Description

A method of transmitting messages using an internet protocol-based message transport protocol

technical field

The invention relates to the message service realization of Internet protocol (IP) network and mobile communication network, in particular to a method for transmitting messages by using an IP-based message transmission protocol.

Background technique

With the continuous emergence and development of various IP access technologies, for the 3rd Generation Partnership Project (3GPP), the bearer layer will not only be the existing mobile communication network, such as the General Packet Radio Service (GPRS) network or Mobile communication digital cellular mobile communication system (GSM), and other access networks based on packet switching, such as: wireless local area network (WLAN) and code division multiple access (CDMA) 2000 network, etc., here collectively referred to as IP access network . Various applications in mobile communication networks should also be able to be transmitted on these various IP access networks for use by IP users, such as short message service (including SMS and EMS) and multimedia message service (MMS) The business widely used on the mobile communication network needs to consider how to implement it on the IP access network and communicate with the GPRS network.

Fig. 1 is the network frame diagram that supports short message service through the access of IP terminal equipment (UE) in the prior art, including: short message entity (SME) in the network, short message service center (SM-SC), gateway mobile switching center /Short Message-Interworking Function Mobile Switching Center (GMSC/SMS-IWMSC), Charging Gateway Function/Charging Data Function (CGF/CDF) and Home Subscriber Server/Home Location Register (HSS/HLR); IP Access IP Message Gateway (IP-Message-GW), Online Charging System (OCS) and IP UE in the network.

Among them, the IP-Message-GW is used to provide protocol interworking between the IP UE and the mobile communication network, thereby supporting the delivery of short messages and multimedia messages. Between IP-Message-GW and GMSC/SMS-IWMSC, circuit-switched signaling carried on SS7 is used, so for GMSC/SMS-IWMSC, IP-Message-GW is equivalent to the mobile switching center in the mobile communication network (MSC) or GPRS Service Support Node (SGSN), and how to access between MSC or SGSN and GMSC/SMS-IWMSC through circuit switching signaling, and then use SM-SC to realize the transmission of short messages and multimedia messages There are implementations of short messages and multimedia messages in mobile communication networks. The interface between IP-Message-GW and IP UE is R2 interface, through which IP UE implements short message service and multimedia message service, and the registration and authentication of IP UE before implementing short message service and multimedia message service is IP - Functions provided by Message-GW.

SME, SM-SC and GMSC/SMS-IWMSC are functional entities used to implement short message service and multimedia message service in the mobile communication network. SME provides the function of sending and receiving short messages and multimedia messages; SM-SC provides the function of storing short messages and multimedia messages; when terminal equipment (UE) receives short messages, GMSC queries HSS/HLR for routing information through the R5 interface; SMS- The IWMSC provides the authentication function of the UE sending the short message.

HSS/HLR is used to store UE data. In the IP-based message service, the IP UE must register with the IP-Message-GW when it wants to use the message service of the IP-based message transmission protocol. The IP-Message-GW registers its own address and The registration status of the IP UE is notified and stored in the HSS. When the GMSC queries the HSS/HLR for the routing information of the IP UE, the HSS returns the address of the IP-Message-GW to the GMSC.

CGF/CDF users collect and process the offline billing information of UE and IP UE, and then send it to the billing center for processing; OCS is used to collect and process the online billing information of IP UE, and then send it to the billing center for processing .

The following takes the process of the IP UE in the 3GPP TR 23.804v110 standard to realize the process of sending and receiving short message services as an example to illustrate how the IP UE sends and receives short messages and multimedia messages.

Fig. 2 is the signaling flowchart of prior art IP UE sending short message, and its concrete steps are:

Step 200, the IP UE registers with the IP-Message-GW using a general registration procedure.

Step 201, the IP UE sends a message to the IP-Message-GW, the message uses an IP-based message transmission protocol and the message carries the content of the short message and the IP address of the IP UE.

Step 202, IP-Message-GW extracts the content of the short message from the message, and obtains the Mobile Subscriber Integrated Services Digital Network Number (MSISDN) corresponding to the IP address of the IP UE according to the registration information of the IP UE in the HSS/HLR, and constructs a portable The content of the short message and the message of the MSISDN of the IP UE are sent to the SMS-IWMSC, which is based on circuit-switched signaling.

