Description
Technical field
The present invention relates to communication technical field, processing method, system and the equipment of the dissimilar messaging service communication of particularly dialogue-based initiation protocol (SIP, SessionInitiation Protocol).
Background technology
IP Multimedia System (IMS, IP Multimedia Subsystem) is the subsystem of 3GPP at the support IP multimedia service of stage 5 (Release5) version proposition, its core characteristics be adopt Session Initiation Protocol and with the independence that inserts, therefore IMS is a multimedia control/calling controlling platform on the IP territory, support conversation class and non-conversation class multimedia service, for the multimedia application in future provides a general business to enable platform, it is to provide the essential step of system evolution to complete IP network (All IP Network) business.Along with rise and development based on the access technology of IMS, how the messaging service with existing traditional mobile terminal is converted into the business that the IMS terminal can provide, on the basis of reusing existing mobile network short message business function entity and agreement as far as possible, realization is based on the SIP based information series business of IMS framework, instant message (Immediate Messaging) and conversation-based message (Session based messaging) as definition among the 3GPP (third generation partner planning standard tissue), and the Session initiation Protocol (SIMPLE at instant messages and expression expansion of OMA definition, SessionInitiation Protocol for Instant Messaging and Presence Leveraging Extensions), with traditional messaging service, as the Short Message Service (SMS) of 3GPP definition and the business intercommunication between the Enhanced Message Service (EMS), also be a target of each operator's question of common concern and 3GPP standardization body.
Because the EMS of 3GPP definition belongs to the SMS that strengthens type, for for simplicity, the short message in traditional C as herein described/PS territory has comprised the messaging service of SMS and two forms of EMS simultaneously.
Fig. 1 is the network frame that the use IP terminal of present 3GPP proposition realizes traditional short message service, and wherein Short Message Entity (SME), Short Message Service Center (SM-SC), short message mobile switching centre gateway/short message intercommunication mobile switching centre (SMS-GMSC/SMS-IWMSC), home signature user server/attaching position register (HSS/HLR) are that existing mobile network is realized the functional entity that short message (SMS) is professional.SM-SC is used for storing short message; When SMS-GMSC is used for terminal reception short message, to HSS/HLR inquiry routing iinformation; SMS-IWMSC carries out authentication etc. when being used for terminal and sending SMS message.The short message service center that uses in the present network, all be that collection SM-SC, SMS-GMSC and three of SMS-IWMSC are the equipment of one, these three functional entitys are not realized as independent physical equipment, so hereinafter, short message service center or traditional short message service center promptly represent the equipment of SM-SC, SMS-GMSC and three one of SMS-IWMSC if no special instructions.HSS/HLR is used to store user's data information, comprises user's signing service data and routing iinformation.Network frame shown in Figure 1 also comprises charging network management function/charging data function (CGF/CDF) and Online Charging System (OCS), CGF/CDF is used to collect the also ticket information of the offline charging of process user, be passed to the charging center then, OCS is used to collect the also ticket information of process user online charging, is passed to the charging center then.
Among Fig. 1, IP message gateway (IP-Message-GW, hereinafter with among the figure also be designated as IP-SM-GW) gathered the function of the entity SMI AS (Short Message/IMS messaging interworkingApplication Server) of message intercommunication, be used to realize the communication between IP client and the GMSC/SMS-IWMSC, need carry out IP network messaging protocol (promptly based on the IP-based communication protocol of using between IP terminal and the IP-Message-GW) and existing WCDMA/GSM network short-message protocol (is the MAP that uses between IP-Message-GW and the GMSC/SMS-IWMSC, be similar in the implementation procedure of present short message the MAP between MSC and SGSN and the GMSC/SMS-IWMSC) between the intercommunication that comprises transport layer and service layer.Wherein, the intercommunication of transportation level is the intercommunication of the professional and traditional MAP short message service of the SIP Message of encapsulation MAP agreement (MAP) short message realized of original IP-SM-GW; The intercommunication of service aspect is the intercommunication based on the professional and traditional MAP short message service of the instant message (SIMPLEIM) based on the Session initiation Protocol of the expression expansion of OMA of Session Initiation Protocol that SMI AS realizes.When the user who supports IP to insert uses short message service, must be registered to earlier on the IP-SM-GW, registered and the IP-SM-GW address of IP-SM-GW notice this user of HSS, it is IP Connected that HSS preserves User Status, and stores the IP-SM-GW address of corresponding user's registration.
