Embodiment
For enabling above-mentioned purpose, the feature and advantage of the application more become apparent, below in conjunction with the drawings and specific embodiments, the application is described in further detail.
The application proposes the processing method that a kind of NAS of improving can not transmit instruction, makes MME after the message instruction receiving eNB, can carry out different operations according to different instructions.The method can improve flow processing, reduces Signalling exchange, improves network performance.
Below by embodiment, the realization flow of method described in the application is described in detail.
In prior art, NAS can not transmission indicating information message structure definition as shown in the 9.1.7.4 chapters and sections of 3GPPTS36.413V10.3.0 agreement, in table 1:
Table 1NAS can not the message structure of transmission indicating information
ENB issues the NAS of MME can not in transmission indicating information, and the NAS message that can not pass to UE is included in NAS-PDU, and is included in Cause by suitable cause value, and cause value may be following several:
S1 handover trigger (S1intrasystemHandoverTriggered) in system;
S1 handover trigger (S1intersystemHandoverTriggered) between system;
X2 handover trigger (X2HandoverTriggered);
At wave point failure (FailureintheRadioInterfaceProcedure) etc.
First the embodiment of the present application can not the different cause values of transmission indicating information classify to NAS, reason can be divided into: switch relevant reason and rrc layer disconnects or the more weak failure caused of signal.Further, different processing methods is proposed to different cause values.
In practical application, rrc layer disconnects or signal is more weak causes that cannot to transmit this situation of NAS message more, first introduces the processing method for this situation below.
1, the reason that can not transmit of NAS: rrc layer disconnect or signal more weak
If the signal between eNB and UE is more weak, or RRC disconnects, eNB, owing to NAS message can not be sent to UE, can send the cause value of non-switching reason, as " at wave point failure (FailureintheRadioInterfaceProcedure) " to MME.
In this case, the embodiment of the present application can not increase information element (IE)---the stand-by period (Timetowait) that one identifies delay time in transmission indicating information at NAS, and existence is optional, specifically as shown in table 2:
Table 2 increases the NAS after information element can not the message structure of transmission indicating information
ENB, when confirmation UE does not switch, can carry the stand-by period (Timetowait) to MME.During this period of time, eNB can ceaselessly paging UE.MME does not receive response within the stand-by period, then MME thinks that NAS message can not pass to UE, former NAS procedure failure.
Flow process below by Fig. 2 and Fig. 3 describes the processing method of eNB and the processing method of MME respectively in detail.
With reference to Fig. 2, be the eNB process flow figure that a kind of NAS described in the embodiment of the present application can not transmit instruction.
Step 201, eNB determines the connection failure with UE, then will issue the NAS message buffer memory of this UE, and send to MME the NAS being added with the stand-by period can not transmission indicating information;
First, eNB will determine whether the reason that NAS can not transmit is non-switching reason, if RRC connection signal is more weak or RRC connects the situation that there is not (namely rrc layer connects disconnection), eNB is by this NAS-PDU of buffer memory (NAS message), and can not Indication message be transmitted to MME transmission NAS, cause value is " at wave point failure (FailureintheRadioInterfaceProcedure) ".Further, specify a stand-by period (Timetowait) by eNB, be carried to MME in the message.
Step 202, within the described stand-by period, described eNB attempts re-establishing with described UE being connected;
Wherein, described eNB attempts re-establishing with described UE the process be connected and specifically comprises following sub-step:
Sub-step 1, described eNB initiates beep-page message to described UE, adds the information element not needing service request to indicate in described beep-page message;
Sub-step 2, after described UE receives described beep-page message, directly re-establishes RRC with described eNB without service request and is connected.
The beep-page message that eNB issues UE is broadcast, if do not receive the response of UE, eNB can ceaselessly paging within the stand-by period.
Preferably, issue at ENB in paging (Paging) message of UE to increase does not need service request to indicate (NoNeed-serviceRequest-Indication) information element to the embodiment of the present application.
Such as, in agreement 3GPPTS36.331V10.3.0, in the Paging message of definition, increase information element (IE)---do not need service request to indicate (NoNeed-serviceRequest-Indication), as follows:
Pagingmessage (beep-page message) after improvement is:
Wherein,
Table 3
If carrying in the beep-page message (Pagingmessage) that eNB sends does not need service request to indicate (NoNeed-serviceRequest-Indication), UE after receiving that message, initiate RRC connection establishment process, and do not need to initiate service request procedure.Namely UE can omit the process initiating service request, therefore further reduces Signalling exchange, improves network performance.
If within the time interval of stand-by period (Timetowait), eNB can paging to UE, the success of RRC connection establishment namely between eNB and UE, then perform step 203 and 204.
Step 203, when in the described stand-by period during successful connection, the NAS message of buffer memory is issued corresponding UE by described eNB;
Concrete, the NAS-PDU of buffering can be sent to UE by DLinformationtransfer (downstream message transmission) message by eNB.
Step 204, described eNB sends successful NAS to MME transmission instruction NAS can not transmission indicating information.
Concrete, eNB sends instruction NAS send successful information by not carrying in transmission indicating information at NAS with under type:
ENB sends NAS to MME can not transmit Indication message, and cause value is " Unspecified ", represents that NAS sends successfully, and does not carry the stand-by period (Timetowait) information element.This cause value is that the NAS of " Unspecified " can not transmit Indication message and is used for informing that the former NAS message of MME has sent successfully, and flow process can proceed.
