A method for controlling an energy storage system. The same battery system shall support multiple services at the same time. During a planning phase, the multiple services to be provided are determined, based on the market situation and the capabilities of the energy storage system, and prioritized according to predefined criteria. During an operation phase, the power and energy status of the energy storage system is periodically monitored, and compared against the power and energy demands of the multiple services, in order to determine whether at each time instance, the multiple services can indeed be supported at the same time. In case power and/or energy limits are exceeded by the multiple services, at least one service is interrupted to allow the operation of the energy storage system to be within power/energy limits again. The interrupted service(s) is resumed when the power/energy limits are met.

Method for controlling an energy storage system

The present invention relates to a method and to devices for transmitting and receiving data in a code division multiple access telecommunication system. A random access time window () is provided, which comprises a plurality of random access slots for transmitting random access data, for example from a mobile station () to a base station (). The plurality of random access slots in the random access time window () is divided into at least two groups, whereby the groups are allocated to respective priority classes, whereby the priority classes represent the transmission priorities of the random access data to be transmitted in the random access slots. The present invention allows a reduction in congestion on the random access slots for certain access types at the expense of other access types and a more efficient use of the random access time window.

Random access channel prioritization scheme

The present invention proposes communication devices () and a method for transmitting and receiving random access bursts in a random access channel of a digital telecommunication system. Thereby, a random access burst comprising a preamble part for acquiring a part of said random access channel and at least one message part for transmitting data in said acquired part of the random access channel is generated, whereby the number of message parts depends on an amount of data to be transmitted in the message parts. In case that two or more message parts are generated, each preceding message part comprises a continuation indicator indicating a succeeding message part. After transmission of such a random access burst, the continuation indicator is detected and a further part of the random access channel is reserved for the succeeding message part. Advantageously, the random access channel comprises a number of random access slots being divided into a first section containing contention based random access slots and a second section containing reservation based random access slots, whereby the preamble part of a random access burst comprising two or more message parts is transmitted in said second section. The present invention has the advantage that a higher amount of random access data can be transmitted within one random access burst in a simple way without enhancing the contention-based access to the random access channel.

Transmission of random access bursts with at least one message part

Random access channel priorization scheme

The present invention relates to a method and to devices ( ) for transmitting and receiving data in a code division multiple access telecommunication system. A random access time window ( ) is provided, which comprises a plurality of random access slots for transmitting random access data from at least one first communication device ( ) to a second communication device ( ). A partition point is determined, which defines a number of contention based random access slots and a number of reservation based random access slots in the random access time window on the basis of statistical information generated in at least one first communication device ( ). The random access time window ( ) is partitioned in a first and a second section on the basis of said partition point, whereby the first section contains contention based random access slots and the second section contains reservation based random access slots. The present invention thereby allows to dynamically adapt the random access time window resources to changing requirements and an optimal utilization of the resources.
