Embodiment 1

[0035] figure 2 A schematic flowchart of the context acquisition method provided by the present disclosure, the method provided by the present disclosure can be found in figure 1 shown in the networking application, such as figure 1 and figure 2 As shown, the method provided by the present disclosure can be applied to MEGW, including:

[0036] Step 202, the MEGW receives the GTP-U message on the user plane of the General Packet Radio System GPRS Tunneling Protocol sent by the base station.

[0037] In order to establish a data connection, the UE will send a service data packet to the base station. After receiving the service data packet, the base station will add a GTP-U tunnel header to the packet and add the service data of the GTP-U tunnel header. The message is the GTP-U message (GTP-U Message) in this disclosure. The GTP-U message will be forwarded to the SGW in the subsequent process.

[0038]Step 204, if the forwarding table cannot be matched according to the GTP...

Embodiment 2

[0057] In this embodiment, the same content as the first embodiment will not be described in detail.

[0058] The present disclosure will describe in detail how to trigger the base station to initiate the release of the resources of the radio access bearer to the mobility management entity MME.

[0059] image 3 The schematic flowchart provided in the second embodiment of the present disclosure, such as image 3 As shown, one implementation is:

[0060] Step 20621, simulate and generate an error indication message sent by the service gateway;

[0061] Step 20622: Send the error indication message to the base station.

[0062] For the uplink GTP-U message, the MEGW can simulate and generate the error indication message GTP ErrorIndication generated by the SGW, and the GTP Error Indication is used to inform the base station that the TEID carried in the GTP-U message in step 202 does not exist on the SGW side resources. Therefore, after receiving the GTP Error Indicaiton, the...

Embodiment 3

[0074] The present disclosure also provides a context acquisition device, which is used to execute the method provided by the above implementation, Figure 5 A schematic structural diagram of a segment identifier issuing apparatus provided in Embodiment 3 of the present disclosure, such as Figure 5 As shown, the device includes: a receiving module 501, a judging module 502, a triggering module 503, and a monitoring module 504;

[0075] A receiving module 501, configured to receive a general packet radio system GPRS tunneling protocol user plane GTP-U message sent by a base station;

[0076] The judging module 502 is configured to determine, according to the GTP-U message, where the source IP address of the inner layer data packet of the GTP-U message is located when it is determined that the GTP-U message cannot match the forwarding table and the forwarding table cannot be constructed. Whether the corresponding user equipment UE has been attached online without being monitor...

Abstract

The present disclosure provides a context acquisition method and device. When the method fails to match the forwarding table after receiving the GTP-U message, if the UE is found to be attached online, it means that the MEGW has missed the interception of the initiation of the attach process between the UE and the MME. At this time, the base station can be triggered to initiate the release of the resources of the radio access bearer, and the MME and the UE can be triggered to re-establish the radio access bearer, and the MEGW can detect the bearer context information again through the process of re-establishing the radio bearer.

Description

technical field [0001] The present disclosure relates to network communication technologies, and in particular, to a context acquisition method and apparatus. Background technique [0002] With the development of mobile communication technology, the services carried by the mobile communication network are becoming more and more abundant, and new services such as video surveillance, smart manufacturing, and smart parks have emerged, posing new challenges to the capacity, bandwidth, and real-time performance of mobile communication networks. The concept of MEC (Multi-access Edge Computing, multi-access edge computing) is the key field of current mobile communication research in the industry. It explores how to keep user business data in local computing, reduce the pressure on the transmission network and core network, and meet real-time business needs. , Improve user experience. [0003] figure 1 It is a network architecture diagram in the prior art. The network includes UE ...
