Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of system and method for realizing emergency short message business.
Background technology
At the second generation (2 Generation, be called for short 2G), the third generation (3 Generation, abbreviation 3G) in mobile communication network, as global system for mobile communications (Global System for Mobilecommunications, referred to as GSM), Universal Mobile Telecommunications System (Universal MobileTelecommunications System, referred to as UMTS), adopt circuit switching (Circuit Switch, abbreviation CS) mode provides speech business, adopt wireless universal packet switch (General Packet RadioService, abbreviation GPRS) technology provides limited data service, and formed good covering.
Short message service (Short Message Service, referred to as SMS) be a kind of business that GSM/UMTS network provides for user, make user can pass through the message that user equipment (UE) (User Equipment is called for short UE) sent, received finite length.
Short message service need to be disposed Short Message Service Center (SM Service Centre is called for short SMS-SC), and its function is storage, short-message.If GSM/UMTS mobile network supports short message service, network need to be supported to transmit short message between UE and Short Message Service Center SMS-SC.Short message is at (the Mobile Switch Center of mobile switching centre of UE and current access, be called for short MSC) or GPRS supporting node (Serving GPRS Support Node, abbreviation SGSN) (Layer 3 between, to use L3, layer 3) agreement, the access network element MSC/SGSN of network side and follow-up network element are used mobile service part (Mobile Application Part, MAP) agreement to encapsulate.Short message request need to first be routed to the Short Message Service Center SMS SC of the home-operator under the user equipment (UE) of initiating short message, and the SMS SC being belonged to by UE is responsible for storing and being delivered to the target side of short message.
Short message SMS business structure as shown in Figure 1, comprises following network element:
101, subscriber equipment (UserEquipment is called for short UE), for sending and receiving short message;
When user equipment (UE) is initiated short message request, short message request message need to be sent to 102MSC or SGSN, it is the number of UE ownership place Short Message Service Center that short message request message is delivered number.Message body at short message request message comprises that short message points to the information such as message content of the number (being called end number) of target UE, user's input.
102, mobile switching centre's (Mobile Switch Center is called for short MSC), visitor location register (Visitor Location Register is called for short VLR); GPRS supporting node (ServingGPRS Support Node is called for short SGSN);
MSC/SGSN, for receiving the message calling request (L3 message is used in this request) from UE, is translated into MAP message; According to the number of the Short Message Service Center SMS-SC in the user attaching territory in short message request message, this short message request route is returned to the ownership place of this UE;
MSC/SGSN also, for receiving the SMS terminal call request MAP message from network side, is L3 message by MAP message transformation, then is handed down to the UE in its coverage;
In short message service, moving exchanging center MSC is the intercommunication node of user equipment (UE) (CircuitSwitchDomain is called for short CS territory or circuit domain) and network side in CS territory; SGSN is the intercommunication node of UE (Packet Switch Domain, be called for short PS territory) and network side in PS territory, uses GPRS technology.
Visitor location register VLR serves mobile subscriber in its control area, for storing the relevant information that enters registered mobile subscriber in its control area;
103, short message intercommunication moves control switching point (CSP) (SMS Interworking MSC, be called for short SMS-IWMSC), for receiving the short message request from MSC or SGSN, and sends it to local Short Message Service Center SMS SC and processes;
104, Short Message Service Center (SMS Service Center, be called for short SMS-SC), is responsible for receiving the short message request that its contracted user initiates, and resolves MAP message, stores and delivers this short message SMS;
105, (the SMS Gateway Mobile Switch Center of short messaging gateway mobile switching centre, SMS-GMSC), the short message of being responsible for receiving from Short Message Service Center SMS-SC is delivered request, inquiry attaching position register (Home Location Register, abbreviation HLR), short message is delivered to current MSC or the SGSN of called UE;
106, attaching position register (Home Location Register, be called for short HLR), is responsible for the database of mobile subscriber's management, storage the user's that administers subscription data and mobile subscriber's positional information;
107, short message router (SMS Router), the short message route of responsible SMS-IWMSC and target MSC or SGSN.SMS Router is optional function in short message service, and with the present invention without contacting directly, be not described in detail;
108, strengthen Short Message Entity (Enhanced Short Message Entity is called for short ESME), for initiating, receive the entity of SMS in network.Such as manual board or short message platform (being widely used, as message interactive platform, the ballot system of all kinds of TV programme) etc.
