The present disclosure relates to a computer-implemented method for optimizing signal reception in a cellular communications network with a plurality of antennas for communicating with terminals. The method comprising: specifying a set S of candidate sites s and a set D of candidate antenna configurations, CAC, for placement of one or more antennas at the candidate sites s; specifying a set P of pixels p, each pixel p corresponding to a geographic location within a service area for which signal reception should be optimized; selecting a set Bp of candidate best servers, CBS, for each pixel p based on an expected radio signal strength for a terminal at the geographic location corresponding to the respective pixel p, each set Bp comprising zero or more candidate servers corresponding to one of the candidate sites s and one of the CAC; and determining a set of proposed servers. The determination is based at least on: an optimized aggregated signal-to-noise ratio, SNR, computed for all pixels p in case all of the proposed servers of the set which are built at the corresponding candidate sites s with the corresponding CAC, and a first restriction requiring that, from each set Bp of CBS, at most a single CBS is included in the set of proposed servers. The present disclosure further relates to a quantum concept processor and a computer program.

The invention pertains to a computer-implemented method for optimizing an assignment of frequencies (f) to cells (C) of a mobile communications network (1). The cells (C) are distributed for communication within the mobile communications network (1). A set of unplanned cells (2) in the mobile communications network (1) is specified. For each unplanned cell (2) a set of frequencies (f) to be potentially assigned to this unplanned cell (2) is specified. Frequency interference probabilities (p) of selected cell pairs are calculated, wherein each cell pair defines a relation of an unplanned cell (2) to another cell (c) within the mobile communications network (1). Then, terms of a stress function are formulated, each term connecting a calculated frequency interference probability (p) of a respective cell pair with a frequency relation between the cells (2, c) of the respective cell pair. An optimized assignment of frequencies (f) is determined by using a quantum concept processor (7), thereby selecting for each unplanned cell (2) a sub-set of frequencies (f) from the respective set of frequencies, such that the stress function is minimized.

The invention relates to a method for an improved authentication, authorization and accounting functionality within an access network of a telecommunications network and/or an improved access network architecture, wherein the telecommunications network comprises an authentication server entity providing an authentication, authorization and accounting functionality, AAA, as well as a policy server functionality, wherein the telecommunications network furthermore comprises a plurality of service edge entities, each service edge entity providing a service enabling functionality to subscriber devices connected to the telecommunications network, wherein - in order to enable or to provide communication services to the subscriber devices requesting such communication services - AAA-related messages are sent and received by both the authentication server entity and the service edge entity via an access orchestrator entity as part of the access network, the AAA-related messages conforming to or using an access protocol used between the authentication server entity and the service edge entity, wherein, in order for an improved authentication, authorization and accounting functionality and/or access network architecture to be realized, the method comprises the following steps: -- in a first step, a first AAA-related message, is sent by the authentication server entity, and received by the access orchestrator entity, the first AAA-related message comprising, besides at least one standardized message attribute according to the used access protocol, also at least one vendor-specific message attribute, -- in a second step, subsequent to the first step, the access orchestrator entity sends a second AAA-related message to the service edge entity, the second AAA-related message solely comprising the at least one standardized message attribute according to the used access protocol, -- in a third step, subsequent to the first step and prior, during or after the second step, the access orchestrator entity sends at least one third AAA-related message to the service edge entity, the at least one third AAA-related message corresponding to a message according to an application programming interface, API, or to a further access protocol.
