摘要： In a network comprising a plurality of channels, at least two channels are operating at different frequencies. The fixed network equipment (FNE; 124, 126) identifies a plurality of channels present at a serving site and classifies each channel into one of a plurality of bandwidth groups. All the channels in a given bandwidth group have common roaming characteristics. The FNE periodically broadcasts information relating to at least one channel in each bandwidth group present at the serving site. The FNE further identifies least one channel present at an adjacent site. Each channel present at the adjacent site is also classified in one of the plurality of bandwidth groups. The FNE broadcasts information on loading for each bandwidth group present at the adjacent site.

摘要： Requesting (transmitting) subscriber units may immediately begin transmitting an information signal over an assigned communication channel. Receiving subscriber units immediately unmute their speakers and monitor the assigned communication channel and attempt to detect a code, which indicates that they are monitoring the correct communication channel. At the central station (repeater), the information signal may be immediately repeated, unless an interference signal is present. In this way, the information signal may be rapidly disseminated (repeated) to improve subscriber access time, while providing assurance that the receiving subscribers will not receive a noise signal or the interference signal.
摘要翻译：请求（发送）用户单元可以立即开始通过分配的通信信道发送信息信号。接收订户单元立即取消静音其扬声器并监视分配的通信信道，并尝试检测代码，这表示它们正在监视正确的通信信道。在中央站（中继站），信息信号可以立即重复，除非存在干扰信号。以这种方式，可以快速地传播（重复）信息信号以改善用户接入时间，同时保证接收用户不会接收到噪声信号或干扰信号。

摘要： An apparatus and method for issuing busy call-backs (146) on the voice channel to busied communication units (209,211) on a trunked radio communication system (200) is disclosed. This is accomplished, in part, by issuing a busy signal (104), via a control resource (203), to a communication unit when a requested communication resource is unavailable. Additionally, the radio communication unit (209,211) is capable of receiving the busy signal via the control resource (213) and participating in a second communication while in a busied state. The resource controller (201) is capable of allowing the busied communication unit (209,211) to participate in a second communication on a second communication resource (215) and issuing the call-back signal during the second communication.

摘要： Application service is provided for a subscriber unit (SU), employing a first protocol, in a communication network employing a second protocol. The method includes receiving a CAI OTAR message from the SU. The CAI OTAR message includes at least a key management message (KMM) and a CAI header of the SU. The method then includes determining that the first protocol employed by the SU is different from the second protocol associated with the communication network based on the received CAI OTAR message. The method further includes creating a key management message (KMM) preamble, associated with the second protocol, based on at least one of the CAI header and configuration information of the SU, and creating a data link independent (DLI) OTAR message associated with the second protocol. The DLI OTAR message includes the received KMM. The method finally includes encapsulating the DLI OTAR message with the created KMM preamble, and sending the encapsulated DLI OTAR message to a key management facility (KMF) unit operating at a second protocol.

摘要： The application discloses a method and apparatus for providing interoperability for a mobile subscriber unit (MSU), employing a first protocol e.g., SCEP, with a packet-data subsystem operating at a second protocol e.g., SNDCP. The method includes determining that the first protocol employed by the MSU is different from the second protocol operated by the packet data subsystem. The method then includes creating a context information for the MSU when the determined first protocol is different from the second protocol. Further, the method includes determining a header associated with the second protocol based on the created context information and then receiving at least one data packet associated with the first protocol from the MSU. The method then encapsulates the at least one data packet with the determined header associated with the second protocol. The method then transmits the at least one encapsulated data packet to the communication network through a context manager.

摘要： A subscriber (100) transmits data on a first data channel. While transmitting, the subscriber tracks the number of collisions it experiences on the first data channel (206). When the number of collisions reaches a threshold value, the subscriber transmits a reassignment request to move to a new data channel. Upon receipt of the reassignment request, a central processor (102) assumes that the first data channel is loaded. The central processor will then compare an incoming data rate to a value to determine if the first data channel is actually loaded, wherein the incoming data rate is measured by the central processor at the time the subscriber requested reassignment.
摘要翻译：订户（100）在第一数据信道上发送数据。在发送时，用户跟踪其在第一数据信道（206）上经历的冲突的数量。当冲突次数达到阈值时，用户发送重新分配请求以移动到新的数据信道。在接收到重新分配请求时，中央处理器（102）假设加载了第一数据信道。然后，中央处理器将输入数据速率与一个值进行比较，以确定第一个数据通道是否实际加载，其中输入数据速率由中央处理器在用户请求重新分配时测量。

摘要： Methods are disclosed for providing requested access, network-initiated access and autonomous access to communication resources (101-105) by wireless communication unit(s) (112, 114), and for controlling the different types of access using access control identifier(s) assigned to the devices. Requested access requires a communication unit to send a call request (302) to a communication resource controller (106). The request (302) includes at least an identification of the communication unit and an access control identifier associated with the communication unit. Network-initiated access comprises a communication resource controller or other fixed network equipment sending a page request (502) to the communication unit which responds with a page response message (504) including the identification of the communication unit and an access control identifier. The communication resource controller (106) determines, based on the access control identifier, whether a communication resource is available to support the request. Autonomous access comprises the communication unit (112, 114) receiving a service advertisement message (402) identifying a communication resource and one or more access control identifiers associated with the communication resource. The communication unit determines its eligibility for autonomous access based on the service advertisement message. The service advertisement message may be used to indicate an availability status of communication resources as available for autonomous access or requested access or not available for selected user groups.

摘要： A multi-carrier receiver radio monitors frequency channels associated with at least one talkgroup to which a multi-carrier receiver radio subscribes. The talkgroup is associated with a set of frequency channels that may carry group call activity. The radio monitors each frequency channel of the set of frequency channels associated with the talkgroup for group call activity. During monitoring, when a new call is detected on one frequency channel of the set of frequency channels associated with the talkgroup, the radio joins the new call. While joined to the new call, the radio continues to monitor the set of frequency channels associated with the talkgroup for additional transmissions to the talkgroup and to monitor a set of frequency channels associated with another talkgroup to which the multi-carrier receiver radio also subscribes for group call activity on the other talkgroup.
