evenly send the large-flow data accessed by the R-P interface to multiple sets of protocol analysis boards for processing, and ensure that the data of each user is on the same set of protocol analysis boards, so that the distribution Post-data meets the requirements for subsequent processing of user data. Background technique [0002] By accessing the relevant interface of the core network part of the mobile communication network, online analysis of data is the mainstream method of core network analysis of the mobile communication network. The large data traffic is an important feature of core network related inte...
