Description

System and method for interworking of short message and instant message services based on softswitch system

technical field

The present invention relates to a system and method for intercommunication between short message service and instant message service in a switching network, in particular to a system and method for intercommunication between instant message and short message services based on a softswitch system .

Background technique

In the traditional telecommunication network of the prior art, especially in the wireless network, the short message service has been a kind of very general service, and it usually refers to between the short message user or the short message user and other external systems, such as e-mail, The business of transmitting digital information between voice mailboxes, including text, voice and images.

With the development of the network, a new service—instant messaging (instant messaging)—appears in the telecommunication network and IP network. The instant message service takes the instant message server as the main body to realize the real-time transmission of messages. Between two users who are set as friends with each other, they can see each other's status. When both parties are active, instant messages sent by one party can be transmitted to the other party's device in real time. If the other party is not active, you cannot send him an instant message. Compared with communication methods such as short messages and e-mails, instant messages are more interactive and real-time, and are more suitable for communication methods such as chatting.

With the further development of the network, the next generation network (NGN) using the softswitch system has become more and more obvious to become the current development trend. The softswitch network combines the advantages of the traditional telecommunication network and the IP network, and inherits their original For some services, the softswitch network has a very flexible organization mode, and has considerable independence and openness; of course, short message and instant message services are also two indispensable services in the softswitch network.

Since the two services have certain commonality, they can carry information based on text, voice and images in content, and both have a relatively large user base, so it is necessary to enable users of the two services to communicate with each other. In order to diversify the services provided by the system.

In U.S. Patent 20020165000 "Instant messaging to a mobile device" (instant messaging to a mobile device), a method for using instant messaging in conjunction with short messages on wireless communication devices is proposed to improve battery and channel utilization, reduce Purpose of Communication Fees.

However, in the softswitch system, the forms of terminals are more diverse, including terminals in traditional communication networks, as well as developing and future terminal equipment such as SIP terminals, not only based on wireless communication equipment, so in Saving battery energy, channel capacity and communication costs in softswitching networks is no longer the primary purpose. In the above US patent, if the short message user does not log in the instant message service or does not have an instant message service account, he cannot send messages with the instant message user. Moreover, terminals are usually optimized for different functions. Therefore, when a user holds a short message terminal, the instant message service may not be available or may be inconvenient to use; otherwise, when the user holds an instant message terminal, Short message service may also be unavailable or inconvenient to use. Therefore, it is necessary to support short message users to send short messages to instant message users through the short message service, and support instant message users to send instant messages to short message users through the instant message service.

In addition, in the softswitch system, since the softswitch device is the core control device and holds the information of short message users and instant message users, the two services can be switched conveniently.

Detailed ways

Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

Among them, what needs to be explained in advance is that the concepts of instant message terminal and user and short message terminal and user are used in the description of the present invention. Register, log in and log out of the service, just like when logging in to an instant messaging server through a computer or mobile phone, different users can use this hardware terminal to log in. The computer or mobile phone is the terminal on the hardware, and different users use the same hardware Terminals can have different account numbers and passwords. To simplify the description, this specification refers to the case where a user uses a terminal to log in. Terminal and user have the same meaning. within the protection scope of the present invention.

The system of short message and instant message service intercommunication based on softswitch system of the present invention mainly is made up of following several parts, as shown in Figure 1, a softswitch device, an instant message server, a short message center, a short message terminal and An instant messaging terminal. The softswitch is respectively connected to the short message terminal, the instant message terminal, the short message center and the instant message server. In addition to the commonly used functions and modules, the softswitch has added the access number identification function and the short message and instant message format conversion module of the short message and instant message intercommunication service, and the short message and instant message format conversion module It can also be set on the instant message server.

The short message and instant message format conversion module should be realized according to the short message and instant message standard adopted by the system. The transformation of the message usually includes the transformation of the address, the transformation of the attribute and the transformation of the content. Address conversion means that the short message system and instant message system usually use different address expressions, so the source and destination addresses of the message should be properly converted. Attribute conversion means that in short messages and instant messages, the additional attributes of messages are not exactly the same, and the relevant attributes should be converted so that they can be correctly identified and processed by the destination message system. The conversion of content means that the message content formats supported by instant message terminals and short message terminals are not necessarily the same. For example, instant message terminals usually support multimedia messages, while some short message terminals can only support text messages, while others can support multimedia message. When the content is converted, the result usually includes message content that can be converted to the message content supported by the short message terminal and message content that cannot be converted, and then further processed by related equipment.

