摘要

A radio communication terminal device may include: a cellular wide area radio communication technology circuit configured to provide a communication according to a cellular wide area radio communication technology; a circuit configured to provide a direct communication device to communication device communication; and a message generator configured to generate a message comprising information of a direct communication device to communication device communication provided by the circuit.

主权项

1. A radio communication terminal device, comprising:
a cellular wide area radio communication technology circuit to provide a communication according to a cellular wide area radio communication technology; a device-to-device (D2D) communication technology circuit to provide a direct communication device to communication device communication; and a message generator to generate a message to include information to indicate that a radio resource control (RRC) connection that is to be established based on the message is related to a direct communication device to communication device communication of the D2D communication technology circuit and to cause the cellular wide area radio communication technology circuit to transmit the message to an eNB, wherein the message is an RRC connection request message or a random access request message, wherein the message is an RRC connection request message to request to establish a mobile radio communication connection with the eNB and the message comprises a message field including information of at least one of plural reasons for the request to establish the mobile radio communication connection, wherein at least one of the plural reasons includes to provide information about an ongoing direct communication device to communication device communication of the radio communication terminal device and at least a second one of the plural reasons provides information indicating a precedence for handling of the RRC connection request message by the eNB relative to one or more other RRC connection request messages relating to D2D communication.
