Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of information getting method and device.
Background technology
Subscriber equipment (UE; User Equipment) sign is divided into several kinds: IMSI International Mobile Subscriber Identity (IMSI; International Mobile Subscriber Identity), International Mobile Station Equipment Identification (IMEI; InternationalMobile Equipment Identity), International Mobile Station Equipment Identification software version (IMEISV; InternationalMobile Subscriber Identity Software Version), circuit domain user temporary identifier (TMSI; Temp Mobile Subscriber Identity) (CS is professional)/packet domain user temporary identifier (P-TMSI, Packet Temp Mobile Subscriber Identity) (PS is professional).Wherein, IMSI is the sign of subscriber identification module (SIM, Subscriber Identity Module) card, and IMEI and IMEISV are unique device identifications of UE; TMSI (CS is professional)/P-TMSI (PS is professional) is the temporary mark that core net (CN, Central Network) is distributed to UE.
When UE inserts the network of certain lane place for the first time; That use is IMSI, when inserting once more in this lane place, use be temporary sign TMSI (CS is professional)/P-TMSI (PS is professional); UE seldom uses the IMEI access network, only if can use IMEI when not having SIM and placement of emergency calls.Therefore the IMSI of UE, TMSI (CS is professional)/P-TMSI (PS is professional); Access Network can both obtain in access procedure; Wherein, From public ID (COMMON ID) message that CN issues, obtain IMSI, and radio network controller (RNC, Radio Network Controller) generally obtains IMEI and IMEISV less than UE.
Can know by the normal signaling tracing flow process that inserts of UE; UE at first sends initial direct-sending (INITIALDIRECT TRANSFER) message and gives RNC; Set up SCCP (SCCP through RNC and CN; Signalling Connection Control Part) link, RNC sends initial UE information (INITIAL UE MESSAGE) to CN, and the whole connection between UE and the CN has at this moment just been accomplished.At this moment can carry out alternately through non-access layer information between UE and the CN.So-called non-access layer information is exactly the protocol layer on the Access Layer, and Access Network is transparent transmission only, has only UE and CN to discern and to handle.After the authentication process (AUTHENTICATION) of Non-Access Stratum was accomplished, CN sent COMMON ID message to RNC, and that carry is IMSI or the IMEISV of UE.The process of back is safe mode (SECURITY MODE) control, is used for message is carried out integrity protection and encryption.
After safe mode control; CN has initiated Non-Access Stratum identification request (IDENTITYREQUEST) message; The IMEI of acquisition request UE; RNC passes through UE with IDENTITY REQUEST message, and UE replys identification response (IDENTITY RESPONSE) message, and RNC passes through CN to IDENTITY RESPONSE message again.Therefore, RNC is actual and do not know mutual what information between CN and the UE in this process.
Because IMEI and IMEISV are the unique identifications of UE equipment, the IMEI scope of each UE producer has nothing in common with each other, and can distinguish through IMEI is the UE of which producer.Operator pays special attention to critical sales index (KPI, the Key Performance Indication) index analysis of each UE producer product based on IMEI, still, can't realize analyzing based on the KPI of IMEI in the RNC side.
Prior art depends on the CN side and initiates IDENTITY REQUEST message process, and each CN producer realizes difference, and the function of not supporting to initiate IDENTITY REQUEST message that has causes the CN side also possibly can't realize analyzing based on the KPI of IMEI.
In sum, prior art RNC can't obtain the sign such as IMEI, IMEISV of UE.

The structural representation of a kind of radio network controller (RNC) that Fig. 2 provides for the embodiment of the invention.
Embodiment
The embodiment of the invention provides a kind of information getting method and device, obtains signs such as the IMEI of UE, IMEISV in order to realize RNC.
Below in conjunction with accompanying drawing the technical scheme that the embodiment of the invention provides is described.
Referring to Fig. 1, a kind of information getting method that the embodiment of the invention provides comprises step:
S101, radio network controller (RNC) receive identification response (IDENTITYRESPONSE) message from user equipment (UE).
S102, RNC obtain the identification information of UE through IDENTITY RESPONSE message is resolved.
Preferably, RNC is through resolving IDENTITY RESPONSE message, and the step of obtaining the identification information of UE comprises:
RNC resolves IDENTITY RESPONSE message;
When comprising the identification information of UE in the IDENTITY RESPONSE message, then RNC obtains the identification information of this UE;
When not comprising the identification information of UE in the IDENTITY RESPONSE message, RNC sends identification request IDENTITY REQUEST message, the identification information of acquisition request UE to UE.
Preferably, when not comprising the identification information of UE in the IDENTITY RESPONSE message,
RNC sends IDENTITYREQUEST message to UE after receiving initial direct-sending (INITIAL DIRECT TRANSFER) message; Perhaps,
RNC sends IDENTITY REQUEST message to UE after the SCCP that receives core net (CN) transmission sets up link completion message; Perhaps,
RNC sends IDENTITY REQUEST message to UE send safe mode completion (SECURITY MODE COMPLETE) message to CN after.
Preferably, when not comprising the identification information of UE in the IDENTITY RESPONSE message, RNC is after UE sends identification request (IDENTITY REQUEST) message, and this method also comprises:
RNC receives the IDENTITY RESPONSE message that UE returns, and therefrom obtains the identification information of UE;
The sequence number of the IDENTITY RESPONSE message that RNC returns this UE sends to core net CN.
Preferably, RNC is through empty (MM NULL, the Mobile Management Null) message of mobile management, and the sequence number of the IDENTITY RESPONSE message that UE is returned sends to CN.
