Description
Technical field
The present invention relates to the technology of allocation of downlink channel in communication system, particularly a kind of indicating terminal receives the method for the down channel that data adopted.
Background technology
At present, communication system is being after the good down channel of terminal distribution sends data as GPRS (GPRS) system, may be for various reasons, switch as terminal leave, terminal call drop or communication system end to send data etc. to terminal, the temporary transient down channel free time can occur.When temporary transient down channel occurring during the free time, the other-end that communication system can be distributed to the down channel of free time communication system as early as possible uses, but because the time delay of transmission and allocation process process, idle down channel redistribution process need continue the time delay of 40 to 300 milliseconds (ms), is generally the time delay of 100ms.Use idle down channel for Yanzhong when this section, reduce the waste of telecommunication system resources, in communication system, proposed the descending dynamic assignment of forward direction (FDDA) technology.
The FDDA technology of communication system is to send the distribute data piece to terminal, whether 5 bits (bit) of temporary flow identity (TFI) are used to indicate corresponding down channel idle in the head of this distribute data piece, after terminal receives this distribute data piece, just can learn that according to TFI in the head of this distribute data piece communication system is the down channel that terminal is distributed immediately.
The FDDA technology of the employing communication system process of allocation of downlink channel immediately is made up of three steps: initialization, distribution and end.Initialization step is communication system network and FDDA process of starting terminal, the user no longer receives data by pre-assigned down channel during the FDDA process, and only accept the control of communication system network, the terminal that initialization step is used for notifying the current down channel that adopts the FDDA technology to distribute by communication system to receive data enters the FDDA working method, and all irrelevant terminals all can not receive data by this down channel during this period; The down channel that the allocation step control terminal uses communication system to adopt the FDDA technology to distribute receives data, is terminal and sends the distribute data piece that carries TFI, and indicating terminal receives the down channel that data adopted during the FDDA process; End step is that communication system sends the end data piece to terminal, terminal stops to receive data by the reception down channel that data adopted during the FDDA process, adopts pre-assigned down channel of communication system network or the employing down channel that communication system network is redistributed after FDDA process reception data before the FDDA process.
Fig. 1 does not adopt the FDDA technology for communication system in the prior art and adopts the FDDA technology to receive the contrast schematic diagram of data for the terminal distribution down channel, as shown in the figure: the left side one is listed as (comprise 8 down channels, promptly channel 0～7) greatly and represents communication system not use the FDDA technology; Two of centre and the right is listed as (comprise 8 down channels respectively, promptly channel 0～7) greatly and represents communication system to use the FDDA technology.In the B1 piece, communication system has been distributed to terminal with all down channels; In the B2 piece, vacated the down channel (channel 4 and channel 6) of two free time in the communication system; In the B3 piece, the left side one big row are not because communication system adopts the FDDA technology, so still there is the down channel (channel 4 and channel 6) of two free time, middle big row are because communication system has adopted the FDDA technology, so communication system has been distributed to the down channel 4 of free time the terminal of original use down channel 1, the one big row on the right have been because communication system has adopted the FDDA technology, so communication system has been distributed to the down channel 4 of free time and down channel 6 terminal of original use down channel 1.B1 piece among the figure is the setting up procedure of communication system FDDA process, and B2 piece and B3 piece are the allocation step of communication system FDDA process.
Below how which down channel indicating terminal adopts receive data during the FDDA process describes to the distribute data piece of communication system by carrying TFI.
TFI has 5 bit.At first in the setting up procedure of FDDA process, communication system network is the down channel that terminal is determined the current use of terminal, as fixed channel; Secondly, in the allocation step of FDDA process, communication system network sends the distribute data piece that carries TFI by fixed channel to terminal, corresponding successively in order 5 down channels that are higher than a value of fixed channel of 5 bit of TFI, 5 bit that are TFI are respectively b0, b1, b2, b3 and b4, fixed channel is TN, then the down channel of b0 correspondence is TN+1, the down channel of b1 correspondence is TN+2, the down channel of b2 correspondence is TN+3, the down channel of b3 correspondence is TN+4, the down channel of b4 correspondence is TN+5, if calculate by this, the down channel of 5 bit correspondences of TFI was greater than 7 o'clock (communication system had 8 down channels, channel 0～7), then to 7 deliverys, greater than 7 o'clock, the down channel of getting this bit correspondence was (TN+5) MOD 7 as the down channel TN+5 of b4 correspondence, and whether idle the present invention be provided with sign in 5 bit of TFI; At last, in the allocation step of FDDA process, terminal receives the distribute data piece that carries TFI by the communication fixed channel, the rule that employing sets in advance (this rule is provided with the regular identical of TFI with communication system), determine after receiving the down channel of data during the FDDA process, to receive data according to TFI by the down channel of determining.
