Embodiment
Herein the preferred embodiments of the present invention are described below with reference to the accompanying drawings.In the following description, do not describe well-known function or structure in detail, this is because they will make the present invention obscure with unnecessary details.
The invention relates under the situation that three kinds or more services are provided in wireless packet data communication system, to signaling traffic and non-signaling traffic carry out multiplexed.According to the present invention, the head of PDU comprises and is used to the service ID field supporting the length field of variable-length and be used for identification service, is adapted to various service scenario thus.
To in the CDMA2000 system, especially in environment, the preferred embodiments of the present invention be described below by the proposed CDMA2000 1xEV-DV of 3GPP2 (third generation partner program 2).Yet, be clear that for those skilled in the art based on similar techniques and channel architecture, the present invention may be used on any other mobile communication system.
Fig. 1 has illustrated in the present invention and has been applied to layered protocol architecture structure in this OSI Reference Model of CDMA2000 system.The CDMA2000 system be used in reference to CDMA2000 1x system and CDMA2000 1xEV-DV system the two.The term of Shi Yonging " layer " is meant the software or the hardware of the function of being responsible for the execution equivalent layer herein.
Referring to Fig. 1, the CDMA2000 system comprises top signaling (upper signaling) layer 10, data service layer 11 and voice service layer 12, and they arrive layer 7 corresponding to osi layer 3.The CDMA2000 system also is included in LAC (link-access control) layer 13, RLP layer 14 and the MAC layer 15 in the osi layer 2, and the PHY in osi layer 1 (physics) layer 16.
Typically, the CDMA2000 system will directly be wirelessly connected to the function of BS of MS and those functions of base station controller (BSC) are separated by layer.That is to say that BS is responsible for the function of layer 1, and BSC is responsible for the function of layer 2 to layer 7.
The head of LAC layer 13 by will be relevant with checking, sequencing and addressing, the report field relevant with radio link quality, and length field appends to from the signaling information that top signaling layer 10 generates, and creates control messages.LAC layer 13 is segmented into this control messages MAC layer 15 transmissible size then, and the message of the beginning of Indication message or continuation is begun (SOM) position adds each section to, produces data cell thus.
RLP layer 14 be by will being segmented into the transmissible size of PHY layer 16a from the data flow that data service layer 11 generates, and with sequence number these sections will be numbered, and create data cell.In addition, in the control information of the data, services that RLP layer 14 carries out, generate data cell from relevant RLP.
Be called SDU (service data declaration form unit) by LAC layer 13 and RLP layer 14 both data cell of generation.Feature according to SDU is categorized as signaling traffic or non-signaling traffic with SDU.Signaling traffic is the signaling message from LAC layer 13, and non-signaling traffic is service data or control information from RLP layer 14.Non-signaling traffic is further divided into main business and secondary service according to its COS.
The physical channel of packet data service that is used for PHY layer 16 is as follows.
FCH: carry low rate traffic data and control information as the existing FCH of IS-95;
SCH: main low rate traffic data of carrying as the existing SCH of IS-95; And
PDCH: stably carry business datum at a high speed.
Fig. 2 has illustrated the form of the MuxPDU type in the cdma system.Full rate (1 times of speed) is that 9600bps, 1/2 speed are that 4800bps, 1/4 speed are that 2400bps and 1/8 speed are 1200bps.Data rate is determined the size of physical channel frame.
Referring to Fig. 2, the MuxPDU Class1 is uploaded to deliver letters at the physical channel of supporting 1200 to 9600bps and is made information, main business and secondary service.MuxPDU type 2 is supported the data rate of the highest 14400bps, is used to be similar to the use of MuxPDU Class1.The two all is used for communicating control information and business datum on FCH and DCCH MuxPDU Class1 and MuxPDU type 2.Main business and secondary service are service datas, perhaps from the RLP control information of RLP layer, its with distinguish to some extent from the signaling information top Signaling Layer, that be used to call out control.COS according to control information or data is separated main and secondary service.
MuxPDU type 3 sends business datum from the RLP layer with the speed that is equal to or less than 14400bps on SCH.MuxPDU type 4 transmits specific (lacking relatively) control messages on FCH.
