METHOD AND DEVICE FOR NEGOTIATING MACHINE TYPE COMMUNICATION DEVICE GROUP ALGORITHM
First Claim
1. A method for negotiating machine type communication (MTC) device group algorithms, comprising:
- selecting a negotiated group encryption algorithm from group encryption algorithms supported by an MTC device;
selecting a negotiated group integrity algorithm from group integrity algorithms supported by the MTC device; and
sending a security mode command message or a radio resource control (RRC) connection reconfiguration message to the MTC device, wherein the security mode command message or the RRC connection reconfiguration message carries the negotiated group encryption algorithm and the negotiated group integrity algorithm.

Abstract
Disclosed is a method for negotiating machine type communication (MTC) device group algorithms, including: selecting a negotiated group encryption algorithm and a negotiated group integrity algorithm from group encryption algorithms and group integrity algorithms supported by an MTC device; sending a security mode command message or a radio resource control (RRC) connection reconfiguration message to the MTC device, wherein the security mode command message or the RRC connection reconfiguration message carries the negotiated group encryption algorithm and the negotiated group integrity algorithm. The method disclosed in this invention enables the MTC devices to realize the encryption and the integrity protection of communication contents when performing group communication.
