A connection setup method of a wireless communication device adapted to be operated in a heterogeneous cellular communication network is disclosed. The heterogeneous cellular communication network comprises at least a first cell and a second cell, respectively associated with a first cell layer and a second cell layer of the heterogeneous cellular communication network. The wireless communication device is adapted to use a serving cell associated with the first cell layer or the second cell layer when the wireless communication device is in an active mode, and to use a camping cell associated with the first cell layer when the wireless communication device is in an idle mode. The method comprises detecting, when the wireless communication device is in the active mode and uses the second cell as the serving cell, that the serving cell is associated with the second cell layer. In response to detecting an upcoming transfer to the idle mode, the method comprises storing connection setup parameters of the second cell and transferring to the idle mode, wherein transferring comprises selecting the first cell as the camping cell. The method also comprises, when the wireless communication device is in the idle mode, detecting an upcoming transfer to the active mode and transferring to the active mode, wherein transferring comprises setting up a connection to a cell of the heterogeneous cellular communication network based on the stored connection setup parameters of the second cell. Corresponding computer program product, arrangement and wireless communication device are also disclosed. |
