Abstract
Methods and devices for enabling improved cell reselection procedures on a wireless communication device with a first SIM is camped on a serving cell of a first network may include receiving a list of neighbor cells from system information that is broadcast in the serving cell, and performing signal measurements associated with the listed neighbor cells and the serving cell, and, based on the signal measurements, identifying neighbor cells that satisfy selection criteria. The wireless device may calculate ranking criteria for the serving cell and the identified neighbor cells, and determine whether an inter-frequency neighbor cell has a highest ranking criteria among all of the ranked cells. Upon determining that an intra-frequency neighbor cell has the highest ranking criteria, the wireless device may start a reselection timer and also start decoding the system information that is being broadcast in the intra-frequency neighbor cell that has the highest ranking criteria.
