Abstract: An instant message (IM) proxy according to the present invention is capable of maintaining the availability status of a mobile subscriber even when the mobile subscriber is roaming or temporarily out of a mobile network coverage area, and even after the IM proxy unsuccessfully attempts to send an instant message to the mobile subscriber. Messages will continue to be re-sent to the mobile subscriber in the near-real time manner characteristic of a typical instant message system until IM parameters programmed into a retry counter and/or the timer located at the proxy are exceeded and the IM proxy drops the message. In addition, the IM proxy of the present invention is capable of bundling instant messages intended for the mobile subscriber to minimize mobile system overhead connection costs while at the same time minimizing IM system latency

Abstract: An agent (100) is associated with each of a plurality of devices (201-204) for arbitrating between a talk stream generated by the device and a listen stream intended for the device and generated by another device on a network (210). In the agent a nullTalk Modenull (300) is defined in which the agent passes the talk stream from the device to other devices participating in the conference while blocking all listen streams intended for the device, and a nullListen Modenull (400) is defined in which the agent blocks the talk stream of the device from the network and passes a single listen stream from the network to the device. The agent makes a decision to enter one of the Talk Mode and the Listen Mode, wherein the decision is based upon a presence of at least one of the talk stream and the listen stream, and wherein the decision is further based upon a comparison of source identifiers of the talk and listen streams when required to resolve a conflict.

Abstract translation: 代理（100）与多个设备（201-204）中的每一个相关联，用于在由设备生成的通话流和用于设备并由网络上的另一设备（210）生成的监听流之间进行仲裁。 在代理中，定义了“通话模式”（300），其中代理将来自设备的通话流传递到参与会议的其他设备，同时阻止针对设备的所有监听流，以及“监听模式”（400） 其中代理阻止来自网络的设备的通话流，并将单个监听流从网络传递到设备。 代理决定进入通话模式和听音模式之一，其中所述决定基于通话流和听音流中的至少一个的存在，并且其中所述决定还基于源的比较 当需要解决冲突时，通话和侦听流的标识符。

Abstract: 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 (either acting as an application level gateway or as and endpoint for an SCTP tunnel) 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, the first and the second IP connection existing concurrently; 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, wherein the packet data communication is immediately switched over to the second IP connection.

Abstract: To facilitate fair access to a channel, a controller (200) adds a member-specific channel-access delay, including adding at least one of a first member-specific delay (308) to a transmission of a free channel indication from the controller to a member (118-128) after the channel becomes free; and a second member-specific delay (314) before processing a request to talk received by the controller from the member. The controller selects (302) the member-specific channel-access delay such that a time required for the member to gain access to the channel after the channel becomes free is essentially equal to the time required for any other participating member to gain access to the channel after the channel becomes free.
