Telecommunications network and method for routing incoming calls for MTC services

摘要

If, during the initialization of an MTC service for a subscriber (TNB) to a telecommunications network which is in the form of a an overlay network, the performance required to carry out the service exceeds the performance level supported by the access SSP node (SS1), the service control point (SCP) uses the call address to produce a routing address which contains information relating to further routes of the call to a second SSP node (SS2) which supports the required performance level, and transmits (5) this to the first SSP node (SS1) for passing it on.
