Patent ID: 7738446

Claim:
A method for determining a usage of Digital Signal Processing (DSP) resources in a communication network, comprising: receiving at a Call Control Element (CCE) a call setup message to setup a call; determining at least one DSP server from a plurality of DSP servers that incurs a lowest overall DSP cost for supporting said call, wherein said plurality of DSP servers is deployed within said communication network, wherein said determining comprises: determining an originating border element (BE) and a terminating BE to be used to support said call; identifying a plurality of overall DSP costs of using various available DSP servers associated with said originating BE and said terminating BE; and determining said at least one DSP server that incurs said lowest overall DSP cost associated with said originating BE and said terminating BE, wherein said at least one DSP server that incurs the lowest overall DSP cost associated with said originating BE and said terminating BE is determined by a DSP Network Map Application Server, wherein said originating BE and said terminating BE are provided by said Call Control Element (CCE) to said DSP Network Map Application Server to determine said at least one DSP server that incurs said lowest overall DSP cost associated with said originating BE and said terminating BE; and establishing by said CCE said call using said at least one DSP server.
