A data service processing method in a roaming scenario includes: acquiring information about a roaming service provider selected by a subscriber, where the acquired information includes an identifier of the roaming service provider; selecting a gateway according to the acquired information about the roaming service provider; and performing data service processing by using the gateway. In addition, a corresponding network side device and a corresponding communications system are further provided.

Data service processing method, apparatus, and system in roaming scenario

Embodiments of the present invention relate to the field of communications, and provide a data transmission method, apparatus and system. The method includes: detecting whether data transmitted in a received GTP-U data packet is data of a predetermined type; if a result of the detection is that data transmitted in the GTP-U data packet is data of a predetermined type, decapsulating the GTP-U data packet, to obtain the data of the predetermined type and a destination address of the data of the predetermined type; and sending the data of the predetermined type and the destination address to a message gateway, so that the message gateway forwards the data of the predetermined type according to the destination address. A gateway includes: a detection module, a decapsulation module, and a sending module. A message gateway includes: a receiving module and a forwarding module.

Data transmission method, apparatus and system

Embodiments of the present application provide a method for a handover without a default bearer. A first network device sends a relocation request to a second network device. The second network device establishes a connection to a third network device indicated by the relocation request, and sends a response to the first network device and indicates that data is to be sent by using a signaling plane. Then the first network device instructs a source network device to forward the data to a target network device according to a forwarding mode indicated by a handover command. Alternatively, after the second network device establishes the connection to the third network device indicated by the relocation request, the third network device caches data, and after a handover of user equipment is completed, the third network device sends the cached data to the second network device.
