The following describes the embodiments in further detail with reference to the accompanying drawings.

As shown in fig. 1, a method for implementing service interaction between different messages includes the following steps:

step 101, the PF receives the CPM message, sets a request-uri field of the CPM message as a related address of the ISF, and forwards the CPM message to the ISF.

And 102, the ISF sets a request-uri field of the CPM message as a related address of the IWF and then forwards the CPM message to the IWF, and the IWF converts the CPM message into a traditional message.

For the above technical solution comprising steps 101 to 102, the specific processing procedure of step 101 includes:

step 101a, the PF receives a CPM message from the CPM client. The destination user address of the CPM message is a traditional message user address, and the source user address is a CPM user address.

And step 101b, the PF judges that the CPM message needs to be sent to the traditional message user in an interactive mode according to the traditional message user address, and sets a request-URI field as the SIP URI address of the ISF.

And step 101c, encapsulating the traditional message user address in the CPM message body by adopting MIME format.

And step 101d, forwarding the CPM message to the ISF according to the SIP URI address of the ISF.

In step 102, before the ISF sets the request-uri field of the CPM message to the relevant address of the IWF, the method further includes:

step 102a, the ISF receives the CPM message, determines an interactive mode between the CPM message and the traditional message according to the address type of the traditional message user address in the CPM message, the message content and the address of the CPM user address, and selects a corresponding traditional message mode to send the CPM message.

In step 102, the ISF sets the request-uri field of the CPM message as the relevant address of the IWF, specifically: the ISF sets the request-URI field to the SIP URI address of the IWF corresponding to the ISF. Here, after completing the setting, the ISF adds an address corresponding to the CPM user and the conventional message service as a second p-asserted-identity field value to the CPM message; and forwarding the CPM message to the IWF according to the SIP URI address of the IWF corresponding to the ISF.

Here, in step 102, before the IWF performs message conversion, the IWF receives the CPM message, acquires the source address of the conventional message according to the second p-asserted-identity field value in the CPM message, and acquires the destination address of the conventional message according to the user address of the conventional message in the CPM message.

The IWF performs message conversion specifically as follows: the IWF further converts the CPM message into a corresponding legacy message according to the legacy messaging service requirements. And then, the IWF sends the traditional message to a corresponding traditional message service system, and the traditional message service system sends the traditional message to a traditional message client to finish the sending of the CPM message from the CPM user to the traditional message user.

Here, when the schematic structural diagram of the service environment architecture shown in fig. 2 is adopted, the present invention mainly includes the following contents:

firstly, a CPM client sends a CPM message to a PF, wherein a target user is a traditional message user.

And secondly, after receiving the message, the PF judges according to the destination user address, namely the traditional message user address, and needs to adopt an interactive mode to transmit the message to the traditional message user, the CPM message is forwarded to the ISF, the request-URI of the CPM message is set as the SIP URI address of the ISF, and the destination user address and the original message content are packaged and stored in a message body by adopting an MIME format.

And thirdly, the SIP/IP Core routes the CPM message to the ISF according to the request-URI, the ISF selects a proper traditional message service for message transmission according to the address type and the message content of the traditional message user address, the address type of the CPM user and the like, after the selection is completed, the ISF takes the SIP URI address of the corresponding IWF as the request-URI address, and takes the address of the CPM user corresponding to the traditional service as a second p-asserted-identity to be added into the message, and sends the CPM message to the SIP/IP Core.

And fourthly, the SIP/IP Core sends the CPM message to the IWF according to the request-uri address, the IWF obtains the source address of the traditional message according to the value of the second p-asserted-identity, obtains the destination address of the traditional message according to the destination address carried in the message body, converts the CPM message into the corresponding traditional message according to the traditional message service requirement, and sends the traditional message to the corresponding traditional message service system.

And fifthly, the traditional message service system sends the traditional message to the traditional message client to finish the sending of the CPM message to the traditional message user.

And step 202, the SIP/CORE forwards the CPM message to the PF to which the CPM client belongs according to the p-asserted-identity field value and the accept-contact field value of the CPM client, and the SIP/IP CORE generates the p-asserted-identity field according to the p-predicted-identity transmitted by the CPM client.

Step 203, the PF learns that the TEL URI address of the destination user does not have a corresponding routable SIP URI address by interacting with the ENUM/DNS, the message needs to be sent by using the conventional message service system, the request-URI is set as the URI address of the ISF, the destination user address is stored in the message body, the destination address and the message body can be encapsulated by using the MIME format, and the PF sends the message to the SIP/IP Core and forwards the message to the ISF by the SIP/IP Core.

Step 204, the ISF obtains an address with the same type as the destination address from the CPM client user configuration information, and uses the address as a second p-asserted-identity field value, and judges that a certain traditional message mode needs to be adopted to send the message to the destination user according to the destination address type and the length of the message body content, then selects an appropriate SIP URI address of the interactive function IWF as a request-URI address, and sends the CPM message to an SIP/IP Core.

And step 205, the SIP/IP Core forwards the CPM message to the IWF according to the request-uri address.

And step 206, the IWF extracts a stored destination address from the message body as a destination address, uses a second p-asserted-identity value as a source address, converts the message content into a short message format, sends the short message format to a short message service system, and forwards the short message service system to the short message client.

Step 207, the short message service system returns a response message to the IWF, and the IWF converts the response message into an SIP protocol format and then sends the SIP/IP Core.

And step 208, the response message is forwarded to the CPM client through the IWF, the ISF, the PF and the like.
