Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

The system of embodiment of the present invention transmission Burst Period business comprises: first user equipment and receiving equipment.

First user equipment, for being sent the initial data packets of Burst Period business to receiving terminal by first resource, wherein said first resource is based on seizing or the pre-assigned resource based on dedicated channel; After sending described initial data packets by described first resource to receiving terminal, sent the follow-up data bag of described Burst Period business by Secondary resource to receiving terminal, wherein said Secondary resource is the common transmission resource based on scheduling;

Receiving equipment, for being received the initial data packets from the Burst Period business of first user equipment by first resource, wherein said first resource is based on seizing or the pre-assigned resource based on dedicated channel; After receiving described initial data packets by described first resource, receive the follow-up data bag from the described Burst Period business of first user equipment by Secondary resource, wherein said Secondary resource is the common transmission resource based on scheduling.

Current system available resources are divided into two parts by the embodiment of the present invention, and a part is based on seizing or pre-assigned dedicated transmissions resource, i.e. first resource; Another part is the common transmission resource of side apparatus Network Based scheduling, i.e. Secondary resource.Two parts resource is separated in frequency aspect, as shown in Figure 2 A.The employing of Burst Period business first arrival bag to be seized or pre-assigned private resource transmits, and the Bao Ze of follow-up arrival is transmitted in common transmission resource.Doing reason like this, to be that mode resource frequency resource utilance is seized or allocated in advance in employing very low, therefore for the first arrival data packet transmission of Burst Period business, wait for that therefore time delay have employed the lower mode of the availability of frequency spectrum for lowering, and the data packet transmission that follow-up a large amount of cycle is arrived, because network equipment has obtained information in traffic performance, therefore network equipment can carry out pre-scheduling to follow-up arrival data.

Above-mentioned available resources are time-domain resource or frequency domain resource or running time-frequency resource.

Wherein, receiving equipment can be the second subscriber equipment or network equipment.Be introduced respectively below.

Situation one, receiving equipment are network equipments.Specifically can see Fig. 3 A.

The network equipment of the embodiment of the present invention is except carrying out resource distribution for first user equipment as receiving equipment.

Concrete, network equipment determination first user equipment needs transmission Burst Period business; For described first user Equipments Setting is for transmitting the Secondary resource of follow-up data bag, wherein said follow-up data bag is the packet in the packet of Burst Period business except initial data packets.

In force, carrying out the network equipment of resource distribution and can be same network equipment as the network equipment of receiving equipment, also can be different network equipments.

Except Secondary resource, the network equipment of the embodiment of the present invention can also distribute first resource for first user equipment.

Concrete, the resource allocation information of described network equipment broadcast for distributing described first resource, or send resource allocation information when described first user equipment access community to described first user equipment.

Accordingly, the resource allocation information that described first user equipment is broadcasted according to network equipment or received when accessing community, determines described first resource.

For improving the level of resources utilization, whole first resource can be distributed to subscriber equipment used in system and share by the embodiment of the present invention, the benefit of this mode is when system business amount is lower, collision probability can control a lower level, when in system, traffic carrying capacity is higher, collision probability sharply increases, thus has a strong impact on reliability.

In force, all first resources all can be distributed to each subscriber equipment, each like this subscriber equipment can use whole first resource.

Preferably, in order to average out in collision probability and the level of resources utilization, simultaneously for different business subscriber equipment provides different Reliability Assurances, a kind of mode is that whole first resource Further Division is become some dedicated channels, by carrying out resource multiplex to several different user devices each dedicated channel allocation thus improving resource utilization.Simultaneously because the resource used between dedicated channel is mutually orthogonal, the subscriber equipment being therefore only assigned with same dedicated channel just likely collides (in such as Fig. 2 B, the initial data transfer of subscriber equipment 1 and subscriber equipment 2 just may collide).

