Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Ring Back Tone service is as mobile communication new business; compare with the switch system of conventional telecommunications level; the less stable of color ring systems platform; for promoting Ring Back Tone service service quality and customer satisfaction; reduction is because of the influence of CRBT equipment fault to business; fully take into account simultaneously the protection of equipment investment again, the present invention proposes the ringing 1+N disaster-tolerant scheme that makes full use of the existing network resource.
1) general thought:
After six phase of China Mobile's Jiangsu color ring systems, capacity expansion project was finished, the Jiangsu color ring systems was called out node device by 1 cover CRBT management node device and 11 covers and is formed.The general thought of the ringing 1+N disaster-tolerant scheme that the present invention proposes is: when local arbitrary CRBT calling node breaks down, by the traffic round about manner, the fault CRBT is called out traffic on the node, by the load sharing ratio rationally is set, 10 CRBT that are diverted to other normal operation are called out on the node.
2) implementation:
When A calls out the direct junction of node or signaling blocking-up to the fault CRBT:
CRBT call out the MSC of service area that node is had jurisdiction over and gateway exchange by set in advance to the alternate routing that belongs to TMSC2, when arbitrary CRBT calling node breaks down inside the province, but calling out node traffic auto switching to the fault CRBT will arrive on the alternate routing, by TMSC2 inside the province, the fault CRBT is called out the traffic that node carried to be delivered in a pair of professional tandem exchange in Nanjing (Nanjing B1/B2), Nanjing B1/B2 and all CRBT are called out node and have all been begun through circuit, rationally be provided with by data, the fault CRBT can be called out the traffic of node and evenly share on the CRBT calling node of other 10 operate as normal.
The B CRBT is called out node backstage fault, calls out the direct junction of node or signaling when not blocking to the fault CRBT:
CRBT call out the MSC of service area that node is had jurisdiction over and gateway exchange by set in advance to the alternate routing that belongs to TMSC2, calling out node when the fault CRBT only is the backstage fault, extremely the MSC of the service area of having jurisdiction over, the relaying and the signaling of gateway exchange are not blocked, then, the fault CRBT is called out the node traffic switch on the alternate routing by the mode of artificial mandatory modification route or trunk group state.
3) scheme is prepared measuring and calculating:
A emergency route aspect:
By various places end office (EO), gateway exchange to ownership TMSC2 route as alternate routing, make full use of present various places end office (EO), gateway exchange trunk group redundancy to ownership TMSC2.
By two couples of TMSC2 the fault CRBT is called out the traffic that node carried and deliver to Nanjing B1/B2, this mode has significantly reduced taking of standby relaying.Though when CRBT is called out node failure, increased traffic load between Nanjing B3/B4 and Wuxi B3/B4, but consider 512 relayings are arranged between Nanjing B3/B4 and Wuxi B3/B4, press 1 CRBT of existing network and call out the maximum traffic load accounting of node, every specific electric load only increases less than 0.1erl, and only emergent use under failure condition, should can bear fully.
Nanjing B1/B2 calls out node to all CRBT and all offered direct junction under CRBT intelligent network implementation, and this part relaying need not to use under CRBT target network mode.This part relaying can use as emergency route.
The B traffic load is rationally shared the aspect:
Because but the various places CRBT is called out the capacity resource inequality of system's disaster tolerance of node, and be subjected to the switch office data that restriction (1 prefix only can load sharing to 4 trunk group on) is set, for making full use of the power system capacity resource of CRBT node, satisfy traffic is shared all CRBT calling node demands, take into full account each various places CRBT simultaneously again and call out node processing ability; At Nanjing B1/B2 CRBT is inserted prefix 17244 and be subdivided into 17244+134,17244+135,17244+136,17244+137,17244+138,17244+139,17244+158,17244+159.Each prefix is respectively called out node in conjunction with number allocation table and CRBT inside the province can increase the allotment that load proportion carries out the load sharing ratio.By sharing the ratio allotment, realize fault CRBT node traffic is shared on each node by the load proportion that other CRBT nodes can be born.
4) scheme implementation condition:
A CRBT call platform inside the province need support to play the whole province's section CRBT sound function.
B traffic super when busy (for example mid-autumn, the Spring Festival) need careful use.
As shown in Figure 1, be ringing 1+N disaster-tolerant implementation method frame diagram in the embodiment of the invention.When a certain CRBT is called out node failure, by end office (EO) in the linchpin service area and gateway exchange alternate routing is set, Ring Back Tone service is travelled back across traffic tandem exchange (TMSC2) inside the province, deliver to the Nanjing B1/B2 of professional tandem exchange by traffic tandem exchange inside the province, basis is called out the traffic bearing capacity of node with each CRBT on the B1/B2 of Nanjing, the direct junction of opening is counted COMPREHENSIVE CALCULATING, rational load sharing ratio is set, the CRBT traffic is shared the CRBT of other 10 operate as normal and called out on the node.
