  • Patent number: 11570616
    Abstract: Methods and apparatus are provided for providing UE EPS capability information and receiving non-access stratum (NAS) security algorithm information for an interworking procedure in the 5GS network. In one novel aspect, the UE provides the UE EPS capability information in cleartext before the security mode procedure, and the NAS security algorithm information is included in a security mode command message during the security mode procedure. In one embodiment, the UE EPS capability information is an S1 mode indicator or the 5GMM capability information including the Si mode indicator. In another novel aspect, the network provides the NAS security algorithm information before interworking procedure from 5GS to LTE. In one embodiment, the network provides the NAS security algorithm information in the Registration Accept message. In another embodiment, the network provides the NAS security algorithm information in handover procedure from the 5GS to LTE.

  • Patent number: 8707321
    Abstract: A resource sharing system for a plurality of user devices accessing at least one resource at the same time is provided. The system comprises a plurality of virtual machines and a connection broker. The virtual machines are established on at least one computer, wherein each user device corresponds to at least one of the virtual machines and each of the at least one resource corresponds to one of the virtual machines. The connection broker connects to the virtual machines and receives login information from each of the virtual machines and joins the virtual machines sending the login information into a group. Through the connection broker, the user devices share and access the resources corresponding to the virtual machines in the group.
