A method for encoding a connection between a base () and a mobile part (), and a computer program product is povided. The method comprises generating a key agreed to by the base () and the mobile part () during a first connection, wherein the key comprises an index assigned by the base during the first connection, and b) using the generated key for a second connection between the base () and the mobile part (), wherein the data to be transferred between the base () and the mobile part () are identified and encoded using the index assigned to the key. The security of wireless data transfer is thus increased in a simple and low-cost manner.

Encoding a connection between a base and a mobile part

In order to be able to control the creation of a user channel connection in a communication system using wireless communication between at least one mobile part and one wired part in such a way that a user channel connection is established more quickly upon a connection request indicated by the mobile part or the wired part for the purpose of transmitting user data and, at the same time, due to market requirements, no synchronization pulses are sent by the wired part in the idle state, an initiating device of the communication system (for example, for an incoming call: base station; for an outgoing call: mobile part) sends, from an asynchronous idle state, synchronization pulses (SB) to all available physical resources. Due to the plurality of the sent, available synchronization pulses (SB), rapid synchronization is ensured because the probability is sufficiently increased thereby that a pulse will fall in the search window of a receiver.

The invention relates to a method for operating at least one mobile radio transmission/radio receiving device (Intern) operating according to a wireless telecommunications standard on a stationary radio transmission/radio receiving device (Basis) operating according to the wireless telecommunications standard, and a stationary radio transmission/radio receiving device (Basis) and a mobile radio transmission/radio receiving device (Intern) for carrying out the method. The invention relates to a method for operating at least one mobile radio transmission/radio receiving device (Intern) operating according to a wireless telecommunications standard, particularly a DECT derivative, on a stationary radio transmission/radio receiving device (Basis) operating according to a wireless telecommunications standard, which stationary radio transmission/radio receiving device store at least one list, wherein at least one protocol notification relating to the list is generated by the mobile radio transmission/radio receiving device (Intern) and is transmitted (S, S, S) to the stationary radio transmission/radio receiving device (Basis) such that the mobile radio transmission/radio receiving device (Intern) manipulates at least parts of the accesses relating to the list by means of the stationary radio transmission/radio receiving device (Basis). The invention further relates to a stationary (Basis) and mobile (Intern) radio transmission/radio receiving device having means for carrying out the method.

In order to prevent in a communication system covering at least one cell for wireless communication, the system having a line-limited or across-line wireless direct communication possibility between mobile phones that is synchronized with a base station, that mobile parts attempt to synchronize in the communication system with a continuous broadcast downlink service provided by a hybrid mobile part, it is proposed to mark the continuous broadcast downlink service of the hybrid mobile part, which assumes the role of a radio fixed part, so that mobile parts, which want to synchronize with a true radio fixed part, can detect that the service provided by the hybrid mobile part is not permanently available, or even incomplete.

During the transmission of subscriber-specific data, particularly via a transfer medium and according to a transmission principle based on time slot transmission with time slot separation, the transfer medium used by several subscribers can also be efficiently used when the data rates of the data transmitted in the transmission direction (SRI) and the reception direction (ERI) for at least one subscriber using the transmission are differently, i.e. asymmetrically distributed. To this end, the data to be transmitted for each subscriber are transmitted, as in the case of a symmetric data distribution, in at least two time slots (ZS) per a periodically returning time frame (ZR, ZRZR) and corresponding to the asymmetrical distribution of the ratio of a number of transmission data packets (SDP) to reception data packets (EDP) in a plurality n half time frame of the time frame (ZR, ZRZR) with n being greater or equal to 2 or &#x3b5; N.
