The method comprises the wireless device determines that two or more Packet Data Unit, PDU, sessions established within the wireless system that are associated to at least one Data network identified by a Data Network Name, DNN, or to at least one Single Network Slice Assisted Information, S-NSSAI, should be released and transmits to a control entity of a core network, a Non-Access-Stratum, NAS, message indicating one of the at least one DNN or the at least one S-NSSAI for which the corresponding PDU sessions should be released all at once with a single message.

UE controlled PDU sessions on a network slice

Apparatuses and methods for IMS slicing-enabled IMS voice sessions between autonomous machines and/or voice related services. A method for a first user equipment, UE, for authenticating the first UE is provided. An alert voice call is communicated to a second UE for initiating authentication of the first UE. A voiceprint of a user for the authentication of the first UE is communicated, via an IMS slice, and based at least in part on an analysis of the voiceprint, an authentication success message or an authentication fail message is received. A method for an Application Server includes receiving, via an IMS slice, a voiceprint of a user. The voiceprint is compared to a voiceprint sample. The voiceprint sample is associated with the first UE. Based at least in part on the comparison, an authentication success message or an authentication fail message is communicated.

A method for managing a charging operation in a communication network is disclosed. The method comprises receiving a content specification identifying content, vendors and a condition relating to charging the vendors for provision of the content to a UE. The method further comprises creating a charging policy for provision of the content, which specifies division of charging for provision of the content to a UE between the vendors in accordance with the condition, receiving, from a UE, a request for provision of content over the network and retrieving a charging policy corresponding to the requested content. The method further comprises creating a charging entry for provision of the requested content, the charging entry dividing charging for provision of the requested content between vendors identified in the retrieved charging policy and a subscriber account associated with the UE in accordance with the retrieved policy.

Also disclosed is a method, in a resource management function, for managing resources in a communication network comprising a plurality of M2M devices. The method comprises receiving, from a monitoring function, a calculated impact upon the communication network of completion of an action by M2M devices subject to a user instruction specifying the action (), and adjusting resource allocation within the network according to the calculated impact (). Also disclosed are a monitoring element, a resource management element and a computer program product.

Methods and apparatus for monitoring and managing resource usage in a communication network

The present disclosure relates to a method performed by a network node () in a communication network () comprising a plurality of communication devices (), for finding temporally connected connection patterns of the communication devices in the network. The method comprises identifying signalling between the communication devices during a predefined time duration to form a main communication graph in which the plurality of communication devices are nodes. The method also comprises partitioning the main communication graph for a time period comprised in said time duration to capture temporally connected signalling between some of the communication devices as illustrated in the main communication graph in a partitioned communication graph. The method also comprises forming at least one subgraph from the partitioned communication graph, comprising m nodes corresponding to m communication devices of said some of the communication devices. The method also comprises constructing a binary vector of the subgraph over the time period divided into a plurality of sampling periods corresponding to components in the vector such that, for each component in the vector, the component value is set to '1' if, in accordance with the subgraph, signalling occurs between at least two of the m communication devices during the sampling period corresponding to the element, and the component value is otherwise set to '0'. The method also comprises testing whether the signalling between the different m communication devices used for constructing the binary vector is temporally connected by checking that the number of consecutive '0' element(s), if any, between any two &#x201c;1&#x201d; elements is less than a predefined &#x394;T.
