Embodiment
Consult shown in Figure 1ly, signalling processing equipment possesses ISDNYong Hubufen (ISUP) or Telephone User Part (TUP) signaling protocol disposal ability, but it does not need relay resource, and cooperates the realization call handling capacity by a switch.
On switch, will carry out E1 with the relaying of the corresponding office direction of signalling processing equipment, be about to first, second two E1 interface interconnection from ring.As, 1 to No. 30 repeat circuit among first E1 of exchanger side is mapped to 33 to No. 62 repeat circuits among second E1 accordingly, even the voice that enter from cic circuit identification code (CIC)=1 will come out from CIC=33, in like manner, the repeat circuit of CIC=2 is the repeat circuit of corresponding CIC=34, other and the like.
For one from the switch to signalling processing equipment calling, voice messaging will be by the E1 passage from ring, turn back to exchanger side, do not pass through signalling processing equipment, but the ISUP signaling relevant with calling intactly passed through signalling processing equipment, signalling processing equipment is understood call information by these call signalings, and controlling call.
In communication network shown in Figure 2, switch C is connected with signalling processing equipment, realizes call handling capacity by both cooperations, and then the speech channel in the network is monitored.
Carry out relaying from ring on switch C, the side-play amount Y of cic circuit identification code (CIC) depends on two intervals of encircling the CIC between the E1 interface certainly of switch after the ring certainly, is generally 32 multiple.
For the calling of initiating from switch A, is that the call proceeding of A to switch C to the called number analysis (specific called number being routed to switch C by pre-configured) that carries out with called number by each network entity, switch C analyzing called number is that the calling of A need be routed to signalling processing equipment, and (first repeat circuit refers to a repeat circuit in this E1 interface to distribute first repeat circuit among the E1, as, the repeat circuit of CIC=0; Second repeat circuit in like manner.)。After signalling processing equipment is received initialization address message (IAM message), called number A is revised called number B, simultaneously the CIC number is increased a side-play amount Y (as, Y=32), and IAM message sent to switch C, behind the switch C analyzing called number B with call proceeding to switch b.For continue ACM, the ANM of switch b response, signalling processing equipment removes the offset Y among the CIC and returns to switch C.Final first, second repeat circuit that passes through to encircle certainly makes the speech information between calling and called not pass through signalling processing equipment caller and called connection.
Consult shown in Figure 3ly, the concrete handling process of a calling is as follows:
1, switch A is that the call proceeding of A is to switch C with called number by sending initialization address message IAM.
2, switch C analyzing called number is that the calling of A need be routed to signalling processing equipment, then sends IAM message to signalling processing equipment, and the cic circuit identification code that carries in this message is the identification code of first repeat circuit of an E1 interface, i.e. CIC=X.
3, after signalling processing equipment is received calling, called number is revised as B; Simultaneously CIC is increased a side-play amount Y (CIC=X+Y), making CIC is the CIC of second repeat circuit corresponding with first repeat circuit in the 2nd E1 interface, and by send IAM message with call proceeding to switch C.(being routed to the calling of switch C this moment, is new a calling from the signaling equipment to the called number for switch.)
Wherein side-play amount Y is come to determine by two E1 interface CIC at interval from ring at interval, as, previous examples, side-play amount are 32.
A is revised as B with called number, is in order to prevent that switch C from causing circulation with call proceeding to signalling processing equipment.
4, switch C analyzing called number B, and transmission IAM message arrives switch b with call proceeding.
5, switch b is responded Address Complete Message ACM to switch C.
6, switch C responds ACM message to signalling processing equipment, carries the CIC of second repeat circuit in this message, i.e. CIC=X+Y.
7, signalling processing equipment is responded ACM to switch C, and the CIC in this message is the CIC of first repeat circuit, i.e. CIC=X.
8, switch C responds ACM message to switch A.
9, switch b sends response message ANM to switch C.
10, switch C sends ANM to signaling equipment, and the CIC in this message is the CIC of second repeat circuit, i.e. CIC=X+Y.So far, the speech channel between second repeat circuit connection switch C and switch b.
11, signalling processing equipment sends ANM to switch C, and the CIC in this message is the CIC of first repeat circuit, i.e. CIC=X.
12, switch C sends ANM to switch A.
Arrive this, connect speech channel between switch A and the switch C through first repeat circuit and since first repeat circuit and second repeat circuit at exchange side from ring, so that the connection of the speech channel between the calling and called, its speech information does not pass through signalling processing equipment.
Handling process is as follows during Called Onhook:
A, Called Onhook, switch b sends release message (REL message) to switch C.
B, switch C send to signaling equipment and discharge REL message, carry the CIC of second repeat circuit in this message, i.e. CIC=X+Y.
C, signaling equipment send REL message to switch C, carry the CIC of first repeat circuit in this message, i.e. CIC=X.
D, switch C send REL message to switch A.
E, switch A are responded Release complete (RLC message) to switch C.
F, switch C respond RLC message to signaling equipment, carry the CIC of first repeat circuit in this message, i.e. CIC=X.
G, signaling equipment are responded RLC message to switch C, carry the CIC of second repeat circuit in this message, i.e. CIC=X+Y.
H, switch C respond RLC message to switch b.So far, connect calling and called first, repeat circuit is released.
Switch can be fixed switch in the present invention, also can be mobile switch.Can on switch, form a plurality of E1 interfaces as required from ring.
The present invention encircles certainly by the E1 interface of switch, makes signalling processing equipment under the situation that does not possess relay resource, thereby possesses the speech path control ability by handling isup message.
