System and methods for performing multiple registrations across different radio access technologies |
摘要 |
Disclosed are systems, methods and computer program products for performing multiple registrations across different radio access technologies (RATs). In one aspect, the registration procedure provisions a mobile device to register with a primary RAT and pre-register with at least one non-primary RAT using its air interface, which is different from the primary RAT. The pre-registration procedure includes setting up a radio session context and a packet data network (PDN) context with the non-primary RAT. The procedure further includes setting up a pseudo-binding with an external PDN gateway and obtaining binding state information for the mobile device from the PDN gateway without transferring binding state from the primary RAT to the non-primary RAT. The binding state information may be added to the PDN context. The mobile device may then perform handoff from the primary RAN to non-primary RAN using the preset contexts.
