Claims
- 1. A method for controlling wireless network traffic, comprising:
determining when a roaming mobile station initiates a registration attempt with a non-preferred network; and causing the roaming mobile station to initiate a registration attempt with a preferred network.
- 2. The method of claim 1, further comprising determining what network the mobile station is currently registered with.
- 3. The method of claim 1, further comprising preventing the mobile station from succeeding in the registration attempt with the non-preferred network.
- 4. The method of claim 1, wherein the registration attempt with the non-preferred network is completed, the method further comprising:
determining that the mobile station is registered with a non-preferred network; and periodically causing the mobile station to reinitiate a registration attempt with a preferred network.
- 5. The method of claim 1, further comprising:
determining whether the mobile station should be moved to another network; and updating files on the mobile station, including a preferred provider list.
- 6. The method of claim 1, further comprising:
determining whether the registration attempt with a non-preferred network is allowed to succeed; if the registration attempt is not allowed to succeed, rejecting the attempt.
- 7. The method of claim 6, wherein rejecting the attempt comprises sending a recognized transaction to the mobile station that aborts the attempt.
- 8. The method of claim 6, wherein rejecting the attempt comprises causing a transaction time out.
- 9. The method of claim 6, wherein rejecting the attempt comprises modifying a message to restrict roaming by the mobile station.
- 10. The method of claim 1, further comprising determining whether a roaming mobile station is engaged in a voice or data session.
- 11. The method of claim 1, further comprising determining whether a roaming mobile station is in an automatic network selection mode or a manual network selection mode.
- 12. The method of claim 1, further comprising invoking an Update Location message on demand.
- 13. A method for directing a network entity to a particular network, comprising:
detecting a roaming network entity is registering with a visited network; detecting the visited network is a non-preferred network; and initiating a redirection message to the network entity that causes the network entity to search for a preferred network.
- 14. The method of claim 13, wherein detecting the roaming network entity is registering with a visited network includes tapping a message and determining at least a mobile country code (MCC) and a mobile network code (MNC).
- 15. The method of claim 14, wherein the message is an Update Location message.
- 16. The method of claim 13, further comprising:
sending the redirection message to an over-the-air (OTA) server; encrypting the message; and forwarding the message to a short message service center (SMSC).
- 17. The method of claim 13, further comprising:
determining whether the network entity includes a Subscriber Identity Module (SIM) toolkit application (STK); and if the network entity includes an STK, initiating redirection with the STK.
- 18. The method of claim 13, further comprising:
if the network entity includes an STK, determining whether a Public Land Mobile Network (PLMN) list is on the SIM; and if not, forwarding a PLMN list to the SIM.
- 19. The method of claim 13, further comprising:
in response to the message, initiating redirection procedures; and updating information on the SIM, including
a home PLMN search time period; a PLMN selector file; and a location information file.
- 20. The method of claim 13, further comprising, in response to the message, issuing a RUN AT+COPS command to select a specific network.
- 21. A system for directing wireless network traffic, comprising:
a network operator backend, including an OTA interface; and a traffic redirection network entity, wherein the traffic redirection entity communicates with a mobile station to direct registration with a particular network when the mobile station attempts registration with a non-preferred network.
- 22. The system of claim 21, wherein the traffic redirection network entity comprises a traffic redirection node, a traffic redirection roaming probe, and a traffic redirection application.
- 23. The system of claim 22, wherein, in a passive mode, the traffic redirection network entity monitors a signaling link between a home network and an SS7 signaling network to determine a network the mobile station is currently registered with.
- 24. The system of claim 22, wherein, in an active mode, the traffic redirection node is in a signaling path 314 between a visited location register in a visited network and a home location register in a home network that determines a network the mobile station is currently registered with.
- 25. The system of claim 22, wherein, in an active mode, the traffic redirection node is in a signaling path 314 between a visited location register in a visited network and a home location register in a home network.
