  • Patent number: 11438811
    Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configurable to operate as a source gNB (S-gNB). The S-gNB may transfer, from a control plane (CU-CP) of the S-gNB to a CU-CP of a target gNB (T-gNB), an XnAP handover request message that indicates an Xn handover of a User Equipment (UE) from the S-gNB to the T-gNB. The S-gNB may initiate data forwarding, from a user plane (CU-UP) of the S-gNB to a CU-UP of the T-gNB, of downlink data packets. The data forwarding may be terminated based on reception of end marker packets from a user plane function (UPF) entity. The CU-UP of the S-gNB may transfer end marker packets to the CU-UP of the S-gNB to indicate termination of the data forwarding.

  • Publication number: 20220078692
    Abstract: A computer system that establishes a first registration and a second registration in a common wireless communication system is described. During operation, the computer system performs a first registration of the user equipment over a first access, where, after the first registration, the user equipment is connected via the first access with a first access and mobility management function (AMF). Then, the computer system performs a second registration of the user equipment over a second access, where the second access is different from the first access and, after the second registration, the user equipment is connected via the second access with a second AMF. Moreover, when performing the second registration, the computer system: transfers a context of the user equipment from the first AMF to the second AMF; and/or relocates a network interface in a control plane from the first AMF to the second AMF.

  • Patent number: 11265884
    Abstract: Mapping information of a bearer or quality of service can be communicated from a Wireless Local Area Network Termination (WT) to the enhanced Node B (eNB), which then uses radio resource control (RRC) signaling to communicate the mapping to the user equipment (UE). For example, three options can be used to communicate mapping information: (1) Operations and Management (OAM), (2) Semi-static Xw-AP signaling (e.g., WT Configuration Update or Xw Setup procedures) or (3) Dynamic Xw-AP procedures (e.g., WT Addition Request procedure). In some embodiments, the mapping can be signaled by (1) bearer to wireless local area networks (WLAN) access category (AC) mapping or (2) long term evolution (LTE) quality of service class identifier (QCI) to WLAN AC mapping.
