Description
Technical field
The present invention relates to method for routing and system thereof in the mobile communication system, particularly in the mobile communication system, the optimization method and the system thereof of mobile toll tandem office route analysis data.
Background technology
Since the eighties, analog mobile communication system was born, mobile communication obtained develop rapidly in the whole world in the short more than ten years, develops into second generation digital system from first generation analogue system.At present, second generation digital system mainly comprises global system for mobile communications (Global System for mobileCommunication, be called for short " GSM ") and code division multiple access (Code Division Multiple Access, be called for short " CDMA ") etc., GSM being most widely used in the world wherein, the user reaches more than 100,000,000.
The maximum difference that mobile communication is communicated by letter with fixed line is that the user is in mobile status, just mean that also the coverage rate of mobile communications network must satisfy user's mobility, therefore, with GSM is example, the starting point the earliest that the GSM net is built is the covering of setting up network, and this also is the rule of all mobile communication operators person networking.The covering of network is expanded to small and medium-sized cities from the big city, expands to the suburb from down town commerce, the intensive area of user, concerning the network operator, also has a national covering problem simultaneously, is exactly the national automatic roaming that GSM realizes.
Realize whole nation roaming, must organize huge communication network.Through after the national mobile radio communication capacity-expansion project, Beijing, Tianjin, Liaoning, Shanghai, Jiangsu, Zhejiang, Fujian, Guangdong, nine provinces and cities in Heilungkiang will be provided with a pair of independently one-level junction center (TMSC1), the inter-provincial call business of provinces and cities that tandem is had jurisdiction over respectively; Hebei, Shandong, Henan, Hubei, Hunan, Shaanxi, Sichuan, Shanxi, Jilin, Anhui, Jiangxi, Guangxi, Hainan, Chongqing, 15 provinces in Yunnan will be provided with a pair of one-level secondary junction center (TMSC2) of holding concurrently, provinces and cities that tandem is had jurisdiction over inside the province, inter-provincial call business; And Inner Mongol, Guizhou, Tibet, Gansu, Qinghai, Ningxia, 7 provinces and regions, Xinjiang are not provided with independently one-level junction center (TMSC1), and its inter-provincial trunk call is by a pair of one-level junction center (TMSC1) tandem of affiliated former Regional Center.Form mesh network between the one-level junction center (TMSC1).Network configuration still is a tertiary structure, promptly is made of the three-decker of network one-level junction center (TMSC1), secondary junction center (TMSC2) and mobile end office (EO) (Mobile SwitchCenter is called for short " MSC ").One-level junction center (TMSC1) mainly is responsible for the inter-provincial long-distance service of each MSC of the mediation provinces and cities that have jurisdiction over, and secondary junction center (TMSC2) mainly is responsible for the mediation long-distance service between each MSC inside the province, and MSC mainly is responsible for local service.
Make a general survey of the evolution of mobile communications network in the world, be not difficult to find out that network always develops towards the trend of " progression minimizing, clear, the node capacity increase of aspect ".After mobile communications network develops into certain scale, MSC between the different inside the province mobile local nets offers increasing through circuit because of the increase of traffic demand, " telephone traffic transfer inside the province " function of secondary junction center (TMSC2) will progressively slacken like this, and this is the inevitable outcome of network development, evolution.Therefore the GSM net also can develop towards the trend of two-stage net, and promptly network layer is divided into: local network and Tandem network.
In Tandem network, mobile toll tandem center (TMSC) is in the hinge of traffic mediation, needs sensible office direction numerous.So in the prior art, TMSC has disposed a large amount of number analysis data, be used for route and handle.In China, maximum mobile operator has disposed more than 1,000 mobile switch in mobile radio communication; The administrative division in the whole nation has surpassed 300, and TMSC needs to dispose the nearly number analysis data more than 2,000 for this reason.These data major parts are not to be with the roaming number of administrative area code to analyze data.
The requirement of higher number analysis disposal ability on the one hand switch has been proposed in this case; Also brought very large engineering co-ordination amount on the other hand.For example, when existing network increases a MSC newly,, need all TMSC in the whole nation all will increase new roaming number and analyze data, need the TMSC in the whole nation to do Synchronous Processing for this reason in order to guarantee intercommunication.In case certain TMSC does not increase data, will cause some areas user can't with nonlocal proper communication.
In actual applications, there is following problem in such scheme: need dispose the nearly number analysis data more than 2,000 for each TMSC, the configuration effort amount is huge; When increasing MSC newly, need the TMCS of the whole network to revise data synchronously, nontechnical organization work amount is huge.
Cause the main cause of this situation to be, each TMSC relies on the number analysis data that self dispose and carries out Route Selection.
