Abstract

A method for determining a GPRS mobile terminal connection mode is disclosed. Whenever a GPRS data service is requested, a mobile terminal counts the number of attempted of GPRS connections and the number of successful GPRS connections to calculate a GPRS connection rate, compares the calculated connection rate with a predetermined connection rate. If the calculated connection rate is greater than the predetermined connection rate, the mobile terminal changes the GPRS connection mode to a ‘when needed mode’, whereas if the calculated connection rate is not greater than the predetermined connection rate, the mobile terminal changes the GPRS connection mode to an ‘always on mode’. Accordingly, by changing the connection mode in a GPRS network, network resources can be better utilized and the connection rates can be increased.

Claims

1. A method for changing a mobile terminal GPRS connection mode, the method comprising:

calculating a GPRS connection rate whenever a GPRS data service is requested; and

changing between a first GPRS connection mode and a second GPRS connection mode responsive to a comparison between the calculated connection rate and a predetermined connection rate.

2. The method of claim 1, wherein calculating the GPRS connection rate comprises:

counting the number of attempted GPRS connections and the number of successful GPRS connections whenever the GPRS data service is requested; and

dividing the number of successful GPRS connections by the number of attempted connections.

3. The method of claim 2, wherein the number of attempted GPRS connections is incremented upon each attempted connection, and the number of successful GPRS connections is incremented upon each successful connection.

4. The method of claim 1, wherein changing the GPRS connection mode comprises:

setting the GPRS connection mode to the first mode if the calculated connection rate is greater than the predetermined connection rate; and

setting the GPRS connection mode to the second mode if the calculated connection rate is not greater than the predetermined connection rate.

5. The method of claim 4, wherein changing further comprises initializing the number of attempted connections and initializing the number of successful connections if the GPRS connection mode was changed.

6. The terminal of claim 4, wherein the first connection mode is to connect with the network only when needed, and the second connection mode is to always remain connected with the network.

7. A method for changing a GPRS mobile terminal connection mode when the connection mode is ‘

when needed, the method comprising;

requesting a session connection for transferring data with the GPRS network;

counting each attempted GPRS connection;

counting each successful GPRS connection;

calculating a GPRS connection rate by dividing the number of attempted GPRS connections into the number of successful GPRS connections; and

maintaining the ‘

when needed’

connection mode if the calculated connection rate is greater than a predetermined connection rate, else changing the GPRS connection mode to ‘

always on’ and

initializing the number of attempted GPRS connections and the number of successful GPRS connections.

8. A method for changing a GPRS mobile terminal connection mode when the connection mode is ‘

always on, the method comprising;

requesting a session connection for transferring data with the GPRS network;

counting each attempted GPRS connections;

counting each successful GPRS connections;

calculating a GPRS connection rate by dividing the number of attempted GPRS connections into the number of successful GPRS connections;

maintaining the ‘

always on connection mode if the calculated connection rate is not greater than the predetermined connection rate, else changing the connection mode to ‘

when needed mode’ and

initializing the number of attempted GPRS connections and the number of successful GPRS connections.

9. A mobile terminal for communicating with a packet switched data service network, the terminal comprising:

a transceiver for establishing a connection with the packet switched data service network, wherein the transceiver exchanges data with the network; and

a processor coupled with the transceiver for determining a connection mode with the packet switched data service network and for establishing the connection with the network, wherein the processor calculates a connection rate and determines the connection mode responsive to the connection rate.

10. The terminal of claim 9, wherein the processor counts the number of attempted connections, counts the number of successful connections, and divides the number of successful connections by the number of attempted connections thereby calculating the connection rate.

11. The terminal of claim 10, wherein the terminal establishes the network connection using a first connection mode, wherein subsequent network connections are established using the first connection mode if the connection rate is favorable or a second connection mode when the connection rate is not favorable.

12. The terminal of claim 11, wherein the number of attempted connections and the number of successful connections are initialized when changing from the first connection mode to the second connection mode, or from the second connection mode to the first connection mode.

13. The terminal of claim 11, wherein the first connection mode is to connect with the network only when needed, and the second connection mode is to always remain connected with the network.

14. The terminal of claim 11, wherein the connection rate is favorable when it is greater than a predetermined connection rate, and the connection rate is not favorable when it is not greater that the predetermined connection rate.

15. The terminal of claim 9, wherein the packet switched data service is a General Packet Radio Service.
