Method and system for providing integrated data services to increase spectrum efficiency
View Patent ↗A method and system of sending supplemental information during a telecommunications session includes the step ( 305 ) of detecting a period of silence within the telecommunications session. The period of silence can be detected from at least one member of the telecommunications session. Comfort noise can be specified within at least one time slot ( 205 ) of a plurality of consecutive time slots ( 205, 210 ) for a channel over which the period of silence is detected. For at least one other time slot of the channel ( 210 ), non-voice data is specified such that the channel includes both comfort noise and other non-voice data during the period of silence. The consecutive time slots ( 205, 210 ) can be associated with a data block ( 200 ). The non-voice data can be a data payload of the other time slot ( 210 ).
1. A method of sending supplemental information during a telecommunications session comprising the steps of:
detecting a period of silence within the telecommunications session;
specifying comfort noise within at least one of a plurality of consecutive time slots for a channel over which said period of silence is detected, wherein the channel includes both unlink and downlink connections; and
for at least one other time slot of said channel, specifying non-voice data such that said channel includes both comfort noise and other non-voice data during said period of silence on both the uplink and downlink connections.
2. The method according to claim 1 , wherein said plurality of consecutive time slots are associated with a data block.
3. The method according to claim 1 , wherein said non-voice data is specified by a fixed network device.
4. The method according to claim 3 , wherein said fixed network device transmits said non-voice data to a communications device.
5. The method according to claim 1 , wherein said non-voice data is specified by a communications device.
6. The method according to claim 5 , wherein said communications device is a mobile communications device.
7. The method according to claim 5 , wherein said communications device transmits said non-voice data to a communications network or another communications device.
8. The method according to claim 1 , further comprising the step of providing said non-voice data as a data payload of said at least one other time slot.
9. The method according to claim 8 , further comprising the step of signaling that said non-voice data is provided as said data payload.
10. The method according to claim 9 , wherein said signaling step comprises the step of modifying a header associated with said at least one other time slot.
11. The method according to claim 10 , wherein said signaling step further comprises the step of inserting an identifier into a channel identification field associated within said header.
12. The method according to claim 11 , wherein said identifier comprises a single bit of data.
13. The method according to claim 10 , wherein said header is a slot descriptor block.
14. The method according to claim 1 , wherein said non-voice data is provided in a circuit data format.
15. The method according to claim 1 , wherein said at least one other time slot is a time slot allocated for said non-voice data.
16. The method according to claim 1 , wherein said period of silence is detected from at least one member of said telecommunications session.
17. A system of sending supplemental information during a telecommunications session comprising:
a first communication device having a processor programmed to:
detect a period of silence within the telecommunications session; and
specify comfort noise within at least one of a plurality of consecutive time slots for a channel over which said period of silence is detected, wherein the first communication device specifies the comfort noise for an uplink connection of the channel; and
a second communication device having a processor programmed to:
for at least one other time slot of said channel, specify non-voice data such that said channel includes both comfort noise and other non-voice data during said period of silence, wherein the second communication device specifies the non-voice data for a downlink connection of the channel.
18. The system of claim 17 , wherein the first communication device is selected from a group comprising a mobile cellular phone, a smartphone, and a combined personal digital assistant and a mobile phone.
19. A system of sending supplemental information during a telecommunications session comprising:
a communication device having a processor programmed to:
detect a period of silence within the telecommunications session;
specify comfort noise within at least one of a plurality of consecutive time slots for a channel over which said period of silence is detected, wherein the channel includes both unlink and downlink connections; and
for at least one other time slot of said channel, specify non-voice data such that said channel includes both comfort noise and other non-voice data during said period of silence on both the unlink and downlink connections.
20. The system of claim 19 , wherein the communication device is selected from a group comprising a mobile cellular phone, a smartphone, and a combined personal digital assistant and a mobile phone.
21. The system of claim 19 , wherein the system further comprises a second communication device that specifies additional non-voice data during said period of silence.
