A method and apparatus for transmitting a real-time media stream in a communications network. The method comprises separating an essential part of the media stream from a non-essential part of the media stream in said real-time media stream and transmitting the essential part of the media stream on a first bearer and the non-essential part of the media stream on a second bearer. Priority of the first bearer is higher than priority of the second bearer. The method also comprises performing adaptation of the essential part of the media stream in response to a change of traffic conditions on the second bearer.

Method and apparatus for transmitting real-time media stream

Embodiments include methods performed by an evolved Node B (eNB) configured with a Long-Term Evolution (LTE) radio access technology (RAT). Such methods include managing access to resources of the LTE RAT by a user equipment (UE) served by the eNB, based on one or more radio resource management (RRM) policies for the LTE RAT. Such methods also include sending, to a next-generation Node B (gNB) configured with a New Radio (NR) RAT, a request to establish dual connectivity with the UE as a secondary node (SN), wherein the request includes a Subscribers Profile ID for RAT/Frequency Priority (SPID) that is associated with the one or more RRM policies. Other embodiments include complementary methods performed by a gNB, as well as eNBs and gNBs configured to perform such methods.

A system, computer software and method for collecting, in addition to position data, additional positioning data in a user terminal served by a communication network. The method includes initiating, by generating a message within the user terminal, collection of the positioning data, where the positioning data includes information based on which a physical location of the user terminal is determined; measuring, by the user terminal, at least one parameter related to the physical location of the user terminal in response to the message; producing, within the user terminal, measurement reports that include the at least one parameter; selecting, within the user terminal, one or more measurement reports that were generated in response to the message generated by the user terminal; reporting the selected one or more measurement reports to an interface within the user terminal; and transmitting, from the interface, the reported one or more measurement reports to an external server or to the communication network.

Measurement systems and methods for fingerprinting positioning

Exemplary embodiments include methods and/or procedures performed by a first network node () in a radio access network, RAN, the first network node () being in communication with a second network node () configured with a different radio access technology, RAT, than the first network node (). Such exemplary embodiments include determining () one or more radio resource management (RRM) identifiers associated with at least one of the following: a user equipment, UE, served by the first network node; a subscriber associated with the UE; and a group of UEs served by the first network node. Exemplary embodiments also include esending () a request for the second network node to establish dual connectivity, as a secondary node, SN, with the UE, wherein the request comprises information relating to the one or more RRM identifiers. Some embodiments can include managing () the UE's access to resources provided by the RAN based on one or more policies associated with the one or more RRM identifiers, while the information relating to the one or more RRM identifiers can map to one or more further policies for managing UE access to resources provided by a RAN including the second network node.

A service class for a transmission of data packets between a service entity and a user equipment is selected from a plurality of service classes. A first transmission context is established between a core network node and the user equipment, and is associated with a first set of attributes for defining a first quality of service for the transmission. Furthermore, a second transmission context is established between an access node and the user equipment, and is associated with a second set of attributes for defining a second quality of service for the transmission. The selected service class determines the first set of attributes by a first unique mapping function performed in the core network node and the selected service class determines the second set of attributes by a second unique mapping function performed in the access node.

Method and devices for specifying the quality of service in a transmission of data packets

A method for configuring a QoS for a wireless communication network bearer corresponding to a wireless device is provided. The method includes assigning a first QoS profile to the bearer when the wireless device is in a first QoS region served by a first wireless communication network cell, the first QoS profile corresponding to a first QoS available in the first wireless communication network cell but not available to the wireless device in a second wireless communication network cell neighboring the first wireless communication network cell. The method further includes establishing communication for the bearer between the wireless device and the second wireless communication network cell when the wireless device begins a handover process with the second wireless communication network cell, the communication for the bearer being established using the first QoS profile but corresponding to a second QoS level different from the first QoS level.

QoS configuration for a wireless device

This disclosure relates to a method, and an arrangement and a computer program for updating a prioritization level of a service data flow between a user node and a network node. The method comprises obtaining a traffic size per time unit of detected data packets of the service data flow, and updating the prioritization level of the service data flow, based on the obtained traffic size per time unit. It is an advantage that embodiments provide a possibility to determine a trade-off between the need to optimize response times for short-lived data sessions and limiting the impact on other users when prioritizing long-lived high volume sessions. It is advantageous that the embodiments are applicable to situations in which a direct classification, using IP 5-tuple or deep packet inspection is not meaningful.

Method, apparatus and computer program for updating a prioritization level of a service data flow based on traffic size per time unit of said data flow

A radio communication handling device handling communication for an application running in a mobile station and communicating with an application server via a mobile communication network includes a radio resource determination unit that determines a state transition for the radio resources between the mobile station and the mobile communication network from a first current state to a second state, where the first state involves communication with a higher bandwidth than the second state, and informs, prior to the transition, at least one application communication control unit about the transition in order to allow the application communication control unit to release unused application communication connections before the transition. The application communication control unit receives the information about the following state transition and determines whether to release an application communication connection or not based on the information.

Radio efficient TCP release

A method of controlling streaming of data, such as video, from a streaming server to a User Equipment (UE) via a Radio Access Network (RAN) is provided. The method includes receiving streaming data from the streaming server, re-shaping the received streaming data into bursts, and transmitting the bursts to the UE. The bursts are transmitted at a higher bitrate than the bitrate of the received streaming data. By re-shaping the streaming data into bursts, streaming can be effected in a more radio-friendly way, since the UE may switch to a less resource consuming radio state in-between reception of data bursts delivered at high bitrates. Further, a corresponding computer program and computer program product, and a proxy unit for controlling streaming of data from a streaming server to a UE via a RAN, are provided.

Controlling streaming of data from a streaming server to a user equipment via a radio access network

A method for specifying the quality of service in a transmission of data packets between a service entity (AF) and a user equipment over a mobile network is described. The mobile network comprises a core network node (SGSN) and an access node (NB, RNC) which are adapted to control the handling of data packets sent between the service entity (AF) and the user equipment (UE). A plurality of service classes relating to the quality of service are preconfigured and a selected service class is selected from said plurality for the transmission. A first transmission context (PDP) is established between the core network node and the user equipment (UE), said first transmission context being associated with a first set of attributes for defining a first quality of service for the exchange of the data packets with the user equipment in the transmission. Furthermore, a second transmission context (RAB, RB) is established between the access node (NB, RNC) and the user equipment (UE), said second transmission context being associated with a second set of attributes for defining a second quality of service for the exchange of the data packets with the user equipment in the transmission. The selected service class determines the first set of attributes by a first unique mapping function performed in the core network node and the selected service class determines the second set of attributes by a second unique mapping function performed in the access node. A corresponding mobile network, control device and computer program are also described.

Data traffic between a user at a user equipment and a network resource is preceded by a lookup procedure for obtaining a network address of the network resource. A message of the lookup procedure is processed depending on a class of users to which the user belongs. If the user belongs to a first class of users, the message of the lookup procedure is processed for adapting the lookup procedure to return a first network address of a replacement network resource capable of handling the data traffic. If the user belongs to a second class of users, the message of the lookup procedure is processed for adapting the lookup procedure to return a second network address of a replacement network resource capable of handling the data traffic.
