Abstract

The invention concerns methods, a device and computer program products for simplifying handover back to a restricted local access point from an unrestricted global access point as well as to a device implementing a restricted local access point for provision in a wireless network and a wireless network. In the network a restricted local access point hands over a mobile station to an unrestricted global access point and provides data enabling the restricted local access point to be identified as a candidate access point. A device for simplifying handover back determines that the restricted local access point is a candidate for further handover based on this data and informs the mobile station about the restricted local access point via the unrestricted glob access point. Thereby hand over may be considered also to the restricted local access point in addition to other surrounding access points.
