Abstract

An apparatus is provided to include a detector. The detector can detect that an interfering communications connection to a received satellite system signal in a mobile terminal is to be established by the mobile terminal. The apparatus include a processor that can prevent interference to the received satellite system signal due to the interfering communications connection by controlling uplink resource allocation of the mobile terminal based on the detection.
