    Abstract: Systems, methods and communication nodes according to exemplary embodiments provide for an IMS node to replicate call content for lawful call interception in packet cable networks. A CSCF node sends a command to an SBC node to perform call content replication for an identified call to be intercepted. The SBC node forwards the replicated call content to a delivery function, which in turn forwards the replicated call content to the appropriate law enforcement agency.

    Abstract: A method of improving cell change procedures within a General Packet Radio Service (GPRS) network to reduce the handover interruption time while keeping the delays to affordable values for real-time payload services. The data stream interruption is reduced at the air interface level and the core network level. Improvements at the air interface are achieved by reducing the system information retrieval time and pre-allocating the radio resources prior to the MS accessing the new cell. Improvements within the core network are achieved by shortening the inter-SGSN Routing Area Update interruption interval and implementing low latency delay-sensitive requirements and shaping packet traffic for premium traffic.

    Abstract translation: 一种在通用分组无线业务（GPRS）网络内改善小区改变过程的方法，以减少切换中断时间，同时将延迟保持为用于实时有效负载业务的经济价值。 数据流中断在空中接口级别和核心网级别减少。 通过减少系统信息检索时间并在MS接入新小区之前预先分配无线电资源来实现空中接口的改进。 通过缩短SGSN间路由区域更新中断时间间隔，实现低延迟延迟敏感要求，并优化流量，实现核心网络内部的改善。

    Abstract: A Radio Access Network (RAN) (10) and method for rapid handover of a mobile station between a Source Radio Network Controller (SRNC) (12) and a Target Radio Network Controller (TRNC) (21) in the RAN. A mobile station (16) initially served by the SRNC accesses an Enhanced General Packet Radio Service (EGPRS) network (27) through the RAN for conducting a packet-switched call. When handover to the TRNC is required, the SRNC notifies the TRNC that relocation of the mobile station to the TRNC is requested. The TRNC reserves radio resources required to serve the mobile station in the TRNC, and notifies the SRNC that relocation is approved. An Iux interface (11) may be established between the SRNC and the TRNC for direct communication of control signaling. Alternatively, the control signaling between the SRNC and the TRNC may pass through the EGPRS network. The EGPRS begins bi-casting Packet Data Units (PDUs) (44) to both the SRNC and the TRNC until notified by the TRNC that the handover is complete (45). The mobile station is then handed over to the TRNC, and the EGPRS network is notified by the TRNC that the handover is complete. With the Iux interface (11), control signaling that is specific to the RAN does not have to be passed through the EGPRS network.

    Abstract translation: 一种无线电接入网络（RAN）（10）和用于在RAN中的源无线电网络控制器（SRNC）（12）和目标无线电网络控制器（TRNC）（21）之间快速切换移动站的方法。 最初由SRNC服务的移动站（16）通过RAN访问增强通用分组无线服务（EGPRS）网络（27），以进行分组交换呼叫。 当需要切换到TRNC时，SRNC通知TRNC请求将移动台重新定位到TRNC。 TRNC保留为TRNC服务移动台所需的无线电资源，并通知SRNC移位被批准。 可以在SRNC和TRNC之间建立IUS接口（11），用于控制信令的直接通信。 或者，SRNC和TRNC之间的控制信令可以通过EGPRS网络。 EGPRS开始向SRNC和TRNC双向分组数据单元（PDU）（44），直到TRNC通知切换完成（45）。 然后移动台切换到TRNC，并且TRNC通知EGPRS网络完成切换。 使用Iux接口（11），RAN特有的控制信令不必通过EGPRS网络传递。

    Abstract: A RATIO ACCESS NETWORK (RAN) AND METHOD FOR RAPID HANDOVER OF A MOBILE STATION BETWEEN A SOURCE RADIO NETWORK CONTROLLER (SRNC) AND A TARGET RADIO NETWORK CONTROLLER (TRNC) IN THE RAN. A MOBILE STATION INITIALLY SERVED BY THE SRNC ACCESSES AN ENHANCED GENERAL PACKET RADIO SERVICE (EGPRS) NETWORK THROUGH THE RAN FOR CONDUCTING A PACKET-SWITCHED CALL. WHEN HANDOVER TO THE TRNC IS REQUIRED, THE SRNC NOTIFIES THE TRNC THAT RELOCATION OF THE MOBILE STATION TO THE TRNC IS REQUESTED. THE TRNC RESERVES RADIO RESOURCES REQUIRED TO SERVE THE MOBILE STATION IN THE TRNC, AND NOTIFIES THE SRNC THAT RELOCATION IS APPROVED. AN IUX INTERFACE MAY BE ESTABLISHED BETWEEN THE SRNC AND THE TRNC FOR DIRECT COMMUNICATION OF CONTROL SIGNALING. ALTERNATIVELY, THE CONTROL SIGNALING BETWEEN THE SRNC AND THE TRNC MAY PASS THROUGH THE EGPRS NETWORK. THE EGPRS BEGINS BI-CASTING PACKET DATA UNITS (PDUs) TO BOTH THE SRNC AND THE TRNC UNTIL NOTIFIED BY THE TRNC THAT THE HANDOVER IS COMPLETE. THE MOBILE STATION IS THEN HANDED OVER TO THE TRNC, AND THE EGPRS NETWORK IS NOTIFIED BY THE TRNC THAT TH HANDOVER IS COMPLETE. WITH THE IUX INTERFACE, CONTROL SIGNALING THAT IS SPECIFIC TO THE RAN DOES NOT HAVE TO BE PASSED THROUGH THE EGPRS NETWORK.FIGURE 3
