Abstract

A network controller or base station (502), allocates resources and indicates a minimum priority level below which, mobile stations may not transmit data via messaging (503). Messaging (503) may be a scheduling message in some embodiments. The network controller or base station (502) also communicates a data timer setting for timing sub-minimum priority data via messaging (505). Messaging (505) may be a control message in some embodiments. The mobile station (501) responds by setting a data timer (507) and holding data with a priority below the specified minimum. Before the timer times out, the mobile station (501) may transmit data on granted resources via (509) provided its priority level is above the specified minimum. After timer expiration, the mobile station (501) may transmit its low priority data, or combinations of high and low priority data (511).

Claims

1. A method of operating a network infrastructure entity, the method comprising:

mapping a set of data priorities to a set of radio bearers, each of said radio bearers of said set of radio bearers corresponding to a data priority of said set of data priorities;

setting a minimum data priority below which low priority data having a priority below said minimum data priority should not be transmitted over any of said radio bearers, wherein said data is associated with a service;

sending said minimum data priority to a mobile station along with a resource allocation, wherein prioritized data having a priority equal to or above said minimum data priority is allowed to be transmitted by said mobile station using said resource allocation;

setting, by said network infrastructure entity, a time limit for which said mobile station may buffer said low priority data, wherein said mobile station may transmit said low priority data using said resource allocation after said time limit expires; and

sending said time limit from said network infrastructure entity to said mobile station.

2. The method of claim 1, wherein sending said time limit to said mobile station further comprises:

sending said time limit to said mobile station in a control message.

3. The method of claim 1, wherein sending said minimum data priority to a mobile station along with a resource allocation further comprises sending a scheduling message.

4. The method of claim 1, wherein said time limit set by said network infrastructure entity is dynamically determined based upon network conditions.

5. A method in a mobile station, the method comprising:

buffering a first set of data having a first priority and a second set of data having a second priority lower than said first priority;

receiving a resource allocation for transmitting said first set of data and said second set of data;

receiving a priority minimum below which data should not be transmitted;

receiving, from a base station, a time setting for which data having a priority below said priority minimum should not be transmitted and setting a timer according to said time setting;

determining whether said second set of data has a priority above or below said priority minimum;

receiving a data percentage indicating an allowable data percentage of buffered said priority minimum data, that is allowed to be transmitted;

transmitting said second set of data using said resource allocation if said second priority is equal to or above said priority minimum; and

holding said second set of data if said second priority is below said priority minimum, transmitting said allowable data percentage of said second set of data after said timer expires, and continuing to buffer data having a priority below said priority minimum.

6. The method of claim 5, wherein receiving a priority minimum below which data should not be transmitted, further comprises receiving a scheduling message having said priority minimum.

7. The method of claim 5, wherein receiving a time setting for which data having a priority below said priority minimum should not be transmitted, further comprises receiving a control message having said time setting.

8. A mobile station comprising:

at least one transceiver;

at least one processor coupled to said transceiver;

said transceiver and said processor configured to;

buffer a first set of data having a first priority and a second set of data having a second priority lower than said first priority;

receive a resource allocation for transmitting said first set of data and said second set of data;

receive a priority minimum below which data should not be transmitted;

receive, from a base station, a time setting for which data having a priority below said priority minimum should not be transmitted and set a timer according to said time setting;

determine whether said second set of data has a priority above or below said priority minimum;

receive a data percentage indicating an allowable percentage of data stored by said buffer, said data having a priority lower than said priority minimum, that is allowed for transmission;

transmit said second set of data using said resource allocation if said second priority is equal to or above said priority minimum; and

hold said second set of data if said second priority is below said priority minimum, transmit said allowable data percentage of said second set of data after said timer expires, and continue to buffer data having a priority below said priority minimum.

9. The mobile station of claim 8, wherein said transceiver and said processor are further configured to receive said priority minimum below which data should not be transmitted, by receiving a scheduling message having said priority minimum.

10. The mobile station of claim 8, wherein said transceiver and said processor are further configured to receive said time setting for which data having a priority below said priority minimum should not be transmitted, by receiving a control message having said time setting.

11. A base station comprising:

a transceiver;

a processor coupled to said transceiver, said transceiver and said processor configured to;

map a set of data priorities to a set of radio bearers, each of said radio bearers of said set of radio bearers corresponding to a data priority of said set of data priorities, said set of radio bearers further corresponding to said resource allocation;

set a minimum data priority below which low priority data having a priority below said minimum data priority should not be transmitted over any of said radio bearers, wherein said data is associated with a service;

send said minimum data priority to a mobile station along with a resource allocation, wherein prioritized data having a priority equal to or above said minimum data priority is allowed to be transmitted by said mobile station using said resource allocation;

setting a time limit for which said mobile station may buffer said low priority data, wherein said mobile station may transmit said low priority data using said resource allocation after said time limit expires; and

sending said time limit to said mobile station.

12. The base station of claim 11, wherein said transceiver and said processor are further configured to:

send said time limit to said mobile station in a control message.

13. The base station of claim 12, wherein said transceiver and said processor are further configured to send a data percentage indicating a percentage of data stored by said buffer, said data having a priority lower than said priority minimum, for transmission after said timer expires.

14. The base station of claim 12, wherein said data is a plurality of protocol data units.

15. The base station of claim 11, wherein said transceiver and said processor are further configured to send said minimum data priority to said mobile station along with a resource allocation by sending a scheduling message.
