A method in a network node () comprises establishing () a first bearer () between a local breakout function gateway (), the local breakout function gateway collocated at the network node, and an application client () of a wireless device (). The method comprises transmitting () network assistance information to the wireless device over the first bearer via application-layer signaling in the user plane, the network assistance information comprising information related to optimizing transmission of user data over a second bearer () established between the wireless device and a core network node ().

Methods and devices for providing a media description of a media stream to a client are described. The client is subscribed to a media description delivery service. The media description delivery service comprises a media description delivery rule. A request for a media description delivery is sent to a media server. From the media server a media description is received. It is verified that the received media description complies with the media description delivery rule and if the verification is in the affirmative, a delivery of the media description is initiated to the client.

Methods and devices for media description delivery

Systems and methods relating to delivery of an alternate representation of a requested segment of a media content item to a terminal device are disclosed. In one embodiment, a system comprises a terminal device and a network node. The terminal device is configured to send a request for a first representation of requested media content, and receive a response to the request comprising a second representation of the requested media content, where the second representation of the requested media content is different than the first representation of the requested media content. The network node is configured to receive the request from the terminal device for the first representation of the requested media content, select the second representation of the requested media content, and send the response to the terminal device comprising the second representation of the requested media content.

A method and a first node for managing processing of an audio stream as well as a method and a second node for enabling management, by a first node, of processing of an audio stream and corresponding computer programs and computer program products are disclosed. The audio stream is receivable from the second node. The first node sends, to the second node, information relating to at least one preference concerning acoustic characteristics of the audio stream. The second node processes the audio stream in response to the information relating to the at least one preference concerning the acoustic characteristics. The second node transmits the audio stream to the first node.

A method performed by a server of a communication network for making an HTTP media stream accessible to a client is provided. A Media Presentation Description (MPD) is generalized, such that the MPD is provided with at least one period element sequentially arranged according to a media play timeline. Each period element is provided with at least one representation such that at least one of the period elements is provided with at least two alternative representations. Each representation is provided with an ordered sequence of at least one media segment URI. Each media segment URI references at least one media segment of the HTTP media stream. The generated MPD enables a client to select representations and to acquire referenced media segments based on the selected representations.

Methods and arrangements for HTTP media stream distribution

A method for managing streaming media traffic at a network entity capable of assuming a first and a second radio channel state, a transition from the first to second radio channel state requiring a first predetermined time period t, comprising combining, at the network entity, at least two media segments such that a resulting combined media segment comprises media data equivalent to a second predetermined time period t, the second time period being greater than the first time period, transmitting, from the network entity, the combined media segment in the first radio channel state during a third time period t, initiating transition, at the network entity, from the first to the second radio channel state, and waiting, at the network entity after the initiating step, at least for a time period t=t&#x2212;t&#x2212;t, wherein the second time period is greater than the sum of the first and third time periods.

Technique for managing streaming media traffic at a network entity

A streaming server sends a multimedia stream for delivery by a hybrid unicast-broadcast delivery network to a mobile terminal. To assist that mobile terminal change access delivery from unicast to broadcast, the streaming server sends multimedia content timing information that indicates one or more interstices in the content of the multimedia stream. The mobile terminal receives such multimedia content timing information upon receiving the multimedia stream by unicast. Although the mobile terminal determines the same multimedia stream is also available by broadcast, the mobile terminal initiates a change from unicast to broadcast during an interstice. Because the mobile terminal delays the access change until an interstice, any data loss resulting from the access change has a minimal effect on a subscriber's experience of the multimedia content. Moreover, regular occurrence of interstices ensures that such change will not be significantly delayed, and thus, neither will use of broadcast.

Service layer assisted change of multimedia stream access delivery

An electronic device has a multimedia framework including an integration layer and a higher-level application layer. The integration layer includes predefined media processing components having an input/output interface configurable based on the type and format of media content delivered to the device during a streaming media session and that provide predefined media processing functions to the application layer for enabling playback of the media content. A streaming media management component included in the integration layer establishes and manages the streaming media session and configures one or more content pipes used during the streaming media session to access packets received by one or more sockets. The component also maps the content pipes to the sockets and processes packets retrieved from the one or more content pipes such that the media content is provided to corresponding ones of the predefined media processing components in accordance with their configured input/output interfaces.

Real-time network transport protocol interface method and apparatus

In a turbo coder, rate conversion and/or rate matching is achieved by deleting parity bits P and P from the outputs of two constituent coders, one supplied with data bits to be coded and the other supplied with the same data bits after interleaving. Deleted bits are determined by a rate matching control unit directly for the P bits and via a similar position interleaving step for the P bits. A similar rate matching arrangement is provided for only two of the three outputs of a rate convolutional coder, the third output corresponding to a strongest coding polynomial in terms of minimum free distance and none of its coded data bits being deleted.
