Abstract: Embodiments of the present invention provide a wireless local area network WLAN measurement and reporting method, and a related device. The method includes: acquiring, by a user terminal, WLAN group information, where the WLAN group information indicates at least one WLAN group; determining, by the user terminal, whether at least one WLAN in the WLAN group satisfies WLAN measurement configuration information; and reporting, by the user terminal, a measurement result of the at least one WLAN in the WLAN group to a base station when the at least one WLAN in the WLAN group satisfies the WLAN measurement configuration information. Therefore, a signaling resource can be saved, thereby reducing signaling load caused by simultaneous reporting of a large quantity of WLAN measurement results.

Abstract: This application provides a network access method, an access device, and a terminal device. The access device is connected to at least two different types of core networks. When the terminal device is to connect to a core network, the terminal device sends, to the access device, a first message used to indicate a type of the terminal device. The access device determines the type of the terminal device based on the first message, and determines, based on the type of the terminal device, a target core network to be connected by the terminal device, so that the access device accurately connects the terminal device to the target core network.

Abstract: A method, apparatus and system for establishing S1 signaling connections in an evolved network are disclosed. A source evolved NodeB (eNodeB) sends a handover request message to a target eNodeB to initiate a handover procedure during that a user equipment (UE) is handed over from the source eNodeB to the target eNodeB. The handover request message includes information about an original S1 signaling connection parameter. When the UE enters the target cell, the target eNodeB allocates a new S1 signaling connection parameter and sends a handover complete message to an evolved packet core (EPC). The handover complete messages carries the original S1 signaling connection parameter received from the source eNodeB and the allocated new S1 signaling connection parameter about the target eNodeB. With the present disclosure, the inability of the target eNodeB to establish an S1 signaling connection with the EPC in the related art is effectively solved.

Abstract: A method and an apparatus for non-access stratum (NAS) message processing during handover in an evolved network are provided. The method includes the following steps. An evolved packet core (EPC) receives a message which indicates that a UE is being handed over sent by a source evolved NodeB (S-eNB), and stops sending an NAS message to the UE temporarily. The EPC receives a message which indicates that the UE returns to an S-eNB service area sent by the S-eNB. The EPC sends the NAS message to the UE through the S-eNB, if needed. With the method and the apparatus, the EPC can acquire a location of the UE in time in the case of a handover failure of the UE, a time limit of a retransmission timer is set precisely, and a specific implementation for forwarding an NAS message through an X2 interface is provided.

Abstract: A method, an apparatus, and a system for collecting information about a wireless local area network (WLAN) access point (AP). The method specifically includes: a user equipment (UE) receives WLAN AP request information from a base station in a Minimization of Drive Tests (MDT) measurement configuration process, collects WLAN AP information according to the WLAN AP request information, and sends the WLAN AP information to the base station, wherein the WLAN AP request information is used to request the UE to report WLAN AP information. By using an MDT measurement configuration process, a UE may collect and report WLAN AP information based on architecture of a mobile communications network. In this way, WLAN AP information can be conveniently collected.
