A wireless communication device and a wireless communication method capable of curbing occurrence of latency even when performing wireless communication at predetermined time intervals are provided. MIDI data is transmitted and received by communication (B) performed through a wireless module during an intermission between communications (A) performed at predetermined time intervals through the wireless module. Accordingly, a communication speed for wireless communication is improved. Therefore, compared to a case in which wireless communication is performed by only the communication (A), MIDI data can be quickly transmitted and received, and thus occurrence of latency can be curbed.

Examples pertaining to user equipment (UE) reachability after notification in mobile communications are described. An apparatus (e.g., UE) receives an indication to initiate a notification procedure from a network over a non-3.sup.rd Generation Partnership Project (non-3GPP) access while a 3GPP access with the network is unavailable. In response, the apparatus transmits a notification response message to the network. After the 3GPP access with the network becomes available, the apparatus indicates to the network that the apparatus is reachable over the 3GPP access.

A communication method and a related device are disclosed. An evolved NodeB eNB receives a first message sent by a terminal device, where the first message is for requesting to access the eNB. The eNB sends a second message to the terminal device, where the second message includes a system message corresponding to at least one serving cell of a gNB, and the second message indicates the terminal device to be redirected to one of the at least one serving cell of the gNB, or the second message indicates the terminal device to be handed over to one of the at least one serving cell of the gNB. The terminal device receives the system message of the serving cell of the gNB from the eNB, to access the gNB.

A communication apparatus extracts a wireless network identifier from a received notification signal; based on the extracted wireless network identifier, confirms whether or not there is present a second communication operator, among communication operators other than a first communication operator of a wireless network currently being used, that is currently usable and satisfies a predetermined condition; and in the case where its presence is confirmed, makes a request for a communication profile to a subscription management apparatus that manages a communication profile for the second communication operator.

A method is disclosed for improved tracking area planning and handling, comprising: assigning a single tracking area code to a plurality of eNodeBs at a messaging concentrator gateway, the messaging concentrator gateway situated in a network between the plurality of eNodeBs and the core network; storing, at the messaging concentrator gateway, at least one indicator of a last known location of a user equipment (UE) other than the single tracking area code; receiving a paging message from the core network at the messaging concentrator gateway for a UE; and performing a paging sequence using the at least one indicator to identify a set of eNodeBs to page the UE, thereby allowing larger tracking area list sizes to be used without increasing signaling traffic between the radio access network and the core network.

A method in a radio access network, RAN, node for paging user equipment in an area spanning across a plurality of radio access technologies, RATs, comprises determining the capabilities of a user equipment to which a paging message is intended, and transmitting the paging message to the UE via one or more RATs which the UE is determined as being capable of communicating with.

Certain aspects of the present disclosure provide techniques for a UE with multiple universal subscription identity modules (i.e., a multi-USIM device) or concurrent radio access technology (C-RAT) capabilities to receive and respond to a page from a network of a first USIM of the UE while not activating a receiver on that network by receiving the page (from the network of the first USIM) on a receiver active on a network of a second USIM. A method that may be performed by a user equipment (UE) includes sending a request to register for paging events in a registration request message to an access and management function (AMF) of a network of a first universal subscriber identifier module (USIM) of the UE; sending a paging public user identifier (PPUID) of the UE, in a protocol data unit (PDU) session, to a paging server via a network of a second USIM of the UE, wherein the paging server is associated with the network of the first USIM; and receiving a message associated with the first USIM via the PDU session or another

A terminal supporting dual receive single transmit-dual subscriber identity module (SIM) dual standby (DR-DSDS) includes a first SIM card interface and a second SIM card interface. The first SIM card interface is configured to communicate with a first SIM card, and the second SIM card interface is configured to communicate with a second SIM card. The terminal is configured to, when the terminal is in a first communication connection, receive a paging request for establishing a second communication connection, and when the paging request carries a first identifier indicating a second service, respond to the paging request to establish the second communication connection.
