the network side device is a data gateway or an access network element of the first network or an access network element of the second network.

21. The network-side device of claim 20,

if the network side device is a data gateway, the network side device further includes:

a second transmission unit, configured to, if a first uplink data packet of a first service of the user equipment is received and a source address of the first uplink data packet is the first address, convert the source address of the first uplink data packet into a third address of the network side device, and then forward the first uplink data packet whose source address is converted into the third address; if a second uplink data packet of the first service of the user equipment is received and the source address of the second uplink data packet is the second address, the source address of the second uplink data packet is converted into the third address, and then the source address is forwarded to the second uplink data packet converted into the third address.

22. The network-side device of claim 20, wherein if the network-side device is an access network element of the first network or an access network element of the second network,

the network side device further includes:

a third transmission unit, configured to convert a source address of a first uplink data packet into a second address and forward the first uplink data packet whose source address is converted into the second address if the first uplink data packet of a first service of the user equipment is received, and a source address of the first uplink data packet is the first address, and the first uplink data packet is response data of the first downlink data packet, and a destination address of the first downlink data packet is the second address;

or,

if a second uplink data packet of the first service of the user equipment is received, the source address of the second uplink data packet is the second address, the second uplink data packet is response data of the first downlink data packet, and the destination address of the first downlink data packet is the first address, converting the source address of the second uplink data packet into the first address, and forwarding the second uplink data packet of which the source address is converted into the first address.

23. A user device, comprising:

a first access unit, configured to access a first network and obtain a first address allocated to the user equipment for transmitting a service in the first network;

a second access unit, configured to access a second network and obtain a second address allocated to the user equipment for transmitting a service in the second network, where the first network and the second network are networks of different systems;

the receiver is used for receiving a first downlink data packet of the first service through the second network, or receiving a second downlink data packet of the first service through the first network, and receiving a third downlink data packet of the first service through the second network;

and the transmitter is used for transmitting the uplink data packet of the first service only through the first network.
