In embodiments of the present invention, data are the transmission carried out between user equipment and network side equipment, the present invention A kind of transmission method for duplicate data that embodiment provides is all suitable for user equipment and network side equipment.
It should be noted that communication equipment using first carrying carry out current business when, in user equipment and net It needs to carry out data transmission between network side apparatus, therefore, when the communication equipment in the embodiment of the present invention is user equipment, this is logical Believe that the opposite end of equipment is just network side equipment；When the communication equipment in the embodiment of the present invention is network side equipment, which sets Standby opposite end is just user equipment.
In embodiments of the present invention, communication equipment can obtain corresponding first data packet of the first carrying, first carrying For the carrying used in ongoing communication service, first carrying for being carried as carrying data or signaling data bag.
Optionally, the first data packet can be Packet Data Convergence Protocol (PDCP, Packet Data Convergence Protocol protocol Data Unit (PDU, Protocol Data Unit), radio link layer control protocol (RLC, Radio) Link Control) PDU, medium access control (MAC, Media Access Control) PDU, the service data of PDCP The SDU of unit (SDU, Service Data Unit), the SDU of RLC or MAC.
Specifically, first, communication equipment obtains the former data packet for realizing the first carrying；Then, communication equipment is in former data Logic channel corresponding first identifier is set in packet, obtains the first data packet.That is, in embodiments of the present invention, communication The carrying of each of equipment can be transmitted by non-proprietary logic channel, but in each carrying (corresponding each industry Business) mark for the logic channel that the first data packet is transmitted for the first time, i.e. first identifier are provided in corresponding first data packet.
In this case, after communication equipment obtains the first data packet, which can exist the first data packet It is transmitted on different logic channels, i.e., communication equipment transmits the first data on preset at least one logic channel Packet, preset at least one logic channel include the corresponding non-proprietary logic channel of the first carrying.Specifically, by the first data Packet and the second data packet are transmitted on different non-proprietary logic channels, and after this, communication equipment can go to determine The carrier wave of first data packet is transmitted, the specific description process for the aft section in the embodiment of the present invention.
S102, detection the first data packet whether be the second data packet being transmitted across repetitive data packet.
Communication equipment is after obtaining corresponding first data packet of the first carrying, since the first data packet may be for the first time The transmission of progress, it is also possible to be the duplicate data for the second data packet for repeating to send, which is the first number of transmission According to the data packet for the new data that packet transmits before, therefore, which can detect whether the first data packet is to be transmitted across The second data packet repetitive data packet.If the first data packet is the data packet not being transmitted across, characterizing first data packet is New data；If the first data packet is the repetitive data packet for the second data packet being transmitted across, the number of first data packet is characterized According to being the duplicate data as the data of the second data packet having been transmitted through before.
Specifically, in embodiments of the present invention, communication equipment can record the record of each transmission data, in this way, should Communication equipment can detect the transmission data record before this time first data packet of transmission, search whether the with this transmission The identical data packet of one data packet transmitted.It wherein, can be with the identical data packet of the first data packet of this transmission It is the second data packet, can also be the repetitive data packet for the second data packet being transmitted across before.
It should be noted that in the transmission method of duplicate data provided in an embodiment of the present invention, communication equipment with this During the opposite end of communication equipment is communicated, in order to improve the reliability of transmission data, communication equipment can be directed to one The corresponding data packet of business carries out the transmission of number of repetition.What duplicate data provided in an embodiment of the present invention was just such to.
When S103, the repetitive data packet that the first data packet is the second data packet being transmitted across, determined according to preset rules It is used for transmission the first carrier of the first data packet, which is at least one of available carrier wave carrier wave；Preset rules are Judge the rule for transmitting the data packet with identical data on different carrier waves in preset time.