Details of the following procedures for transporting messages based on circuit-switched signaling are defined in TS23.040.

Step 203, SMS-IWMSC forwards the message based on circuit switched signaling to SM-SC.

Step 204, the SM-SC having received the CS signaling sends a message transmission report based on the CS signaling to the SMS-IWMSC.

In step 205, the SMS-IWMSC forwards the message transmission report based on the circuit switching signaling to the IP-Message-GW.

In step 206, the IP-Message-GW performs protocol conversion on the circuit-switched signaling-based message, constructs a message transmission report using an IP-based message transmission protocol, and sends it to the IP UE.

Fig. 3 is the signaling flowchart of prior art IP UE receiving short message, and its specific steps are:

Step 300, the destination IP UE registers with the IP-Message-GW using a general registration procedure.

In step 301, the SM-SC carries the content and information of the short message received from the UE in a message based on circuit-switched signaling, and sends it to the SMS-GMSC.

Steps 302 to 303, SMS-GMSC sends a request message to HSS/HLR to query the routing information of the message, the request message includes an indication that the SMS-GMSC supports the message service using the IP-based message transmission protocol, and HSS/HLR sends SMS-GMSC returns three E.164 addresses: the E.164 address of MSC, the E.164 address of SGSN and the E.164 address of IP-Message-GW.

In step 304, the SMS-GMSC transmits the message according to the obtained address. Here, it is assumed that the E.164 address of the IP-Message-GW is selected to transmit the message based on circuit-switched signaling.

Step 305, IP-Message-GW extracts the content of the short message from the message, obtains the corresponding IP address from the HSS/HLR according to the MSISDN of the destination IP UE, and carries the content of the short message in the message using the IP-based message transmission protocol sent to the destination IP UE.

Step 306: After sending the message using the IP-based message transmission protocol, the IP-Message-GW returns a message transmission report to the SMS-GMSC.

In step 307, the SMS-GMSC returns the status of the message delivery report to the HSS/HLR.

In step 308, the SMS-GMSC returns a message delivery report to the SM-SC.

The process of IP UE receiving and sending multimedia message services is similar to that in Figure 2 and Figure 3, except that the message body carried by the message transmitted using the IP-based message transmission protocol is the message content extracted from the multimedia message.

There are still many processes in the implementation of the message service using the IP-based message transmission protocol to complete the message transmission. Here only the most basic process of initiating message transmission and receiving the message is described. For other processes, please refer to the 3GPP TR 23.804 standard.

As can be seen from the solutions described in Fig. 2 and Fig. 3, when sending and receiving short messages and multimedia messages between the IP UE and the mobile communication network, it is only considered how to pass the circuit-switched signaling from the mobile communication network or based on How to convert the message body carried by the wireless application protocol (WAP) through the protocol in IP-Message-GW, and convert it into a message using an IP-based message transmission protocol and send it to the IP UE, or send the message from the IP access network through the IP bearer How to convert the content of the message in the IP-Message-GW into a message based on circuit switching signaling or WAP and send it to the mobile communication network through protocol conversion. Like this, although can realize the short message between IP UE and mobile communication network and multimedia message sending and receiving, but in actual application, adopt these two methods to realize short message between IP UE and mobile communication network and multimedia message sending and receiving is to exist questionable.

In practical applications, short message service and multimedia message service have existed for a long time, and many applications have been developed on the basis of them. After the IP access network is introduced and the short message service and multimedia message service are implemented on the IP access network, the protocol conversion and transmission of the short message content and multimedia message content by the IP-Message-GW may greatly affect the Various applications in message service and multimedia message service. For example, IP UE needs to use short messages to trigger some applications, but because IP-Message-GW encapsulates messages based on circuit switching signaling using message communication protocols, such as short message information encapsulated by direct transfer application unit (DTAP) The content of the message has been converted into a protocol for transmitting messages in the IP access network, resulting in that the short message information in the message no longer exists or the IP UE needs to reset the trigger logic to realize the original application, which is very important for the IP UE To be honest, the changes are too big.

