摘要： The invention relates to a method for mutual synchronization of the transmitter's speech encoder and the receiver's speech decoder in a communication system utilizing discontinuous transmitter between the transmitter and the receiver. The discontinuous transmission comprises temporally sequential frame periods of which some periods will contain transmitted frames and some periods contain no transmission; whereby the method contains steps to generate information transmission periods (200) comprising at least one frame and containing information given by a user to said transmitter device, and silence periods (208, 209) having a length of at least one frame period and containing other information than that given by the user. The discontinuous transmission further comprises an irregularly occurring period (T) comprising at least one frame between the information transmission period (200) and the next silence period (208, 209), the irregular period forming a hangover period to determine the information relating to the silence period. In the method according to the invention the number of frame periods is counted in the receiver until a certain moment; the beginning of said silence period (208, 209) is detected; and based on said counted number of frame periods and the beginning of the silence period (208, 209) it is decided whether or not there is a hangover period (T) of said type between said information transmission period (200) and the silence period (208) following the information transmission period.

摘要： The destination zone of a call is defined (2) according to the prior art in a wireless pay phone, for example, by analyzing a selected phone number, and the present invention is characterized in that, additionally, the location of the pay phone is defined (3) and the originating zone of the call is defined based on the location, and the charge rate is set based on at least the originating zone and destination zone of the call. The charge rate is advantageously set by means of a tariffing algorithm realized in the pay phone, which algorithm specifies several charge rate classes and corresponding parameter values, which set (7) a charge rate corresponding to a charge rate class. To set a charge rate class, first a distance class may be set (5) based on the originating zone and destination zone, and then a charge rate class may be set (6) based on the distance class and possibly other factors. The present invention makes it possible to realize a tariffing within a wireless pay phone itself, which functions sufficiently well and fairly even through the pay phone roams extensively, for example, in different countries.

摘要： The method according to the invention relates in general to transmission in cellular telecommunication systems and in particular to optimization of the data transfer mode. In the method according to the invention the data transfer mode is controlled using the downlink quality measured by the mobile station (MS) and the uplink quality measured by the base station (BTS). For transparent connections it can be determined a desired maximum threshold for the RXQUAL value, and when the uplink or downlink RXQUAL exceeds that maximum threshold (i.e. the bit error rate BER exceeds the maximum value), a more error-tolerant channel coding of a lower transmission speed is taken into use and the channel resources available are increased, e.g. by growing the number of time slots to keep the user data transmission rate constant.

摘要： The invention relates to a method for transmitting speech and data simultaneously on a circuit switched two-way connection of a mobile communications system, which transfers speech and other data by use of discontinuous transmission, DTX, in which the sending is discontinued when it is indicated that there is no information to be sent, and continued when it is indicated that there is information to be sent. In accordance with the method of the invention, the data to be sent are stored in buffer means and wait to be sent. When it is indicated that there is no more information to be sent, the data stored in buffer means are sent until there is no more data to be sent or until it is indicated that there is information, speech or other data to be sent, in which case the sending of data is discontinued and the sending of speech or other data is re-started. So the transfer of data takes place as a background process during transfer of speech or other data. The data are arranged into frame structures while being stored in the buffer. The data are separated, for example, by identifiers placed at the beginning of the frame structures. The same traffic channel can be used for transferring both data and speech or other data. An alternative is to transfer the data on a fast associated control channel that belongs to the same circuit switched connection as the traffic channel.
摘要翻译：本发明涉及一种用于在移动通信系统的电路交换双向连接上同时发送语音和数据的方法，移动通信系统通过使用不连续传输DTX传送语音和其他数据，其中发送在指示时停止发送没有信息被发送，并且当指示存在要发送的信息时继续。根据本发明的方法，要发送的数据被存储在缓冲装置中并等待发送。当指示不再有要发送的信息时，发送存储在缓冲装置中的数据，直到没有更多的数据被发送，或者直到它被指示存在要发送的信息，语音或其他数据为止哪种情况下中断数据的发送，并重新开始语音或其他数据的发送。因此，在传输语音或其他数据期间，数据传输是作为后台进程发生的。数据被布置成帧结构，同时被存储在缓冲器中。数据被分离，例如，被放置在帧结构开始处的标识符。相同的业务信道可用于传输数据和语音或其他数据。另一种方法是将数据传输到属于与业务信道相同的电路交换连接的快速关联控制信道上。
