Abstract: The present invention addresses method, apparatus and computer program product for resource management within a distributed system in a core network element, comprising organizing computing resources of the core network element into sets, wherein a first set is always active, setting an upper threshold and a lower threshold for the load of the sets, wherein the sets in operation are loaded as long as the average load of the sets in operation reaches the upper threshold, and when the upper threshold is exceeded, a new set is activated, whereas, when the load thereof falls below the lower threshold, the last activated set is deactivated, assigning a priority number to each set, segmenting an interval of random numbers for randomizing a request distribution in subintervals which are allocated to the computing resources of the active sets, wherein the length of each subinterval is determined based on the priority number of the set of the respective computing resource, and allotting a random number out of the inte

Abstract: A method in a communications system for handling responses to messages includes a step of sending a message from a first party to a second party. A response to the message is sent, with the response including at least one parameter in breach of a policy for a communication between the first party and the second party. A network controller detects that the response includes at least one parameter breaching the policy. The at least one parameter is modified to be consistent with the policy.

Abstract: A method for providing an implicit emergency registration set is disclosed. The method can include initiating an identifier selection procedure. The method can also include identifying whether a user has a dedicated emergency telephone uniform resource identifier (tel URI), and, if so, selecting it. The method can further include identifying, when the user does not have a dedicated emergency tel URI, whether the user's internet protocol (IP) multimedia private identity (IMPI) is known. The method can additionally include identifying, when the user's IMPI is known, whether the user's IMPI has a non-shared tel URI, and, if so, selecting it, but otherwise selecting a tel URI of the user's IMPI. The method can also include identifying, when the user's IMPI is not known, whether a shared tel URI is available, and selecting it if it is, otherwise selecting a tel URI from a non-shared set.

Abstract: An apparatus and method of processing a service request in an IP multimedia core network is provided. The method includes the steps of receiving a service request initiated by a first user, for a second user, forwarding the received service request to a unit for processing the service, receiving a processing result from the processing unit, and determining, on the basis of the received processing result, whether the service request processing for the second user is to be stopped.

Abstract: A method of allocating one of a plurality of call state control functions to a subscriber, the method comprising: sending registration requests to the plurality of call state control functions; storing information regarding the availability of the call state control functions in response to unsuccessful registration requests; and determining a call state control function for the subscriber in dependence on said stored information.

Abstract: A method for tracing a session or call in a network environment, comprising the step of transmitting a trace invocation from a control plane network element to another control pane network element or a user plane network element. According to a first aspect, a trace report is generated in the S-CSCF of the called party. This overcomes the lack of being able to provide detailed information about the interworking between the User Equipment (UE) and the IMS, in setting up IP multimedia sessions. According to a second aspect trace reports are generated in all the network functions involved in session setup.

Abstract: A communication system and a method wherein a subscription can be associated with a plurality of public and private identities are provided. According to one embodiment, the method includes the steps of storing in a user information storage information of the relations between the identities and of a control entity in which at least one of the public and private identities is registered, and allocating the control entity to a further registration based on the information stored in the user information storage.