According to the size of signaling information or RLP control information, determine the size of the pay(useful) load in the MuxPDU Class1,2,3 and 4 regularly.Receiver can detect the size of pay(useful) load from the PDU that received, especially its head.On the other hand, the PDCH that is advised for CDMA2000 1xEV-DV system only supports to have the MuxPDU type 5 of the field of indication pay(useful) load length, with support variable data rate.
MuxPDU type 5 is used for sending the business datum from the RLP layer on PDCH.The PDU of MuxPDU type 5 comprises the field of indication pay(useful) load length.
Fig. 3 understands the structure of the PDU of MuxPDU type 5 in detail.
Referring to Fig. 3, the PDU of MuxPDU type 5 comprises the head with 6,14 or 22 bit lengths, 0 or 10 extension header, and pay(useful) load.
Head comprises 3 SR_ID (service reference identifier), 1 expansion designator, 2 bit length designator and the length (LEN) with 0,8 or 16.Expansion designator indication extension header subsequently exists or does not exist.Length indicator indication LEN subsequently exists or does not exist, and if the LEN existence, this LEN is then described.LEN is 8 or 16, is the length of unit representation pay(useful) load with the byte.Therefore, the head length of MuxPDU type 5 is 6,14 (comprising 8 LEN) or 22 (comprising 16 LEN).
About the implication of SR_ID, " 000 " indication signaling, " 001 " to " 110 " indicate service index and " 111 " to indicate invalid service.Service index sign connects the COS that keeps by individual call.When length indicator was " 00 ", it meant LEN and does not exist.If it is " 01 ", then LEN is 8, if it is 10, then LEN is 16, and if it be " 11 ", then pay(useful) load has regular length.
Whether length indicator indication LEN subsequently exists, and if LEN exist, this LEN is then described.LEN is the length that unit provides pay(useful) load with the byte.Have only when the expansion designator is 1, extension header just exists.Extension header is used to expand the use of the PDU of MuxPDU type 5.
If extension header is " 01 ", then it comprises the MuxPDU size of 2 encapsulation MuxPDU types, 2 encapsulation and is 4 of byte align reservation.The MuxPDU size and the reservation position of encapsulation MuxPDU type, encapsulation are called as encapsulation header together.
Encapsulation MuxPDU type is indicated the MuxPDU type of pay(useful) load subsequently.For the implication of encapsulation MuxPDU type, it is retention that MuxPDU type 4 and " 00 " are indicated in " 01 " indication MuxPDU Class1, " 10 " indication MuxPDU type 2, " 11 ".
The MuxPDU size of encapsulation is the size of the service unit in the FCH indication pay(useful) load of supporting full rate, 1/2 speed, 1/4 speed and 1/8 speed.That is to say " 00 " indication full rate, " 01 " indication 1/2 speed, " 10 " indication 1/4 speed, and " 11 " indication 1/8 speed.For example, when the FCH that is full rate 9.6kbps generated the service unit of MuxPDU Class1, the size of service unit was 168.
If on FCH or DCCH, transmit data, then use MuxPDU Class1,2 or 4.MuxPDU type 4 is carried short relatively data in the short time of 5ms on FCH or DCCH.In MuxPDU type 4, only form PDU, and need not carry out multiplexed with a SDU.MuxPDU Class1 and MuxPDU type 2 allow signaling traffics and maximum two non-signaling traffics (main and secondary service) in a PDU by multiplexed.
Fig. 4 has illustrated the multichannel multiplexing method that is used for MuxPDU Class1 and MuxPDU type 2.
Referring to Fig. 4, have the MuxPDU Class1 that multiplexed option is set to " 0x1 " and defined 12 kinds of multichannel multiplexing methods.For example, for full rate, 40 main businesses of head " 1101 " indication and 128 precedences are wanted professional combination.MuxPDU type 2 with the multiplexed option that is set to " 0x2 " has defined 25 kinds of multichannel multiplexing methods.For example, for 1/2 speed, 20 main businesses of head " 1100 " indication and 101 precedences are wanted professional combination.