Be provided with in 5 bit of TFI whether idle sign can adopt the binary number sign, for example, in each bit, " 0 " expression down channel is not idle; " 1 " sign down channel free time.The TFI that the middle as shown in Figure 1 distribute data piece that sends to terminal in being listed in the B2 piece greatly carries should be set to " 00100 ", represents only 4 free time of down channel, and terminal receives data by down channel 4 during the FDDA process; The right sends to the TFI that the distribute data piece of terminal carries in being listed in the B2 piece greatly should be set to " 00101 ", expression down channel 4 and 6 free time of down channel, terminal during the FDDA process by down channel 4 and down channel 6 reception data.
Adopt this mode marking terminal during the FDDA process, to receive down channel that data adopted and have the problem that can not cover the down channel that institute in the communication system might the free time, thereby coverage rate is not high, for Fig. 1, when descending channel after 0 free time, just can't identify, thereby can't during the FDDA process, adopt down channel 0 to receive data by indicating terminal, cause the waste of telecommunication system resources.

The present invention resets the down channel of the bit correspondence among the TFI, improves the coverage rate that covers the down channel that institute in the communication system might the free time.
In the present invention, at first, communication system network sends the distribute data piece carry TFI to terminal, TFI carry other bit channel bitmap map information one of them bit and carry other whether idle bit of indicated down channel respectively; Then, the channel bitmap map information that the terminal that receives the distribute data piece is carried according to one of them bit of TFI is determined the down channel of other bit correspondences, and according to other bit carry whether idle information is determined idle down channel, during the FDDA process, receive data by determined idle down channel.
Below with having 5 bit among the TFI for example, the present invention is described in detail.
Fig. 2 resets the schematic diagram of 5 bit of TFI for the present invention, as shown in the figure: these 5 bit are respectively bit0 in order, bit1, bit2, bit3 and bit4, communication system network is the down channel that terminal is determined the current use of terminal, as fixed channel, the channel bitmap mapping that bit0 carries back four bit is to begin or the information that odd number begins from the even numbers that is higher than/is lower than fixed channel successively, this information can adopt binary number representation, bit1, bit2, whether idle bit3 and bit4 carry indicated down channel information respectively, and this information also can adopt binary representation.Adopt this mode marking terminal during the FDDA process, receive down channel that data adopted with regard to can not exist can not cover in the communication system might be idle the problem of down channel.
The channel bitmap mapping that bit0 carries back four bit is to begin or during the information that odd number begins from the even numbers that is lower than fixed channel successively, the channel number of the down channel of the bit1 that might obtain, bit2, bit3 and bit4 indication is a negative, at this moment the negative channel number that obtains is taken absolute value, as the corresponding respectively down channel of back four bit.
In the present invention, the channel bitmap mapping that bit0 carries back four bit be successively from the even numbers that is higher than/is lower than fixed channel begin or the information that odd number begins even numbers or odd number can arbitrarily choose, but, be convenient to calculate the channel number of the down channel of other bit indications so preferably less than the maximum channel of the down channel in the wireless communication system number.Through statistics, it number is 7 o'clock that the maximum channel of 8 down channels and down channel is arranged in the wireless communication system, and adopting even numbers is 4, and odd number is that 1 effect that obtains is best, and the coverage rate that promptly covers the down channel that institute in the communication system might the free time is the highest.
Similarly, obtain down channel according to method provided by the invention, when the down channel of back four the bit correspondences among the TFI during,, obtain the actual corresponding down channel of bit to the down channel value delivery of communication system maximum greater than the down channel value of communication system maximum.As communication system 8 down channels are arranged, maximum down channel value is 7, and then the down channel value of back four bit correspondences of TFI to 7 deliverys, obtained the down channel of actual correspondence greater than 7 o'clock.
