  • Blackberry is a very popular GPRS-based service used all over the world for email/data access. In both Europe and US, and now in many ASPAC countries, local mobile operators offer Blackberry service. So the subscriber can i access both voice and blackberry email/data services on the same phone or wireless mobile communications device.
  • SIM card modification devices to support two SIM cards in a single mobile wireless device.
  • One SIM card is from the overseas operator that offers the roaming Blackberry-type service and the other is from the LPMN.
  • the problem is that only one SIM card can be active at a time. If the overseas card is active, the subscriber cannot receive or make calls or SMS on the local number. Voice calls and SMS will result in expensive roaming charges. If the local card is active, the subscriber cannot use the Blackberry devices to send or receive emails or information via Blackberry. [0008]
  • the present invention comprises a novel way to solve that problem. It allows both the SIM cards (or rather, both the service subscriptions) to be logically active. It does not even require the subscriber to use the overseas card to get both services. Hence there is no need for handset change or special accessories to hold both cards.
  • the basic idea is to automatically latch on to the data subscription whenever the user latches on to the local voice subscription network.

  • the LPMNSIM should also have international dialing capability if the OPMN SIM supports international dialing
  • the Blackberry subscription details will be captured and linked up with the voice subscription details.

The user will be able to use the services seamlessly. He will be able to receive phone calls and SMS while in a data channel communications session. [00016] In addition, if the OPMN profile can make roaming international calls and the LPMN subscriber wants to do the same, then the LPMN subscription also should support international dialing.

  • Figure 1 shows the Signal Packet Gateway Network Architecture.
  • the LPMN operator reserves a special range of IMSIs for subscribers opting for unified Blackberry data and mobile voice service.
  • An LPMN subscriber must be issued a new local SIM card from this range although they don't need to change the original local MSISDN if a local card was already subscribed.
  • the subscriber should also have a local GPRS subscription plan, which can be of a prepaid or postpaid sort.
  • the LPMN will need to implement a subscription process to capture the mapping between the LPMN subscription profile (IMSI, MSISDN) and the OPMN data subscription explicitly from subscribers. This can be implemented by providing the overseas MSISDN or the overseas SIM to the operator. This mapping is not stored in the HLR but is stored in the database of the SPG.
  • IMSI LPMN subscription profile
  • MSISDN MSISDN
  • This mapping is not stored in the HLR but is stored in the database of the SPG.
  • a special range IMSI for the LPMN SIM card allows the operator to set a special E.214 route for all these IMSIs, thereby forcing all their GSM and GPRS location updates to be routed through the SPG 11 and not directly to the LPMN HLR 10.
  • the SPG 11 relays the location updates to the LPMN HLR 10, but also performs an automatic registration into the OPMN HLR 15 for data service.
  • the LPMN also provides certain ISUP Loopback circuits or IN triggers between the LPMN MSCs 13 and the SPG 11.
  • the purpose of this feature is to allow the MT calls/SMS on the OPMN number to pass through the SPG 11 to account for billing CDR and to handle OPMN voicemail notification especially for the LPMN subscriber.
  • the special IMSI range is aimed at allowing the billing system to treat local MT CDRs of the range separately since it may in fact be a MT roaming call/SMS when the OPMN number is called/SMSed. In the case of MT roaming CDR, MT TAP with the corresponding overseas IMSI will need be produced.
  • the Blackberry data service is really on the OPMN IMSI while the LPMN SGSN 14 has the local IMSI record
  • the special IMSI range will also allow the billing system to treat local SGSN CDR of the range differently.
  • the LPMN will also need to update its DNS server to map local Blackberry APN to the SPG 11 which can then establish GPRS context with the OPMN GGSN 17.
  • SIM Single IMSl, Multiple MSISDN
  • the extension is to support both local and overseas profiles, not just local profiles.
  • the main idea in this framework is to route location updates through the SPG. This gives the SPG the chance to automatically sign on to the second subscription, and also to adjust things such that the SPG is in the path for various call and SMS scenarios. It primarily does this by providing its own address as the serving MSC and VLR address, instead of the real MSC and VLR addresses. This allows it to be the recipient of PRN messages from the HLR and MT-FSM messages from SMSCs, which in turn allows it to control incoming calls and SMS services to the phone. [00035] Besides being in the path for the PRN messages, the SPG also modifies the MSRN in order to be in the call path itself. As mentioned earlier, this allows the SPG to provide billing support.
  • the SPG functions like a virtual
  • the E214 SCCP message is redirected to the SPG. If the location operator is other than the LPMN, SPG simply relays the message out to the real LPMN HLR without further involvement. Only if the location operator is the LPMN, all the following will be applied.

When a new location update comes again, the combined GSM subscription profile from local and overseas will again bring back the international call capability.
