摘要:
It is presented a method for detecting potential displacement of a wireless transceiver connected to a machine-to-machine device. The method comprises the steps, executed in a displacement detection server, of: receiving an updated radio environment message from the wireless transceiver, the radio environment message comprising updated radio characteristics of at least two radio cells, the updated characteristics being measured by the wireless transceiver; determining whether the updated radio characteristics differ significantly from previous radio characteristics of a previous radio environment message from the wireless transceiver; and when it is determined that radio characteristics differ significantly, sending a displacement indication message to a device management server, the displacement indication message indicating potential displacement of the wireless transceiver. Corresponding displacement detection server, host device, computer program and computer program product are also presented.

A method in a subscriber identity module, a subscriber identity module, a method in a user device and a user device for provisioning of network information is provided. Moreover, a method in a first network node and a first network node for managing network information is provided. The first network node receives a request for the network information, wherein the request comprises information about capabilities of the user device. Next, the first network node generates network information according to a format selected according to the capabilities of the user device. The network information is received by the user device. Next, the user device provisions the network information into the subscriber identity module.

A Proxy Unit is connectable to a communication network and is arranged to enable IP Communication with a Machine to Machine Unit. The Proxy Unit receives and stores in a session data base a first IP address a device identifier and a unique ID of the Machine to Machine Unit. The Proxy Unit then receives from a Machine to Machine application a message destined to the Machine to Machine Unit and comprising the unique ID of the Machine to Machine Unit. The Proxy Unit finds the associated device identifier and the first IP address in the session data base, using the received unique ID. If the Proxy Unit detects no active session for the Machine to Machine Unit, it uses the device identifier to send a wake up message to the Machine to Machine Unit for enabling IP communication.

A method and apparatus for obtaining a real time media stream provided as a plurality of media fragments from a plurality of remote nodes in a communications network. A first series of media fragments satisfying a first selection criterion is requested from a first remote node and a further series of media fragments satisfying a further different selection criterion is requested from at least one further remote node. When combined, the first series of fragments and the further series of fragments provide the complete media stream.
