Limited service state control

摘要

Limited service state controller (30) for controlling activity of a mobile device (1) when the mobile device is in a limited service state, in which the mobile device camps on an acceptable serving cell of a cellular telecommunication network, the limited service state controller being configured to: get mobile device state information indicating that the mobile device is in the limited service state, get radio environment parameters related to a radio environment of the mobile device, and determine activity parameters to be set in the mobile device based on the mobile device state information and/or the radio environment parameters, for limiting the activity of the mobile device compared to the activity to be done when the mobile device is in a normal service state, while enabling access to an emergency service allowing to make an emergency call.

1. A limited service state controller in a mobile device and for controlling activity of the mobile device when the mobile device is in a limited service state, in which the mobile device camps on an acceptable serving cell of a cellular telecommunications network and is able to make an emergency call, the limited service state controller being configured to:
get mobile device state information indicating that the mobile device is in the limited service state, get radio environment parameters related to a radio environment of the mobile device which is in the limited service state, determine activity parameters to be set in the mobile device based on the mobile device state information which indicates the mobile device is in the limited service state and based on the radio environment parameters, and set the determined activity parameters in the mobile device by the limited service state controller, wherein the activity parameters limit the activity of the mobile device in the limited service state to reduce power consumption of the mobile device compared to the activity of the mobile device allowed in a normal service state, wherein the radio environment parameters comprise two or more of the following: a parameter related to a number of neighbor cells, a parameter related to a speed of mobile device and a parameter related to a geographical type of environment, and wherein the activity parameters comprise at least one of the following: serving parameters, neighbour cells monitoring parameters, paging filtering parameters, and system information filtering parameters.
