Description

Message interworking gateway and method for message transmission in IP-based message service

The present invention relates to the field of communications, and in particular, to a message interworking gateway and a method for message transmission in an IP (Internet Protocol) based message service.

Background technique

With the rapid development of the Internet (Internet), IP has occupied a dominant position in various terminal applications. In the future, the mainstream of network development is likely to be IP. How to transmit IP data more efficiently, at high speed and cheaply is the future research of telecommunication networks. Focus.

3GPP (Third Generation Partnership Projects) is a collaborative group of telecommunications standards departments from China, Japan, Korea, the United States, and Europe. Including more than 200 wireless vendors and operators worldwide. With the continuous emergence and development of various IP access technologies, for 3GPP, the bearer layer will not only be an existing GPRS (General Packet Radio Service) network, but also include other IP-based technologies. Access technology networks such as WLAN (Wireless LAN), GERAN (Global System for Mobile Communications / Enhanced Data Rates for Global Evolution Radio Access Network, GSM/EDGE Radio Access Network), WiMAX (World Interoperability for Microwave Access) , Global Interactive Microwave Access), CDMA2000 (Code Division Multiple Access 2000), etc. These networks based on IP access technologies are collectively referred to as Universal IP Access.

Various applications of the existing mobile network, such as SMS (Short Message Service), EMS (Enhanced Message Service), and MMS (Multimedia Message Service), are in existing mobile Services that are widely used on the network need to consider how to implement them on various IP-based access networks and interwork with existing networks. The function of implementing the message service in the network based on the IP access technology is shown in Figure 1. The functions of the functional entities included in Figure 1 are described below.

IP-Message-GW (IP-Message-Gateway) is a new functional entity for IP access technology. It is used to implement IP access technology-based networks and GSM (Global System for Mobile Communications) / GPRS networks. Inter-communication between the two protocols, thus realizing short messages in The transfer between the IP access technology network and the GSM/GPRS network.

IP-Message-GW and GMSC/SMS-IWMSC (Gateway Mobile Switching Center, SMS-InterWorking Mobile Switching Centre, short message service interworking mobile switching center) are used between SS7 (Signaling System No. 7) MAP (Mobile Application Part) protocol, for GMSC/SMS-IWMSC, IP-Message-GW is equivalent to existing MSC (Mobile Switching Centre) or SGSN (Serving GPRS Supporting) Node, GPRS service support node). Therefore, the IP-Message-GW can implement interworking between the IP-based message service and the existing short message service through its R6 interface with the GMSC/SMS-IWMSC.

The IP-Message-GW also enables the IP terminal accessing the 3GPP network to use the existing short message service through its R2 interface with the IP terminal, where the IP terminal can access the 3GPP network in a variety of ways. of. In the IP-based short message service, the user must use the IP-based short message service to register with the IP-Message-GW, and the registration and authentication of the user using the short message service is also a function of the IP-Message-GW.

SME (Short Message Entity). SM-SC (Short Message - Serving Center) and GMSC/SMS-IWMSC are functional entities used in the implementation of short message services in existing mobile networks. The SME is responsible for receiving and sending short messages; the SM-SC is used to store short messages; and the GMSC is used by the terminal to receive short messages to the HSS/HLR (Home Subscriber Server/Home Location Register, Home Subscriber Server/Home Location Register) Query routing information; SMS-IWMSC is used to authenticate the terminal when the terminal sends a short message. Generally speaking, the short message service is jointly implemented by three functional entities: SME, SM-SC and GMSC/SMS-IWMSC.

HSS/HLR is generally used to save subscriber data. In addition, the HSS also stores the IP-Message-GW address and the user's registration status. When the SMS-GMSC queries the HSS/HLR for the short message routing information of the user, the HSS returns the address of the IP-Message-GW to the SMS-GMSC.

The CGF/CDF (Charging Gateway Function/Charging Data Function) is used to collect and process the billing information of the user's offline charging. The bill information is then sent to the billing center for processing. The OCS (Online Charging System) is used to collect and process the bill information of the user's online billing, and then send the bill information to the billing center for processing.

In the prior art, in the network based on the IP access technology, the message transmission process initiated by the UE (User Equipment) supporting the IP access is as shown in FIG. 2, and includes the following steps: Step 21: The user registers with the IP -Message-GW.

