Embodiment Construction

[0055] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0056] refer to figure 1 , . like figure 1 As shown, when a user roams to a non-home PLMN, the user equipment and the roaming network device send an activation request, the roaming network device forwards the activation request to the first gateway, and the first gateway according to the activation request The user ID and the access point name (Access Point Name, APN) in the device obtain the gateway address of the gateway of the su...

Abstract

The embodiment of the invention provides a data transmission method and a gateway. The method includes receiving an activate request which at least comprises user an identification used for identifying identification of user equipment and an access point name (APN); and obtaining a gateway address of a gateway of a user contact attribution place, allowing user equipment and the gateway of user contact attribution place to perform data transmission so as to realize each common business. Only one APN is provided, which can reduce the number of APNs, and simplify APN management; a network structure can not be changed and a general APN which needs to go back to the contact attribution place can be flexibly configured; only the attribution place of the APN needs to be analyzed, which can simplify attribution place and reduce requirement to processing capacity of gateway equipment.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a data transmission method and a gateway. Background technique [0002] When mobile operators build large-scale General Packet Radio Service (GPRS) / Evolved Packet Core (EPC) networks, they adopt hierarchical networking for ease of management, such as China Unicom and China Mobile. The GPRS / EPC network of the province is established on a provincial basis. The provincial GPRS / EPC network is responsible for providing GPRS / EPC services to users in the province, that is, the same Public Land Mobile Network (PLMN) can be divided into It is a GPRS / EPC network with multiple contracted home places. Generally, there are the following three situations for services: services in the contracted home place of a certain PLMN; services that roam to non-contracted home places but still belong to the PLMN; services that roam to other PLMNs business. [0003] In the application scenario of ro...
