METHOD AND APPARATUS FOR AVOIDING CALL DROPS DURING SERVING RADIO NETWORK SUBSYSTEM (SRNS) RELOCATION PROCEDURE |
摘要 |
A method and apparatus for avoiding call drops during Serving Radio Network Subsystem (SRNS) relocation procedure are described. In an aspect, the method may include receiving an SRNS RELOCATION message and initiating a handover procedure from a first radio network subsystem (RNS) to a second RNS based on the SRNS RELOCATION message. The method may include identifying a downlink (DL) message and identifying an uplink (UL) message. The method may include holding the DL message and the UL message at a radio resource control (RRC) layer until completion of the handover procedure. In another aspect, the SRNS RELOCATION message may include a new FRESH value. The method may include retaining an old FRESH value determined before the SRNS RELOCATION was received. The method may include applying both the old FRESH value and new FRESH value to the DL message to determine if the DL message is valid. |

1. A method for wireless communication, comprising:
receiving a Serving Radio Network Subsystem (SRNS) RELOCATION message; initiating a handover procedure from a first radio network subsystem (RNS) to a second RNS based on the SRNS RELOCATION message; identifying a downlink (DL) message; identifying an uplink (UL) message; and holding the DL message and the UL message at a radio resource control (RRC) layer until completion of the handover procedure. |
