  • 1.  Best TMF API for Pre-provisioning of registration of SIM's

    Dear All,

    Need your quick input/guidance on using correct TMF API for SIM's registration. It's regarding pre-provisioning or registration of SIM's inventory at core network i.e IMS network HSS, AOTA etc. so before handing over to subscriber we do need to pre-provision or register respective IMSI , ICCID etc. range on network along with its authentication key and all so which TMF API can be used . Is it TMF664 or TMF702 etc. ?

    Because later when actual customer or subscriber we reserve respective MSISDN and associate its ICCID,IMSI to activate service, plan offers etc. via PCRF, HSS then we will be using TMF 641-640 for respective activation of MSISDN, IMSI, ICCID at HSS, PCRF for policy and profile definition.

    Kindly guide if will before when we get IMSI ranges and all from SIM's vendor and all with specific network specification and we need to get those registered on HSS, OTA etc. as a pre-requisite with its various authentication and network profile keys which TMF API can be best suited. If its TMF 664 how it can be used as I am unable to map MSISDN, ICCID, IMSI etc. ranges with resource function and its registration parameters with given operations like heal, scale, migrate or for activation of resource.

    Thanks !!!

    Hi Mahesh

    If you are talking about pre-provisioning of an individual SIM, presumably TMF702 would be the correct API, Resource Activation. TMF664 is specifically for resource functions, and I don't think a SIM is that. But maybe @Vance Shipley could weigh in here.

    There is no concrete model in the TMF Open API for SIM resource and its friends, so all the items that you mention would be characteristics on the SIM resource. It will be your responsibility to populate the characteristic values based on what you get from your SIM manufacturer and of course the specific needs of your network equipment.

    If you need to do bulk pre-provisioning, you'll have to set up a process that invokes the TMF702 POST one by one for each item in the bulk. Or use some bulk load that doesn't involve TMF Open APIs.

    Hope it helps

    Thanks @Jonathan Goldbergfor your quick response and inputs. Even we were thinking of 702 could be most suitable. Just one query can we use and execute this API directly between source and destination we need to generate some 641-service order or 652 resource order and against that logically we can map RFS to execute 702 API. Just thinking from modelling of API and SID accordingly for resource/ service etc. so that subsequently when customer /subscriber order comes for actual service plan activation in HSS, PCRF etc. then against 641 we can use 640 and also will have respective service inventory associated against earlier created resource inventory against 702.

    Have a look at the proposals in 

    TMFS008 Use Case: Service and Resource Order Management for Postpaid Mobile Subscribers v3.2.0 – TM Forum

    Note this member only document at the moment.

    It describes the modelling as per Vance description below and show the sequence chart for ordering and provisioning including which API's to use.

    The big picture would be that a universal integrated circuit card (UICC) based SIM is a Physical Resource while an eSIM is a Logical Resource. In both cases they contain one or more Logical Resources representing applications, chiefly USIM but possibly ISIM and others.

    If you are managing the SIM/eSIM distribution channels you would want to represent those Physical/Logical Resources as their own managed entities.

    A USIM or ISIM would most accurately be represented as a instance of Installed Software (TMF730) as it is technically an application running on an embedded computer (UICC) which exposes an API via Resource Functions (e.g. AKA Challenge). I am not however going to suggest that you do that.  Those are all subclasses of Logical Resource and you may just manage the USIM application as one Logical Resource.

    So with that said you may use TMF702 for activation of a (U)SIM if the system producing the API is intended to handle activation through interaction with HSS, etc..
