Embodiment Construction

[0032] 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.

[0033] Based on the problem in the related art that the continuity data of the UE cannot be obtained after the UE is handed over, an embodiment of the present invention provides a method for obtaining information, and the process of the method is as follows figure 1 As shown, including step S102 to step S104:

[0034] Step S102, the core network receives the task of tracking the UE from the base station;

[0035] In step S104, the core network sends a command to obtain the relevant information of the UE to the base station according to the task of tracking the UE, wherein the relevant information of the UE includes: IMSI information of the UE.

[0036] The embodiment of the present invention adopts...

Abstract

The invention discloses a method and system for acquiring information, an evolved packet core network and an evolved node B. The method comprises the following steps: the evolved packet core network receives a task for tracking user equipment (UE) from the evolved node B; and the evolved packet core network transmits a command for acquiring UE-related information to the evolved node B according to the task for tracking the UE, wherein the UE-related information comprises information on international mobile subscriber identification number (IMSI) of the UE. The problem that the continuity data of the UE can not be acquired after the UE is switched in related arts is solved through applying the method, the system, the evolved packet core network and the evolved node B, thus the data with continuity is acquired and the system performance is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an information acquisition method, system, core network (Evolved Packet Core Network, EPC for short) and base station (Evolved Node B, eNodeB for short). Background technique [0002] The entire evolved packet system (Evolved Packet System, referred to as EPS) consists of three parts: EPC, eNodeB, and user equipment (User Equipment, referred to as UE). Among them, the EPC is responsible for the core network part, the EPC signaling processing part is called the Mobility Management Entity (Mobile Management Entity, MME for short), and the data processing part is called the Serving Gateway (S-GW for short); the eNodeB is responsible for connecting The network access part is also called an evolved radio access network (Evolved UTRAN, E-UTRAN for short), and the UE usually refers to a user terminal. [0003] As an important part of the entire EPS system, the eNodeB is crucial to th...
