B. then, the socket (SOCKET) of setting up a TCP/IP between the access main frame of this ambient systems and SMP is connected;
C. after connection is set up successfully, insert main frame log on command is assembled into the service message form and sends to SMP by the SOCKET connection that step b is set up;
D. after inserting the message that main frame receives that SMP returns, judge whether to login successfully? if login successfully, then enter step e, if login is unsuccessful, then judges whether and to login again, if desired, then get back to step c, otherwise, remove to insert main frame and be connected with SOCKET between SMP and withdraw from;
E. inserting main frame is assembled into manmachine command (MML) the service message form and sends to SMP;
F. after inserting the message that main frame receives that SMP returns, return results is carried out respective handling, and judge that whether insert main frame also needs to continue to send other order, if also need to send, then gets back to step e; Otherwise, enter step g;
G. insert main frame and send and to exit command, and dismounting is connected with SOCKET between the SMP to SMP.
Identical user name and corresponding password when using in the log on command that step c sent out with step a establishment number of the account.
The described manmachine command of step e is the order that any access main frame has the right to operate.
Described service message comprise message opening flag, message-length, message header, can the thread of a conversation, affairs head, operation information, verification and and another message opening flag of the expression end of message.Wherein, message header comprises version number, terminal iidentification and Service name at least; Can comprise session id, session control word and reserve part at least by the thread of a conversation; The affairs head comprises affairs ID, affairs control word and reserve part at least; Operation information is the MML order.
This method also further comprises the steps: to insert main frame and regularly send heartbeat message to SMP when SMP is idle with the access host communication.This heartbeat message is mainly by message opening flag, message-length, filling content and verification with constitute.
Described MML order is made of command code and parameter block, separates with colon between command code and the parameter block.This command code is made up of order prefix and command body, separates with colon between order prefix and the command body, and command body is made up of maximum three identifiers, separates with the space between each identifier.
Key of the present invention just is: utilize message format that open interface sets and manmachine command to carry out communication between the access main frame of ambient systems and SMP, and, before communication, ambient systems to this access is created a number of the account on SMP earlier, and set all authorities, and between access main frame and SMP, set up a SOCKET then and connect, communicate again through after the login authentication, when they do not need to communicate by letter, remove connection.
This shows, adopt after SMP Open Interface provided by the present invention manages intelligent network, intelligent net system and operation system respectively do for oneself battalion, mutual drawback such as obstructed, the operation interface variation of data have been avoided, make the developer of operation system can develop interconnection system apace, organically combined with intelligent net system and operation system, accomplish that data interchange is got mutually, the information Real-Time Sharing, make Virtual network operator that more effective and better service can be provided, both make things convenient for operator and developer, made things convenient for vast domestic consumer again.

Embodiment
Following conjunction with figs. is further described as follows to detailed technology content of the present invention:
In order to realize of the management of external network operation system to intelligent network, realize the interconnection of various legacy networks and intelligent network, the present invention at first provides a kind of interface of opening, can support the intercommunication of arbitrary network and intelligent network by this interface, extraneous arbitrarily network system can be managed intelligent network by this open interface, the positional structure relation of this interface and SMP and extraneous network system as shown in Figure 2, this open interface is between the front end processor of SMP and ambient systems, and this interface adopts general MML order carrying out transmission communication.
The operator that ambient systems can be used as one or more different stages of SMP inserts, and the control of authority of ambient systems is finished by SMP, and when ambient systems inserted SMP as the operator, the SMP IP address of system to external world carried out authentication.And ambient systems built-in function person's number of levels and rights management are finished by ambient systems.
When SMP and the interconnection of ambient systems access server, the protocol architecture of Cai Yonging adopts the open interface agreement at the open interface layer as shown in Figure 3 therebetween, and the lower floor of open interface adopts ICP/IP protocol.
Say that further the open interface agreement is meant: ambient systems must be set up TCP/IP SOCKET with SMP and be connected before sending message with SMP, after ambient systems no longer needs to carry out alternately with SMP, must remove with the SOCKET of SMP and is connected.The service message of open interface agreement is used to transmit user's operation information, is to carry out mutual least unit between ambient systems and the SMP.The structure of this service message is as shown in Table 1:
The message opening flag Message-length Message header Can the thread of a conversation The affairs head Operation information Verification and The message opening flag
Table one open interface service message structure
Be connected when having created between ambient systems and the SMP, session and determine affairs ID after, the message format that ambient systems provides according to table one breaks into the message bag with manmachine command (MML) and issues SMP, and the message bag of also SMP that is received being sent is simultaneously decoded by this form.
Wherein, the message opening flag is used for determining the beginning and the end of message, and length is 4Byte, is encoded to " open interface ".Message-length is used to refer to the total length from the message header to the operation information, represents with 4 16 system characters.20 bytes in message header position comprise version number, terminal iidentification and Service name three partial informations, and version number is used for discerning the protocol version of open interface; Terminal iidentification is used to identify the front end processor and the terminal of the ambient systems that inserts SMP, and SMP only carries out authentication to the terminal iidentification of front end processor; Service operator by name wants requested service.