In existing standard, IMS messaging services and traditional short message service have been proposed based on the transportation level and the message intercommunication on the service aspect, wherein, IP message gateway (IP-SM-GW) has been gathered the function of SMIAS, as the short message bearing interconnection gateway between IMS territory and traditional circuit domain and the packet domain (CS/PS territory), realized based on the intercommunication on the transportation level of the message of SIP and traditional short message, as the sip message of encapsulating MAP short message is carried out decapsulation, and the MAP short message is encapsulated in processing in the sip message body, realized simultaneously based on the intercommunication on the message of SIP and the traditional Short Message Service aspect, as conversion that message and MAP short message based on SIP are carried out message format etc., and the message after will handling is transmitted accordingly, simultaneously, the IP message gateway is for the message that receives, and can also be provided with in the preference according to the strategy of operator and user to select corresponding territory to carry out route to message.
Wherein, for based on the message of SIP and the traditional intercommunication of short message on transportation level, IP client is registered to shown in handling process Fig. 2 of IP-Message-GW.
Figure 2 shows that existing based on sip message and traditional short message register flow path schematic diagram in the transport layer intercommunication.
Step 3, in registration process, S-CSCF checks the initial filter criteria of downloading from HSS, this initial filter criteria is to stipulate in the existing protocol, no longer describes in detail herein.This initial filter criteria is called first initial filter criteria herein.
Step 5, the IP message gateway returns success response to S-CSCF.
The information that step 7, HSS storage receive, and return the registration response of IP-IWF (IPinterworking function) to the IP message gateway, comprising providing service relevant subscription data.
So far, UE is registered on the IP message gateway, and the IP message gateway has obtained the subscription data relevant with service from HSS.
According to above-mentioned register flow path, traditional short message service and in the flow process of IMS-MO (message in IMS territory is initial) as shown in Figure 3 based on the intercommunication on the messaging service service aspect of SIP.
Step 3, S-CSCF carries out the inspection of second initial filter criteria to what receive based on the message of SIP, this inspection comprises whether the ability characteristics sign (feature tag) that this sip message carries is pure IMS message "+g.oma.sip-im ", or the IMS message of encapsulation "+g.3gpp.smsip ", or check calling subscriber's interworking service of service aspect of whether having contracted, or whether the message identification of checking the CSID that sip message carries is the intercommunication class business of service aspect etc.
Step 5, the IP message gateway of caller network judges whether that according to calling subscriber's preference and carrier policy needs serve the intercommunication of aspect, and have three kinds of possible situations this moment: need the service aspect intercommunication, handle, do not need the intercommunication of service aspect by default situations.
The intercommunication of capable service aspect if desired, then the IP message gateway is authorized interworking service, if authorize successfully, the IP message gateway of caller network becomes traditional short message format to the message conversion based on SIP, the message of format transformation is forwarded to traditional short-message system, finishes follow-up repeating process by traditional short-message system.
Handle by default situations if desired, then the IP message gateway of caller network is selected the called territory network that sip message issues according to called subscriber's sign.If the called subscriber is the form of TEL-URI, the IP message gateway of caller network can be to carry out issuing of message by the IMS territory or by the CS/PS territory according to the number segment information of self-configuring or result's selection of ENUM (Telephone Number Mapping working group) inquiry.
If the territory of selecting message to issue is the CS/PS territory, the IP message gateway of caller network is authorized interworking service, if authorize successfully, the IP message gateway of caller network becomes traditional short message format to the message conversion based on SIP, the forwards of format transformation to traditional short-message system, finish follow-up repeating process by traditional short-message system, if authorize not success, the IP message gateway of caller network returns the S-CSCF of failure reporting to the caller network; If the territory of selecting message to issue is the IMS territory, forward the message to the called IMS network by prior art.
If do not need to serve the aspect intercommunication, what then the IP message gateway was selected according to the result of the number segment information of self-configuring or ENUM inquiry is the IMS territory, forward the message to the called IMS network by prior art, if the IP message gateway can not be selected the IMS territory, then return the S-CSCF of failure reporting to the caller network.That is to say that if do not need to serve the aspect intercommunication, then the IP message gateway can not be selected the CS/PS territory, can only select IMS territory issuing message, when selecting to get nowhere, return failure reporting in the IMS territory.
