摘要： There is described a method for optimizing the distribution of data objects between caches in a cache domain of a resource limited network. User requests for data objects are received at caches in the cache domain. A notification is sent from each cache at which a request is received to a cache manager. The notification reports the user request and identifies the requested data object. At the cache manager, object information including the request frequency of each requested data object and the locations of the caches at which the requests were received is collated and stored. At the cache manager, objects for distribution within the cache domain are identified on the basis of the object information. Instructions are sent from the cache manager to the caches to distribute data objects stored in those caches between themselves. The objects are classified into classes according to popularity, the classes including a high popularity class comprising objects which should be distributed to all caches in the cache domain, a medium popularity class comprising objects which should be distributed to a subset of the caches in the cache domain, and a low popularity class comprising objects which should not be distributed.

摘要： A method is implemented in a network element to generate quality of experience (QoE) metrics for hypertext transfer protocol (HTTP) sessions over a network between a user device and an HTTP server. The QoE metrics are based on detecting premature termination of a download process that indicate low QoE. This QoE metric data can then be utilized by network administrators or service providers to adjust network characteristics to improve the QoE or to offer changes in services to a customer that would improve the QoE.

摘要： The present invention relates to method and means for a system initiated subscriber information redistribution in order to achieve a load redistribution within a pool of core network nodes. The subscribers, that are affected by the redistribution, are determined by the bit values in their TMSI's. These specific TMSI's are then arranged to be treated as invalid by the cellular system. Messages etc. from subscribers with invalid TMSI's will be “trapped” in the cellular system and the subscriber information that belongs to these subscribers will be redistributed to new core network nodes.

摘要： A method of allocating user plane nodes to a connection being established across a packet core network. The method comprises maintaining at a Domain Name System, DNS, server, one or more DNS resource records for each available user plane node or group of neighboring user plane nodes, a DNS resource record containing a measure of a route quality or cost between the associated user plane node(s) or group(s) and each of one or more further user plane nodes or further groups of neighboring user plane nodes of the packet core network to which said associated user plane node(s) or groups is(are) connected. A connection establishment request is processed at a mobility management control entity within the packet core network, with a DNS query being sent to a DNS server, the query containing one or more user plane node selection criteria. The query is received at the DNS server and, on the basis of the or each criterion, one or more DNS resource records satisfying the criteria/criterion identified. At least said measure of route quality or cost of the identified DNS resource record(s) is returned to said mobility management control entity. The measure(s) of route quality or cost of the identified DNS resource record(s) is received at the mobility management control entity, and the measure(s) used to allocate a user plane node or nodes to said connection.
