Abstract
The invention discloses a method, a terminal, a base station and a system for backward channel signal transmission. The method is applied to the terminal and comprises the following steps: determining a backward channel set based on channels distributed by the base station, determining a target channel from the backward channel set according to a preset backward channel signal transmission policy, and monitoring the target channel so as to receive backward channel signals transmitted by the base station according to the backward channel signal transmission policy. By means of the technical scheme, when the terminal makes a call, no backward channels need to be monitored all the time, only the target channel needs to be monitored according to the backward channel signal transmission policy so that the time for terminal monitoring is shortened, and power consumption is reduced. Meanwhile, the base station does not need to transmit the backward channel signals periodically, but instead only needs to transmit the signals in the target channel according to the backward channel signal transmission policy. Therefore, the same backward channel signal only needs to be transmitted once, system resources of the base station can be saved, and resource waste can be avoided.
Description
Technical field
The present invention relates to the field of signal transmissions of base station and terminal room in communication system, particularly the methods, devices and systems of backward channel signalling in a kind of time division multiple access (TDMA) system.
Background technology
In communication system, the base station is except completing the transmission with the voice messaging of the terminal room of current transmitting business or data message, also need to send signaling to control the terminal switch operating behavior of current transmitting business, stop launching and return to accepting state, rising or reduce power etc. as control terminal.And adopt in the digital communication system of semiduplex mode in terminal, terminal can't receive the control signal of base station down in emission process.The technical way that addresses this problem at present is the TDMA technology.In tdma system, terminal is at a time slot emission uplink information, and next time slot receives downlink information; Between terminal and base station, transmitting voice information or data message adopt Traffic Channel, and terminal receives the control signal employing backward channel different from Traffic Channel that the base station sends.Therefore, this control signal is also referred to as the backward channel signaling.
The structure of the base station down interface frame that usually adopts as shown in Figure 1, comprises that 3 kinds of data blocks consist of.Wherein, the general statements channel provides the channel characteristics sign, and voice-and-data block of information voice-bearer or data message are shared and can be selected embedding synchronization character, link control signal or a backward channel signaling in data block.
Because the backward channel signaling is sent to terminal by the base station, terminal can not determine when the base station sends control signaling, and therefore, terminal needs to monitor backward channel to receive the backward channel signaling after making a call and connecting with the base station.And in order to make terminal needn't monitor each backward channel to receive the backward channel signaling, existing mode is that the base station sends the backward channel signaling by periodicity, after terminal listens to the transmission position of backward channel signaling for the first time, the beginning cycle count, and send on the position in corresponding backward channel signaling according to the cycle that the base station sends and monitor backward channel.
The inventor finds in long-term research process, by above-mentioned existing mode, although can reduce the number of times of terminal monitoring backward channel,, on the one hand, angle from terminal, in this mode, the terminal business that at every turn makes a call all must be monitored backward channel and search for the transmission position of backward channel signaling in the very first time, to determine the starting point of cycle count, so, terminal is monitored time of backward channel when making a call longer, and power consumption is larger; On the other hand, angle from the base station, when the base station need to send the backward channel signaling each time, in this mode, the base station must periodically repeatedly be launched this backward channel signaling guarantee terminal and can accurately be received this backward channel signaling, like this, during due to each backward channel signaling of transmission, the base station will repeatedly be launched, so the number of times of base station emission backward channel signaling causes the waste of base station system resource greater than the quantity of the backward channel signaling of actual needs transmission.

Embodiment
Below we in connection with accompanying drawing, optimum implementation of the present invention is described in detail.At first it is to be noted, the implication of the term of using in the present invention, words and claim can not only only limit to its literal and common implication and go to understand, the implication and the concept that also comprise and then conform to technology of the present invention, this is because we are as the inventor, to suitably provide the definition of term, in order to the most appropriate description is carried out in our invention.Therefore, the configuration that provides in this explanation and accompanying drawing is first-selected embodiment of the present invention, rather than will enumerates all technical characteristics of the present invention.We will recognize to also have various equivalent scheme or the modifications that can replace our scheme.
Basic thought of the present invention is: identical backward channel signalling strategy is set in terminal and base station in advance; When terminal made a call, the destination channel that terminal is only monitored in the backward channel set according to backward channel signalling strategy received the backward channel signaling; When the base station sends the backward channel signaling to terminal at needs, only send the backward channel signaling to terminal in destination channel according to backward channel signalling strategy.Like this, terminal can be monitored other backward channel, and the base station also only needs to send once for identical backward channel signaling.
