System and methods for dynamically configurig cell search window for pilot acquisition

An apparatus for selecting cell search window for a mobile device, the apparatus comprising:

• a memory for storing search window parameters for a plurality of radio access network (RAN) cells;
• a receiver operable to receive pilot signals from a plurality of RAN cells;
• and
• a processor coupled to the memory and to the receiver and operable to:
• acquire a first RAN cell using a first search window associated with the first RAN cell;
• determine to acquire a second RAN cell operating at least in part in the same region as the first RAN cell;
• select a second search window for acquiring the second RAN cell, wherein the second search window is different from the first search window;
• and
• acquire the second RAN cell using the selected second search window.

A computer program product for selecting cell search window for a mobile device, the product comprising a non-transitory computer-readable medium comprising:

• a first set of codes for acquiring by the mobile device a first radio access network (RAN) cell using a first search window associated with the first RAN cell;
• a second set of codes for determining to acquire a second RAN cell operating at least in part in the same region as the first RAN cell;
• a third set of codes for selecting a second search window for acquiring the second RAN cell, wherein the second search window is different from the first search window;
• and
• a fourth set of codes for acquiring the second RAN cell using the selected second search window.

An apparatus for establishing connection with a radio access network, the apparatus comprising:

• means for acquiring by the mobile device a first radio access network (RAN) cell using a first search window associated with the first RAN cell;
• means for determining to acquire a second RAN cell operating at least in part in the same region as the first RAN cell;
• means for selecting a second search window for acquiring the second RAN cell, wherein the second search window is different from the first search window;
• and
• means for acquiring the second RAN cell using the selected second search window.

A wireless communication device configured to communicate in a wireless communication network, the device comprising:

• a communications interface configured to connect to a first network using a first search window associated with the first network;
• a processor configured to determine to connect to a second network that at least in part overlaps with the first network;
• the processor configured to select a second search window for acquiring the second network;
• and
• the communications interface configured to connect to the second network using the second search window.