In addition, in the application of the existing short message service and multimedia message service, such as downloading ringtone pictures and other services, the user needs to input a specific character combination on the UE, and send it to the service provider through the GMSC/SMS-IWMSC. The input combination triggers the corresponding configuration to return the application logic requested by the user. After receiving the application logic, the UE parses and executes it according to the preset rules, so as to obtain the application that the UE wants to download. However, since these are applications based on the expansion of short message service and multimedia message service in mobile communication networks, generally speaking, service providers providing these applications support mobile communication networks, but not necessarily IP access networks , especially in the initial stage of IP access network development, if users use IP UEs, they will not be able to use these short message service applications, which will be detrimental to user experience and the promotion of IP access networks.

To sum up, how to ensure that the information in the short message and multimedia message in the message is not lost when using IP to transmit the message, so that the IP UE that receives the message can trigger the corresponding application to become an urgent problem to be solved.

Detailed ways

In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by giving specific embodiments and referring to the accompanying drawings.

At present, all UEs that want to use the short message service application of the existing mobile communication network should support DTAP, which is used for information exchange between the UE and network entities in the mobile communication network. For the IP UE used by users, if they want to use the application based on the short message service of the existing mobile communication network, then the IP UE must also be able to support DTAP. At present, among the IP UEs used by users, some support DTAP, and some do not support DTAP. That is to say, the support capability of some IP UEs currently used by users can support the short message service of the existing mobile communication network and its application, and the support capability of some IP UE cannot support the short message service of the existing mobile communication network and its application. application.

For the IP UE supporting DTAP, it can identify and analyze the short message content and short message information encapsulated by DTAP, so when the IP-Message-GW sends the message using the IP-based message transmission protocol to the IP UE, it can Carry the short message content and short message information encapsulated by DTAP in the message using the IP-based message transmission protocol, and send it to the IP UE for processing; for the IP UE that does not support DTAP, it cannot process the short message encapsulated by DTAP Therefore, when IP-Message-GW sends a message using the IP-based message transmission protocol to the IP UE, it carries the content of the short message in the message using the IP-based message transmission protocol, and sends Process for IP UE.

For IP-Message-GW, in order to provide short message service applications for IP UEs that support DTAP, and not to restrict the sending and receiving of short messages for IP UEs that do not support DTAP, upon receiving a circuit-switched message from the mobile communication network When receiving a command message, judge whether the destination IP UE can support the encapsulation message communication protocol adopted by the short message carried by the message according to the support capability of the destination IP UE of the message, that is, DTAP, and if so, directly encapsulate the short message using DTAP Send it to the destination IP UE in the message using the IP-based message transmission protocol; otherwise, extract the message content of the short message, carry it in the message using the IP-based message transmission protocol and send it to the destination IP UE.

Similarly, for UEs that want to use the existing mobile communication network multimedia message service applications, they should all support WAP, which is used for information exchange between the UE and network entities in the mobile communication network.

For IP-Message-GW, in order to provide the application of multimedia message services to IP UEs supporting WAP, and not to restrict the sending and receiving of multimedia messages to IP UEs that do not support WAP, when receiving WAP-based messages from the mobile communication network According to the support capability of the destination IP UE of the message, it is judged whether the destination IP UE can support the encapsulation message communication protocol adopted by the multimedia message carried in the message, that is, WAP. If yes, the multimedia message is directly encapsulated in the IP-based message The message of the transmission protocol is sent to the destination IP UE; otherwise, the message content of the multimedia message is extracted, carried in the message using the IP-based message transmission protocol, and sent to the destination IP UE.

Regardless of whether the short message constructed by DTAP or the multimedia message constructed by WAP is used as the message body in the message using the IP-based message transmission protocol, when the message is sent to the destination IP UE, the message body should be added to the message header The type description, which is determined according to the message protocol used to encapsulate the message body. For example, when using the short message constructed by DTAP in the message of the IP-based message transmission protocol as the message body, the message body type description in the message header can be short message service and its application or DTAP; using IP-based message transmission When a WAP-structured multimedia message is used as a message body in a message of the protocol, the type description of the message body in the message header can be a multimedia message service and its application or WAP.

