    摘要： A keypad device for a mobile telephone or other device utilizing a keypad or keyboard is comprised of a flexible substrate and a keypad cover. The flexible substrate includes a plurality of keys affixed to the surface as well as a plurality first conductive strips associated with each key. The keypad cover is attached to the flexible substrate. The keypad cover typically includes holes that permit the plurality of keys to protrude through the keypad cover. In addition, the keypad cover further includes a plurality of second conductive strips that selectively contact a corresponding first conductive strip on the flexible substrate. The plurality of first conductive strips is coupled to ground and the plurality of second conductive strips is coupled to logic circuitry. Or, in another embodiment, both sets of conductive strips are coupled with the logic circuitry. The default position of the keypad device has each of the first conductive strips in contact with each of the corresponding second conductive strips. This creates a short circuit condition that prevents key signals from being received by the logic circuitry. When a particular key is depressed to the point where the first conductive strip associated with that particular key is separated from the second conductive strip corresponding to the first conductive strip, the short circuit condition is removed. This allows a signal to be transmitted to and processed by the logic circuitry indicating that a particular key has been selected.

    摘要翻译： 用于移动电话或使用键盘或键盘的其他设备的键盘装置包括柔性基板和键盘盖。 柔性基板包括固定到表面的多个键以及与每个键相关联的多个第一导电条。 键盘盖连接到柔性基板上。 键盘盖通常包括允许多个键突出通过键盘盖的孔。 此外，键盘盖还包括多个第二导电条，其选择性地接触柔性基板上相应的第一导电条。 多个第一导电条耦合到地，并且多个第二导电条耦合到逻辑电路。 或者，在另一个实施例中，两组导电条与逻辑电路耦合。 键盘装置的默认位置使每个第一导电条与每个相应的第二导电条接触。 这产生了防止键信号被逻辑电路接收的短路状态。 当特定键被压下到与该特定键相关联的第一导电带与对应于第一导电带的第二导电带分离的点时，消除短路状态。 这允许将信号发送到逻辑电路并由逻辑电路进行处理，指示已经选择了特定的键。

    摘要： A method for reassigning mobile stations a new phase within a channel is disclosed. In a communication system, a plurality of mobile stations attempt to communicate on a limited number of channels. The invention first uses a general allocation method to approximately evenly distribute the mobile stations on the available channels. After a mobile station begins active communication on the system, a second allocation method is used to change the phase of some mobile stations on a channel which has become heavily loaded. In addition, a message can also be sent to mobile stations assigned to but not yet actively communicating on the heavily loaded channel indicating that the mobile stations should change to a new channel.

    摘要： A method and device are provided for storing and maintaining parameters associated with activities relating to a first channel while a mobile station is camped on or uses a second channel. More specifically, when a parameter indicates that activities are to be executed, the mobile station returns to the first channel to execute the actions associated with the parameter. For instance, parameters associated with a DCCH may be stored when the mobile station moves from the DCCH to a packet data channel (PDCH). When a parameter indicates that activities are to be executed, the mobile station may then return to the DCCH from the PDCH and execute the actions associated with the parameter. Since the mobile station returns to the DCCH for the actions rather than staying on the PDCH, the mobile station is activated from a system perspective, on both channels.

    摘要： A method and device are provided for controlling an activity mode of a mobile station after the system has originated or terminated a transaction with the mobile station. The activity mode corresponds to whether the mobile station stays "awake" or goes into a sleep mode, which must be made known to the system. If the mobile station does not immediately go to the sleep mode, the base station can expect the mobile station to be reading all slots. If the mobile station is in the sleep mode, the mobile station only reads its assigned paging slots. The mobile station may not go to the sleep mode until a selected amount of activity time has expired; during the activity time, the mobile station continues to read all slots. As a result, the mobile station can immediately receive packets, thereby saving set-up time which increases the response time of the mobile station.

    摘要： A method and apparatus is provided for extending the battery life of a cellular radiotelephone. A cellular radiotelephone is conditioned to operate in a pager-only mode wherein the radiotelephone may receive short messages from a base station while conserving battery life by cyclically adopting a deep-sleep state. The base station is notified by the radiotelephone before the radiotelephone enters the deep-sleep state that the radiotelephone is unable to receive messages. After a period of time, the radiotelephone wakes-up, re-establishes contact with the base station and notifies the base station that the radiotelephone is ready to receive messages. After receipt of any messages the radiotelephone repeats the process.
