Abstract

A wireless telecommunications network includes a base station controller which includes a call control resource manager and a multi-function coding element embodied within a DSP and comprised of first, second and third coding resources, each embodied as a software module, for respectively performing D/A and A/D on voice, facsimile and data messages. When transferring messages from a mobile terminal to an MSC via the base station controller, the mobile terminal first informs the base station controller whether the message is a voice, facsimile or data message. The mobile terminal then transfers the message to the call control resource manager residing within the base station controller. Based upon the indicated message type, the call control resource manager selects, from the first, second and third coding resources, a resource for performing a D/A conversion of the message received from the mobile terminal. After the selected resource performs the D/A conversion of the received message, the call control resource manager transfers the converted message to the MSC. Conversely, when transferring messages from the MSC to a selected mobile terminal via the base station controller, the MSC informs the base station controller whether the message is a voice, facsimile or data message. The MSC then transfers the message to the call control resource manager. Based upon the indicated message type, the call control resource manager selects one of the first, second and third coding resources to perform an A/D conversion of the received message. The call control resource manager will then transfer the converted message to the selected mobile terminal.
