摘要： A method in a cellular communication system provides selection of a channel for use in a pending communications operation, the selection reducing the likelihood of co-channel interference. In each co-channel cell, frequencies from the cell's frequency group are ordered in a sequence. A different frequency in each cell is designated as having a highest priority. Successively lower priorities are then assigned, in each cell, to remaining frequencies in sequence. Then, in each cell, selection is made by identifying the available frequency having the highest priority. The method may be modified to provide for even distribution of hardware use by changing the priorities in each cell periodically. The method may also be modified for use in a fully synchronized time division multiple access (TDMA) system by performing the above steps with respect to channels instead of frequencies. The method may further be modified for use in a pseudo-synchronized TDMA system (i.e., one in which the TDMA time slots of one cell are slowly shifting with respect to the time slots of another cell) by selecting, instead of the highest priority channel, one having a lower priority based on a time difference between corresponding time slots in two co-channel cells.
摘要翻译：蜂窝通信系统中的一种方法提供了在未决通信操作中使用的信道的选择，该选择降低了同信道干扰的可能性。在每个共通道单元中，来自单元的频率组的频率按顺序排列。每个单元中的不同频率被指定为具有最高优先级。然后在每个单元格中依次将顺序降低的优先顺序分配给剩余的频率。然后，在每个单元中，通过识别具有最高优先级的可用频率进行选择。可以修改该方法以通过周期性地改变每个小区中的优先级来提供硬件使用的均匀分布。该方法还可以通过相对于信道而不是频率执行上述步骤而被修改用于完全同步的时分多址（TDMA）系统。该方法还可以被修改用于伪同步TDMA系统（即，一个小区的TDMA时隙相对于另一个小区的时隙缓慢移位的方式），而不是选择最高优先级信道基于两个同信道小区中对应的时隙之间的时间差，具有较低优先权的一个。

摘要： A multi-level layered cellular radio architecture serves mobile subscriber stations (21) moving within the system. Best server selection is performed for the mobile stations (21) by assigning within each cell (C1-C10) a preference value to each other one of the cells (C1-C10) with which is associated by proximity of service area. The strength of the radio signal received by the mobile station (21) from the serving cell (C1-C10) as well as the radio channels of associated cells (C1-C10) is measured. A decision as to the best serving cell (C1-C10) for the mobile station (21) is made based upon both the preference value of the associated cells (C1-C10) and the signal strength of their respective radio channels.

摘要： A method of avoiding undesirable interferences between services in a telecommunications system that includes basic software (51) for a basic service and supplemental software for services supplemental to the basic service. The supplemental software is divided into action software (52) which acts solely on the basic service, and supplemental software (59) which acts on the remaining supplemental software. According to the invention, a supplemental service is represented by action elements. Combinations of action elements form nodes in a mathematical binomial tree. Only those combinations which correspond to interference, i.e. an undesirable behaviour, between supplemental services will form a number of structures, called interference event trees (55). Before a supplemental service can be executed, its action elements are compared with nodes in the interference event trees (55), with the intention of ascertaining whether or not the former coincide with action elements belonging to the nodes in the latter. Only those interference event nodes whose sets of action elements are equivalent with the set of action elements of the supplemental service or a set thereof are selected. An interference event node whose set of action elements is a subset of the action elements of a node that has already been chosen cannot be selected. Interaction software (58) belonging to selected nodes in the interference event trees is added to the basic software (51).
摘要翻译：一种避免电信系统中的服务之间不期望的干扰的方法，其包括用于基本服务的基本软件（51）和用于补充基本服务的服务的补充软件。补充软件分为仅作用于基本服务的动作软件（52）和作用于剩余补充软件的补充软件（59）。根据本发明，补充服务由动作元件表示。动作元素的组合在数学二项式树中形成节点。只有对应于补充服务之间的干扰（即不期望的行为）的那些组合将形成被称为干扰事件树的多个结构（55）。在可以执行补充服务之前，将其动作元素与干扰事件树（55）中的节点进行比较，其目的是确定前者是否与属于后者中的节点的动作元素一致。仅选择其动作元素组与补充服务的一组动作元素或其一组相当的那些干扰事件节点。不能选择其动作元素集合是已经被选择的节点的动作元素的子集的干扰事件节点。属于干扰事件树中的选定节点的交互软件（58）被添加到基本软件（51）。

摘要： A receiver in a frame based radio communication system includes a speech decoder of the source-filter type which is controlled by means (20, 22, 24) including internal state variables updated on a frame by frame basis for modifying received filter parameters representing background sounds transmitted over a communication channel. The receiver includes means (12, 13, 14) for detecting frames containing transmission errors, means (16) for deciding whether a frame in which transmission errors have been detected is acceptable, and means (18) for concealing the detected transmission errors by restricting updating of at least one of the internal state variables if the detected frame is declared non-acceptable by the deciding means.

摘要： The invention relates to a method for handling calls to a terminal (MS) in a mobile telephone system of the kind in which the call is handled by an ISUP/IAM message which has a static relationship between the address (PRN) of the visitor location register (GLR-2) in the network in which the terminal roams, and the unique terminal identity (IMSI). If the visitor location register (GLR-2) has no data record relating to the unique identity (IMSI), an attempt is made to collect from the home location register (HLR-1) of the called subscriber the data that is required to complete the connection, this data being stored in the visitor location register (GLR-2). If the attempt is successful and the called subscriber is active, the connection is set up in a known manner with the aid of this data.

摘要： A discriminator (24) discriminates between stationary and non-stationary signals. The energy E(Ti) of the input signal is calculated in a number of windows Ti. These energy values are stored in a buffer (52), and from these stored values a test variable VT is calculated (54). This test variable comprises the ratio between the maximum energy value and the minimum energy value in the buffer. Finally, the test variable is tested against a stationarity limit gamma . If the test variable exceeds this limit the input signal is considered non-stationary. This discrimination is especially useful for discriminating between stationary and non-stationary background sounds in a mobile radio communication system.