From existing standard, the intercommunication of IMS messaging services is confined to message (as the SIP MESSAGE and the OMA SIMPLE IM of encapsulating MAP short message) based on SIP and the intercommunication between the traditional MAP short message, comprise the intercommunication on transportation level and the service aspect, based on the intercommunication between the sip message (as the SIP MESSAGE and the OMA SIMPLE IM of encapsulating MAP short message), existing standard does not relate to for dissimilar.And the SIP MESSAGE of encapsulating MAP short message still a kind of MAP short message service in essence, only under supporting the situation of MAP stack, the called subscriber could resolve such message, called subscriber for the pure IMS that does not support the MAP stack, when receiving the SIP MESSAGE of encapsulating MAP short message, just can't resolve message.In addition, do not support the MAP stack for caller IMS user, and the called IMS user supports MAP stack and user preference to receive by the IMS territory under the situation of MAP short message, also needs the sip message (as OMA SIMPLE IM) to non-encapsulation format to carry out the conversion of form.

Below in conjunction with drawings and the specific embodiments, the present invention is elaborated again.
Embodiment one:
The processing method that the dissimilar messaging service based on SIP that the present embodiment provides is communicated by letter, comprise: callee side S-CSCF receives the sip message based on the first kind from call subscriber terminal UE, sends described sip message based on the first kind in the called network side interworking function entity; Interworking function entity in the called network side is converted to sip message based on second type with described sip message based on the first kind, and described sip message based on second type is sent to called UE.
The intercommunication that the above-mentioned interworking function entity that is positioned at the called network side can judge whether the aspect of need serving according to the called subscriber's who obtains information (as terminal called ability/called subscriber's preference etc.) or carrier policy, carry out the authentication of interworking service, the function of the conversion of message format, it can be the entity that is arranged in existing network, as be positioned at IP message gateway, SMI AS etc., also can be the independent net-work entities that increases newly, or the functional module that increases newly on the existing network entity.It provides service by user's third-party registration for the user.
After the sip message based on the first kind of above-mentioned callee side S-CSCF reception from calling UE, described sip message based on the first kind is sent to before the interworking function entity in the called network side, can further include: determine whether that according to initial filter criteria needs send described sip message based on the first kind in the called network side interworking function entity, if carry out transfer operation again; Otherwise, directly described sip message based on the first kind is sent to called UE by prior art.
Interworking function entity in the above-mentioned called network side will be converted to based on the sip message of the first kind before the sip message based on second type, can further include: determine whether the intercommunication of the aspect of need serving, if, again described called UE is carried out the interworking service mandate, after the service authorization success, described sip message based on the first kind is converted to sip message based on second type.
After will being sent to called UE based on the sip message of second type, can further include: called UE returns response message for described calling UE.
Shown in Figure 4 is one the schematic flow sheet based on the dissimilar messaging service communication processing method of SIP according to an embodiment of the present invention.For for simplicity, the network entity relevant with the present embodiment only is provided among the figure, other network entity, as IMS core network entity S-CSCF, related flow process such as P-CSCF is all consistent with prior art, no longer does repeated description.
Step 3, interworking function entity promptly is forwarded to the called IMS user to the sip message after the format conversion based on the sip message of second type by IMS core.
Referring to Fig. 5, it is based on a specific embodiment of embodiment one.In the present embodiment, calling and called UE place network side is provided with interworking function entity, and this interworking function entity is realized by the IP message gateway.Calling UE is an IMS registered user who supports the MAP stack, and the sip message that sends an encapsulating MAP short message is to the called UE of not supporting the MAP stack (as SIMPLE IM user).Here, entity in the caller network is designated as " physical name # 1 ", entity in the called network is designated as " physical name # 2 ", for example, calling UE is designated as UE# 1, and called UE is designated as UE# 2, and the S-CSCF in the caller network is designated as S-CSCF# 1, S-CSCF in the called network is designated as S-CSCF# 2, or the like.
Step 8～9, S-CSCF# 2 carries out the inspection of initial filter criteria to the sip message that receives, and whether carries the feature tag of "+g.3gpp.smsip " etc. comprising sip message.Check result based on initial filter criteria, if sip message has carried the feature tag of "+g.3gpp.smsip ", identify in this sip message body and carried the MAP short message, it is IP-SM-GW# 2 that S-CSCF# 2 is routed to called IP message gateway to the sip message of encapsulation.
