Abstract: A method for associating partial durations of a voice service session provided via a packet-switched network to parties of the voice service session, wherein the parties comprise a first party and a second party, and wherein dedicated network resources are assigned and/or released intermittently during the voice service session is disclosed. The method comprises invoking, when the voice service session is ongoing, a hold or temporary disconnect of the voice service session by either of the first and second party, storing a Session Description Protocol, (SDP) Offer as negotiated between the first and second party in a storage for a first time duration, and associating, to the party who invoked the hold or temporary disconnect of the voice service session, an intermediate partial duration of the voice service session that starts when the hold or temporary disconnect of the voice service session was invoked.

Abstract: A method performed by a gateway node, for handling an incoming call to a first user equipment is provided. The gateway node serves the first user equipment in a terminating network. The first user equipment is a called party of the incoming call. The gateway node obtains (402) information about whether or not the incoming call relates to a subscriber number that is comprised in a registered set of subscriber numbers registered by the first user equipment. When the incoming call relates to the registered set of subscriber numbers, the gateway node converts (403) the incoming call to an Enhanced Multi-level Precedence and Pre-emption service, EMLPP, call in the terminating network at the gateway node. The EMLPP call is a prioritized call achieving priority features over other calls in the terminating network. The priority features comprises:—Faster Call Setup Time-Queuing Capabilities-Precedence Capabilities-Pre-emption Capabilities.
