<p>The present invention relates to a method of requesting and sending at least one authentication vector (AV) between an HSS (10) and at least one HLR (21, 21', 21"), said HSS being connected to at least one IMS telecommunications network, and said HLR having an authentication centre (22, 22', 22") AuC configured to generate AVs, comprising the steps of:
- the HSS receiving through the IMS network a first message requesting at least one AV to authenticate a subscriber X who requests an IMS service, said subscriber being identified by his or her IMPI identity,
- the HSS processing said first message and sending a second message to the HLR,
- the HLR determining if the AV request is from an IMS service or from a GSM/GPRS or UMTS service,
- said AuC generating at least one AV with a key associated to the subscriber, said key being a Ki associated to the IMPI identity if it is an IMS service, or a Ki' associated to an IMSI identity if it is a GSM/GPRS or UMTS service,
- the HLR generating a third message containing said AV and sending it to the HSS,
- the HSS processing said third message and the HSS sending a fourth message containing said one AV to the IMS network.</p> |
