摘要： A wireless access node (110) serves wireless User Equipment (UEs) (101 – 103) and wireless Integrated Access and Backhaul Mobile Terminations (IAB MTs) (141, 142). A radio (111) exchanges access communications with the UEs (101) over a frequency channel. The radio (111) receives an IAB request from one of the IAB MTs (141), and in response, a controller (121) allocates the frequency channel into a UE subchannel and an MT subchannel. The radio (111) now exchanges access communications with the UEs (101) over the UE subchannel and exchanges backhaul communications with the wireless IAB MT (141) over the MT subchannel. The controller (121) reallocates the frequency channel when an IAB MT (142) is added to give the new IAB MT (142) its own MT subchannel. The controller (121) reallocates the frequency channel when an IAB MT (142) is removed to increase the size of the UE subchannel.

摘要： A source Centralized Unit (CU) serves User Equipment (UE) (101) based on UE application context for a low-latency application in the UE (101). In the source CU, a source Application Server (AS) (115) uses a source User Plane Function (UPF) (113) to serve the low-latency application in the UE (101). In response to a handover to a target CU, the source CU indicates the source UPF (113) to the target CU. The target AS (116) in the target CU uses the source UPF ID to retrieve the UE application context for the UE (101) from the source AS (115). In the target CU, a target AS (116) serves the low-latency application based on the retrieved UE (101) application context.

摘要： A wireless communication system (100) delivers a wireless data service to User Equipment (UE) (101) responsive to a handover. A Centralized Unit (CU) (114) transfers a handover registration to a Network Repository Function (NRF) (123). A Session Management Function (SMF) (122) transfers a handover subscription for the UE (101) to the NRF (123). The CU (114) detects a handover of the UE (101) and responsively transfers a handover notice for the UE (101) to the NRF (123). In response to the handover subscription for the UE (101) from the SMF (122), the NRF (123) transfers the handover notice for the UE (101) to the SMF (122). The SMF (122) modifies the wireless data service for the UE (101) responsive to the handover notice for the UE (101). For example, the SMF (122) may implement data encryption for the UE (101) responsive to the handover.

摘要： User circuitry (102) within a wireless User Equipment ("UE") (101) that may utilize multiple subscriber identity module ("SIM") profiles activates two or more SIM profiles to be active simultaneously. The user circuitry (102) transfers service requests for wireless data services using the SIM profiles to network circuitry (103). The wireless data services may have different slice service types over different operating frequency bands of different target cells. The network circuitry (103) wirelessly exchanges data with wireless access nodes (111, 112) associated with the target cells over the operating frequency bands to establish packet data unit sessions comprising the slice service types using the respective SIM profiles such that multiple packet data unit sessions are active using multiple SIM profiles simultaneously. Various applications may be mapped to the appropriate SIM profile and packet data unit session based on the respective provisioned slice characteristics matching the respective application requirements.

摘要： A wireless communication network (100) serves a User Equipment (UE) (101) over a Radio Access Network (RAN) (111) and externally exposes RAN data. A RAN controller (112) comprises at least one of a near-Real Time RAN Intelligent Controller (near-RT RIC) (121) and a non-Real Time RAN Intelligent Controller (non-RT RIC) (122). The RAN controller (112) controls the RAN (111), and the RAN (111) responsively serves the UE (101). The RAN controller (112) identifies RAN data that characterizes the RAN service to the UE (101). The RAN controller (112) transfer the RAN data to a Network Exposure Function (NEF) (114). The NEF (114) receives the RAN data from the RAN controller (112) and exposes the RAN data to an external data system like an Application Server (AS).

摘要： User circuitry (102) within a wireless User Equipment ("UE") (101) in need of a network slice (121 - 123) or a handoff between cells identifies a slice service type. The user circuitry (102) processes an uplink interference threshold of a target cell based on the slice service type. The user circuitry (102) identifies a preferred operating frequency band (F1, F2) based on the slice service type and the uplink interference threshold of the target cell. The user circuitry (102) transfers a service request for a wireless data service having the slice service type over the preferred operating frequency band (F1, F2) to network circuitry (103). The network circuitry (103) wirelessly exchanges data with a wireless access node (111 - 113) associated with the target cell over the preferred operating frequency band (F1, F3) to establish a packet data unit session comprising the slice service type.
