A method is provided for enabling a requesting access node to use at least one radio frequency associated to at least one wireless communication network having at least one connected access node. Such method includes the following acts executed by a frequency access manager in the wireless communication network: retrieving at least one piece of data related to the at least one connected access node and related to the requesting access node; determining a mutual interference information between the requesting access node and the at least one connected access node in function of the at least one piece of data related to the at least one connected access node and related to the requesting access node; and transmitting, to the requesting access node of a frequency access data in function of the determined mutual interference information.

A Short Message Service (SMS) message is communicated to a mobile user equipment (MUE) over an Internet Protocol (IP) network using an IP communication. An SMS network includes a Short Message Service Centre (SM-SC), a gateway mobile switching centre (GMSC), the SMS network communicating SMS messages. An IP/SMS gateway communicates between the SMS and IP networks. A home location database maintains address data identifying a current location of a MUE. After interrogation by the GMSC, the home location database provides the GMSC an address of the IP/SMS gateway, stored in association with the subscriber identify number. The GMSC sends the SMS message to the IP/SMS gateway. The IP/SMS gateway retrieves an IP address corresponding to the mobile subscriber number pre-stored in an IP/SMS database associated with the IP/SMS gateway. The IP/SMS gateway communicates the SMS message to the MUE at the retrieved IP address via the IP network.

Telecommunications system for communicating a SMS message to a mobile user on an IP network

A telecommunications system provides a facility for communicating a Short Message Service (SMS) message to a mobile user equipment using a subscriber identity number when the mobile user equipment is communicating via an Internet Protocol network using an Internet Protocol (IP) communication being terminated on the IP network. The system comprises an SMS network including a Short Message Service Center (SM-SC), a gateway mobile switching center (GMSC), the SMS network providing a facility for communicating SMS messages, and an Internet Protocol/SMS (IP/SMS) gateway for communicating between the SMS network and the IP network. The system also includes a home location database for maintaining address data identifying a current location of a mobile user equipment. The gateway mobile switching center is operable in response to the SMS message to interrogate the home location database for an address to which the SMS message should be sent. The home location database is operable to provide the gateway mobile switching center with an address of the IP/SMS gateway, which has been stored in association with the subscriber identity number. The gateway switching center is operable to send the SMS message to the IP/SMS gateway. The IP/SMS gateway is operable to retrieve an Internet Protocol address corresponding to the mobile subscriber number pre-stored in an IP/SMS database associated with the IP/SMS gateway. The IP/SMS gateway communicates the SMS message to the mobile user equipment at the retrieved IP address via the IP network.
