Circuit switched fallback
Technology for facilitating circuit switched fallback (CSFB) for a user equipment (UE) is disclosed. A mobility management entity (MME) can receive an optimized CSFB capability indicator from the UE. The MME can receive a requested service type associated with the UE. The MME can initiate a single radio voice call continuity (SR-VCC) handover of the UE to a circuit switched network based on the optimized CSFB capability of the UE. The MME can send an S1 application protocol (S1-AP) request message to an evolved node B (eNB). The S1AP message can include the optimized CSFB capability indicator and a single radio voice call continuity (SRVCC) indicator for the UE. The MME can receive a handover required message from the eNB.
DYNAMIC RADIO COVERAGE AREA TRANSITION MANAGEMENT
A coverage transition is performed where a compensation service area is expanded to cover an energy saving service area and the energy saving service area is deactivated. The coverage transition is managed by transferring user equipment devices (UE devices) from an energy saving service area to a transition service area that at least partially overlaps with the energy saving service area. The UE devices may be transferred using a handover procedure between communication stations where each UE device is assigned communication frequencies for communication with the transition communication station that are not used by the energy saving communication station or the compensation service area, thereby avoiding, or at least minimizing, interference. After all UE devices are transferred from the energy saving service area, the communication stations are configured to deactivate the energy saving service area and to expand the compensation service area to cover the energy saving service area.
COMMUNICATION METHOD, NETWORK DEVICE, AND TERMINAL DEVICE
A network device communicates with a first terminal device by using a first communication link, the first terminal device communicates with at least one second terminal device by using at least one second communication link the network device receives a measurement report sent by the first terminal device, where the measurement report includes at least one piece of measurement data; and sends to the first terminal device, indication information of a communication link change policy determined based on the at least one piece of measurement data, where the indication information is used to instruct the first terminal device to perform change processing on a communication link based on the communication link change policy, where the communication link includes at least one of the first communication link or the second communication link.
INTER-SMALL CELL HANDOVER METHOD, DEVICE, AND SYSTEM
The present application relates to the field of communications technologies, and provides an inter-small cell handover method, a device, and a system. When UE is in a coverage hole of a serving small cell, the UE needs to perform synchronous measurement only on each available beam pair in a set of available small cells determined by the UE, thereby reducing a delay of re-accessing a high frequency network by the UE, and improving QoS of receiving a high frequency service by the UE. the present application includes: performing, by UE, synchronous measurement, to determine a set of small cells available for the UE; sending the set of available small cells to a macro base station; when the UE is in a coverage hole of a current serving small cell, receiving, by the UE, a first synchronization indication sent by the macro base station.
