Firstly, it is necessary to illustrate, the communication equipment for a certain wireless communication technique mentioned in following files can be Any network side equipment passed through during carrying out data packet communication between transmitting terminal and receiving terminal.

The embodiment of the present invention one

A kind of data pack transmission method is provided, it is (wireless with two kinds to be mainly used for various wireless communication technology as shown in Figure 1 For the communication technology) transmission for data packet in network system under fusion, in the network system, communication terminal can lead to Any wireless communication technique transmission packet is crossed, and is connect in the presence of what is be in communication with each other between the communication equipment of two wireless communication techniques Mouthful.Such as first wireless communication technique communication equipment can be following any standard base station：LTE standards, UMTS standards and GSM standards etc., and the communication equipment of the second wireless communication technique can be the wireless access point (Access in wlan network Point, AP)；Or, the communication equipment of the first wireless communication technique can be the wireless aps in wlan network, and the second channel radio The communication equipment of letter technology is the base station of following any standard：LTE standards, UMTS standards and GSM standards etc..In base station and wirelessly There is the interface being in communication with each other between AP.Wherein wireless aps can be the terminal device as wireless communication hot spot.

The method of the present embodiment is when wireless using first between communication terminal (including following transmitting terminal and receiving terminal) During communication technology transmission packet, when communication equipment of the data packet Jing Guo the first wireless communication technique, by the first nothing Method performed by the communication equipment of line communication technology, flow is as shown in Fig. 2, include：

Step 100, the first data packet that transmitting terminal is sent is received.

Step 101, determine whether the transmission of the first data packet received for step 100 meets preset strategy, if It is to execute step 102, if it is not, then executing step 103.

Here preset strategy may include but be not limited to following any one or more information：Pass through the first channel radio The error of transmission of the first data packet of letter technology pair, in this case, when the communication equipment of the first wireless communication technique receives hair After the first data packet that sending end is sent, which is transferred to receiving terminal by the first wireless communication technique, if not The confirmation message for receiving receiving terminal return, then to the error of transmission of the first data packet；The communication of first wireless communication technique The load of equipment is more than preset load value；The data packet transmission quality of first wireless communication technique is unsatisfactory for the first data packet Transmission quality.Later under two kinds of strategies, when the communication equipment of the first wireless communication technique receives the first of transmitting terminal transmission After data packet, the first data packet is not transferred to receiving terminal at once, but first judges currently to pass by the first wireless communication technique Whether whether the load of transmission of data packet meet the transmission matter of the first data packet more than certain load value or data packet transmission quality Amount.

Step 102, the first data packet is transmitted to the communication equipment of the second wireless communication technique, to indicate the second channel radio First data packet is transferred to receiving terminal by the communication equipment of letter technology by the second wireless communication technique.

In order to enable not wasting the transfer resource between two communication equipments, the communication equipment of the first wireless communication technique exists Before executing this step, it can first judge whether that available second wireless communication technique transmits the first data packet, if it is available, just meeting The step of executing the forwarding.Specifically, the communication equipment of the first wireless communication technique may determine that the second wireless communication technique Whether communication equipment can be used, if it is available, then explanation can transmit the first data packet with the second wireless communication technique.First channel radio The communication equipment of letter technology can also judge and associated second wireless communication technique of the communication equipment of the first wireless communication technique Communication equipment on the data packet that caches whether be more than preset value, if be less than, illustrate that second can be used to wirelessly communicate skill Art transmits the first data packet.

Step 103, the first data packet is passed through the first wireless communication technique by the communication equipment of first wireless communication technique It is transferred to receiving terminal.

As it can be seen that in the embodiment of the present invention, during the first data packet is transmitted between transmitting terminal and receiving terminal, when first When communication equipment of the data packet Jing Guo the first wireless communication technique, if the transmission for the first data packet meets preset strategy When, the communication that the first data packet can be transmitted to the second wireless communication technique by the communication equipment of first wireless communication technique is set It is standby, to indicate that the first data packet is transferred to receiving terminal by the second wireless communication technique.In this way when cannot be by a kind of wireless When the communication technology transmits the first data packet, the first data packet is transmitted to the communication equipment of another wireless communication technique to pass It is defeated, Internet resources are sufficiently used, ensure that the transmission of data packet.

In a specific embodiment, the communication equipment of the first wireless communication technique is after performing above-mentioned steps 102, When receiving terminal receives the first data packet, then the confirmation message for first data packet can be returned to, then the first wireless communication The communication equipment of technology need to wait for receive receiving terminal by the communication equipment of the second wireless communication technique return for the After the confirmation message of one data packet, next data packet (i.e. the second data packet) of transmitting terminal transmission can be just transmitted, it specifically, can It, then can be by the first wireless communication technique by the second data packet to transmit the second data packet according to above-mentioned steps 100 to 103 It is transferred to receiving terminal, or the second data packet is transferred to receiving terminal by the communication equipment of the second wireless communication technique.If the The communication equipment of two wireless communication techniques does not receive the confirmation message of receiving terminal return, then can be by the second wireless communication technique Communication equipment retransmit first data packet, until the transmission of the first data packet is correct.In this case, in transmission data Bao Shi a, it is thus necessary to determine that data packet correctly after transmission, could transmit next data packet.

Refering to what is shown in Fig. 3, in another specific embodiment, the communication equipment of the first wireless communication technique is in execution After stating step 100, it is also necessary to execute step 104, i.e., when the communication equipment of the first wireless communication technique receives transmitting terminal hair After the first data packet sent, increase serial number for the first data packet, serial number is for identifying the first data packet and other data packets here Between ordinal relation.Then the communication equipment of the first wireless communication technique is after increasing serial number when executing step 102 One data packet is transferred to the communication equipment of the second wireless communication technique, to indicate that the communication equipment of the second wireless communication technique will increase The first data packet of serial number is added to be transferred to receiving terminal.Wherein when increasing serial number for the first data packet, the first wireless communication technique Communication equipment the first data packet can be associated with serial number after formed increase serial number after the first data packet；Or first by the first number It is segmented according to packet, and serial number is added in a certain sub- segmentation of the first data packet.