To use message services in a network based on IP access technology, the UE must first register with the IP-Message-GW.

Step 22. The user sends a message.

The UE sends a message to be transmitted to the IP-Message-GW, where an existing IP-based messaging method can be used.

Step 23. The IP-Message-GW forwards the message content.

The IP-Message-GW extracts the received short message content, obtains the MSISDN (Mobile Station Integrated Service Data Network) corresponding to the IP address of the user from the local database, and constructs a standard MAP signaling, and the message is The content and MSISDN are sent to the SMS-IWMSC. The details of the message procedure in which MAP is used are defined in TS 23.040.

Step 24. The SMS-IWMSC forwards the message.

The SMS-IWMSC forwards the received message to the SM-SC.

Step 25. The SM-SC sends a message transmission report.

After receiving the message forwarded by the SMS-IWMSC, the SM-SC sends a message delivery report to the SMS-IWMSC.

Step 26. SMS-IWMSC sends a message delivery report

After receiving the message transmission report forwarded by the SM-SC, the SMS-IWMSC sends a message to the IP-Message-GW.

Step 27. Send a message delivery report to the user.

The IP-Message-GW constructs a message transmission report according to the IP-based message transmission method supported by the user, and transmits the message transmission report to the UE.

In the prior art, a UE (User Equipment) supporting IP access receives a message transmission process. As shown in Figure 3, the following steps are included:

Step 31: The user registers with the IP-Message-GW.

The UE must register with the universal registration process before receiving the message.

IP-Message-GW.

Step 32: The SM-SC forwards the message.

The SM-SC forwards the saved message to the SMS-GMSC:.

Step 33: The SMS-GMSC queries the HSS/HLR for routing information.

After receiving the message forwarded by the SM-SC, the SMS-GMSC sends a request message to the HSS HLR to query the routing information of the message, including an indication indicating that the SMS-GMSC supports the IP message service, according to the indication, the HSS/HLR Return three E.164 addresses: MSC's,

SGSN, and IP-Message-GW.

Step 34: The SMS-GMSC forwards the message.

Based on the three addresses obtained, the SMS-GMSC can transmit the message through any of the addresses, assuming that the message is selected to be transmitted over the IP, so the message is transmitted to the IP-Message-GW in the form of standard MAP signaling.

Step 35: Send a message to the user.

After receiving the message forwarded by the SMS-GMSC, the IP-Message-GW extracts the message content, obtains the IP address corresponding to the user from the local database according to the MSISDN of the destination user, and then uses the IP-based message transmission protocol. The message content is sent to the UE.

Step 36: The IP-Message-GW returns a message transmission report.

After transmitting the message to the UE, the IP-Message-GW returns a message transmission report to the SMS-GMSC.

Step 37: The SMS-GMSC sends a message delivery report status.

The SMS-GMSC sends a message delivery report status to the HSS/HLR.

Step 38: SMS-GMSC returns a message delivery report

The SMS-GMSC returns a message delivery report to the SM-SC.

There are still many processes in the implementation of the existing IP-based message service to complete the message transmission. Only the most basic process of initiating message transmission and receiving messages is described. For the rest of the process, please refer to the process.

TR23.804. The disadvantages of the transmission process of the existing IP-enabled UEs for transmitting and receiving messages are as follows: the message service based on the IP network and the traditional implementation by GSM/GPRS in the process of sending and receiving messages in the prior art The differences between messaging services are not considered enough.

Short message service based on traditional message service (GSM/GPRS), when using standard MAP signaling to transmit messages, due to the limitation of MAP signaling format, there are some requirements on the length and format of the message, such as for each short Messages, the English letters that can be transmitted do not exceed 140 or 160 characters, or the Chinese characters do not exceed 70 characters. If the content of the message is large, multiple messages can be connected, so that the longest message can be transmitted over 34,000 words. Section. In terms of supported formats, only content in a specified format such as text, pictures, animations, sounds, etc. can be transmitted, other formats are not supported, and the like. There are similar restrictions in the multimedia messaging service.

