Description
Technical field
The present invention relates to the digital cluster communication technology, refer to realize under a kind of digital cluster group receipts pattern the method for discontinuous reception (DRX, Discontinuous Reception) especially.
Background technology
The digital cluster communication net is the novel mobile communication system that rise at the twentieth century end, the digital cluster communication net can also be realized any communication between individual and colony except the personal mobile communication service that possesses institutes such as common mobile communication network such as global mobile communication (GSM) system, code division multiple access (CDMA) system and can provide.
Along with development and national economy, society is more and more higher to informationalized requirement, and the demand that adopts digital cluster system to build the command scheduling network becomes increasingly conspicuous.At present, in digital clustering communication system, GT800 (GSM Trunk 800M) with independent intellectual property right creatively combines time division multiple access access (TDMA) and Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) technology especially, brings the development of Chinese Digital Clustering into a new stage.GT800 is in conjunction with cellular telecommunication art, by optimization and the combination to the TDMA and the TD-SCDMA communication technology, for professional cluster user provides high-performance, jumbo cluster communication service; And it is stable that the GT800 trunked communication system has systematic function, continue by force, the fast advantages such as data service of performance and two-forty of the capability of sustainable development.
The mode of operation of Digital Clustering roughly comprises three kinds of idle pulley, dedicated mode and group receive mode, wherein, the user adds after the group calling in the group, enter group receive mode, the interior user of group this moment monitors the group calling down channel and comprises Traffic Channel and channel associated signalling channel, when the speaker was arranged, the hearer listened to speaker's speech; During no speaker, the hearer can carry out up taking and become the speaker according to channel associated signalling, enters speaker's dedicated mode.This shows that after group receive mode and group-calling channel foundation, portable terminal resides on the group-calling channel, answers speech or signaling.
In order to save the electric power of portable terminal, industry has proposed discontinuous reception (DRX) technology or group calling and has simplified notification channel and monitor (Reduced NCH monitoring) technology and come the monitoring of limiting mobile terminal.
Wherein, adopt the DRX technology to be roughly: to suppose that portable terminal resides at certain sub-district, and be in idle pulley, portable terminal obtains this mobile terminal affiliated paging group according to last 3 configuring conditions with the affiliated subdistrict paging channel of self IMSI, and then obtains the paging sub-channel positions of this paging group correspondence.Portable terminal is only monitored the beep-page message that the system on the paging subchannel that belongs to self broadcasts at one's leisure, and do not monitor the message of other paging group, outside, in order to reduce mobile terminal power consumption, adopt DRX mechanism to receive the beep-page message that described system broadcasts, like this, portable terminal is not being monitored under self during the paging group closed portion hardware device power supply to reach the purpose of economize on electricity.
Adopt Reduced NCH monitoring technology to be roughly: the group calling portable terminal must be by monitoring notification channel (NCH) to obtain the group calling notification message.Portable terminal is under idle pulley, portable terminal is according to the notification message sequence number (NLN in the paging channel (PCH), Notification List Number) whether changes decision and whether monitor the NCH channel, if NLN does not change, then portable terminal is not monitored the NCH channel, reduce mobile terminal power consumption with this, conservation of power.
But, in the existing digital clustering communication system, only when portable terminal is in idle pulley, can adopt DRX technology or Reduced NCH monitoring technology; And when being in group receive mode, portable terminal still adopts the mode of continuous reception.Be exactly specifically: under group receive mode, after portable terminal received busy up busy (UPLINK BUSY) message of expression up channel that network side sends, portable terminal entered up busy condition and receives speech at the TCH channel; Receive (UPLINK FREE) message of up free time of expression up channel free time when portable terminal after, portable terminal enters up idle condition and receives up channel state and message such as some pagings, notice, descending detection at the TCH channel.Though when up channel was idle, the signaling of transmitting on TCH was few, the time slot that has is empty, and portable terminal will receive continuously to all time slots of group-calling channel equally.
As seen, under digital cluster group receipts pattern, portable terminal is in always to be monitored or sending mode, has consumed a large amount of electric power of portable terminal at present.Especially for group calling private network user such as VPN resource reservation and railway shunting, airdrome control etc., because private network user group-calling channel is set up and during group-calling channel was set up, the private network user was few to up holding time, generally less than 50% always.Though can realize special channel special use like this, guarantee the reliability and the short calling of private network, because being in always, the private network user monitors or sending mode, very power consumption.
In sum, prior art only realizes DRX under portable terminal is in idle pulley, and under digital cluster group receipts pattern, portable terminal particularly private network user keeps all time slots of group-calling channel are received continuously always, make the power consumption of portable terminal on useless time slot is handled, can not rationally save the electric power of portable terminal, thereby be unfavorable for reducing mobile terminal power consumption.

