Synchronizing a channel codec and vocoder of a mobile station

Abstract

In one embodiment, the present invention includes a method for maintaining a vocoder and channel codec in substantial synchronization. The method may include receiving a configuration message that includes rate information and an effective radio block identifier at a mobile station, coding a current radio block via a vocoder and channel codec, configuring an encoding portion of the vocoder and channel codec with the rate information after performing the coding, and then coding the effective radio block using the rate information. Other embodiments are described and claimed.

1 . An apparatus comprising:
 a vocoder to encode an audio segment for a transmission; and   a channel codec coupled to the vocoder to further process the coded audio segment, wherein the vocoder and the channel codec are configured according to a predetermined priority to maintain the channel codec and the vocoder in substantial synchronization.   
     
     
         2 . The apparatus of  claim 1 , wherein the apparatus comprises a digital signal processor including the channel codec and the vocoder, and at least one of the channel codec and the vocoder comprises a software routine executed on the digital signal processor. 
     
     
         3 . The apparatus of  claim 1 , further comprising logic to first configure an encoding portion of the vocoder and an encoding portion of the channel codec according to a configuration message and to second configure a decoding portion of the vocoder and a decoding portion of the channel codec according to the configuration message. 
     
     
         4 . The apparatus of  claim 3 , wherein the logic is to configure the encoding portion of the vocoder prior to the encoding portion of the channel codec. 
     
     
         5 . The apparatus of  claim 4 , wherein the logic is to configure the decoding portion of the vocoder and the channel codec after decoding of an audio segment immediately prior to an effective audio segment set forth in the configuration message.
