Abstract:
A method includes initiating, by a base station, a local routing service start notification. The local routing service start notification is used for notifying a terminal apparatus that a local routing service is to be started. The method also includes receiving, by the base station apparatus, a local routing service request message sent by the terminal apparatus. The method further includes determining, according to the local routing service request message, that the terminal apparatus supports the local routing service. An IP address is assigned to the terminal apparatus, and a first assignment message is sent to the terminal apparatus. The first assignment message includes the IP address assigned to the terminal apparatus.
Abstract:
A data transmission method and a data transmission entity are disclosed. Embodiments include receiving, by a first MTC-IWF entity, first control plane signaling from a first mobility management entity, where the first control plane signaling carries a data packet that is from first UE, and wherein a target UE of the data packet is a second UE, determining, first route information, where the first route information is used for indicating a second network side device that serves second UE and sending, by the first MTC-IWF entity to the second network side device according to the first route information, second control plane signaling carrying the data packet so that the second network side device sends the data packet to the second UE.
Abstract:
The present invention provides a method for transmitting a small data packet, and a device. The method includes: receiving, by a data transmission device, small data packet indication information sent by a gateway; and if the data transmission device determines, according to the small data packet indication information, that a to-be-sent data packet is a small data packet, transmitting, by the data transmission device, the small data packet in a control plane transmission manner. The present invention can ensure that a data transmission device accurately determines a small data packet, and avoid a network signaling increase caused by a determining error, thereby reducing a network load.
Abstract:
An access control method includes: obtaining, by a protocol-stack upper layer of a terminal, an override identifier; starting, by the protocol-stack upper layer of the terminal, an application specific congestion control for data connectivity ACDC check according to a service initiated by the terminal; and, if the protocol-stack upper layer of the terminal confirms that the service initiated by the terminal can pass the ACDC check and determines that the override identifier corresponding to an application identifier of the service passing the ACDC check is overriding an access class barring ACB check, sending, by the protocol-stack upper layer of the terminal, an RRC establishment request message to an access layer of the terminal, where the request message carries an indication of not performing an ACB check. Therefore, even if the terminal cannot pass the ACB check, the terminal can still perform services of some particular applications.
Abstract:
The present invention provides a proximity information registration method, a query method, and a user equipment. The proximity information registration method includes: sending, by a first user equipment, a proximity service request to a proximity service server, where the proximity service request sent by the first user equipment carries an equipment identifier of the first user equipment; monitoring and obtaining, by the first user equipment, broadcast information of a second user equipment which is broadcast by the second user equipment; and registering the broadcast information of the second user equipment with the proximity service server, so that the proximity service server converts the broadcast information of the second user equipment into an equipment identifier of the second user equipment according to a correspondence between the equipment identifier of the second user equipment and the broadcast information of the second user equipment stored by the proximity service server.
Abstract:
The present invention discloses a device discovery method which relates to the field of communications technologies, and can reduce signaling interaction in a process of discovering a nearby device and lower power consumption of the UE. The method in the present invention mainly includes: receiving, by a server, a discovery request, where the discovery request is used to request to discover another UE near a user equipment UE, and the discovery request includes a discovery category indication; generating discovery configuration information according to the discovery category indication, and sending the discovery configuration information to a base station or the UE, where the discovery configuration information is used to configure a parameter that is used when the base station or the UE detects another nearby UE; and receiving a discovery result sent by the base station or the UE.
Abstract:
The present invention provides a bearer establishment method, a base station, a packet data gateway, and a computer system, where the bearer establishment method includes: receiving a D2D mode indication requested by an AF entity or a proximity service server for a source UE, where the D2D mode indication includes a first D2D connection establishment mode or a second D2D connection establishment mode; and according to the D2D mode indication, when a D2D connection can be established successfully, establishing the D2D connection for the source UE; or when a D2D connection cannot be established successfully, establishing a common connection if the D2D mode indication is the first D2D connection establishment mode, and feeding back a connection establishment failure response to the AF entity or the proximity service server if the D2D mode indication is the second D2D connection establishment mode.
Abstract:
Embodiments of the present invention provide an MTC device communication method, device, and system. A second network element receives, a query message sent by a first network element after the first network element identifies that a type of a received short message is a preset-type short message. The query message comprises an identifier of a receiver of the short message and an identifier of a sender of the short message. The second network element checks whether the sender is authorized to send the preset-type short message to the receiver. The second network element sends a message to the first network element indicating whether or not to send the short message to the receiver.
Abstract:
A device discovery method includes: enabling, by a first device, a device-to-device monitoring and broadcasting function; after the first device detects broadcast information of a second device, reporting the broadcast information of the second device and a user identifier of a target user to a network side, requesting that the network side obtains, according to the broadcast information of the second device, an identifier of a user that logs in to the second device, and determines whether the identifier of the user that logs in to the second device is the user identifier of the target user; and receiving a result of the determining returned by the network side, and confirming, by the first device according to the result of the determining, whether a device to which the target user logs in falls within a preset distance from the first device.
