The embodiments herein relate to a method in a wireless device () for enabling trusted communication between a wireless device entity () and a second network node () via a first network node (). The wireless device () and the first network node () are adapted to communicate using a secure communication channel. The wireless device () transmits a message to the first network node () using the secure communication channel. The message comprises information indicating that the wireless device entity () is comprised in a trusted zone of the wireless device (). The trusted zone is at least partly trusted by the first network node ().

Authentication of wireless device entity

Example embodiments presented herein are directed towards a wireless device and a Policy Control and Charging (PCC) based node, and methods therein, for managing an operating system and/or application behavior based on an indication of a network initiated policy and/or charge change. Thus, based on an indication of such a change, an applications behavior may be modified accordingly. Examples of such modification comprise initiating or restriction a communication with the network. Examples of a network initiated policy and/or charge change comprise a start or end to a non-metered connection or a change in a QoS level.

Wireless device management based on a network initiated policy and/or charge change

In a radio system a network node is provided to be operatively connected to a set of radio base stations of the radio network and to retrieving a neighbor list from each radio base station in said set of radio base stations. Based on said list of neighbors it is determined if a pair of radio base stations lack a connection between them, and upon determining that a connection between two radio base stations is lacking a connection between said pair of radio base stations is set up.

Methods and devices for managing a cellular radio network

The present invention relates to a device and method for simulating a radio channel with a defined characteristic between at least one antenna port () of a first device (), and a second device () in a test environment. The device comprises a first antenna () adapted to transmit signals, and arranged to provide a first radio channel () between the first antenna () and the second device () and, a second antenna () adapted to transmit signals, and arranged to provide a second radio channel () between the second antenna () and the second device (). A characteristic of the second radio channel () is dissimilar to a characteristic of the first radio channel (). The device further comprises a multiport circuit () arranged to connect the at least one antenna port () of the first device () with the first and second antennas (), and adapted to split a signal received from the at least one antenna port () into at least two split signals, and to forward the at least two split signals to the first and second antennarespectively. The device also comprises a modifying circuit () adapted to modify an amplitude relation between the at least two split signals, thereby simulating a radio channel between the at least one antenna port () and the second device () with a characteristic which is a combination of the characteristic of the second radio channel () and the characteristic of the first radio channel () in a relation corresponding to the modified amplitude relation.

Method and device in over-the-air test environment

The present invention relates to a device and method for simulating a radio channel with a defined characteristic between at least one antenna port () of a first device (), and a second device () in a test environment. The device comprises a first antenna () adapted to receive signals, and arranged to provide a first radio channel () between the first antenna () and the second device () and, a second antenna () adapted to receive signals, and arranged to provide a second radio channel () between the second antenna () and the second device (). A characteristic of the second radio channel () is dissimilar to a characteristic of the first radio channel (). The device further comprises a modifying circuit () adapted to modify an amplitude relation between the received signals, and a multiport circuit () arranged to connect the first and second antennas () with the at least one antenna port (). The multiport circuit () is also adapted to combine the modified signals, and to forward the combined signals to the at least one antenna port (), thereby simulating a radio channel between the at least one antenna port () and the second device () with a characteristic which is a combination of the characteristic of the second radio channel () and the characteristic of the first radio channel () in a relation corresponding to the modified amplitude relation.

A method, system, and apparatus enables lower priority (e.g., access response) messages to be transmitted instead of higher priority (e.g., paging) messages when the lower priority messages become too backlogged in an environment in which the two types of messages share a given capacity. In other words, when an overload situation is detected, the shared capacity is regulated by ensuring that the lower priority messages have at least some bandwidth. For example, if (i) the lower priority messages reach a predetermined number or (ii) a particular lower priority message has been waiting a predetermined period of time, then at least a portion of the higher priority messages are diverted (e.g., delayed or deleted). In one embodiment, the higher priority messages that are initially diverted are a lowest priority subset of the higher priority messages. In another embodiment, a highest priority subset of the lower priority messages are transmitted first as capacity is made available.

Signal prioritization in a communications system

A method is presented for address resolution mapping in a wireless multihop communication network wherein the network is built up by client devices and/or infrastructure devices, network traffic is based on using ARP forwarding and rebroadcasting to locate devices in such a network architecture. The invention also includes devices for such a network and the complete communication system is described.
