A method for managing a virtual radio access network which serves a radio cell is provided. The method includes selecting, based on a radio access technology of the radio cell, a construction scheme for the virtual radio access network in a repository. Further, the method includes querying, from the repository, at least one software component associated to the construction scheme. The software component represents a virtualized network function of the virtual radio access network. The method additionally includes setting up, using the software component, the virtualized network function on a runtime platform according to the construction scheme.

In order to allow for performing baseband processing tasks by multiple cooperating baseband processing devices () such that the real time constraints are met, it is proposed that the method () comprise determining () a delay metric (RTT_BBU) that depends on a network delay between the network element () and at least one baseband processing device () of the plurality of baseband processing devices (), wherein the delay metric (RTT_BBU) is determined before an event (e) occurs that triggers allocation or reallocation of processing resources of the at least one baseband processing device (), and selecting () the at least one baseband processing device of the plurality of baseband processing devices for remote processing depending on the delay metric (RTT_BBU).

Method for operating a network element of a wireless communication network and network element

Embodiments relate to a baseband signal processing cluster of a wireless communication network, the baseband signal processing cluster comprising baseband signal processing units, wherein at least one of the baseband signal processing units is coupled to at least one remote radio head of the wireless communication network and comprises a unit-specific processing resource management entity operable to manage a processing resource allocation within its associated baseband signal processing unit, an intra-cluster processing resource management entity coupled to at least one of the unit-specific processing resource management entities and operable to manage a processing resource allocation among the baseband signal processing units, and an inter-cluster processing resource management entity coupled to the intra-cluster processing resource management entity and operable to exchange information with at least one remote inter-cluster processing resource management entity of a remote baseband signal processing cluster of the wireless communication network to effect a remote processing resource allocation.

Baseband signal processing cluster

The present invention provides a method and an apparatus for controlling a communications system that includes a mobile wireless device, a first and a second base station and a radio network controller. The communications system may allocate frequency bands to users on a multiplicity of channels associated with a multi-layer access network across at least two cells communicatively coupled to a first and a second base station, respectively. The method comprises monitoring a radio emission parameter associated with the first and second base stations that communicate with the mobile wireless device. A radio emission parameter associated with the first and second base stations, such as signal strength or quality, is monitored, to select a target cell among a set of candidate cells for the mobile wireless device and to transfer the mobile wireless device from a first frequency band to a second frequency band. For example, radio resource management algorithms may cause emission-controlled cell selection and inter-frequency handover from a first frequency band to a second frequency band with a transmit power level lower than that of the first frequency band. In accordance with one aspect of the instant application, electromagnetic exposure to a user of the mobile wireless device is substantially decreased, resulting in lower energy costs and reduced environmental impacts.
