    摘要： The invention is a method and apparatus for providing an Alert With Information Message signal between a mobile switching center and a base station in a cellular communication system. The invention recognizes that current provisions of the IS-634 standard lack support for certain required functionality on the interface between a mobile switching center and a base station, or the A-Interface. An Alert With Information Message signal is introduced on the A-Interface to support the required functionality. Introduction of the Alert With Information Message provides support for reliable call processing on the A-Interface for the call waiting procedure, the hard handoff procedure, and the resolution of a glare condition.

    摘要： A system and method for providing mobile switching center (MSC) initiated service negotiation in a wireless communication system. If a new call arrives for a subscriber unit while the subscriber unit is already on the traffic channel, a change in the service configuration may allow the subscriber unit to receive the new call while preserving the old call. MSC initiated service negotiation may be used to establish the change in service configuration. The MSC transmits a Change Service Command message to the base station in whose coverage area the subscriber unit is located. The Change Service Command proposes a new service configuration to accommodate both the old and the new call. The base station, subscriber unit, and MSC may interchange further messages to modify the proposed service configuration if necessary. Messages are exchanged until the base station, subscriber unit, and MSC reach an agreement regarding the new service configuration. The present invention also provides support for soft handoff. The new service configuration is presented to all target base stations involved in the soft handoff, so that the subscriber unit may make use of the new service configuration while in soft handoff.

    摘要： An RF circuit switch system having particular use in an antenna diversity scheme for a CDPD system relies upon a comparison between current signal values on a selected antenna and a predetermined value based upon previous signal values measured on the same antenna. This comparison determines whether switching will occur from one antenna to another. Normally, the predetermined value will be adjusted based upon present signal strength on the selected antenna. Switching is normally attempted when there is a drop of approximately 10 dB in the signal strength of the selected antenna. If the signal strength in the other antenna is found to be less than that of the original antenna upon switching, an automatic switch back is carried out.

    摘要翻译： 在用于CDPD系统的天线分集方案中特别有用的RF电路开关系统依赖于基于在同一天线上测量的先前信号值在选定天线上的电流信号值与预定值之间的比较。 该比较确定是否从一个天线到另一个天线发生切换。 通常，将基于所选天线上的当前信号强度来调整预定值。 当所选天线的信号强度下降约10dB时，通常会尝试切换。 如果在切换时发现另一天线的信号强度小于原始天线的信号强度，则执行自动切换。

    摘要： A method of electronically moving portions of several different images on a CRT screen includes the steps of: storing a first image in one section of an image memory, and storing a second image in a different section of the image memory; storing control bits in a control memory which define high and low priority viewports on the screen and correlate portions of the first and second images to the high and low priority viewports respectively; displaying, in response to the stored control bits, the entire portion of the image in the high priority viewport and only the non-overlapping portion of the image in the low priority viewport by transferring the image portions from the image memory to the screen with no frame buffer therebetween; modifying at least some of the stored control bits to change the priorities of the high and low priority viewports to low and high respectively; and repeating the displaying step, in response to the modified control bits, to display the entire portion of the image in the new high priority viewport and only the non-overlapping portion of the image in the new low priority viewport.

    摘要： Methods and apparatus are presented for providing local authentication of subscribers travelling outside their home systems. A subscriber identification token 230 provides authentication support by generating a signature 370 based upon a key that is held secret from a mobile unit 220. A mobile unit 220 that is programmed to wrongfully retain keys from a subscriber identification token 230 after a subscriber has removed his or her token is prevented from subsequently accessing the subscriber's account.

    摘要： A system for electronically displaying portions of several different images on a CRT screen comprises: a memory for storing a complete first image as several pixels in one section of the memory and a complete second image as several other pixels in another section of the memory such that the total number of stored pixels is substantially larger than the number of pixels on the screen; a logic circuit for reading a sequence of the pixels at non-contiguous locations in the first and second images and for transferring them, in the sequence in which they are read, to the screen for display with no frame buffer therebetween; the logic circuit for reading including a module for forming non-contiguous addresses for the pixels in the sequence in which they are read with the address of one word of pixels being formed during the time interval that a previously addressed word of pixels is being displayed on the screen.
