First Claim
Patent Images
1. A method in a mobile station, the method comprising:
- establishing bi-directional communication between the mobile station and a serving base station;
determining that a radio link parameter of an intra-frequency neighbor base station of the serving base station is better than a first threshold;
determining that a radio link parameter of an inter-frequency neighbor base station is better than a second threshold; and
decoding a system information message of the inter-frequency neighbor base station only if the radio link parameter of the intra-frequency neighbor base station is better than the first threshold and the radio link parameter of the inter-frequency neighbor base station is better than the second threshold;
wherein the first threshold differs from the second threshold.

Abstract
A method (300) and apparatus (200) for radio link failure recovery is disclosed. The method may include detecting (320) the presence of an intra-frequency neighbor base station (145) of a serving base station (135). The method may include determining (330) that a radio link parameter of an inter-frequency neighbor base station is better than a threshold. The method may include acquiring (350) system information of the inter-frequency neighbor base station if the intra-frequency neighbor base station is present and if the radio link parameter of the inter-frequency neighbor base station is better than the threshold.
