Method and apparatus for providing access for a limited set of mobile stations to a restricted local access point
First Claim
1. Method of providing access for a limited registered set of mobile stations to a restricted local access point in a wireless network, comprising the steps of:
- attracting mobile stations in an area covered by the restricted local access point, for each mobile station that is attracted;
determining, by the restricted local access point, whether the mobile station belongs to the limited registered set,based on the determination that the mobile station belongs to the limited registered set, allowing the mobile station access to the restricted local access point, andbased on the determination that the mobile station does not belong to the limited registered set, rejecting access for the mobile station to the restricted local access point;
wherein the step of attracting comprises sending by the restricted local access point a minimum link quality value level to all mobile stations in the covered area, where a link quality value that is determined for the restricted local access point by one of the mobile stations has to exceed the minimum link quality value level for the one mobile station to be attracted; and
,wherein the step of attracting further comprises sending by the restricted local access point, to all mobile stations in the covered area, a network identity associated with the restricted local access point and other restricted local access points in the wireless network, wherein the network identity is different than a second identity of unrestricted global access points in the wireless network.

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.

15. Control device for a restricted local access point for provision in a wireless network, said restricted local access point being implemented by a device comprising:
-
a radio communication unit, and, said control device being arranged to; order the radio communication unit to attract mobile stations in an area covered by the restricted local access point, and for each mobile station that is attracted; determine whether the mobile station belongs to a limited registered set of mobile stations, based on the determination that the mobile station belongs to the limited registered set of mobile stations, allow the mobile station access to the restricted local access point, and based on the determination that the mobile station does not belong to the limited registered set of mobile stations, reject access for the mobile station to the restricted local access point; wherein the control device is further arranged to provide the radio communication unit with a minimum link quality value level to be sent all mobile stations in the covered area for attracting them, where a link quality value that is determined for the restricted local access point by one of the mobile stations has to exceed the minimum link quality value level for the one mobile station to be attracted; and
,wherein the control device further arranged to attract mobile stations by providing the radio communication unit with a network identity to be sent to all mobile stations in the covered area, wherein the network identity is associated with the restricted local access point and other restricted local access points in the wireless network, and wherein the network identity is different than a second identity of unrestricted global access points in the wireless network. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. Wireless network comprising:
-
a number of unrestricted global access points, and at least one device implementing a restricted local access point that comprises; a radio communication unit, and a control device for the restricted local access point being arranged to; attract mobile stations in an area covered by the restricted local access point, for each mobile station that is attracted; determine whether the mobile station belongs to a limited registered set of mobile stations, based on the determination that the mobile station belongs to the limited registered set of mobile stations, allow the mobile station access to the restricted local access point, and based on the determination that the mobile station does not belong to the limited registered set of mobile stations, reject access for the mobile station to the restricted local access point; wherein the control device is further arranged to provide the radio communication unit with a minimum link quality value level to be sent all mobile stations in the covered area for attracting them, where a link quality value that is determined for the restricted local access point by one of the mobile stations has to exceed the minimum link quality value level for the one mobile station to be attracted; and
,wherein the control device is further arranged to attract mobile stations by providing the radio communication unit with a network identity to be sent to all mobile stations in the covered area, wherein the network identity is associated with the restricted local access point and other restricted local access points in the wireless network, and wherein the network identity is different than a second identity of unrestricted global access points in the wireless network.
