A method and apparatus for preparing a vendor- and version-independent information model that a cellular telephone base station can use to communicate its capabilities in a plug and play fashion to a network element is disclosed. The information model can also be used to communicate configuration information back to the base station from the network element. The capabilities and configuration information is automatically communicated and utilized, thus reducing the possibility of human operator error in configuring and pre-configuring new or modified base station equipment.

Open 'plug and play' O and M architecture for a radio base station

A method, system, and apparatus enables automatic radio base station (RBS) rehoming from a first radio network controller (RNC) to a second RNC when the first RNC becomes overloaded and/or automatic resource sharing between/among RNCs when one RNC becomes overloaded. A managing/controlling entity receives load measuring reports from RNCs and analyzes them. If a first RNC is frequently and/or constantly experiencing an overcapacity condition, then an RBS of the RNC may be rehomed to a second RNC without operator intervention. If a first RNC temporarily experiences an overcapacity condition, then the workload of the first RNC may be shared by a second RNC also without operator intervention. When rehoming an RBS or sharing a load of a first RNC, ongoing connections are completed by the first RNC where the connection was initiated, but new connections are (for the rehoming case) or new connections may be (for load sharing cases) initiated using a second RNC.

Rehoming and resource sharing in communications networks

A system and method for distributing the fault management functions throughout a communications network. Each node in the network includes an associated fault agent/configuration agent pair. The fault agent receives alarm information and correlates the alarm information to identify a cause of a fault in the network. The fault agent then determines if correction of the fault can be handled at the current node. If so, the fault agent passes information identifying the fault to the associated configuration agent, which generates reconfiguration data for handling the fault and sends the reconfiguration data to subordinate nodes for implementation. If, on the other hand, the fault agent determines that the fault cannot be handled at the current node, the fault agent passes the alarm data, in summary form, to a higher level fault agent/configuration agent pair for handling at that higher level or for further processing and passing the data up the network until a level is reached at which the fault can be handled.
