Embodiment Construction

[0067] For the following attachment scenarios, the network attachment process in the prior art has problems of long delay and low efficiency: the user terminal uses IMSI or invalid GUTI to attach; the network side does not save the context information of the UE; the attach initiated by the user terminal The PDN Connectivity Request message included in the request message does not include the EIT (ESM Information Transfer flag, session management message transfer flag) option or the EIT is set to 0 (when the value is 0, it means that the transmission does not need to be encrypted). In this regard, the embodiments of the present invention provide an attachment method in the evolved E-TRAN and a mobility management entity, so as to reduce the time delay for the user terminal to attach to the network and improve the attachment efficiency. In the embodiment of the present invention, the attachment method may include: step A, the network side obtains the context information of the us...

Abstract

The invention discloses a method for attaching to an E-TRAN (Evolved Universal Terrestrial Radio Access Network) and a mobility management entity, which are used for reducing time delay that a user terminal is attached into a network and improving the attachment efficiency. The attaching method comprises the following steps that: in a step A, a network side acquires context information of the user terminal when receiving an attaching request sent by the user terminal; in a step B, the authentication process and the safety process between the network side and the user terminal are established; in a step C, a channel for information transmission between the network side and the user terminal is established; and in a step D, a default load between the network side and the user terminal is established, wherein the step B and the step C are executed in parallel after the step A is successfully executed and the step D is executed after the success execution of the step B and the step C is confirmed.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and a mobility management entity for attaching to an E-TRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network). Background technique [0002] With the improvement of user requirements for network performance, users hope that the time for terminals to access the network will be shorter and shorter, that is, the delay of the attachment process to the network should be as small as possible to improve LTE (Long Term Evolvement, Long Term Evolution) / SAE (System Architecture Evolution, System Architecture Evolution) network performance. [0003] At present, the initial attachment process in E-UTRAN includes the following sub-processes: sub-process 1, interaction between the network side and the user terminal to perform authentication, authentication, security confirmation, etc.; sub-process 2, in the network The side est...
