Abstract:
Disclosed are a UE configuration method, network side device and system for proximity awareness in the present invention, which are used to achieve the function of obtaining the service information by proximity awareness between terminals in a cellular communication system. The network side device configures the service ID of each service type to be sent by the transmission UE and the temporary device ID, and the network side device configures the service ID filtering template for the receiving UE according to the service types to be received by the receiving UE, and thus the configured transmission UE and the receiving UE can obtain the service information by proximity awareness.

The access method is applied to a first wireless backhaul node and includes: determining a previous hop node of the first wireless backhaul node, the previous hop node being a home donor base station of the first wireless backhaul node or being a second wireless backhaul node; and transmitting first information to the home donor base station directly or transmitting the first information to the home donor base station via the second wireless backhaul node.
Abstract:
A method for determining a data forwarding tunnel, an AMF entity, and a base station (BS) are provided. The method includes: receiving data forwarding information of target UE forwarded by MME, and acquiring a QoS flow configured by a 5G core network for each bearer of the target UE, and mapping relationship between a bearer and a QoS flow, where the data forwarding information includes a list of bearers allocated by EPS to the target UE and an indication of a determination by a 4G BS as to whether each bearer of the target UE has data to forward; transmitting the data forwarding information, the configured QoS flow, and the mapping relationship to a target 5G BS; and receiving forwarding tunnel information of a 5G BS configured for the target UE by the target 5G BS according to the data forwarding information, the configured QoS flow, and the mapping relationship.
Abstract:
A location management method and a location management device are provided by the present disclosure. The location management method includes: storing, by a network side, location information of User Equipment (UE), when the UE transmits uplink data; or updating, by the network side, the location information of the UE, when the UE reselects another cell and issues a cell update report to an accessed base station.
Abstract:
The present disclosure provides a method for determining a D2D relay node, including steps of: measuring, by a first UE, its own running state; in the case that the first UE determines that its own running state meets a predetermined condition in accordance with a measurement result, determining the first UE as a relay node; and notifying, by the first UE, other UEs currently using a D2D link that the first UE is the relay node via a PC5 interface.
Abstract:
Disclosed are a terminal control method and device, used for implementing control on a user equipment (UE) with a proximity perception capability when a D2D communication mechanism for mutual discovery even direct communication between mobile devices is introduced to a network. The method is: an MME receiving a D2D request message of a UE that is sent by a base station, determining requested D2D characteristics according to the D2D request message, determining an acceptable D2D characteristic in the requested D2D characteristics, and sending the accepted D2D characteristic to the base station; and after receiving the accepted D2D characteristic returned by the MME, the base station determining whether to accept the D2D request of the UE, and if yes, the base station performing resource configuration and instructing the UE to perform the accepted D2D characteristic; otherwise, the base station rejecting the D2D request of the UE. Also disclosed are another terminal control method and device, and further disclosed is a terminal control system.

Abstract:
Disclosed are a group communication method, device and system. An MBMS network side method comprises: receiving a session start request message sent by a mobility management device of an MBMS network; judging whether the session start request message carries a group identifier of a communication group in which a session requested by the session start request message is located; and if the session start request message carries the group identifier, forwarding the session start request message to an access network device, so that the access network device allocates an air interface identifier to the session requested by the session start request message, thereby conducting group communication. In the embodiments of the present application, a session start message transferred by an MBMS network side carries a group identifier, thus realizing group communication based on an MBMS network.
Abstract:
Disclosed are a method, device and system for maintaining the continuity of a group communication service, for solving the problem in the prior art that the service continuity requirement of group communication may not be satisfied due to the switching of network service from multicast transmission to unicast transmission in an MBSFN domain. The method comprises: when determining that group communication service needs to be switched from multicast transmission to unicast transmission, a GCSE-AS notifies a terminal served by the GCSE-AS that the GCSE-AS is going to switch the group communication service from multicast transmission to unicast transmission; and after receiving a first notification message transmitted by the terminal, the GCSE-AS transmits the group communication service over a unicast carrier established by the terminal for unicast transmission, and stops transmitting the communication service in multicast mode. The terminal has already established a unicast carrier for unicast transmission before the GCSE-AS switches the group communication service from multicast transmission to unicast transmission, thus ensuring the continuity of the group communication service.
