DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. Before describing the embodiments of the present application, the D2D technology involved in this embodiment is described. The D2D technology generally includes a D2D discovery technology and a D2D communication technology: The D2D discovery technology is used to determine/determine two or more D2D user equipments. The techniques are mutually adjacent (eg, within a range in which D2D direct communication can be performed) or used to determine/determine that the first user equipment is adjacent to the second user equipment. The D2D user equipment can discover the other party by sending or receiving discovery signals/information. Under the coverage of the cellular network, the network can assist the D2D user equipment to perform D2D discovery; the D2D communication technology refers to some or all communication data between the D2D user equipments. A technology that communicates directly without going through a network infrastructure. The following embodiments relate to connection management of D2D communication, and therefore, regardless of how D2D discovery and D2D communication are performed, the implementation of connection management of D2D communication is not affected. In this embodiment, a device-to-device connection management method is provided. FIG. 2 is a flowchart of a device-to-device connection management method according to an embodiment of the present invention. As shown in FIG. 2, the process includes the following steps: S202, sending a message to the terminal of the device to the device D2D communication, where the message is used to indicate that the terminal that receives the message performs the management of the D2D connection; and in step S204, the response message of the two terminals of the D2D communication is received, where The response message is used to indicate that the terminal that sent the response message completes the management of the D2D connection. In step S206, the indication information is sent to both the terminals of the D2D communication, where the indication information is used to notify the completion of the management of the D2D connection.

The management of the D2D connection is set to the access network side and the terminal side (also referred to as the UE side). For the management of the normal connection, both the terminal side and the base station side to which it accesses can know how to proceed, because the terminal and the terminal belong to Base station. However, for D2D connections, it also involves communication between the terminal and the terminal, which is different from the general connection management. For example, the establishment process of the radio bearer is based on the link between the base station and the UE side, and the base station side grasps the configuration completion information of the local radio bearer, and only needs to configure the radio bearer of the UE through the protocol and obtain the radio bearer of the UE side through the response message of the UE. Configuration information. Therefore, after the existing radio bearer configuration process is successfully completed, both the base station side and the UE can consider that the other party has completed configuration and starts transmission. However, in the D2D communication, the link is established between the two terminals, and the configuration is performed by the base station and the terminal respectively, in this case, even the radio bearer flow of the base station side and the terminal side After the successful establishment is completed, the terminal side cannot determine whether the radio bearer path of the base station side and the D2D peer UE is successfully established. Therefore, the present invention provides a D2D connection establishment method to solve the above problems.

These preferred embodiments are described separately below. The following preferred embodiments may be used alone or in combination. Embodiment 1 FIG. 4 is a schematic diagram of establishing a D2D connection in which the terminal is in the coverage of the same base station according to an embodiment of the present invention. As shown in FIG. 4, the scenario is applicable to a scenario in which the terminal is in the coverage of the same base station. Step 1: The base station side determines the trigger. D2D connection between UE 1 and UE 2

The D2D connection trigger can be initiated by the terminal. For example, UE 1 finds that UE 2 is in a neighboring area and supports D2D communication, and UE 1 may actively send a message to the base station, carrying information such as the peer user ID and the D2D request type. The The message can be either a NAS message or an RRC message. In the case of a NAS message, the base station can unpack the NAS message and parse out the D2D service request therein, which requires the base station to support the gateway function and the prose server function. If it is an RRC message, the base station can directly parse it. After the parsing is completed, the base station finds the UE 2 and determines that the D2D connection can be triggered. The D2D connection trigger can be initiated by the base station by measurement. For example, the base station can configure the D2D discovery measurement for the UE 1 and the UE 2 that support the D2D connection. Both the UE 1 and the UE 2 can discover the other party and report the measurement report to the base station. The base station side can determine that the UE 1 and the P UE 2 can be triggered based on the information. D2D connection.

