    摘要： A first communications device communicates with a second communications device by means of a communications network. The first communications device receives information from the communications network, wherein the information comprises a network load value and a mean delay time value. The first communications device ascertains whether the network load value satisfies a predetermined relationship with respect to a threshold load value and if the predetermined relationship is satisfied then it communicates a data packet over the network at a designated time that is ascertained by ascertaining one of a number of different wait time values, wherein the ascertained wait time value has a mathematical expectation equal to the mean delay time value. The first communication device then waits an amount of time corresponding to the ascertained wait time, without attempting to communicate the data packet over the communications network during the time in which the first communications device is waiting.

    摘要： A method is disclosed for enabling device-to-device, D2D, communication when a communicating device is out of public land mobile network, PLMN, coverage for a first radio access technology, RAT. The method comprises scanning a carrier associated with a carrier predetermined for D2D communication for any signals, and if the scanning determines that D2D communication is present on the carrier, initiating out-of-coverage D2D communication, or if the scanning cannot determine that D2D communication is present on the carrier, determining a signal strength of other signals on the carrier and if the signal strength is below a threshold initiating out-of-coverage D2D communication. Alternatively, the method comprises scanning a carrier for at least a second RAT, and if a second RAT is detected, determining a PLMN of the detected RAT and accessing data on the determined PLMN about out-of-coverage D2D permissions, and if out-of-coverage D2D communication is permitted in the determined PLMN initiating out-of-coverage D2D communication. A communication device and computer program accordingly are also disclosed.

    摘要： Methods and arrangements for reporting of measurement information from a user equipment to a receiving entity via a network node comprised in a wireless communication system are disclosed. The embodiments relate to measurement logging function and immediate reporting function called Minimizing Drive Tests (MDT). The problem of reporting measurements in another RAT than in the RAT in which the measurements were collected in is addressed by a solution where a UE includes the measurement information collected in a first RAT in a message which is sent 36 to a network node in a second RAT. The network node then forwards 37 the message to a receiving entity without having to decode the actual content of the measurement log. This is done by introducing the receiving entity's IP address and/or similar addressing information in an address field in the message and using a container structure where the actual measurement log as reported by the UE is placed. The container need not be understandable by the network node and could be of a message format used in the RAT where the UE collected the measurement log. Thus, there is no need to reformat the measurement results.

    摘要： In one aspect, a network node determines there is a loss of user context information for one or more user equipments and signals to radio base stations connected to the network node to notify the one or more user equipments of the loss of user context information in broadcast system information. A radio base station transmits an information element indicating the loss of user context information in broadcast system information. A user equipment receives the information element in broadcast system information and detaches and reattaches to the network node upon a determination that the network node indicated by the information element matches a network node in registration information stored at the user equipment.