Step 10, after IP-SM-GW# 2 received the sip message of encapsulating MAP short message, according to the strategy of called user information of obtaining or operator, whether decision needed the intercommunication of the aspect of serving.This called user information comprises the ability of terminal called, called subscriber's service contracting or called subscriber's preference.
Serve the intercommunication of aspect if desired, IP-SM-GW# 2 carries out the mandate of interworking service to UE# 2, carry out the conversion of message format after authorizing successfully, promptly the sip message that encapsulates is carried out decapsulation and obtain the MAP short message later on, again the MAP short message conversion is become the form of pure sip message, under the authorization failure situation, then return errored response to UE# 1; If do not need the intercommunication of the aspect of serving, message be issued to called user terminal by IMScore.
Step 11～12, IP-SM-GW# 2 finishes after the processing of interworking service, by IMS core, the pure sip message after the conversion is issued to UE# 2.
The response 200OK that step 13-19, UE# 2 successfully receive by the IP-SM-GW# 2 return messages is to UE# 1.
The situation of another possibility is not dispose any interworking function entity (as IP-SM-GW and SMI AS) at the caller network, at this moment, according to the IMS message process mode of prior art (TS 23.228), S-CSCF# 1 can directly be routed to S-CSCF# 2 to the sip message of encapsulating MAP short message by IMS core.Receive the sip message of encapsulating MAP message as S-CSCF# 2 after, the step 8 among its subsequent processes and Fig. 5～19 are identical, repeat no more.
So far, communicating by letter between the calling UE that has realized supporting the MAP stack and the called UE of not supporting the MAP stack (as SIMPLE IM user).
Referring to Fig. 6, it is based on another specific embodiment of embodiment one.In the present embodiment, calling and called UE place network side is provided with interworking function entity, and this interworking function entity is realized by the IP message gateway.Calling UE sends a SIMPLE IM to the called IMS network, and called UE is not IM user, and preference is by the form reception sip message of MAP signaling.Here, the entity in the caller network is designated as " physical name # 1 ", the entity in the called network is designated as " physical name # 2 ", for example, calling UE is designated as UE# 1, and called UE is designated as UE# 2.
Step 8～9, S-CSCF# 2 carries out the inspection of initial filter criteria to the sip message that receives, and whether carries the feature tag of "+g.oma.sip-im " comprising sip message, or does not carry interworking service identifier CSID of service aspect etc.Check result based on initial filter criteria, if sip message has carried the feature tag of "+g.oma.sip-im ", or carried expression and need serve the interworking service identifier CSID of aspect, it is IP-SM-GW# 2 that S-CSCF# 2 is routed to called IP message gateway to the SIMPLE IM message that receives.
Step 10, after IP-SM-GW# 2 received SIMPLE IM message, according to the strategy of called user information of obtaining or operator, whether decision needed the intercommunication of the aspect of serving.This called user information comprises the ability of terminal called, called subscriber's service contracting or called subscriber's preference.
Serve the intercommunication of aspect if desired, IP-SM-GW# 2 carries out the mandate of interworking service to UE# 2, carry out the conversion of message format after authorizing successfully, being about to SIMPLE IM message conversion is the MAP short message and is encapsulated in the sip message, under the authorization failure situation, then return errored response to UE# 1; If do not need the intercommunication of the aspect of serving, message is issued to called user terminal by IMS core.
Step 11～12, IP-SM-GW# 2 finishes after the processing of interworking service, by IMS core, the sip message of encapsulating MAP short message is issued to UE# 2.
The response 200OK that step 13-19, UE# 2 successfully receive by the IP-SM-GW# 2 return messages is to UE# 1.
The situation of another possibility is not dispose any interworking function entity (as IP-SM-GW and SMI AS) at the caller network, at this moment, according to the IMS message process mode of prior art (TS 23.228), S-CSCF# 1 can directly be routed to S-CSCF# 2 to SIMPLE IM message by IMS core.After S-CSCF# 2 received SIMPLE IM message, the step 8 among its subsequent processes and Fig. 6～19 were identical, repeat no more.
