Embodiment Construction

[0045] The present invention realizes a memory table planning and organization for fuzzy query in the HSS system, mainly including the following technical points:

[0046] (1) Store ordinary records without wildcards in a memory table, and build indexes according to actual needs.

[0047] (2) Wildcard records with wildcards are stored in another memory table.

[0048](3) There is an internal relationship between the memory table storing wildcard records and the memory table storing ordinary records, and the application layer only has direct operation authority to the memory table storing ordinary records.

[0049] (4) The wild card record storage memory table has two T tree indexes; A T tree index is sorted according to the order from left to right, and the present invention is referred to as T tree index A; Sorting is performed in the order to the left, which is called T-tree index B in the present invention; all records in the wildcard record memory table are unique records...

Abstract

The invention discloses a fuzzy searching method based on a memory bank, wherein a method of fuzzy searching is introduced, and a record is respectively stored in a common record storing table and a wildcard record storing table arranged with two T-tree indexes. For searching request of an application layer, search is performed in the common record storing table; for the record which is not found, search is performed again in the wildcard record storing table. According to the invention, under the condition that only a little memory is added, namely only a space occupied by two T-tree indexes is added, the problems of low fuzzy searching efficiency in the HSS system is effectively solved, service quality of HSS is increased. In addition, a general interface is adopted for searching, workload of code development and maintenance is reduced.

Description

technical field [0001] The invention relates to a fuzzy query method based on a memory bank, in particular to a method capable of performing fuzzy query in an HLR network element. Background technique [0002] In the network element of mobile communication, the home subscription server (HSS) service system in the HLR network element supports a single / batch query for a certain user identity, including PVI (IMPI) (Private user identities-PVI) and PUI (IMPU) (Public useridentities—PUI) query. Among them, most of the user IDs of IMS (IP Mutimedia Subsystem) are in URL format, and it is necessary to quickly find wildcard records in the memory database through fuzzy query. The single / batch query of the service profile in HSS is also to find wildcard records in the memory library through fuzzy query. The fuzzy query technology based on the memory bank has been / is being applied more and more widely in the field of mobile communication in the future. [0003] When the HSS business...
