At problems of the prior art, a kind of brand-new group service implementation is proposed among the present invention, the TD-LTE technology is incorporated in the digital clustering communication system, thereby obtain digital clustering communication system, and realize group service based on this digital clustering communication system based on the TD-LTE technology.
Fig. 1 is for having the network architecture schematic diagram based on the digital clustering communication system of TD-LTE technology now.As shown in Figure 1, comprising: cluster user terminal, cluster broadband wireless access subsystem and cluster network subsystem etc.
Wherein, the cluster user terminal links to each other with cluster broadband wireless access subsystem or cluster network subsystem by air interface etc., for the user provides various PTTs (PTT, Push-To-Talk) speech business, broadband cluster multimedia service and scheduling feature.Described cluster user terminal comprises portable terminal, fixed station and dispatching desk etc.; Further, portable terminal also comprises hand-held travelling carriage and Vehicle mounted station, and dispatching desk also comprises wireless dispatching platform and wired dispatching desk.
Cluster broadband wireless access subsystem is made up of a plurality of enhancement mode eNodeB (E-eNodeB).Wireless colony scheduling feature module RTDF among the E-eNodeB (Radio Trunking Dispatch Function) is responsible for the relevant treatment of group service among the E-eNodeB, as, from enhancement mode mobile management entity eMME (MME, Mobility Management Entity) receives cluster control signaling, be called cluster user terminal place cell allocation down link shared resource, to be sent to called cluster user terminal etc. from the group service data flow that gateway (S-GW, Serving Gateway) receives.
Comprise eMME, S-GW, enhanced packet data network gateway eP-GW (P-GW in the cluster network subsystem, PDN Gateway), enhancement mode home subscriber server eHSS (HSS, Home SubscriberServer) and the scheduling gateway (D-GW, Dispatch Gateway).Wherein, cluster control function module (TCF among the eMME, Trunking Control Function) is the control centre that realizes trunked call, is responsible for the authentication of cluster user and the mandate of group service, set up the carrying of transmit traffic data stream for the user of authentication success; Cluster block functions module (TPF among the eP-GW, Trunking Packet Function) be used to finish the group service data flow mapping, duplicate and distribute, and according to the business characteristic of user's request and the foundation of service quality (QoS, Quality of Service) demand initiation service bearer; Cluster user server among the eHSS (TSS, Trunking Subscriber Server) is used to store the group user profile relevant with group service with management; D-GW is the gateway of wired dispatching desk access set group network subsystem, is responsible for the authentication of wired dispatching desk, the signaling between wired dispatching desk and the cluster network subsystem and the transmission of business datum; In addition, D-GW also is responsible for realizing interconnecting of this group system and other group system.
After adopting digital clustering communication system shown in Figure 1, group service will be carried in the packet domain, therefore can be completely achieved sharing of Traffic Channel, thereby will improve resource utilization greatly, and then reduce the operation cost of digital clustering communication system.And because the TD-LTE technology adopts the all-IP flattening network architecture, the base station directly links to each other with core net, so the minimizing of the network side interior signaling interaction in the call establishment, and call set-up time is shortened.
But, also can there be certain problem in digital clustering communication system shown in Figure 1 in actual applications, such as: though the network architecture of TE-LTD technology can make call set-up time shorten, but in the TD-LTE technology, the Paging Control Channel cycle of air interface is longer, and can not revise, therefore, cause call set-up time still longer; In addition, existing TD-LTE technology designs at point-to-point communication service, and group service is more a kind of business to multiple spot, therefore can't directly be applied in the group service having the TD-LTE technology now.
, in the scheme of the present invention, the air interlace channel in the existing TD-LTE technology is made amendment for this reason, increase new logic channel and new transmission channel.Stipulate in the air interface protocol of TD-LTE technology, by MAC layer (MAC, Media Access Control) provide the data transport services on the logic channel, different data transport services kind (point-to-point and point-to-multipoint etc.) needs corresponding different logical channel type.Therefore, in the scheme of the present invention,, newly-increasedly be used to carry the descending logic channel of clustered paging control information at long problem of Paging Control Channel cycle of air interface, be defined as clustered paging control channel (TPCCH, Trunking Paging Control Channel).The foundation of TPCCH channel has reduced the paging channel cycle of air interface.At the characteristics of group service point-to-multipoint, the newly-increased descending logic channel that is used for control informations such as group service call setup, calling release and right of speech notice is defined as cluster control channel (TCCH, Trunking Control Channel); And the newly-increased descending logic channel that is used to transmit cluster point multipoint message traffic data message, be defined as group service channel (TTCH, TrunkingTraffic Channel).In addition, transmission channel is used to carry the business information that is provided by physical layer, it is transferred to MAC layer and high level, what describe is the feature of transfer of data on the air interface, in the scheme of the present invention, according to the characteristics of TPCCH channel, the newly-increased transmission channel that is used to carry the TPCCH channel, be defined as clustered paging transmission channel (TPCH, Trunking Paging Channel).The TPCH channel has following feature: it can be dynamic broadcasting, be mapped to physical resource in whole group of overlay area of sub-district, and supports discontinuous reception (DRX, Discontinuous Reception) pattern etc.Can the send opportunity and transmission cycle of TPCCH channel be notified to each cluster user terminal by system broadcast message, so, the Paging Control Channel cycle that is used for group service of air interface can be provided with arbitrarily as required, thereby has shortened the call set-up time of group service.
