摘要： A mobile station (100) and a compression/decompression node in a wireless network (5), preferably the GGSN 30 (30), agree on whether to apply compression/decompression, and what compression/decompression scheme to use either by pre-configuration (when the GGSN 30 is in the home network of the mobile terminal) or by signalling (when the GGSN 30 is in a visited or a roamed-to network). Additional information, such as a profile-specific dictionary, may be used to increase the compression efficiency, particularly during start-up. Dynamic data can also be accommodated. The compression/decompression may be turned on and off on a packet-by-packet basis, depending on whether the compression actually results in a smaller packet. A compressed/uncompressed indicator bit or bits can be inserted explicitly on a per packet basis, and/or the compressed/uncompressed indication can be derived implicitly. A desired data compression/decompression algorithm, or any desired Proprietary Feature, can be signaled, possible without requiring standardization changes, by using a Packet Data Protocol PDP Context Activation message with a predetermined Access Point Name (APN) message information element that is sent from a first network element to a second network element for at least identifying the desired compression/decompression algorithm. It another embodiment, for the case where Proprietary Feature capability is exchanged between a RAN and a UE network element, a transmission of an extension to a UE Capability Enquiry message is sent to the UE for identifying the Proprietary Feature.
摘要翻译：无线网络（5）中优选地GGSN 30（30）中的移动台（100）和压缩/解压缩节点就是否应用压缩/解压缩以及通过预配置来使用什么压缩/解压缩方案是一致的（当GGSN 30在移动终端的家庭网络中时）或通过信令（当GGSN 30在访问或漫游到网络中时）。可以使用附加信息，例如特定于配置文件的字典来提高压缩效率，特别是在启动期间。也可以适应动态数据。取决于压缩是否实际导致较小的分组，压缩/解压缩可以逐个分组地打开和关闭。压缩/未压缩的指示符位可以以每个数据包为基础被明确地插入，和/或可以隐式地导出压缩/未压缩的指示。通过使用具有预定接入点名称（APN）消息信息元素的分组数据协议PDP上下文激活消息，可以用信号通知所需的数据压缩/解压缩算法或任何期望的专有特征，而不需要标准化改变用于至少识别所需的压缩/解压缩算法的第二网络元件的第一网络元件。在另一实施例中，对于在RAN和UE网元之间交换专有特征功能的情况，将向UE功能查询消息的扩展的传输发送给UE以识别专有特征。

摘要： A system and method for including aggregation control information in an aggregate frame that facilitates enhanced power efficiency is provided. Aggregation control information may include lengths of frames addressed to different stations and/or transmission opportunities to different stations. A receiving station is then able to calculate an offset within the aggregate frame that identifies the position of frames addressed to the receiving station and/or offset when it can use the medium to transmit it's data. The receiving station may then enter a sleep mode and awaken at a proper time for using the medium to either receive, or transmit data on the medium. Additionally, aggregation control information may include rate information to facilitate aggregation of multi-rate data in an aggregate frame.

摘要： Methods and systems for carrying call control information after a call handover from an Internet Protocol (IP) packet switched network to a circuit switched cellular network and vice versa. The IP packet switched network includes a processing server capable of processing IP-based protocol messages. The circuit switched cellular network includes a mobile switching center. A gateway is operatively connected as a bridge between the IP packet switched network and the circuit switched cellular network. The gateway is capable of encapsulating an IP-based protocol message into a payload of a second message, and extracting an IP-based protocol message from a payload of another message. One or more user devices are capable of transmitting and receiving to/from the IP packet switched network and the circuit switched cellular network. The user devices are capable of encapsulating an IP-based protocol message into a payload of a second message, and extracting an IP-based protocol message from a payload of another message. The IP-based protocol message contains call control information that is encapsulated, transparently transferred through the switched cellular network, and extracted. The call control information is transferred between the IP packet switched network and the user device. The circuit switched cellular network may be part of a circuit switched cellular system that also includes an overlayed packet switched network. The call control information may be carried in packets between the IP packet switched network and the user device transparently through the overlayed packet switched network.

摘要： A method of relocating the header compression context in a packet network which transmits packets having compressed headers. A connection is established between a mobile terminal and a first network entity and context information used with compression and decompression of the headers of the packets is stored at the mobile terminal and the first network entity. The context information updating is stopped in the mobile terminal and in the first network entity and after that, a snapshot of the compression and decompression context information is taken and stored in the first network entity. The connection between the first network entity and the mobile terminal is changed to a connection between the mobile terminal and a second network entity. The context information snapshot stored by the first network entity is transferred to the second network entity to be stored therein as the context information of the second network entity. The stored context information at the mobile terminal and the second network entity is then used for compression and decompression of the headers of the packets.

摘要： A method of deliveries data and to a mobile node for receiving data delivered from a packet-switched data network. A first registration of the mobile node is performed to a first network of a first access technology, and an additional second registration of the mobile node is performed to a second network of a second access technology by using an address associated with the mobile node in said first network. An interface of the mobile node towards the second network is deactivated and the mobile node is set into an idle mode of the first network. When an incoming signaling of the first network is received at the mobile node, it is used as a trigger for activating the interface to the second network. Thereby, efficient data delivery via the second access technology, for example, WLAN technology, is allowed to bring down the communications charges and yet cellular efficient power consumption is achieved in idle mode, by camping on the first access technology, for example, cellular technology.

摘要： A method for saving power, at a mobile terminal, includes receiving a call, at a network entity, wherein the call contains information relating to transmission of the call from the network entity to the mobile terminal. The mobile terminal operates in first and second communications networks, which are different. The mobile terminal detects coverage of the first communications network and activates a first interface corresponding to the first communications network. The mobile terminal can also deactivate the first interface and activate a second interface corresponding to the second communications network while the mobile terminal is located in both the first and second communications networks. The mobile terminal can then enter a low power consumption mode supported by the second communications network. The mobile terminal can also deactivate the low power consumption mode and activate the first interface to communicate with the first communications network when a call is delivered via the first communications network.
