Problems solved by technology

[0003] Since the transmission of data in the Internet is not controlled by the core network, this will lead to the transmission delay and reliability of the network are not guaranteed, and the pressure on the mobile network will be greater

Embodiment 1

[0162] This embodiment one corresponds to the above scenario four, that is, the first UE migrates from the first GW-U of the first base station to the third GW-U of the second base station, and the third GW-U has not yet established the required Before the migration of the first UE, the first IN-PDN is distributed across the first GW-U and other GW-Us. After the migration of the first UE, the first IN-PDN on the first GW-U There are no other UEs.

[0163] In this scenario, the signaling interaction process between network elements is as follows: Figure 6 Shown:

[0164] 1. The target eNB sends a Path Switch Request (Path Switch Request) message to the MME, carrying the GTP address and TEID of the target eNB, and carrying the target TAI information at the same time.

[0165] The target eNB here is equivalent to the second base station above.

[0166] 2. The MME sends a Modify Bearer Request message to the GW-C, and notifies the GW-C of the General Packet Radio Tunneling Pro...

Embodiment 2

[0208] Embodiment 2 corresponds to the above scenario 8, that is, the first UE detaches from the first GW-U, and before the first UE detaches, the first IN-PDN is distributed across the first GW-U and other GW-Us, and the first IN-PDN There is no other UE in the first IN-PDN on a GW-U.

[0209] In this scenario, the signaling interaction process between network elements is as follows: Figure 7 Shown:

[0210] 1. The first UE deattaches from the source GW-U. The IN-PDN controller queries the current IN-PDN distribution information, and finds that there is no UE other than the first UE in the first IN-PDN on the source GW-U, and the first IN-PDN still exists on other GW-Us. distributed. According to the query result, the IN-PDN controller updates the IN-PDN distribution information between the first IN-PDN and GW-U, between the first IN-PDN and the first UE, and between the first UE and GW-U. mapping relationship, and query the tunnel identifier corresponding to the first I...

Abstract

A network management method and controller, which can realize the dynamic expansion and contraction of the IN-PDN intranet packet data network in the scenario of UE migration or detachment, and can still ensure the local networking of the UE when the UE migration or detachment occurs Intra-PDN service continuity, and timely recovery of unused IN-PDN resources, avoiding the waste of IN-PDN resources.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network management method and a controller. Background technique [0002] Such as figure 1 As shown, in the network architecture of the third generation mobile communication technology (3rd Generation, 3G for short) or the fourth generation mobile communication technology (4th Generation, 4G for short), the user equipment (User Equipment, UE for short) through the core The network and the border gateway are connected to a packet data network (Packet Data Network, PDN for short). In the 3G / 4G network architecture, the PDN is in the Internet (internetwork, referred to as: internet), the core network is responsible for sending data to the border gateway, and the border gateway sends the data to the PDN in the internet. [0003] Since the transmission of data in the internet is not controlled by the core network, this will lead to a lack of guarantee in the transmission de...
