One disclosure of the present specification provides a method by which a network entity, which controls a control plane, determines whether to offload traffic of a user equipment (UE) to a wireless local area network (WLAN). The method can comprise a step of acquiring subscriber information on the UE from a subscriber information server, wherein the subscriber information can include a WLAN offloadability indication for a specific packet data network (PDN) connection. The method can comprise the steps of: determining WLAN offloadability for the specific PDN connection on the basis of the WLAN offloadability indication and configuration information; transmitting the WLAN offloadability indication to network nodes according to the determination; and transmitting the WLAN offloadability indication to the UE according to the determination.

Described herein are apparatus, systems and methods for improved mobility between wireless networks. A method may comprise, at a user equipment (UE) in communication with a cellular network activating a detach timer for the cellular network, detecting a short-range network, communicating with the short-range network, storing registration and bearer context data related to the cellular network, interrupting communication with the cellular network, and prior to the expiration of the detach timer, reconnecting to the cellular network via a service request without using an attach procedure.

Applicants disclose an inter-system mobility anchor control point that is adapted to initiate handover of an existing communication connection in an integrated small cell and WiFi (ISW) network. The inter-system mobility anchor control point is communicatively coupled to both an HeNB/LTE network and trusted WLAN access network (TWAN) and adapted to operate as a common control plane entity for both HeNB/LTE and TWAN access. The mobility anchor control point may be a mobility management entity (MME) or an integrated small cell and WLAN gateway (ISW GW). The mobility anchor control point is adapted to request and receive measurement data relating to the operations of the HeNB network and WLAN. Based upon the measurement data, the mobility anchor control point determines whether an existing communication path via one of the HeNB/LTE network and WLAN should be handed over to the other of the networks.

Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) associated with a first radio access network (RAN) may identify a user equipment (UE) connected to a source base station of the first RAN. The AMF may receive a handover message including a voice call continuity handover trigger message indicating a handover of the UE to a target base station associated with a second RAN. In some examples, the AMF may transmit a bypass handover message to a second network device based a on the received handover message. In some cases, the bypass handover message may include the voice call continuity handover trigger message. In some examples, the second network device is a mobility management entity (MME) associated with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN).

A function executing device may comprise a first wireless interface according to a Bluetooth Low Energy scheme being capable of repeatedly sending an advertising signal. The function executing device may after a first advertising signal in which a first radio field intensity is used has been sent from the first wireless interface, receive a specific signal via the first wireless interface from a terminal device, change a radio field intensity used for sending the advertising signal from the first radio field intensity to a second radio field intensity lower than the first radio field intensity, and after a second advertising signal in which the second radio field intensity is used has been sent from the first wireless interface, establish a first wireless connection with the terminal device via the first wireless interface.

A device, system, and method for switching between a narrowband network and a broadband network is provided. A radio device determines conditions of a broadband network and receives, from a narrowband network site, access criteria indicating that a subset of a plurality of radio devices can register with the narrowband network site to communicate on a narrowband network. In response to the conditions meeting one or more given conditions and receiving the access criteria, when the radio device is communicating on the broadband network, the radio device may continue communicating on the broadband network; or when the radio device is communicating on the narrowband network, or attempting to register with the narrowband network site, the radio device switches, from communicating on the narrowband network, or attempting to register with the narrowband network site, to communicating on the broadband network.

Disclosed in the present application are a network switching method, a storage medium, and an electronic device. The method comprises: when a source signal strength and a target signal strength meet a preset condition, determining a communication network according to a source transmission delay and a target transmission delay; when the signal strength of a source network is poor, a target network can be switched to so as to solve the problem of poor call quality. By comparing the transmission delays of the source network and the target network, the problem of call quality worsening after switching due to the high transmission delay of the target network can be avoided.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, during an active call on a first radio access technology (RAT), that a first condition for performing a handover from the first RAT to a second RAT is satisfied. The UE may determine that the second RAT would trigger a fallback to a third RAT after the handover from the first RAT to the second RAT and that a second condition for performing a handover from the third RAT to the first RAT is satisfied. The UE may refrain from performing the handover from the first RAT to the second RAT based at least in part on the determination that the second RAT would trigger the fallback and the determination that the second condition is satisfied. Numerous other aspects are provided.

A communication method for incorporating an IoT technique with a 5G communication system for supporting a higher data transmission rate in comparison with a 4G system and subsequent systems and a system therefor are disclosed. The present invention can be applied to intelligent services (for example, services related to smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security, and safety) on the basis of a 5G communication technique and IoT-related techniques. A method for transmitting and receiving a signal in a terminal of a mobile communication system, according to one embodiment of the present specification, comprises the steps of establishing an access for a specific PDN connection with a base station and a wireless local area network (WLAN); detecting that the access through the WLAN is unusable; and transmitting, to a mobility management entity (MME), a control message for moving traffic through the WLAN, through the base station. According to one embodiment of the present specification, a traffic transmission path of the terminal capable of accessing both a 3GPP network and a non-3GPP network can be controlled in the network and the traffic transmission path can be determined according the states of the network and the terminal, thereby effectively utilizing limited communication resources.

The present invention relates to a handover method between heterogeneous wireless communication techniques and a device for same. A wireless access device is capable of: transmitting to a terminal condition information related to conditions required for the terminal to carry out a predetermined reporting action; establishing wireless connection with the terminal, when a request from the terminal due to the reporting action has been received; providing to a network controller of a core network a message according to the reporting action; receiving from the network controller context information of the terminal for establishing security and data bearers; establishing a data bearer for each data flow to be handed over by using the context information, when a request for data transmission/reception according to the handover has been received from the terminal; and receiving data from the terminal.