The D2D connection trigger can also be triggered by the core network side. For example, the UE 1 can find that the UE 2 is in the neighboring area and supports the D2D communication, and the UE 1 can actively send the NAS message to the core network side, carrying the peer ID and the D2D request type, and the core network element and the Prose server determine that the D2D communication can be performed at this time. Then, the base station is configured to trigger the D2D communication between the UE 1 and the UE 2, and the configuration message carries information such as the D2D two-end information and the D2D communication type indication. Step 2: The base station sends a radio resource configuration request message to the UE 1 and the UE 2 sends a message to the UE 1 and the UE 2 may be simultaneously transmitted. For example, after the base station determines that the UE 1 and the UE 2 establish a D2D connection, the base station sends a radio resource configuration request message to the UE 2 without waiting for the response of the UE 1 when transmitting the radio resource request message to the UE 1. Sending a message to the UE 1 and P UE 2 may be sent in order. For example, after the base station determines that the UE 1 and the UE 2 establish a D2D connection, the base station sends a radio resource configuration request message to the UE 2 after receiving the radio resource request response of the UE 1. If the UE 1 and the UE 2 are in the non-connected state, the base station needs to page the UE to perform the connection state, and then send the configuration to the UE by using a message. Step 3: The terminal responds to the radio resource configuration request message to the base station. Step 4: The base station sends a D2D connection success indication to the terminal. After the UE 1 and the UE 2 respectively return a successful response message to the base station, the base station determines that the configurations of both ends of the D2D connection are successfully performed. , D2D data services can be carried out. Then, the D2D connection success indication is sent to the terminal. The indication message may be sent by using an RRC message, and the base station configures the indication message and sends the message to the UE on the control plane connection that the two UEs have established. After the connection success indication message is received, UE 1 and UE 2 consider that the peer D2D connection has been successfully established and start transmitting data. The indication message may be sent by paging, and UE 1 and UE 2 may listen to the paging channel at this time. After determining that the D2D connection configuration is successfully completed, the base station sends a paging message to UE 1 and UE 2 respectively, where UE 1 and UE 2 are After accepting the paging message, it is considered that the peer D2D connection has been successfully established, and data transmission starts. The indication message may be sent by using a broadcast message, and the UE 1 and the UE 2 may listen to the specific broadcast information at this time. After determining that the D2D connection configuration is completed, the base station broadcasts a successful establishment indication of the service in a certain SIB, where the UE 1 and the UE 2 are After receiving a specific broadcast message, it is considered that the peer D2D connection has been successfully established and data transmission is started. The indication message may be sent by using a multicast message, and the UE 1 and the UE 2 may listen to the multicast control channel, for example, the MBMS control channel, and the base station broadcasts the D2D service establishment completion indication in the MBMS control channel after determining that the D2D connection configuration is completed. After receiving the MBMS control information, UE 1 and UE 2 consider that the peer D2D configuration has been completed and start transmitting data. The indication message may also be sent by the MAC control unit. If the UE 1 and the UE 2 are configured to the radio bearer of the base station, the base station may send a specific packet, the UE 1 and the UE, in the radio bearer after determining that the D2D connection configuration is completed. 2 After receiving a specific message, it is considered that the peer D2D configuration has been completed and data transmission is started. Embodiment 2 FIG. 5 is a schematic diagram of establishing a D2D connection in which a terminal is in a coverage of a different base station according to an embodiment of the present invention. As shown in FIG. 5, the scenario is applicable to a scenario in which the terminal is in a coverage of different base stations. Step 1: The base station side determines the trigger. D2D connection between UE 1 and UE 2

The D2D connection trigger can be initiated by the terminal. For example, UE 1 finds that UE 2 is in a neighboring area and supports D2D communication, and UE 1 can actively send a message to base station 1, and carries information such as a peer user ID and a D2D request type. The message can be either a NAS message or an RRC message. If it is a NAS message, the base station can unpack the NAS message and parse out the D2D service request. This requires the base station to support the gateway function and the prose server function. If it is an RRC message, the base station can directly parse it. After the parsing is completed, the base station 1 finds that it is under the base station 2 according to the information of the UE 2, and the base station 1 continues to forward the request message to the base station 2, carrying the UE 2 information and the D2D connection indication. The base station 2 judges that it can support D2D communication and returns a message to the base station 2 based on the information. The base station 1 and the base station 2 successively judge that the D2D connection of the UE 1 and the UE 2 can be triggered.

The D2D connection trigger can also be initiated by the base station by measurement. For example, the base station 1 can be a UE that supports the D2D connection, and the base station 2 configures the D2D discovery measurement for the UE 2 that supports the D2D. The UE 1 and the P 2 can both discover the other party and report the measurement report to the respective base station, and the base station 1 and or The base station 2 acquires the peer UE message based on this information. Interest on other base stations. The base station 1 and the base station 2 exchange information, and carry the peer UE identifier and the D2D connection type. After confirming that the D2D communication is supported, the base station 1 and the base station 2 confirm that the D2D communication can be triggered.

The D2D connection trigger can also be triggered by the core network side. For example, the UE 1 can find that the UE 2 is in the neighboring area and supports the D2D communication, and the UE 1 can actively send the NAS message to the core network side, carrying the peer ID and the D2D request type, and the core network element and the Prose server determine that the D2D communication can be performed at this time. Then, the base station 1 and the base station 2 are respectively configured to trigger the D2D communication between the UE 1 and the UE 2, and the configuration message carries information such as the D2D two-end information and the D2D communication type indication. Inter-base station communication uses the X2 interface preferentially, or uses the S1 interface. Step 2: The base station sends a radio resource configuration request message to UE 1 and UE 2 to send a message to UE 1 and UE 2 may be simultaneously transmitted. For example, base station 1 and base station 2 are respectively configured with respective

