Description:
TECHNICAL FIELD 
     The disclosure relates to a mobile communication technology, in particular to a system and method for implementing concentrated access of a Business Operations Support System (BOSS). 
     BACKGROUND 
     With the rapid development of mobile communication networks and the rapid increase of the user amount of mobile communications, a large-capacity and distributed Home Location Register (HLR) system in the mobile communication networks has become the development trend of the mobile communication networks in the future. 
     Since a distributed HLR system has much higher requirements on the user amount and processing capacity than a traditional HLR system, the distributed HLR system generally needs to provide a plurality of data access servers for a BOSS system to perform business acceptance; meanwhile, due to the huge user amount of the distributed HLR system, business acceptance instructions processed by the BOSS system per unit time are also obviously increased, therefore it is necessary to set a plurality of BOSS subsystems in the BOSS system; each BOSS subsystem can access a plurality of data access servers of the distributed HLR system concurrently and the capability of processing business acceptance is improved by distributing business acceptance messages by the BOSS system. 
       FIG. 1  is a schematic diagram showing the access of a BOSS system to an HLR system in the prior art, as shown in  FIG. 1 , the BOSS system and the distributed HLR system are two different networks, and the access of the BOSS system to the distributed HLR system needs a special network deployment. However, data access servers of the distributed HLR system are generally distributed at different geographical locations, while the BOSS system generally processes all the acceptance instructions of the terminals of each location centralizedly at one location, therefore, if the BOSS system accesses a plurality of data access servers, a cross-regional network deployment is required, which not only has high requirements on the network deployment, but also reduces the network security of the HLR as the distributed HLR system exposes a plurality of access points to networks besides the distributed HLR. 
     In addition, the BOSS system does not know the load condition of each component inside the distributed HLR system, therefore, the BOSS system can only adopt a simple distribution policy for the plurality of data access servers of the distributed HLR system.

     Step  301 : The BOSS sends a business acceptance request to the concentrated access interface machine. 
     Step  302 : The concentrated access interface machine parses the user identifiers in the business acceptance instruction and queries the historical distribution record. 
     Step  303 : The concentrated access interface machine selects a data access server according to a condition of the queried historical distribution record. 
     If the user identifiers do not exist in the historical distribution record, the concentrated access interface machine selects a data access server according to the current load condition of the data access server; 
     if the user identifiers exist in the historical distribution record and a data access server corresponding to the historical distribution record is normal, the concentrated access interface machine selects the data access server to process the current business acceptance instruction; and 
     if the user identifiers exist in the historical distribution record but a data access server corresponding to the historical distribution record is abnormal, the concentrated access interface machine temporarily delays processing the business acceptance message, then timely checks the state of the target data access server; if the data access server is still abnormal after 3 attempts (the times can be flexibly configured), the concentrated access interface machine deletes the historical distribution record of the user identifiers and reselects a data access server according to the current load condition of the data access server. 
     Step  304 : The concentrated access interface machine sends the business acceptance instruction to the selected data access server. 
     Step  305 : The data access server operates an HLR database according to the business acceptance instruction. 
     Step  306 : The HLR database returns an operation result to the data access server. 
     Step  307 : The data access server returns the operation result to the concentrated access interface machine, if the operation is successful, the returned result includes all the user identifiers. 
     Step  308 : The concentrated access interface machine records the user identifiers to a new historical distribution record; if the user identifiers have existed, an old historical distribution record is deleted; if the historical distribution record is full, the oldest historical distribution record is deleted, and a new historical distribution record is written. 
     Step  309 : The concentrated access interface machine returns the operation result to the BOSS.
