Methods and apparatuses for updating policy and charging rules relating to early dialogs in session initiation protocol forking in a telecommunications network. A node comprises a receiver (), configured to receive a plurality of preliminary responses originating from a plurality of terminating end points as part of Session Initiation Protocol, SIP, forking. The node comprises an early dialog controller (), configured, for each received preliminary response, to determine a unique identifier and to control a transmitting means, which may be a transmitter (), to transmit a corresponding preliminary message comprising the unique identifier to a further node () for use as a Policy and Charging Rules Function, PCRF (), for creating an early dialog by the further node. The receiver is further configured to receive updated data for at least one of the preliminary responses. The node further comprises an updated dialog controller () configured to retrieve the unique identifier corresponding to the at least one preliminary response and control the transmitter to transmit an updating message based on the updated data and comprising the retrieved unique identifier to the further node for updating the corresponding early dialog.

Policy control in session initiation protocol forking

A method in a first network node handles data sessions in a communications network. The method includes receiving information indicating a second data session entering the communications network. The method further includes creating a second rule associated with the second data session. The second rule causes the first data session to be associated with the second data session. The method further includes determining that the second rule share a guaranteed bit rate (GBR) with a first rule associated with the first data session based on the second data session entering the communications network. The method further includes transmitting first information that the second rule and an indicator indicating the first rule and the second rule should share the GBR.

Sharing resource reservation

There is provided mechanisms for configuration of liveness check using Internet key exchange messages. A method is performed by a user equipment. The method comprises transmitting, to a core network node, a first Internet key exchange message comprising a configuration attribute indicating support of receiving a timeout period for liveness check. The method comprises receiving, from the core network node, a second Internet key exchange message comprising a configuration attribute indicating a timeout period for said liveness check.

Configuration of liveness check using internet key exchange messages

A technique for signalling activation or deactivation of a data-over-non-access-stratum, NAS, transmission scheme is disclosed, the transmission scheme being for transmitting data packets over the NAS between a terminal and a base station, and being started in an idle mode. In a method aspect, there are steps of determining a trigger condition indicating a need for the data-over-NAS transmission scheme, and signalling an indication for activation or deactivation in response to fulfilment or non-fulfilment of the determined trigger condition. In another method aspect, there may be steps of receiving the indication for activation or deactivation, and activating or deactivating the data-over-NAS transmission scheme in response to the signalled indication.

Technique for data-over-NAS signalling

A Machine-to-Machine (M2M) services enablement architecture () for a cellular Access Network (AN) () that allows the cellular AN operator to not only deploy its M2M Services Capabilities (SC) as an M2M SC Server () within its network domain, but to also use its M2M SC to work as an M2M SC Proxy () when communicating with an M2M Service Provider (SP) network () that also deploys an M2M SC Server (). The M2M SC Proxy in the cellular AN relays all signaling plane communications between an M2M device's/gateway's SC () and the SP's M2M SC Server. The M2M SC Proxy provides the cellular AN with an access to all of the Across-Layers (Transport and Service Layers) information needed for the M2M services enablement in the cellular AN. This proxy-based solution allows the cellular AN to serve all types of M2M SPs, and relieves the M2M SP from the need to support different cellular AN interworking interfaces.

The embodiments herein relates to a method in a transceiver () for enabling traffic you prioritizing in a wireless communication system (). The transceiver () is configured to transmit traffic to a first communication node (). The transceiver () transmits a message to the first communication node (). The message comprises an indicator indicating that the transmitted traffic tolerates a delay, enabling traffic prioritizing in the wireless communication system ().

Device for low priority handling

The embodiments herein relate to a method in a transceiver () for permitting access to a cellular communications system (). The transceiver () is configured to transmit traffic to a communication node (). The transceiver () receives a permission message from the communication node (). The permission message indicates permission to a group of transceivers to transmit an access request message indicating a request to transmit the traffic to the communication node (). The transceiver () determines whether the transceiver () is comprised in the group of transceivers having permission to transmit the access request message based on the received permission message.
