Abstract

A wireless device may receive a BA-list from a wireless service provider. Before removing any cell frequencies already stored in the wireless device, the wireless device may determine if the BA-list is complete. If the BA-list is not complete, the cell frequencies already stored in the wireless device may be retained, and the cell frequencies received in the BA-list may be added to the storage. However, if the BA-list is complete, the cell frequencies already stored in the wireless device may be removed if they are not in the BA-list.

Claims (40)

1. A method, comprising:

storing in storage a first frequency associated with a first cell;

receiving a second frequency associated with a second cell;

determining that one or more frequencies associated with a list of frequencies is not stored in the storage; and

maintaining the first frequency associated with the first cell in the storage after receiving the second frequency associated with the second cell, the maintaining act executed based on the determining that one or more frequencies associated with a list of frequencies is not stored in the storage.

2. The method according to claim 1 , wherein the second frequency associated with the second cell is received in a slow associated control channel (SACCH) message.

3. The method according to claim 1 , further comprising monitoring an attribute of the first frequency associated with the first cell after receiving the second frequency associated with the second cell.

4. The method according to claim 3 , wherein the attribute is a signal strength of the first frequency.

5. The method according to claim 1 , further comprising:

packaging the second frequency with a flag; and

sending the packaged second frequency and flag to an module administering storage of frequencies associated with cells.

6. The method according to claim 5 , wherein the flag is (1) to instruct the module administering storage of frequencies to store the second frequency, (2) to instruct the entity administering storage of frequencies to store the second frequency and delete any currently stored frequencies, or (3) to instruct the entity administering storage of frequencies that no action is required.

7. The method according to claim 5 , wherein the flag has at least three togglable states.

8. The method according to claim 1 , wherein the storing act stores the first frequency associated with the first cell in a list, and further comprising storing the second frequency associated with the second cell in the list; monitoring a signal strength associated with the second frequency associated with the second cell; and reporting the signal strength associated with the second frequency associated with the second cell to a network entity.

9. A method, comprising:

receiving a first Broadcast Control Channel (BCCH) Allocation list (BA-list) including at least one frequency associated with a cell;

resolving that the BA-list is incomplete;

storing in storage the at least one frequency associated with the cell in a list allocated to store frequencies;

maintaining any other frequencies in the list after the storing of the at least one frequency associated with the cell in the list; and

receiving a network message that indicates that the BA-list is complete.

10. The method according to claim 9 , wherein the list allocated to store frequencies includes at least one frequency associated with another cell.

11. The method according to claim 9 , further comprising:

receiving a second BA-list including at least one frequency associated with another cell;

resolving that the BA-list is complete; and

storing the at least one frequency associated with the another cell in the list allocated to store frequencies.

12. The method according to claim 11 , further comprising removing any cells stored in the list allocated to store frequencies that are not associated with the complete BA-list.

13. The method according to claim 9 , further comprising packaging the at least one frequency associated with the cell with a flag, the flag toggled to a state that indicates that the BA-list is incomplete.

14. An apparatus, comprising:

a processor coupled to a storage, the processor enabled to execute computer-executable instructions stored in the storage, the computer-executable instructions including:

a radio resource layer (RR layer) module to receive at least one frequency associated with a cell and generate a flag to be associated with the at least one frequency associated with the cell; and

a layer module to receive the at least one frequency associated with the cell and the flag associated with the at least one frequency.

15. The apparatus according to claim 14 , wherein the flag indicates that a BA-list is incomplete.

16. The apparatus according to claim 14 , wherein the layer module is a layer 1 module, the layer 1 module further to store the at least one frequency associated with the cell in a list that contains at least one additional frequency associated with another cell.

17. The apparatus according to claim 16 , wherein the layer 1 module is further to initiate measuring a signal strength of the at least one frequency associated with the cell, and send the signal strength of the at least one frequency and a signal strength of at least one additional frequency to the RR layer.

18. The apparatus according to claim 17 , wherein the RR layer is to further send the signal strength of the at least one frequency to a network entity and discard the signal strength of the at least one additional frequency.

19. A method, comprising:

receiving from a first layer module being associated with computer executable instructions stored in a storage measurement information related to a first cell and second cell; and

selecting measurement information from the measurement information related to a first cell and second cell to send to a network entity, the selected measurement information based on a current Broadcast Control Channel (BCCH) Allocation list (BA-list).

20. The method according to claim 19 , wherein the selecting act is performed by a radio resource layer (RR layer) module stored in the storage.

21. The method according to claim 19 , wherein the selecting at selects the measurement information related to the first cell, the first cell being listed in the BA-list.
