The present disclosure includes gateways and methods for node selection of virtual network nodes in virtual evolved packet core networks. The methods include receiving, at a gateway from an evolved Node B (eNodeB), an attach request for a user equipment (UE), and determining a network selection hint corresponding to the received attach request, where the network selection hint is used for determining a virtual network node for selection in a mobile cloud network. The methods further include determining a domain name for establishing a network connection based at least in part on the network selection hint, where the selected domain name is associated with a virtual network node in the mobile cloud network. The methods also include selecting a virtual network node associated with the determined domain name, and establishing a network session to the selected virtual network node.

Systems and method are provided that allow a mobile device to communicate over multiple access technologies at the same time, including a cellular access technology, such as LTE, and via an untrusted WLAN access. The untrusted access is initiated via internet key exchange. The mobile device uses the same IP address over both access technologies.

Leveraging multiple access technologies simultaneously

Consistent with embodiments of the present invention, a system may be provided to provide per-subscriber stream management comprising: a client capable of receiving a playlist containing a subset of segments associated with a video asset; a video application server to request subscriber state information and to build state representations in a subscriber database on a per-subscriber basis; a media segmenter capable of providing the video asset in multiple bit rates; a subscriber state manager capable of managing the current state of one or more subscribers in a subscriber database; and a stream manager capable of requesting the assignment of bandwidth from a wireless infrastructure on a per-subscriber basis.

Unique subscriber states for adaptive stream management

In a system and method for establishing communications in a communications network, a network service provider can assign IP addresses to mobile devices dynamically to conserve IP address resources. A network service provider can also implement network address translation to further conserve IP address resources and to provide improved security. If a requestor seeks to obtain an IP address of a mobile device and the address is a local address, the system determines if the mobile device has a network address translation (NAT) binding that associates the IP address of the mobile device with a public IP address. If the mobile device does not have a NAT binding, the system creates a NAT binding that associates the IP address of the mobile device with a public IP address.

Systems and methods are provided for providing redundancy and failover for servers communicating via an authentication protocol. Mirroring is initiated at the beginning of a Diameter application session by an enhanced Diameter server, which continuously provides updates of the Diameter session to one or more peer Diameter mirror servers and thereby maintains an active mirror of the session.

Session redundancy among a server cluster

A method of supporting access to a selected Internet Protocol (IP) multimedia application via an IP Multimedia Subsystem (IMS) is provided for a roaming mobile node (MN)&#x2014;i.e., user equipment (UE)served by a wireless telecommunications system. The method includes: includes establishing a first IP tunnel between the UE and a local access gateway of a visited network, the first tunnel being anchored at the local access gateway; establishing a second IP tunnel between the UE and a home gateway of a home network, the second tunnel being anchored at the home gateway; receiving data packets at the local access gateway for the UE; filtering the packets received at the local access gateway to suitably classify corresponding traffic into one of a plurality of data flows supported within the first tunnel at varying Quality of Service (QoS) levels; and filtering the received packets.

Packet filtering/classification and/or policy control support from both visited and home networks

A method and apparatus for transmitting signaling messages over the communication channel to a CDMA mobile station. If a one-half, one-quarter, or one-eighth frame voice packet is to be transmitted, augmenting that packet with signaling information to form, essentially, a full rate frame; if no more than N consecutive full rate frames are detected, deferring transmission of the signaling message, and thereafter, if another full frame voice frame is detected, substituting a frame of signaling information for the full frame voice frame. Advantageously, using this arrangement, most short signaling messages can be transmitted to a CDMA mobile station with minimal voice impairment.

A method of managing a multimedia call session conducted over a communications network () is includes: receiving a request to set-up the multimedia session over the communications network (), including a plurality of media types; and, establishing a separate single media session for each media type included in the request, the established sessions being between a plurality of participating terminals ().

Multimedia half-duplex sessions with individual floor controls

In a multimedia communications system (), a multimedia-based answering system () lowers the amount of air interface bandwidth used to send multimedia mail messages. When a called party is unavailable, a user of a user terminal () is given an option to send a multimedia mail message for the unavailable called party (). If the user wants to send a multimedia mail message, the bandwidth requirements for the call are renegotiated to reduce bandwidth for sending the multimedia mail message (). The multimedia mail message is then transmitted over-the-air to a multimedia mail system (), where the multimedia mail message is buffered, transcoded (if necessary) and stored until the called party retrieves it ().

Internet protocol enabled multimedia mail system with reduced bandwidth requirements

A communication device is described that includes a POTS interface system, a processing system, a conversion system, a voice interface system, and a digital interface system. When in operation, the POTS interface system receives analog voice signals for a call. The POTS interface system converts the analog voice signals from analog to digital to generate digital voice signals. The processing system performs an application on the digital voice signals to provide a presentation format of the digital voice signals of the call to a user. The conversion system then converts the digital voice signals into analog voice signals and a voice interface system transmits audible signals to the user. The digital interface system receives digital data signals from a data service provider and the processing system performs an application on the digital data signals to provide additional data to the user.

Communication device that provides enhanced services

In a multimedia communications system (), a conference establishment server coordinates the scheduling of a conference call. The server receives request for conference calls (). The request includes a list of participants and may include an indication of the resources necessary and any rules for the conference call. The request may indicate critical resources or participants that are required for the call. Based on the request, the server determines a conference time and notifies participants of the time (). Prior to conference time, participants are reminded of the time and automatically connected to the call. The server may check the status of users on the telecommunications network to determine availability. If a critical participant or resource is unavailable at conference time, the conference may be cancelled with notification to the participants.
