Embodiment 1

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

[0036] In step 202, the MEGW receives a general packet radio system GPRS tunneling protocol user plane GTP-U message sent by the base station.

[0037] In order to establish a data connection, the UE will send a service data message to the base station. After receiving the service data message, the base station will add a GTP-U tunnel header to the message, adding the GTP-U tunnel header service data The message is a 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-U message and...

Embodiment 2

[0057] The same content in this embodiment as in Embodiment 1 will not be described in detail again.

[0058] This 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 flow diagram provided for Embodiment 2 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 an error indication message GTP ErrorIndication generated by the SGW. 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 resource. Therefore, after receiving the GTP Error Indicaiton, the base station init...

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 Schematic diagram of the structure of the device for issuing segment identifiers provided by Embodiment 3 of the present disclosure, as shown in 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] The receiving module 501 is configured to receive the General Packet Radio System GPRS Tunneling Protocol User Plane GTP-U message sent by the base station;

[0076] Judging module 502, for determining that the GTP-U message cannot match the forwarding table and cannot construct the forwarding table, judge the source IP address of the inner layer data message of the GTP-U message according to the GTP-U message Whether the corresponding user equipment UE has been attached online without being monitored by the MEGW; if it has been at...

Abstract

The invention provides a context acquisition method and device. According to the method, after a GTP-U message is received, a forwarding table cannot be matched, if the UE is found to be attached on line, the MEGW misses the interception of the attachment process initiated between the UE and the MME; at the moment, the base station can be triggered to initiate the release of the resources of the radio access bearer, the MME and the UE are triggered to re-establish the radio access bearer, and the MEGW can monitor the bearer context information again through the process of re-establishing the radio access bearer.

Description

technical field [0001] The present disclosure relates to network communication technologies, and in particular to a context acquisition method and device. Background technique [0002] With the development of mobile communication technology, the services carried by mobile communication networks are becoming more and more abundant, and new services such as video surveillance, intelligent 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 current key field of 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 e...
