Data element information management in a network environment
View Patent ↗The present invention proposes a method for data element information management in a network environment, the network environment comprising a plurality of data element information entities ( 5 a, 5 b, 5 c, 5 d ), each keeping a respective record of data element information for a plurality of subscribers, and a request routing entity ( 3 ), adapted to route ( 4 , S 2 ) requests to a selected one of said plurality of database entities, the method comprising the steps of transmitting (S 1 ) a data element information update for a specific subscriber to said routing entity ( 3 ), selecting, at said request routing entity ( 3 ), one ( 5 b ) of said plurality of database entities for said specific subscriber, forwarding (S 2 ) said data element information update to said selected database entity ( 5 b ), and relaying (S 5 ) said data element information update from said selected database entity ( 5 a ) to another database entity ( 5 d ) of said plurality of database entities. Also, the present invention concerns a request routing entity and a database entity, adapted to mutually cooperate with each other in order to perform the method according to the present invention.
1. A method, comprising:
receiving, at a server of a network environment, a data element information update for a specific data element, said server comprising a table defining an allocation of at least three of a plurality of database entities to said specific data element, each of said plurality of database entities configured to keep data element information for a plurality of data elements, wherein a respective different priority is assigned to each allocated database entity;
selecting, at said server, one of said at least three database entities for said specific data element based on the assigned priority;
said server determining, using at least the table, information for relaying the data element information update to at least a second, next highest priority database entity of said at least three database entities and a third database entity of lower priority than said second database entity, said third database entity of said at least three database entities;
said server forwarding said data element information update and said determined information to said selected database entity;
said selected database entity, using at least said determined information, forwarding said data element information update and providing at least a portion of said determined information to said second, next highest priority database entity; and
said second, next highest priority database entity, using at least said portion of said determined information, forwarding said data element information update to a third database entity of lower priority than said second database entity.
2. The method according to claim 1 , wherein said data element information comprises information related to a subscriber of a communication network.
3. The method according to claim 1 , further comprising
acknowledging the data element information update by said selected database entity to said server,
wherein in case the selected database entity does not acknowledge the data element information update, the priorities assigned to said database entities in said table at the server are changed.
4. A system, comprising:
a plurality of database entities, each of said plurality of database entities configured to keep data element information for a plurality of data elements, wherein a respective different priority is assigned to each allocated database entity; and
a server configured to receive a data element information update for a specific data element, said server comprising a table defining an allocation of at least three of said plurality of database entities to said specific data element, wherein said server is configured to determine, using at least the table, information for relaying the data element information update to at least a second, next highest priority database entity and a third database entity of lower priority than said second database entity;
wherein said server comprises a selector configured to select one of said at least three database entities for said specific data element based on the assigned priority,
wherein said server comprises a forwarder configured to forward said data element information update and said determined information to said selected database entity;
wherein each of said database entities is further configured such that said data element information update is forwarded to another database entity assigned a next highest priority relative to the database entity, where said selected database entity forwards said data element information update and at least a portion of the determined information to a second, next highest priority database entity of said at least three database entities, wherein said second, next highest priority database entity, using at least said portion of said determined information, forwards said data element information update to a third database entity of lower priority than said second database entity, said third database entity being one of said at least three database entities.
5. The system according to claim 4 , wherein said data element information comprises information related to a subscriber of a communication network.
