DETECTING LOSS OF IP CONTINUITY WHEN TRANSITIONING BETWEEN DIFFERENT NETWORKS |
摘要 |
<p>Aspects of the present disclosure provide techniques for preventing loss of IP continuity when transitioning between networks. Certain aspects provide methods that generally include initiating a first timer upon attempting to transition from a first RAT network to a second RAT network during an IP session and initiating a second timer if a channel in the second RAT network is successfully acquired. According to aspects, a device may transfer context of the IP session to the second RAT network if a session is successfully negotiated in the second network prior to expiration of the second timer and the first and second networks share a common core network for IP services.</p> |