Fig. 4 is the flow chart of the method for IP UE receiving short message or multimedia message of the present invention, and its concrete steps are:

Step 401, IP-Message-GW receives a message based on circuit switched signaling or WAP, the message carries a short message or multimedia message encapsulated with a message communication protocol sent to the destination IP UE and the MSISDN of the destination IP UE, the The message communication protocol may be DTAP used by the short message service application of the mobile communication network, or WAP used by the multimedia message application of the mobile communication network.

Step 402, IP-Message-GW determines the support capability of the destination IP UE according to the MSISDN of the destination IP UE carried in the message.

In practical applications, depending on the query mechanism, MSISDN may be used, or a Telephone Uniform Resource Identifier (TEL URI) composed of MSISDN may be used to query the support capability of the specified IP UE.

Step 403, IP-Message-GW judges whether to support the short message service application or the multimedia message service application of the mobile communication network according to the support capability of the destination IP UE, if yes, perform step 406; otherwise, perform step 404.

Step 404, IP-Message-GW extracts the message content from the short message or multimedia message encapsulated with the message communication protocol carried by the message, carries the message content in the message using the IP-based message transmission protocol, and sends it to the destination IP UE .

The IP-Message-GW can query the local database according to the MSISDN of the destination IP UE carried in the message, and obtain the corresponding IP address.

Certainly, the present invention can also be different to the addressing mode of destination IP UE according to the difference of the message communication protocol based on IP used, can not adopt the IP address of destination IP UE to address, but use IP Multimedia Subsystem (IMS ) in the Session Initiation Protocol (SIP) routing mechanism for addressing.

Step 405, after receiving the message, the destination IP UE reads the content of the message.

Step 406, IP-Message-GW carries the short message or multimedia message encapsulated with the message communication protocol and the type description of this message in the message using the IP-based message transmission protocol, and sends it to the destination IP UE.

When a message communication protocol is used to encapsulate a multimedia message, the message communication protocol is WAP.

When the short message is encapsulated by the message communication protocol, the message communication protocol is DTAP.

Similarly, the IP-Message-GW can query the local database according to the MSISDN of the destination IP UE carried in the message to obtain the corresponding IP address.

According to the different message communication protocols used for encapsulation, the addressing mode of the destination IP UE can also be different, and the IP address of the destination IP UE can not be used for addressing, but the SIP routing mechanism in the IMS can be used for addressing.

Step 407, after the destination IP UE receives the message, first use the IP-based message transmission protocol to parse out the message body encapsulated by the message, that is, the short message or multimedia message encapsulated by the message communication protocol, and then describe it according to the type carried by the message Analyze the short message or multimedia message encapsulated by the message communication protocol, obtain the message content and the information in the message header, and trigger the application of the corresponding message service according to the message content and the information in the message header.

In order to realize the processing described in FIG. 4, in step 402, the IP-Message-GW must be able to obtain the support capability of the destination IP UE. In order to solve this problem, there are various solutions.

In the first solution, when the IP UE registers with the registration server of the IP access network, it carries its own support capability in the registration message, that is, whether it supports the short message service and its application of the mobile communication network or the multimedia message service and its application. application. This can be realized by extending the registration message in the prior art. When the IP-Message-GW wants to obtain the support capability of the IP UE, it can be obtained from the registration server through third-party registration or subscription/notification (SUBSCRIBF/NOTIFY). When the bearer network of the IP access network is IMS, the registration server is a Serving Call Control Function (S-CSCF).

In the second solution, before the IP UE initiates the short message service interaction, the IP UE interacts with the application server that stores the IP UE support capability in the IP access network, and stores its own support capability in the application server. The Message-GW obtains the support capability of the IP UE by querying the application server.

