Abstract: In a packet transmission system, especially wireless transmission system, where data is transmitted in packets at different error protection levels and where the error protection level of one packet (= the succeeding packet) may differ from the error protection level of a preceding packet without providing code termination between the said preceding and the said succeeding packet the performance may degrade in case a different error protection level is used by the preceding packet and the succeeding packet. The invention proposes in these cases to insert a supplementary packet between the preceding and the succeeding packet whereby the error protection level of the supplementary packet is higher than the lowest error protection level that is used either by the preceding or the succeeding packet.

Abstract: The invention relates to a method, a communication system and a switching apparatus which perform a switching of calls to another channel (CC2) when two or more calls simultaneously attempt to use a channel (CC1). According to the invention, each channel is first set (S3, S4, S5, S8) to a first call state when first attempting to use a channel. In the first call state, first predetermined transmission conditions must be satisfied (55) in order that the call proceeds to a second call state (S9, S10, S11, S14) in which second predetermined transmission conditions (S11) must be satisfied. Due to this progression of the call through a first, second and possibly higher order call states, it can be ensured that always a new call will always accomplish a hand-over to a new channel (CC2). The invention finds particular application when a channel may be used several times by several calls in a communication network of a channel re-use type and a substantial interferenceof the at least two calls occur when they use the same channel inclose proximity, e.g. when handing over a mobile telephone of a GSM system to a GSM-based cordless telephone system.

Abstract translation: 本发明涉及当两个或多个呼叫同时尝试使用信道（CC1）时执行对另一信道（CC2）的呼叫切换的方法，通信系统和交换装置。 根据本发明，当首次尝试使用信道时，首先将每个信道（S3，S4，S5，S8）设置为第一呼叫状态。 在第一呼叫状态下，必须满足第一预定发送条件（55），以便呼叫进行到必须满足第二预定发送条件（S11）的第二呼叫状态（S9，S10，S11，S14）。 由于通过第一，第二和可能更高阶的呼叫状态的呼叫的这种进展，可以确保总是新的呼叫将总是完成对新信道（CC2）的切换。 当在通道重用类型的通信网络中通过多个呼叫可以使用多个信道时，本发明发现具体应用，并且当它们使用相同信道时，发生至少两个呼叫的实质性干扰，例如， 当将GSM系统的移动电话交给基于GSM的无绳电话系统时。

Abstract: The invention discloses a method for use in a wireless communications system with a plurality of broadcasting nodes, comprising the step of enabling one node in the system to function as a central node in said system and letting said node enable measurements on at least one frequency in a frequency band used by the system. Said measurements are carried out to detect if said at least one frequency is being utilized by a transmitter foreign to the system. Preferably, the measurement is enabled by means of the node transmitting a message to other nodes in the system, said message being a message pre-defined within the system as a message prohibiting all nodes from transmitting during a certain interval, said message being transmitted after the system has been detected by the node to be silent during a predefined interval between frame transmissions from the nodes in the system.

Abstract: Interference Measurements in a Wireless Communications SystemA method and a transmitting unit for performing an interference measurement in a multiple access wireless communications system utilizing a carrier sensing technique is described. In accordance with the carrier sensing technique, it is monitored during a sensing period (T min ) if a carrier is idle. A continuous or quasi-continuous interference measurement is performed on the carrier during a measurement period (T M ) which is typically longer than the sensing period (T min ). While performing the interference measurement, pulses are transmitted on the carrier such that an interval between the end of a pulse and the beginning of the next pulse is typically shorter than the sensing period (T min ). The interference measurements preferably relate to detection of interference from radar signals or radar like signals.

Abstract: In a packet transmission system, especially wireless transmission system, where data is transmitted in packets at different error protection levels and where the error protection level of one packet (= the succeeding packet) may differ from the error protection level of a preceding packet without providing code termination between the said preceding and the said succeeding packet the performance may degrade in case a different error protection level is used by the preceding packet and the succeeding packet. The invention proposes in these cases to insert a supplementary packet between the preceding and the succeeding packet whereby the error protection level of the supplementary packet is higher than the lowest error protection level that is used either by the preceding or the succeeding packet.

Abstract: In two superimposing cellular communication systems using the same frequencies, whereby the additional cellular communication system was not considered in the frequency planning of one of the cellular communication systems, frequencies are to be allocated to the additional cellular communication system in a way that they do not interfere with the system and only cause small disturbances. For determining and selecting frequencies a method and a device are provided whereby by means of determining a medium field strength f1'( tau ), f2'( tau ),...,fi'( tau ) of each possible frequency (i = 1,2,...,n), by means of selecting a number (N) of suitable frequencies and the medium value of which, a degree of quality is calculated. In dependence on the quality a new determination of the medium field strengths of each frequency is postponed in terms of time, for being able to react on changes faster or slower. By selecting the values for good quality, interferences with the superimposed system are obtained. A device and a method are provided, which are flexible, involve only low interferences and disturbances and which are easy to implement.
