Patent ID: 8903372

Claim:
A method of performing neighboring cell signal measurements in a mobile device having a first service stack and a second service stack sharing a single transceiver channel, comprising: receiving, in the first service stack, a request for neighboring cell signal measurement data from the second service stack, wherein the request identifies neighboring cells to be measured; measuring signal strength of neighboring cells via the first service stack to generate the requested neighboring cell signal measurement data in the first service stack by: identifying common neighbor cells between the first service stack and the second service stack; and measuring signal strength of any unique identified neighboring cells to be measured and any neighbor cells common among the first service stack and the second service stack only once to generate the requested neighboring cell signal measurement data in the first service stack; and providing the requested neighboring cell signal measurement data from the first service stack to the second service stack, wherein the first service stack and the second service stack are each associated with a single subscription served by different radio access networks and by one core network.
