Patent ID: 8892095

Claim:
A method for operating a stationary terminal device in a cellular mobile communication network that has a plurality of radio access network cells, the method comprising: the terminal device detecting that it is being or is about to be operated in a non-connected state, the terminal device detecting whether or not at least one radio access network cell of a mobile communication network fulfils a first suitable-cell-requirement, the terminal device selecting one of those radio access network cells that fulfil a first suitable-cell-requirement as a home cell for operation of the terminal device as a stationary terminal device in the non-connected state and associating the terminal device to the home cell while operated as stationary terminal device by signal exchange with a base station allocated to the home cell, the terminal device subsequently detecting whether or not the selected home cell fulfils a second suitable-cell-requirement that in comparison with the first suitable-cell-requirement is biased in favour of the terminal device remaining associated with the selected home cell and against selecting another radio access network cell as the new home cell; and the terminal device not initiating a change from the selected home cell to another radio access network cell as a new home cell during the non-connected state for as long as during the non-connected state the selected home cell fulfils the second suitable-cell requirement.