Communication equipment detect the first data packet whether be the second data packet being transmitted across repetitive data packet after, should Communication equipment can obtain two kinds as a result, one kind is：First data packet is the repetitive data packet for the second data packet being transmitted across, Another kind is：First data packet is the data packet not being transmitted across, i.e. new data.At this moment, when the first data packet has been transmitted across When the repetitive data packet of the second data packet, just characterization the first data packet at this time is exactly duplicate data, and therefore, communication equipment can be with It is determined according to preset rules and is used for transmission the first carrier of the first data packet, the object here is, will be by the in preset time One data packet is transmitted from the identical data that previous transmissions are crossed on different carrier waves, that is to say, that preset rules are sentenced in communication equipment It is scheduled on the rule for transmitting the data packet with identical data on different carrier waves in preset time.When the first data packet is new number According to data packet when, just carry out the transmission of first data packet using carrying.
It should be noted that in embodiments of the present invention, available carrier wave is what communication equipment can be used for carrying out data transmission Carrier wave.Preset time can carry out different definition according to the difference of preset rules.
In embodiments of the present invention, the current time of the first data packet is transmitted in current transmission time interval.
Under the premise of based on the repetitive data packet that above-mentioned first data packet is the second data packet being transmitted across, it is described below Specific communication equipment determines the process for the first carrier for being used for transmission the first data packet according to preset rules：
Optionally, the third data packet being transmitted across is the second data packet, or the third data packet that has been transmitted across is the The repetitive data packet of two data packets and the second data packet.
That is, before transmitting the first data packet, the third data packet being transmitted across can be the second data packet, i.e., New data can also be above-mentioned new data or carry out the duplicate data (duplication) of transmission again to changing new data.
(1), communication equipment obtains the second carrier wave of the third data packet being transmitted across；Communication equipment is true from available carrier wave Fixed any one carrier wave in addition to the second carrier wave is first carrier.
It should be noted that the second carrier wave is the carrier wave general designation for being transmitted across third data packet, may include at least one load Wave, specific number of carrier wave are to determine that the embodiment of the present invention does not limit according to the number of the carrier wave of actual transmissions third data System.The available carrier wave of communication equipment may be multiple carrier waves, which determines in addition to second from changing in available carrier wave Multiple carrier waves outside carrier wave, then determine any one carrier wave therein as first carrier from multiple carrier wave again, with The transmission of the first data packet is realized on the first carrier.
Here, preset rules can be B rules, i.e. communication equipment first transmits new data on a carrier wave, works as transmission It needs to transmit on the carrier wave for not all being transmitted across new data and duplication in the past when duplication data Duplication data.Alternatively, preset rules can be D rules, i.e., communication equipment first transmits new data on a carrier wave, It needs all be not transmitted across transmission duplication numbers on the carrier wave of the new data in the past when transmitting duplication data According to.
It should be noted that when preset rules can be B and D rules, preset time can be different Transmission Time Intervals.
(2), communication equipment obtains the first Transmission Time Interval of third data packet；First Transmission Time Interval is to work as forward pass When the previous Transmission Time Interval of defeated time interval, communication equipment determination from available carrier wave is any one in addition to the second carrier wave A carrier wave is first carrier；When first Transmission Time Interval is not the previous Transmission Time Interval of current transmission time interval, Communication equipment determines that any one carrier wave is first carrier from available carrier wave.
Here, preset rules can be A rules, i.e. communication equipment first transmits new data on a carrier wave, works as transmission It needs to transmit in upper primary be not transmitted across on the carrier wave of new data and duplication when duplication data Duplication data.Alternatively, preset rules can be C rules, i.e., communication equipment first transmits new data on a carrier wave, It needs to transmit duplication numbers in upper primary be not transmitted across on the carrier wave of the new data when transmitting duplication data According to.
It should be noted that when preset rules can be A and C rules, preset time can be different Transmission Time Intervals.
(3), when the first Transmission Time Interval is identical as current transmission time interval, communication equipment is determined from available carrier wave Any one carrier wave in addition to the second carrier wave is first carrier；First Transmission Time Interval is differed with current transmission time interval When, communication equipment determines that any one carrier wave is first carrier from available carrier wave.
