Techniques are provided to allow global roaming between different devices in different networks, using different protocols. A system may contain one or more protocol dependent logic servers (PDLSs), in which each PDLS is associated with a particular network/network protocol. The networks may comprise one or more wired telecommunications networks, wireless communications networks, or Internet-based networks. When a first PDLS receives an incoming, protocol-dependent message comprising a first protocol from a first network intended for a user currently registered on another network, the first PDLS converts the protocol-dependent message into an incoming, protocol-independent message and forwards it to another network element, such as a core logic server (CLS). The CLS processes the incoming, protocol-independent message, generates an appropriate outgoing protocol-independent message and forwards this message to a second PDLS. The second PDLS converts the outgoing, protocol-independent message to an appropriate outgoing, protocol-dependent message and forwards it to a second network operating using a second protocol. The conversion of incoming, protocol-independent messages into outgoing, protocol-independent messages eventually enables a link to be established between the two networks operating using different protocols.
1. A system for allowing global roaming between devices in wired and wireless networks, comprising a first protocol dependent logic server (PDLS) associated with each network, operable to:
receive a first, incoming protocol-dependent message in a first mobility management protocol originating from a first network;
convert the first, incoming protocol-dependent message to a first, incoming protocol-independent message which includes a value that indicates tasks to be performed within the system;
forward the first, incoming protocol-independent message to a first network module;
receive a first, outgoing protocol-independent message that includes routing information for a mobile user;
convert the first, outgoing protocol-independent message into an appropriate, outgoing protocol-dependent message in the first mobility management protocol; and
forward the appropriate, outgoing protocol dependent message to the first network.
