Abstract: A core network architecture for supporting an internet protocol based network is disclosed. The system includes a base station which is configured to convert a signal from a first network to an internet protocol network signal and send the converted signal through the internet protocol base network. The network also includes a gateway which is configured to receive the converted signal and deploy the converted signal through the internet protocol base network. In this sense, the internet protocol base network manages the call mobility and delivery of the signal. The base station in this disclosure may be a femto base station and the first network may be a code division multi-access (CDMA) network.

Abstract: A method and apparatus for even SLS code distribution is provided. SLS codes are assigned to signaling links that connect signaling nodes in a telecommunications network. The SLS codes determine a physical link used for routing messages in the network. Each link has a nominal set of SLS codes, which provide for even SLS distribution when all links are available. When a link is unavailable, its nominal SLS codes are reassigned to an available link. When an unavailable link is restored, the nominal SLS codes for the restored link are allocated to the restored link (302). Then a determination is made of the desirable number of SLS codes each available link should have for even SLS distribution (303). Any links that have more than the desired number of SLS codes for even distribution have the number of SLS codes assigned to that link reduced by allocating the excess SLS codes to a buffer (305, 308).