Fig. 2 is that the downlink map that the present invention is based in the digital clustering communication system of TD-LTE technology concerns schematic diagram, is divided into descending logic channel, descending transmission channel and down physical channel.Newly-increased TPCCH, TTCH and TCCH belong to descending logic channel, and newly-increased TPCH belongs to descending transmission channel.As shown in Figure 2, the mapping approach of TPCCH channel is: TPCCH channel-TPCH channel-Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel); The mapping approach of TCCH channel is: TCCH channel-downlink shared transmission channel (DL-SCH, Downlink shared channel)-PDSCH channel; The mapping approach of TTCH channel is: TTCH channel-DL-SCH channel-PDSCH channel.Schedule information with TPCCH channel, TCCH channel and TTCH channel is loaded on the PDSCH with each tagging respectively.Each cluster user terminal detects PDCCH, searches corresponding transmission block TB according to the schedule information that finds at the PDSCH channel.Wherein, the message transmission between PDCCH and the PDSCH is the prior art of TD-LTE technology, just repeats no more at this.The effect of other channel shown in Figure 2 and mapping relations are known in this field, repeat no more; In addition, identical in uplink map relation and the prior art.
Stipulate in the air interface protocol of TD-LTE technology, dissimilar logic channels need pass through Radio Network Temporary Identifier (RNTI, Radio Network Temporary Identifier) distinguishes, as Paging Control Channel (PCCH, Paging control channel) utilize paging RNTI (P-RNTI) to distinguish, Dedicated Traffic Channel (DTCH, Dedicated Traffic Channel) utilizes sub-district RNTI (C-RNTI) to distinguish; For newly-increased TPCCH channel, TCCH channel and TTCH channel, need be the corresponding sign of its definition equally, so that distinguish with other logic channel, stipulate in the scheme of the present invention, utilize clustered paging RNTI (TP-RNTI) to come the TPCCH channel is distinguished; Utilize group service RNTI (G-RNTI) to come TCCH channel and TTCH channel are distinguished, aloft with different logical channel number (LCID) TCCH channel and TTCH channel are distinguished in interface layer two agreements.
Based on above-mentioned introduction, Fig. 3 is the flow chart of clustering service implementation methods embodiment of the present invention.As shown in Figure 3, may further comprise the steps:
Step 301: each cluster user terminal periodically detects on appointed positions with TP-RNTI sign carries out PDCCH channel after cyclic redundancy check (CRC) (CRC, the Cyclic Redundancy Check) scrambling.
In actual applications, the base station can be passed through broadcast in advance, the TPCCH channel information is informed each cluster user in the send opportunity and the transmission cycle of network side, described send opportunity is meant the transmission positional information of TPCCH channel, be about to the TPCCH channel bearing and send on which subframe of which radio frames (being the PF frame), described subframe is generally the P0 subframe.Follow-up, when the informational needs of TPCCH channel bearing sent, the base station promptly can send (on the follow-up PDSCH of the being mapped to channel) on the above-mentioned appointed positions.
After each cluster user receives the broadcast that the base station sends, at the PDCCH channel that periodically detects on the appointed positions after carrying out the CRC scrambling with the TP-RNTI sign; Carry the schedule information of TPCCH channel on the PDCCH channel, be used to indicate the position of transmission of Information piece (TB, Transport Block) on the PDSCH channel that comprises the TPCCH channel bearing.
Step 302:, then find the TB that is carried on the information that comprises the TPCCH channel bearing on the PDSCH channel according to described schedule information if carry the schedule information of TPCCH channel on the PDCCH channel.
In this step, if determine to carry on the PDCCH channel schedule information of TPCCH channel, then each cluster user terminal utilizes known TP-RNTI that described schedule information is carried out the CRC descrambling, get access to the positional information of TB on the PDSCH channel of the information that comprises the TPCCH channel bearing, and find the TB of TPCCH channel correspondence according to the positional information that gets access to.How the cluster user terminal knows that TP-RNTI is known in this field, repeats no more.
Step 303: the TB that finds is deciphered.