Below in conjunction with accompanying drawing, describe the specific implementation of the method for backward channel signalling of the present invention in detail by specific embodiment.
Shown in Figure 2 is the basic flow sheet of the embodiment of the method one of backward channel signalling of the present invention, and the method is applied to terminal, comprises the steps:
When terminal made a call, the terminal request base station was the channel that terminal distribution is communicated by letter between the two; The base station is according to the request of terminal, for terminal distribution goes out channel; Fast mobile terminal is to the channel of base station assigns, and all channels that will distribute are divided into some Traffic Channels and some backward channels, then all backward channels are defined as the backward channel set.Wherein, backward channel and Traffic Channel are spaced, as shown in Figure 3; The base station is the channel of terminal distribution, can be traffic channel, can be also Packet Data Channel.
Need to prove, Traffic Channel and backward channel are that the base station is determined for terminal for the terminal distribution channel time, and terminal is to determine Traffic Channel and backward channel according to the distribution of base station when being assigned to channel.
Backward channel signalling strategy is preset in terminal and base station simultaneously.After terminal was determined the backward channel set, the backward channel that is used for transmission backward channel signaling with appointment in backward channel signalling strategy was defined as destination channel.The backward channel signaling all will be received in destination channel.
Need to prove, backward channel signalling strategy can have multiple, only needs identical the getting final product of destination channel that is used for sending and receiving backward channel signaling that guarantees that terminal and base station are determined according to this strategy.In the present embodiment, provide two kinds of backward channel signalling strategies to come performing step 202.
Step 202 execution mode that the first strategy is corresponding is specially: from described backward channel set, will specify the emission channel next backward channel afterwards of uplink information to be defined as described destination channel; Described appointment uplink information has the frame type of appointment or the content frame of appointment.
Step 202 execution mode corresponding to the second strategy comprises as shown in Figure 4:
Step 401, terminal will specify the emission channel next backward channel afterwards of uplink information to be defined as the initial target channel from described backward channel set; Described appointment uplink information has the frame type of appointment or the content frame of appointment.
Whether step 402, the described initial target channel of terminal judges are the backward channel that receives synchronization character; If so, enter step 403, if not, enter step 404.
Step 403, terminal are defined as described destination channel with the next backward channel after initial target channel described in described backward channel set.
Step 404, terminal are defined as described destination channel with described initial target channel.
Need to prove, in above-mentioned two kinds of strategies, specifying uplink information can be any uplink information of terminal emission, only needs identical the getting final product of appointment uplink information that guarantees that terminal and base station are all determined; The mode of uplink information appointment can be the frame type of specifying uplink information, be that in voice E frame, Packet Data Channel, the appointment uplink information is grouped data tail frame as specifying uplink information in traffic channel, can be also the content of specifying uplink information, as specifying the frame count value of uplink information.
In addition, the second strategy is for the backward channel that solves synchronization character in traffic channel and the afoul problem of backward channel of backward channel signaling.As shown in Figure 5, in traffic channel, in the backward channel of a typical voice superframes, first frame is for receiving the backward channel of synchronization character, be used for base station and terminal synchronizes, remaining backward channel can be used for receiver control signal or backward channel signaling, and in addition, in a superframe, general needs a backward channel receive the backward channel signaling.The backward channel that sends the backward channel signaling when the base station is that when sending the backward channel of synchronization character, a transmission can only be selected in the base station in both in this backward channel just, and another signaling can only be deferred to next backward channel transmission.Present prior art, base station and terminal all send and monitoring reception backward channel signaling with cycle count, therefore, the base station is when either-or, due to terminal not other backward channels beyond the listening period count value receive the backward channel signaling, so the base station can only send the backward channel signaling at this backward channel, otherwise terminal can not receive the backward channel signaling.And owing to only having the backward channel of a synchronization character in a voice superframes, so synchronization character will be deferred to next backward channel and send.In this case, although can guarantee that terminal receives the backward channel signaling, but send continually the reliability decrease that the backward channel signaling can cause channel synchronization and mistaken diagnosis to detect, especially in the situation that terminal roaming local base station under the nonterminal, the base station is after the corresponding frame of control channel replaces synchronization character with the backward channel signaling, when if roaming terminal searches control channel just, will ignore this base station owing to finding no the effect synchronization character.
And the second strategy in employing the present embodiment need to select one when sending in synchronization character and backward channel signaling when the base station, first sends synchronization character, and then next backward channel sends the backward channel signaling again; Simultaneously, if receive synchronization character in the backward channel of terminal monitoring, continue to monitor next backward channel to receive the backward channel signaling.Like this, both can guarantee that terminal received the backward channel signaling that the base station sends, the problem that can also avoid above-mentioned first delayed delivery synchronization character to cause.For these reasons, the backward channel signalling strategy in traffic channel preferably adopts above-mentioned the second strategy.
