<p>A method of selecting call mediation node by soft switch device is provided in the embodiment of the present invention, which includes the following steps: receiving the coding/decoding information; judging whether the coding/decoding information is included in the coding/decoding intersection of the forward office and the backward office; performing in the manner of call mediation node CMN, if the coding/decoding information is included in the intersection. A system and deviace of selecting call mediation node by soft switch device is also provided in the present invention. For the cross-area call in the same operator, at the interworking node of CS area and IMS/NGN network, the interworking MSC server applies the CMN manner if there is a common code/decode negotiated by CS area and IMS/NGN network, so as to improve the call succeeded speed greatly, and increase the device processing capacity.</p> |
