Embodiment Construction

[0031] To facilitate the understanding of those skilled in the art, the embodiments of the present application describe the terms involved in the embodiments of the present application.

[0032] 1. Registration: When the user turns on the UE, the UE can register after startup. Specifically: the UE can send a registration request containing the registration information of the UE to the MME, and the MME can interact with the serving gateway (serving gateway, SGW) / packet data network gateway (packet data network gateway, PGW) to register the UE The information is verified, and after the verification is passed, a signaling of successful registration is sent to the UE. At this point, the UE is registered successfully, and the registration bearer between the UE and the network device is established.

[0033]2. Single bearer: refers to that there is only one bearer between the UE and the network device. Specifically: after the UE is successfully registered, the network device can t...

Abstract

The embodiments of the application disclose a method and equipment for network recovering, which relate to the field of communication and solve the problem that UE (User Equipment) cannot acquire theservice provided by a network due to the asynchronized states of the UE and network equipment. The specific scheme is as follows: when determining that at least one paging message is sent to UE and noresponse is received from the UE within a first preset time after each paging message is sent, an MME (Mobility Management Entity) deletes the information corresponding to a bearer, stores a GUTI (Globally Unique Temporary Identifier) corresponding to the UE and starts a periodic paging timer corresponding to the UE; the MME can periodically send paging messages to the UE corresponding to the GUTI according to the periodic paging timer corresponding to the UE; and if the MME determines that the MME receives a service request signaling sent by the UE, the MME instructs the UE to reacquire service. The embodiments of the application are used in a scenario where UE cannot respond to paging.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a method and device for restoring a network. Background technique [0002] At present, most network devices have the function of reclaiming the context of user equipment (user equipment, UE), that is, the function of the evolved packet system (evolved packet system, EPS) bearer between the UE and the network device. Specifically, this function is: when the UE enters the idle state, if there is no transmission of uplink and downlink data or signaling on the EPS bearer between the UE and the network device for a preset time, the network device will send a paging message to the UE so that the UE Enter the connected state and trigger the de-registration process of the UE on the network side, expecting the UE to re-register. [0003] However, if the UE has no network signal due to entering the elevator or other reasons before receiving the paging message sen...
