Abstract
Description
NPL 2: 3GPP TR 33.abc (S3-131125), "Study on Security for WebRTC IMS Client access to IMS; (Release 12)", V0.1.0, 2013-11
This exemplary embodiment proposes a static IMS ID allocation to the WWSF per webRTC identity. Fig. 1 shows the principle of the identity binding.
In this exemplary embodiment, the WWSF is using a pool of IMS IDs received from the HSS of the IMS operator. The idea behind is that the webRTC service provider does not assume that the webRTC user has an own IMS subscription so the webRTC provider holds a pool of IMS subscriptions that can be assigned to the webRTC IMS client (WIC) on demand. The architecture is shown in Fig. 3.
At some point in time,
In this exemplary embodiment, a third party authentication and authorization server is used, which is trusted by the webRTC service provider as well as the IMS operator. The architecture is shown in Fig. 8.
At some point in time,
Current webRTC TR 33.abc describes two different solutions for the authentication of the webRTC IMS Client in IMS., based on the assumption that the user has a subscription with an individual IMPU and uses an IMS authentication mechanism (e.g., IMS digest) to authenticate with IMS. This assumption limits the usefulness of the webRTC interworking feature extremely, since there is no point in using webRTC communication if the user has an IMS client and can setup IMS sessions without webRTC.
- The eP-CSCF verifies any UE authentication performed by the WWSF and performs Trusted Node Authentication (TNA), as defined in TS 33.203, in IMS for UEs already authenticated by the WWSF.
- For Web authentication scenarios, the eP-CSCF verifies that the WWSF is authorized to allocate IMS identities that it assigns to a WIC.
- The eP-CSCF performs IMS registration for WICs using either IMS or Web authentication schemes.
It is proposed to add the following text into the webRTC TR 33.abc.
The WWSF is using a pool of IMS IDs received from the HSS of the IMS operator. The idea behind is that the webRTC service provider does not assume that the webRTC user has an own IMS subscription so the webRTC provider holds a pool of IMS subscriptions that can be assigned to the webRTC IMS client on demand. The pool of IMS IDs can be provided to the WWSF in form of wildcarded IMPUs.
Binding of webRTC ID and IMS ID
a. The binding can be created at HSS, WWSF, or AAA.
b. The binding can be provided to a (network) entity, for example, HSS-> WWSF, WWSF->eP-CSCF.
c. The verification of binding can be carried at the entity which created the binding or at the entity which is provided with binding.
d. Removal of the binding inclusive the IMS deregistration once it is not needed anymore.
With verification of the above described binding, operator can perform authentication and authorization when UE WIC access IMS service with a web identity (webRTC ID).
Validity time limited authentication and authorization for sending the registration message from the WIC.
eP-CSCF assignment to UE WIC via WWSF.
Using static webRTC ID to IMS ID binding or dynamic binding to a pool of IMS IDs as well as using the webRTC ID instead of an IMS ID.
