The present disclosure relates to a method of controlling power supply units (-) of a base station (), and a device () performing the method. In an aspect, a method of a base station scheduling device () of controlling power supply units (-) of a base station () is provided. The method comprises acquiring (S-) information indicating a value of voltage input to at least one of the power supply units (-) of the base station (), determining (S) from said value if the voltage input to said at least one of the power supply units (-) is sufficient, and if not determining (S) power demand of the base station (), and deactivating (S) said at least one power supply unit, if remaining power supply units (-) is capable of supplying the demanded power.

Method for improving base station efficiency and power consumption

A method for managing allocation of network resources at a site in a communication network is disclosed. The method is performed by a resource manager and comprises receiving a notification of an event occurring at a network entity, the network entity being associated with the site and with a network operator. The event comprises at least one of a performance event, a fault event or an update event. The method further comprises determining an implication of the notified event for traffic flow in the network and determining, on the basis of the implication of the notified event for traffic flow in the network, an operational requirement to compensate for the event. The method further comprises obtaining configuration information for fulfilment of the operational requirement and instructing an infrastructure manager for the site to allocate network resources in accordance with the obtained configuration information in order to satisfy the operational requirement.

Method and apparatus for network resource allocation

Mechanisms for migration of a stateless computation service in a mobile communication network. A method, performed by a control node comprises obtaining, from a core network node in the mobile communication network, information indicative of a need to migrate the stateless computation service from a source compute node in the mobile communication network. The need results from resource utilization at the source compute node is too high, and/or a demand from user equipment for the stateless computation service elsewhere in the mobile communication network. The method comprises initiating migration of the stateless computation service from the source compute node to a target compute node in the mobile communication network for hosting of the stateless computation service at the target compute node.

Migration of computational service

A server (), a client device () and methods therein, for handling cached content resources. When the client device () sends a download request () in a downloading session, the server () identifies () at least one content resource deemed to be potentially needed later in the downloading session. The server () then sends a cache map to the client device () in a response to the download request. The cache map comprises a pre-fetch indication indicating that the identified at least one content resource should be pre-fetched by the client device () from a cache () containing the identified at least one content resource. Thereby, the client device is able to pre-fetch () the content resources before the performance of communication may become reduced so that communication with the cache () is difficult or even impossible, e.g. due to deteriorated radio conditions or congestion in the communication network.

Server, client device and methods therein for handling

A server (), a client device () and methods therein, for handling cached content resources. When receiving () a request from the client device () in a downloading session, the server () identifies () a set of caches () that can be accessed by the client device (). The server () then sends () a cache map to the client device () indicating that a first content resource is stored in a first cache () of the identified set of caches and a second content resource is stored in a second cache () of the identified set of caches. Thereby, the server () is able to adapt the cache map depending on which caches can be accessed by the client device (), to ensure that the client device () can retrieve the content resources in an efficient manner.

An Application Scope Platform and a method for enabling communication between a Web Application, which is adapted to run on a first Processor of a User Device, and which is being accessible via a Web Client of the User Device, and an Application Scope, which is executable on the Application Scope Platform. The Application Scope Platform comprises a Process Manager, adapted to create and manage an event triggered Application Scope, a Web Server and a Communication Interface adapted to enable the Web Application to communicate with the Application Scope Platform via said Web Client. The Application Scope Platform being adapted to run on a second Processor, and to communicate with the Web Application, which is an Application Scope enabled Web Application, irrespective of the state of the Processor, the Web Client and/or said Web Application.

Method and arrangements for application scope management

A method and apparatus for determining a location address for shared packet switched data. The data is to be accessible by a user of a first device and a user of a second device. A symmetric function is applied to a known identifier associated with the first device and a known identifier associated with the second device. The result of the function can then be used as an address for data to be accessible by users of both the first device and the second device, the data being stored on a remote server at a location defined by the address. The method ensures that the same address is calculated regardless of which identifier is used first, and that both devices can calculate the address without requiring any further signalling or capability/discovery mechanism.