It carries in this way due to being transferred to each data packet of receiving terminal and identifies the suitable of the data packet and other data packets Order relation, transmitting terminal can not carry out transmission packet in sequence, and receiving terminal can be according to the corresponding serial number of each data packet The data packet of correct sequence is recombinated, then after executing above-mentioned steps 102, the communication equipment of the first wireless communication technique can be with Without waiting for the transmission of the first data packet it is correct after, i.e. the communication equipment of the first wireless communication technique withouts waiting for receiving pair In the confirmation message of the first data packet, so that it may to transmit another data packet (i.e. the second data packet), for the second data packet Transmission can be transmitted according to the step 100 to 104 in Fig. 3, and same for the transmission of the first data packet and the second data packet Shi Jinhang or sequence carry out, can be with speeding up data transmission rate.

In the present embodiment, during transmitting terminal delivers a packet to receiving terminal, when data packet passes through the first channel radio When the communication equipment of letter technology, carried out adding serial number by first data packet of communication equipment pair, in another specific embodiment, The data packet for having added serial number can be directly transmitted by transmitting terminal, the communication equipment in this way can directly forward data packet.

It should be noted that there is no absolute ordinal relations between step 104 and 101 in the present embodiment, it can be simultaneously It executes, can also sequentially execute, it is that one of which is specifically implemented to execute step 104 shown in Fig. 3 before step 101 Mode, in this way, if determining when being unsatisfactory for preset strategy to the transmission of the first data packet in a step 101, the second channel radio The first data packet for increasing serial number can be passed through the first wireless communication skill by the communication equipment of letter technology when executing step 103 Art is transferred to receiving terminal.

The embodiment of the present invention two

A kind of data pack transmission method is provided, it is (wireless with two kinds to be mainly used for various wireless communication technology as shown in Figure 1 For the communication technology) transmission for data packet in network system under fusion, the method for the present embodiment is the second nothing therein Method performed by the communication equipment of line communication technology, flow chart is as shown in figure 4, include：

It is appreciated that between transmitting terminal and receiving terminal when transmission packet (such as first data packet), the first data packet warp When crossing the communication equipment of the first wireless communication technique, according to the method described in above-described embodiment one can by with it is second wireless Communication interface between the communication equipment of the communication technology, the communication that the first data packet is transferred to the second wireless communication technique are set It is standby.

Step 202, the first data packet is transferred to receiving terminal by the second wireless communication technique.

As it can be seen that in the embodiment of the present invention, during the first data packet is transmitted between transmitting terminal and receiving terminal, the second nothing The communication equipment of line communication technology can receive the first data packet that the communication equipment of the first wireless communication technique is sent, first number It is to determine that the when of meeting preset strategy for the transmission of the first data packet is sent out by the communication equipment of the first wireless communication technique according to packet It send, the first data packet is transferred to receiving terminal by such second wireless communication technique.So that when a kind of wireless communication cannot be passed through When the first data packet of technical transmission, the first data packet is transmitted to the communication equipment of another wireless communication technique to transmit, Internet resources are sufficiently used, ensure that the transmission of data packet.

In a specific embodiment, the communication equipment of the second wireless communication technique is after performing above-mentioned steps 202, When receiving terminal receives the first data packet, then the confirmation message for first data packet can be returned to, then the second wireless communication The confirmation message can be sent to the communication equipment of the first wireless communication technique by the communication equipment of technology, can be transmitted down with instruction One data packet i.e. the second data packet, second wireless communication technique to be received such as communication equipment of the second wireless communication technique are led to Believe the second data packet that equipment is sent.

But if transmitting terminal is not to the confirmation message returned to the first data packet, the communication of the second wireless communication technique First data packet can be transferred to transmitting terminal by equipment again, when the number for transmitting the first data packet again is more than preset value (ratio Such as 12 times) when, the communication equipment of the second wireless communication technique needs to notify the communication equipment of the first wireless communication technique to initiate the The re-transmission of one data packet can just transmit the second data packet until the transmission of first data packet is correct.

As it can be seen that in the present embodiment, in transmission packet, it is thus necessary to determine that a data packet after transmission, could correctly be transmitted Next data packet, such receiving terminal just can know that the sequence for the data packet that transmitting terminal is sent.

Further, in another specific embodiment, the communication equipment of the first wireless communication technique can be the first number Increase serial number according to packet, which can indicate the ordinal relation between the first data packet and other data packets, in this case, the The communication equipment of two wireless communication techniques is the first data packet received after increasing serial number when executing above-mentioned steps 201, and When executing above-mentioned steps 202, the first data packet after increase serial number can be transferred to receiving terminal.

It carries in this way due to being transferred to each data packet of receiving terminal and identifies the suitable of the data packet and other data packets Order relation, receiving terminal can be according to the corresponding serial numbers of each data packet come recombination data, it may not be necessary to wait for the first data packet After transmission is correct, that is, the confirmation message that transmitting terminal returns is sent to by the communication equipment for withouting waiting for the second wireless communication technique The communication equipment of the communication equipment of first wireless communication technique, second wireless communication technique can wait another number to be received According to packet (i.e. the second data packet).In this case, the transmission of the first data packet and the second data packet is carried out at the same time or sequence It carries out, it can be with speeding up data transmission rate.
