Limiting processing of calls as text telephony calls
First Claim
1. A method performed by a communication node for processing a call supported over a voice coded channel in a wireless communication network, the method comprising:
- tentatively designating the call as a voice call as soon as the call is initiated;
while the call is designated as a voice call, limiting processing of the call as a text telephony call to passively monitoring for one or more partial or complete text characters in the call;
responsive to detecting one or more partial or complete text characters in the call via said passive monitoring, designating the call as a text telephony call; and
while the call is designated as a text telephony call, fully processing the call as a text telephony call by passively detecting one or more complete text characters in the call as well as conditioning and de-conditioning signals of the call for reliable transmission and reception over the voice coded channel;
wherein the communication node is configured to process multiple calls, and wherein the method further comprises, responsive to said detection via said passive monitoring, releasing resources at the communication node performing said limited processing and selecting a resource for performing said fully processing from a pool of shared resources that are available at the communication node for fully processing a subset of the multiple calls processed by the communication node.

Abstract
A communication node processes a call supported over a voice coded channel in a wireless communication network. The node tentatively designates the call as a voice call as soon as the call is initiated. While the call is designated as a voice call, the node limits processing of the call as a text telephony call to passively monitoring for one or more partial or complete text characters in the call. Responsive to detecting one or more partial or complete text characters in the call via this passive monitoring, the node designates the call as a text telephony call. While the call is designated as a text telephony call, the node fully processes the call as a text telephony call by passively detecting one or more complete text characters in the call, and conditioning and de-conditioning signals of the call for reliable transmission and reception over the voice coded channel.

13. A communication node configured to process a call supported over a voice coded channel in a wireless communication network, the communication node comprising:
-
one or more communication interfaces configured to transmit and receive signals of the call over the voice coded channel; and one or more processing circuits configured to; tentatively designate the call as a voice call as soon as the call is initiated; while the call is designated as a voice call, limit processing of the call as a text telephony call to passively monitoring for one or more partial or complete text characters in the call; responsive to detecting one or more partial or complete text characters in the call via said passive monitoring, designate the call as a text telephony call; and while the call is designated as a text telephony call, fully process the call as a text telephony call by passively detecting one or more complete text characters in the call as well as conditioning and de-conditioning signals of the call for reliable transmission and reception over the voice coded channel; wherein the communication node is configured to process multiple calls, and wherein the one or more processing circuits are configured, responsive to said detection via said passive monitoring, to release resources at the communication node performing said limited processing and select a resource for performing said fully processing from a pool of shared resources that are available at the communication node for fully processing a subset of the multiple calls processed by the communication node. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