Embodiment
Core concept of the present invention is: when network side judged that portable terminal enters up idle condition, the monitoring attribute that being used for of having set represented to monitor the encoding block of specifying multi-frame was carried in the discontinuous receiving notice message and sends to portable terminal; Portable terminal is then monitored the encoding block in the multi-frame of needs monitoring according to the monitoring attribute of carrying in this discontinuous receiving notice message, realized the discontinuous reception under the digital cluster group receipts pattern, and needn't monitor continuously all time slots of group-calling channel.The inventive method has rationally been saved the electric power of portable terminal, has reduced mobile terminal power consumption.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is described in more detail.
Fig. 1 is the implementation method flow chart that digital cluster group of the present invention is received pattern, and the inventive method may further comprise the steps:
Step 100: obtain the encoding block quantity of each multi-frame in the group-calling channel, and each encoding block and the multi-frame that obtains is provided with monitoring attribute.
Obtain the encoding block quantity of each multi-frame in the group-calling channel according to agreement regulation, this point belongs to technology as well known to those skilled in the art.What the present invention emphasized is that each encoding block and the multi-frame that obtains is provided with monitoring attribute.
Such as for GT800, the agreement regulation, channel associated signalling has taken the encoding block of group-calling channel 20ms, is mapped in 4 pulses at each encoding block of full speed channel coding back to send, and is mapped in 4 pulses to send behind the half-rate channel coding.And for the monitoring period 480ms of agreement regulation, because each tdma frame is 4.6ms, so, this monitorings period just is equivalent to 4 26 multiframe periods (26 * 4.6=120ms, 480ms/120ms=4 is individual).Comprise 1 frame idle frame, 1 frame signaling frame and 24 frame group-calling channels under the full rate in each 26 multi-frame, each multi-frame then comprises 24/4=6 encoding block so; Under the half rate, each 26 multi-frame is given two users and is used, and each user's 13 frame comprises channel associated signalling (SACCH) and 12 group-calling channels at a slow speed, and each 26 multi-frame comprises 12/4=3 encoding block so.And each encoding block and multi-frame be provided with label, as encoding block n, and multi-frame m etc.About this point, different digital cluster system related protocols have regulation, can no longer describe in detail here referring to related protocol.
Since dissimilar business to the signaling transmission speed require different, so require monitoring attribute also different.Monitor in the period at one, as need be at the railway shunting of the quick command transmitting in speech gap, business such as emergency disaster relief be because to the time-sensitive that continues, monitoring attribute can be set to monitor a plurality of encoding blocks to the very high business of signaling rate request; And business such as the ordinary clusters business not high to the signaling rate request can be provided with and only monitor an encoding block, save the electric power of portable terminal so more.With GT800 is example, under full rate, the monitoring attribute of the encoding block of each multi-frame can be set to shown in the table 1, table 1 is under the full rate, the encoding block corresponding monitoring attribute is provided with example table in certain multi-frame, in the table 1, suppose that encoded attributes is that 1 encoding block is represented and need be monitored, represent not need to monitor and encoded attributes is 0 encoding block.
| Encoding block 5 | Encoding block 4 | Encoding block 3 | Encoding block 2 | Encoding block 1 | Encoding block 0 |
| 0 | 0 | 0 | 0 | 1 | 1 |
Table 1
For another example, under half rate, the monitoring attribute of the encoding block of each multi-frame can be set to shown in the table 2, table 2 is under the half rate, the encoding block corresponding monitoring attribute is provided with example table in certain multi-frame, in the table 2, suppose that encoded attributes is that 1 encoding block is represented and need be monitored, represent not need to monitor and encoded attributes is 0 encoding block; Encoded attributes is that the encoding block of x represents it is invalid.
| Encoding block 5 | Encoding block 4 | Encoding block 3 | Encoding block 2 | Encoding block 1 | Encoding block 0 |
| x | x | x | 0 | 1 | 1 |
Table 2
And the multi-frame of monitoring for needs, the combination of the multi-frame of Jian Tinging as required, if 4 kinds of combinations are arranged then can adopt two incompatible expressions of character group, as shown in table 3, table 3 is that the multi-frame monitoring attribute is provided with example table.
| Implication | ||
| 0 | 0 | Monitor the 0th multi-frame of 4 * 26 multi-frames |
| 0 | 1 | Monitor the 0th, 1 multi-frame of 4 * 26 multi-frames |
| 1 | 0 | Monitor the 0th, 1,2 multi-frames of 4 * 26 multi-frames |
| 1 | 1 | Monitor the 0th, 1,2,3 multi-frames of 4 * 26 multi-frames |
Table 3
Step 101: when network side judges that portable terminal enters up idle condition, the monitoring attribute that sets is carried in the monitoring cell corresponding field of discontinuous receiving notice message and sends to portable terminal.
