    摘要： To reduce a delay between a time that a user of an originating mobile station (MS) requests to set up a Push-To-Talk (PTT) call and the time that the user may begin to speak, a communication system provides a ‘wake up list’ of other mobile stations (MSs) that may be awakened prior to the originating MS requesting to set up a PTT call. To further reduce the delay, the user may begin speaking prior to completion of the call setup. The speech is stored and is conveyed to a called MS when the call is setup. If the call does not get setup or a user of the called MS is not present, the stored speech may be conveyed to the called MS as a voice message. The stored speech, or new speech, may also be used as an announcement of a call instead of the typical “beep” or “chirp.”

    摘要： A user-interface system for entering an alphanumeric string or alphanumeric clusters for identifying information content is presented. The user-interface system has presentation logic for displaying an image of a virtual user alphanumeric interface on a presentation device. The virtual user alphanumeric interface includes an image of an overloaded keypad that has a two dimensional configuration of alphanumeric clusters. Each cluster corresponds to a set of alphanumeric characters. The user-interface system also has cluster selection logic for receiving user actions from an input device (e.g., five-button interface) to provide visual cues to help the user select an alphanumeric cluster and to cause the selected alphanumeric cluster or character from a cluster to be displayed in a display field of the virtual user alphanumeric interface.

    摘要： A method and system are provided for processing a search request received from a user operating a text input device. The search request is directed at identifying a desired item from a set of items. Each of the items of the set of items has one or more associated terms. The method includes receiving a query input from a user directed at identifying the desired item. The query input comprises one or more characters input by the user on the text input device. As each character of the query input is received from the user, a group of items having one or more terms matching the characters received thus far of the query input is dynamically identified. The items in this group of items are ordered based on relevance values of the terms matching the characters and on the number of characters of the query input used in identifying the group of items. Identification of the group of items as ordered is transmitted to the user to be displayed on a device operated by the user.
