Problems solved by technology

[0007] 2) protocol error
[0025] However, if the LTE core network user is in the EMM-REGISTERED state, the MME may receive the ATTACH REQUEST message carried by the uplink direct transmission message. For example: after the user attach process is completed, the LTE core network user is in the EMM-REGISTERED state, The link fails, and the user performs an RRC (radio link connection) reconfiguration and re-establishment process. After the re-establishment is successful, the terminal re-attaches. Since the RRC connection already exists, it uses the direct message bearer during the attachment. NAS (Non-Access Stratum Signaling) message to send an attach request. After the core network receives the attach request, if it directly discards the message, it will cause ENB (evolved NodeB, evolved base station) resources and network resources to be released. There is no suitable reason for rejection, and the existing resources cannot be deleted to continue the ATTACH process
[0026] Therefore, when the LTE core network user is in the EMM-REGI STERED state, and the MME receives the ATTACH REQUEST message sent by the user, the network side cannot process the ATTACH REQUEST message

Embodiment Construction

[0040] Embodiments of the present invention provide a method and device for processing attach messages in a registered state. The LTE core network determines that the user is in the EMM-REGISTERED state, and when the MME receives the ATTACHREQUEST message sent by the user, it initiates a detach process and waits for the user to attach again. , so that users can access normally.

[0041] like figure 1 As shown, the method for processing an attach message in a registration state provided by an embodiment of the present invention includes:

[0042] Step S101, after determining that the user attachment process is completed, determine that the user is in a registered state;

[0043] Step S102, receiving the direct transmission message, and acquiring the user's attachment request carried in the direct transmission message;

[0044] Step S103, initiate a detach process for the user.

[0045] Since the MME first initiates the detach process after receiving the attach request sent b...

Abstract

The invention discloses an adhesion message processing method and device under a registration state, relating to a communication technology. When an LTE (Long Term) core network determines that a user is in an EMM-REGISTERED state and an MME (Mobile Management Entity) receives an ATTACH REQUEST message sent by the user, an attach removal flow is initiated, and re-attachment of the user is waited, so that a user can normally access.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and device for processing an attach message in a registration state. Background technique [0002] Under normal circumstances, the user attachment is completed, the LTE (Long Term Evolvement, Long Term Evolution) core network user is in the EMM-REGISTERED (registered) state, and the MME will no longer receive the ATTACHREQUEST (attach request) message of the user. [0003] At present, there are the following methods to deal with abnormal situations that occur during the user attachment process: [0004] 1) Low-level errors [0005] If a low-level error occurs before the UE has received the ATTACH COMPLETE (attach complete) message, the network end will interrupt the attach process, enter the MM-DEREGI STERED state, and will not resend the ATTACH ACCEPT (attach accept) message. If a GUTI (GloballyUnique Temporary Identity, Global Temporary Identity) is newly assigned ...
