Abstract: The invention comprises methods and arrangements for Policy Decision Point discovery in a roaming or handover scenario in an IP network (IN) comprising a plurality of network elements. The authentication function, e.g. an AAA-server, receives the address (ASPDP1) of the serving Policy Decision Point (SPDP1) associated to the user equipment, and stores the address of the serving policy decision point together with the local address of the user equipment. The authentication function sends the address of the serving policy Decision Point to the Home Agent so that the Home Agent can forward the address of the serving policy decision point to the anchor Policy Decision Point and so that the anchor Policy Decision Point can contact the serving policy decision point by using said address of the serving Policy Decision Point.

Abstract: The present invention relates to a method and apparatus for requesting a transport policy for a bearer of a session in a communications system (100) A transport policy requesting node (500) according to the invention comprises an event handling mechanism (505) adapted to detect a triggering event triggering the selection of a transport policy for the bearer of a service; a transport policy selection mechanism (525) adapted to select a transport policy and transmit a policy request indicative of the transport policy to a policy decision function, and a context information handling mechanism (515, 520) adapted to receive information relating to a context relevant to the service. The context information can be used as a trigger for the selection of a transport policy, and/or as a basis for the selection of a transport policy.

Abstract: The present invention provides methods, an application node (104, 26, 300), a policy node (108, 24, 400), a system for service delivery control related to access technology types and in particular for service delivery control based on allowed access technology types. Based on radio access technology types as defined by an application node related to a service provider as communicated to the policy node over the inter node interface Rx (106), and an radio access technology type with which a mobile phone (102, 22) communicates on at the moment, a determination is made as to whether the radio access technology type with which the mobile phone communicate son is among the allowed radio access technology types or not. If it is not, the current access technology type may be updated such that there is a match between the allowed radio access technology type and the current radio access rate.

Abstract: The invention comprises methods and arrangements for Policy Decision Point discovery in a roaming or handover scenario in an IP network (IN) comprising a plurality of network elements. The invention comprises methods and arrangement in an user equipment for receiving the address of the serving policy decision point and sending to the Home Agent a registration request comprising the local IP address of the user equipment so that the home agent can register the local IP address. The registration request will also comprise the address (ASPDP1) of the serving policy decision point (SPDP1) so that the Home Agent can forward the address of the serving policy decision point to the anchor Policy Decision Point and so that the anchor Policy Decision Point can contact the serving policy decision point by using said address of the serving Policy Decision Point.

Abstract: A method and an arrangement in a service assurance module for controlling service level agreements for communication services in a mobile services access network. A network performance rule is created for a service level agreement, and is based on an associated performance indicator indicating the current network performance with respect to the fulfillment of the service level agreement. The performance indicator is then monitored, and the network performance rule is evaluated on a regular basis based on the performance indicator. If the network performance rule is not satisfied, an agreement violation is registered and/or measures are' taken to improve the network performance.

Abstract: A method and an SLA portal (204) in a communication network (202), for establishing an SLA (Service Level Agreement) between a third party content provider (200) and an operator of the network for ensuring network resources needed for delivering a specific service. When an SLA request (2:1) is received from the content provider for the service, at least one viable predetermined SLA is retrieved (2:2) from an SLA database (206) holding a plurality of predetermined SLAs. The retrieved at least one viable SLA is then sent (2:3) on offer to the content provider, optionally together with an assigned service identifier. Thereby, the process of establishing the SLA is automated and any physical meetings and correspondence otherwise can be avoided to save time and costs.

Abstract: A method and arrangement for establishing a packet-switched multimedia session for a mobile terminal (A) in communication with another party (B), wherein a primary PDP (Packet Data Protocol) context has been activated in a mobile network for the mobile terminal. Information on the forthcoming session is received which has been negotiated and agreed between the communicating parties. It is then determined whether any network resources providing a required QoS are needed for the session, and whether a secondary PDP context is to be activated for the mobile terminal and the forthcoming session. If network resources are needed and a secondary PDP context is to be activated, the activation of said secondary PDP context is triggered.