Concrete, all first resources are divided into multiple dedicated signaling by described network equipment, and each special signal is distributed at least one subscriber equipment, and according to distribution condition determination resource allocation information.

Wherein, network equipment can for user equipment allocation be for carrying out the dedicated channel resource of initial data packets transmission and the transformation parameter for carrying out initial transmission after subscriber equipment access network.In addition network equipment can according to the difference of different user devices to reliability requirement, dedicated channel is distributed, be such as the dedicated channel (collision probability that collateral security is lower) that user equipment allocation users multiplexing number of devices that reliability requirement is higher is as far as possible few, a dedicated channel can also be distributed separately for the subscriber equipment that reliability requirement is higher; And the higher dedicated channel of users multiplexing number of devices (thus ensureing higher resource utilization) can be distributed for it for the subscriber equipment lower to reliability requirement.

For Secondary resource, network equipment can by pre-scheduling configuration information be described first user Equipments Setting for transmit Burst Period business packet in the Secondary resource of follow-up data bag except initial data packets;

Accordingly, described first user equipment, according to the pre-scheduling configuration information of the described network equipment received, determines described Secondary resource.

Based on the characteristic of Burst Period business, when network equipment unclear needs are user device configuration Secondary resource, thus one preferably mode be:

The traffic performance information of described Burst Period business is sent to described network equipment by described first user equipment, is described first user Equipments Setting pre-scheduling configuration information to make described network equipment according to described traffic performance information;

Accordingly, described network equipment is after receiving the traffic performance information from the Burst Period business of described first user equipment, determine that first user equipment needs transmission Burst Period business, and be Secondary resource described in described first user Equipments Setting according to described traffic performance information.

Wherein, the traffic performance information of described Burst Period business is sent to described network equipment by described first user equipment, comprising:

Described traffic performance information is sent to described network equipment by MACPDU (MediumAccessControlPacketDataUnit, media access control protocol data unit) by described first user equipment together with initial data packets; Or

Accordingly, described network equipment receives described traffic performance information by MACPDU.

Below to send to described network equipment to be described together with initial data packets described traffic performance information.

For cellular uplink transmission situation, when after first user device transmission layer after first packet of Burst Period business arrives, packet and business attribute information (shown in table 1) are packaged into protocol layer PDU (this patent is described for the packaged type of mac-layer protocol to business attribute information, but also do not get rid of business attribute information is encapsulated to the implementation then transferring to MAC layer to transmit by more upper-layer protocol) and send to network equipment by preempt-mode or dedicated channel mode by first user equipment.After network equipment successfully receives initial data packets by preempting resources or dedicated channel mode, forward wherein business datum on the one hand, be on the other hand that the transmission of follow-up data bag is carried out pre-scheduling and configured wherein pre-scheduling configuration information and comprise allocation of radio resources and (comprise the position of the time slot that Radio Resource takies according to the business attribute information of wherein carrying, bandwidth, carrier frequency, cycle, frequency-hopping mode etc.), and transformation parameter configuration (comprising modulation coding mode, multiple antennas configuration etc.).Here pre-scheduling refers to before the actual uplink data of first user equipment arrive, and network equipment will carry out allocation of radio resources that uplink distributes and transformation parameter configuration notification to the process of first user equipment in advance.

Network equipment by pre-scheduling information configuration to first user equipment and after first user equipment side comes into force, when first user equipment side follow-up data bag arrives, first user equipment directly uses the pre-assigned Radio Resource of network equipment to use pre-configured transformation parameter to carry out uplink according to the instruction of pre-scheduling information.Network equipment, according to pre-scheduling configuration information, on preallocated Radio Resource, adopts pre-configured transformation parameter to attempt receiving.Detailed process is see can see Figure 13.

Type of service	Data package size	The Packet Generation cycle	Duration
				Burst Period business	500bits	20ms	1s

Table 1 business attribute information example

After network equipment successfully receives the upstream data bag transmission from first user equipment, the far-end server be transmitted to by upstream data in core net processes.

