Network devices, servers, and modules operating within MCA capable to selectively defer delivery of non-time sensitive content are provided. A network device () includes a communication interface () configured to enable communication with a client device (), and to receive a request for a content delivery from the client device (). The network device also includes a processing unit () configured to determine whether to defer the request depending on a network load at a time when the request has been received.

Devices and methods using network load data in mobile cloud accelerator context to optimize network usage by selectively deferring content delivery

The invention relates to a content delivery entity () configured to deliver a first data traffic from a first Internet content provider () to a mobile user equipment () via an access network of a mobile communications network. The entity () comprises an interface () configured to detect the first data traffic that shall be treated with priority. An acceleration unit () is configured to accelerate the delivery of the first data traffic from the first Internet content provider to the content delivery entity, and a controller () is configured to forward the first data traffic from the first Internet content provider () to the mobile user equipment () in the access network in such a way that the first data traffic from the first Internet content provider () is routed to the mobile user equipment () in the access network with a priority different from that of a second data traffic that is delivered from a second Internet content provider () through the access network.

Accelerated content delivery

A method and apparatus for delivering network operator advertisements to a mobile terminal in association with providing content from a content delivery network (CDN) are disclosed. A network node resides within a wireless communication network supporting the mobile terminal. The network node receives a content request directed to locally-cached content from the CDN, and determines that the requested content includes or is associated with an advertisement placeholder. In response to this determination, the network node sends an advertisement ID request that includes a network operator ID to an external advertisement server. An advertisement ID is received from the advertisement server responsive to the advertisement ID request. The network node maps the advertisement ID to a network operator advertisement associated with the advertisement ID, and dynamically links the network operator advertisement to the requested content. The network node delivers the requested content, including the network operator advertisement, to the mobile terminal.

Method and apparatus for display of operator ads

A technique for compressing header information to produce a compressed header portion of a data packet to be transmitted across a communication channel includes generating a checksum from the header information, and providing the checksum as the compressed header portion.

Robust header compression in packet communications

A node of a telecommunications network comprises a first function configured to perform a first operation on a first portion of a packet handled by the node and a second function configured to perform a second operation on a second portion of the packet. The first function and the second function are configured to employ a shared transaction for operating on the packet whereby, by virtue of the shared transaction, after performance of the first operation and the second operation, the packet has less overhead attributable to the first function and the second function than if the shared transaction had not been employed in performance of the first operation and the second operation.

Plural telecommunications functions having sharing transaction(s)

Header compression repair techniques are accomplished, in various aspects, modes, embodiments, and implementations, by a remote terminal (), by a header decompressor () for use at a remote terminal (), and by methods of operating the remote terminal and/or decompressor, and (optionally) in some aspects, modes, embodiments, and implementations by taking into consideration aspects of structure and operation of a header compressor () as well. The remote unit () comprises a transceiver () or the like which receives, over a link () such as an air interface (), packets including packets having headers which have been compressed and packets which are potentially out-of-order. The header decompressor (), upon detection of non-receipt of packets anticipated in a flow () of packets over the link, stores, with respect to each non-receipt, a snapshot of header decompression context information existing at the non-receipt. Then, when the header decompressor detects header decompression failure for a subsequently received packet, the header decompressor determines (e.g., by executing a repair process) whether header decompression of the subsequently received packet can be achieved using one of plural stored snapshots.

