Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for synchronizing an EPS bearer state, and a network side device.
Background
In an LTE network, when a mobile terminal initiates a certain specific service request (e.g., browsing a web page, sending a multimedia message, etc.) to the network, one or more EPS beacons need to be established on both the mobile terminal and the network side
(Evolved Packet System routers, Evolved Packet core network System bearer) to provide data transmission. In order to ensure normal operation of services, the states of the EPS beacons of the mobile terminal and the network side need to be kept consistent, and the current EPS beacons synchronization mechanism synchronizes the state of the network side to the mobile terminal through a TAU (Tracking Area Update) flow.
However, in some special cases, when the EPS beacons status of the mobile terminal changes, the TAU procedure cannot be triggered. For example, when initiating an EPS beacons deactivation procedure, if a failure occurs in sending a deactivation request message to the network side due to an underlying link abnormality, after the request is overtime, the mobile terminal locally deactivates related EPS beacons, but the network side is likely to be unaware of the action of the local deactivation, and then the corresponding ESP beacons states of the network side are still in an activated state, so that the EPS beacons states of the mobile terminal and the network side are inconsistent. When the mobile terminal initiates an EPS beacons activation request of the same APN (Access Point Name, Access Point) again, the mobile terminal will be rejected by the network, and finally the EPS beacons of the APN cannot be activated again.
