Abstract

A method, system, and computer program product for providing communications services, including determining a type of communications service present in a communications session based on quality of service parameters assigned for the communications session; and adjusting the quality of service parameters based a different type of communications service requested. The types of communications services include real-time and non-real-time communications services.

Claims

1. A method for providing communications services, comprising:

determining a type of communications service present in a communications session based on the quality of service parameters assigned for the communications session, wherein the types of communications services include real-time voice over Internet Protocol (IP) services, and non-real-time data services;

adjusting the quality of service parameters based on a different type of communications service requested;

handling both data services and voice over IP services under a single set of quality of service parameters; and

informing a base station of establishment of the voice over IP services upon detection of an ensuing voice over IP call in a separate message.

2. The method of claim 1, further comprising:

inspecting a transport address of a message from a terminal equipment to a mobile terminal to determine the ensuing voice over IP call.

3. A method for providing communications services, comprising:

determining a type of communications service present in a communications session based on the quality of service parameters assigned for the communications session, wherein the types of communications services include real-time voice over Internet Protocol (IP) services, and non-real-time data services;

adjusting the quality of service parameters based on a different type of communications service requested; and

concurrently provisioning quality of service parameters for both voice over IP services and data services over the communications system, including,

generating a voice IP address for voice over IP communications between a mobile terminal and a communications system,

employing a device IP address of a terminal equipment for voice over IP or data communications between the mobile terminal and the terminal equipment, and

employing the device IP address for data communications between the mobile terminal and the communications system.

4. The method of claim 3, further comprising:

activating first quality of service parameters comprising a first packet data protocol context applicable to the data services based on the device IP address, and

activating second quality of service parameters comprising a second packet data protocol context applicable to the voice over IP services based on the IP address for voice over IP.

5. A method for providing communications services, comprising:

determining a type of communications service present between a mobile terminal and a communications system in a communications session based on the quality of service parameters assigned for the communications session, wherein the types of communications services include real-time voice over Internet Protocol (IP) services, and non-real-time data services;

adjusting the quality of service parameters based on a different type of communications service requested; and

generating different temporary block flows for voice over IP services and data services, respectively, including,

generating, in parallel, a first temporary block flow for an acknowledged mode radio link control transport and a second temporary block flow for an unacknowledged mode radio link control transport.

6. The method of claim 5, further comprising:

generating different temporary flow identifiers for the first and second temporary block flows.

7. A method for providing communications services, comprising:

determining a type of communications service present in a communications session based on the quality of service parameters assigned for the communications session, wherein the types of communications services include real-time voice over Internet Protocol (IP) services, and non-real-time data services;

adjusting the quality of service parameters based on a different type of communications service requested; and

determining that a temporary block flow is requesting the voice over IP services, if a temporary block flow is requested to be established in an unacknowledged radio link control transport mode and a high radio priority mode.

8. The method of claim 7, further comprising:

applying an admission control mechanism based on available resources for the voice over IP services to one of accept and reject the requested voice over IP services.

9. The method of claim 7, further comprising:

generating a highest level of data-scheduling priority over a communications system for the unacknowledged radio link control transport mode.

10. The method of claim 7, further comprising:

multiplexing data packets for data services during silence intervals in the voice over IP services.

11. A method for providing communications services, comprising:

determining a type of communications service present in a communications session based on the quality of service parameters assigned for the communications session, wherein the types of communications services include real-time voice over Internet Protocol (IP) services, and non-real-time data services;

adjusting the quality of service parameters based on a different type of communications service requested; and

assigning packets having an unacknowledged radio link control transport mode higher priority than packets having an acknowledged radio link control transport mode.

12. The method of claim 11, further comprising:

assigning voice over IP channel resources to the packets having the unacknowledged radio link control transport mode.
