摘要:
A service request (150) having a predefined QoS (152) can be received from an end-user device (105) by a transit device (110). The transit device (110) can act as an access point for the end-user device (105) to connect to a mobile broadband network (135). A transport resource (130) of the transit device (110) can be allocated to handle a data flow of the received service request (150). The network address of the allocated transport resource (130) can be recognized by the mobile broadband network (135). The network addresses associated with data packets (160) of each data flow supporting the service request (150) can be translated by the transit device (110). The translation can occur between the network address of the end-user device (105) and the network address of the transport resource (130) allocated to the data flow based upon a directionality of the data packets (160).
摘要:
A method for minimizing tunnels in a network, apparatus and computer-readable storage medium having computer readable code stored thereon for programming a computer to perform the method. The method includes the steps of: obtaining state information associated with a first node connected to a mobile network behind a mobile node; receiving a first message sent between the first node and a correspondent node, wherein a first header was removed from the first message prior to sending the first message; recreating, in one of the mobile node and a mobility agent, the first header using the state information; and sending the first message with the first header.

An apparatus and method for multicast data stream selection in a communication system includes a first step 300 of providing an intermediate server between a service entity and mobile clients. A next step 302 includes receiving a join request from a mobile client. A next step 304 includes deriving subgroups with each subgroup having at least one associated multicast data stream. A next step 310 includes deriving subgroup outer tunnels. A next step 316 includes encoding different data streams for the associated subgroups. A next step 320 includes mapping each data stream to the respective outer tunnels for each subgroup. A next step 322 includes sourcing the mapped streams to each subgroup. A next step 324 includes converting the mapped streams to a form that can be recognized by the mobile clients.

A method and system for establishing floor control in a communication session enables remote control of devices in a network and provides a status update concerning floor ownership. The method includes processing at a floor controller a floor request message received from a first endpoint, where the floor request message requests that floor ownership be provided to a second endpoint (step 305). A floor control announcement message is then transmitted from the floor controller to at least both the first endpoint and the second endpoint, where the floor control announcement message indicates that the second endpoint has floor ownership (step 315).
摘要:
A method, apparatus, and system for performing facial recognition utilizing large databases is provided herein. During operation a large database is quickly narrowed by determining an automobile attribute (e.g., a license plate number) and determining a registered owner and possibly an address based on the automobile attribute. The image database is narrowed based on the registered owner of the vehicle, and possibly the address of the registered owner.
摘要:
A client entity generates a subscription to a presentity that includes a sequence of events which define a trigger that controls when a presence server sends a notification to the client entity; and the subscription further indicates a time period parameter for the sequence of events. Upon receiving the subscription, the presence server receives and monitors presence information based on the indicated time period parameter to detect an occurrence of the sequence of events, and sends the notification to the client entity when the presence information satisfies the trigger.
摘要:
An intermediary function receives a reservation request for a desired throughput from the sourcing device, and determines a set of bearers whose aggregate throughput approximates the desired throughput. The intermediary function requests from at least one access network the set of bearers whose aggregate throughput approximates the desired throughput, and receives from the at least one access network an allocated set of bearers, wherein the allocated set of bearers comprises one or more bearers. The intermediary function informs the sourcing device of an aggregate throughput of the allocated set of bearers, receives user plane data from the sourcing device, and associates the user plane data with the allocated set of bearers in order to transport the user plane data to the receiving device. Subsequent modifications to the allocated set of bearers causes the intermediary function to inform the sourcing device of the modified aggregate throughput of the allocated set of bearers.
摘要:
Some embodiments are directed to methods and apparatuses for enabling voice discussions about a same data content being independently and simultaneously accessed on at least two devices. A server detects when a first device of the at least two devices accesses the data content. The server identifies and reserves an available voice communication group resource. Responsive to detecting that the at least two devices are independently and simultaneously accessing the data content, the server identifies and reserves an available voice communication group resource, and sends a voice group identifier for a reserved voice communication group resource to the at least two devices to allow access to the reserved voice communication group resource.
摘要:
A method and apparatus for transmitting a subset voice stream associated with a subset talk group. A voice communication device receives a session identifier from an associated data communication device engaged. The voice communication device transforms the session identifier into a session key identifier, obtains an encryption algorithm implementing a subset talk group filtering feature and a voice encryption key identifier, and combines the session key identifier with the voice encryption key identifier to generate a signaling key identifier. The voice communication device associates the signaling key identifier and an encryption algorithm identifier with the subset voice stream during transmission of the subset voice stream to a receiving voice communication device.
摘要:
A method and apparatus distributes video packets over multiple bearers for providing unequal packet loss protection. The method includes a packet processing function receiving a plurality of packets collectively comprising a flow of sequential data included in a sequence of media frames. For each packet, the packet processing function: applies a bearer selection process to select one of a plurality of bearers for transporting the packet over an access network, wherein each bearer has a different quality of service level which influences the probability of the transported packets being intentionally discarded by the access network, wherein the bearer selection process causes distribution of the plurality of packets across the plurality of bearers such that each bearer carries non-consecutive packets both within any given media frame and across sequential media frames and provides unequal packet loss protection for the packets in the plurality; and provides an indication of the selected bearer.
