Embodiment Construction

[0035] Because in the prior art, when the UE initiates the Attach process, it will only report a set of temporary identification parameters (for example, only report GUTI, or only report P-TMSI and Old RAI) to the currently registered mobile control management entity, for Make the currently registered mobile control management entity locate the MME that provides services for the UE before this Attach, or the GPRS that provides services for the UE according to the unique set of temporary identification parameters reported by the UE, that is, the currently registered mobile control management entity The entity can only send an Identification Request message to an old mobile control management entity to request the IMSI of the UE, so that the current registered mobile control management entity has a relatively high probability of not being able to obtain the IMSI of the UE, and then requests the IMSI from the UE through the air interface The probability increases, so the probabili...

Abstract

The invention discloses a method for acquiring a user identifier in the attachment process, which comprises the following steps that: in the current attachment process, a mobile control management entity registered by user equipment receives at least two sets of different effective temporary identifiers reported by the user equipment, wherein each set of the effective temporary identifiers are used for positioning a mobile control management entity providing service for the user equipment before initiating the current attachment; the currently registered mobile control management entity positions at least two corresponding different mobile control management entities according to the at least two sets of the received different effective temporary identifiers, requests the user identifier of the user equipment to the at least two positioned different mobile control management entities, and acquires the user identifier which is fed back when at least one mobile control management entity feeds back the user identifier of the user equipment. The invention also discloses a corresponding device and equipment. The invention can reduce potential safety hazard of a system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for obtaining a user ID during an attach process, and user equipment thereof. Background technique [0002] An attach (Attach) process of a user equipment (UE, User Equipment) is a process in which the UE registers with the Evolved Packet System (EPS, Evolved Packet System). For example, when the UE is turned on, the UE registers in the EPS system through the Attach process to accept services provided by the EPS system. [0003] When the UE initiates the Attach process, one situation is that the UE may have registered with the EPS system before. For example, the UE is powered on during the day and registered to the EPS system. After the UE is powered off at night, when the UE is powered on again the next morning, the UE will execute the Attach process. process, re-register to the EPS system. [0004] During the Attach process, the UE may...