The third solution, the solution depends on the operator's strategy and configuration. When an operator assigns a number to an IP UE, it corresponds the type of the assigned number to the support capability. For example, the support capability corresponding to the E.164 number is that the UE supports the short message service application of the mobile communication network. In this way, the IP-Message-GW can determine the support capability corresponding to the number that the IP UE has according to the mapping relationship, thereby obtaining the support capability that the IP UE has. All the numbers owned by the IP UE are stored in the HSS/HLR, and when the IP-Message-GW wants to obtain all the numbers owned by the IP UE, it can be obtained by querying the HSS/HLR. However, this solution has many limitations and cannot guarantee 100% accuracy. This is because many wireless local area network (WLAN) UEs with MSISDNs (MSISDNs are constructed using E.164 numbers) may only use MSISDNs for voice services , does not necessarily support the mobile communication system short message service and its application or multimedia message service and its application. At this time, it may also be considered to allocate the E.164 number according to the number segment, so as to determine whether the terminal using the number supports the above-mentioned capability by identifying the number segment to which a certain number belongs.

Fig. 5 is the signaling flowchart that IP UE of the present invention receives short message, and its specific steps are:

Step 500, the destination IP UE registers with the IP-Message-GW using a general registration procedure.

Step 501, the SM-SC carries the short message received from the UE in a message based on circuit-switched signaling and sends it to the SMS-GMSC. The short message includes the short message content and short message information, and the message also carries the purpose MSISDN of the IP UE.

Steps 502 to 503, SMS-GMSC sends a request message to HSS/HLR according to the MSISDN of the destination IP UE carried in the message to inquire about the routing information of the message based on circuit switched signaling, and the request message includes a message indicating that the SMS-GMSC supports Indication of message service using IP-based message transfer protocol, HSS/HLR returns three E.164 addresses to SMS-GMSC: E.164 address of MSC, E.164 address of SGSN and E.164 address of IP-Message-GW. 164 addresses.

In step 504, the SMS-GMSC transmits the message based on the circuit-switched signaling according to the obtained address. Here, it is assumed that the E.164 address of the IP-Message-GW is selected to transmit the message.

Step 505, IP-Message-GW determines the support capability of the destination IP UE according to the MSISDN of the destination IP UE carried in the message.

Step 506, IP-Message-GW judges whether this purpose IPUE supports the short message service of mobile communication network and its application according to the support ability of this purpose IP UE, if yes, execute step 508; Otherwise, execute step 507.

Step 507, IP-Message-GW extracts the short message content from the short message carried by the message with DTAP encapsulation, carries the short message content in the message using the IP-based message transmission protocol, according to the IP address of the destination IP UE or According to the identification of the destination IP UE, it is sent to the destination IP UE through the SIP route. After receiving the message, the destination IP UE reads the content of the short message and proceeds to step 509.

Step 508, IP-Message-GW extracts the carried short message encapsulated with DTAP from the message, carries the short message encapsulated with DTAP and the type description of this message in the message using the message transmission protocol based on IP, according to The IP address of the destination IP UE or the identity of the destination IP UE is sent to the destination IP UE. After the destination IP UE receives the message using the IP-based message transmission protocol, it first uses the IP-based message transmission protocol to parse out the information encapsulated in the message. The message body is the short message encapsulated by DTAP, and then analyze the short message encapsulated by DTAP according to the type description carried by the message, obtain the message content and the information in the message header, and make corresponding actions according to the message content and the information in the message header application of the message service, go to step 509.

Step 509: After the IP-Message-GW sends the message using the IP-based message transmission protocol, it returns a message transmission report to the SMS-GMSC.

Step 510, the SMS-GMSC returns the status of the message delivery report to the HSS/HLR.

Step 511, the SMS-GMSC returns a message delivery report to the SM-SC.

How to realize the application of mobile communication network short message when IP UE sends short message in detail below.