Therefore, according to predetermined multiplexed rule multiplexed different business in a PDU, and the information of relevant multiplexed rule is written in the head of PDU.Yet because the size of data that presets, this multichannel multiplexing method has reduced multiplexed efficient.Will be in order to improve by the maximum number of multiplexed available service type, with the size of head bring up to the number of the available combination of type of service as many.
The present invention adopts the MuxPDU type 7 of supporting variable-length, to carry out multiplexed to the SDU with various features effectively.
Fig. 5 has illustrated the structure according to the PDU of the MuxPDU type 7 of the embodiment of the invention.
Referring to Fig. 5, the PDU of MuxPDU type 7 comprises head and pay(useful) load.Pay(useful) load comprises the part of signaling traffic or non-signaling traffic at least.The head of MuxPDU type 7 comprises existence or the non-existent 1 bit length designator and 0 or 4 bit lengths (Length) of 3 SR_ID (service reference identifier), indicating length.
Compare the professional non-signaling traffic different of the SR_ID distinguishing signaling of MuxPDU type 7 with six kinds with the SR_ID of MuxPDU type 5.The value of the SR_ID of MuxPDU type 7 is described below with reference to Fig. 6.
Referring to Fig. 6, SR_ID identifies signaling traffic by " 000 ", and arrives six kinds of different non-signaling traffics of " 110 " sign by " 001 ".If SR_ID is " 111 ", then not service of its indication, meaning MuxPDU is complete (full).As mentioned above, SR_ID " 001 " arrives " 110 " sign connects maintenance by individual call packet data service.
Length indicator is to indicate 1 mark whether length field is arranged subsequently.Have only when length indicator is " 1 ", this length is included in MuxPDU type 7 heads.Head is 0 or 4 bit fields, and it is the size of unit representation pay(useful) load with the eight bit byte.The length of pay(useful) load is than big 2 eight bit bytes of this length value.Therefore, pay(useful) load length is set to (length+2).Because pay(useful) load length represents with eight bit byte, so if used 4 bit length field, then can be by 4 bit representations 0 to 15.As mentioned above because pay(useful) load length is " length+2 ", then its can be set to the highest 17 bytes (=15+2), i.e. 136 (=17 * 8).
If length indicator is " 0 ", then ignore this length.Therefore, head is 4 and thinks that pay(useful) load occupies remaining physical frame.Fig. 7 has illustrated according to embodiments of the invention, has had the form of the example MuxPDU type 7 physical channel frames of six non-signaling traffics and a signaling traffic.Except that the CRC cyclic redundancy code that is used for error correction), length (Length) is 4, and the size of PDU that is used for 20 milliseconds of FCH frames of 9.6kbps is 172.
Referring to Fig. 7,172 PDU have multiplexed therein six non-signaling traffics and a signaling traffic.Six non-signaling traffics have respectively and are set to the SR_ID that " 001 " arrives " 110 ", and non-signaling traffic has the SR_ID that is set to " 000 ".
According to the multiplexed option information that between MS and BS, exchanges during being provided with in service, be provided for the MuxPDU type of physical channel.Multiplexed option information is the value of indicating MuxPDU type, PDU size and being used for the set (rate set) of the data rate of respective service.During service was provided with, MS and the relevant information that presets multiplexed option of BS exchange were with the MuxPDU type of determining thus to use in communication period.In order to use MuxPDU Class1 or MuxPDU type 2 in communication period, MS and multiplexed option of BS exchange " 0x01 " (rate set 1) or the multiplexed option of " 0x02 " (rate set 2).Be preferably,, between MuxPDU type 7 and existing other MuxPDU type, obscure so that avoid for the multiplexed option that MuxPDU type 7 of the present invention is provided with greater than " 0x10 ".The structure of a plurality of options that are used for MuxPDU type 7 is described below with reference to Fig. 8 and 9.
Fig. 8 has illustrated according to embodiments of the invention, according to the rule of its setting greater than the multiplexed option of " 0x10 ".
