Abstract

The present invention supports a communication protocol on a wireless communication network to allocate network resources. The radio network controller maintains quality of service (QoS) profiles. A serving node determines the type of application in a communication call and determines a QoS policy it transmits to the radio network. The radio network identifies the QoS profile based on the received policy and allocates network resources before announcing the call to an access terminal.

Claims

1. A packet-based wireless communication system, comprising:

a serving node on the system identifying the application of a communication call based on packet characteristics;

a radio network controller coupled to the serving node and controlling a radio network possessing at least one base transceiver station configured into at least one paging zone; and

said serving node communicating the application as a policy value designating a quality of service behavior type to the radio network controller, said radio network controller allocating the required network resources before announcing the call to a coupled access terminal.

2. The packet-based wireless communication system of claim 1, further comprising:

the radio network broadcasting a page message to the access terminal; and

upon receipt of a response to said page message, the radio network controller allocates network resources.

3. The packet-based wireless communication system of claim 2, further comprising:

the response to the page includes a connection request message.

4. The packet-based wireless communication system of claim 2, further comprising:

the response to the page includes a route update message.

5. The packet-based wireless communication system of claim 1, further comprising:

the radio network controller storing at least one data attribute associated with a quality of service profile, said profile associated with the policy value.

6. The packet-based wireless communication system of claim 1, further comprising:

the radio network controller creating a quality of service profile based on the policy value.

7. The packet-based wireless communication system of claim 1, further comprising:

the serving node assigning the policy value based on at least one of a source address, a destination address, the flow identification, a code value in a quality of service configuration, a source port number, or a destination port number.

8. A radio network in a packet-based wireless communication system, comprising:

a radio network controller coupled to a serving node and controlling a radio network possessing at least one base transceiver station configured into at least one paging zone;

the radio network controller receiving a quality of service policy value from a serving node on the system, the policy value used by the radio network controller to create a quality of service profile and, based on the profile, allocate the network resources required to support the quality of service upon receipt of a response to a page to a coupled access terminal.

9. The radio network in a packet-based wireless communication system of claim 8, wherein the policy type corresponds to a quality of service behavior type.

10. The radio network in a packet-based wireless communication system of claim 8, further comprising:

the response to the page includes a connection request message.

11. The radio network in a packet-based wireless communication system of claim 8, further comprising:

the radio network controller maintaining a data attribute associated with the quality of service profile, said profile corresponding to the quality of service policy value and associated with the resources required to deliver content and signaling of the communication call.

12. The radio network in a packet-based wireless communication system of claim 8, further comprising:

the policy value assigned based on at least one of a source address, a destination address, a flow identification, a code value in a quality of service configuration, a source port number, or a destination port number.

14. The method for allocating network resources on a packet-based wireless system of claim 12, further comprising the steps of:

broadcasting the page from a radio network coupled to the radio network controller to a wirelessly linked access terminal; and

receiving a page response at the radio network prior to resource allocation.

15. The method for allocating network resources on a packet-based wireless system of claim 12, further comprising the step of:

storing a data attribute associated with one quality of service profile on the radio network controller, said data attribute associated with a transmitted behavior type value.

16. The method for allocating network resources on a packet-based wireless system of claim 12, further comprising the step of:

allocating network resources using the radio network controller.

17. The method for allocating network resources on a packet-based wireless system of claim 12, further comprising the step of:

allocating network resources using the access terminal.

18. The method for allocating network resources on a packet-based wireless system of claim 12, further comprising the step of:

identifying the application based on at least one of a source address, a destination address, a flow identification, a code value in a quality of service configuration, a source port number, or a destination port number.

19. The method for allocating network resources on a packet-based wireless system of claim 12, wherein the behavior type is assigned based on at least one of a source address, a destination address, a flow identification, a code value in a quality of service configuration, a source port number, or a destination port number.

20. The method for allocating network resources on a packet-based wireless system of claim 19, wherein the serving node is selected from a group that includes a packet data serving node, a home subscriber server node, a call session control function, an application server, or a gateway node.

13. A method for allocating network resources on a packet-based wireless system, comprising the steps of:

identifying the application of a communication call based on packet characteristics and assigning a behavior type value;

receiving at a radio network controller coupled to a radio network the behavior type value, and said radio network controller associating the behavior type value with a quality of service required to deliver content and signaling of the communication call;

assigning network resources based on a quality of service profile generated by the radio network controller and associated with said quality of service, said resources allocated after receiving a response to a page transmitted to an access terminal and before announcing the call to the access terminal; and

generating the quality of service profile based on the behavior type value.
