Embodiment
Maintenance management for convenience, we have introduced basic concepts on the M3UA basis: comprise M3UA link, M3UA link set, M3UA route and M3UA entity.Between SGP-ASP (signaling gateway process-application server process) and IPSP-IPSP (Internet Protocol signaling point), connect the relation of setting up by SCTP (SCTP) and be called the M3UA link; Between SG (SGW) and MGC (Media Gateway Controller), perhaps between MGC and the MGC (end-to-end), for all links of same application server (AS) service are regarded the M3UA link set as; The logical block of finishing specific function is called the M3UA entity, as handle the logical block-application server AS of specific transactions, perhaps only finish the logical block-SGW SG of particular message forwarding capability, the M3UA entity divides for again by local terminal to be finished the logical block-local entity of specific function and is finished the logical block-destination entity of specific function by destination; Will from source M3UA entity arrive purpose M3UA entity the path of process be called a M3UA route.
In the present invention, we also further are divided into the M3UA link M3UA physical link and M3UA logical links, and have proposed a kind of perfect M3UA full distributed type management implementation on this basis.
Description about M3UA full distributed type management implementation of the present invention all is on the basis to M3UA link, M3UA link set, M3UA route and the definition of M3UA entity basic conception.
Referring to Fig. 2, share in order to realize M3UA distributed state management and the resource overall situation, be that the M3UA link further is divided into M3UA physical link and M3UA logical links with the resource of every Business Processing board management of M3UA.The M3UA physical link of service processing board No. 1 is respectively 0,1,2 among Fig. 2, and the M3UA physical link of service processing board No. 2 is respectively 0,1,2, and the M3UA physical link of service processing board No. 3 is respectively 0,1,2,3; The M3UA logical links of service processing board 1, service processing board 2, service processing board No. 3 is respectively (0,1,2) (3,4,5) and (6,7,8,9).
The M3UA physical link number is a M3UA physical link number of at each Business Processing intralamellar part its M3UA link of managing being unified to number formation, be link No. in the service processing board plate, the user can set the maximum M3UA physical link number that every service processing board can be managed.
The M3UA logical links number is to be benchmark with the service processing board, and the M3UA link that is distributed on the different business disposable plates is carried out the unified numbering of the overall situation, thus the M3UA logical links that forms number.
Therefore, all have two numberings for each bar M3UA link: the M3UA physical link number is that link number and M3UA logical links number are link number between plate in the plate.The concrete corresponding relation of the physical link of M3UA shown in Fig. 2 and M3UA logical links: the corresponding unique M3UA logical links of M3UA physical link: M3UA logical links number is number to be that link No. determines jointly in the service processing board plate by service processing board number and M3UA physical link.The M3UA logical links carries out the unified numbering of the overall situation between different service processing boards, externally embody unified state, and therefore, the M3UA logical link state on the different business disposable plates must be consistent.Simultaneously, each piece service processing board can be included the M3UA physical link of other Business Processing board managements in the compass of competency of this service processing board, promptly regards a M3UA logical links on this service processing board as.Therefore when distribution signaling traffic data-message, just can be according to the current M3UA logical link state of safeguarding on the service processing board, select an available M3UA logical links, number again this data-message is forwarded to the corresponding service disposable plates according to this logical links corresponding service disposable plates and handles, reach the purpose that the management resource overall situation is shared with this.
Referring to Fig. 3, an idiographic flow of the full distributed type management of M3UA shown in the figure.
Step 321,322 is carried out normal process when receiving the data-message of being transmitted by other veneers from core bus;
Step 331,322,323 when the state of receiving other veneers from core bus changes broadcast (step 331), is carried out normal state and is upgraded processing (step 322), and sends broadcasting response message (step 323) by core bus.
In the above-mentioned steps 302, the priority routing of selecting by the user earlier, the logical links that preferential selection has highest level; In one group of identical link of priority, to select according to the M3UA link selection mask calculating of SLS and user's selection, its calculation procedure comprises:
The M3UA link selection mask that link selection mask (SLS) in the Signaling System Number 7 message that receives and user are set do contraposition " with " logical operation, thereby skip " 0 " in two masks;
Will " with " " 1 " order among the logical operation result moves on to low level and to its high-order zero padding, write as hexadecimal number;
Above-mentioned hexadecimal number is got surplus (%) operation to number of links available in the M3UA link, and the result who gets after the surplus operation is chosen as the M3UA logical links.
Referring to Fig. 4, be 1101 as the M3UA link selection mask (SLS) that provides in the signaling message, the M3UA link selection mask that the user sets is 0101, its computational process is: to 1101 and 0101 do contraposition " with " logical operation, promptly 0 in the mask all skipped; After being time low level, the right deputy " 1 " is " 11 " with getting for lowest order through getting the right primary " 1 "; To being 0011 after its high-order zero padding, being write as hexadecimal is 0 * 3 again; In 0 * 3 pair of condition of above-mentioned hexadecimal number in the M3UA link set available link number 4 get surplus (%) operation after still be 0 * 3, so select the 3rd M3UA link (if the hexadecimal number after calculating is 0 * 6, to 4 results that get after the surplus operation is 2, then selects the 2nd M3UA logical links).
With Fig. 2 is the example explanation, suppose that three M3UA physical links on the service processing board 2 break down, can not be used for transport service, be that M3UA logical links 3,4,5 is unavailable, the M3UA logical link state ( logical links 3,4,5) that service processing board 2 can be safeguarded this plate after the state variation is carried out logical link state broadcasting to service processing board 1 and service processing board 3, prevents that other signaling messages from sending through the M3UA physical link on this plate again.Simultaneously, for Signaling System Number 7 message from high level, other available M3UA logical links that service processing board 2 can select it to safeguard send, as M3UA logical links 6,7 or 8, service processing board 2 can will be handled (service processing board 3) from the Signaling System Number 7 forwards of high level according to this logical links corresponding service disposable plates number (logical links 6,7 or 8 corresponding service disposable plates number be 3) on the corresponding service disposable plates.
In order to guarantee the crash consistency of M3UA logical link state between plate, M3UA routing state, except adopting immediately the transmit status broadcast, system adopts following method simultaneously:
1. system's fixed time broadcast: system cycle ground sends M3UA logical link state broadcast to other service processing boards, no matter whether the M3UA Link State on this plate changes, can prevent that the Link State that some X factors cause is inconsistent, fixed time broadcast does not need the other side to reply.
2. abnormal state error correction: when this service processing board M3UA Link State undesired, but receive when other service processing board is transmitted next data-message, broadcast current Link State by core bus to other related service disposable plates immediately, the M3UA link of being responsible for safeguarding as this service processing board has fault, but receive the data-message of the need of other service processing board forwarding through this faulty link, then broadcast this faulty link state immediately.
3. every service processing board need be made regular check on the current single board state of other service processing boards, also need the single board state after this plate reports variation immediately when other single board states change, M3UA adjusts accordingly M3UA Link State and routing state according to the single board state of current business disposable plates.
4. when a service processing board receives route messages, broadcast this route messages to other all service processing boards, route messages comprises: TFP, TFA, TFC etc.When sending route messages such as TFP, TFA, TFC to other office at needs, send these message by the business board of current available minimal service plate number.
