Described business operation support system and communicating by letter of attaching position register often are the front-end processor systems by attaching position register.Therefore, in this area, business operation support system is comprised that the attaching position register front-end processor system is referred to as Socket (socket) client.For convenience, below just replace business operation support system with the title of Socket client, the function of interface treatment system of the present invention is further described.
1, the socket link unit that described foundation is connected with business operation support system is sets up Socket (socket) connection.Because communicator of the present invention is as the Socket server.So this element at first is the access of waiting for the Socket client.Behind the connection request of receiving the Socket client, the interface treatment system is accepted the connection request of Socket, and a newly-built process handles this Socket and connect, and promptly sets up Socket (socket) and connects.
2, the Switched Virtual Circuit unit that described foundation is connected with attaching position register is foundation and X.25 connects.This communicator is at the connection request of receiving the Socket client, and after setting up Socket (socket) and connecting, the interface treatment system is initiated X.25 calling to attaching position register, and indicates and need Terminal Service (Termial Service); Attaching position register is replied calling X.25, X.25 connects link and is created as merit; After the relevant parameter of this communicator of hlr inquiry, relevant parameter is set.Attaching position register begins Terminal Service (Terminal Service) is distributed to this connection, starts the service of landing.
1, Data Receiving, processing and forwarding.The interface treatment system is done corresponding processing with the data that the Socket client in the Socket connection that receives is sent, and is forwarded in the X.25 connection, finally arrives attaching position register; The data that X.25 connect that the interface treatment system postbacks attaching position register are again done corresponding processing, and are forwarded in the Socket connection, finally arrive the Socket client.
2, disconnect connection.When receiving the disconnection connection request of Socket client, the interface treatment system disconnects and being connected of X.25 blocking, and then the communication link of the X.25 port of Socket client and attaching position register disconnects.
Described Socket is used for allowing a process and other process exchange information.And the Socket interface is the interface function of the application programming interfaces (Application Programming Interface) of TCP/IP network.Described communicator is meant and at first creates a service port number as the Socket server, and begin to intercept whether the client requests connection is arranged.The establishment of said Socket client is meant the server host name is set, as IP address, domain name or computer name, Service-Port is set then.After the establishment of Socket client and server is finished, promptly connect and finish, can begin communication.
X.25, described initiation is called out and is meant that this communicator is by request communication process calling attaching position register.The described link that X.25 connects is created as merit and is meant and can utilizes X.25 that agreement begins to carry out full duplex data communication.The relevant parameter of said communicator is meant X.25 address, domain name, port numbers, the password that lands, password etc.
Described data processing is because originally based on the execution command of the attaching position register of RS232 interface with current based on the execution command of the attaching position register of interface X.25 inconsistent part is arranged.This communicator need be done corresponding processing according to both sides' inconsistent point and be sent to separately communication objective ground again after the data of receiving business support system or attaching position register.The processing of the data of being done generally includes:
1) from the data of the attaching position register that X.25 receives, with the character string that comprises in the data " 1B[0m 1B (A " deletion, wherein " 1B " is hexadecimal value 1B, have " " expression is hexadecimal.Character string “ 1B[0m 1B (A " relevant with row control in interface X.25, do not belong to instruction execution result, therefore need deletion.
2) receive the data of operation system from Socket, if last position is not in the data that receive data " 01 " and receive previously " 1B ", then data " 1B " are put into Socket memory queue array, and be inserted in data " 01 " the memory queue array before.For example, suppose that the memory queue array sequence number that " 01 " deposits originally is 4, then after this judgement and operation are finished memory queue array sequence number to be the data deposited in 4 the array be " 1B ", memory queue array sequence number to be the data deposited in 5 the array be " 01 ".
Do this operation and mainly be because attaching position register X.25 in the interface regulation attaching position register must receive data “ 1B 01 " the back attaching position register just sends "〉" prompt, wait for interface handling procedure input command; If only receive data " 01 ", then do not do any operation.Therefore receive data “ 01 when the interface handling procedure " and data before be not “ 1B " time, need be with data “ 01 " be treated to data “ 1B 01 " just can send prompt.
3) receive the data of operation system from Socket, if receive data " 18 " and the data that receive previously in last position be not " 1B ", then data " 1B " are put into Socket memory queue array.And be inserted in data " 18 " before the memory queue array in.For example, suppose that the memory queue array sequence number that " 18 " deposits originally is 4, then after this judgement and operation are finished memory queue array sequence number to be the data deposited in 4 the array be " 1B ", memory queue array sequence number to be the data deposited in 5 the array be " 18 ".
