Abstract: In one aspect of this disclosure, a transceiver obtains and transmits a CSI status indicator. In one example, the CSI status indicator indicates that previously reported CSI is outdated and/or that a new CSI report is available at the transceiver. In some embodiments, the transceiver generates or transmits the CSI status indicator according to a particular configuration, which may be set by a supporting wireless communication network. The configuration may include criteria on when to transmit the CSI status indicator, such as configuration criteria indicating that the transceiver should transmit the CSI status indicator responsive to completing its determination of a full-dimension beamforming matrix to be used for controlling beamforming towards the transceiver. The transceiver comprises, for example, a wireless device operating within a wireless communication network and the CSI status indicator corresponds to the status of downlink CSI.

Abstract: In a communication system including mobile terminals and different wireless networks the mobile terminals can estimate the speed with which the mobile terminals move and communicate estimated values of the speed to a selection function (17) selecting one of the wireless networks communicating information from and to the respective mobile terminal. In the estimating, first estimated speeds and/or positions of a mobile terminal are determined (11) particularly for each of the wireless networks, from the communication with the particular wireless network. Then the estimated values are by special interfaces (11) input to a different speed estimation function (15) in which a combined value of the speed of the mobile terminal is calculated, according to a speed estimation algorithm and is input to the selection function. In this speed estimation also a recommended one of the wireless networks can be determined.

Abstract: An IPTV group profile is dynamically generated based on individual IPTV user profiles, whenever a user joins or leaves a shared IPTV session at an IPTV Terminal Function (ITF). The IPTV group profile may be implemented as a modification to the IPTV user profile of each user. In one embodiment, a “group” branch includes the additional access privileges and/or restrictions from the IPTV user profiles of other group members. The modified IPTV user profiles of users in the group are placed on a network entity such as an XDM Server (XDMS), to which the ITF subscribes via XCAP. As users join or leave a shared IPTV session at an ITF, the IPTV-AS updates the IPTV user profiles on the XDMS, which notifies the ITF of the changes. Each user's IPTV user profile at the ITF thus reflects group access privileges, preferences and restrictions for the duration of the shared IPTV session.

Abstract: An apparatus and method for providing Single Sign-On services to a user when accessing a selected Service Provider from a plurality of Service Providers. An Authentication Provider authenticates the user at with a user-identity, provides the user with a token as proof of the authentication, and assigns a temporary alias-identity to the user for use when the user accesses the selected Service Provider. The Authentication Provider and the selected Service Provider link the assigned alias-identity and the user-identity to identify the user at respective sites. The user accesses the selected Service Provider by presenting the token along with a local user-identity valid for the selected Service Provider. When the user attempts a subsequent access at the selected Service Provider, the user is identified by the shared alias-identity, if the user allowed permanent linking. If the user did not allow permanent linking, the process is repeated for each subsequent access.