For the IP UE supporting the short message service and its application, the present invention can not only send the message using the IP-based message transfer protocol carrying the short message content, but also send the message carrying the IP-based message transfer protocol encapsulated by DTAP. information. Considering some requirements in short message service applications, such as downloading ringtone pictures and other services, the user needs to enter a specific character combination on the terminal, and at the same time fill in a number specified by the service provider in the destination number to achieve. The purpose number here is also allocated by the existing mobile communication network. The GMSC/SMS-IWMSC and SM-SC in the circuit switching network send the short message to the corresponding service provider according to the purpose number. The input combination triggers the corresponding configuration to return the application logic requested by the user. After receiving the application logic, the user terminal parses and executes it according to the preset rules, so as to obtain the application that the user wants to download. Therefore, if the IP UE wants to use the same service in the IP network, it sends a specific character combination to the specified service provider through IP-Message-GW and GMSC/SMS-IWMSC, that is, a specific destination number to request a When applying, it is necessary to construct a short message encapsulated in DTAP, carry the short message encapsulated in DTAP and its type description in a message using an IP-based message transmission protocol, and transmit it to the IP-Message-GW, and the IP-Message-GW according to the The type description carried by the message is determined to directly fill the DTAP-encapsulated short message carried by the message into a complete circuit-switched signaling-based message and send it to GMSC/SMS-IWMSC, which will be used by GMSC/SMS-IWMSC as an existing The message based on the circuit switching signaling is processed and sent to the SM-SC, and then the SM-SC sends it to the service provider for further processing according to the destination number.

In this implementation, the IP UE first constructs a short message encapsulated in DTAP according to the application implementation mechanism of the short message service in the mobile communication network. Part of the information in the short message, such as the location relationship information between the IP UE and the mobile communication network, if If it cannot be obtained, it may not be filled, and the part that can be filled, such as the destination number, is filled according to the usage in the existing mobile communication network. Secondly, the IP UE sends the short message encapsulated with DTAP and the type description to the IP-Message-GW in the message using the IP-based message transmission protocol. Finally, IP-Message-GW obtains the DTAP-encapsulated short message carried in the message according to the type description carried in the message, fills in the part of the information that is not filled in the short message, and sends it to the GMSC/ The SMS-IWMSC then sends it to the SM-SC, and the SM-SC sends it to the service provider for processing.

In the message using the IP-based message transmission protocol, the short message constructed by DTAP is used as the message body. When the message is sent from the IP UE to the IP-Message-GW, the type description of the message body should be added in the message header. The type description is determined according to the support capability of the IP UE. For example, when the IP UE supports DTAP, the message body type description in the message header can be short message service and its application or DTAP.

Fig. 6 is the signaling flowchart that IP UE of the present invention sends short message, and its concrete steps are:

Step 600, the IP UE registers with the IP-Message-GW using a general registration procedure.

Step 601, the IP UE sends a message using an IP-based message transmission protocol to the IP-Message-GW, the message carries a DTAP-encapsulated short message and a type description, and the short message includes short message content and short message information.

Step 602, IP-Message-GW determines to extract the DTAP-encapsulated short message from the message according to the type description carried in the message, and according to the registration information of the IP UE in the HSS/HLR, the IP address of the IP UE or the address of the destination IP UE Identify the corresponding MSISDN obtained, construct a DTAP-encapsulated short message and send it to the SMS-IWMSC according to the MSISDN of the IP UE using a circuit-switched signaling-based message.

Step 603, SMS-IWMSC forwards the message to SM-SC.

Step 604, SM-SC sends a message delivery report to SMS-IWMSC.

Step 605, SMS-IWMSC forwards the message transfer report to IP-Message-GW.

Step 606: The IP-Message-GW performs protocol conversion on the message delivery report based on the circuit switching signaling, constructs a message delivery report using an IP-based message delivery protocol, and sends it to the IP UE.

When the IP UE receives the message, the present invention considers that if the short message encapsulated by the circuit switching signaling is a longer message, and the length of the longer message exceeds what the IP-based message transmission protocol can support in one message transmission Maximum transmission unit (MTU), for this kind of short message that cannot be transmitted using an IP-based message transmission protocol message, IP-Message-GW has two processing methods: one is for the short message encapsulated by circuit switching signaling Carry out segmentation, and then transmit through SIP MESSAGE; the other is to use the MSRP protocol. If the MSRP protocol is used, the basic process is: establish a session between the IP-Message-GW and the destination IP UE through the SIP protocol, and negotiate the resources required to transmit messages using MSRP. The message content is transmitted between IP-Message-GW and the destination IP UE as a media stream, and the session is deleted after the transmission is completed.

