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 interval to an incoming request, and forwarding the request to such computing resource which belongs to the subinterval that contains the allotted random number.

Optimized resource management in core network elements

In a mobile communication networks system supporting IP Multimedia Subsystem, IMS, centralized services, there are provided measures for enabling/realizing an overlay implementation of a IMS centralized service network system taking into account a pool of network entities with different IMS centralized services capabilities. Such measures based on a IMS centralized-services applicability for a terminal requesting attachment and an IMS centralized-services capability of at least one switching entity out of a pool of switching entities which are configured to control radio resources for a same radio network area. In case of a mismatch between the IMS centralized-services applicability for the terminal and the IMS centralized-services capability of the switching entity the attachment request can be redirected to another switching entity out of said pool, which has a matching IMS centralized-services capability. Also, when receiving an attach request, a switching entity can be selected out of said pool, which has a matching centralized-services capability, and the requested attachment can be directed to the selected switching entity.

There are provided measures for enabling/realizing service continuity in a centralized service network system. Such measures exemplarily comprise detecting a deregistration request for deregistering a terminal with respect to a first switching entity from a registration in which the first switching entity is registered for the terminal as a contact point for centralized services, starting a waiting timer for waiting for a registration request for registering the terminal with respect to a second switching entity upon detection of said deregistration request, and re-registering the terminal in the registration such that the second switching entity is registered for the terminal as a contact point for centralized services upon detection of the registration request for registering the terminal with respect to the second switching entity before expiry of the waiting timer.

Service continuity in centralized service network system

Communication systems may benefit from various aspects of emergency call handing. For example, wireless communication systems may benefit from clean up with respect to a fast return feature applied to an emergency call using circuit switched fallback, without a location area update. A method may include identifying an emergency communication that is a circuit switched fallback communication of a user equipment. The method may also include configuring communications so that mobile terminated services work properly after completion of the emergency communication. More particularly, for example, a method may include determining in a network element that the emergency communication is a circuit switched fallback communication. The method may also include, when the emergency call is ended, avoiding invoking a fast return feature for the user equipment.

Embodiments of the invention include a method, apparatus, and computer readable medium related to mobility management. The method, apparatus, and computer readable medium may include, at least, receiving, at a network node, a terminating request from a user equipment. The method, apparatus and computer readable medium may further include, in response to receiving the terminating request, performing a restore data procedure, receiving a mobility management entity (MME) name from another network element in response to the restore data procedure, and registering the MME name to the subscriber data associated with the user equipment. The method, apparatus and computer readable medium may then include sending a paging request to the MME indicated by the MME name received from the other network element.

The present invention refers to a method, an apparatus and a computer program product for relaying CAMEL related messages in a telecommunication network, wherein received CAMEL related messages and corresponding subscriber data are analyzed (S), the received CAMEL related messages are translated (S) in non-Camel messages, the non-Camel messages are relayed (S) to a service delivery framework on the basis of the ana-lyzing result and non-CAMEL responses are received (S) from the service delivery framework. The non-CAMEL responses are re-translated into standard CAMEL operation responses (S), which are sent to initiator of the received CAMEL related message (S).
