Method for user facility to attach to network and system thereof

Abstract

A method, system and device for an user equipment attaching to a network. During the course that an UE is attaching to a network, if the UE and / or the network side does not meet the basic conditions for an UE to access to an evolution network, namely the UE has no ability to access to an evolution network, or the UE has no demand to access to an evolution network, or the UE has no permission to access to an evolution network, or the network side has no ability to access to an evolution network, the activation process of a PDP context is forbidden to perform.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the technology of user equipment attaching to a network. Background technique [0002] 3G is the abbreviation of 3rd Generation in English, referring to the third generation of mobile communication technology. Compared with the first-generation analog mobile communication technology (1G) and the second-generation Global System for Mobile Communication (Global System for Mobile Communication, referred to as "GSM"), Code Division Multiple Access (Code Division Multiple Access, referred to as "CDMA") and other digital mobile communications Technology (2G), 3G generally refers to a new generation of mobile communication system that combines wireless communication with multimedia communication such as the Internet. It can handle various media forms such as images, music, and video streams, and provide various information services including web browsing, teleconferencing, and e-c...

AI Technical Summary

Problems solved by technology

[0005] (2) The evolved network architecture must minimize the delay of user data;

[0026] In practical applications, the existing technology has the following problems: there may be redundant operations in the process of UE attaching to the UMTS network, which increases the complexity of UE attaching to the network

[0030] For SAE-restricted UEs, if the user subscription information does not allow the user to use the evolved network, although the user uses a dual-mode UE, the network checks that the UE is a user restricted by the evolved network and cannot use the evolved network; or the area where the UE is located is SAE-restricted area, etc.;

[0031] The network does not have the ability to access the evolved network or is limited. For example, some operators' UMTS networks have not deployed an evolved network or some SGSNs have no interface with the evolved network or cannot establish a connection with the evolved network entity;

[0032] In the above cases, during the process of UE attaching to the network, it is meaningless for the UE to perform the PDP context activation process, and it increases unnecessary signaling processing on the UE and the network side, increases the complexity of UE attaching to the network, and reduces The speed at which the UE attaches to the network
