摘要： A method (900) of and wireless communications unit (800) for effecting a handoff from a first Internet Protocol (IP) connection(221) to a second IP connection (331) for a time critical communication is disclosed. The method includes communicating (905) between a first wireless station ( 219) and a second station (331) using the first IP connection and a first IP address (223) for the first wireless station; setting up (907) the second IP connection with a second IP address for the first wireless station, the first IP connection being a primary connection and the second IP connection being a secondary connection; determining (915) that the second IP connection should be the primary connection; and changing (917) the second IP connection to the primary connection by informing the second station that the second IP address is the primary address using stream control transmission protocol (SCTP) messages.

摘要： A method (900) of and apparatus for effecting a handoff from a first Internet Protocol (IP) connection (221) to a second IP connection (331) is disclosed. The method includes: communicating a packet data communication between a first station and a gateway using the first IP connection and a first IP address for the first station, the gateway relaying the packet data communication with a second station; setting up the second IP connection with a second IP address for the first station, the first IP connection being a primary connection and the second IP connection being a secondary connection between the first station and the gateway, determining that the second IP connection should be the primary connection between the first station and the gateway; and changing the second IP connection to the primary connection by informing the gateway that the second IP address is the primary address using stream control transmission protocol (SCTP) messages.
摘要翻译：公开了用于实现从第一网际协议（IP）连接（221）到第二IP连接（331）的切换的方法（900）和装置。该方法包括：使用第一IP连接和第一站的第一IP地址在第一站和网关之间传送分组数据通信，网关中继与第二站的分组数据通信; 利用第一站的第二IP地址建立第二IP连接，第一IP连接是主连接，第二IP连接是第一站和网关之间的次连接，确定第二IP连接应该是第一站与网关之间的主要连接; 以及通过使用流控制传输协议（SCTP）消息通知网关第二IP地址是主地址，将第二IP连接改变为主连接。

摘要： When any remote unit (113-118) desires to create a talk group, it transmits an inbound message to a group call database (112). The inbound message includes the identity of the requesting communication device, and the participants of the talk group. Upon receiving the request, group the call database (112) provides an outbound message to all members of the newly created talk group giving them a chance to opt out of inclusion into the new talk group. The database (112) then creates a database entry with the new talk group and those remote units that positively responded to the outbound message.
摘要翻译：当任何远程单元（113-118）希望创建一个通话组时，它将一个入站消息发送到组呼叫数据库（112）。入站消息包括请求通信设备的身份和通话组的参与者。在接收到请求时，将呼叫数据库（112）分组向新创建的通话组的所有成员提供出站消息，使他们有机会选择不包括在新的通话组中。然后，数据库（112）创建具有新的通话组的数据库条目以及对出站消息有积极响应的那些远程单元。