In this step, the cluster user terminal is deciphered the TB that finds, and with the result of decoding success, promptly MAC Packet Data Unit (PDU, Packet Data Unit) is transferred to high level.How to be decoded as prior art, to repeat no more.If decoding failure then abandons the TB that finds.
Step 304: according to decode results, the high level of each cluster user terminal is judged the member who self whether belongs in the current group service of initiating respectively, if then set up the control plane passage of cluster control.
To carry information such as the group ID of group service and G-RNTI sign among the MAC PDU of correct decoding, because it is known in advance self belonging to which group, so, each cluster user terminal can be determined the member who self whether belongs in the current group service of initiating by the group id information, if, then set up the control plane passage of trunked call, otherwise, the MAC PDU that receives abandoned; The G-RNTI sign is used to illustrate the TCCH channel of the current group service correspondence of initiating.
Wherein, setting up the control plane passage comprises: set up TCCH channel relevant entity and context; The entity that described TCCH channel is relevant comprises: PDCP (PDCP, Packet DataConvergence Protocol) entity, radio link control (RLC, Radio Link Control) entity, MAC entity and physical layer (PHY, Physical) entity.How to be established as known in this fieldly, to repeat no more.
Step 305: after called cluster user terminal is set up the TCCH control plane passage of trunked call, PDCCH channel after detection is carried out the CRC scrambling with G-RNTI in each Transmission Time Interval of control plane passage (TTI, Transmission Time Interval).If detect the schedule information that carries the TCCH channel on the PDCCH channel, then search the TB that is carried on the information that comprises the TCCH channel bearing on the PDSCH channel, and the TB that finds is deciphered according to described schedule information.And the control information of correct decoding transferred to high level.If decoding failure then abandons the control information that finds.
Called cluster user carries out operations such as corresponding trunked call foundation or release according to the control information of TCCH.
Step 306: after the control information that correctly receives the TCCH channel, cluster user will carry out the configuration and the foundation of service plane passage.The service plane passage that the utilization of caller cluster user terminal is set up is initiated speech; Called cluster user terminal detects in each TTI with G-RNTI carries out PDCCH channel after the CRC scrambling, if detect the schedule information that carries the TTCH channel on the PDCCH channel, then search the TB that is carried on the information that comprises the TTCH channel bearing on the PDSCH channel, and the TB that finds is deciphered according to described schedule information.
After correctly receiving the TCCH channel information, calling and called cluster user terminal can begin to upload or receive the group service data message.Specifically, the service plane passage that the utilization of caller cluster user terminal is set up is initiated speech, called cluster user terminal then detects in each TTI with G-RNTI carries out PDCCH channel after the CRC scrambling, if on the descending assignation information of certain TTI, detect the schedule information that carries the TTCH channel on the PDCCH channel, then utilize the G-RNTI descrambling that gets access in the step 304 to go out this schedule information, and search the TB that is carried on the information that comprises the TTCH channel bearing on the PDSCH channel according to this schedule information, and the TB that finds deciphered, with the result of decoding success, the MAC PDU that promptly carries the group service data message is transferred to high level.
Follow-up, periodicity based on group service, for saving electric weight, each called cluster user terminal can all not detect each TTI, carry out PDCCH channel after the CRC scrambling but periodically detect, and, search the TB that is carried on the information that comprises the TTCH channel bearing on the PDSCH channel according to the schedule information of detected TTCH channel with G-RNTI sign, the TB that finds is deciphered, give the result transmission of decoding success high-rise.
That is to say that called cluster user terminal is after detecting the PDCCH channel first, follow-up can all the detection each TTI again, but have periodic characteristics according to group service detected the PDCCH channel in the same position of next cycle and got final product.For acyclic business, then need each TTI is all detected.
In addition, after the right of speech of caller cluster user terminal is seized, all called cluster user terminals, comprise original caller cluster user terminal and other called user terminal except that the called user terminal of seizing right of speech, again in each TTI, detect with the G-RNTI sign and carry out PDCCH channel after the CRC scrambling, if detect the schedule information that carries the TTCH channel on the PDCCH channel, then search the TB that is carried on the information that comprises the TTCH channel bearing on the PDSCH channel according to this schedule information, and the TB that finds deciphered, give the result transmission of decoding success high-rise; Afterwards, detection is carried out PDCCH channel after the CRC scrambling with G-RNTI sign, and according to the schedule information of detected TTCH channel, searches the TB that is carried on the information that comprises the TTCH channel bearing on the PDSCH channel, the TB that finds is deciphered, give the result transmission of decoding success high-rise.
Also can carry out PDCCH channel after the CRC scrambling to periodically detecting with G-RNTI sign, and according to the schedule information of detected TTCH channel, search the TB that is carried on the information that comprises the TTCH channel bearing on the PDSCH channel, the TB that finds is deciphered, give the result transmission of decoding success high-rise.
