Title: FIRST NETWORK NODE, SECOND NETWORK NODE, WIRELESS DEVICE AND METHODS THEREIN FOR HANDLING BROADCAST INFORMATION
Abstract:
A method for handling broadcast information is described. A first network node (111) operating in a wireless communications network (100) determines (403) one or more decryption keys (K1, K2, K3) to be provided to a wireless device (131) in the wireless communications network (100). The decryption keys enable the wireless device (131) to decrypt information to be broadcasted by a second network node (112) in the wireless communications network (100). The information comprises a plurality of subsets of positioning information. Each of the subsets is to be, or is, encrypted with a different encryption key based on a respective type of subscription for wireless devices (131, 132, 133) in the wireless communications network (100). The determined decryption keys are based on at least one type of subscription of the wireless device (131). The first network node (111) then initiates (404) providing the determined to the wireless device (131).
