Description

A kind of route addressing method of note and system

Technical field

The present invention relates to the mobile communication technology field, relate in particular to a kind of routing addressing technology of note.

Background technology

At present, the application of short message service in the cellular network in CS (circuit) territory is very successful.It is a kind of in the method for transmitting the message with a certain size between the terminal or between terminal and the network entity that described short message service provides.And described short message service is realized note forwarding, storage, delayed delivery and other value-added services by introducing a kind of network entity that is called as sms center.Simultaneously, GSM/UMTS (global system for mobile communications/universal mobile telecommunications system) PLMN (public land mobile net network) needs to support the forwarding capability of note between sms center and terminal.

IMS (IP Multimedia Subsystem, IP Multimedia System) was introduced in the 3GPP R5 stage, was a subsystem that is positioned on the existing network packet domain.This subsystem adopts packet domain, for the bearer path of its upper strata control signaling and media delivery is introduced SIP (Session Initial Protocol, Session initiation Protocol) agreement is as professional control protocol, and utilize simple, easy expansion, the media combination characteristics easily of SIP, by business control is separated with carrying control, provide abundant multimedia service.

The network integration scheme of IMS can make operator provide identical business for fixing with the mobile subscriber based on unified core network.For the core net of fixed network and mobile network and the network architecture of depositing, IMS not only can reduce the complexity of network configuration, also can reduce the operation and the maintenance cost of network.

Because the successful Application of short message service in existing cellular system, and the IMS that is independent of the fusion of Access Network is a network development in future direction, so 3GPP goes in considering the IP that short message service expands to non-cellular network connected.For this reason, 3GPP has defined a cover network architecture and has supported this expansion, and the described network architecture as shown in Figure 1.Each network entity function specifically comprises among Fig. 1:

SME: i.e. Short Message Entity (Short Messaging Entity), this entity can receive or improve short message, and it is positioned at fixed line system, mobile base station or other service centres;

SMSC: i.e. SMS service center (Short Message Service Center), this entity are responsible between base station and SME relaying, storage or are transmitted short message; ME (Mobile Equipment, travelling carriage) can transmit from travelling carriage or towards the short message of travelling carriage, agreement is called SMTP (Short Message Transmission Protocol, note host-host protocol) to the agreement of SMSC;

SMS-IWMSC/SMS-GMSC: be respectively the entry gateway of SMSC and export gateway, this entity receives the short message that is sent by SMSC, and by SMS-GMSC to HLR (Home LocationRegister, attaching position register) inquiry routing iinformation, and note is sent to the switching center of base station, recipient place, in existing network, SMS-GMSC, SMS-IWSMSC generally close and establish;

OCS: i.e. Online Charging System (Online Charging System), AS mail to OCS by Rf interface with charge information when this entity adopted online charging;

CGF/CDF: i.e. offline charging (Charging Gateway Functionality) entity, when offline charging, AS mails to CGF by the Ro reference point with charge information; At Rf and Ro interface, AS all uses the ACR message of DIAMETER agreement to send charge information to OCS or CGF, and the ACA message of application DIAMETER agreement is replied from OCS or CGF reception;

IP-SM-GW:IP Short Message Service Gateway, this entity are used to provide the IWF that transmits note between UE and the GSM/UMTS network, can serve as the IP-SM-GW entity with the AS in IMS territory;

HSS/HLR: home signature user server/attaching position register, be the location register unit of home domain, this entity is used to the SMS business that routing function is provided.System is in termination MT (downlink short message, promptly arrive callee's note by SMSC) time, send route request information to HLR/HSS by SMS-GMSC, if UE (User Equipment, subscriber equipment) previous address of registering IP-SM-GW by registration then needs the address of the E.164 form of IP-SM-GW is returned to SMS-GMSC in route response message.

Based on the network architecture as shown in Figure 1, prior art provides two kinds of technical schemes at the routing procedure in the termination note process.

At first, the register flow path in conjunction with Fig. 2 illustrates IMS territory user in the prior art scheme one comprises:

Step 21, UE initiate the normal registration/weight register flow path in the IMS territory;

Step 22, S-CSCF (Serving-CSCF, serving CSCF) check triggering rule, find the address of IP-SM-GW, trigger the third-party registration process;

The IMS triggering rule that described triggering rule is contracted for the user; Third party described herein is IP-SM-GW or HSS/HLR.

