Problems solved by technology

However, in the current operation process, even if the mobility management entity confirms that there is no need to establish an IP offload connection, the network element on the wireless side still transmits the local gateway information to the network side, resulting in information redundancy, increased message length, and system processing burden

Embodiment Construction

[0055] In general, during the establishment, update, or activation of an IP offload connection, only after receiving a message from the mobility management entity to query the information of the local gateway, the network element on the wireless side or the network element management system returns the local gateway information to the mobility management entity . The process of establishing or updating or activating the IP offload connection includes: an attach process, or a PDN connection establishment, or a PDP context activation, or a service request process, or a handover process, or a location update process. When the mobility management entity queries the home base station gateway or network element management system for local gateway information, the mobility management entity may send an S1 or Iu message or a new message to request local gateway information from the wireless side network element or the network element management system, and the message used to request ...

Abstract

A method and system for obtaining network element information are disclosed in the present invention, wherein the existing of a household base station gateway and / or the permission of an Internet Protocol (IP) shunt connection are determined during the IP shunt connection processing, and the household base station gateway or a network element management system sends local gateway information to a mobility management entity. The method and system in the present invention are no longer the same as the existing technology, in which a wireless side network element sends the local gateway information to the network side even if the mobility management entity determines that the IP shunt connection does not need to be established, but it is guaranteed as much as possible that the local network gateway information is sent only when it is required, thus information redundancy can be avoided as much as possible, message length may not be increased, and processing load of the system can be decreased effectively.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for acquiring network element information. Background technique [0002] The 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP) Evolved Packet System (EvolvedPacketSystem, EPS) is composed of Evolved Universal Terrestrial Radio Access Network (EvolvedUniversalTerrestrialRadioAccessNetwork, E-UTRAN), mobility management unit (MobilityManagementEntity, MME), service Gateway (ServingGateway, S-GW), packet data network gateway (PacketDataNetworkGateway, P-GW or PDNGW), home subscriber server (HomeSubscriberServer, HSS), 3GPP authentication, authorization and accounting (Authentication, Authorization and Accounting, AAA) server, policy and accounting It is composed of Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF) entity and other supporting nodes. [0003] figure 1 is a schematic diagram of the EPS system...