After being assigned with Secondary resource, the embodiment of the present invention additionally provides scheme that is explicit or implicit expression two kinds release Secondary resource.

Implicit expression discharges:

Described first user equipment and network equipment set a business separately and continue timer, described first user equipment and network equipment business separately continue timer then after, discharge described Secondary resource.

Business is continued to the duration of timer, first user equipment is in advance by business duration informing network side apparatus, therefore network equipment can be first user equipment pre-scheduling resource settings effective time, and after exceeding effective time, carry out this locality release, the same pre-scheduling opening timing effective time device carried in first user equipment needs configure according to pre-scheduling, and after timer expiry, carry out the local release of pre-scheduling configuration.

Explicit release:

Described first user equipment, after determining to need to discharge described Secondary resource, discharges described Secondary resource, and notifies that described network equipment is released to the described Secondary resource of described user equipment allocation;

Accordingly, described network equipment receive described first user equipment need discharge Secondary resource notice after, discharge described Secondary resource.

In force, first user equipment can be determined to need the reason discharging described Secondary resource to have a lot, is such as sent completely with data, alarm event releasing etc.

Preferably, the release of above-mentioned implicit expression and explicit release also can together with use.

That is, can discharge with reference to timer, if because some reasons need to discharge in advance, then first user equipment can the release of informing network side apparatus.

Such as because such as alarm event removes the situation that the Burst Period transfer of data caused occurs to stop in advance before not reaching the duration for the main triggering reason of explicit pre-scheduling configuration release, first network side apparatus can by triggering the pre-scheduling configuration dispose procedure of display in this case, trigger network side apparatus discharges the Radio Resource that pre-scheduling configuration distributes in advance, reaches the object avoiding waste of radio resources.

In force, network equipment, after the packet receiving Burst Period business, needs Packet Generation to server.

Row give some instances and to be described in detail to the solution of the present invention below.

Wherein the receiving terminal of one and two is base station; The receiving terminal of three and four is subscriber equipment.

One, as shown in figure 13, the distribution of the embodiment of the present invention 12 ascending resource comprises with the method for transmission:

Step 1: after initial data packets arrives, subscriber equipment directly carries out uplink by first resource.

Preferably, in the PDU of MAC layer, initial transmitted data packet and service feature information is carried.

Wherein, service feature information can include but not limited to: the information such as size, cycle, duration of message bag.

In force, first resource can be base station is user equipment allocation in advance, and system broadcasts mode can be passed through in such as base station, and instruction current area can be used for the up information seizing transmission; Also can access in this community process for the first time at subscriber equipment, be user equipment allocation dedicated transmissions resource.Except base station is allocated in advance, first resource can also specify in the protocol.

Initial uplink transmission MAC layer PDU forms schematic diagram can see Figure 14, it should be noted that the main purpose of this schematic diagram is to illustrate that this MACPDU needs the key message item carried and the object of carrying these items of information, comprising MAC layer packet header form in practical implementations and the order of each item of information in MACPDU can change as required.

Carry out initial uplink transmission for based on preempt-mode, due to the id information of the uplink transmission resource associated user equipment that base station cannot adopt according to subscriber equipment, therefore subscriber equipment needs to carry self-ID information when carrying out uplink.In addition because business datum and control information are concentrated in original position and the length therefore being indicated control information and business information in a MACPDU by MAC header.Preferably, for ensureing that initial transmission can not be tampered, can also in the integrity check information finally comprised for current PDU of MACPDU.

Step 2: the information that base station is relevant according to the service attribute obtained from initial transmission (comprises traffic type information, the size of packet, Packet Generation cycle and duration), and in conjunction with initial data packets due in, for pre-scheduling configuration is carried out in the transmission of follow-up data bag.