Short Message Service Center SMS SC is routed to the short message SMS that strengthens Short Message Entity ESME, do not need through mobile communication network elements such as SMS-GMSC, adopt point-to-point short message (short messagepeer to peer, be called for short SMPP) the multiple open protocol intercommunication such as agreement or Internet protocol (InternetProtocol is called for short IP).This part is generally that relevant technology contents is realized in operator inside, for example, use SMPP agency to carry out protocol conversion and route, and with the present invention without direct correlation, for for simplicity clear, unified representation is ESME here.
Fig. 2 is the flow chart that existing short message service realizes, and has described the entire flow that calling subscriber equipment UE-1 sends SMS message to target UE.For the object being described clearly, this flow process has been described the short message route flow process of calling subscriber equipment UE-1 when roaming state:
Step 201, UE-1 initiate short message request to MSC/SGSN, and called number is the number of the Short Message Service Center SMS-SC of UE-1 ownership place, and the called number of real target UE is encapsulated in the message body inside of short message request;
It is upper that the SMS-SC number of the Short Message Service Center of ownership place can be pre-configured to be in UE, and all short messages that UE-1 initiates all need to use the number of Short Message Service Center SMS-SC as the called number of short message request;
Step 202, MSC/SGSN receive after the short message request from UE-1, because the message from UE-1 is L3 message, conversion need carry on an agreement, by L3 message transformation, be MAP message, according to called number (being the number of Short Message Service Center SMS-SC), the short message intercommunication that this short message request route is returned to the home domain of UE-1 moves control switching point (CSP) SMS-IWMSC;
Step 203, SMS-IWMSC receive after short message request, short message is uploaded to Short Message Service Center SMS-SC and processes;
Step 204-206, Short Message Service Center SMS-SC resolve the short message request message of receiving, by SMS-IWMSC, the network elements such as MSC/SGSN are replied delivery report to UE-1, and notice UE-1 has successfully received short message;
Step 208a, the SMS-GMSC of short messaging gateway mobile switching centre, by inquiry attaching position register HLR, initiate message dilivery to target UE UE; In step 208a, short message is first delivered to the current resident MSC/SGSN of object UE, then by MAP message transformation, is L3 message by MSC/SGSN, and delivers to object UE; For simple flow, consider, do not indicate in the drawings the current resident MSC/SGSN of object UE;
Step 209a-210a, target UE UE are by its resident MSC/SGSN, and SMS-GMSC replys delivery report to SMS-SC;
Step 207b, Short Message Service Center SMS-SC resolve the short message request of receiving, extract and analyze called number, finding called is not mobile terminal, but strengthens Short Message Entity ESME, so Short Message Service Center SMS-SC initiates message dilivery to strengthening Short Message Entity ESME;
Step 208b, enhancing Short Message Entity ESME reply delivery report to Short Message Service Center SMS-SC.
From the existing short message service flow process shown in Fig. 2, can find out, short message service can realize the short message intercommunication between user.But because the destination number of the short message request of initiating from calling subscriber equipment is the number (number of the real called party UE of this short message request is encapsulated in the message body of short message request inside) of SMS-SC of the ownership place of this calling subscriber equipment, so no matter user is in home network, or in roaming network, the resident access network element MSC/SGSN of user that initiates short message request cannot learn the true delivery number of this short message request, this short message request all can first be issued the Short Message Service Center SMS-SC of user ascription area, then after being resolved by Short Message Service Center SMS-SC, to receiving user, deliver again.
Because the application of short message now gets more and more, cellphone subscriber is more and more extensive to the application of short message, increasing to the range of needs of short message.If can complete with short message the urgency traffic of similar urgent call, as used short message service in the situations such as fire alarm, robber and police, first aid, for the people of deaf-mute, the obstacle of speaking or under some special occasions, (when be inconvenient to use telephone call) seems necessary.
