摘要： A wireless communication device accesses a scan list that includes a plurality of scan members sorted at least by receive frequency and attempts to detect whether a call of interest exists on a receive frequency by performing a group scan for a group of scan members that are marked scan undone and that have the same corresponding receive frequency, wherein the group includes a first scan member and at least one other scan member. The group scan includes inspecting the receive frequency to obtain inspection results; using the inspection results to determine that there is no signal on the receive frequency having signal attributes that match a set of attributes for the first scan member; and using the inspection results to evaluate at least one of the other scan members in the group to determine whether there is a corresponding signal of interest on the receive frequency.

摘要： Disclosed is a method and system for interrupting a transmitting subscriber where the transmitting subscriber communicates on a forward channel of a wireless communications system while listening to a reverse channel for reverse channel signaling. The transmitting subscriber receives reverse channel signaling on the reverse channel from a second subscriber, wherein the message is received either directly from the second subscriber or through at least one base radio and terminates the communication on the forward channel in response to the received reverse channel signaling.

摘要： A new group call request is received from a subscriber station at a rest channel repeater at a first network location. Corresponding new group call notifications are then transmitted to each of the other network locations over a wide area network to a current one of the repeaters acting as a rest channel repeater at each of the other network locations. Subsequently, an identity of a traffic channel repeater hosting the new call is received from each of the respective other network locations. An over-the-air notification is transmitted to other subscriber stations at the first network location identifying one of the first rest channel and another available channel as a channel for the new group call. Data received from the first subscriber station is then forwarded to each of the identified traffic channel repeaters at each of the other network locations via the wide area network.

摘要： A device detects a first signal on a channel that is one of a plurality of channels arranged in a first order on a list, with each channel being associated with a different site in a multi-site communication system. Upon detecting the first signal, the device attempts to measure and record signal strength of a signal at each channel on the list based on the first order beginning with the detected first signal, and selects as a home site the site associated with the channel having the signal with the highest recorded signal strength. The device rearranges the channels on the list into a second order based on the recorded signal strengths with the home site channel at the top. If necessary, the radio attempts to awaken its repeaters one after another based on the second order until a repeater is found to transmit a signal.

摘要： To perform a channel inspection, a wireless communication device: monitors a common announcement channel (CACH) until detecting that a first set of identified parameters associated with a signal on a first channel matches a second set of known parameters for the first channel; performs an inspection on the first channel to determine whether the signal is of interest; and when the signal is not of interest, marks the first channel to prevent another inspection from being performed on the first channel until after the channel mark is removed. The communication device then leaves the first channel and continues to monitor the CACH for a change in the first set of identified parameters or an indication of an idle first channel, wherein the communication device removes the channel mark on the first channel.

摘要： 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 hosts a first channel that is currently serving as a rest channel. The channel that is currently serving as the rest channel is monitored by subscriber units that are idle in the system. When the repeater determines to select a second channel to serve as the rest channel, it determines whether there is at least one eligible channel to serve as the rest channel. If there is at least one eligible channel in the system, the repeater may select the second channel to serve as the rest channel from one of the eligible channels.

摘要： To perform channel inspection, a wireless communication device conducts a full inspection on a first channel carrying a first signal that includes: determining a location of a first synchronization message; and determining whether the first signal is of interest. Upon determining that the first signal is not of interest, the first channel is marked, wherein the marking includes remembering the location of the first synchronization message. The device leaves the first channel and determines an expected location of a second synchronization message on the first channel based on the location of the first synchronization message. Upon returning to the first channel which carries a second signal, the communication device conduct a partial inspection that includes: detecting whether the second synchronization message is present at the expected location, wherein the presence of the second synchronization message indicates that the second signal is not of interest.

摘要： A system and method for pausing communications from a transmitting radio for a certain period of time in order to allow transmission of other messages. When a first radio determines that a message needs to be transmitted either to a second radio or the transmitting radio, the first radio determines whether there are any available forward channels to transmit the call. If no forward channel is available, the first radio determines a period of time required to transmit the message and sends, on a reverse channel, a “request to pause” signal to the transmitting radio identifying that period of time. Upon receiving the “request to pause” signal, the transmitting radio ceases transmission on the forward channel for the specified period of time, during which time the first radio transmits the message.

摘要： A system and method for managing forward channel access using a reverse channel in a wireless communication system is disclosed. A repeater receives requests on a reverse channel to access a forward channel. Each request includes a priority. The repeater selects a request based upon the priority. The repeater then allows access to the forward channel for a transmission based upon the selected request.

摘要： In a peer to peer trunked radio network having a plurality of network locations, each network location includes a plurality of repeaters and a dynamically selected at least temporarily act as a rest channel repeater at each network location. A first repeater at the first network location may determine a first timing at which to broadcast an intra-site beacon and a second timing at which to broadcast an inter-site roaming beacon, the intra-site beacon including at least a rest channel identifier indicating a rest channel of the first network location and the inter-site roaming beacon including at least remote rest channel repeater information identifying a second repeater at a second network location that is currently acting as a rest channel repeater at the second network location. The first repeater may then broadcast the intra-site beacon at the first timing and the inter-site roaming beacon at the second timing.
