Abstract

In the present technique of data transmission management provided, a composite status indicator value is assessed (716) based on multiple channel quality indicator reports over a predefined time. The assessed composite status indicator value is compared (718) to a first threshold value. If the assessed composite status indicator value does not correspond in at least a predetermined way to the first threshold value, the mobile station is classified (720) in a high speed data region. Otherwise, the assessed composite status indicator value is further compared (726) to a second threshold, and if it corresponds in at least a predetermined way to the second threshold, the mobile station is classified (734) in the low speed data region.

Claims

1. A method of managing data transmission of a mobile station between a high speed data region and a low speed data region comprising:

assessing a composite status indicator value to provide an assessed composite status indicator value that is based on a plurality of channel quality indicator reports according to a predefined time;

determining whether the assessed composite status indicator value corresponds in at least a predetermined way to a first threshold value;

classifying the mobile station in a high speed data region when the assessed composite status indicator value does not correspond in at least the predetermined way to the first threshold value;

determining whether the assessed composite status indicator value corresponds in at least a predetermined way to a second threshold value when the assessed composite status indicator value corresponds in at least the predetermined way to the first threshold value;

classifying the mobile station in the low speed data region when the assessed composite status indicator value corresponds in at least the predetermined way to the second threshold value.

2. The method according to claim 1 further comprising:

classifying the mobile station in a handover data region when the assessed composite status indicator value does not correspond in at least the predetermined way to the second threshold value.

3. The method according to claim 2, wherein classifying the mobile station in the handover data region further comprises:

determining whether a handover message has been received;

initiating a handover of the mobile station when a handover message has been received;

repeating assessing a composite status indicator value based on a plurality of channel quality indicator reports according to a predefined time when a handover message has not been received.

4. The method according to claim 1 further comprising, wherein prior to assessing the composite status indicator value:

receiving a channel assignment message to set up the mobile station for a high speed shared data channel;

activating the mobile station on a base station scheduler active user list;

receiving data packets for the mobile station;

receiving the plurality of channel quality indicator reports from the mobile station.

5. The method according to claim 1, wherein assessing a composite status indicator value based on a plurality of channel quality indicator reports according to a predefined time further comprises:

collecting related information of the mobile station, wherein the assessed composite status indicator value is further based on collected related information.

6. The method according to claim 5, wherein the collected related information comprises any one or more selected from a group of a user averaged data throughput, an amount of data available in a user data buffer, a number of active users, and a length of time that user data stayed in the user data buffer.

7. The method according to claim 1, wherein classifying the mobile station in the high speed data region further comprises:

scheduling the mobile station on a high speed shared data channel.

8. The method according to claim 1, wherein classifying the mobile station in the low speed data region further comprises:

scheduling the mobile station on a low speed non-shared data channel.

9. The method according to claim 1, wherein classifying the mobile station in the low speed data region further comprises:

rescheduling the mobile station to a low speed non-shared data channel;

determining whether a high speed shared data channel deactivation message has been received;

assigning the mobile station to the low speed non-shared data channel when the high speed shared data channel deactivation message has been received.

10. A method of managing data transmission of a mobile station between a high speed shared data channel defined in a high speed data region and a low speed non-shared data channel defined in a low speed data region comprising:

receiving a plurality of channel quality indicator reports from the mobile station;

assessing a composite status indicator value based on the plurality of channel quality indicator reports according to a predefined time to provide an assessed composite status indicator value;

determining whether the assessed composite status indicator value corresponds in at least a predetermined way to a threshold;

determining whether the assessed composite status indicator value falls in the high speed data region for a predefined period of time when the assessed composite status indicator value corresponds in at least the predetermined way to the threshold;

scheduling the mobile station in the high speed shared data channel when the assessed composite status indicator value falls in the high speed data region for the predefined period of time.

11. The method according to claim 10 further comprising:

continuously monitoring the plurality of channel quality indicator reports from the mobile station when the assessed composite status indicator value does not correspond in at least the predetermined way to the threshold.

12. The method according to claim 10, wherein scheduling the mobile station in the high speed shared data channel further comprises:

sending a request to schedule the mobile station in the high speed shared data channel;

determining whether the request has been accepted;

setting up the high speed shared data channel for the mobile station when the request has been accepted;

continuously monitoring the plurality of channel quality indicator reports from the mobile station when the request has not been accepted.

13. The method according to claim 12 further comprising:

receiving a high speed shared data channel packet for the mobile station;

deactivating the mobile station from the low speed non-shared data channel at a specified time;

rescheduling the mobile station on the high speed shared data channel.

14. A method of managing data transmission of a mobile station between a high speed shared data channel and a low speed non-shared data channel comprising:

receiving a request to redirect the mobile station from the high speed shared data channel to the low speed non-shared data channel;

determining whether a coding scheme of the low speed non-shared data channel is available;

sending an accept message to the request when the coding scheme of the low speed non-shared data channel is available;

sending a message to indicate that the coding scheme of the low speed non-shared data channel is unavailable when the coding scheme of the low speed non-shared data channel is not available.

15. The method according to claim 14 further comprising, wherein prior to receiving the request to redirect the mobile station from the high speed shared data channel to the low speed non-shared data channel:

receiving a request to be directed to the high speed shared data channel from the mobile station;

sending a request to set up the high speed shared data channel responsive to the request;

sending a data packet on the high speed shared data channel for the mobile station.

16. The method according to claim 14, wherein sending the accept message to the request further comprises:

sending a low speed data call message to redirect the mobile station to the low speed non-shared data channel.