If but by current short message mechanism, realize urgency traffic completely, i.e. emergency short message, has following problem and defect:
First, no matter this subscriber equipment is to be positioned at roaming place or ownership place this moment, called number in short message request is the number of the home domain Short Message Service Center configuring on this subscriber equipment, so this request will be routed back the Short Message Service Center of this user ascription area and deal with, so if user roams, the promptness that short message is processed may be had influence on, the demand of urgency traffic cannot be met;
Secondly, general Short Message Service Center need to be served for the user of magnanimity, so short message throughput is huge, Short Message Service Center generally can adopt queuing mechanism, the short message request queue receiving is processed to (as arriving first first treatment mechanism), in this case, greatly affect possibly the promptness that emergency message is processed, may cause serious consequence;
Finally, because emergency numbers is generally universal number, as the numbers such as 119,911, Short Message Service Center, after receiving this type of urgent message, need to be chosen suitable urgent center according to user's current location information and deliver note.If user now initiates emergency short message in visited place, so after the Short Message Service Center of this emergency message route reuse family home domain, Short Message Service Center cannot be learnt the positional information that user is current, thereby cannot deliver note in the urgent center of selecting properly, so cannot be correctly for user provides urgent message service.
Therefore, the urgent message mechanism that this processes with regard to the Short Message Service Center SMS-SC that needs improvement to depend on user attaching network, realize a kind of emergency short message system that can realize fast, accurately deliver and corresponding method, to guarantee real-time and the reliability of urgency traffic.

Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
For guaranteeing the correct user's of processing emergency short message request in time, the invention provides a kind of emergency short message operation system and method for the treatment of emergency short message, by the network element of the current place of user network, process the request of Client-initiated emergency short message, user's emergency short message request is routed to suitable urgent center (Public Safety Answering Point, be called for short PSAP), such as with the urgent center such as the corresponding police office of emergency numbers, fire department, hospital, thereby success provides urgency traffic service to user.
Due to the emergent operation request of support voice mode only of the PSAP in current network, so PSAP need to do to strengthen here, to support the urgency traffic of short message way, be called and strengthen urgent center ePSAP.Such as: use mobile number to do the special number of urgent message; Or use a general short message platform (as the Short Message Entity strengthening, Enhanced Short Message Entity, be called for short ESME) receive all emergency short messages, then by other modes, as the target place of the urgency traffics such as human relay working police office, fire brigade.This part content and the present invention be without contacting directly, so the present invention uses ePSAP (PSAP of enhancing) to express support for the urgent center of emergency short message or the emergency short message treatment system at urgent center.
By drawings and the specific embodiments, the implementation method of emergency short message business is specifically described below.
Fig. 3 is the flow chart that embodiments of the invention one are realized emergency short message business.This embodiment represents the handling process of user equipment (UE)-1 emergency short message when roaming state.Its step is described below:
Step 301, user initiate emergency short message request by user equipment (UE)-1.This flash request is L3 message, and the destination number of L3 message is the number of user attaching territory Short Message Service Center SMS-SC, in L3 message body, has encapsulated the content of emergency numbers and emergency short message;
If it is emergency numbers that UE-1 identifies the called number of Client-initiated short message, UE-1 can increase urgent sign in L3 message header, represents that this message is emergency short message.Wherein, user equipment (UE)-1 identified emergency number can be in the following way:
Pre-configured home domain emergency numbers in user equipment (UE)-1 for example; If or UE-1 is before initiating emergency short message, receives the emergency numbers that current network issues; Or user initiates emergency short message etc. by UE-1 emergency short message interface.The mode by terminal recognition emergency numbers here, is that terminal realizes with content of the present invention without contacting directly, thereby is not limited to above-mentioned several mode.
