摘要:
Methods and apparatus are presented for extending the protocol synchronization period between a PPP client and a PPP server, wherein the PPP server is located on a wireless communication device. In one aspect, the PPP server generates and sends an IPCP Configure-Nak message to the PPP client whenever the PPP client sends an IPCP Configure-Request message, wherein an arbitrary non-zero value is deliberately sent as the primary DNS address, the secondary DNS address, the primary WINS address, or the secondary WINS address is sent in the IPCP Configure-Nak message. The IP address is deliberately omitted from the IPCP Configure-Nak message.
摘要:
A generic quality of service (QoS) model that is not dependent on network technology is used to support QoS for communication networks utilizing different network technologies. The generic QoS model may include a superset of all QoS parameters for all network technologies being supported, e.g., 3GPP and 3GPP2. An application at a device may specify QoS for a traffic flow based on the generic QoS parameters in the superset. The generic QoS parameters may be converted to QoS parameters that are specific to a serving network. The converted QoS parameters are exchanged with the serving network and are used while exchanging traffic with the serving network.

For delayed transmission after reconfiguration of the physical layer, a wireless network initially sends a first message (e.g., a Reconfiguration message) to a wireless device for reconfiguration of uplink and/or downlink physical channels. The wireless network then performs synchronization to establish the uplink physical channels, and the wireless device performs synchronization to establish the downlink physical channels. Upon completing the downlink synchronization, the wireless device sends a second message (e.g., a Reconfiguration Complete message) to the wireless network. The wireless network sends a Layer 2 acknowledgment (L2 ACK) upon successfully decoding the second message. The wireless network delays transmission of signaling/data on the downlink, except for transmission of certain messages such as those needed for reconfiguration, until successful decoding of the second message. The wireless device delays transmission of signaling/data on the uplink, again except for certain messages, until reception of the L2 ACK.
摘要:
A method, system, and computer program for adaptively streaming multimedia content is disclosed. An adaptive stream manager monitors at least one parameter of a user terminal. The adaptive stream manager monitors at least one parameter of the user terminal and predicting a future value of at least one parameter of the user terminal. The adaptive stream manager also selects a target characteristic, based on the predicted future value of the at least one parameter of the user terminal, and requests a multimedia segment having the target characteristic from a media server.
