    • A method and system for configuring a radio interface between a mobile station and a base station in a time-division multiplex mobile radio system for packet data transmission, wherein time slots for signalling in the uplink direction are allocated by a base station to the mobile stations in accordance with a sequence which can be predetermined independently of packet data transmission. The fixed allocation of a time slot for signalling, in addition to mobile stations to which no physical channel is currently allocated, allows the base station to carry out continuous measurement relating to the radio interface. Thus, when packet data transmission resumes, immediately valid measurements are available for configuration of the radio interface.
    • 一种用于在用于分组数据传输的时分复用移动无线电系统中配置移动台和基站之间的无线接口的方法和系统,其中在上行链路方向的用于信令的时隙由基站分配给移动台 根据可以独立于分组数据传输来预定的序列。 除了当前没有分配物理信道的移动台之外,用于信令的时隙的固定分配允许基站执行与无线电接口相关的连续测量。 因此,当分组数据传输恢复时,立即有效的测量可用于无线电接口的配置。

    • In a communications network, a first address information is transmitted from a first communication terminal equipment to a first switching node for setting up a communication connection, whereby first identification features are contained in the first address information. The first switching node interprets the first address information with the first identification features and derives a second address information for addressing a first address converter therefrom. At least parts of the first identification features are communicated to the first address converter. Second identification features are generated from the first identification features, said second identification features serving the purpose of addressing a second switching node. The communication connection between the first and second switching node is set up with the second identification features.

    • In methods for signal transmission, a first radio burst is inventively transmitted in a time slot of the radio interface, in which a transmission-side synchronization of the transmission of the first radio burst occurs, so that the first radio burst arrives at the receiving radio station at a predetermined point in time within the time slot. At least one second radio burst that can be interpreted separately from the first radio burst is transmitted in the same time slot. The invention can be utilized for designing the access method (random access) in packet data services (GPRS) of the GSM mobile radio telephone system or in a TDD transmission mode of the third mobile radio telephone generation. This method may also be used to transmit many very short messages.

    • A method establishes a connection between a source network with a source network resource manager and a target network with a target network resource manager. According to the method, a connection control unit of the source network transmits a connection establishment signal to a connection control unit of the target network and—parallel to this—a reservation request to the target network resource manager. The target network resource reserves the requested resources and forwards the reservation request towards the target network resource manager, which also reserves the requested resources and transmits reservation information regarding the success of the resource reservations to the connection control unit of the target network.

    • The subject matter of the invention proceeds from an encryption of the information for the radio transmission in an access network (ACN) as well as an authentication in at least one core network (CON1, CON2). Inventively, public keys (PUK1-MT, PUK-BS) are mutually transmitted between a mobile station (MT) and the base station (BS) via the radio interface (AI), and the public key (PUK1-MT or PUK-BS) received by the base station (BS) or mobile station (MT) is employed for the encryption of the information to be subsequently sent via the radio interface. On the basis of a private key (PRK1-MT, PRK1-BS) that is allocated to the transmitted, public key (PUK1-MT, PUK-BS) in the mobile station (MT) or in the base station (BS), the encrypted information received by the mobile station or base station can be deciphered. Following the encryption procedure, a subscriber identity mobile card (SIM) of the mobile station implements the authentication of the respective core network (CON1, CON2), and authentication equipment (AC, AC′) of the core network implements the authentication of the subscriber on the basis of the mutually transmitted, encrypted information.
    • 本发明的主题从对接入网络(ACN)中的无线电传输的信息的加密以及至少一个核心网络(CON 1,CON 2)中的认证进行。 本发明的公钥(PUK 1 -MT,PUK-BS)经由无线接口(AI)与移动台(MT)和基站(BS)之间相互发送,而公钥(PUK 1 -MT或PUK -BS)由基站(BS)或移动台(MT)接收的信息用于通过无线电接口随后发送的信息的加密。 基于分配给移动站(MT)或基站(MTK)中的所发送的公开密钥(PUK 1 -MT,PUK-BS)的私钥(PRK 1 -MT,PRK 1 -BS) BS),可以解密由移动台或基站接收到的加密信息。 在加密过程之后,移动台的用户身份移动卡(SIM)实现各自的核心网(CON1,CON2)的认证,核心网的认证设备(AC,AC')实现认证 基于相互发送的加密信息的用户。
