Ciber min uimid verification process

CIBER MIN/UIMID verification process

  • CIBER file format, ESN/IMEI/MEID field, can only contain one mobile identity, either ESN, UIMID, pESN, MEID.

  • KDDI verifies if MIN/UIMID in received CIBER record is a valid MIN/UIMID stored in our customer database to avoid wrong charge.Typical cases this verification process detect are: Case 1: Some markets direct any calls from negative roamers, e.g. terminated handset, to their call center and bill the call. Case 2: Some markets allow calls to specific numbers even if they are made from negative roamers. Case 3: By wrong MSC configuration, there may be markets where pre-call validation is not in place.

  • In such cases, especially you re-use MIN, a customer, who is assigned a re-used MIN, is billed incorrectly unless such verification is in place.

Min uimid verification process in meid era

MIN/UIMID verification process in MEID-era

  • Once Serve NW supports MEID(IS-2000 Pre-Rev.D), MEID can be retrieved via newly defined "Status Request" message. (see 3.3.14 in A.S0014)

  • Now, your billing system has a choice. Either you put MEID or UIMID into CIBER ESN/IMEI/MEID field. If Serve puts MEID, Home cannot tell UIMID value, which result in giving up CIBER MIN/UIMID verification process.

  • As KDDI wants you to put UIMID to keep the verification process,let us hear your implementation plan and opinion about this.Q1. As Serve, which will you put into CIBER, MEID or UIMID(pESN) ?Q2. As Home, which do you prefer to receive, MEID or UIMID(pESN) ? And why do you prefer it ?

    Please email your answer to me at [email protected] Thanks !!

Thank you.


Should we put meid or uimid onto ciber

[FYI] Presentation Material at IRT Miami 2006

Should we put MEID or UIMID onto CIBER ?

  • While StatusRequest, introduced w/ IS2000 Pre-Rev.D, allows Serving MSC to obtain MEID in addition to UIMID, CIBER can only contain either one of them. CIBER MIN/UIMID verification can only be maintained if Serve puts UIMID into CIBER rather than MEID.