The message service based on IP is much wider than the message length. In theory, the message size of a UDP (User Datagram Protocol) packet can be transmitted by a message. The current length is It has not been determined yet, but it can support at least 1300 bytes. This length is generally sufficient to meet the message length requirements in the use of existing short message services. At the same time, the message service based on IP does not have such strict restrictions on the format of the message, and any media type can be transmitted as long as the receiving terminal supports the media format.

Therefore, when implementing the IP-based message service, if the characteristics of the IP network are not considered, the existing message service is converted on the EP-Message-GW, and the IP-based message transmission protocol is used for transmission. The resources of the IP network are a great waste, especially in the air interface part of the waste of air. Because for the GSM/GPRS network, a message exceeding the MAP signaling length requirement needs to be transmitted into multiple messages that meet the length requirement, so multiple messages need to be sent to implement the transmission of the longer message, and for the IP network. Said that the length limit can be said to be much looser, it is possible to transmit this long message with one or several signaling messages, even if a message of 34,000 bytes is sent by connecting more than two hundred short messages, When transmitting in an IP network, it is possible to transmit with more than 20 IP-based messages (SIP MESSAGE), or establish a SIP session for it, and use an MSRP data stream to transmit, thus greatly saving the network. Resources and air interface resources. Now The difference is not considered in the prior art. In the IP network, a plurality of signaling messages are used to transmit the longer message, thereby causing waste of IP network resources and air interface resources. Similarly, IP networks can support multiple media formats, but only existing text services can support text, pictures, animations, sounds, etc. Therefore, IP-Message-GW must be able to detect and handle this kind of information. The impact of the difference on the existing message service, otherwise it is easy to generate errors. For example, IP-Message-GW transmits the media format that is not supported by the GSM/GPRS message service to the GSM/GPRS network by using standard MAP signaling as a message. The terminal, the terminal will generate garbled characters because it does not recognize this format, which has a bad influence on the user's use, and is also a waste of GSM/GPRS network resources.

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a message interworking gateway and a method of messaging in an IP based messaging service. The core of the invention is: According to IP-based messaging services and GSM/GPRS-based The difference between the message length and the format of the interest service, the length and format conversion of the message sent by the user on the IP-Message-GW, and then the processed message is sent to the destination user.

The invention first needs to set a message interworking gateway in the IP message gateway IP-Message-GW. The structure diagram of the message interworking gateway is as shown in FIG. 8, and includes an IP message processing module, an interworking processing module, and a second generation communication network message processing. Module, where:

The IP message processing module is connected between the IP network and the interworking processing module, and is configured to receive and send an IP message;

The interworking processing module is connected between the IP message processing module and the second generation communication network message processing module, and is configured to perform conversion processing of data difference between the IP message service and the second generation communication network message service;

The second generation communication network message processing module is connected between the second generation communication network and the interworking module for receiving and transmitting the second generation communication network message.

The IP-Message-GW of the present invention adopts different processing methods according to different message services adopted by the sender and receiver. The following describes the processing method in two cases, Case 1 and Case 2. The specific description is as follows:

Case 1. The terminal UEo initiates the transmission of the message using the conventional message service (message service based on GSM/GPRS), and the terminal UEt uses the IP-based message service reception.

In this case, after receiving the message transmitted by the MAP signaling from the SMS-GMSC, the IP-Message-GW needs to perform certain processing on the message, and then send the message to the user. The specific processing flow is shown in FIG. . Including the following steps:

Step 4-1: The IP-Message-GW receives the MAP signaling.

After receiving the MAP signaling sent by the SMS-GMSC to the SMS-GMSC, the IP-Message-GW extracts the message content according to the signaling. Then, go to step 4-2.

Step 4-2. Determine whether the message is a complete message.

The IP-Message-GW determines whether the message is a complete message according to the extracted message content, and if yes, performs step 4-3; otherwise, performs step 4-4.

Step 4-3: The IP-Message-GW converts the message carried by the MAP signaling, and then uses the IP-based message transmission mode to transmit. If the IP-Message-GW determines that the message is a complete message, according to the prior art, the message receiving process flow shown in FIG. 3 is continued, and the IP-Message-GW sends the message content to the IP-based message transmission protocol. Purpose UEt.

Step 4-4, cache the message and set a predetermined condition.