Correspondingly, if within the time interval of stand-by period (Timetowait), eNB still can not paging to UE, the failure of RRC connection establishment namely between eNB and UE, then Fig. 2 flow process can also comprise the following steps:
Step 205, connection failure, then termination process after the described stand-by period terminates.
If within the stand-by period, limited number of time RRC between eNB and UE connects all failed, although or in the unsuccessful situation of connection, eNB can unlimited paging UE, be above the described stand-by period still in ceaselessly paging, so, eNB can not transmission indicating information by no longer sending NAS to MME.
For the process of the eNB shown in above-mentioned Fig. 2, the respective handling of MME as shown in Figure 3.
With reference to Fig. 3, be the MME process flow figure that a kind of NAS described in the embodiment of the present application can not transmit instruction.
Step 301, MME receives from eNB the NAS being added with the stand-by period can not transmission indicating information;
Namely the NAS that MME receives can not transmit in Indication message, cause value is " at wave point failure (FailureintheRadioInterfaceProcedure) ", further, also added a stand-by period of being specified by eNB (Timetowait) in this message.
Step 302, described MME starting duration equals the timer of described stand-by period;
MME receives after above-mentioned NAS can not transmit Indication message, and can start a timer and start timing, the duration of this timer equals the described stand-by period.
Step 303, within the described stand-by period, when described MME from described eNB receive instruction NAS send successful NAS can not transmission indicating information time, stop described timer.
If namely MME within the described stand-by period, receive eNB can not transmission indicating information in the NAS that the cause value that step 204 sends is " Unspecified ", then stop the timing of described timer, represent that NAS sends successfully, flow process can continue.
But if after described timer timing terminates, MME does not still receive NAS that cause value is " Unspecified " can not transmission indicating information, then Fig. 3 flow process can also comprise the following steps:
Step 304, after the described stand-by period terminates, when described MME not from described eNB receive instruction NAS send successful NAS can not transmission indicating information time, described timer expiry, termination process.
Namely MME can think that UE is unreachable, termination process, flow process failure.
The flow process of above-mentioned Fig. 2 and Fig. 3 is combined, if within the time interval of stand-by period (Timetowait), eNB can paging to UE, then eNB and MME can according to the flow performing of Fig. 4.
With reference to Fig. 4, it is eNB and the MME process chart that a kind of NAS described in the embodiment of the present application can not transmit instruction.
Step 401, eNB sends to MME the NAS being added with the stand-by period can not transmission indicating information;
If eNB determines that UE does not switch, but can not determine and the NAS in former flow process transmission indicating information can not can be sent to UE, so, eNB is by this NAS-PDU of buffer memory, and send NAS to MME can not transmission indicating information, cause value be " at wave point unsuccessfully (FailureintheRadioInterfaceProcedure) ".Further, specify a stand-by period (Timetowait) by eNB, be carried to MME in the message.
After MME receives message, starting duration equals the timer of stand-by period (Timetowait).
Step 402, eNB initiates paging to UE;
Preferably, the information element not needing service request to indicate is added in described beep-page message;
Step 403, re-establishes RRC and connects between eNB and UE;
UE, after receiving this beep-page message, initiates RRC connection establishment process, and does not need to initiate service request procedure;
Step 404, the NAS-PDU of buffer memory is sent to UE by DLinformationtransfer message by eNB;
Step 405, eNB sends NAS to MME can not transmit Indication message, and cause value is " Unspecified ", does not carry the stand-by period (Timetowait) information element.This message is used for informing that former NAS message has sent successfully, and flow process can proceed.
After MME receives this message, stop the timer in step 401.
If within the time interval of stand-by period (Timetowait), eNB can not paging to UE, then MME is after timer timing terminates, and thinks that UE is unreachable, termination process.
In sum, for the cause value of eNB and UE connection failure, eNB can not add the message element that identifies delay time in transmission indicating information at NAS, and specify a stand-by period in this message element, MME starting duration equals the timer of described stand-by period simultaneously.Within waiting time, eNB can re-establish with UE and be connected, if successful connection, then the NAS message of buffer memory can be issued UE by eNB again, and flow process continues; If connection failure or time-out, MME re-recognizes for NAS message can not be delivered to UE, flow process failure.The process of NAS message transmission flow that the processing policy of described time delay is perfect, can improve the success rate of flow process, reduces Signalling exchange, promotes network performance.
2, the reason that can not transmit of NAS: switch relevant reason
If eNB determines that cell merge occurs UE, then sending to MME the NAS not adding the stand-by period can not transmission indicating information, and this NAS can not carry the cause value that UE switches in transmission indicating information, and reason may be:
S1 handover trigger (S1intrasystemHandoverTriggered) in system;
S1 handover trigger (S1intersystemHandoverTriggered) between system;
X2 handover trigger (X2HandoverTriggered);
NAS can not transmission indicating information carry switch relevant cause value time, eNB does not need to carry the stand-by period (Timetowait) to MME.Concrete message structure can see table 1.
Correspondingly, MME receives from eNB the NAS not adding the stand-by period can not after transmission indicating information, and this NAS can not carry the cause value that UE switches in transmission indicating information; Described MME etc. are to be switched complete after, can again to switch after eNB send NAS message.This NAS message is sent to the corresponding UE after cell merge by eNB after switching again.
