Paging method and system for evolved packet system

Abstract

The invention discloses a paging method and system for an evolved packet system. The method comprises the steps that after downlink data sent to a user terminal in the dormant state are received, whether the service of the downlink data is a low priority service or not is recognized according to data characteristics of the downlink data and predetermined service priority rules; as the response to the fact that the service is the low priority service, an MME sends paging information containing low priority paging identifications to a base station, so that the base station receiving the paging information can distinguish paging caused by the low priority service, then the base station executes corresponding operations according to base station network resource using conditions, and the base station does not execute the operation of paging a user terminal in the base station covering area when the base station is in the resource constrained state. According to the technical scheme, paging of the low priority service for the terminal in the dormant state is not executed temporarily when network resources are constrained, and network resource pressure is relieved at network busy hours.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a paging method and system for an evolved packet system. Background technique [0002] In a mobile communication network, in order to use wireless transmission resources more efficiently, when there is no data transmission between the terminal and the network for a period of time, the base station will release the wireless resources allocated for the terminal, and the terminal will enter a dormant state. When the core network receives a data packet sent to a terminal in a dormant state, the core network first caches the data packet, and then starts a service request initiated by the network. The process is as follows: [0003] The mobility management entity (Mobility Management Entity, MME) will send a paging message to the base station in the location area where the terminal is registered; [0004] The base station pages the terminal within its own coverage area; [0005]...

AI Technical Summary

Problems solved by technology

However, in the actual mobile communication network, due to the uncertainty of the number of services, the limited network resources may be in a very tight state, and the paging process is only triggered by the terminal state, without considering the resource load of the network, which aggravates the network In addition, the paging process will cause all base stations in a certain location area to receive paging messages from the MME to further page the terminal, which will increase the load on the network and cause more tension in network resources.