If the IP-Message-GW determines that the message is not a complete message, but a piece of content after a longer message is segmented, the IP-Message-GW does not immediately transmit the message using the IP-based message transfer protocol. And buffering the message, setting a predetermined condition, and determining whether the predetermined condition is satisfied, the predetermined condition may be that the IP-Message-GW receives the last segmentation message in the message transmitted by the segment, or is based on In the IP message service, the length of the message after combining these segments has reached the maximum message length that the IP message protocol can support.

In practical applications, a timer can also be started, and the duration of the timer is set to ensure that the longer message segmented under normal conditions can be completely transmitted to

IP-Message-GW. Then, perform steps 4-5.

Step 4-5: After the predetermined condition is met, the received messages are merged and sent to the destination user by using an IP-based transmission method.

If the IP-Message-GW receives subsequent segmentation messages belonging to the longer message before the predetermined condition is met or before the set timer expires, the received message is cached.

After the predetermined condition is satisfied or after the set timer expires, if the IP-Message-GW confirms that the segmented longer message has been received all, the IP-Message-GW combines the segmented messages into one message. The content of the message is sent to the destination UEt using an IP-based transport protocol, and the timer is cleared.

The message segmentation described in the present invention may be a message content part of a segmented short message, or may be a segmented short message itself, specifically combined and encapsulated in an IP-based message transmission protocol message. Which type is in the message body depends on the content encapsulated by the message body at the IP message gateway. The IP message gateway can decide to encapsulate the message content in the message body or directly encapsulate the short message itself.

If the predetermined condition is satisfied or after the set timer expires, the IP-Message-GW confirms that the segmented longer message is not received all, and the Bay ij IP-Message-GW can select The appropriate failure deliver report is returned to the SMS-GMSC, and no message is sent to the destination UEt.

The IP-Message-GW may also choose to directly send the received message content to the destination UEt, and subsequently perform the processing according to the above manner after receiving other segmentation messages belonging to the longer message, that is, if it is the last segment of a message, If yes, the timer is continued, and all the segmented messages received are combined and sent to the destination user after the timer expires until all the longer messages are sent to the destination user.

There is also a simple implementation, that is, the IP message gateway waits until the last segmentation message of the longer message content is received, and then combines a SIP MESSAGE to the IP terminal because the message service is reliably transmitted, but the delay is not guaranteed. . Here, the IP message gateway also starts a timer, but the condition for clearing the timer is that the last segment is received or not received within the time specified by the operator, for example, according to the time of the SM-SC, 24 hours. The last segment is cleared and the previously saved segments are not sent. Alternatively, a reasonable timer duration can be set according to the validity time of the message in the received short message, ensuring that the segmentation message is retained at the IP message gateway for more than the valid time of the message. Or the IP message gateway finds that the length of the message after combining the segments in the IP-based message service has reached the maximum message length that the IP message protocol can support. In this case, the message that has been combined is also sent to the SIP MESSAGE. The IP terminal then combines the subsequent received segmentation messages into a new SIP MESSAGE message for transmission.

Another method is that the DP message gateway receives other segmentation messages that belong to the content of the longer message, and the IP message gateway finds that the previous segment is not saved, indicating that the segmentation has been sent, then the subsequent segmentation messages may be followed. Send a single message.

Another method is to establish a SIP (Session Initiated Protocol) session between the IP-Message-GW and the user equipment UE that accepts the message, and then use MSRP (Message Session Relay Protocol). The protocol transmits the received segmentation message until all segmentation messages have been sent, releasing the SIP session. The disadvantage of this method is that it increases the session establishment process, increases the interaction time, and also takes more resources.

A processing flow based on the SIP session method is: IP message gateway receives the use of tradition When the message sent by the message service is first checked whether the message is a complete message, if yes, it is processed according to the existing implementation. If not, that is, the message is part of a longer message, then the IP message gateway further determines Whether the length of the longer message is less than or equal to a maximum message length using an IP-based message transmission protocol, such as the maximum message length that the SIP MESSAGE can transmit, and if so, after receiving all the segments of the message, synthesizing a SIP The MESSAGE message is sent to the UE in the IP network. Otherwise, the IP message gateway establishes a SIP session, uses the MSRP protocol to transmit the received segmentation message, and releases the session after all the segmentation messages have been sent.

