Fig. 3 is the composition structural representation of the service environment framework realizing the inventive method flow process, and Fig. 3 comprises: CPM client, participant's functional module (PF), effector's functional module (CF), Interactive Selection module (ISF), IWF, cluster server, MMS system, multimedia message client.Under this simple declaration: wherein, CPM client is used for receiving/send out group message, and message disposition notification, to PF, represents message content to user and accepts a message receipts/operation of user; PF is used for as user agent, forwards and opens and exhale request message to arrive object user, receives final call message and is forwarded to the CPM client of object user; The function class that CF and PF realizes seemingly, is all as group service agency, for the treatment of group message related procedure; ISF is for selecting suitable conventional message interactive mode; IWF is used for CPM message conversion to become conventional message formats, be sent to conventional message operation system, conventional message formats is converted to CPM message, such as: the message conversion of CPM type is become MMS format and is sent to MMS system, MMS format is converted again to the information and sending of CPM type to CPM client; The configuration information that cluster server is correlated with for depositing group, for other unit provide group configuration information; MMS system is a type of multi-media service system, for receiving multimedia message and sending to IWF, and sends to multimedia message client; Multimedia message client is used for sending and receiving multimedia message message to MMS system, and here, multimedia message client is the specific implementation of Multimedia Message client in Fig. 2.
Here, when taking the composition structural representation of the service environment framework shown in Fig. 3, the present invention mainly comprises following content:
One, CPM client sends group message and processes request to group member, and clearly needs to return the group message process receipt for this group message process request, and here, group message process receipt can be understood as the processing notice information of group message.After group message process request is sent to CF, for predefine group, CF obtains group member address from cluster server; And for interim group, from message body, obtain group member address, wherein certain member addresses is circuit domain (CS)/data field (PS) address MDN.CF needs the interactive mode judging that this group message process request of transmission adopts, then this group message process request is sent to ISF by CF, by ISF based on destination address type, message content and group address information etc., determine the interactive mode needing to adopt, when the client such as receiving this group message process request is multimedia message client, multimedia message mode is adopted to send this group message process request.After ISF determines the interactive mode needing to adopt, this group message process request is sent to IWF by ISF.
Two, IWF newly produces a message identifier, and preserves this message identifier, for predefine group, needs to preserve IMDN-Record-Route field value and Referred-by field value; And for provisional group, need to preserve IMDN-Record-Route field value and original-to field value, and the message conversion of CPM type is become the message of MMS format, adopt MM4 interface that the message of MMS format is sent to MMS system.
Three, IWF receives the group message process receipt returned from MMS system, take out the message identifier in this group message process receipt, compare with the message identifier of having preserved before, determine corresponding preservation information, and converting the message of IMDN form to, the message of IMDN form is the message of CPM type here.For predefine group, using the value of the IMDN-Record-Route field value of preservation as imdn-route field, and the Referred-by field of preservation and field value thereof are added in the message of the IMDN form after conversion; And for provisional group, using the value of the IMDN-Record-Route field value of preservation as imdn-route field, and using the value of the original-to field value of preservation as original-recipient-uri field in IMDN message body.The message of the IMDN form processed sends to CPM client by IWF.
Four, the imdn-route information comprised in the message according to IMDN form, IMDN message is sent to CF and PF by SIP/IP Core, is finally sent to CPM client.
In sum, adopt the present invention, compared with prior art, the present invention is by preserving the critical field in group message process request at IWF, the group message process receipt achieved from multimedia information service system is successfully sent to the CPM client sending this group message process request, thus ensure that the business experience of CPM user, the acceptance level of CPM business in user after improving.
Here, in following methods embodiment, support from multimedia information service system return group message process receipt to CPM operation system service environment framework as shown in Figure 3, CPM client sends group message and processes request to CPM operation system, first PF is arrived, after PF carries out Authentication Authorization to CPM client, by group message process request forward to CF; When CF judges to need group message process request to be sent to certain non-CPM user, group message process request is sent to ISF, after ISF determines interactive mode, by group message process request forward to the IWF with MMS system interaction, after IWF converts the message format of CPM type the message of MMS format to, adopt MM4 interface to send it to MMS system, by MMS system, the group message process request of MMS format is sent to multimedia message client; MMS system is forwarded to IWF after multimedia message client receives the group message process receipt of MMS format, after IWF converts the group message process receipt of MMS format the message of IMDN form to, according to routing iinformation, the group message process receipt of IMDN form is forwarded to CF and PF, finally reaches CPM client.Be predefine group or interim group for group below, set forth the method flow realizing group message process notice and transmit respectively.
