Method of the present invention be applicable to main frame to the handset downlink side to data passes, thereby be example with pan-European formula digital wireless communication (DECT) system, use the design of the frame and the structure of time slot of DECT system, illustrate under similar time-division multiple address system, tool is to implement the method that the present invention proposes.
Pan-European formula digital wireless communication (DECT) system correlation technique can be learnt in the file that ETSI (ETSI) worked out, and Fig. 1-4 is a brief description.Please refer to Fig. 1, it is the frame structure of pan-European formula digital wireless communication (DECT) system of the preferred embodiment of the present invention.
Wherein DECT is the wireless communication standard of Europe rule, belong to the planning of TDMA (time division multiple access) system standard and take 10 channels, each channel distribution is 24 time slots, be called a DECT frame, generally be formulated for 12 full duplex carryings (Full Duplex Bearers), 12 time slots are used for up link (Up Link) communication, and 12 time slots are used for down link (DownLink) communication.
As shown in Figure 2, each time slot in the DECT system comprises two partly, A-field (A-field): provide 48 as DECT agreement control signal, B-field (B-field): provide 320, with as sound/data/preposition control signal, wherein as shown in Figure 3, A-field (A-field) is divided into A-stem (A-header) and B-afterbody (B-tail) two parts again, and the A-stem is subdivided into TA-son field (TA-subfield), BA-son field (BA-subfield) and Q1, Q2 control bit (control bits) again again.As shown in Figure 4, wherein the BA-son field is to be used for specifying follow-up B-field contents.Generally on the DECT system used, sound was with U type (U-type), I
NThe format content transmission of grouping (Packet), data are then transmitted with the format content of E type (E-type).According to the proposed method, promptly be to utilize this BA-son field to flow to control sound.
Please refer to Fig. 5, it is the pronunciation receiver of receiving terminal of pan-European formula digital wireless communication (DECT) system of the preferred embodiment of the present invention.When communication protocol of the present invention (as described in next section) is complied with in the sending and receiving of data, determine a fixed time promptly to use which slot transmission data earlier, transmitting terminal is just put into the data of preparing to send the B-field of indivedual time slots, and the BA-son field with this time slot is set at the E-type simultaneously.This sets for idle originally time slot or specifies the reportedly defeated time slot of counting to have any impact originally, but to the time slot (promptly transmitting the time slot of sound) that originally is used to converse, its receiving terminal utilizes method of the present invention to use previous frame to exist the sound in the buffer to replace automatically, then receiving terminal is very natural ignores this segment data, thereby the user of conversation can't hear broken noise.Also can not adopt previous frame to exist the sound in the buffer to replace this segment data in addition, directly with quiet broadcast.
Please refer to Fig. 6, it is the communication protocol flow figure of pan-European formula digital wireless communication (DECT) system of the preferred embodiment of the present invention.Its communication process is as described below:
1. main frame and handset connect according to general DECT agreement (Protocol) program earlier, and are set at the kenel of transmission data.Then, main frame data-driven flow requirements is found out the present idle time slot and the time slot of conduct conversation usefulness.And which time slot is the notice handset have to use " frequency range resource (Bandwidth Resource) ".
2. after handset is received " frequency range resource (Bandwidth Resource) " information, can be according to its reception and disposal ability, the time slot that selection will be used, reply confirmation and give main frame " confirming frequency range resource (Bandwidth Resource Confirm) ", and be ready at these time slot receiving downlink datas.
3. main frame is received " confirm frequency range resource (Bandwidth Resource Confirm) ", can put into the time slot that handset is confirmed to the data that will transmit, and the B-field content format of setting these time slots is E-type.
4. specify the handset that will receive data so, can receive the data of down link at predetermined time slot.But not the handset of appointment (but the handset in the use of conversing) then utilizes aforesaid hardware designs auxiliary, can ignore this segment data automatically, and listen to the user with the sound playing that prestores.
When transfer of data with frame at interval, be transmitted in the 200ms (200 frame) at every turn, influence for sense of hearing is minimum, and in this 200ms, can receive burst (Burst) transmission rate that 2800 bytes are equivalent to 112Kbps for the Data Receiving terminal machine, use single slot transmission speed 32Kbps to increase by 3 times more than originally.
In sum, the group data transmission method that the present invention is provided in above preferred embodiment can improve the slow excessively shortcoming of data transmission bauds in routine techniques, and simplicity of design of the present invention is easy to implement, thereby is had actual application value.
Those skilled in the art can carry out various improvement under the situation that does not depart from the claim scope.
