A call connection management equipment for decreasing the required time from a call connection request to a call connection establishment in a wireless mobile communication network. This call connection management equipment registers generated call connection information to a connection registration part, and stores call connection history, such as connection count. The call connection management equipment uses the already registered connection information when the call connection history satisfies a predetermined condition, and generates a new connection information when the call connection history does not satisfy the predetermined condition. When the predetermined condition is not satisfied, the connection information is deleted. The connection information is also deleted when a wireless base station to accommodate a calling terminal is switched, or when an interface to accommodate a called terminal is switched.
