Abstract: The present invention provides a method for evaluating a communication link between a first communication site and a second communication site. The first and second communication sites increment a sent counter and reset a received counter upon sending a message to the other communication site. Each communication site also increments a received counter and reset a sent counter upon receiving a message from the other communication site. When the sent counter exceeds a sent threshold, the communication system site sends an alert that the communication link is down. When the received counter exceeds a predetermined percentage of the other communication site's sent counter, the site sends a message to the other communication site to let the other communication system site know that it is still receiving messages.

Abstract translation: 本发明提供了一种用于评估第一通信站点和第二通信站点之间的通信链路的方法。 第一和第二通信站点在发送消息到其他通信站点时增加发送的计数器并重置接收到的计数器。 每个通信站点也会增加收到的计数器，并在从其他通信站点接收到消息时重置发送的计数器。 当发送的计数器超过发送的阈值时，通信系统站点发送通知链路关闭的警报。 当所接收的计数器超过其他通信站点的发送计数器的预定百分比时，站点向另一个通信站点发送消息，让另一个通信系统站点知道它仍在接收消息。

Abstract: A communication network (100) includes a first server (124) and a second server, such as any of the servers (121-23), connected via a common network (101). First server (124) owns a record data (180) associated with at least one process running for serving a client device (174.) The second server keeps a copy of the record data. First server (124) performs a Hashing function over record data (180) to produce a first Hash value. The second server similarly performs the same or similar Hashing function over the copy of the record data to produce a second Hash value. First server (124) sends the first Hash value to the second server for comparison. If the first Hash value fails to match to the second Hash value, a latest copy of the record data (180) is sent from first server (124) to the second server upon request.

Abstract translation: 通信网络（100）包括经由公共网络（101）连接的第一服务器（124）和诸如服务器（121-23）中的任一个的第二服务器。 第一服务器（124）拥有与至少一个运行用于服务客户端设备的进程相关联的记录数据（180）。第二服务器保存记录数据的副本。 第一服务器（124）对记录数据（180）执行哈希函数以产生第一哈希值。 第二个服务器类似地在记录数据的副本上执行相同或相似的哈希函数，以产生第二个哈希值。 第一服务器（124）将第一哈希值发送到第二服务器进行比较。 如果第一哈希值不匹配到第二哈希值，则根据请求将记录数据（180）的最新副本从第一服务器（124）发送到第二服务器。

Abstract: A method of switching a call to a multipoint conference call includes sending a message (201) from a first terminal (105-T1) to a gatekeeper (102) which provides address translation and control access to a shared network medium (101). The call is initially established as a point to point communication between first terminal (101) and a second terminal (105-TN) over shared network medium (101) while complying with H.323 standard. Message (201) contains a request for the multipoint conference call. The method furthermore includes selecting a multipoint control unit (104) connected to shared network medium (101) to allocate resources for the multipoint conference call, and then switching the call to the multipoint conference call via the allocated resources. Thereby, the initial call is switched to a multipoint conference call without interrupting the initial call.

Abstract translation: 将呼叫切换到多点会议呼叫的方法包括从第一终端（105-T1）发送消息（201）到提供对共享网络媒体（101）的地址转换和控制访问的网守（102）。 呼叫最初被建立为在符合H.323标准的同时在共享网络介质（101）之间的第一终端（101）和第二终端（105-TN）之间的点对点通信。 消息（201）包含对多点电话会议的请求。 该方法还包括选择连接到共享网络介质（101）的多点控制单元（104）以分配用于多点会议呼叫的资源，然后经由所分配的资源将呼叫切换到多点会议呼叫。 因此，初始呼叫被切换到多点电话会议而不中断初始呼叫。

Abstract: A method and apparatus for data transmission is provided herein. In accordance with the preferred embodiment of the present invention a loss-ratio estimator (105) estimates a current loss (L) for a communication channel (108). Once the actual loss for the channel is known, a generator (104) compares the actual loss (L) to a target loss (T). A retransmission control parameter (R) is then adjusted by the generator (104) and output to a transmitter 103 where it is used to control the retransmission behavior and to determine when to abort a bad frame. When a bad frame is aborted, transmitter 103 indicates the abortion to a receiving device (102). A receiver then utilizes the indication to stop reporting the bad frame in all subsequent ACK/NAKs.

