Patent number: 7715875Abstract: Disclosed is a base station controller including processing units classified into a C-plane, a U-plane, and a T-plane. A plurality of subunits are provided in each plane, each subunit having a controller and a plurality of processing entities. Each controller of each subunits maintains a table which indicates the relationship among a name of the message transmitted and received by the C-plane to and from the outside in order to set up a call, a service identifier of the call which is set up using the message; and a name of the process entity which processes the call. Upon detection of a call failure, each plane controller searches the table with a message name, a user identifier, and a service identifier of the call. Then, each plane controller outputs alarm information including the user identifier, a subunit identifier, and the process entity name into a storage device.Type: GrantFiled: March 17, 2006Date of Patent: May 11, 2010Assignee: NEC CorporationInventor: Ayako Kato
