摘要： The present invention relates to a method of registering a mobile station in a cellular mobile radio system in which areas, each including a plurality of cells, form registration areas. Each registration area (RA1, RA2, RA3, . . . ) has its own identity (X). According to the proposed method, individual location areas are defined whenever registering a given mobile station with the intention of avoiding an unnecessarily high number of registrations in border areas of the different registration areas. A location area may have the form of a list of registration areas (X1, X2, X3, . . . ), which is stored in a mobile station (MS), or may be stored in the system (HLR, MSC) and transmitted to the mobile station (MS) via a base station (BS) in a given registration area, in conjunction with registration of the mobile station in this area. A new registration is made only if the mobile station enters a service area that belongs to a registration area whose identity (X) is not found on the stored list of registration areas (X1, X2, X3, . . . ).
摘要翻译：本发明涉及在蜂窝移动无线电系统中注册移动台的方法，其中每个包括多个小区的区域形成登记区域。每个注册区域（RA1，RA2，RA3，...）都有自己的身份（X）。根据所提出的方法，每当注册给定的移动台时定义个别位置区域，目的是避免在不同注册区域的边界区域中不必要的高数量的注册。位置区域可以具有存储在移动站（MS）中的注册区域（X1，X2，X3等）的列表的形式，或者可以存储在系统（HLR，MSC）中并被发送结合移动台在该区域的注册，经由基站（BS）在给定的注册区域中向移动台（MS）发送。仅当移动台进入属于登记区域（X1，X2，X3，...）所存在的名单（X）的身份（X）的注册区域的服务区域时才进行新的注册。

摘要： A method for broadcasting information in a cellular communication system comprising at least one base station with an antenna array and a plurality of mobile stations is disclosed. The common information is preprocessed to create orthogonal signals. The orthogonal signals are then beam formed so that the orthogonal signals are delivered to the different elements in the array antenna. The orthogonal signals are transmitted and then received at at least one mobile station. The signals are then processed at the mobile station to decipher the common information from the orthogonal signals.

摘要： The present invention relates to the technique of handover in mobile telephony. A new Transcoder and Rate Adaptation Unit (100 FIG. 3) is introduced which provides two uplink (230, 250 respectively, FIG. 3) and two downlink (240, 260 respectively, FIG. 3) channels. The use of these two channels (230, 250 respectively, FIG. 3) on the uplink during handover provides for the use of distributed handover on the uplink. The result minimizes the audible interruption during handover by minimizing the loss of Traffic Channel frames to what is possible within the GSM standard. Additionally, interruption of the speech or background noise during these lost frames is masked by an error concealment algorithm, since the Transcoder and Rate Adaptation Unit (100 FIG. 3) still has information from the Base Transceiver Station responsible for transmission before the handover.
摘要翻译：本发明涉及移动电话中的切换技术。引入了新的代码转换器和速率适配单元（100图3），其提供两个上行链路（分别为230,250，图3）和两个下行链路（分别为240,260，图3）信道。在切换期间在上行链路上使用这两个信道（分别为230,250，图3）提供了在上行链路上使用分布式切换。该结果通过最小化在GSM标准中可能的业务信道帧的损失来最小化切换期间的可听到的中断。另外，在这些丢帧中的语音或背景噪声的中断被错误隐藏算法掩蔽，因为代码转换器和速率适配单元（100图3）仍然具有来自负责在切换之前发送的基站收发信机的信息。

摘要： In a cellular mobile telecommunication system, particularly a Global System for Mobile Communications (GSM) system, a method and apparatus determine the geographical position of a mobile station. The distance between the mobile station and a radio base station is estimated from the propagation delay. The propagation delay is determined according to the present method when the mobile station sends access bursts to the base station, which measures the access delay of the arrived bursts in the same way as an ordinary handover. However, no confirmation of received access bursts is sent from the base station to the mobile station and therefore the handover attempt is terminated. The connection between the mobile station and the previous base station is re-established. The measured access delay is proportional to the propagation delay and thereby also to the distance to the mobile station. The mobile position can be determined with good accuracy if values from at least three base stations are obtained, although with less accuracy if only two values are obtained. Also, an access delay measured by earlier known methods can be used together with measurements achieved with the present method to determine the mobile position.
摘要翻译：在蜂窝移动电信系统，特别是全球移动通信系统（GSM）系统中，方法和装置确定移动台的地理位置。从传播延迟估计移动台与无线基站之间的距离。当移动台向基站发送接入脉冲串时，根据本方法确定传播延迟，该基站以与普通切换相同的方式测量到达突发的接入延迟。然而，没有从基站向移动台发送接收到的接入突发的确认，因此终止切换尝试。移动台与先前的基站之间的连接被重新建立。测量的访问延迟与传播延迟成比例，从而与移动台的距离成比例。如果获得来自至少三个基站的值，则可以以高精度确定移动位置，尽管如果仅获得两个值，则精度较低。此外，通过早期已知方法测量的访问延迟可以与通过本方法实现的测量一起使用以确定移动位置。

摘要： A method and device avoid repeated registration attempts to register on PLMNs which do not allow registration for a mobile terminal while permitting attempts to register on PLMNs earlier inserted in a list of a number of identities of rejected PLMNs in a storage in the terminal but which may allow registration at a later time. At least a part of the list is erasable to be erased from time to time. Surplus identities of rejected PLMNs on a non-volatile part of the list are transferred to the erasable part of the list at overflow of the non-erasable list.

摘要： A method for establishing a new broadcast control channel carrier frequency within a cell without disturbing ongoing call traffic is disclosed. A cell having a base station transmitting broadcast control channel data over an existing BCCH carrier frequency establishes a second BCCH carrier frequency within the cell. During a first time period BCCH data is transmitted on the existing first BCCH carrier frequency. During a second time period, both the existing and new BCCH carrier frequencies carry BCCH data to enable surrounding mobile stations to detect and recognize both carriers. The transmission of the old BCCH carrier frequency is then discontinued during a third time period, such that the broadcast control channel data is only transmitted on the new BCCH carrier frequency.
