A method for creating a Multipoint-to-Point EPS bearer in a packet switched transmission network is envisaged. A plurality of user equipments are installed within a tracking area assigned to a serving gateway. The user equipments are communicably coupled to an eNodeB, which is configured to receive the uplink data packets transmitted from the user Equipments. The eNodeB is communicably coupled to an S1 bearer, and with the S1 bearer designated as the destination for every uplink data packet transmitted from the eNodeB, the need for packet inspection at the eNodeB is eliminated. Likewise, since the S1 bearer is the only possible intermediate destination for the downlink data packets originating from the serving gateway, the process of packet inspection is also absolved at the serving gateway. The Multipoint-to-Point EPS bearer is communicably coupled to the user equipments for transmission of both uplink data packets and downlink data packets without packet inspection.

The present disclosure relates to an information recording method. The method is applicable to user equipment, and includes: receiving indication information from a base station, wherein the indication information includes mode indication information indicating a mode for recording Minimized Driving Test (MDT) information; and when the user equipment is in an inactive state, recording the MDT information according to the mode indication information. According to examples of the present disclosure, the user equipment may record the MDT information when it is in the inactive state, such that the user equipment transmits the MDT information recorded in the inactive state to the base station when the user equipment establishes or restores a communication connection with the base station later. Thus, the base station can determine various failures of the user equipment in the inactive state, thereby facilitating the base station to perform troubleshooting accurately.

A wireless communications system includes a plurality of infrastructure equipment forming part of a radio access network of a wireless communications network, and a communications device configured to transmit signals via the wireless access interface to one or more of the infrastructure equipment and to receive signals transmitted from one or more of the infrastructure equipment via the wireless access interface. The communications device is configured, when in an inactive state, to receive, from one of the infrastructure equipment, information from which an indication of one or more of the infrastructure equipment representing a notification area of the radio access network can be derived, the one or more infrastructure equipment of the notification area being for use in transmitting tether signals to the communications device from the wireless communications network.

A downlink data notification message sending method and apparatus are disclosed. In an embodiment a method includes receiving, a delay instruction from a mobility management network element, which is used to instruct a control plane network element to delay sending a DDN message, receiving, an event report message includes a reported event from a user plane network element, and the reported event is used to notify the control plane network element that a downlink data packet sent to UE matches no bearer, determining, that the UE is registered in the mobility management network element, and if the control plane network element has not received, within a first time period, routing information of a base station, sending, the DDN message to the mobility management network element when the first time period expires.

A first base station receives an uplink signal from a wireless device. The first base station receives a packet for the wireless device: after a duration from receiving the uplink signal; and when the wireless device is in a radio resource control inactive state. A determination is made that the duration is larger than a value. Based on the determining, the first base station sends a radio access network (RAN) paging to a second base station of a RAN notification area of the wireless device. The first base station sends the packet.

Disclosed are a method whereby a base station manages a UE context in a wireless communication system, and a device for supporting same. The method comprises the steps of: receiving paging-related information of UE from a core network node; storing the paging-related information; and carrying out paging with respect to the UE on the basis of the paging-related information after the UE has entered an RRC-inactive state.