Embodiment of the method one: group is the situation of predefine group.
Step 201, CPM client send group message and process request to group member, and adopt sip message during transmission, this group message process request is the message of page-mode.
Here, in group message process request, the field value of request-uri field is set to group address mark; When SIP/IP Core is 3GPP IMS network, the field value of p-preferred-identity field is set to the public user identity (PUI, public user identity) of CPM client; Accept-contact field is carried CPM service identification information, and namely the field value of accept-contact field is CPM service identification information, such as: OMA-CPM-Tag; The field value of IMDN.disposition-notification field is set to positive-delivery, represents and need recipient to send return receipt report; Message is forwarded to the PF of CPM client ownership by the p-asserted-identity field value of SIP/IP CORE foundation CPM client and accept-contact field value.
The group address mark that step 202, PF forwarding group Message handling request carry to SIP/IP Core, SIP/IP Core according to request-uri field, group of routes Message handling request is to CF.
Step 203, CF obtain group member address according to group address mark from cluster server, wherein have the address of a member to be address in CS/PS territory; Produce a new message, namely re-construct group message process request, to be sent to ISF by CF.
Here, CF judges according to group member address, needs to adopt interactive mode to send this message, then, in the group message process request re-constructed, the field value of request-uri field is set to the SIP URI address of ISF; The field value of p-asserted-identity field is set to group address mark; The field value of refered-by field is set to the PUI of CPM client; Accept-contact field carries CPM service identification information; The group member address obtained is carried in the message body of sip message, and message is transmitted to ISF by the ISF address designation that SIP/IP Core carries according to request-uri field.
Step 204, ISF receive group message process request from CF, judge the group member address style of carrying in group message process request, it is the MDN address in CS/PS territory in this example, then obtain CS/PS address corresponding to group address from cluster server, and using the field value of this address as second p-asserted-identity field; ISF judges according to the length of group address type and group member address style and message body content, need to adopt multimedia message mode to send group message and process request to object group member, then re-construct group message process request, to be sent to IWF by ISF, and select the field value of SIP URI address as request-uri field of a suitable IWF, send a message to SIP/IP Core, message is transmitted to IWF according to the field value of request-uri field by SIP/IPCore.
Step 205, IWF receive group message process request from ISF, preserve referred-by field, and take out the destination address that carries in message body as destination address, and second p-asserted-identity field is as source address; Message content is converted to the group message process request of MMS format, and adopt MM4 interface to be sent to MMS system.
Here, the mark needing return receipt report is carried in MM4 interface message, IWF can produce the identification information of MM4 interface message, for corresponding with response message, correspondingly with message identifier also preserve the information such as the via field of request message, for returning response message to CPM client, if there is IMDN-Record-Route field, then preserve respective field.
Step 206, MMS system adopt MM4 interface successfully to return first response message.
Step 207, IWF convert successful first response message of MM4 mouth feedback to sip response message, are forwarded to ISF according to the via information of preserving.
Here it is pointed out that because IWF needs waiting receipt report message, namely for the group message process receipt of group message process request, therefore, do not discharge the field information preserved at this IWF.
First response message is sent to CF according to via information by step 208, ISF.
Step 209, CF return sip response message to PF after receiving first response message, carry the via field value of request message corresponding to this response message in message.
Step 210, PF forward first response message to CPM client.
The group message process request of MMS format is sent to multimedia message client by step 211, MMS system.
Step 212, multimedia message client return second response message, and namely group message process receipt is to MMS system.
Step 213, multimedia message client send group message process receipt to MMS system.
Group message process receipt is sent to IWF by step 214, MMS system.
Step 215, IWF convert group message process receipt to IMDN form according to RFC5438 specification, and the information of message identifier and the message identifier correspondence preservation kept in IWF is found according to the message identifier in group message process receipt, and the group message process receipt of IMDN form is formed according to the content in group message process receipt, adopt sip message during transmission.
Here, in group message process receipt, the field value of request-uri field being set to group address mark, is TEL URI form; The field value of p-asserted-identity field being set to the group member address designation of MMS customer, is TEL URI form; Referred-by field preserves CPM client address information, is SIP URI form; Imdn-route field directly uses the IMDN-Record-Route field value preserved, and what preserve in this example is the address of CF and PF; SIP/IP Core converts the group address of TEL URI form mark to SIP URI form, and group message process receipt is routed to CF according to the SIP URI address after conversion or routing iinformation by SIP/IP Core.