Abstract: Methods and systems are provided for routing callers to agents in a call-center routing environment. An exemplary method includes identifying caller data for a caller in a queue of callers, and jumping or moving the caller to a different position within the queue based on the caller data. The caller data may include one or both of demographic data and psychographic data. The caller can be jumped forward or backward in the queue relative to at least one other caller. Jumping the caller may further be based on comparing the caller data with agent data via a pattern matching algorithm and/or computer model for predicting a caller-agent pair outcome. Additionally, if a caller is held beyond a hold threshold (e.g., a time, “cost” function, or the like) the caller may be routed to the next available agent.

Abstract: An RTP payload header (408) is compressed by utilizing a codebook (514) that holds one or more indexable payload header variations and sending it to a receiving device (504). An RTP packet (400) that includes the payload header (408) with information pertaining to the packet is generated by a sending device (502) and the codebook is searched for the payload header information. If the information is found, the payload header (408) is replaced with a short index in the codebook (514). At the receiving device (504) the index is used to retrieve a payload header variation that corresponds to the index and the variation is placed back into the payload header (408) to uncompress the header.

Abstract translation: 通过利用保存一个或多个可索引有效载荷报头变化并将其发送到接收设备（504）的码本（514）来压缩RTP有效载荷报头（408）。 通过发送装置（502）生成包含具有与分组有关的信息的有效载荷报头（408）的RTP分组（400），并且对码本进行有效负载报头信息的搜索。 如果找到信息，则在码本（514）中用短索引代替有效载荷报头（408）。 在接收设备（504）处，索引用于检索对应于索引的有效载荷报头变化，并且将变化放回到有效载荷报头（408）中以解压缩报头。

Abstract: In the present technique of streaming a main media stream that has been requested, an anti-shadow stream (36) that represents a backup copy of the main media stream (24) is sent along with an output media stream (34) that represents an output copy of the main media stream. The content of the anti-shadow stream (36) is preferably forward-shifted in time from the output media stream (34) so as to provide replacement of loss data of the output stream. Put differently, sequenced data frames of the output stream (34) are delayed by order compared to that of the anti-shadow stream (36).

Abstract translation: 在现有的已经请求的主媒体流的流技术中，代表主媒体流（24）的备份副本的反影子流（36）与一个输出媒体流（34）一起发送，该输出媒体流 主要媒体流的输出副本。 反阴影流（36）的内容优选地在时间上从输出媒体流（34）向前移位，以便提供输出流的丢失数据的替换。 换句话说，与反阴影流（36）相比，输出流（34）的顺序数据帧被延迟了一个顺序。

Abstract: Methods and systems are provided for routing callers to agents in a call-center routing environment. An exemplary method includes pooling incoming callers, and causing a caller from the pool of callers to be routed. The caller may be routed from the pool of callers to an agent, placed in another pool of callers, or placed in a queue of callers. The caller data may include demographic or psychographic data. The caller may be routed from the pool of callers based on comparing the caller data with agent data associated with an agent via a pattern matching algorithm and/or computer model for predicting a caller-agent pair outcome. Additionally, if a caller is held beyond a hold threshold (e.g., a time, “cost” function, or the like) the caller may be routed to the next available agent.

Abstract: Various embodiments are described to enable improved inter-network/inter-technology handover of mobile devices. A network device (131, 132) collects dynamic information corresponding to mobile devices (101, 102), such as wireless measurement information at the device's location, and/or information corresponding to wireless network nodes (121-124), such loading levels/loading distributions. The network device then sends some or all of the dynamic information collected and/or statistical information generated from the dynamic information collected to a neighboring network information server (150) for access by other communication networks. By maintaining dynamic and/or statistical information in a neighboring network information server, such information can be made available to all the communication networks in a given region. One potential benefit to making this information available is improved inter-network handoff decision-making.