Sending a message to UE 1 and UE 2 may be sent in order. For example, the base station 1 can configure the UE 1 after the base station 2 has configured the UE 2. If the UE 1 and the UE 2 are in the non-connected state, the base station needs to page the UE to perform the connection state, and then send the configuration to the UE by using a message. Step 3: The terminal responds to the radio resource configuration request message to the base station. Step 4: The base station sends a D2D connection success indication to the terminal. After the UE 1 and the UE 2 respectively return a successful response message to the base station, after the inter-base station interaction success message: For example, the base station 1 completes After the configuration of the UE 1 is received, the successful configuration information sent by the base station 2 is sent to the base station 2, and the base station 2 confirms that the UE 2 is successfully configured and then sends the message to the base station 1. The base station of the two parties determines that the UE configuration of the two ends of the D2D connection has been successfully completed, and the D2D data service can be performed. The base station sends a D2D connection success indication to each terminal. The indication message may be sent by using an RRC message, and the base station 1 and the base station 2 configure the indication message and send to the UE on the control plane connection that the two UEs have established respectively. After the connection success indication message is received, UE 1 and UE 2 consider that the peer D2D connection has been successfully established. The indication message may be sent by paging, and UE 1 and UE 2 may listen to the paging channel of the respective base station at this time, and base station 1 and base station 2 respectively send paging messages to UE 1 and UE 2 after determining that the D2D connection configuration is successfully completed. After receiving the paging message, UE 1 and P UE 2 consider that the peer D2D connection has been successfully established. The indication message may be sent by using a broadcast message. The UE 1 and the P UE 2 may listen to the specific broadcast information of the respective base station at this time. After determining that the D2D connection configuration is completed, the base station broadcasts a successful establishment indication of the service in an SIB. After receiving the specific broadcast message, the P UE 2 considers that the peer D2D connection has been successfully established. The indication message can be sent by using a multicast message. The UE 1 and the UE 2 can listen to the multicast control channel, for example, the MBMS control channel. After determining that the D2D connection configuration is completed, the base station broadcasts the D2D service establishment in the respective MBMS control channel. It is indicated that UE 1 and UE 2 consider that the configuration of the peer D2D has been completed after receiving the MBMS control information, and starts to send data. The indication message may also be sent by the MAC control unit. If the UE 1 and the UE 2 are configured to the radio bearer of the base station, the base station may send a specific packet, the UE 1 and the UE, in the radio bearer after determining that the D2D connection configuration is completed. 2 After receiving a specific message, it is considered that the peer D2D configuration has been completed and data transmission is started. Inter-base station communication uses the X2 interface preferentially, or uses the S1 interface.

The main purpose is to modify the quality of service parameters (QoS) of the D2D connection. Step 2: The base station sends a radio resource change message to the UE 1 and the UE 2 sends a message to the UE 1 and the UE 2 may be simultaneously transmitted. For example, after the base station determines that the UE 1 and the UE 2 establish a D2D connection, the base station sends a radio resource change message directly to the UE 2 without waiting for the response of the UE 1 when transmitting the radio resource change message to the UE 1. Sending a message to UE 1 and UE 2 may be sent in order. After receiving the radio resource change response of the UE 1, the base station sends a radio resource change message to the UE 2. Step 3: The terminal responds to the radio resource change message to the base station When the terminal receives the radio resource update message, it suspends the service. After completing the update configuration, respond to the radio resource change message to the base station. Step 4: The base station sends a D2D connection success indication to the terminal. After the UE 1 and the UE 2 respectively return a successful response message to the base station, the base station determines that the configurations of both ends of the D2D connection are successfully performed, and the D2D data service can be restored. Then, the D2D update completion indication is sent to the terminal. The indication message may be sent by using an RRC message, and the base station configures the indication message and sends the message to the UE on the control plane connection that the two UEs have established. After accepting the message, UE 1 and UE 2 judge that the peer D2D connection has been successfully updated, and resume transmitting data. The indication message may be sent by paging. The UE 1 and the UE 2 may listen to the paging channel at this time. After determining that the D2D connection configuration is successfully updated, the base station sends a paging message to the UE 1 and the UE 2, respectively, and the UE 1 and the UE. 2 After accepting the paging message, it is considered that the peer D2D connection has been successfully updated, and the transmission data is resumed. The indication message may be sent by using a broadcast message, and the UE 1 and the UE 2 may listen to the specific broadcast information at this time. After determining that the D2D connection configuration is completed, the base station broadcasts a successful update indication of the service in a certain SIB, where the UE 1 and the UE 2 are After receiving the specific broadcast message, it is considered that the peer D2D connection has been successfully updated, and the data is resumed. The indication message may be sent by using a multicast message, and the UE 1 and the UE 2 may listen to the multicast control channel, for example, the MBMS control channel, and the base station broadcasts the D2D service update completion indication in the MBMS control channel after determining that the D2D connection update is completed. After receiving the MBMS control information, UE 1 and UE 2 consider that the peer D2D update has been completed and resume transmitting data. The indication message may also be sent by the MAC control unit. If the UE 1 and the UE 2 are configured to the radio bearer of the base station, the base station may send a specific packet, the UE 1 and the UE, in the radio bearer after determining that the D2D connection update is completed. 2 After receiving the specific message, it is considered that the peer D2D configuration has been completed, and the data is restored.