After step 23, IP-SM-GW receive the registration message that S-CSCF sends, the address of storage S-CSCF;

Step 24, IP-SM-GW are initiated to the registering flow path of HSS/HLR, promptly send registration MAP-Register message to HSS/HLR;

The E.164 address information of step 25, HSS/HLR storing IP-SM-GW is returned the registration response, promptly returns MAP-Register Rsp message;

After step 26, IP-SM-GW receive described response message, return the 200OK response message to S-CSCF;

Step 27, S-CSCF continue to return the 200OK response message to UE after receiving described 200OK response message.

Wherein, described 200OK if the return state value is, shows then that state is normal for the state value of response at 200 o'clock.

Above-mentioned is the user registration course in IMS territory, under the prerequisite of user registration success, promptly in HSS/HLR, stored user's relative address information after, like this, during note, system just can finish the routing procedure to the user in termination.

The transmission flow of MT note in the prior art scheme one is described in conjunction with Fig. 3 below again.

Step 31, UE are registered to S-CSCF by the IMS register flow path, and have carried out the said short message register flow path;

Step 32, SMSC transmit SMS message and give SMS-GMSC;

After step 33, SMS-GMSC receive described message, send route request information Route Req to HLR/HSS, comprise an indication in this message, described indication is used to indicate that SMS-GMSC supports the IP message route;

After step 34, HSS/HLR receive described route request information, return route response message Route Rsp, carry the E.164 address of the IP-SM-GW that registers when the user registers in this message to SMS-GMSC;

After step 35, SMS-GMSC receive described response message, send forward direction note FORWARD_SMS, carry the MSISDN (mobile subscriber number) of UE in this note to IP-SM-GW;

After step 36, IP-SM-GW receive described note, then convert described MSISDN to TelUrl, and find corresponding S-CSCF address according to this TelUrl;

Described TelUrl (phone URL(uniform resource locator)) represents traditional E.164 number with the grammer of URL, is used to identify the resource that has taken certain telephone number.

Step 37, IP-SM-GW send to SMS to S-CSCF according to the S-CSCF address of determining;

Step 38, S-CSCF transmit sip message SIP MESSAGE and give UE;

Step 39, UE return the 200OK response to S-CSCF after receiving this SIP MESSAGE;

Step 310, S-CSCF send 200OK to IP-SM-GW after receiving above-mentioned 200 OK response;

Step 311, UE send delivery report Deliver Report to S-CSCF by SIP MESSAGE;

After step 312, S-CSCF receive above-mentioned delivery report, transmit SIPMESSAGE according to filtering rule and give IP-SM-GW;

The IMS filtering rule that described filtering rule is contracted for the user.

Step 313, IP-SM-GW send delivery report to SMS-GMSC after receiving described SIP MESSAGE;

After step 314, SMS-GMSC receive the delivery report of IP-SM-GW transmission, send delivery report state Deliver Report Status to HLR/HSS;

Step 315, SMS-GMSC send delivery report again to SMSC;

Step 316, IP-SM-GW send the 200OK response to S-CSCF;

After step 317, S-CSCF receive the response of IP-SM-GW transmission, send the 200OK response to UE, promptly the MT note sends successfully.

By foregoing description as can be seen,, need in registration process, realize the enrollment process of two links for realizing the transmission of downlink short message: the one, S-CSCF is to the enrollment process of IP-SM-GW; The 2nd, IP-SM-GW is to the enrollment process of HSS/HLR.If the user does not register, the enrollment process of so above-mentioned two links will can not be performed.If do not carry out above-mentioned two enrollment process in the network, then system also just can't carry out route to non-registered users in the termination note, and at this moment, the transmission of downlink short message also just can't realize.For example, the PSI (public user identity) in the IMS territory promptly belongs to the non-registered users that need not to register when using.

A kind of PSI of providing AS is provided called addressing method in the prior art, and this method mainly comprises following several concrete implementation:

1, direct addressin method:

Go up the AS address that directly inquiry obtains called PSI by I-CSCF (Interrogating-CSCF, inquiry CSCF) to HSS/HLR, be routed directly to the AS at PSI place.

