AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned NB IOT technology, if the UE undergoes a recovery process across base stations, and the user text information acquisition across base stations cannot be achieved when the X2 interface does not exist, the recovery process cannot be completed
At the same time, in the NB IOT technology, since the user only has the connection state and the idle (IDLE) state, and the core network is aware of the change of the user state, there is no situation that the user will still have data to reach the source base station after the user hangs up.
In the 5G system, it is different. Users are in an inactive state controlled by the network side, and the core network does not perceive changes in user status. For users in the 5G system, location area updates will be frequently triggered in the following two situations, resulting in User energy loss: The network side cannot perceive the user's mobile location due to the location change caused by the user's movement in the inactive state; or, the user moves in a small area, such as the cell area

Embodiment

[0304] Embodiment Scenario 1: The mobile management anchor point remains unchanged in the distributed network architecture

[0305] Such as Figure 14 shown, including the following steps:

[0306] Step 1401: UE triggers an air interface recovery request, and the request type is RAU update. The RAU update message carries one or more of the following information:

[0307] Source RAN location area information, such as RAI;

[0308] UE identification, such as S-TMSI, or user text identification, can uniquely identify the UE at the source side;

[0309] Update type: periodic RAU or event-triggered RAU;

[0310] The anchor point information of the UE in the source location area, such as the anchor point ID (it can also be information that can obtain the anchor point ID, such as parsing the anchor point ID from the cell global identifier) ​​and routing information (TAI, RAI, or through User text-related information can be indexed to the source anchor point on the RAN or CN side...

Abstract

The present invention discloses a method, device and equipment for network-side location area update. The method includes: a target radio access network RAN ​​node receives a first update request message, and the first update request message is an inactive Sent by the user equipment UE; the target RAN node generates a second update request message according to the first update request message, and sends it to the peer RAN node; the second update request message carries relevant identification information of the UE; The target RAN node receives the first update confirmation message sent by the peer RAN node, and executes a subsequent location area update procedure.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method, device and node for network side location area update. Background technique [0002] In the LTE system, for low-cost and low-throughput type terminal equipment, the research topic of Narrowband Internet of Things (NarowBand-Internet of Things, NB-IoT) is proposed, namely: in the frequency band of 200 kilohertz (kHz) Provide low-throughput wireless communication services for NB-IoT low-cost terminal equipment (User Equipment, UE). With the continuous evolution of wireless communication technology and protocol standards, the mobile packet service has undergone tremendous development, and the data throughput capability of a single terminal has been continuously improved. [0003] In order to meet the energy-saving needs of users and reduce the signaling interaction between the core network (CN) and the radio access network (RAN), the inactive state controlled by the RAN ...