Wherein, pre-scheduling configuration information comprises allocation of radio resources and transformation parameter configuration, and (allocation of radio resources comprises the position of the time slot that Radio Resource takies, bandwidth, carrier frequency, cycle, frequency-hopping mode etc., transformation parameter configuration comprises modulation coding mode, multiple antennas configuration etc.)

Carrying out uplink pre-scheduling information is sent to subscriber equipment by dedicated control signaling mode by base station.

In addition pre-scheduling can also be configured effective time announcement subscriber equipment by base station, and after pre-scheduling configuration time-out effective time, subscriber equipment needs implicit expression to discharge pre-scheduling configuration.

Step 2a: after base station correctly receives initial uplink transfer of data from subscriber equipment, can obtain destination server address according to the subscriber equipment ID preserved in advance and destination server address mapping relations; Also according to the destination address of carrying initial transmitted data packet itself, can determine destination server address, base station, according to destination address, will receive initial uplink packet is transmitted to destination server.

Step 3: after subscriber equipment successfully obtains pre-scheduling configuration, trigger pre-scheduling configuration take-effective, and configured message informing base station pre-scheduling configuration by carrying out uplink pre-scheduling and come into force in user equipment side, if carry pre-scheduling in pre-scheduling configuration information to configure effective temporal information, then subscriber equipment is opened pre-scheduling and is configured effective time timer.

Step 4: after follow-up data bag arrives, configured by pre-scheduling, subscriber equipment carries out the transmission of upstream data bag.

Wherein, the MACPDU group packet mode for the uplink based on scheduling mode can see existing LTE system mac-layer protocol.

Base station side, according to pre-scheduling configuration information, on preallocated Radio Resource, adopts pre-configured transformation parameter to attempt receiving.

Step 4a: after base station correctly receives subsequent upstream transfer of data from subscriber equipment, can obtain destination server address according to the subscriber equipment ID preserved in advance and destination server address mapping relations; Also according to the destination address of carrying initial transmitted data packet itself, can determine destination server address, base station, according to destination address, will receive subsequent upstream packet is transmitted to destination server.

Two, as shown in figure 15, in the embodiment of the present invention 14 explicit carrying out uplink pre-scheduling configuration release flow process, subscriber equipment finds Burst Period business premature termination (such as operation layer alarm is removed), at this moment can by carrying out uplink pre-scheduling resource allocation explicit dispose procedure trigger base station release preassignment ascending wireless resource.

Step 1: subscriber equipment determines to discharge Secondary resource in advance, sends carrying out uplink pre-scheduling configuration release Indication message to base station.

Step 2: base station is released to the preallocated Secondary resource of current user equipment, and completes message by up preassignment and will successfully discharge result notifying user equipment after receiving pre-scheduling configuration release instruction from subscriber equipment.

Step 3: subscriber equipment release Secondary resource.

Wherein, step 3 also can perform together with step 1.

Three, as shown in figure 16, the embodiment of the present invention 15 honeycomb D2D and scheduling configure and comprise with the method for transmission:

Step 1: after initial data packets arrives, subscriber equipment directly carries out D2D by first resource directly to be transmitted.

Wherein, subscriber equipment carries initial transmitted data packet in MAC layer PDU.

Initial D2D transmits MAC layer PDU and forms schematic diagram as shown in figure 17, it should be noted that the main purpose of this schematic diagram is to illustrate that this MACPDU needs the key message item carried and the object of carrying these items of information, comprising MAC layer packet header form in practical implementations and the order of each item of information in MACPDU can change as required.

Initial data packets D2D is directly transmitted, because D2D communication receiver does not obtain the relevant information of scheduling in advance, therefore receive transmission subscriber equipment ID that subscriber equipment needs to carry according to MAC and receive subscriber equipment ID, judging that current initial data packets is reported and submitted and whether should receive and submit high level to.

Preferably, for ensureing that initial transmission can not be tampered, can also in the integrity check information finally comprised for current PDU of MACPDU.

