Abstract

An exemplary system and method for determining handovers for a mobile device are disclosed. An exemplary system may generally include a handover server in communication with a communication network configured to support initiated communications from a mobile device. The handover server is configured to detect an initiated communication between the mobile device and a first communication link, determine a value for each of a plurality of factors associated with each of a plurality of available communication links, and assign a desired communication link to the mobile device from the plurality of available communication using a generally simultaneous assessment of the plurality of factors.

Claims (32)

1. A method, comprising:

detecting an initiated communication between a mobile device and a first communication link;

determining a value for each of a plurality of factors associated with each of a plurality of available communication links;

assigning a desired communication link from the plurality of available communication links based upon a generally simultaneous assessment of the plurality of factors;

classifying each of the factors as one of a positive factor and a negative factor;

establishing the factors as a positive factor when a maximum value associated with the factor increases a probability of selecting the communication link associated with the positive factor; and

establishing the factors as a negative factor when a maximum value associated with the factor decreases a probability of selecting the communication link associated with the negative factor.

2. The method of claim 1 , establishing selecting the desired communication link from the plurality of available communication links based upon the plurality of factors as determining a handover index for each of the available communication links, and establishing the handover index as a numerical comparison of the positive and negative factors for each of the communication links.

3. The method of claim 2 , establishing the numerical comparison as one of a ratio of the positive factors to the negative factors, and a ratio of the negative factors to the positive factors.

4. The method of claim 1 , further comprising:

normalizing the plurality of factors to create a plurality of normalized factors;

establishing the normalizing of the plurality of factors as scaling each of the plurality of factors between a minimum magnitude associated with each of the plurality of factors and a maximum magnitude associated with each of the plurality of factors; and

establishing determining the desired communication link as determining the desired communication link based upon at least the plurality of normalized factors.

5. The method of claim 1 , further comprising weighting each of the factors according to a predetermined relative importance of each of the factors.

6. The method of claim 1 , further comprising determining the plurality of available communication links.

7. The method of claim 1 , establishing the plurality of available communication links as having a predetermined link signal strength with the mobile device.

8. The method of claim 1 , further comprising receiving the signal transmission at the first communication link.

9. The method of claim 8 , further comprising receiving the signal transmission at the desired communication link.

10. The method of claim 1 , further comprising initiating a handover of the signal transmission from the first communication link to the desired communication link.

11. The method of claim 1 , establishing the initiated communication as a phone call.

12. A communication system, comprising:

a handover server storing a heuristic for determining handovers for a mobile device;

wherein the handover server is configured to detect an initiated communication between the mobile device and a first communication link, the handover server further configured to determine a value for each of a plurality of factors associated with each of a plurality of available communication links, the handover server further configured to assign a desired communication link to the mobile device from the plurality of available communication using a simultaneous assessment of the plurality of factors; and

wherein the handover server is configured to classify each of the factors as one of a positive factor and a negative factor, the handover server further configured to classify the factors as a positive factor when a maximum value associated with the factor increases a probability of selecting the communication link associated with the positive factor, and classify the factors as a negative factor when a maximum value associated with the factor decreases a probability of selecting the communication link associated with the negative factor.

13. The communication system of claim 12 , wherein the handover server is configured to select the desired communication link from the plurality of available communication links based upon a handover index for each of the available communication links, the handover index including a generally simultaneous numerical comparison of the positive and negative factors for each of the communication links.

14. The communication system of claim 12 , wherein the initiated communication is a phone call.

15. A system, comprising:

a handover server in communication with a communication network configured to support initiated communications from a mobile device;

wherein the handover server is configured to detect an initiated communication between the mobile device and a first communication link, the handover server further configured to determine a value for each of a plurality of factors associated with each of a plurality of available communication links, the handover server further configured to assign a desired communication link to the mobile device from the plurality of available communication using a simultaneous assessment of the plurality of factors; and

wherein the handover server is configured to classify each of the factors as one of a positive factor and a negative factor, the handover server further configured to classify the factors as a positive factor when a maximum value associated with the factor increases a probability of selecting the communication link associated with the positive factor, and classify the factors as a negative factor when a maximum value associated with the factor decreases a probability of selecting the communication link associated with the negative factor.

16. The system of claim 15 , wherein the handover server is configured to select the desired communication link from the plurality of available communication links based upon a handover index for each of the available communication links, the handover index including a generally simultaneous numerical comparison of the positive and negative factors for each of the communication links.

17. The system of claim 15 , wherein the initiated communication is a phone call, and the primary data line is a primary phone number.
