Embodiment
The embodiment of the invention provide a kind of in GSM the method and apparatus of transmitting data service.The embodiment of the invention is provided with data transmission channel in the Traffic Channel of GSM; GSM user is by described data transmission channel transmitting data service.
Describe the embodiment of the invention in detail below in conjunction with accompanying drawing, the handling process of the described method of the embodiment of the invention comprises the steps: as shown in Figure 1
Step 1-1: the frame structure of TCH/FS and TCH/HS is divided into two parts: SubChannel0 and SubChannel1.
TCH/FS that defines in the GSM standard and the frame structure of TCH/HS are as shown in Figure 2, be made up of 26 TDMA (Time Division Multiple Access, time division multiplexing inserts) frame, wherein the 12nd frame is used to transmit a frame of following signaling channel, the 25th frame is an idle frame, does not transmit any data.
The embodiment of the invention is divided into two parts with the frame structure of above-mentioned TCH/FS and TCH/HS, thereby arranges two TCH/FS and TCH/HS channel: SubChannel0 and SubChannel1.The concrete dividing mode of SubChannel0 and SubChannel1 can be as shown in Figure 3, and promptly 0,2,4,6,8,10,12,13,15,17,19,21,23 frames of 26 multi-frames of TCH/FS and TCH/HS are combined into SubChannel0; 1,3,5,7,9,11,14,16,18,20,22,24,25 frames are combined into Subchannel1.
In actual applications, other dividing mode be can also adopt, SubChannel0 and SubChannel1 formed with other frame structure mode to the frame structure of above-mentioned TCH/FS and TCH/HS.
Step 1-2: SubChannel0 and SubChannel1 are distributed to individual consumer or one group of user, divide to be used in voice calls and data service.
Above-mentioned SubChannel0 and SubChannel1 can distribute to two different users among one group of user, and these two different users can come voice calls and data service with SubChannel0 and SubChannel1 respectively.Thereby be implemented under the situation of the Radio Resource that utilizes an identical frame, the two-way speech business can be provided.
In actual applications, above-mentioned SubChannel0 assignment can be become VGCS (Voice GroupCall Service, speech group calls in several business) channel, as one group of group-calling channel that the user is public, if there is this channel of CU to be used for conversation, SubChannel1 can be used for other user and sent data service this moment, realized multi-user shared Radio Resource.
Above-mentioned SubChannel0 and SubChannel1 can also bundle, and distribute to a user simultaneously.The schematic diagram that SubChannel0 and SubChannel1 are bundled as shown in Figure 4.Above-mentioned user can layout becomes GSM channel coding method VDTCH (Voice and Data Traffic Channel, a speech data Traffic Channel) channel of realizing that speech data transmits simultaneously with SubChannel1 with above-mentioned SubChannel0.SubChannel0 as Voice Traffic Channel (voice transfer channel), is used for transmitting half-rate or full-speed voice to call out; And SubChannel1 as DataTraffic Channel (data transmission channel), is used for transmitting data service.Thereby realized transmitting data service in voice calls.
When SubChannel1 is used for transmitting data service, continuous per 4 frames of Subchannel1 can be combined into a subchannel Sub-DTCH, this Sub-DTCH can adopt the code encoding/decoding mode of FACCH/F, is used for transmitting the 23Bytes data.
Utilize the handling process of the described method of the invention described above embodiment, thereby when can be implemented among the GSM voice calls, it is the data service transmitting-receiving demand of 4600bps that maximum rate is provided.