After the access network element eMSC/eSGSN/VLR of step 302, current network receives emergency short message request, resolve L3 message, according to the called number being encapsulated in L3 message, analyzing this message request is emergency short message request;
EMSC/eSGSN/VLR need to configure the emergency telephone number using with the all-network of its signing roaming agreement, and whether according to configured emergency telephone number, by number analysis, identify this message request is emergency short message request;
Consider the real-time of emergency message, in step 301, subscriber equipment can add urgent sign, consider the emergency numbers of subscriber equipment possibility None-identified user input under roaming situation simultaneously, so possible subscriber equipment does not also know that user has initiated urgent message, so need eMSC/eSGSN according to pre-configured emergency numbers in step 302, judge whether this note request is urgent message.If eMSC/eSGSN/VLR is identified in L3 message header, there is urgent sign, also can judge that this message request is emergency short message.
Step 303, eMSC/eSGSN process emergency short message, and the ePSAP number configuring according to himself is near suitable ePSAP number this emergency short message is selected;
In this embodiment, because urgency traffic is in particular cases non-, for guaranteeing that real-time and position reason (as reported to the police) need to process in visited place, but so the ePSAP of ePSAP visited network herein, this visited network number is configured in eMSC.Described suitable ePSAP number refers to the ePSAP mating with urgency traffic on the one hand, refers to that on the other hand, in the situation that business is mated, MSC, according to user's current location information, carrys out the ePSAP that chosen distance is suitable, and this message request is dealt with.Afterwards, called number is replaced with to the ePSAP number of its configuration, and this message is routed to corresponding ePSAP, complete the delivery of emergency short message; The ePSAP number that is now configured in eMSC/eSGSN is a routable number, such as a phone number urgency traffics such as (special-purpose) police stations.
If also have MSC or SGSN to exist between eMSC/eSGSN and ePSAP, eMSC/eSGSN need to be converted into the message request of L3 MAP message dilivery to the resident MSC of ePSAP or SGSN, by the resident MSC/SGSN of ePSAP, be translated into L3 message again, deliver to ePSAP.
Step 304, ePSAP reply delivery report to eMSC/eSGSN; Delivery report reverse-path is consistent with the path of step 303, but opposite direction;
Step 305, eMSC/eSGSN send delivery report to UE.This step also can be carried out after step 301.
Because urgent central platform or system and short message service center may be proprietary protocols, as SMPP or IP agreement etc., MSC does not possess this ability, so ePSAP number now must be a routable number, such as certain mobile phone dedicated number of in police office etc.
Fig. 4 is the flow chart that embodiments of the invention two are realized emergency short message business.This embodiment represents the handling process of UE-1 emergency short message when roaming state.Its step is described below:
Step 401, user initiate emergency short message request by UE-1.This flash request is L3 message, and the destination number of L3 message is user attaching territory Short Message Service Center SMS-SC number, in L3 message body, has encapsulated the content of emergency numbers and emergency short message;
If it is that emergency numbers is (as pre-configured home domain emergency numbers that UE-1 identifies the called number of Client-initiated short message, if or the emergency numbers that issues in the current network of initiating to receive before emergency short message of UE-1), UE-1 can increase urgent sign in L3 message header, represents that this message is emergency short message.
After step 402, eMSC/eSGSN/VLR receive message request, resolve L3 message, according to the called number being encapsulated in L3 message, analyzing this message request is emergency short message request; EMSC/eSGSN is translated into MAP message subsequently, and inserts the current positional information of UE-1, such as cellID etc.;
EMSC/eSGSN/VLR need to configure the emergency telephone number using with the all-network of its signing roaming agreement, and whether by number analysis, identify this message request is emergency short message request; Consider the situation of roaming, need on eMSC/eSGSN, configure the emergency numbers with the all-network of its signing roaming agreement.If eMSC/eSGSN/VLR is identified in L3 message header, there is urgent sign, also judge that this message request is emergency short message;
According to above-mentioned judgment rule, if the L3 message in eMSC/eSGSN determining step 401 is emergency short message request, eMSC/eSGSN, after being translated into MAP message, adds urgent sign in MAP message header; Because L3 message is only used between eMSC/eSGSN at UE, eMSC/eSGSN generates MAP message continuation delivery after resolving L3 message.Therefore,, if L3 message is not added urgent sign can judge that message request is emergency short message request by eMSC/eSGSN time, in MAP, add urgent sign.
