摘要： An inter-system handover system for a wireless communication system supports hand-down and hand-up of user equipment (UE) to different radio access technologies, including synchronous and asynchronous systems. Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about neighboring systems (targets) when the UE reception (RX) capability is both inside or outside the reception range of the target. A single RX chain is sufficient, although transitioning between a wireless wide area network (WWAN) to a wireless local area network may (WLAN) may advantageously benefit from simultaneous operation on two Rx chains. Optimized list of neighboring RAT systems (targets) are broadcast from the network, including measurement parameters and reporting instructions. Thereby, UE-driven reporting minimizes latencies. UE reports other-system searches to network only if needed for a handover. In addition, handover requests can be bundled with other-system measurement information, if necessary, for additional efficiencies.

摘要： Techniques for performing handover in order to maintain call continuity for a user equipment (UE) are described. The UE may communicate with a first cell in a radio access network (RAN) for a packet-switched (PS) call, e.g., for Voice-over-Internet Protocol (VoIP) via High-Speed Packet Access (HSPA) in W-CDMA. The UE may send measurement reports to the RAN and may receive trigger from the RAN. The UE may establish a circuit-switched (PS) call with the first cell while the PS call is pending at the first cell. The PS call and the CS call may be for a voice call, and the UE may switch data path for the voice call from the PS call to the CS call and then terminate the PS call. The UE may then perform handover of the CS call from the first cell to a second cell, which may not support VoIP.

摘要： The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network. When supplementary services are invoked involving the device, a protocol is used that signals between the device and a central server that maintains the state information for the supplementary services. In this way, hand-over between the two different types of networks may occur without interrupting supplementary services.

摘要： The disclosure is directed to a mobile communication device that is capable of accessing different types of networks at the same time. The mobile device registers a public ID with a first IP address over a first access network and also registers the same public ID with a different IP address over a second access network. Additional registrations and IP addresses may occur as well. Of particular benefit is that the different registrations are active during at least some concurrent period of time. This allows a user of the mobile device to have improved continuity of service, select preferred access methods, and receive different data services simultaneously.
摘要翻译：本公开涉及能够同时访问不同类型的网络的移动通信设备。移动设备通过第一接入网络注册具有第一IP地址的公共ID，并且在第二接入网络上向不同的IP地址注册相同的公共ID。其他注册和IP地址也可能会发生。特别有益的是，不同的注册在至少一些并发的时间段内是有效的。这允许移动设备的用户具有改进的服务连续性，选择优选的访问方法以及同时接收不同的数据服务。

摘要： A mobile communication system that utilizes multiple access technologies achieves multiple session registrations by deriving a plurality of extended unique device identifications from a specific unique device identification (e.g., private user identification (PIID) stored on a subscriber identity module (SIM)) assigned to a user equipment. Each of the plurality of extended unique device identifications have the benefit of allowing multiple registrations with one or more access networks while allowing a home subscriber system to detect the one unique device identification embedded in the extended unique device identifications for authentication purposes. Thereby, a large population of deployed UEs and access network infrastructure may benefit without replacement by allowing a UE to maintain session continuity when transitioning between access networks, to select a preferred access technology when in overlapping coverage areas without session interruption, or to maintain multiple sessions (e.g., simultaneous Voice over IP (VoIP) and media streaming) with different access networks.
摘要翻译：利用多种接入技术的移动通信系统通过从分配给用户身份识别模块（SIM）的特定唯一设备标识（例如，存储在用户身份模块（SIM）上的专用用户标识（PIID））导出多个扩展唯一设备标识来实现多个会话注册。用户设备。多个扩展唯一设备标识中的每一个具有允许使用一个或多个接入网络进行多次注册的优点，同时允许归属订户系统检测嵌入在扩展唯一设备标识中的一个唯一设备标识用于认证目的。因此，大量部署的UE和接入网络基础设施可以通过允许UE在接入网络之间转换时维持会话连续性而在没有替换的情况下受益，而在没有会话中断的重叠覆盖区域中选择优选的接入技术，或者维护多个会话（例如，同时的IP语音（VoIP）和媒体流）与不同的接入网络。

摘要： The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network. Anchoring of a circuit-switched initiated session is useful when the session is transferred to a packet-switched network. Accordingly, a dynamic anchoring technique is used that relies on the mobile device to determine when, during on ongoing session, a handoff condition exists. The mobile device then sends a trigger signal that initiates the anchoring process.

摘要： In a communication system providing broadcast services in which files for broadcast are accessible by the users. Contents of the broadcast files and the file attributes required to process the broadcast files are separately sent. As arranged, receiving the file attributes ahead of the content files allow more efficient download and processing of the broadcast files.
