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.

A base station is controlled inactively provided that no radio signal is received from a mobile terminal in the radio range thereof while radio signals can still be receive from mobile terminals. An inactively controlled base station is once again controlled actively when a radio signal of at least one mobile terminal is received. The radio range, of the base station, is deactivated while radio signals can be received from the mobile terminal when the base station is controlled inactively. Thus, the number of actively controlled base station may be minimized and the environmental impact of radio signals caused by the base stations reduced.

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.

A method for operating a wireless telephone system to provide emergency service for a wireless telephone operating in the wireless telephone system. In the present invention, the wireless telephone system receives a request to connect the wireless phone to a predetermined telephone number from the wireless telephone. The telephone system then queries the wireless telephone for a unique identifying number identifying the wireless telephone. The unique identifying number enables the wireless telephone system to connect the wireless telephone to the wireless telephone system. The wireless telephone system maintains a set of direct inward dialing numbers (DIDs) that are used exclusively for emergency calls. Each of the DID allows a caller outside of the wireless telephone system to direct a call to a telephone within the wireless telephone system. The emergency call is assigned one of these DIDs and that DID is linked to the unique identifying number of the telephone placing the emergency call. The wireless telephone is then connected to an emergency operator and the emergency operator is given the assigned DID. The DID enables a call from the emergency operator to the wireless telephone through the wireless telephone system. In one embodiment of the present invention, the DID assigned to the wireless telephone also identifies the antenna closest to the wireless telephone. The assignment between the DID and the unique identifying number is terminated after a predetermined period of time which may be altered by the caller or those servicing the emergency call.