And for Packet Data Channel, the backward channel that sends the backward channel signaling when the base station and the backward channel of transmission synchronization character are lucky when identical, synchronization character in this backward channel directly can be replaced with the backward channel signaling.As shown in Figure 6, there are a plurality of backward channels to be used for the sending and receiving synchronization character in Packet Data Channel in grouped data, so, the synchronization character in one of them backward channel can not affected synchronous between terminal and base station.Therefore, the backward channel signalling strategy in Packet Data Channel preferably adopts the less above-mentioned the first strategy of execution in step.
Then return to Fig. 2, after step 202 is complete, execution in step 203.
Owing to also having preset backward channel signalling strategy in the base station, the base station only sends the backward channel signaling according to backward channel signalling strategy in destination channel, and therefore, terminal is only monitored destination channel, can guarantee to receive the backward channel signaling.
Need to prove, the technical scheme of the present embodiment both can be applied in the tdma system of structure of time slot of alignment, also can be applied in the tdma system of structure of time slot of skew.
Technical scheme by the present embodiment, base station and terminal are by presetting identical backward channel signalling strategy, thereby terminal only need to be monitored the backward channel of appointment in strategy, just can receive the backward channel signaling, and need to not monitor all backward channels when making a call, therefore, the time of terminal monitoring backward channel is shortened, and power consumption is minimized.Simultaneously, when the base station sends the backward channel signaling at needs, only need to send once on the backward channel of appointment according to strategy, just can guarantee that terminal receives this backward channel signaling, and do not need periodically repeatedly to send identical backward channel signaling, therefore, the resource of base station is saved, and has avoided the waste of resource.
In addition, in the time of can also synchronization character conflicts mutually with the transmission of backward channel signaling in traffic channel in the present embodiment, guaranteeing that terminal can receive the preferential synchronization character that sends under the prerequisite of backward channel signaling, avoiding the problem of the reliability decrease that channel synchronization that the synchronization character delayed delivery causes and mistaken diagnosis detect.
Corresponding to the embodiment of the method that is applied to terminal, the present invention also provides a kind of embodiment of the method two of backward channel signalling, is applied to the base station, as shown in Figure 7, comprises the steps:
Step 701, base station are the terminal distribution channel according to the request of terminal, so that the set that the backward channel that terminal obtains distribution forms is defined as the backward channel set.
Step 702, base station according to the backward channel signalling strategy that presets from for determining destination channel the described backward channel of described terminal distribution.
Wherein, should for the described backward channel of described terminal distribution, be namely the backward channel in the determined backward channel set of terminal.
Two kinds of backward channel signalling strategies are provided in the present embodiment.
The execution mode of the step 702 that the first strategy is corresponding comprises: from for the described backward channel of described terminal distribution, will specify the receive channel next backward channel afterwards of uplink information to be defined as described destination channel; Described appointment uplink information has the frame type of appointment or the content frame piece of appointment.
The execution mode of the step 702 that the second strategy is corresponding comprises as shown in Figure 8:
Then return to Fig. 7, after step 702 is complete, enter step 703.Step 703, base station send the backward channel signaling to terminal in described destination channel, so that described terminal receives described backward channel signaling according to described backward channel signalling strategy.
For the embodiment of the method two that is applied to the base station, because it corresponds essentially to the embodiment of the method one of terminal, so relevant part gets final product referring to the description of the embodiment of the method one of terminal.
Technical scheme by the present embodiment, base station and terminal are by presetting identical backward channel signalling strategy, thereby the base station is when needs send the backward channel signaling, only need send once on the backward channel of appointment according to strategy, the resource of base station is saved, and has avoided the waste of resource.Simultaneously, terminal only need to be monitored the backward channel of appointment in strategy, and the time of terminal monitoring backward channel is shortened, and power consumption is minimized.In addition, can also avoid the problem of the reliability decrease that channel synchronization that the synchronization character delayed delivery causes and mistaken diagnosis detect in the present embodiment.

Whether step 910, terminal judges initial target channel are the backward channel that receives synchronization character, if, enter step 911, if not, enter step 912: owing to monitoring the initial target channel in step 904, therefore, if judgment result is that of step 906 is, after step 907 was finished, terminal will receive synchronization character in the initial target channel, can judge that thus the initial target channel is the channel that receives synchronization character; Otherwise terminal does not receive synchronization character at the initial target channel, and result of determination is no.
