Abstract

The invention discloses a warning message ending method and device. After an eNB completes related operations according to kill requests issued by an MME, when nominated disastrous warning messages on broadcasting exist in other regions relative to the MME issuing the kill requests in the eNB, eNB carries cells of regional messages, still broadcasted in the eNB, of nominated disastrous warning messages in the MME response messages. Therefore, the MME is made to find the difference between actual processing and actual needs and then selects subsequent operations or procedures reasonably, and finally the problems that broadcasting conditions of corresponding ETWS messages in the eNB are understood mistakenly by the MME and the ETWS messages cannot be stropped broadcasting timely and effectively in the related regions in eNB are solved effectively.

Description

A kind of warning information ending method and device

Technical field

The present invention relates to the communications field, be specifically related to a kind of warning information ending method and device.

Background technology

At LTE (Long Term Evolution, Long Term Evolution) in system, MME (Mobility Management Entity, Mobility Management Entity) can be according to actual conditions to the eNB (eNodeB that is connected and need to sends a warning message with own built vertical S1, enode b) initiate Write-Replace Warning procedure (writing-replace alarm process), with notice eNB, the UE (User Equipment, subscriber equipment) residing in own affiliated relevant range is carried out to the broadcast of warning information.Here the warning information of indication specially refers to the relevant calamitous warning information of ETWS (Earthquake and Tsunami Warning System, seismic sea wave warning system).ETWS information has the features such as high importance, high-timeliness on processing, to can notify timely and effectively the personnel escape of relevant range before disaster is arrived.Equally, when needs eNB goes off the air ETWS warning information, MME can initiate Kill procedure (terminal procedure) to eNB, to notify eNB to finish ETWS warning information in the broadcast of relevant range.

According to the description of agreement 36.413, when needs eNB goes off the air ETWS warning information, MME can send a KILL REQUEST (ending request) message to eNB, this message has comprised and has required eNB go off the air essential cell Message Identifier (identification of ETWS message) and the Serial Number (sequence number) of ETWS information and the optional cell Warning Area List (alarm zone list) in the ETWS region of need to going off the air.While having carried cell Warning Area List in KILL REQUEST message, eNB can stop the broadcast of corresponding ETWS information in appointed area; While not carrying cell Warning Area List in KILL REQUEST message, eNB can stop the broadcast of corresponding ETWS information in all communities of oneself.36.413 also describe simultaneously, as the response to KILL REQUEST message, eNB can reply a KILL RESPONSE (finishing response) message to MME, and this message is carried essential cell Message Identifier (identification of ETWS message) and Serial Number (sequence number) and optional cell Broadcast Cancelled Area List (ETWS information broadcast is cancelled successful region).While having carried cell Broadcast Cancelled Area List in KILL RESPONSE message, represent that eNB has successfully cancelled Message Identifier and the specified ETWS message of Serial Number; While not carrying cell Broadcast Cancelled Area List in KILL RESPONSE message, be illustrated in eNB, do not have the specified ETWS message of broadcasting of Message Identifier and Serial Number to stop; When some region A are included in the cell Warning Area List of KILL REQUEST message and are not included in the cell Broadcast Cancelled Area List of KILL RESPONSE message, be illustrated in the A of this region, do not have the specified ETWS message of broadcasting of Message Identifier and Serial Number to stop.

When practical application, in eNB, the specified ETWS message of Message Identifier and Serial Number is just broadcasted in the A of region, but but received when requirement that MME issues stops the KILL REQUEST message of this ETWS information in the B of region, according to agreement, now eNB can only reply the KILL RESPONSE message of not carrying cell Broadcast Cancelled Area List to MME, simultaneously according to agreement, MME can think does not have Message Identifier and the specified ETWS message of broadcasting of Serial Number in eNB, this is obviously problematic.And, if MME has carried mistakenly the information of region B when the ETWS broadcast that needs stop area A in KILL REQUEST message, according to the processing of agreement and understanding, will cause MME to think the corresponding ETWS information of not broadcasting in corresponding eNB, this can make the ETWS broadcast message of region A in eNB be stopped timely and effectively, this can not meet actual demand, also can cause the mistake of ETWS information broadcasting to be sent out, thereby bring panic result to user.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of warning information ending method and device, make MME can effectively find the true difference of processing with actual demand, effectively to solve the broadcast situation of ETWS information in eNB by MME error understanding and the problem that can not go off the air timely and effectively in relevant range in eNB.

For achieving the above object, technical scheme of the present invention is achieved in that

An ending method, the ending request that enode b eNB issues according to Mobility Management Entity MME completes after associative operation, and described method comprises:

In eNB, with respect to MME, issue while still there is the calamitous warning information of appointment of broadcasting in other region of ending request, eNB carries the cell of specifying the area information that calamitous warning information still broadcasts in eNB in the response message to MME.

The method of the ending request complete operation that eNB issues according to MME is:

ENB, according to the request of MME, finishes the broadcast of calamitous warning information in respective regions.

Described region is alarm region, corresponding to cell information, tracing area identification TAI information or emergency region information.

Described calamitous warning information is seismic sea wave warning system ETWS information.

Described ending request is ending request message KILL REQUEST, and described response message is for finishing response message KILL RESPONSE.

Finish a device, in the ending request issuing according to MME, complete after associative operation, described device is used for:

In this device, with respect to MME, issue while still there is the calamitous warning information of appointment of broadcasting in other region of ending request, in the response message to MME, carry the cell of specifying the area information that calamitous warning information still broadcasts in this device.

Described device when the ending request complete operation issuing according to MME, for:

According to the request of MME, finish the broadcast of calamitous warning information in respective regions.

Described region is alarm region, corresponding to cell information, TAI information or emergency region information.

Described calamitous warning information is ETWS information.

Described device is eNB.

The inventive method and device, after the ending request complete operation issuing according to MME at eNB, in eNB, with respect to MME, issue while still there is the calamitous warning information of appointment of broadcasting in other region of ending request, eNB carries the cell of specifying the area information that calamitous warning information still broadcasts in eNB in the response message to MME.Thereby make MME can effectively find the difference of true processing and actual demand, and then reasonably select follow-up operation or flow process, finally efficiently solve the broadcast situation of corresponding ETWS information in eNB and by MME error understanding with in eNB, in relevant range, can not stop timely and effectively the problem being broadcasted.