Do this operation and mainly be because X.25 the regulation attaching position register must be after receiving data " 1B 18 " in the interface at attaching position register, attaching position register is just exported "〉〉〉1: open both sides' sessions (DIALOGUE SESSION OPENING); 2: the side's of operation conversation end (END OF OPERATORSESSION); Your selection (YOUR CHOICE)==" character string and prompt, wait for interface handling procedure input selection character " 1 " or " 2 "; If only receive data “ 18 ", then do not do any operation, therefore receive data “ 18 when the interface handling procedure " and data before be not “ 1B " time need with data “ 18 " be treated to data “ 1B 18 ".
For improving the communication speed of Socket client and attaching position register to the full extent.Data Receiving and forwarding capability in the interface treatment system of the present invention have utilized memory queue.Two memory queues in internal memory, have been distributed.In the memory queue, with the array form deposit respectively from the Socket connection with from X.25 being connected the data that receive.Promptly deposit respectively from business operation support system and the data sent from attaching position register.Corresponding each memory queue defines two variablees respectively, in order to can read the array sequence number at first and can write the array sequence number at first in the record memory field.Deposit data and the step that reads are as follows:
A. distribute two memory queues.The size of memory queue depends on the data signaling rate in the Socket connection and the instruction execution speed of data signaling rate that X.25 is connected and attaching position register.If memory queue definition is too little, from Socket connections, or will not have the space and deposit from X.25 connecting the data of receiving, can not send in time in the X.25 connection, or in the Socket connection, will cause the data obstruction.If the memory queue definition is too big, then memory queue is not effectively utilized, and has just caused the waste of memory source yet.Array quantity in the comprehensive above-mentioned reason and according to practical experience, memory queue fix on 8～20 comparatively desirable.
B. define two variablees of corresponding each memory queue respectively.Can read at first and can read the array of data sequence number at first in the array sequence number variable record memory queue, from 0 to N (N is the array quantitative value of memory queue), increase progressively successively, in the time can reading array sequence number variate-value at first and be N, will can read at first array sequence number variate-value again assignment be 0; Can write the writeable at first array sequence number in the array sequence number variable record memory queue at first, from 0 to N (N is the array quantitative value of memory queue), increase progressively successively, in the time can writing array sequence number variate-value at first and be N, will can write at first that array sequence number variate-value composes again is 0.
C. determine the state of memory queue according to the value that can read array sequence number variable at first and can write array sequence number variable at first, and whether decision receives new data and judgement and has and do not need the data transmitted.All be defined as 0 when 1) two variablees are initial; 2) equate that expression has not had to read needs the data transmitted when two variablees; Under other situations, but sense data; 3) it is full to be that the internal memory memory queue has been write in the time can reading array sequence number variable-can write array sequence number variable=1 at first at first or can read array sequence number variable-can write at first array sequence number variable=1-N at first, can not receive new data again; Under other situations, memory queue can write data.
The remarkable benefit that is used for the communicator of attaching position register (HLR) of the present invention.
Communicator of the present invention is by Ethernet (Ethernet) card, uses ICP/IP protocol to communicate by letter with business operation support system (BSS/OSS); Link to each other by X.25 blocking with attaching position register, and the X.25 standard traffic that utilizes the attaching position register interface to be supported, that is to say the transmission link between business operation support system (BSS/OSS) and attaching position register (HLR), meet the new open X.25 requirement of port communication speed of interface of attaching position register.To originally change into based on the transmission rate of the 64Kbps of communication protocol X.25 based on the transmission rate of the 9.6Kbps of RS232 communication protocol, the attaching position register front end processor (HLR FRONT SERVER) in the business operation support system does not need to revise it originally based on the command format of attaching position register RS232 interface simultaneously.
Under the attaching position register front end processor (HLR FRONTSERVER) of business operation support system (BSS/OSS) and the distance between the attaching position register (HLR) situation far away, can between this communicator and attaching position register, add router and be connected to attaching position register (HLR).As long as have the standard interface identical (as EIA530 on the router with the attaching position register interface, the communication protocol standard interface X.25 that International Telecommunications Union formulates, it adopts the balance mode transmission, contain 37 cores or 25 core connectors, meet the standard interface of the physical layer interface standard of Electronic Industries Association's exploitation) promptly passable.So communicator of the present invention can also be applied to the long situation of link.
