The embodiment of the invention provides a kind of technical solutions of data processing, set applied to including wireless cellular network routing Standby, core network gateway and TCP(Transmission Control Protocol, transmission control protocol) agency system. In the technical scheme, wireless cellular network routing device is currently eated dishes without rice or wine carrying into the upstream data packet that core network gateway is sent Channel state parameter；Core network gateway receive the carrying currently eat dishes without rice or wine channel state parameter upstream data packet after, will be on this The channel state parameter of currently eating dishes without rice or wine carried in row data packet is transmitted to TCP agent；TCP agent receives the letter of currently eating dishes without rice or wine After road state parameter, channel state parameter of currently being eated dishes without rice or wine according to this carries out transmission optimization, is guaranteeing to eat dishes without rice or wine in channel state parameter While reporting accuracy, the real-time that channel state parameter of eating dishes without rice or wine reports is improved.
Wherein, in embodiments of the present invention, the upstream data packet that wireless cellular network routing device is sent to core network gateway Middle carrying currently eat dishes without rice or wine channel state parameter can carry the initial IP protocol header in upstream data packet, raw tcp protocol head, Or GTP-U(GPRS(General Packet Radio Service, General Packet Radio Service) Tunneling Protocol For the user plane, the GPRS Tunnel Protocol of user level) in protocol header, these three situations are retouched separately below It states.
What situation one, wireless cellular network routing device were carried into the upstream data packet that core network gateway is sent currently eats dishes without rice or wine Channel state parameter carries in the initial IP protocol header of upstream data packet:
IP agreement is the agreement in network layer, it mainly completes the transmission effect of data packet；
The data pack protocol head format of IPv4 can be as shown in Figure 1A, wherein the last one field of the protocol header is optional Extension (Option Field).The Option Field is using 32 bits as boundary, the byte of padding that inserted value is 0 when necessary, thus Guarantee that IP stem is the integral multiple of 32 bits always.
Option Field format specification is as follows in each IP agreement head: the option type (code field) of a byte, and one The option byte length of byte identifies (len field), and remainder is the relevant privately owned definition field of option type.
In embodiments of the present invention, wireless cellular network routing device is in the upstream data packet addition sent to user terminal Before GTP-U tunnel encapsulation, can in the initial IP protocol header of the upstream data packet in a manner of Extended Protocol Option Field, The corresponding channel state parameter of eating dishes without rice or wine of the user terminal is carried in the initial IP protocol header.Complete GTP-U tunnel encapsulation it Afterwards, wireless cellular network routing device can send the upstream data packet for carrying current channel condition parameter to core network gateway.
In such a case it is possible to be parsed by core network gateway and obtained working as of carrying in upstream data packet initial IP protocol header Before eat dishes without rice or wine channel state parameter, working as of carrying in upstream data packet initial IP protocol header can also be parsed and obtained by TCP agent Before eat dishes without rice or wine channel state parameter；
Correspondingly, it currently eats dishes without rice or wine channel status in the carrying that core network gateway receives the transmission of wireless cellular network routing device After the uplink data messages of parameter, specific processing be can be such that
Core network gateway obtains the channel status ginseng of currently eating dishes without rice or wine carried in the initial IP protocol header of the upstream data packet Number, and channel state parameter that this currently is eated dishes without rice or wine is transmitted to TCP agent, channel status of currently being eated dishes without rice or wine by TCP agent according to this are joined Number carries out transmission optimization；Or,
