Method of routing signals through communication networks

摘要

In a communication network, every subscriber has among all the calls he originates one or more call groups he frequently calls. To avoid repetitive call processing, the network allows for a more efficient call processing using the routing information of a previous call to the same subscriber. This allows a network element such as a switch to use existing routing information for the next same call instead of determining the routing information each time anew. The network and a method implemented therein identify the one or more call groups, store the routing information for these call groups, and use the stored routing information for the next same-call establishment.