2, indirect addressing method:

Obtain earlier the address of a S-CSCF by I-CSCF to HSS/HLR, note is issued S-CSCF after, be routed to the AS at called PSI place according to filtering rule by S-CSCF.

3, DNS (Domain Name Server, name server) method for routing:

Safeguard the tabulation of institute's support region/network name by I-CSCF, after I-CSCF receives note, whether corresponding contents in the described tabulation of the network title of called PSI correspondence and its maintenance is mated, if coupling then arrive DNS and inquires about acquisition AS address.

In the called addressing method of above-mentioned PSI AS, the routing addressing process of described PSI place AS when prior art is mainly considered user conversation, and do not have to consider in the CS territory under the situation of the note intercommunication in IMS territory, send the process of note by the UE in CS territory to the PSI in IMS territory.

Simultaneously, prior art also can't realize being routed to the UE process that the callee is the signatory unregistered service in IMS territory from the note in CS territory.

Embodiment

Relevant introduction from background technology as can be known, the user need register in the IMS territory, the address of recording user service processing node in IP-SM-GW, so that the registered user as the callee is carried out routing addressing during note in termination, and this user of short message serving the most at last.

At some in particular cases, the callee may be the unregistered sign in IMS territory, UE as public service identity or signatory unregistered service, wherein, described public service identity is often provided by supplier, and described public service identity does not have (need not) registration process in the IMS territory, its service processing node is the application server at described public service identity place, the present invention promptly is primarily aimed at the unregistered sign for the IMS territory as the callee, when the termination note, provide the implementation procedure that the application server address to the unregistered sign place in IMS territory carries out addressing, thereby realize the process of note intercommunication of the unregistered sign in CS territory user and IMS territory.

The present invention mainly realizes by following steps:

Step 1, SMS-GMSC receive after SMSC sends to the note of unregistered sign in IMS territory, the address that obtains the corresponding IP-SM-GW of unregistered sign to home domain location register unit, and described note sent to this IP-SM-GW;

After step 2, described IP-SM-GW receive described note, the AS in the IMS territory at described unregistered sign place is carried out addressing, and described note is forwarded to this AS.

The addressing process that provides by the invention described above can expand to short message service the unregistered sign in IMS territory from CS territory and IMS territory.

Below to realizing that above-mentioned two main processes of the present invention are further elaborated.

The present invention has provided three kinds of implementation methods at step 1, is respectively:

Method 11: the corresponding relation that on HSS/HLR, sets in advance unregistered sign and IP-SM-GW address, when SMS-GMSC when HSS/HLR sends routing iinformation request to the corresponding IP Short Message Service Gateway IP-SM-GW address of unregistered sign, return SMS-GMSC by HSS/HLR according to the IP-SM-GW address that described corresponding relation will be provided with;

Specific implementation process can be:

Step a1, on HSS/HLR, set in advance the E.164 address of the corresponding IP-SM-GW of unregistered sign;

Step a2, SMSC send note (Short Message) to SMS-GMSC;

Step a3, SMS-GMSC send route requests (Route Req) message to HSS/HLR, to obtain routing iinformation;

Step a4, HSS/HLR send route response (Route Rsp) message according to the unregistered sign of storage and the corresponding relation of IP-SM-GW to SMS-GMSC, return the address of IP-SM-GW;

The address of carrying IP-SM-GW in the described route response message.

Step a5, SMS-GMSC are forwarded to corresponding IP-SM-GW according to the address of the IP-SM-GW that receives with note.

Method 12: on HSS/HLR, set in advance the corresponding relation of unregistered sign and a plurality of IP-SM-GW address, and dynamically specify an IP-SM-GW by HSS/HLR; When SMS-GMSC when HSS/HLR sends route requests to application server AS address, described unregistered sign place, by HSS/HLR SMS-GMSC is returned in this IP-SM-GW address of appointment;

Specific implementation process can be:

Step b1, on HSS/HLR the corresponding relation of pre-configured unregistered sign and a plurality of IP-SM-GW, and be the E.164 address that described unregistered sign is dynamically specified an IP-SM-GW by HSS/HLR;

Step b2 to step b5 with step a2 to step a5.