Session is that one virtual (logic) inserting between the ambient systems of SMP and the SMP is connected, and the unique identification ambient systems is once effectively logined to SMP's.18 bytes of the meeting thread of a conversation, it comprises session id, session control word and three parts of reservation, session id is to be distributed by SMP, is used for session of being initiated by ambient systems of unique identification, different sessions has different ID values and is not equal to 0.Affairs are to insert the ambient systems of SMP and the once transaction between the SMP.Affairs 18 bytes are made up of affairs ID, affairs control word and reservation, and affairs ID is distributed voluntarily by ambient systems, is used for identifying affairs, and different affairs must have different ID values and be not equal to 0 in same session.Verification and then be by 32 XORs, to the value after the XOR negate as a result to " message header+meeting thread of a conversation+affairs head+operation information ".And the content of operation information is the MML order.
The key that ambient systems manages intelligent network just is to send out MML order to SMP, and every MML of ambient systems orders to SMP, and SMP sends the MML ACK of receiveing the response in should be at a fixed time, otherwise thinks connection interruption or fault between them.
A MML order mainly is made up of command code and parameter block two parts, and it forms form as shown in Figure 4, and command code has been stipulated the function that intelligent net system should be carried out.And command code is made up of order prefix and command body, and whether the order prefix is mainly used to identify certain bar order is to respond order, if order then prefix is ACK for response, separates by colon and command body.The order prefix also can be " MON ", represents a sense command, or " NOTIFY " expression notification message.Command body comprises three identifiers at most, separates with the space between the identifier, and as shown in Figure 5, these three identifiers are represented respectively to carry out action, as ADD, DISP, MOD, CRE; Carry out the residing service of action, as PPS, WAD, SYS; And the object entity of carrying out action, as ACNT, OPER.Parameter block is the necessary information of the function of appointment in the fill order sign indicating number, and the information in the parameter block is represented by some specific parameters according to concrete order.For instance, the order of listing the pre-payment number of the account is: DISP PPS ACNT:MSISDN=" 13900001234 ".
The formation of MML order can be used letter, numeral, separating character, spcial character or its combination, and wherein, the numeral system of use can be binary system, octal system, the decimal system, hexadecimal or digit strings; Separating character can for colon, equal sign, comma; , ﹠amp; ﹠amp; , apostrophe (') or branch; Spcial character be double quotation marks, space, new line, *Symbol, # symbol, Chinese character or consecutive numbers (-).
When SMP and ambient systems communication are idle, for detect between ambient systems and the SMP be connected whether normal, need the timed sending heartbeat message, general heartbeat message is just to send after detecting continuous 120 seconds without any message and sending, if continuous can not receive heartbeat message then think to connect for three times interrupt.Its message format is as shown in Table 2:
The message opening flag Message-length Fill content Verification and
Table two heartbeat message format
In this message, message opening flag and verification and two parts and service message content are consistent, and message-length is 4, and filling content is the HBHB character string.
Intelligent network is managed is that message format and MML order by top open interface that provides and setting thereof finished in outside network operation system among the present invention, and as shown in Figure 6, its specific implementation process comprises the steps: at least
1) when the external network operation system need interconnect with intelligent network, at first is that one of the system creation of required access inserts number of the account on SMP, and sets certain authority.Wherein, creating the user has the term of validity, if before the deadline, this user can repeatedly login and need not to create new number of the account again; If surpass the term of validity, then this user account is invalid, just can not login; Login again can only be created a new access account again if desired.
2) then, the access main frame of network operation system is connected with the socket (SOCKET) that SMP sets up a TCP/IP.
3) connect set up successfully after, according to the structure of interface protocol message log on command is assembled into the service message form and issues SMP, to use identical user name and the corresponding password created with step 1) in the log on command.
4) after inserting the message that main frame receives that SMP returns, judge whether to login successfully? if login successfully, then enter step 5), if login is unsuccessful, then judges whether and need login again, if desired, then get back to step 3), otherwise, enter step 9) and withdraw from.
5) insert main frame and by the interface protocol message format MML command group is dressed up the service message form and issued SMP, this order can be any order of having the right to operate.
6) after inserting the message that main frame receives that SMP returns, return results is handled, and judged whether insert main frame also needs to continue to send other order.
7) if inserting main frame also needs to send order, then get back to step 5); Otherwise, enter step 8).
8) inserting the main frame transmission exits command to SMP.
9) insert main frame remove with SMP between SOCKET be connected.
Adopt method of the present invention, can add the management function to intelligent network in any system, and can support emerging business at any time, the intelligent network in the inventive method comprises Fixed Intelligent Network and mobile intelligent net.Open interface among the present invention at present just provides the MML command set of multiple business such as comprising prepayment service, virtual private network service, advertising business, familiarity number.
