Power, judges whether the UE possesses data compression capability；
Here, during practical application, step 303 can also be first carried out and perform step 302 again, i.e., described base station
After receiving the ability parameter that UE is reported, the first ability reported according to the UE, judge whether the UE has
Standby data compression capability, after obtaining judged result, then the data that the UE is sent are received, then basis is sentenced
Disconnected result decides whether that the data to reception decompress, and possesses number when judged result characterizes the UE
During according to compressed capability, the base station decompresses to the data of reception, that is, performs step 304.
Step 304：When judged result, which characterizes the UE, possesses data compression capability, the base station is to receiving

Function (step 402)；When detecting that UE supports data compression function, base station receives the number of UE transmissions
After bag, the UE packets sent are decompressed, relay to core net (step 403) afterwards；
When detecting that UE does not support data compression function, after base station receives the packet of UE transmissions, not to UE
The packet of transmission is decompressed, and is directly forwarded to core net (step 404).
Uplink data transmission method provided in an embodiment of the present invention, UE report the ability parameter of itself to base station；
The ability parameter reported can indicate that the UE possesses data compression capability；The UE is possessed based on itself
Compressed capability, data to be sent are compressed；And the data after compression are sent to the base station；Institute
State base station and receive the data that the UE is sent；The ability that the base station reports according to the UE, judge institute
State whether UE possesses data compression capability；When judged result, which characterizes the UE, possesses data compression capability,
The base station decompresses to the data of reception；The base station sends the data after decompression to core net,
Because UE has carried out compression processing to packet before data are sent, eat dishes without rice or wine to pass in this way, can efficiently reduce
The size of transmission of data bag, so as to effectively improve up covering, that is, cell edge coverage is improved,
This ensures that UE exhales success rate in rising for weak overlay area, so as to meet user speech and data service
Use demand, lifted Consumer's Experience.