When the IP UE sends a message, the present invention will consider whether the short message encapsulated through DTAP in the message of the IP-based message transmission protocol exceeds the message length that can be transmitted by a circuit-switched signaling message. If it exceeds, the IP-Message-GW This message needs to be segmented so that the DTAP-encapsulated short message completely encapsulated in the message of the IP-based message transfer protocol can be sent to the mobile communication network with multiple short messages encapsulated based on circuit-switched signaling Terminal UE; if it does not exceed, it will be processed according to the normal processing procedure.

In the present invention, for some IP UEs, its support capability can not only support mobile communication network short message and its application, that is, support DTAP, but also support mobile communication network multimedia message and its application, that is, support WAP.

Since multimedia messages and their applications are encapsulated by WAP, when IP-Message-GW receives a WAP-based message carrying a WAP-encapsulated multimedia message, it judges whether the destination IP UE is To support WAP, if so, directly construct a message using an IP-based message transmission protocol, and the message carries a WAP-encapsulated multimedia message and sends it to the destination IP UE; otherwise, extract the message content in the WAP-encapsulated multimedia message of the message, and convert The message content is carried in the message using the IP-based message transmission protocol and sent to the destination IP UE.

In the message using the IP-based message transmission protocol, the multimedia message constructed by WAP is used as the message body. When the message is sent from the IP UE to the IP-Message-GW, the type description of the message body should be added in the message header. The type description is determined according to the support capability of the IP UE. For example, when the IP UE supports WAP, the message body type description in the message header can be multimedia message service and its application or WAP.

A specific example is given below to illustrate how the IP UE of the present invention implements the application of multimedia messages.

Fig. 7 is the signaling flowchart of the IP UE receiving multimedia messages in the present invention, assuming that the bearer layer of the IP UE is an IMS network, and the network entities involved include: S-CSCF, IP-Message-GW, SM-SC/ in the IMS network IWMSC, MMS Relay/Server and HLR/HSS, wherein, SM-SC/IWMSC, MMS Relay/Server and HLR/HSS are network entities in the existing mobile communication network (such as GPRS network), and its specific steps are:

Step 700, the IP UE registers in the IMS network.

Steps 701-704, there is a multimedia message that needs to be received by the IP UE in the mobile communication network, and the mobile communication network sends a notification to the IP-Message-GW in the form of a short message, and the short message carries a multimedia message identifier (MMS) for storing the multimedia message. ID) and the MSISDN of the IP UE.

UE in the mobile communication network sends notifications to IP-Message-GW through MMS Relay/Server and SM-SC/IWMSC in turn.

Steps 705-708, IP-Message-GW queries the HSS/HLR according to the MSISDN of the IP UE carried in the message, obtains the corresponding IP address or directly constructs the IP UE identifier required for SIP routing; IP-Message-GW according to the message The MSISDN of the destination IP UE carried determines the support capability of the IP UE; the IP-Message-GW sends the IP-based message transmission protocol carrying the MMS ID to the IP UE through the S-CSCF according to the IP UE's IP address or the IP UE's identity. Notification message, the IP UE returns a response to the notification message through the S-CSCF, that is, SIP 200 OK.

In steps 709-711, the IP UE sends a message for obtaining a multimedia message to the IP-Message-GW through the S-CSCF, and the message uses an IP-based message transmission protocol.

Step 712, IP-Message-GW according to the manner defined in 3GPPTS23.140 protocol to the multimedia message relay server with MMS ID, that is, MMS Relay/Server to obtain the multimedia message, the multimedia message includes multimedia message content and multimedia message information.

Step 713, IP-Message-GW judges whether the IP UE supports WAP according to the support capability of the IP UE, if yes, proceed to step 715, otherwise, proceed to step 714.

Step 714, IP-Message-GW extracts the multimedia message content from the multimedia message, carries the multimedia message content in the message using the IP-based message transmission protocol, and sends it through the SIP route according to the IP address of the IP UE or according to the identification of the destination UE For the IP UE, after receiving the message using the IP-based message transmission protocol, the IP UE reads the content of the multimedia message and proceeds to step 716.

Step 715, IP-Message-GW performs WAP encapsulation of the multimedia message, carries the WAP-encapsulated multimedia message and the type description of the IP UE in the message using the IP-based message transmission protocol and sends it to the IP UE, and the IP UE receives the After using the message of the IP-based message transmission protocol, first use the IP-based message transmission protocol to parse out the message body of the message, and then use the type description carried in the message to parse the multimedia message encapsulated in WAP to obtain the message content and message According to the information in the header, apply the corresponding message service according to the message content and the information in the message header, and then go to step 716.

