摘要： Disclosed is a method for encrypted communications. A first IPsec endpoint selects a security association (SA) from a security association database (SAD) by using a selector and then extracts an indexing parameter from SA. The indexing parameter is used to determine an active key location from a key storage database (KSD). Data packets are then encrypted using a key from the active key location. The first IPsec endpoint also forms a security parameter index (SPI) in a header of the data packet by using a keyID from the active key location and transmits the encrypted data packet with the header indicating the SPI to a second IPsec endpoint.

摘要： The present invention discloses, in a two-way radio frequency (RF) communications system having at least one repeater, a plurality of channels, and a plurality of subscriber units, a repeater receives a message that identifies a channel that is selected to serve as a rest channel for the system. The channel that is currently serving as the rest channel for the system is monitored by subscriber units that are idle in the system. If the repeater determines that the channel selected to serve as the rest channel is hosted by the repeater, the repeater periodically transmits an identity of the channel as the channel currently serving as the rest channel on at least the channel.

摘要： Within a two way radio frequency communication system, a repeater transmits an identity of a rest channel when transmitting during an active communication call on a channel other than the rest channel. A subscriber unit communicating within the active communication, receives the identity of the rest channel, leaves the active communication; and initiates a new communication on the rest channel.
