This webinar sponsored by iBasis will address the following:

  • The business need for quick introduction of LTE roaming

      This Q&A has now closed, thank you for your questions.

    • Rodrigo June 19, 2012 at 2:33 pm

      Hi Ajay, do you believe roaming between different technologies (GSM, HSPA) and Duplexing modes (TD-LTE /FDD-LTE) will be feasible in the short time? And for VoLTE and CS (GSM) will still remain?

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 3:14 pm

        Yes – the chipset’s manufacturers expect to support both TDD and FDD together by mid 2013. The handsets will also support existing technologies as well.

    • laurent Dubesset June 19, 2012 at 9:42 am

      Ajay, assuming that most of the first LTE roamign agreement will be with operators with whom we already have bilateral roaming agreements for GSM, GPRS, 3G, do you think this is possible to have a LTE hubbing agreement with them?

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:48 am

        I don’t why both bilateral and hubbing models can’t co-exist.

    • Gisbert Feichtinger June 19, 2012 at 9:36 am

      Your offer of a LSX, LTE signalling exchange, is this somewhat an alternative to GSMA IPX?!

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:41 am

        They are both needed – LSX for signaling riding the underneath IPX – we also can send the media over the IPX..

        • Ajay Joseph
          Ajay Joseph June 19, 2012 at 9:44 am

          Just as a clarification – the LSX is a service for signaling over the iBasis IPX. The iBasis IPX can transport multiple-services including voice, SMS, GRX, LTE Signaling, HD Voice among others.

      According to you, What are the 3 key challenges for LTE roaming ?
      thx

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:38 am

        1. Frequency harmomization
        2. Interoperability of protocols
        3. Development of LTE hubbing networks

        • Gabriel June 19, 2012 at 9:56 am

          Why can’t the operators use GRX to exchange LTE signaling?

          • Ajay Joseph
            Ajay Joseph June 19, 2012 at 10:01 am

            The question is on scale – you will need to setup more than transport – its about interoperability, supporting transactions per second, interworking with legacy networks etc.

    • laurent Dubesset June 19, 2012 at 9:30 am

      When do you expect LTE roaming to start in Europe? Before the EOY of early next year? Sorry if you answer during the webinar.

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:32 am

        We expect the parts of Europe advanced in LTE to start in 2013.

    • Keith Yam June 19, 2012 at 9:29 am

      Thanks Ajay. What are the major differences between roaming in LTE (data) and VoLTE ?

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:34 am

        The VoLTE which uses IMS has real-time components to the traffic flows and will require local break-out for quality reasons.

    • laurent Dubesset June 19, 2012 at 9:21 am

      Do the LBO implementations include S9 and Gy interfaces between the HPLMN and the VPLMN for QOS control and real time retail billing?

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:25 am

        The S9 yes, there are soem models also for the Gy. we should discuss.

    • Paul Hemming June 19, 2012 at 9:20 am

      Hi Ajay, are you liaising with the marketing teams in the operator community or just the network engineering/interconnection groups?

      Good luck wit the sandbox initiative!

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:24 am

        We are liaising with both the commercial and tech teams. The response has been great. Thanks

    • Frank Zandee June 19, 2012 at 9:20 am

      Hi Ajay, can the home operator, despite the local breakout for data services, still be fully in control of its customers? E.g. for monitoring data usage/ EU Regulation data cut off limit

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:22 am

        Yes – we lets contact later – we have something for this

    • raymond bouwman June 19, 2012 at 9:17 am

      you said that -other than in UMTS where most of traffic is sent home – in LTE local break out will become apparent. Why do you think that will happen?

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:19 am

        We have already seen test implementations of Local break out in Asia. We expect production versions sometime next year

    • Nedim Hodzic June 19, 2012 at 9:13 am

      Would also GTP-C be included in IPX or transformed to Diameter over time? Shall IPX handle all legacy and new protocols, including TDM based and GRX?

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:17 am

        IPX can handle both the TDM versions of protocols as well as GRX. The issue with the GRX is the lack of QoS especially for real-time services – this will need to migrate to IPX.

    • Keith Yam June 19, 2012 at 9:09 am

      Hi Ajay, when do u expect the LTE spectrum harmonization could be achieved ?

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:21 am

        We expect chipset makers to come out with chips to handle multiple frequencies to facilitate roaming by middle next year.

    • Jim Dev June 19, 2012 at 8:43 am

      Hi Ajay. To what extent will the current high roaming tariffs inhibit the uptake of LTE roaming?

      • Ajay Joseph
        Ajay Joseph June 19, 2012 at 9:06 am

        High Tariffs will inhibit the uptake of LTE services – especially as LTE is all IP as in all data. The good news is that there is considerable pressure from the regulator in various countries and regions to put downward pressure on bringing lower tariffs to the end consumer.
