    • 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.
    • 公开了用于在不同的无线电接入技术(RAT)上执行多个注册的系统,方法和计算机程序产品。 在一个方面,注册过程规定移动设备向主RAT注册,并且使用其与主RAT不同的空中接口对至少一个非主RAT进行预注册。 预注册过程包括与非主要RAT建立无线电会话上下文和分组数据网络(PDN)上下文。 该过程进一步包括设置与外部PDN网关的伪绑定,并从PDN网关获取移动设备的绑定状态信息,而不将绑定状态从主RAT转移到非主RAT。 可以将绑定状态信息添加到PDN上下文。 然后,移动设备可以使用预设上下文来执行从主RAN到非主RAN的切换。