The instant message server is connected with the soft switch device in communication. In addition to the commonly used functions and modules, the instant message server also increases the identification function of new instant message options, that is, the identification of short message identification options.

The instant message terminal is communicatively connected with the softswitch device. In addition to the commonly used functions and modules, the instant message terminal also has the function of identifying new options of instant messages, that is, the identification of short message identification options.

The short message terminal and the instant message terminal may be connected to different softswitches, and they may communicate with the softswitch through a gateway device or directly. Because it belongs to different systems, namely the short message system and the instant message system, the instant message server and the instant message terminal belong to the instant message system, and can also directly communicate with each other without passing through the softswitch for instant messaging The short message system communicates the short message to the short message terminal through the short message center and the soft switch.

After the softswitch device receives the short message sent by the short message terminal, if it is sent to the instant message user, then process it, and then send it to the instant message server of the destination through finding a path or return an error message to Short message terminal. The instant message server receives the instant message sent by the instant message terminal through the softswitch device or directly, if it is sent to the short message user, it processes it, and then sends it to the softswitch device of the destination through finding a path or returns an error message to the instant messaging terminal.

It should be noted that when the instant message terminal is started, it must first register with the softswitch device, and the softswitch device records relevant user information, and can also perform authentication and billing, and then send the registration message to the instant message terminal. The message server forwards. After the registration is successful, the instant message terminal and the instant message server can conduct instant message communication through the softswitch device or directly. When the instant message terminal terminates the service, it needs to send an exit message to the softswitch, and the softswitch modifies the corresponding state and information, and then terminates the instant message service to the user.

The following will describe the operation process of the short message and instant message format conversion module on the softswitch device, and the situation that it is set on the instant message server is similar to this.

The method for intercommunicating short message and instant message services based on the softswitch system of the present invention mainly includes two processes: the short message terminal sending a message to the instant message terminal and the instant message terminal sending a message to the short message terminal.

As shown in Fig. 2, when the user on the short message terminal needs to send a message to the user of the instant message terminal, it should first know the identity of the instant message user. The identifier of the instant message user is used in the network to uniquely identify the instant message user. At the same time, the service provider should also publish a specific access code for interworking services. Therefore, the message sent by the short message user to the instant message user should include the following content: a specific access code; and the identification of the instant message user. The short message terminal sends a short message destined for a specific access code to the softswitch, and the short message includes the identifier of the instant message user.

After the softswitch device receives the short message destined for a specific access code, it extracts the identifier of the instant message user, and queries the relevant information of the instant message user locally or on other softswitch devices. If the message cannot be forwarded to the instant message user, for example, the instant message user does not exist, the instant message user is not online, or the short message user is on the blacklist of the instant message user, then the corresponding message is returned to the short message user. Error information, and take corresponding protective measures, such as saving the message for a period of time when the instant message user is offline, and sending it after the instant message user is online.

If the message can be forwarded, then call the short message and instant message format conversion module to convert the message format, and the converted instant message should contain the following content: instant message user identification; short message user identification, converted short message content. Then the softswitch device sends the converted instant message to the instant message server, and then the instant message server sends the converted instant message to the corresponding instant message terminal.

As shown in Figure 3, when an instant message user needs to send information to a short message user, it should first know the identification of the short message user, and then send an instant message comprising the following content to the instant message server: the short message user identification option.

After the instant message server receives the instant message with the short message user identification option, it forwards it to the soft switch device for processing.

The softswitch device extracts the ID of the short message user, and queries the relevant information of the corresponding short message user on the local or other softswitch device. If the message cannot be sent to the short message user, such as the short message user is out of service, the instant message user is on the blacklist of the short message user, or the short message after conversion cannot be supported by the short message terminal of the destination, then to This instant message user returns error information, and take corresponding protective measures, for example, when the short message after the conversion can not be supported by the short message terminal of the destination, it is saved on a website that can browse this short message, and Send information such as website address and identity authentication to the short message user.

If can forward this instant message, then call described short message and instant message format conversion module to carry out format conversion, the short message after conversion should contain following content: short message user identification, instant message user identification, instant message content after conversion, and some instant message content that cannot be converted. Then the softswitch device sends the converted message to the short message center, and the short message center sends it to the corresponding short message user according to a normal process.

It should be understood that the above technical solution of the present invention is not limited to the description of the above specific embodiments for those skilled in the art, and the scope of patent protection of the present invention should be determined by the appended claims.