Certainly, the present invention also can indicate the channel bitmap map information of back four bit without bit0, and not comprising self the channel message bit pattern of other four bit with any indication among back four bit, whether idle other four bit that do not comprise self carry indicated down channel information.
In the present invention, can also be in TFI wherein carry other channel bitmap map informations among a bit, promptly according to other clocklike regular channel numbers of setting the indicated down channel of other bit, do not begin the information that still odd number begins and do not carry successively, in other bit, carry the whether idle information of indicated down channel from the even numbers that is higher than/is lower than fixed channel.Terminal is according to the indication rule that sets in advance, determines the down channel of other bit indications according to other channel bitmap map informations that carry among bit wherein.
Give one example and describe, the channel number of supposing fixed channel is TN, then bit0 is from TN+1 (comprising TN+1) for the mapping of " 0 " expression channel bitmap, the down channel that is the bit1 correspondence is TN+1, the down channel of bit2 correspondence is TN+2, the down channel of bit3 correspondence is TN+3, and the down channel of bit4 correspondence is TN+4; Bit0 is from TN+4 (comprising TN+4) for the mapping of " 1 " expression channel bitmap, and promptly the down channel of bit1 correspondence is TN+4, and the down channel of bit2 correspondence is TN+5, and the down channel of bit3 correspondence is TN+6, and the down channel of bit4 correspondence is TN+7.
Certainly, method provided by the invention also can for: suppose that fixed channel is TN, then bit0 is from TN-1 (comprising TN-1) for the mapping of " 0 " expression channel bitmap, the down channel that is the bit1 correspondence is TN-1, the down channel of bit2 correspondence is TN-2, the down channel of bit3 correspondence is TN-3, and the down channel of bit4 correspondence is TN-4; Bit0 is from TN-4 (comprising TN-4) for the mapping of " 1 " expression channel bitmap, and promptly the down channel of bit1 correspondence is TN-4, and the down channel of bit2 correspondence is TN-5, and the down channel of bit3 correspondence is TN-6, and the down channel of bit4 correspondence is TN-7.
The method that Fig. 3 provides for the employing embodiment of the invention is indicated the schematic diagram of down channel idle in the communication system, as can be seen from the figure, according to the difference setting of bit0 among the TFI, communication system might can be indicated to by idle down channel, do not exist indication less than problem.
In order to realize the present invention, reset the indication rule in advance in communication system each terminal, this indication rule method setting as described in Figure 2, when terminal receives the distribute data piece that carries TFI, just can determine down channel idle during the FDDA process according to the indication rule of resetting.
Fig. 4 is the method embodiment flow chart of the indicating terminal reception down channel that data adopted of the present invention, and its concrete steps are:
Here the state of terminal can switch for terminal and the sub-district, place.
Communication system network needs to consider that what and terminal of terminal wait reception data receive the service quality (QoS) of data when determining terminal, according to these factors, determine to distribute the terminal of idle down channel.
What be used to send initial data block can be set to fixed channel for a down channel of terminal distribution in advance, also can not be set to fixed channel, when the down channel that will send initial data block is not set to fixed channel, need in the TFI of initial data block, carry the channel number of fixed channel.
The TFI of initial data block also carries terminal iidentification, and this terminal is communication system network determines to distribute idle down channel during the FDDA process a terminal.
After step 403, terminal received the initial data block of indicating self by pre-assigned down channel, the down channel that stops in advance to be distributed received data, and definite fixed channel.
The process of determining fixed channel is: if initial data block is not carried the channel number of fixed channel, then terminal will be received the down channel of initial data block as fixed channel; If initial data block is carried the channel number of fixed channel, then terminal will receive and will have the down channel of channel number of the fixed channel that initial data block carries as fixed channel.
After step 405, terminal receive the distribute data piece by pre-assigned down channel, judge that whether the information of carrying first bit position among the TFI that this distribute data piece carries be that the channel bitmap mapping of back four bit is successively from being higher than the even numbers of fixed channel, if, execution in step 406; Otherwise, execution in step 407.
Step 409, communication system network are because after having sent or redistributed down channel with the data of terminal and having finished, stop the FDDA process, communication system network sends the end data piece that carries TFI to terminal, this TFI comprises that indication stops the sign of FDDA process, as all being set to 0.
Table 1 is the sign that initial data block, distribute data piece and end data piece carry.