After step 216, CF receive group message process receipt from IWF, a new generation message, namely re-constructs group message process receipt, to be sent to PF by CF.
Here, in the group message process receipt re-constructed, the field value of request-uri field is set to the field value of the referred-by field receiving message; The field value of p-asserted-identity field is set to the field value of the p-asserted-identity field receiving message.CF can integrate the multiple group message process receipts received, and also can not integrate.Group message process receipt is forwarded to PF according to the field value of request-uri field by SIP/IP Core.
Group message process receipt is sent to CPM client by SIP/IP Core by step 217, PF; The response message returned, via the forwarding of PF, CF, IWF and MMS system, is forwarded to multimedia message client by CPM client.
Embodiment of the method two: group is the situation of provisional group.
Step 301, CPM client send group message and process request to group member, and adopt sip message during transmission, this group message process request is the message of page-mode.
Here, in group message process request, the field value of request-uri field is set to group address mark; When SIP/IP Core is 3GPP IMS network, the field value of p-preferred-identity field is set to the PUI of CPM client; Accept-contact field is carried CPM service identification information, and namely the field value of accept-contact field is CPM service identification information, such as: OMA-CPM-Tag; The field value of IMDN.disposition-notification field is set to positive-delivery, represents and need recipient to send return receipt report; Message is forwarded to the PF of CPM client ownership by the p-asserted-identity field value of SIP/IP CORE foundation CPM client and accept-contact field value.
The group address mark that step 302, PF forwarding group Message handling request carry to SIP/IP Core, SIP/IP Core according to request-uri field, group of routes Message handling request is to CF.
According to group address information, step 303, CF judge that this group is interim group, group member address in message body, then obtains group member address from message body, wherein have the address of a member to be address in CS/PS territory; Produce a new message, namely re-construct group message process request, to be sent to ISF by CF.
Here, CF judges according to group member address, needs to adopt interactive mode to send this message, then, in the group message process request re-constructed, the field value of request-uri field is set to the SIP URI address of ISF; The field value of p-asserted-identity field is set to CPM client address mark; The field value of original-to field is set to interim group address; Accept-contact field carries CPM service identification information; The group member address obtained is carried in the message body of sip message, and message is transmitted to ISF by the ISF address designation that SIP/IP Core carries according to request-uri field.
Step 304, ISF receive group message process request from CF, judge the group member address style of carrying in group message process request, it is the MDN address in CS/PS territory in this example, then from the user that CPM client is corresponding configures, obtain corresponding CS/PS address, and using the field value of this address as second p-asserted-identity field; ISF judges according to the length of group address type and group member address style and message body content, need to adopt multimedia message mode to send group message and process request to object group member, then re-construct group message process request, to be sent to IWF by ISF, and select the field value of SIP URI address as request-uri field of a suitable IWF, send a message to SIP/IPCore, message is transmitted to IWF according to the field value of request-uri field by SIP/IP Core.
Step 305, IWF receive group message process request from ISF, preserve original-to field, and take out the destination address that carries in message body as destination address, and second p-asserted-identity field is as source address; Message content is converted to the group message process request of MMS format, and adopt MM4 interface to be sent to MMS system.
Here, the mark needing return receipt report is carried in MM4 interface message, IWF can produce the identification information of MM4 interface message, for corresponding with response message, correspondingly with message identifier also preserve the information such as the via field of request message, for returning response message to CPM client, if there is IMDN-Record-Route field, then preserve respective field.
Step 306, MMS system adopt MM4 interface successfully to return first response message.
MM4 mouth feedback success response message conversion is become sip response message by step 307, IWF, is forwarded to ISF according to the via information of preserving.
Here it is pointed out that because IWF needs waiting receipt report message, namely for the group message process receipt of group message process request, therefore, do not discharge the field information preserved at this IWF.
First response message is sent to CF according to via information by step 308, ISF.
Step 309, CF return sip response message to PF after receiving first response message, carry the via field value of request message corresponding to this response message in message.
Step 310, PF forward first response message to CPM client.
The group message process request of MMS format is sent to multimedia message client by step 311, MMS system.
Step 312, multimedia message client return second response message, and namely group message process receipt is to MMS system.
Step 313, multimedia message client send group message process receipt to MMS system.
Group message process receipt is sent to IWF by step 314, MMS system.
Step 315, IWF convert group message process receipt to IMDN form according to RFC5438 specification, and the information of message identifier and the message identifier correspondence preservation kept in IWF is found according to the message identifier in group message process receipt, and the group message process receipt of IMDN form is formed according to the content in group message process receipt, adopt sip message during transmission.
