Embodiments relate to a communication system comprising a call handler arranged to process channel signalling received from a communication network; a workload controller comprising means to determine the workload of at least one processing resource of the communication system; wherein the call handler comprises means to block establishment of at least one channel in response to the workload of the at least one processing resource.

Blocking a channel in a communication system

According to one embodiment of the present invention there is provided a communication method comprising the steps of making a determination in respect of at least initiating a first call between first and second communication devices having first and second contact numbers respectively; said making the determination comprising identifying at least one of the first and second contact numbers associated with said initiating, accessing a database comprising at least a first monitored contact number and at least one associated third party number corresponding to a third communication device, determining whether or not at least one of a first contact number and the second contact number match the first monitored contact number; and establishing, in response to the determination, a third party call to the third communication device.

Communication system and method

In a computer system with a virtual addressing mechanism, a process for the de-allocation of physical pages sets, by means of a first pointer (ptr) on a line ( ) of a conversion table ( ) that contains an indicator (Ref) that has been set to a first state (&ldquo;referenced&rdquo;) by a processor ( ), the indicator (Ref) to a second state (&ldquo;non-referenced&rdquo;) if the state is (&ldquo;referenced&rdquo;) and de-allocates the line ( ) if the state is (&ldquo;non-referenced&rdquo;). The de-allocation process claimed by the invention sets an indicator (ref) which has been set to the first state (&ldquo;referenced&rdquo;) by the processor ( ) on a line ( ) of the conversion table ( ) to a second state (&ldquo;non-referenced&rdquo;) if the state is (&ldquo;referenced&rdquo;) by means of a second pointer (ptr&plus;&Dgr;) on the line ( ) upon the indication of an attribute value (Co) for said line ( ). The de-allocation process can therefore be used for a cache mechanism.