Summary of the invention

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The present invention has utilized the correlation between roaming number prefix and the division of administrative area area code, in Tandem network, set up nationwide service control point a 30 (Service Control Point, be called for short " SCP ") to store the national mobile switch roaming number prefix and the correspondence table of administrative area area code, and then carry out Route Selection by SCP30, realize connecting.Wherein, what write down in SCP30 is the corresponding relation of roaming number prefix and administrative area area code, roaming number prefix 1390010 to 1390019 corresponding row administrative division area codes 010 for example, roaming number prefix 1390020 to 1390029 corresponding row administrative division area codes 020 etc.What deserves to be explained is, if operator does not set up independently TMSC at somewhere A, and the TMSC of territory of use B, then the roaming number prefix of regional A is corresponding with the administrative area area code of regional B in SCP30.For example suppose that operator is not provided with TMSC in Shandong, Shandong and Shanghai are shared TMSC, and then if it is 13900541 that the roaming number prefix of end office (EO) is moved in Shandong, at this moment, the administrative area code of its correspondence is 021, rather than 0531.
Below in conjunction with a preferred embodiment of the present invention the present invention is described.
Be the flow process of TMSC route analysis data as shown in Figure 1.
At first, in step 100, MSC10 sends to TMSC20 and comprises the Mobile Station Roaming Number initial address message that has additional information (IAI) of (mobile station roaming number is called for short " MSRN ").IAI is first message of call.When the mobile subscriber will use MSRN when called.In the IAI message that MSC10 sends, callee's number is a MSRN, and the MSRN of national roaming subscriber is 11 national significant numbers.This step is used to illustrate that call flow is routed to TMSC20.
After call business inserts TMSC20, enter step 110, promptly TMSC20 sends Internetwork Datagram protocol (Internetwork Datagram Protocol is called for short " IDP ") message to SCP30, carries out intelligent trigger.TMSC20 carries out the IN service trigger flow by prefix " 13 ".
SCP30 enters step 120 after receiving IDP message, promptly inquires about the roaming number prefix table, according to the roaming number prefix, find out corresponding administrative area code, SCP30 is inserted into the called number front to administrative area code then, the number of changing operation issues Connect (connection) order to TMSC20 at last.For example SCP30 receives that the roaming number prefix is 1390010 IDP message, SCP30 will be according to the correspondence table of roaming number prefix and administrative area area code, find corresponding administrative area area code 021, change 0211390010 into 1390010 then, send out Connect at last and order TMSC20.
Then enter step 130, SCP30 issues Continue (continuation) order to TMSC20, and called number is reanalysed in indication, continues to call out;
Be step 140 at last, TMSC20 sends IAI message, replay call according to the administrative area area code before the roaming number to other TMSC40 after receiving the Continue order.At this moment, IAI message comprises administrative area code and MSRN.
This shows that operator can increase mobile switch, but country can not change the administrative area easily according to the needs of market development.So the enforcement of such scheme do not need can accomplish switch change data.For the mobile communication carrier that is developing rapidly, such scheme has the good technical effect: for example operator need increase a tandem switch newly.Traditional mode is to need all tandem switch all to need to adjust on a large scale data; After adopting the present invention, only need revise " roaming number and administrative area code " correspondence table and get final product according to adjusting requirement in SCP30.
Further specify the application of the present invention in the TMSC system below in conjunction with accompanying drawing 2.
As shown in Figure 2, system by SCP30, visit (the Visit Mobile Switch Center of mobile end office (EO), be called for short " VMSC ") 50 and 51, mobile toll tandem center server (TMSC SERVER) 60 and 61, media gateway (Media Gateway, be called for short " MGW ") 70 and 71 compositions, arrow connects the road and represents signaling channel, and solid line connects the road and represents the speech channel path.Wherein, VMSC50 and VMSC51 be used to handle local service with the business that is connected of TMSC20 or other TMSC40, the technical staff who is familiar with field of the present invention will appreciate that VMSC is meant the MSC at the current place of mobile subscriber; The service that provides to TMSC20 or other TMSC40 is provided for TMSC server 60 and TMSC server 61; MGW70 and MGW71 are used to finish the translation function of access, transmission and various Media Streams.
As a preferred embodiment of the present invention, the dynamic process of existing further analytical system.Suppose that the mobile subscriber A in Beijing need call out the mobile subscriber B in Shanghai.The VMSC50 at mobile subscriber A place sends to TMSC server 60 by signaling network that to comprise MSRN be 1390021123 IAI message.After TMSC server 60 is received related news, send IDP message, to the SCP30 trigger intelligent business.SCP30 is according to roaming number prefix and administrative area area code correspondence table inquiry associated row administrative division area code and the number of changing operation then, makes new called number become 0211390021123 and return TMSC server 60 by the Connect order.Then SCP30 sends the Continue order to TMSC server 60 again, and indication is reanalysed called number and continued and connects.By the analysis to the administrative area area code, TMSC server 60 is sent to the TMSC server 61 in Shanghai, destination with related news, sets up signaling with the VMSC51 at mobile subscriber B place then and is connected.After signaling connected foundation, VMSC50 can set up corresponding speech channel by MGW70 and MGW71 with VMSC51 and be connected.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
