Abstract:
1. A method of performing monitoring-continuity in case of number portability in a telecommunication system, comprising: requiring, by a monitored user, number portability from an operator of a donor network to an operator of a recipient network and receiving at an agency controlled receiving entity a number portability event—temporary address including information related to a user's ported identity and a user's new identity, wherein the agency controlled entity is equivalent to a monitoring function and the donor network is configured to intercept the user based on the user's ported MSISDN as target identity, the method further comprising the step of receiving at an Interception Control Element in the recipient network, an order to intercept the user based on the user's temporary MSISDN set as target identity, further comprising step: detecting lapse of a time period; setting a proper network configuration for the user's ported MSISDN so that any call to the user's ported MSISDN is routed to the recipient network receiving at the monitoring function a number portability event—completion receiving at the Interception Control Element in the recipient network, an order to remove interception of the user's temporary MSISDN and receiving at the Interception Control Element (MSC-R) in the recipient network, an order to intercept the user wherein the user's previously ported MSISDN is set as target.