Method and apparatus for handling out-of-sequence packets in header decompression

A Multimedia system and a method in a Multimedia system where a first user with user equipment () uses a Push to talk service (PTT) to communicate with at least one second subscriber's user equipment () using said Push to talk service (PTT), wherein a PTT-server () providing the PTT-service interacts with said first and second subscriber's user equipment () and exchanges information concerning relevant parameter values for each user equipment (), and each user equipment () adapting its application settings during the operation of said PTT-service, whereby degradation of the perceived quality is prevented

Method and system for setting application settings for a push-to-talk service

Systems and methods are provided for Internet Protocol (IP) based communication systems without using a complete Internet Protocol stack on both sides of a communication link. Various exemplary embodiments include communication of audio information over a wireless transmission channel to a wireless terminal from a network that includes transmission of audio information using voice over Internet Protocol (VoIP). A first communication system and method may include a wireless terminal having a dedicated audio application that includes processing for header compression and decompression. A second communication system and method may include a wireless terminal and a network device (e.g., a network transmitter/receiver terminal), each containing at least a portion of an Internet Protocol stack, and the network device may include a header modification means that may reduce or eliminate the header from VoIP packets it will send to the wireless terminal.

Systems and methods for VoIP wireless terminals

An access technology integrated header compression method or apparatus sends an IP-based speech data packet over a radio interface without sending information related to changes in the IP identification, RTP sequence number, or RTP time stamp. The omission of information related to changes in these fields from the header reduces the bandwidth consumed by the header. These fields are then reconstructed at the receiver side of the radio interface.

Access technology integrated header compression

A system, method, and apparatus for increasing the efficiency of the compression of a communication protocol for use over bandwidth limited communication links. One aspect of the present invention uses the knowledge of the structure and content of communication protocols to form a static dictionary or static binary code tree. As a result, the compression efficiency can be greatly increased. Another aspect of the present invention provides a combined static and dynamic dictionary or binary code tree to perform communication protocol compression. In one aspect of the invention, the static binary code tree or static dictionary is constructed by studying flows of data protocols in the conditions of their intended usage.

Static information knowledge used with binary compression methods

In packet communications that utilize header compression/decompression, relatively fast and reliable header compression context updates can be accomplished with relatively low overhead by: sending anticipatory context update requests before decompressor context invalidation is detected; sending redundant context update requests; and sending redundant context updates. Transmission parameters associated with both context update requests and context updates can be controlled appropriately to improve their chances for delivery, and needless context update requests can be identified and ignored at the header compression side.

Efficient header compression context update in packet communications

A telecommunications network has first and second entities (and) which communicate by sending a packet () having a compressed header (). A header compression key () is associated with (e.g., included in) the packet. The header compression key has a first field (A) which, in a first mode of the invention, is utilized exclusively for distinguishing between different flows of compressed packets (CIDs). In a second mode of the invention, the first field (A) of the header compression key can be utilized either for distinguishing between the different flows of compressed packets or for distinguishing between different header compression identifiers. Whether the first field of the header compression key is employed exclusively for distinguishing between different flows of compressed packets (the first mode) or can also be employed for distinguishing between different header compression identifiers (second mode) depends on a value in a second field (B) of the header compression key. In the second mode, a first subset of values for the first field of the header compression key is employed to distinguish between different header compression identifiers, while a second subset of values for the first field is employed to distinguish between the different flows of compressed packets.

Context identification using header compression key at link layer

A method, system, and apparatus for increasing the efficiency and robustness of the compression of a communication protocol for communication between entities over bandwidth limited communication links. The present invention uses the request-reply nature of communication protocols to update compression and decompression dictionaries. Each communication entity will update its dictionary with a new message as soon as it is known that the other communication entity has access to the message. In one aspect of the present invention, an entity updates a compression/decompression dictionary by updating the dictionary with sent messages as soon as a reply arrives from the other entity, and by updating the dictionary with received messages immediately. In another aspect of the present invention, received messages are used to update an entity's decompression dictionary and sent messages are used to update an entity's compression dictionary.

Communication system and method utilizing request-reply communication patterns for data compression

A system, method, and apparatus for increasing the efficiency of the compression of a communication protocol for use over bandwidth limited communication links. One aspect of the present invention provides for the sharing of context information between a compressor and decompressor at each communication entity in a communication system. As a result, context information will be shared for each channel pair. In another aspect of the present invention, multiple communication sessions between communication entities may share the same context information for the compression and decompression of communication messages.
