Abstract: A method (200) and an apparatus (700) for a wireless communication network (102) for providing a broadcast message to a group of wireless communication devices (104, 106, 108) engaged in a push-to-talk (“PTT”) communication are provided. The wireless communication network (102) receives (204) broadcast information from a priority entity (118), processes (206) the broadcast information into the broadcast message, preempts (208) floor control of the PTT communication of the group of wireless communication devices, take a floor control (210) of the PTT communication, and transmits the broadcast message to all (212) or to a target group (602) of wireless communication devices.

Abstract: A method (200) and an apparatus (106) for a wireless communication device for receiving an emergency broadcast message are provided. The wireless communication device (106) monitors (204) incoming broadcast messages, and determines (206) whether the incoming broadcast messages include the emergency broadcast message. If the emergency broadcast message is included, then the wireless communication device (106) overrides (208) a settable broadcast service reception preference, and receives (210) the emergency broadcast message. The wireless communication device (106) then transmits (212) an acknowledgment of receiving the emergency broadcast message, and communicates (214) the reception of the emergency broadcast message.

Abstract: A method (200) and an apparatus (106) for a communication device for conveying information contained in an emergency broadcast message to an external device (110) are provided. The communication device (106) monitors (204) incoming broadcast messages in at least one of a broadcast mode and a multicast mode of a Multimedia Broadcast and Multimedia Service, and determines (206) whether the incoming broadcast messages include the emergency broadcast message. If the emergency broadcast message is included, then the communication device (106) receives (208) the emergency broadcast message, transmits (210) an acknowledgment of receiving the emergency broadcast message, and transmits (212) the information (108) contained in the emergency broadcast message to the external device (110).

Abstract: Briefly, according to the invention, a tilt switch 30 comprises a body 20 including a substantially conical cavity. The substantially conical cavity has at least a portion 24 which is electrically conductive. The tilt switch further has an electrical contact 32 spaced from the conductive portion 24 of the cavity. Finally, a conductive ball 34 located within the cavity selectively interconnects the electrical contact 32 and the conductive portion 24 of the cavity when the tilt switch 30 is tilted.In another aspect of the invention, a jitter switch 40 comprises a body 50 including a substantially concave shaped cavity. The substantially concave cavity has a curved bottom surface having a conductive portion (48) thereon and a sidewall having a separate conductive portion (44) thereon. A conductive ball 46 within the cavity intermittently interconnects the conductive portion of the bottom surface 48 with the conductive portion on the sidewall 44 when the jitter switch 40 is in motion.