Preferably, RNC resolves the identification information of the UE of acquisition to IDENTITY RESPONSE message, comprises IMEI and/or the IMEISV of UE.
That is to say; In the embodiment of the invention; RNC can be in the access procedure of UE, and simulated tissue sends IDENTITY REQUEST message to UE, and request UE reports identification informations such as IMEI or IMEISV; Concrete which type of identification information of request can be indicated in IDENTITY REQUEST message.Thereby RNC resolves after receiving the IDENTITY RESPONSE message of UE, can obtain the sign of UE, needn't depend on CN again and initiate IDENTITY REQUEST process.
Provide detailed explaining below.
The scheme that the embodiment of the invention provides comprises two part and parcels:
First, i.e. RNC simulation CN sends the opportunity of IDENTITY REQUEST message.
Because RNC is mutual through simulation non-access layer information and UE; Might intersect with other Non-Access Stratum processes; Thereby produce certain problem, and the realization of each UE and CN producer has nothing in common with each other, so the embodiment of the invention provides several kinds of transmission opportunitys of IDENTITY REQUEST message; According to the realization of different UEs and CN, select different transmission opportunitys.
For normal access procedure:
First kind of transmission opportunity: RNC sends IDENTITY REQUEST message after receiving INITIAL DIRECT TRANSFER message.
This kind transmission be opportunity RNC after receiving the UE initial direct-sending message, set up before the SCCP link, send IDENTITYREQUEST message.At this moment UE does not also connect with CN, so the flow process of RNC simulation CN transmission IDENTITY REQUEST message can not conflicted with normal non-access layer information flow process generation.
Second kind of transmission opportunity: RNC sets up after link accomplishes message at the SCCP that receives CN, sends IDENTITY REQUEST message.
This kind transmission opportunity is to build up at the SCCP link; Can guarantee that RNC is after receiving the IDENTITY RESPONSE message of UE; Sequence number that needn't buffer memory IDENTITY RESPONSE message that is to say, not buffer memory MM NULL message; Can directly generate MM NULL message, and send to CN.Therefore, processing is simpler.
The third transmission opportunity: RNC sends IDENTITY REQUEST message send SECURITY MODE COMPLETE message to CN after.
That is to say that obtained through IDENTITY REQUEST process at CN under the situation of IMEI or IMEISV of UE, RNC can no longer initiate the query script of IMEI or IMEISV, avoid repeating obtaining the situation of IMEI or the IMEISV of UE, saved time delay.Being this kind transmission opportunity, is RNC confirming that CN does not obtain through IDENTITY REQUEST process under the situation of IMEI or IMEISV of UE, sends IDENTITY REQUEST message, obtains IMEI or the IMEISV of UE.
Second portion is for repositioning process.
RNC is after sending reorientation completion message to CN, simulation is sent the MMNULL message of the correct sequence number of carrying up non-access layer information and given CN.
Under the normal condition; The message in mutual circuit switching (CS) territory between UE and the CN; Each bar upstream message all can be carried a sequence number (sequence number), and the sequence number of each bar upstream message should be continuous, this sequence number of CN meeting verification; If discontinuous, will influence the processing of follow-up message flow.
In 24.007, be described for the sequence number sequence number that comprises in the information type (Message Type), the description of sequence number wherein defines in order to handle repetition message.For the network more than the R99, this value should be upstream message of the every transmission of UE, all corresponding sequence number is added 1, and mould 4 then, and promptly sequence number can be 0,1,2,3, is 3 to the maximum, to continuing since 0 value after 3 again.
On the basis of a upstream message in this UE transmission, do not add 1 if the CN verification goes out the sequence number of the upstream message of UE transmission, will abandon this message, disregard, thereby produce mistake.Therefore, the embodiment of the invention just needs RNC that the sequence number that UE replies to the IDENTITY RESPONSE message of RNC is sent to CN.
MM NULL message between UE and the CN can be accomplished this function, and this message body is empty, only carries the sequence number of IDENTITYRESPONSE message.
Therefore; At RNC when the IDENTITY REQUEST message in CS territory is sent in UE simulation; UE has replied IDENTITY RESPONSE message; RNC comes out the sequence number intercepting in this message, through MM NULL message this sequence number is sent to CN, so just can not cause the problem of the upstream message sequence number failure of CN verification UE owing to the non-access layer information intersection.
Introduce the device that the embodiment of the invention provides below.
Referring to Fig. 2, a kind of radio network controller (RNC) that the embodiment of the invention provides comprises:
Identification response message receiving element 101 is used to receive the identification response IDENTITY RESPONSE message from user equipment (UE).

Preferably, UE sign acquiring unit 102 comprises:
Identification request message transmitting element 202 is used for the triggering according to resolution unit 201, sends identification request IDENTITY REQUEST message, the identification information of acquisition request UE to UE.
Preferably, identification request message transmitting element 202,
After RNC receives initial direct-sending INITIAL DIRECT TRANSFER message, send IDENTITY REQUEST message to said UE; Perhaps,
After RNC receives that the SCCP of core net CN transmission sets up link completion message, send IDENTITY REQUEST message to said UE; Perhaps,
After CN sends safe mode completion SECURITY MODE COMPLETE message, send IDENTITY REQUEST message at RNC to said UE.
Preferably, this RNC also comprises:
Identification response message sequence number notification unit 103 is used for after identification response message receiving element 101 receives the IDENTITY RESPONSE message that UE returns, and the sequence number with this IDENTITY RESPONSE message sends to core net CN.