Digital Clustering is under the group receive mode, and agreement is defined in the up idle message that does not receive in certain monitoring period from network side, thinks that then portable terminal is in up busy condition; If receive up idle message, think that then portable terminal is in up idle condition.
When network side judges that portable terminal enters up idle condition, the monitoring attribute that sets in the step 100 is comprised the monitoring attribute of encoding block in each multi-frame and the monitoring attribute of each multi-frame, be carried in the monitoring cell corresponding field of discontinuous receiving notice message.Monitor cell and should comprise two fields at least: encoding block attribute field and multi-frame attribute field, wherein, the encoding block attribute field is used for being provided with the monitoring attribute of each each encoding block of multi-frame, can represent with a character string, encoding block of every correspondence of character string, the length of character string is by the quantity of encoding block decision at most in each multi-frame.For example, for GT800, comprise 6 encoding blocks under the full rate in each multi-frame, the encoding block attribute field should comprise 6 so; The multi-frame attribute field is used to be provided with the monitoring attribute of each multi-frame, can represent with a character string, and multi-frame of every correspondence of character string, the length of character string is by the quantity decision of multi-frame.For example, for GT800, comprise 4 multi-frames and monitor combined situation have 4 kinds, the multi-frame attribute field should comprise 2 at least so.
With GT800 is example, and under the full rate, monitoring cell can be as shown in table 4, and table 4 is under the full rate, monitors cell example table is set, and encoding block 0 and encoding block 1 in the 0th, 1 multi-frame of 4 * 26 multi-frames are monitored in the expression that is provided with of table 4 respectively.Wherein, monitor the monitoring attribute of the corresponding successively encoding block 5 of D7 position to D2 position difference of cell to encoding block 0, the D1 position and the D0 position of monitoring cell are used to be provided with the multi-frame monitoring attribute.
Table 4
Under half rate, monitoring cell can be as shown in table 5, and table 5 is under the half rate, monitors cell example table is set, encoding block 0 and encoding block 1 in the 0th multi-frame that expression monitoring 4 * 26 multi-frames are set of table 5.Wherein, the D7 position of monitoring cell is invalid to the D5 position, and corresponding successively encoding block 2 is to the monitoring attribute of encoding block 0 respectively in D4 position to D2 position, and the D1 position and the D0 position of monitoring cell are used to be provided with the multi-frame monitoring attribute.
Table 5
More than describe the composition of monitoring cell in detail and how monitoring attribute is set, to monitor cell afterwards is carried in the discontinuous receiving notice message and sends to portable terminal, the discontinuous receiving notice message of the present invention can be to have increased the existing UPLINK FREE message of monitoring cell newly, also can be to be exclusively used in to carry the dedicated notification message of monitoring cell.
When discontinuous receiving notice message employing has UPLINK FREE message, need be at network side newly-increased cell of monitoring in the UPLINK FREE message that portable terminal sends, when portable terminal receives UPLINK FREE message, also just received the monitoring cell like this; When discontinuous receiving notice message is dedicated notification message, when portable terminal receives dedicated notification message, also just received the monitoring cell.
Step 102: portable terminal is monitored the encoding block in the multi-frame of needs monitoring according to the monitoring attribute that monitoring cell in the discontinuous receiving notice message that receives carries, and needn't monitor continuously all time slots of group-calling channel.
If the monitoring cell that portable terminal receives is shown in above-mentioned table 4, so, portable terminal is only monitored encoding block 0 and the encoding block 1 in the 0th multi-frame of 4 * 26 multi-frames, and encoding block 0 in the 1st multi-frame of 4 * 26 multi-frames and encoding block 1, rather than all time slots of group-calling channel are received continuously.
Portable terminal is according to the monitoring cell that receives, multi-frame and encoding block that needs are monitored are monitored, the multi-frame and the encoding block that do not need to monitor are then abandoned monitoring, make under the group receive mode, portable terminal is realized discontinuous reception, rationally save the electric power of portable terminal, reduced mobile terminal power consumption.
Portable terminal is after the UPLINK BUSY message of receiving from network side, and portable terminal withdraws from the DRX pattern, and the up busy condition that enters group receive mode is monitored continuously to full-time crack.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
