Embodiment Construction

[0055] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0056] Figure 8 It is a flowchart of a method for querying a gateway according to an embodiment of the present invention. The above method is mainly applied in the network for realizing local access. In order to shield the modification of the existing mobility management unit by introducing the local access service, it is necessary to add a selection management unit in the network for realizing local access. Such as Figure 8 As shown, the method for querying the gateway in the embodiment of the present invention mainly includes the following processing:

[0057] Step S802: The selection management unit sends a gateway query request to the DNS server, wherein the gateway query request includes AP...

Abstract

The present invention provides a method and system for querying gateway, applied in realizing locally accessed network. The network comprises: a selection and management unit. The method comprises: the selection and management unit sending a gateway query request to a domain name server (DNS), the gateway query request comprises APN information and / or location information, or the combination of at least one of the APN information and the location information and instruction information for selecting core network gateway; the selection and management unit receives a gateway query response returned from the DNS, the response carries one or more gateway addresses obtained through the query. The technical scheme provided in the present invention can effectively prevent modifications to the current mobility management unit caused by introducing local access service.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for querying a gateway. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and at the same time reduce the operating costs of operators, the Third Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) standard working group is working on the research of the evolved packet system (Evolved Packet System, referred to as EPS). [0003] figure 1 A schematic diagram showing the structure of an evolved packet domain system, such as figure 1 As shown, the entire EPS system is divided into two parts, the wireless access network and the core network. The core network includes a Home Subscriber Server (HSS for short), a Mobility Managem...
