TL;DR: In this article, a mobile station monitors the signal strength of pilots and reports the measured signal strength to a system controller via the base station through which it is communicating and terminates communication through the corresponding base station while communications through the other base station or base stations continue.
Abstract: In a code division multiple access (CDMA) spread spectrum cellular communication system in which a mobile station user communicates with another system user via at least one base station, wherein each base station transmits a common pilot signal of a different code phase with respect to other base stations in said system, a method for directing communications between said mobile station user and said base stations. The mobile station monitors the signal strength of pilots and reports the measured signal strength to a system controller via the base station through which it is communicating. Command messages from the system controller to a new base station and the mobiles station establishes communication through the new base station in addition to the communication through the current base station. When the mobile station detects the falling below a predetermined level of the signal strength of a pilot corresponding to at least one of the base stations through which the mobile station is communicating, the mobile station reports the measured signal strength indicative of the corresponding base station to the system controller via the base stations through which it is communicating. Command messages from the system controller to the identified base station and the mobiles station terminates communication through the corresponding base station while communications through the other base station or base stations continue.

TL;DR: In this article, the electronic programming guide is displayed by a subscriber terminal at the subscriber's location, and a subscriber can select programs for watching or recording from the electronic program guide.
Abstract: A subscription television system is provided that transmits a plurality of television signals to a plurality of subscribers. The television signals include pay-per-view programs (purchased by feature) or near-video-on-demand programs (purchased for a period of time for unlimited viewing) that are provided only to subscribers that purchase the programs. Data (16) representing an electronic programming guide is also transmitted. The electronic programming guide can be displayed by a subscriber terminal at the subscriber's location. The electronic programming guide is a grid (Fig. 4A and 4B) listing television programs by date, time and channel. A subscriber can select programs for watching or recording from the electronic program guide. Moreover, the subscriber can purchase pay-per-view or near-video-on-demand programs from the electronic programming guide.
