Method and Apparatus for Securing a Connection in a Communications Network A method of operating a user equipment (UE) using a Generic Bootstrapping Architecture (GBA) is provided. The method includes establishing a shared secret between the UE and a Network Application Function (NAF). An authentication request is sent to a Bootstrapping Server Function (BSF) by the UE. An original parameter intended for a key derivation function and a bootstrapping transaction identifier is received from the BSF. An application request, including the bootstrapping transaction identifier, is sent by the UE to the NAF. A modified parameter is derived by the UE from the secret and the original parameter intended for the key derivation function. A cryptographic key is determined using said modified parameter in place of or in addition to the original parameter in the key derivation function, and communications with the NAF are secured using the key.

This disclosure relates to methods and arrangements for positioning of a communication device () in a communication system. Based on received radio channel information from a positioning server (), positioning nodes (-) identify (S-, S-) a radio signal from said communication device, measure (S-, S-, S-) the strength of said received signal and sends (S-, S-, S-) signal strength information and position information of the positioning nodes to said positioning server. The positioning server then determines (S-, S-) the position of the communication devices based on the received signal strength measurements and the position information of the positioning nodes. High accuracy in-door positioning of communication devices is achieved.

An object of the present invention is to provide an improved and simplified mechanism for assisting in antenna direction adjustment. The object is achieved by a method in a wireless communication devicefor assisting in direction adjustment of a directional antenna. The wireless communication deviceis adapted to be connected to a wireless communication systemvia a directional antenna. The wireless communication systemcomprises a service node The method comprises the first step of establishinga radio connection to the wireless communication systemvia the directional antennaand the second step of sendinga request for antenna direction information to the service nodeand the third step of receivingthe requested antenna direction information from the service nodeand the fourth step of obtainingperformance measurement and the fifth step of sendingthe obtained performance measurement to the service nodeand the sixth step of receivingan indication of an antenna direction to be used from the service node