In this case, for the format check of the message, the IP-Message-GW may not need to be executed, because the message format supported by the traditional message service is certainly supported in the IP-based message service.

After the above processing is performed on the message, the IP-Message-GW continues to execute the message receiving processing flow shown in FIG. 3, that is, continues to send a message to the user, returns a message transmission report to the SMS-GMSC, and the like.

After the foregoing processing method of the present invention is applied, the UE receiving the IP access message uses the IP-based message service to receive the message transmission process as shown in FIG. 5, and includes the following steps:

Step 51: The user registers with the IP-Message-GW.

Before receiving the message, the UE must register with the IP-Message-GW using the general registration procedure.

Step 52: The SM-SC forwards the message.

The SM-SC forwards the saved message to the SMS-GMSC.

Step 53: The SMS-GMSC queries the HSS/HLR for routing information.

After receiving the message forwarded by the SM-SC, the SMS-GMSC sends a request message to the HSS HLR to query the routing information of the message, including an indication indicating that the SMS-GMSC supports the IP message service, according to the indication, the HSS/HLR Return three E.164 addresses: MSC's SGSN, and IP-Message-GW.

Step 54: The SMS-GMSC forwards the message.

According to the obtained three addresses, the SMS-GMSC can transmit a message through any one of the addresses, where it chooses to transmit the message on the IP, so the message is in the form of standard MAP signaling. Transfer to IP-Message-GW.

Step 55: The IP-Message-GW performs length conversion processing on the message.

After receiving the message forwarded by the SMS-GMSC, the IP-Message-GW extracts the message content, and then the IP-Message-GW forwards the message to the SMS-GMSC according to the specific processing procedure shown in FIG. 4 described above. The message is length converted.

That is, if the IP-Message-GW finds that the message from the SMS-GMSC is one of the messages after the longer message is segmented, the IP-Message-GW performs multiple segment short messages according to the processing flow shown in FIG. The combination is constructed as a message transmitted using an IP-based messaging protocol.

If the IP-Message-GW finds that the message from the SMS-GMSC is a complete message, the message is not subjected to length conversion processing.

Step 56: Send a message to the user.

According to the MSISDN of the destination user, the IP address corresponding to the user is obtained from the local database, and then the length-converted message is sent to the destination UE by using an IP-based message transmission protocol.

Step 57: The IP-Message-GW returns a message transmission report.

Step 58: The SMS-GMSC sends a message delivery report status.

The SMS-GMSC sends a message delivery report status to the HSS/HLR.

Step 59: SMS-GMSC returns a message delivery report

The SMS-GMSC returns a message delivery report to the SM-SC.

Case 2. The terminal UEo uses the IP-based message service to initiate the transmission of the message, and the terminal UEt receives the message using the conventional message service.

In this case, the message transmitted by UEo first passes through the message transmission processing procedure shown in FIG. 2. After performing step 22, that is, after the IP-Message-GW receives the message sent by UEo using the IP-based message transmission protocol, the IP-Message-GW needs to perform certain processing on the received message, and the specific processing flow is as shown in the figure. As shown in 6, it includes the following steps:

Step 6-1. The IP-Message-GW receives the message. After receiving the message sent by UEo using the IP-based message transmission protocol, the IP-Message-GW extracts the content of the message, and then needs to check the content type and format of the message. If the format of the message content is checked first, then the step is performed. 6-2.

Step 6-2: Determine whether the message format is receivable by the traditional message service.

The IP-Message-GW checks the format of the message content by identifying an indication of the length and type of the message content in the IP-based message transfer protocol used by the user. If the user uses SIP MESSAGE (Session Initiation Protocol message) as the IP-based message transmission method, the format of the message content is the value of the Content-Type field in the SIP MESSAGE message.

If the message type is a format that can be supported in the traditional message service, perform the steps.

6-4; If the message type is not a format that can be supported in the traditional message service, perform step 6-3.

Step 6-3, convert the format of the message content.

If the message type is not a format that can be supported in the traditional message service, but the message format can be converted into a format that can be supported in the traditional message service, the IP-Message-GW can be based on the specific message type according to the operator's policy or other considerations. Determine if the message needs to be transmitted to UEt.

