Abstract: In a multi-layer telecommunications system which includes an application layer and a transport layer, differing transport technologies are interworked without terminating the application layer signaling or without involving a technology interworking in the control plane of the application layer (e.g., without interworking in the application signaling). In various illustrated embodiments, the application layer is a radio network layer of a wireless telecommunications system. In at least some embodiments of the present invention a transport layer interworking function is situated on an interface between two nodes (26, N) of the radio access network (RAN). The interworking function can be located in a separate node, or within one of the Nodes having both ATM and internet protocol (IP) interfaces. There are numerous modes of implementing the interworking of the present invention, regardless of which interface is affected (e.g., an Iur interface, an Iu interface, or an Iub interface). A first interworking mode involves interworking with q.aal2 signaling. There are various ways or options of implementing the interworking with q.aal2 signaling. A first such example option is to use an IP specific signaling protocol over the IP network. A second example option is to use q.aal2 signaling over the IP network to/from the IP node. In one of its aspects, the present invention also provides an optimization feature in the event that nodes on both sides of the interface (Iu interface, Iur interface, or Iub interface) are IP-connected nodes. Another interworking mode involves obtaining address and binding identifier parameters to be included in application signaling messages by consulting a transport layer interworking gateway. Yet another mode of implementing interworking for the present invention involves tunneling.

Abstract: A call recovery method uses a multiple access forward call recovery channel to perform simultaneous rescues for multiple mobile stations. Rescue messages, such as handoff direction messages, for different mobile stations are multiplexed onto the call recovery channel for transmission to mobile stations in need of rescue.

Abstract: A method and apparatus for link supervision determines whether a link signal is present or absent by measuring received energy for that signal. If the measured energy for the signal does not meet a defined energy threshold according to defined evaluation criteria, such as a sufficiency metric, the signal is deemed absent. Applied to wireless communication networks, such supervision may be used to suspend or terminate transmission responsive to detecting the link signal's absence. In an exemplary embodiment for 1xEV-DV (cdma2000 Revision C) wireless networks, a mobile station selectively performs forward link supervision based on measuring the bit energy of power control bits received by the mobile on a dedicated power control sub-channel. If a fundicated channel is assigned to the mobile station, it may perform forward link supervision based on Frame Error Rate (FER) estimations for data received on the fundicated channel rather than the energy-based approach.
Abstract translation: 用于链路监视的方法和设备通过测量该信号的接收能量来确定链路信号是否存在或不存在。 如果信号的测量能量不符合定义的评估标准（例如充分度量标准）所定义的能量阈值，则认为该信号不存在。 应用于无线通信网络，这种监督可用于响应于检测到链路信号不存在而暂停或终止传输。 在针对1xEV-DV（cdma2000修订版C）无线网络的示例性实施例中，移动台基于测量移动站在专用功率控制子信道上接收的功率控制比特的比特能量来选择性地执行前向链路监督。 如果将基金化信道分配给移动台，则其可以基于基于信道信道接收的数据的帧误差率（FER）估计而不是基于能量的方法来执行前向链路监督。

Abstract: Techniques are provided for sequencing user data packets (e.g., voice packets) segmented into plural AAL2 packets which are in turn carried over Internet Protocol (IP). Concerning segmented user data packets, the techniques of the present invention utilize one or more predetermined values in the length indicator (LI) field in the headers of the certain ones of the plural AAL2 packets to carry information other than packet size information. Further, the techniques of the present invention use the User-to-User indicator (UUI) field of the AAL2 packets to carry AAL2 information such as segmentation nofitication and sequence-derivable information. For AAL2 packets which carry non-segmented user data packets (e.g., user data packets which can fit with the maximum size of a single AAL2 packet), the length indicator (LI) field contains the actual length of the AAL2 packet in conventional manner.
Abstract translation: 提供了用于对分割成多个AAL2分组的用户数据分组（例如，语音分组）进行排序的技术，所述多个AAL2分组依次通过互联网协议（IP）承载。 关于分段的用户数据分组，本发明的技术利用多个AAL2分组中的特定分组的头部中的长度指示符（LI）字段中的一个或多个预定值来承载除分组大小信息以外的信息。 此外，本发明的技术使用AAL2分组的用户 - 用户指示符（UUI）字段来携带AAL2信息，例如分段nofitication和序列可导出信息。 对于携带非分段用户数据分组的AAL2分组（例如，可以适合单个AAL2分组的最大大小的用户数据分组），长度指示符（LI）字段以常规方式包含AAL2分组的实际长度。
