Abstract: A method and apparatus for use in a communication network. A node receives voice data relating to a voice sample of a subject and an identity of the subject. The voice data is associated with the identity of the subject and stored. A speech sample is subsequently received from a traffic node, the speech sample having been obtained from a telecommunications session. A comparison is made between the stored voice data and the speech sample, and a determination is made to check whether the speech sample is likely to belong to the subject. If so, then a message identifying the subject is sent towards an LEMF node. The LEMF node can then initiate lawful interception of the telecommunications session. The node allows a target subject to be identified by a voice sample, which makes it much more difficult for a target subject to avoid lawful interception by, for example, using a different device to make a call.

Abstract: A method of controlling paging flow in a network for cellular communications is described, which comprises the steps of: at a control node, receiving a request for paging a mobile station; determining a location area in which the paging shall be performed; checking whether the number of paging transactions which are ongoing for the location area is lower than at least one maximum number of ongoing paging transactions allowed for the location area; after a determination that the number of ongoing paging transactions is lower than the maximum number, updating the number of ongoing paging transactions for the location area and processing the paging request. Preferably, if the number of ongoing paging transactions is not lower than the maximum number, it is checked whether the paging request is a particular LCS transaction and, if so, the request is placed in a buffer and served with priority as soon as the number of ongoing paging transactions returns to be lower than the maximum number.
