摘要:
Systems, methodologies, and devices are described that facilitate transferring a subset of compression context from a source base station to a target base station during an inter-base station handover of a mobile device to facilitate establishment of compression context between the mobile device and target base station. The source base station can transfer a subset of compression context comprising static and semi-static context to the target base station during inter-base station handover to at least partially establish compression context between the mobile device and target base station prior to or during handover. The source base station can transmit, to the mobile device, indicator information related to compression context transferred. The target base station can at least partially establish compression context based on received subset of compression context to facilitate efficient communication with the mobile device and can establish any remaining portion of compression context with the mobile device after handover.

摘要:
Methods and systems to enhance local repair in robust header compression (ROHC) decompressors (110, 114), which may improve network transmission efficiency and quality. One method uses lower layer information to enhance local repair at the decompressor (110, 114). Another method uses a User Datagram Protocol (UDP) checksum to enhance local repair at the decompressor (110, 114).

摘要:
Methods and apparatus providing intelligent interface selection for legacy and non-legacy applications. The method includes intercepting a networking function call from an application desiring radio access, selecting a radio from a plurality of candidate radios based on selection criteria, and binding the radio to the application. To facilitate flow mobility, the method includes allocating an ephemeral port to the radio, generating a flow binding rule based only on the ephemeral port, and signaling the flow binding rule to a home agent.
摘要:
An apparatus and method for receiving a request for authorization and access from a requestor; determining the association of a care-of-address (CoA) in the request with an access technology used by the requestor; administering authorization rules based on the association of the care-of-address (COA) and the access technology; and determining either to allow access or to deny access to the requestor using results from administering the authorization rules.
摘要:
A mobile station that is configured to facilitate coordination of supplementary services in a centralized fashion may include circuit-switched (CS) domain components that are configured to place voice telephone calls in a CS domain. The mobile station may also include IP multimedia subsystem (IMS) components that are configured to place voice telephone calls in an IMS domain. The IMS components may include a transport component for facilitating communication with an IMS core network. The IMS components may also include a signaling component that is configured to exchange information with a centralized server on the IMS core network via the transport component. At least some of the information that is exchanged with the centralized server may be related to supplementary services for the voice telephone calls in the CS domain as well as the voice telephone calls in the IMS domain.
摘要:
Methods and apparatuses are provided that facilitate detaching one of a plurality of network connections to ensure state information is retained at one or more network nodes. For a device initiated detach, the device can transmit a handover message related to performing a handover of one network connection to another active network connection, as opposed to explicitly detaching the network connection. This can cause at least some state information, such as a gateway identifier, to be retained in one or more network nodes. For a network initiated detach, a gateway can provision state information to a state information server following receiving a routing tunnel termination message to ensure state information deleted as a part of the detach is re-provisioned to the state information server.
摘要:
An apparatus and method for associating a gateway control session with an Internet protocol connectivity access network (IP-CAN) session comprising receiving an IP address for a home agent/local mobility agent (HA/LMA); receiving an access terminal (AT) network access identifier (NAI); and associating the gateway control session with the IP-CAN session using the IP address and NAI. In one aspect, a policy charging and rules function (PCRF) receives an access point name (APN) information as: a Vendor Specific Option of either an IP control protocol (IPCP) or an IPv6 control protocol, a configuration option in a Vendor Specific Network Control Protocol, or a dynamic host configuration protocol extension for associating the sessions. The PCRF receives an AT IP address allocation and subsequently establishes the gateway control session to associate two sessions. The PCRF receives a correlation identifier in the gateway control session and in the IP-CAN session to associate two sessions.
摘要:
This disclosure enables a radio access network to control media data rates and codec parameters selected during multimedia session establishment. As the load on a radio network changes, operators desire to have the ability to control what data rate new multimedia sessions (e.g., VoIP) are to utilize, thereby allowing the operator to conduct a trade-off between voice/video quality and capacity during heavy loading periods. The multimedia communication session may be initiated with a determined guaranteed bit rate, where the guaranteed bit rate is requested, negotiated as one of several acceptable guaranteed bit rates, or based upon maximum system capacity, to take advantage of maximum data rate for the equipment in use. The session may also be initiated with a determined Quality of Service based upon either a network or user equipment installed policy.
