In a communication apparatus on a network where communication apparatuses perform direct communication with each other, a network management apparatus for managing the network based on message information transmitted and received on the network is determined. When the communication apparatus itself is determined as the network management apparatus, the apparatus collects information indicating device capabilities from other communication apparatuses. On the other hand, the communication apparatus receives information indicating device capabilities from another communication apparatus when the other communication apparatus is determined as the network management apparatus.

A system and method for wireless synchronization on a network are disclosed. In one embodiment, the wireless device includes a wireless transceiver and processing circuitry. The wireless transceiver wirelessly receives synchronization information including a superframe from a first wireless, reader device, and wirelessly transmits the synchronization information to a second wireless, reader device and a portable wireless device, and to wirelessly detect a presence of a portable wireless device. The processing circuitry communicates synchronization information to the second wireless, reader device and portable wireless device. The superframe is used to synchronize a wireless data exchange between the third wireless, reader device and the portable wireless device.

A system includes a common display, a display computer to run collaboration software connected to the common display that drives the common display, the display computer being on a first network, a first mobile device to run a sharing application and a streaming application, the first mobile device being on a second network, separate from the first network, the streaming application to convert a display of the mobile device into stream data, a control channel between the mobile device and the display computer, and a stream channel between the display computer and the mobile device. The mobile device sends stream data directly to the display computer, wherein the display computer is to display the stream data on the common display. The stream channel may be directly between the mobile device and the display computer or may be over a relay server.

Features are described for efficiently and accurately identifying a user of an electronic device with limited user interaction. The features include receiving a mobile device identifier from the mobile device. The features include transmitting the mobile device identifier to a service provider associated with the mobile device. The features include receiving information identifying the user from the service provider. The features include identifying a set of candidates associated with at least a portion of the information. The features include generating a metric for the candidates included in the set of candidates. An individual metric indicates a degree of relatedness between a value for the user for the at least one data field and a value for a candidate for the at least one data field. The features include identifying the user as a specific candidate included in the set of candidates based on the metric corresponding to a threshold.

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).
