A service management system that enables a subscriber of a mobile telecommunication system to modify aspects of his or her service plan and have the modification to the service plan take effect immediately. The subscriber enters a modification request to an aspect of a service plan. The modification request is verified against a set of rules that defines acceptable changes to the service plan. If the proposed modification to the service plan is a valid change, the change to the service plan is immediately propagated to a billing system and to other systems that implement the service plan. The subscriber is notified when the modification to the service plan is complete, and the subscriber is billed on a going-forward basis in accordance with the rate structure applicable to the plan.

Signaling from a mobile device is transparently tunneled through a cellular voice network to a Voice over Internet Protocol ('VoIP') core network so that multi-party calls, including conference calls and call waiting, can be managed entirely within the VoIP core network. The tunneled signals enable call control to be implemented in the VoIP core network and also establish a way to communicate requests, instructions, and call state. The signaling is transparent to the cellular network because that network does not receive and interpret the signaling. Instead, the cellular network's existing and unmodified control plane is repurposed by the mobile device by placing new, brief outgoing calls through the cellular network to the VoIP core network where the called party number (i.e., the caller-ID) encodes specific information. The VoIP core network immediately releases the new cellular call once the caller-ID is received and the encoded information is interpreted.

A mobile device utilizes a two-stage dialing solution when roaming on a visited mobile operator (MO) network to implement centralized routing so that a home network portion of a hybrid network is inserted into the path of outbound calls. A remote centralized routing (CR) service interoperates with a CR client on the mobile device. When a call is initiated to a remote party, the CR client calls into an arbitrary roaming routing number that is terminated in the home network. Once the call is connected between the mobile device and home network, the CR client sends a dialing string that includes a destination number of the remote party. The CR service calls the destination number and then bridges the calls to the mobile device and remote party to establish an end-to-end call path between the local and far ends of the call that traverses the home network.
