Evolution-data optimized (EVDO) session handling during mobility with support for S101 signaling interface

摘要

Certain aspects of the present disclosure propose techniques for Evolution-Data Optimized (EVDO) session handling during inter radio access technology (IRAT) mobility with support for S101 signaling interface. A UE may determine a mobility scenario for transfer of the UE among a first cell and a second cell, while the UE has an EVDO session. The UE may further determine whether pre-registration of a UE EVDO session is allowed via an S101 signaling interface. The UE may perform a procedure related to the EVDO session based on the determined mobility scenario and whether the pre-registration is allowed or not.

1. A method for wireless communications, comprising:
determining, while a user equipment (UE) has an Evolution-Data Optimized (EVDO) session, a mobility scenario for transfer of the UE among a first cell and a second cell, wherein the first and the second cells are associated with a same radio access technology (RAT), and wherein determining the mobility scenario comprises:
determining that the transfer of the UE has taken place between the first cell and the second cell;determining whether pre-registration of a UE EVDO session via an S101 signaling interface is allowed; andperforming a procedure related to the EVDO session based on the determined mobility scenario and whether the pre-registration is allowed or not, wherein performing the procedure related to the EVDO session based on the mobility scenario comprises:when the UE transfers from the first cell to the second cell, restoring a data optimized (DO) session.