If it is decided to transmit, the IP-Message-GW converts the format of the message content into a format that can be supported by a conventional message service by removing special characters that cannot be supported on the UEt, and then performs step 6-4.

If it is decided not to transmit, the IP-Message-GW directly returns an appropriate response to the UEo, indicating that the sent message cannot be supported by the other party.

When the user uses SIP MESSAGE as the IP-based message transmission method, other message content types may be text/uri-list MIME (text/Uniform Resource Identifier -list Multipurpose Internet Mail Extension, text/general resource tag list-multiple Use Internet Mail Extensions) type, this type of identifier conveys a list of URIs (Uniform Resource Identifiers), and other formats of content types that are being defined or will appear in the future. deal with.

Step 6-4: Determine whether the length of the message is receivable by the traditional message service. After receiving the message sent by UEo using the IP-based message transmission protocol, the IP-Message-GW, after extracting the message content, checking the message content format, and performing a certain format conversion, also determines whether the length of the message is a legacy message. Business can be received. If the user uses SIP MESSAGE as the IP-based message transmission method, the length of the message content is the value of the Content-Length field in the SIP MESSAGE message.

If the length of the message content is acceptable for the traditional message service, go to step 6-6; otherwise, go to step 6-5.

Step 6-5: Segment the length of the message content.

If the length of the message content exceeds the length of the message that can be carried in each MAP signaling in the non-IP network, the IP-Message-GW segments the content of the message, and then transmits the message separately, and carries the message in each segment message. The total number of segments and the sequential position information of the current segment in the total number of segments, indicating whether there are subsequent messages in each message, and indicating that there are no subsequent messages in the last segment of the message, this process and the current GSM/GPRS network The processing of longer and shorter messages is the same. Then, go to steps 6-6.

Step 6-6: Send the message to the SMS-IWMSC;

The IP-Message-GW sends the message to the SMS-IWMSC by using standard MAP signaling. The above two processings of the length and format of the message content may also be changed to first process the length of the message content, and then the content of the message. The format is processed, that is, steps 6-4, 6-5 are performed first, and then steps 6-2, 6-3 are performed.

After the message content length and format conversion processing is performed as described above, the message transmission processing flow shown in Fig. 2 is continued. After the destination UEt receives the message transmission report, the message receiving processing flow shown in FIG. 3 is performed, and the message is sent to the destination UEt.

Of course, it is understood by those skilled in the art that when the message is converted, only the processing for the length may be performed according to the actual situation, or only the processing for the format may be performed, which is not described here.

After the foregoing processing method is applied, when the terminal UEt receives the message by using the traditional message service, the process of transmitting the message by using the IP-based message service by the UE supporting the IP access is as shown in FIG. 7, and includes the following steps:

Step 71: The user registers with the IP-Message-GW. To use short message service in a network based on IP access technology, the UE must first register with the IP-Message-GW.

Step 72: The user sends a message.

The UE sends the short message to be transmitted to the IP-Message-GW, and it is recommended to use the existing IP-based message transmission method.

Step 73: The IP-Message-GW processes the length and format of the message.

After receiving the message sent by the user, the IP-Message-GW extracts the length and format of the message content, and then the IP-Message-GW performs the length of the message according to the specific processing flow shown in FIG. 6 described above. Format conversion processing.

Step 74: The IP-Message-GW forwards the message content.

The IP-Message-GW extracts the content of the message processed by the length and format conversion, obtains the MSISDN (Mobile Station ISDN number) corresponding to the IP address of the user from the local database, and constructs a standard MAP (Mobile Application Part) signaling. The message content and the MSISDN are sent to the SMS-IWMSC; the following message procedure details using the MAP are defined in TS 23.040.

Step 75: The SMS-IWMSC forwards the message.

The SMS-IWMSC forwards the received message to the SM-SC.

Step 76: The SM-SC sends a message transmission report.

Step 77: SMS-IWMSC sends a message delivery report

After receiving the message transmission report forwarded by the SM-SC, the SMS-IWMSC sends a message transmission report to the IP-Message-GWo.

Step 78: Send a message delivery report to the user.