Step 2: send subscriber equipment and send D2D pre-scheduling configuration request message to base station, and carry business attribute information in pre-scheduling request message.

Step 3: the information that base station is relevant according to the service attribute obtained from initial transmission (comprises traffic type information, the size of packet, Packet Generation cycle and duration), and in conjunction with initial data packets due in, for pre-scheduling configuration is carried out in the transmission of follow-up data bag.

In addition D2D pre-scheduling can be configured effective time announcement subscriber equipment by base station, and after pre-scheduling configuration time-out effective time, sending subscriber equipment needs implicit expression to discharge pre-scheduling configuration.

Step 4:D2D sends after subscriber equipment successfully obtains D2D pre-scheduling configuration, triggers D2D pre-scheduling configuration take-effective, and configure the D2D pre-scheduling of message informing base station by D2D pre-scheduling and configure and come into force in user equipment side.

If carry D2D pre-scheduling in D2D pre-scheduling configuration information to configure effective temporal information, then subscriber equipment is opened pre-scheduling and is configured effective time timer.

Step 5: before follow-up data bag arrives, D2D sends subscriber equipment and dispatches Indication message by pre-scheduling message notice D2D reception subscriber equipment by D2D.

Step 6: after follow-up data bag arrives, D2D transmission subscriber equipment carries out D2D according to pre-scheduling configuration and directly sends, and D2D reception subscriber equipment attempts reception according to the pre-scheduling configuration information obtained in advance from D2D transmission subscriber equipment.

The D2D scheduling indication information that in Figure 16, D2D transmission subscriber equipment sends is the 2nd D2D scheduling indication information for the multiple packet of schedule subsequent; The mode that the D2D sent for dispatching a packet dispatches indication information and transmission the 2nd D2D dispatches indication information is similar, when difference is only to need to send follow-up data bag at every turn, all need mode first D2D to dispatch indication information, do not repeat them here.

Four, as shown in figure 18, in the embodiment of the present invention 17 honeycomb D2D pre-scheduling configuration release schematic flow sheet, under user apparatus service finds Burst Period business premature termination situation, D2D directly transmits (such as operation layer alarm is removed), can transmit preassignment uplink transmission resource by honeycomb D2D pre-scheduling resource allocation dispose procedure trigger base station release D2D.

Step 1:D2D sends D2D pre-scheduling assignment configuration and discharges Indication message to base station after sending the subscriber equipment decision preallocated D2D scheduling in release base station in advance configuration.

Step 2: base station is released to the preallocated D2D transfer resource of present terminal after receiving the pre-scheduling configuration release instruction of D2D transmission subscriber equipment, and complete message informing D2D transmission subscriber equipment by successfully discharging result by D2D preassignment.

Step 3:D2D sends subscriber equipment release Secondary resource.

Wherein, step 3 also can perform together with step 1.

It can be seen from the above: embodiment of the present invention subscriber equipment sends the initial data packets of Burst Period business to receiving terminal by first resource, wherein said first resource is based on seizing or the pre-assigned resource based on dedicated channel; After sending described initial data packets by described first resource to receiving terminal, sent the follow-up data bag of described Burst Period business by Secondary resource to receiving terminal, wherein said Secondary resource is the common transmission resource based on scheduling.To seize due to the employing of Burst Period business first arrival bag or pre-assigned private resource transmits, no longer need being transmitting uplink data scheduling of upstream transmissions resource by random access procedure trigger base station, and for the transmission of follow-up data bag, the embodiment of the present invention is transmitted in common transmission resource, do not need under traditional approach, after each follow-up data bag arrives, subscriber equipment all needs to carry out Stochastic accessing, thus shortens the wait time delay of whole Burst Period business process of transmitting; Further shortening Burst Period real-time messages, in the wait time delay of MAC layer, can better meet such as alarm class message to the requirement transmitting real-time and reliability.