In steps 716-717, the IP-Message-GW returns a confirmation message to the IP UE through the S-CSCF.

Similarly, the IP UE of the present invention can also send a multimedia message, and the sending method is similar to the method described in FIG. -Message-GW, the message carries the WAP-encapsulated multimedia message and type description; in step 602, the IP-Message-GW determines to extract the WAP-encapsulated multimedia message from the message according to the type description carried by the message Filling the multimedia message encapsulated by WAP using the WAP protocol in the existing mobile communication network according to the MSISDN of the IP UE to send the multimedia message to the multimedia message server.

Considering some requirements in the application of the multimedia message service, the user needs to enter a specific character combination on the terminal, and at the same time fill in a number specified by the service provider in the destination number to achieve. The purpose number here is also allocated by the existing mobile communication network. The multimedia message server in the existing mobile communication network sends the multimedia message to the corresponding service provider according to the purpose number, and the service provider triggers the corresponding service according to the input combination of the IP UE. configuration to return the application logic requested by the user. After receiving the application logic, the user terminal parses and executes it according to preset rules, thereby obtaining the application that the user wants to download. Therefore, if the IP UE wants to use the same service in the IP access network, it sends a specific character combination to the specified service provider through the IP-Message-GW and the multimedia message server to request a When applying, it is necessary to construct a multimedia message encapsulated with WAP, carry the multimedia message encapsulated with WAP and its type description in a message using an IP-based message transmission protocol, and send it to IP-Message-GW, and IP-Message-GW according to the The type description carried by the message is determined to directly fill the WAP-encapsulated multimedia message carried by the message into a complete WAP-based message and send it to the multimedia message server, and the multimedia message server will treat it as an existing WAP-based message. , and then the multimedia message server sends it to the service provider for further processing according to the destination number.

In this implementation, the IP UE first constructs a multimedia message encapsulated by WAP according to the application implementation mechanism of the mobile communication network multimedia message service. Part of the information in the multimedia message, such as the location relationship information between the IP UE and the mobile communication network, if If it cannot be obtained, it may not be filled, and the part that can be filled, such as the destination number, is filled according to the usage in the existing mobile communication network. Secondly, the IP UE transmits the WAP-encapsulated multimedia message and the type description to the IP-Message-GW in a message using an IP-based message transmission protocol. Finally, the IP-Message-GW obtains the WAP-encapsulated multimedia message carried by the message according to the type description carried by the message, fills in the unfilled part of the information in the multimedia message, and sends the WAP message to the multimedia message server. The message server sends it to the service provider for processing.

When the IP UE receives the message, the present invention considers that if the multimedia message encapsulated by WAP is a longer message, and the length of the longer message exceeds the MTU that the IP-based message transmission protocol can support in a message transmission, for The IP-Message-GW has two processing methods for this multimedia message that cannot be transmitted using an IP-based message transmission protocol message: one is to segment the multimedia message encapsulated in WAP, and then transmit it through SIP MESSAGE; the other One is to use the MSRP protocol. If the MSRP protocol is used, the basic process is: establish a session between the IP-Message-GW and the destination IP UE through the SIP protocol, and negotiate the resources required to transmit messages using MSRP. The message content is transmitted between IP-Message-GW and the destination IP UE as a media stream, and the session is deleted after the transmission is completed.

When the IP UE sends a message, the present invention will consider whether the WAP-encapsulated multimedia message in the message of the IP-based message transmission protocol exceeds the message length that can be transmitted by a WAP message. If it exceeds, the IP-Message-GW needs to check this The multimedia message is segmented, so that the WAP-encapsulated multimedia message completely encapsulated in the message of the IP-based message transmission protocol can be sent to the destination UE in the mobile communication network with multiple WAP-based multimedia messages.

The supporting capability of the IP UE of the present invention may be to support the short message service and its application of the mobile communication network or/and support the multimedia message service and its application of the mobile communication network.