Step 403, eMSC/eSGSN are routed to local SMS-IWMSC by MAP message request;
Step 404, SMS-IWMSC are routed to local SMS-SC by this message request;
It is emergency message request that step 405, SMS-SC judge this message according to the urgent sign in this MAP message, preferentially this message is processed.SMS-SC, according to the UE-1 positional information of carrying in message, selects suitable ePSAP, the called number in message is replaced with to the ePASP number of choosing, and carries out message dilivery;
Step 406-408, SMS SC reply delivery report to UE-1; Delivery report path and step 401,403,404 paths are consistent, opposite direction;
Step 409, SMS-SC issue local SMS-GMSC by this message;
Step 410, SMS-GMSC, according to the called ePSAP number of message, are delivered to corresponding ePSAP by emergency short message, complete the delivery of emergency short message;
In SMS-GMSC and ePSAP, should also have a MSC/SGSN, the message format that its effect is is L3 by MAP message transformation, is delivered to ePSAP.
Step 411-412, ePSAP reply delivery report to SMS SC, delivery report path and step 409,410 consistent, opposite direction;
Fig. 5 is the flow chart that embodiments of the invention two are realized emergency short message business.This embodiment represents the handling process of UE-1 emergency short message when roaming state.Its step is described below:
Step 501, user initiate emergency short message request by UE-1.This flash request is L3 message, and the destination number of L3 message is user attaching territory Short Message Service Center SMS-SC number, in L3 message body, has encapsulated the content of emergency numbers and emergency short message;
If it is that emergency numbers is (as pre-configured home domain emergency numbers that UE-1 identifies the called number of Client-initiated short message, if or UE-1 is before initiating emergency short message, receive the emergency numbers that current network issues), UE-1 can increase urgent sign in L3 message header, represents that this message is emergency short message.
After step 502, eMSC/eSGSN/VLR receive message request, resolve L3 message, according to the called number being encapsulated in L3 message, analyzing this message request is emergency short message request; EMSC/eSGSN is translated into MAP message subsequently, and inserts the current positional information of UE-1, such as cellID etc.;
EMSC/eSGSN/VLR need to configure the emergency telephone number using with the all-network of its signing roaming agreement, and whether by number analysis, identify this message request is emergency short message request; If eMSC/eSGSN/VLR is identified in L3 message header, there is urgent sign, also judge that this message request is emergency short message; According to above-mentioned judgment rule, if the message of eMSC/eSGSN determining step 501 is emergency short message request, eMSC/eSGSN, after being translated into MAP message, adds urgent sign in MAP message header;
Step 503, eMSC/eSGSN are routed to local SMS-IWMSC by MAP message request;
Step 504, SMS-IWMSC are routed to local SMS-SC by this message request;
It is emergency message request that step 505, SMS-SC judge this message according to the urgent sign in this message, preferentially this message is processed.SMS-SC, according to the UE-1 positional information of carrying in message, selects suitable ePSAP, the called number in message is replaced with to the ePASP number of choosing, and carries out message dilivery;
In this embodiment, SMS-SC also may be routed to emergency short message ESME and process, and ESME may be a general classes of messages platform, by this platform, emergency message is handed down to PSAP by multiple means and processes; Here unify ESME/PSAP also referred to as ePSAP;
Step 506-508, Short Message Service Center SMS SC reply delivery report to UE-1; Delivery report path and step 501,503,504 paths are consistent, opposite direction;
Step 509, SMS-SC are delivered to corresponding ESME/ePSAP by emergency short message, complete the delivery of emergency short message;
Step 510, ePSAP reply delivery report to SMS-SC.
In execution mode shown in Fig. 5, SMS-SC both can deliver PSAP by ESME, also can directly be delivered to ePSAP.If what still dispose in network is PSAP (not escalating into ePSAP), may need ESME, because PSAP may not support the urgency traffic of short message way.Two embodiment provide two kinds of modes, and during deployment, which kind of mode operator can select to adopt dispose, and can select flexibly according to concrete network condition.
