Embodiment
In the networking of reality is used, on the same set of equipment together with the time operation DPNSS 1 and DASS 2 agreements, and need to carry by identical DUA agreement, it is first-class to be carried on the SG equipment DUA agreement identical with the MGC equipment room simultaneously as DPNSS 1 and DASS 2 agreements.If on same set of DUA agreement and identical E1 or T1 line, can carry DPNSS 1 agreement and DASS 2 agreements simultaneously, and the message that receiving terminal can be distinguished its reception accurately is message, or the message of DASS 2 agreements of DPNSS 1 agreement, receiving terminal just can carry out the processing of respective protocol to its message from the different signaling protocols of same interface reception, thereby can effectively save the interface resource of the network equipment, reduce the system group network cost.
Therefore, core of the present invention is: different signaling system agreements corresponding protocols identification information respectively is set, message and this message corresponding protocols identification information that transmitting terminal will need to transmit transfer to receiving terminal, and described receiving terminal is determined the signaling system agreement of the message correspondence of its reception according to the protocol-identifier information of its reception.
Based on core concept of the present invention technical scheme provided by the invention is further described below.
When DUA need be between transmitting terminal and receiving terminal message by same interface resource transparent transmission DPNSS 1 and DASS 2 agreements, as when the message of the same interface resource transparent transmission DPNSS 1 of SG and MGC equipment room and DASS 2 agreements, the message that receiving terminal DUA protocol entity need be discerned its current reception is the message of DPNSS 1 agreement or the message of DASS 2 agreements, and behind the signaling protocol of determining message, need that this message is sent to corresponding signaling protocol and handle.
Because DUA agreement not corresponding " protocol-identifier position " itself, if it is the message of DPNSS 1 agreement or the message of DASS 2 agreements from the message that same interface resource receives that receiving terminal need identify it, transmitting terminal just need transfer to receiving terminal with the message corresponding protocols identification information of its transmission.
The method of transmitting terminal host-host protocol identification information is very flexible, as adopting the method that message and this message corresponding protocols identification information are transmitted respectively, also can adopt the method that message and this message corresponding protocols identification information are transmitted together, be about to the protocol-identifier information-bearing transfers to receiving terminal in the message of needs transmission method.
Be transmitted as example together with protocol-identifier information and message below, two kinds of concrete implementation methods provided by the invention are elaborated.
Method one: the message that receiving terminal utilizes interface identifier to distinguish its reception is the message of DPNSS 1 agreement or the message of DASS 2 agreements.Its specific implementation method is:
At first, the corresponding relation of interface, interface identifier and DPNSS 1 agreement, DASS2 agreement need be set at receiving terminal and transmitting terminal, the interface here comprises: E1 interface and T1 interface.The corresponding relation of interface identifier and DPNSS 1 protocol-identifier information and DASS 2 protocol-identifier information be can't help the DUA agreement and is preserved, and its corresponding relation need be kept in the concrete application.
Because the protocol message that the present invention need distinguish is: therefore the message of the message of DPNSS 1 agreement, DASS 2 agreements, can be provided with corresponding two interface identifier of an interface, the corresponding a kind of signaling system agreement of interface identifier." interface identifier " is DUA agreement itself setting, originally be used to discern different E1/T1 circuits, the present invention gives interface identifier a new implication again, be that the present invention is identical different " interface identifier " of E1/T1 line interface definition, each interface identifier is corresponding DPNSS 1 agreement and DASS 2 agreements respectively.
As in accompanying drawing 2, corresponding DPNSS 1 agreement of definition " interface identifier " m, corresponding DASS 2 agreements of n, but the m E1/T1 Interface all corresponding identical with n.Like this, when the DUA protocol entity is received the message that different " interface identifier " report, can discern the current message that reports according to interface identifier is that the message of DPNSS 1 agreement still is the message of DASS 2 agreements, when receiving the message that " interface identifier " m reports when the DUA protocol entity, it is DPNSS 1 message that the DUA protocol entity can be discerned this message, and this information reporting to DPNSS 1 agreement is handled accordingly; When the DUA protocol entity was received the message that " interface identifier " n reports, it was DASS 2 message that the DUA protocol entity can be discerned this message, and this information reporting to DASS 2 agreements are handled accordingly.
Method one needs terminal device such as the SG and the corresponding relation of the good interface identifier of MGC equipment as offered with different signaling protocols of receiving terminal and transmitting terminal butt joint, and the equipment of receiving terminal and transmitting terminal needs to preserve simultaneously the corresponding relation of " interface identifier " and DPNSS 1 agreement, DASS 2 agreements.If an end equipment is realized not according to the method, may bring problem to butt joint.
Method two: the DUA agreement increases protocol-identifier information in the DUA common message header, and the message that receiving terminal utilizes this protocol-identifier information to discern its reception is the message of DPNSS 1 agreement or the message of DASS 2 agreements.Its specific implementation method is:
Increase " protocol-identifier information " position in the DUA agreement, the message that this protocol-identifier information bit is used to discern current transmission of DUA agreement or reception is that the message of DPNSS 1 agreement still is the message of DASS 2 agreements." protocol-identifier " position in the DUA agreement can utilize original correlation reserved position or spare bits in the DUA common message header.
The common message header of DUA as shown in Figure 3, wherein, the organization definition of DLCI field as shown in Figure 4, as can be seen from Figure 4, preceding 7 bits of the 0th byte are for keeping the position in the DLCI field.These keep any one or more " protocol-identifier information " positions that all can be used as in the position.
As set when the 0th bit is for " 0 " in the DLCI field, what identify current carrying is the message of DPNSS 1 agreement, when the 0th bit is " 1 " in the DLCI field, what identify current carrying is the message of DASS 2 agreements, so, when the DUA protocol entity is received the message that same interface reports, can be that the message of DPNSS 1 agreement still is the message of DASS 2 agreements according to the current message that reports of the 0th bit identification in the DLCI field, promptly when the DUA protocol entity receives that the 0th bit is the message of " 0 " in the DLCI field, it is DPNSS 1 message that the DUA protocol entity can be discerned this message, and this information reporting to DPNSS 1 agreement is handled accordingly; When the DUA protocol entity received that the 0th bit is the message of " 1 " in the DLCI field, it was DASS 2 message that the DUA protocol entity can be discerned this message, and this information reporting to DASS 2 agreements are handled accordingly.This example is described the 0th bit as protocol-identifier information, other one or more reservations position is realized that as protocol-identifier information the method for transmission of messages and foregoing description are basic identical, is not described in detail at this.
Receiving terminal among the present invention and transmitting terminal can be the DPNSS 1L3 protocol entity of the DPNSS 1L2 protocol entity of SGW side or DASS 2L2 protocol entity or Media Gateway Controller side or DASS 2L3 protocol entity.