Method 13: at the network node of Short Message Service Gateway to the route signaling process between HSS/HLR, as the corresponding relation of unregistered sign and certain IP-SM-GW address is set on certain route signaling catching point, and get the route requests signaling to HSS/HLR by this network node interception SMS-GMSC; And return the corresponding IP-SM-GW address of unregistered sign to SMS-GMSC by this network node.

Specific implementation process can be:

Step c1, in SMS-GMSC corresponding IP-SM-GW address of pre-configured unregistered sign to the network node of the route signaling process between HSS/HLR;

Described network node can be certain route signaling catching point between SMS-GMSC and HSS/HLR, or this network node can be set specially.

Step c2, SMSC send note to SMS-GMSC;

Step c3, SMS-GMSC send to the route requests that HSS/HLR gets unregistered sign;

The above-mentioned signaling of getting route of described signaling catching point interception between step c4, SMS-GMSC and HSS/HLR;

Step c5, the described signaling catching corresponding IP-SM-GW address of unregistered sign of naming a person for a particular job sends to described SMS-GMSC.

Return the IP-SM-GW address by described signaling catching point and can accomplish to need not on HSS/HLR, to search this IP-SM-GW address information.

In addition, when the callee is the UE of described signatory unregistered service, if this UE is designated the UE that nullifies in registration back, IMS territory, then obtain the IP-SM-GW address corresponding with this UE by the Short Message Service Gateway node to corresponding home domain deposit unit, HSS/HLR identifies the IP-SM-GW address of being registered when registering last time with this UE and returns described Short Message Service Gateway node.

The present invention has provided the corresponding implementation method at step 2 simultaneously, and at first, when the callee was described public service identity, described step 2 can realize by the following method, be respectively:

Method 21, IP-SM-GW are routed directly to AS:IP-SM-GW and strengthen partial function, promptly strengthen query function, to unit, the AS of public service identity correspondence address information place, AS address as HSS/HLR inquiry public service identity correspondence, and after fetching this AS address, described note is routed to this AS;

Method 22, IP-SM-GW specify an I-CSCF by the AS:IP-SM-GW that routes indirectly to of I-CSCF, give this I-CSCF the note route earlier, afterwards by the AS address information place unit of this I-CSCF to the public service identity correspondence, fetch the pairing AS of public service identity address as HSS/HLR, then described note is routed to this AS;

Method 23, IP-SM-GW are to dns server inquiry AS address: IP-SM-GW safeguards the tabulation of institute's support region or network title, if the corresponding domain names coupling of public service identity that the note that related content and IP-SM-GW receive in this tabulation that IP-SM-GW safeguarded is called, IP-SM-GW is routed to this AS with described note then to the AS address of DNS inquiry and acquisition public service identity correspondence so.

When the callee is the described unregistered sign in IMS territory, during as the UE of public service identity or signatory unregistered service, step 2 can realize by the following method, comprise:

Method 24, IP-SM-GW route indirectly to AS:IP-SM-GW by S-CSCF and obtain a S-CSCF who handles unregistered identification service earlier, afterwards note are routed to this S-CSCF, are routed to the AS at unregistered sign place again by this S-CSCF.

What need supplementary notes is, when addressing system adopts described method 21 or method 22, correspondingly, in described step a1, the step b1 or step c1 of described method 11, method 12 or method 13 correspondences, remove described IP-SM-GW address need be set, the AS address at described public service identity place also need be set on the network node of appointment, described AS address can be set in home domain location register unit, a network node perhaps is set in network specially, the AS address is set on this network node.In the elaboration of following specific embodiment to method 21, method 22, method 23 and method 24, be example so that described AS address to be set on HSS/HLR.

In addition, said method 21 is to method 24, and IP-SM-GW is unlike to common registered user validity check being carried out in the associated S-CSCF address of unregistered sign.Because for the registered user, IP-SM-GW can carry out validity check to the address that this user is registered to S-CSCF, and after check effectively, continues the transmission flow of note; And described unregistered sign not registered process, therefore IP-SM-GW can't detect the validity into certain S-CSCF address of unregistered sign appointment, if still require IP-SM-GW that validity check is done in the S-CSCF address of unregistered sign, ensuing routing procedure can't be carried out, whole termination note process was lost efficacy.
