Patent ID: 8538415

Claim:
A method of initiating inter-frequency measurements within a mobile radio communications device within a pico/micro cell, said method comprising: inspecting by way of a network the load state of the pico/micro cell in which the mobile radio communications device is located; paging the mobile radio communications device with a Paging Type 1 message, which includes an inter-frequency measurement delay-allowed field, to indicate whether or not the inter-frequency measurements should be performed in the mobile radio communications device, before responding to the Paging Type 1 message; conducting the inter-frequency measurements in the mobile radio communications device after checking the inter-frequency measurement delay-allowed field of the Paging Type 1 message, if the inter-frequency measurement delay-allowed field is indicative of an execution of the inter-frequency measurements, before responding to the Paging Type 1 message; and transmitting a result of the inter-frequency measurements on the pico/micro cells from the mobile radio communications device to the network through a Random Access Channel (RACH) channel.
