Abstract: A method and apparatus for allocating an identifier to a terminal in a communications network. A core network controlling node, such as a Mobility Management Entity (MME) receives an International Mobile Subscriber Identity (IMSI) and an International Mobile Equipment Identity (IMEI) from the terminal. Subscription information is determined using both the IMSI and the IMEI. A temporary identifier that can be used to identify the terminal is then allocated to the subscription information.

Abstract: The present invention discloses a method in a wireless access network node for controlling a UE. The UE comprises at least two transmit antennas, and is capable of uplink transmit diversity. There is an antenna weight associated with each transmit antenna. First, the wireless access network node determines that the antenna weights of the user equipment may be controlled. Then, it creates a control signal that comprises control information and transmits it to the user equipment. The control information controls a UE autonomous selection of the antenna weights in the UE.

Abstract: A relay node (800) reports its output power capability to a donor base station or other network node separately for the relay node's backhaul and access links, which may have different maximum output power. A corresponding network node (900), such as a donor base station, an Operations & Maintenance node, an Operational Support Systems node, a Self-Organizing Network node, is configured to request the relay node (800) to report its backhaul link and access link output power class capabilities or maximum output powers or rated output powers to the network node (900), and then to receive the reported capabilities in response. The report may specify a per-antenna transmit power capability; this may be specifically requested in some cases. The received relay node power-class capability information for the backhaul and access links is then used for one or several network management functions, such as radio resources management or network planning and dimensioning.

Abstract: The present invention relates to methods and arrangements for locating services in a structured peer-to-peer distributed hash table, DHT, based, overlay communication network (310). The invention comprises two inter-related methods and nodes. The first method is used by a service node (321) to “advertise” to the overlay network (310) that it is providing a particular service (S1). This is done by distributing instances (351,352,353) of a service object (O1) that are stored in different nodes (331,332,333) in the overlay network (310) and where the instances (351,352,353) comprise an address to the service node (321). The other method is to locate at least one of these instances (351,352,353) with a predetermined probability and with a predetermined number of location request messages (390) from a user node (311) wishing to use the particular service (S1).
