摘要： In a technique for setting up calls in IP mobile networks, when an application level in a mobile station sends a setup message to set up a multimedia call, before sending such a message over the radio interface, the mobile station performs the appropriate procedures to setup the appropriate bearers over the radio interface and in the network to satisfy the call requirements specified by the application level in the setup message. The technique applies to both mobile originated calls and mobile terminated calls, the called mobile station performing the transport level procedures after having received a setup message and before sending a confirmation/call acceptance message back to the calling party. Furthermore, the allocation of radio resources for PDP contexts that will be used to carry the media of a multimedia IP called is delayed so that no radio resources are allocated to the PDP contexts activated before the call control signaling is exchanged. The radio resources are allocated only when the call signaling has been completed and the called party has accepted the call and indicated the call characteristics that it can support. An indication is forwarded from the SGSN to the GGSN advising that no packets are to be sent on the PDP context because there are no radio resources for the PDP context.
摘要翻译：在用于在IP移动网络中建立呼叫的技术中，当移动站中的应用级别发送建立消息以建立多媒体呼叫时，在通过无线接口发送这样的消息之前，移动台执行适当的过程来设置通过无线电接口和网络中的适当载体来满足在设置消息中由应用级别指定的呼叫要求。该技术适用于移动发起呼叫和移动终端呼叫，被叫移动台在接收到建立消息之后并且在向呼叫方发送确认/呼叫接受消息之前执行传输级别过程。此外，将用于携带被叫做多媒体IP的媒体的PDP上下文的无线电资源的分配被延迟，使得在交换呼叫控制信令之前没有将无线电资源分配给激活的PDP上下文。无线电资源仅在呼叫信令完成并且被叫方已经接受呼叫并且指示可以支持的呼叫特性时被分配。指示从SGSN转发到GGSN，建议在PDP上下文上不发送分组，因为没有用于PDP上下文的无线电资源。

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 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： 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.
