Abstract

At least one transmission condition associated with making a transmission of pre-cache data over a transmission leg (112 or 114) of a network is obtained. A priority for transmitting the pre-cache data is determined using the transmission condition.

Claims

1. A method of assigning a priority to a transmission leg in a network comprising:

obtaining at least one transmission condition associated with making a transmission of pre-cache data over a transmission leg of a network; and

determining a priority for transmitting the pre-cache data using the at least one transmission condition.

2. The method of claim 1 wherein determining a priority comprises determining an identity of packets within the pre-cache data and an identity of a base station to which to send the packets.

3. The method of claim 2 further comprising scheduling the sending of the pre-cache data to the base station according to the priority.

4. The method of claim 1 further comprising determining an amount of packets to be transmitted to the base station based upon the priority.

5. The method of claim 4 wherein determining an amount comprises determining an amount that is related to a data rate of the transmission leg and a cell reselection time associated with the transmission leg.

6. The method of claim 1 wherein obtaining the at least one transmission condition comprises receiving transmission information that is related to a condition of the transmission leg.

7. The method of claim 6 wherein receiving the transmission information comprises receiving information related to a condition of the transmission leg, the condition being selected from a group comprising:

an amount of backhaul loading on the transmission leg;

a time of day;

a Radio Frequency (RF) delay on the transmission leg and a time of day;

whether the transmission leg is a candidate for a group call;

whether a signal strength is lower in the transmission leg as compared to another transmission leg;

an indication that a packet is of a high priority and has not been downloaded to a site;

an amount of backhaul loading at a given time;

an amount of Radio Frequency (RF) loading at a given time;

an amount of Radio Access Node (RAN) loading at a given time;

a buffer level on a transmission leg and a buffer level at a playout buffer at a mobile station;

a length of a cell reselection time on a transmission leg;

whether extra buffer space exists;

whether the transmission leg has a different associated base station controller than a primary leg; and

a number of mobiles connected to the transmission leg.

8. The method of claim 1 wherein obtaining the at least one transmission condition comprises receiving transmission information that is related to a condition of a mobile station.

9. The method of claim 8 wherein receiving transmission information comprises receiving transmission priority information selected from a group comprising:

a battery life of the mobile station;

a location of the mobile station;

a velocity of the mobile station;

a direction of movement of the mobile station;

a number of transmission legs with which the mobile station has established a connection;

a volume of traffic at the mobile station;

a time stayed on the transmission leg by the mobile station is high;

a promotional plan used at the mobile station;

whether the mobile station belongs to a high-priority group;

an identity of a preferred application being run by the mobile station; and

whether the mobile station is a 802.11 compatible access point.

10. The method of claim 1 wherein obtaining the at least one transmission condition comprises receiving transmission information that is related to a condition of a call.

11. The method of claim 10 wherein receiving the transmission information comprises receiving transmission information associated with a call condition, the condition being selected from a group comprising:

whether the call is an emergency call;

a security level associated with the call;

an identity of a premium application associated with a call;

an identity of a streaming application;

an identity of a delay-sensitive application;

an identity of a file transmission over a primary transmission leg that is near the end of a file;

an identity of a file transmission over a primary transmission leg experiences excessive delay and times out;

information indicating a received data rate is below a threshold; and

whether a call is undergoing a handoff between different types of equipment.

12. The method of claim 1 wherein obtaining the at least one transmission condition comprises receiving transmission information that is related to a condition of a user.

13. The method of claim 12 wherein receiving the transmission information comprises receiving transmission information related to a condition of the user, the condition of the user being selected from a group comprising:

whether the user is a premium user;

a type of bill plan associated with the user;

a type of equipment utilized by the user; and

a frequency of network use by the user.

14. The method of claim 1 further comprising applying data compression to the pre-cache data on the transmission leg whenever a low priority for the at least transmission one leg is determined.

15. The method of claim 1 further comprising determining whether a number of mobile stations are likely to substantially simultaneously initiate a handoff and, responsively, to initiate pre-filling.

16. The method of claim 15 wherein the determining comprises determining from received information, the information selected from a group comprising:

information indicating previous handoffs were made at substantially the same time by the number of mobile stations;

information indicating the number of mobile stations are on a same conveyance; and

information indicating that a traffic signal has changed which will result in a correlated handoff event.

17. A device for determining a priority for transmitting data on a transmission leg of a network comprising:

a receiver having an input;

a transmitter having an output; and

a controller coupled to the receiver and the transmitter, the controller programmed to receive at the input of the receiver at least one transmission condition associated with making a transmission of pre-cache data using a transmission leg of a network and to determine a priority for transmitting the pre-cache data using the at least one transmission condition.

18. The device of claim 17 wherein the at least one transmission condition is selected from a group comprising:

a condition of the transmission leg;

a condition of a user;

a condition of a mobile station; and

a condition of a call.

19. A system for prioritizing the transmission legs of a network comprising:

at least one base station; and

a base station controller coupled to the at least one base station, the base station controller programmed to obtain at least one transmission condition associated with making a transmission of pre-cache data via a transmission leg in a network and to determine a priority for transmitting the pre-cache data using the at least one transmission condition.

20. The system of claim 19 wherein the base station controller is further programmed to send the pre-cache data to the at least one base station according to the priority.
