Abstract: A communication system provided with a radio access network including a plurality of RATs, comprises: a first RAT for an initial access by a terminal; and at least one individual RAT different from the first RAT, wherein in accordance with a service provided to the terminal, switching from the first RAT to the individual RAT is performed for subsequent processing after the initial access, in accordance with a service to be provided to the terminal.

Abstract: In a connection admission controlling system, a call admission processing and allocating device judges whether or not a call is admitted in response to a peak rate of a traffic and allocates, as a temporary bandwidth, the peak rate to the call when the call is admitted. A resource controlling device has a connection call controlling table which holds call connection data of calls each of which has at least one of the temporary bandwidth and an effective bandwidth. A traffic measuring device measures a traffic of the call to produce a measured traffic. An effective bandwidth computing and allocating device has a new call controlling table which holds new call connection data representing data of calls each of which have the temporary bandwidth. The effective bandwidth computing and allocating device computes the effective bandwidth by using the measured traffic and allocates the effective bandwidth to the call.