So far, communicating by letter between the calling UE (as SIMPLE IM user) that has realized not supporting the MAP stack and the called UE of supporting the MAP stack.
From the foregoing description as can be seen, for calling UE is an IMS registered user who supports the MAP stack, send the situation of the sip message of an encapsulating MAP short message to the IMS user who does not support the MAP stack (as SIMPLE IM user), perhaps, calling UE sends a SIMPLE IM to the called IMS network, and called UE is not IM user, and preference is by the situation of the form reception sip message of MAP signaling, if caller network side in calling UE place is provided with interworking function entity; Then the interworking function entity in the caller network side receives the sip message based on the first kind from Calling Side S-CSCF, judge the signatory interworking service of calling subscriber or when not needing to serve the aspect intercommunication, send described sip message to described Calling Side S-CSCF based on the first kind; This moment, Calling Side S-CSCF sent described sip message based on the first kind to described callee side S-CSCF.If caller network side in calling UE place is not provided with interworking function entity; After then Calling Side S-CSCF receives the sip message based on the first kind from described calling UE, can directly send described sip message to described callee side S-CSCF according to existing protocol based on the first kind.Described sip message based on the first kind is the sip message of encapsulating MAP; Described sip message based on second type is pure sip message; Perhaps, described sip message based on the first kind is pure sip message, and described sip message based on second type is the sip message of encapsulating MAP; Described pure sip message comprises SIMPLE IM message.

Use the present embodiment, do not support at called network under the situation of message intercommunication entity or functional module, need not that existing IMS core is done any change and can realize that also the sip message of encapsulating MAP short message communicates by letter with pure sip message (as OMA SIMPLE IM).Specifically can be: IMS core network entity (as S-CSCF) judges according to the ability (as supporting MAP stack etc.) that the calling subscriber who carries in the sip message body requires terminal called to have whether terminal called possesses this ability, if do not possess, this network entity returns errored response to the calling subscriber, and carry the ability information of terminal called, make the calling subscriber to send and the adaptive message of terminal called ability according to this information based on SIP.
Referring to Fig. 7, it is based on a specific embodiment of embodiment two.In the present embodiment, calling UE is an IMS registered user who supports the MAP stack, and the sip message that sends an encapsulating MAP short message is to the called UE of not supporting the MAP stack (as SIMPLE IM user).Here, the entity in the caller network is designated as " physical name # 1 ", the entity in the called network is designated as " physical name # 2 ", for example, calling UE is designated as UE# 1, and called UE is designated as UE# 2.
Step 1-7, similar with step 2～7 among Fig. 3, different is: UE# 1 is encapsulated in the MAP short message in the sip message body, and in the sip message head, as " require ", carry the identifier that needs UE# 2 to support the MAP stack, by IMS core sip message being forwarded to caller IP message gateway is IP-SM-GW#1.IP-SM-GW# 1 is behind the sip message that receives from UE# 1, confirm that this message is the sip message of encapsulating MAP short message, but the not signatory any interworking service of calling subscriber, comprise the intercommunication of transportation level and/or service aspect, and can carry out route at the called IMS network according to the terminal called sign that message is carried, so IP-SM-GW# 1 returns the sip message of encapsulation to S-CSCF# 1, by IMS core this sip message is routed to S-CSCF# 2 by S-CSCF# 1.
Step 8, after S-CSCF# 2 receives the sip message of encapsulation, detect and carried caller in the message header of this message and require terminal called to support the identifier of MAP, and know that according to the terminal called ability information of obtaining when the third-party registration terminal called do not support the MAP stack, therefore, the sip message of this encapsulation of decision refusal, and structure errored response, the ability information of carrying failure cause and terminal called in this errored response.
Step 10～12, S-CSCF# 2 returns errored response to UE# 1.
13) after UE# 1 received errored response, according to the terminal called ability information of carrying in the response, constructing not, the sip message of encapsulating MAP short message sent to terminal called.
The situation of another possibility is not dispose any interworking function entity (as IP-SM-GW and SMI AS) at the caller network, at this moment, according to the IMS message process mode of prior art (TS23.228), S-CSCF# 1 can directly be routed to S-CSCF# 2 to the sip message of encapsulating MAP short message by IMS core.Receive the sip message of encapsulating MAP message as S-CSCF# 2 after, the step 8 among its subsequent processes and Fig. 7～13 are identical, repeat no more.
