20090022107 | COMPRESSION STATIC AND SEMI-STATIC CONTEXT TRANSFER - 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. | 01-22-2009 |
20090190471 | Method and Apparatus for Optimized Session Setup with Network-Initiated QoS Policy Control - Apparatus and methods operable by a network in configuring quality of service (QoS) for an access terminal are operable to receive, at a network, a request for packet data access from an access terminal. The apparatus and methods are further operable to determine, at the network and based on establishment of the packet data access, an initial QoS policy configuration for at least one reservation link corresponding to at least one application on the access terminal, wherein the initial QoS policy configuration is based on preconfigured information and comprises initial QoS parameters for the at least one application. Additionally, the apparatus and methods are operable to establish the at least one reservation link with the access terminal, prior to initiation of the at least one application on the access terminal, wherein the at least one reservation link includes the initial QoS parameters for the at least one application. | 07-30-2009 |
20090191841 | Method and Apparatus for Extended Call Establishment for IMS Emergency Calls - Apparatus and methods of establishing an emergency voice call include user equipment transmitting, and a first serving core network receiving, a request for an emergency call via a wireless access network. The apparatus and methods further include a determination by the first serving core network of an alternative serving core network. In some aspects, the determination may be made based on a user equipment location from a location retrieval function, which may obtain such information from other network components or from the user equipment. In other aspects, the determination may be based on lack of capability or lack of capacity. Further, the apparatus and methods also include establishment of the emergency call with a second serving core network different from the serving core network based on the determination. | 07-30-2009 |
20090252118 | HANDOFF BETWEEN PACKET-SWITCHED NETWORK AND CIRCUIT-SWITCHED NETWORK - Techniques for supporting handoff of terminals between a packet-switched network and a circuit-switched network are described. In an aspect, handoff between packet-switched and circuit-switched networks may be facilitated by a designated network entity in the packet-switched network. The designated network entity may interface with both the packet-switched network and the circuit-switched network, perform circuit-switched call origination, and perform handoff procedure. In one design, a first terminal may communicate with the packet-switched network for a packet-switched call with a second terminal. The first terminal may initiate handoff to the circuit-switched network via the designated network entity. The first terminal may perform handoff from the packet-switched network to the circuit-switched network based on an inter-MSC handoff procedure. The first terminal may then communicate with the circuit-switched network for the circuit-switched call with the second terminal after the handoff. | 10-08-2009 |
20090303932 | METHODS AND APPARATUS FOR FACILITATING NETWORK-BASED CONTROL OF A FORWARDING POLICY USED BY A MOBILE NODE - A mobile node receives access network-specific signaling that is related to an Internet Protocol (IP) flow. The mobile node decides which of multiple access networks to use to send the IP flow based on the access network-specific signaling. The access network-specific signaling may be received from an access network, and the mobile node may interpret the access network-specific signaling as a command to send the IP flow over that access network. The mobile node may update a forwarding policy at the mobile node to indicate that the IP flow should be sent over that access network. | 12-10-2009 |
20100009690 | MANAGING NETWORK-INITIATED QUALITY OF SERVICE SETUP IN MOBILE DEVICE AND NETWORK - Systems, methodologies, and devices are described that manage employment of network (NW)-initiated resource allocation and user equipment (UE)-initiated resource allocation for a UE. To employ NW-initiated resource allocation, a core network can transmit an indicator to the UE indicating that Policy and Charging Control (PCC) is supported by a network associated with the UE. The UE receives the indicator and other information, such as indicator regarding whether the current access network supports NW-initiated resource allocation and whether the current application prefers NW-initiated resource allocation, determines that NW-initiated resource allocation is to be employed, and the core network initiates resource allocation for the UE. If any indicator is not received by the UE, or the UE receives an indicator that indicates PCC is not supported or not preferred, the UE determines that UE-initiated resource allocation is to be employed, and transmits a request for resource allocation to the core network. | 01-14-2010 |
20100080172 | PROXY MOBILE INTERNET PROTOCOL (PMIP) IN A MULTI-INTERFACE COMMUNICATION ENVIRONMENT - A communication entity (such as a User Equipment (UE), an Access Gateway (AGW), a Packet Data Network Gateway (PGW), a Policy Charging Rule Function (PCRF), and so forth) notifies another communication entity that the UE intends to use a single Internet Protocol (IP) address for connections to multiple AGWs. The communication entity also sends information that is related to at least one of the UE's IP flows to another communication entity. | 04-01-2010 |
20100169910 | APPARATUS AND METHODS OF SELECTIVE COLLECTION AND SELECTIVE PRESENTATION OF CONTENT - Disclosed are apparatus and methods operable to distribute targeted content. Additionally, disclosed are corresponding apparatus and methods operable to selectively choose and cache selected ones from among the distributed targeted content, and to further choose ones from among the cached content to present on a device. In some aspects, selective caching of content may be based upon a match between predetermined content attribute information and predetermined profile information. Further, in some aspects, an indicator is operable to trigger the selective inclusion of one or more of the cached content in a presentation of other content, which may be based on a match between a desired content attribute associated with the indicator and the respective predetermined content attribute information of the cached content. | 07-01-2010 |
20100197305 | CORRELATING REGISTRATIONS ORIGINATING FROM A DEVICE - Systems and methods for correlating multiple registrations from a single device are disclosed. A private ID used in an prior registration may be used to obtain subsequent private IDs. The subsequent private IDs may be used in subsequent registrations. An instance ID from an prior registration may be used in conjunction with different registration IDs in subsequent registrations. | 08-05-2010 |
20110016313 | HEADER COMPRESSION FOR TUNNELED IPsec PACKET - Aspects describe compressing the concatenation of IP headers, UDP headers, ESP headers, and potentially other headers inside the ESP header. The multiple headers are regarded as one header chain and compressed as a single header chain. The compression can utilize a robust header compression (ROHC) framework. The ROHC ESP profile can be utilized as a basis for compression of ESP/UDP/IP headers with the addition of static chains and dynamic chains for multiple layer transport and application layer headers. Static chains include UDP static header fields either between static IP header fields and static IP header fields or between static IP header fields and static ESP header fields. Dynamic chains include UDP dynamic header fields either between dynamic IP header fields and dynamic ESP header fields or between static IP header fields and static IP header fields. | 01-20-2011 |
