Abstract

A radiotelephone device receiving network information, transmitted along a radio channel, from a network includes an acknowledgement coordination module determining a mode for exchange of acknowledgement information with the network. The radiotelephone device transmits the acknowledgement information to the network through a main dedicated control channel, using a defined service access point identifier corresponding to transmission of the acknowledgement information through the main dedicated control channel, in response to the mode for exchange of acknowledgement information being the main dedicated control channel. The radiotelephone device transmits the acknowledgement information to the network using a temporary block flow acknowledgement interchange in response to the mode for exchange of acknowledgement information being other than the main dedicated control channel.

Claims

1. A communication system, including a radiotelephone device transmitting acknowledgement information to a network, comprising:

a first acknowledgement coordination module, positioned within the network, transmitting an acknowledgement exchange message to the radiotelephone device indicating a mode for exchange of the acknowledgement information; and

a second acknowledgement coordination module, positioned within the radiotelephone device, transmitting the acknowledgement information to the network using the indicated mode,

wherein the radiotelephone device transmits the acknowledgement information along a main dedicated control channel in response to the indicated mode being the main dedicated control channel,

wherein the radiotelephone device transmits the acknowledgement information to the network using a temporary block flow acknowledgement interchange in response to at least one of the mode being other than the main dedicated control channel and the mode not being received,

wherein the network determines the mode for exchange of the acknowledgement information based on resource availability of the network, and

wherein the main dedicated control channel includes a defined service access point identifier corresponding to the acknowledgement information for transmission of the acknowledgement information through the main dedicated control channel.

2. The communication system of claim 1, wherein the network determines the mode for exchange of the acknowledgement information based on resource availability of the network.

3. The communication system of claim 1, wherein the network determines the mode for exchange of the acknowledgement information based on resource availability of the network and network congestion.

4. The communication system of claim 2, wherein the radiotelephone device includes an application interface transferring network protocol information to a corresponding application within the radiotelephone device, and wherein the second acknowledgement coordination module is positioned within the application interface.

5. The communication system of claim 4, wherein the network includes a transport layer interface transferring the network protocol information to the radiotelephone device, and wherein the first acknowledgement coordination module is positioned within the transport layer interface.

6. The communication system of claim 5, wherein the acknowledgement exchange message is included in a request for acknowledgement information transmitted from the network to the radiotelephone device.

7. The communication system of claim 6, wherein the acknowledgement exchange message is included in a packet downlink assignment message of a temporary block flow setup corresponding to the request for acknowledgement information transmitted from the network to the radiotelephone device.

8. A radiotelephone device receiving network information transmitted from a network along a radio channel, comprising:

an acknowledgement coordination module determining a mode for exchange of acknowledgement information with the network; and

a main dedicated control channel for transmitting signaling information to the network, wherein the radiotelephone device transmits the acknowledgement information to the network through the main dedicated control channel in response to the mode for exchange of acknowledgement information being the main dedicated control channel,

wherein the acknowledgement information is transmitted to the network using a temporary block flow acknowledgement interchange in response to at least one of the mode being other than the main dedicated control channel and the mode not being received, and

wherein the main dedicated control channel includes a defined service access point identifier corresponding to the acknowledgement information for transmission of the acknowledgement information through the main dedicated control channel.

9. The radiotelephone device of claim 8, wherein the network determines the mode for exchange of the acknowledgement information based on resource availability of the network and network congestion.

10. The radiotelephone device of claim 8, further comprising an application interface transferring network protocol information from the network to a corresponding application within the radiotelephone device, wherein the acknowledgement coordination module is positioned within the application interface.

11. The radio telephone device of claim 8, wherein the network is a GPRS/EDGE radio access network.

12. A method for exchange of acknowledgment information between a network and a user application, comprising the steps of:

attempting receive an acknowledgement exchange message including a mode for an exchange of acknowledgement information from the network; and

transmitting the acknowledgement information to the network along a main dedicated control channel using a service access point identifier in response to the mode being the main dedicated control channel.

13. The method of claim 12, further comprising determining the mode for exchange of the acknowledgement information based on resource availability of the network.

14. The method of claim 12, further comprising determining the mode for exchange of the acknowledgement information based on network congestion.

15. The method of claim 12, further comprising determining the mode for exchange of the acknowledgement information in an application interface that transfers network protocol information to a corresponding application.

16. The method of claim 12, wherein the acknowledgement exchange message is included in a request for acknowledgement information transmitted from the network to a radiotelephone device including the user application.

17. The method of claim 12, wherein the acknowledgement exchange message is included in a packet downlink assignment message of a temporary block flow setup corresponding to a request for acknowledgement information transmitted from the network to a radiotelephone device including the user application.
