One architecture for a Base Station Controller (BSC) in a wireless infrastructure network involves the use of smaller servers which, when pooled, can act as a resource pool for providing signaling services to mobile subscribers. The BSC server is one type of an application server in an Internet Protocol (IP) signaling framework. Signaling messages from a Signaling System 7 (SS7) network may undergo a protocol and address translation in a gateway to access one of the available servers in the BSC Server Pool. Proposed standards suggest the use of a load distribution function between the gateway and one of a set of application servers. The load distribution function discussed usually is based on static associations known at the gateway when the application servers in the IP domain register their ability to accept service requests. The registration and load distribution functions do not necessarily consider the capacity of each registered server nor it’s availability to provide service when requested. This publication describes a mechanism by which the gateway can monitor the server’s availability and capacity in a dynamic manner so that service requests are directed to the appropriate servers in a pool.
