Embodiment 1

[0077] An embodiment of the present invention provides a method for obtaining an IMSI. The execution subject of this method is a target cell, such as image 3 As shown, the method includes:

[0078] Step 301: The target cell determines that the UE needs to be handed over from the source cell to the target cell.

[0079] Step 302: The target cell obtains the UE's IMSI from the source cell; or, after the UE is handed over to the target cell, the target cell triggers the UE to perform a cell redirection process, and obtains the UE's IMSI during the UE's cell redirection process, and the UE performs cell redirection. During the redirection process, the UE accesses the target cell.

[0080] In step 302, the method for the target cell to obtain the IMSI of the UE from the source cell and the method for the target cell to obtain the IMSI of the UE by triggering the UE to perform a cell redirection process can both solve the scenario where the UE is handed over from the source cell t...

Embodiment 2

[0111] In combination with the first embodiment above, the embodiment of the present invention also provides a method for obtaining an IMSI. The execution subject of this method is the source cell, such as Image 6 As shown, the method includes:

[0112] Step 601: The source cell determines to provide the target cell with the IMSI of the user equipment UE.

[0113] Step 602: The source cell sends a message including the IMSI of the UE to the target cell, and the message is used for the target cell to obtain the IMSI of the UE.

[0114] Step 602 will be described in detail below in conjunction with the relevant description of Embodiment 1 and the drawings in the specification. In step 602, the method for the source cell to send the message including the UE's IMSI to the target cell can be divided into the following two cases:

[0115] Case 1: When the source cell and the target cell belong to the same base station, the source cell may send a message including the IMSI of the ...

Embodiment 3

[0123] Based on the first embodiment above, the embodiment of the present invention also provides a target cell, the target cell is a cell after UE handover, and the target cell can adopt image 3 For the method provided by the corresponding embodiment, refer to Figure 7 As shown, the target cell 700 includes: a determination unit 701 and an acquisition unit 702 .

[0124] A determining unit 701, configured to determine that the UE needs to be handed over from a source cell to a target cell 700;

[0125] The obtaining unit 702 is configured to obtain the IMSI of the UE from the source cell after the determining unit 701 determines that the UE needs to be handed over from the source cell to the target cell 700; or, after the UE is handed over to the target cell 700, trigger the UE to perform a cell redirection process, And the UE's IMSI is obtained during the cell redirection process of the UE, and the UE accesses the target cell 700 during the cell redirection process of the...

Abstract

The embodiment of the invention provides a method of acquiring an IMSI (International Mobile Subscriber Identification Number), a target cell and a source cell, which are used for realizing that the target cell acquires the IMSI of UE when the UE switch to the target cell from the source cell. The method comprises the following steps: the target cell determines that the UE needs to switch to the target cell from the source cell; the target cell acquires the IMSI of the UE from the source cell; or, after the UE switch to the target cell, the target cell triggers the UE to perform a cell redirection process and acquires the IMSI of the UE when the UE perform the cell redirection process, and the UE access to the target cell when the UE perform the cell redirection process.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for acquiring an IMSI, a target cell and a source cell. Background technique [0002] In a wireless communication system, the system assigns an International Mobile Subscriber Identification Number (IMSI) to a user, and the IMSI is used to identify different user equipment (User Equipment, UE), and the IMSI is stored in the Subscriber Identification Module (Subscriber Identification Module) of the UE. , SIM). [0003] At present, for the scenarios where the UE is powered on and attaches to a cell / the UE reselects to access a cell, the standard defines a method for the cell to obtain the IMSI of the UE. Such as figure 1 As shown, after the UE completes the establishment of a radio resource control (Radio Resource Control, RRC) connection with the base station where the cell it accesses is located, the base station obtains the IMSI of the UE by per...
