Abstract: Method and communication network node for enabling a radio base station to adjust a Radio Access Network, RAN, capability within a RAN, such as handover or scheduling, dependent on a data transport characteristics of a backhaul network, such as data transfer rate, network delay and bandwidth. The RAN and the backhaul network are parts of a telecommunication network, and the first communication network node is arranged in the telecommunication network to communicate data between the RAN and a core network node in the telecommunication network. By acquiring knowledge of variations of transport characteristics in backhaul networks, RAN capabilities may be adjusted, e.g. by performing handover of UEs to other radio base stations which have better backhaul transport characteristics. Thereby, user experience for the users of the UE may be increased. In addition, an operator of the communication network may make better use of installed transport capacity.

Abstract: There is described a method for optimizing the distribution of data objects between caches in a cache domain of a resource limited network. User requests for data objects are received at caches in the cache domain. A notification is sent from each cache at which a request is received to a cache manager. The notification reports the user request and identifies the requested data object. At the cache manager, object information including the request frequency of each requested data object and the locations of the caches at which the requests were received is collated and stored. At the cache manager, objects for distribution within the cache domain are identified on the basis of the object information. Instructions are sent from the cache manager to the caches to distribute data objects stored in those caches between themselves.

Abstract: The embodiments herein relates to a method in a first network node for handling operation mode of a base station in a communications network. The communications network comprises a transport network. The first network node activates a Remote Unit-Main Unit, RU-MU, operation mode in the base station when data traffic load in the transport network is below a first threshold. The first network node activates a regular operation mode in the base station when the data traffic load in the transport network is above a second threshold.

The first base station (201) comprises a transport network transmission equipment (205) and the transport network transmission equipment (205) is a part of a transport network. When the first base station (201) is in a sleep mode, the first network node (215) determines (306, 801) that the transport network transmission equipment (205) should be bypassed by activating a relay (209) comprised in the first base station (201) such that data traffic from a second network node (217) is transmitted via the relay (209) to a third network node (220).

Abstract: The following invention relates to methods and nodes for performing Lawful Intercept, LI, when service related content is stored in a Radio Access Network, RAN or a wireless User Equipment, UE, where conventional LI techniques are not applicable or operable when a user is activating and using a service application which content is distributed to a RAN 160 or the UE 170.

The main content functionality is implemented as a main content functionality means 132 in the first node. The distributed content functionality means is implemented as distributed content functionality means 162, 172 in the RAN or the UE.

Abstract: Network node and base station and methods therein for deriving a permanent identifier, such as an IMSI, for a UE in a cellular communication system of LTE type. The solution involves the use of a request for an inter-RAT handover, where the request comprises a temporary identifier of a process associated with the UE of which a permanent identifier is to be derived. The access to a permanent UE identifier is enabled in a radio access network where such an identifier is not readily available. The solution does not require any changes to procedures or nodes in the core network.