Referring to Fig. 8, from the highest significant position (MSB) of the multiplexed option that is used for MuxPDU type 7,3 Format_Descriptor (format descriptor) have described the form of multiplexed option.It only is set to indicate " 000 " of form 1.That is to say, the concrete form that this multiplexed option and other multiplexed option are distinguished is not set in addition, but using form 1 only.
MuxPDU_Type (MuxPDU type) be 3 long, with from the MuxPDU Class1 to MuxPDU type 6, identify MuxPDU type 7.Therefore, 3 MuxPDU_Type is set to indicate " 100 " of MuxPDU type 7.
2 following bit fields, Data_Block_Size (data block size) is set to " 11 ", the indication variable-length, this is because MuxPDU type 7 has variable-length.6 Max_Data_Blocks (maximum data piece) is set to indicate aspect the number of piece hard-core " 000000 ", and perhaps " 000001 " arrives one of " 001000 "." 000001 " means and only comprise a piece in PDU, and " 001000 " means comprise eight pieces in PDU.Two least significant bits (LSB:Rate_Set (rate set)) indicated speed collection.For rate set 1 (9.6kbps series) is provided with " 01 ", and be that rate set 2 (14.4kbps series) is provided with " 10 ".Therefore, final available multiplexed option is 0x1301,0x1302,0x1305 and 0x1306.Because as Rate_Set and Max_Data_Blocks, each has two variable values, becomes available so always have four multiplexed options.
Fig. 9 understands the structure of multiplexed option 0x1301 and 0x1302 in detail in the middle of final available multiplexed option 0x1301,0x1302,0x1305 and 0x1306.
Multiplexed option 0x1301 will be described." 1301 " are hexadecimal number, and it is equal to binary number " 1001100000001 "." 000 " is added to generation " 0001001100000001 " in this binary number.
Referring to Fig. 9, multiplexed option 0x1301 comprises: be set to " 000 " Format_Descriptor as MSB, be set to the MuxPDU_Type of " 100 ", be set to the Data_Block_Size of " 11 ", be set to the Max_Data_Blocks of the maximum number of the MuxPDU among " 000000 ", the indication physics SDU, and the Rate_Set that is set to " 01 ".Multiplexed option 0x1301 has the Rate_Set of " 01 " that is set to indicated speed collection 1 (9.6kbps series).
With reference to Figure 10, use description between MS and BS, set up the operation of calling out and consulting physical channel and multiplexed option.Though at length illustrate and described and set up physical channel and message name and the flow process that multiplexed option is associated is set, obviously depend on employed system, system configuration or operation intention, can change these details.
Referring to Figure 10, when the business of going to MS when network arrives BS, BS transmits general page message and arrives MS in step (a), be used for the calling of packet data service with foundation.At step (b), MS tells BS whether it accepts this calling and which channel it supports by page-response message.MS supports PDCH and the Common Power Control Channel (CPCCH) on the forward link (FL), and FCH or DCCH on the reverse link (RL).
At step (c), FL and RL channel allocation information are sent to MS by extended channel assignment message (ECAM).MS and BS obtain the channel that is distributed in step (d).
At step (e), MS finishes message by Exchange Service request message, service connection message with serving to be connected with BS, and the information of the relevant service that will provide is set.In above-mentioned message, MS or BS are provided with service configuration record (SCR), and it provides the size and radio configuration (RC) information of the needed multiplexed option of supply service, physical channel, physical channel frame.BS or MS be by analyzing SCR, determines whether to support this service as disposing in this SCR, and if can support this service, then the service of transmitting connects and finishes message to MS or BS.
In step (f), MS and BS set up RLP and PPP (point-to-point protocol) synchronously and exchange subscriber business according to SCR.
The multiplexed option that disposes MuxPDU type 7 although it is so is not so that identical with other MuxPDU type in the foregoing description, but as another embodiment, also consider to pass through with basic multiplexed option, be MuxPDU Class1 and MuxPDU type 2, mix with MuxPDU type 7 to create the MuxPDU type of mixed mode.The MuxPDU type of mixed mode will be described with reference to figure 11A and 11B.
Figure 11 A has illustrated the form according to the mixed mode MuxPDU Class1 of another embodiment of the present invention, and Figure 11 B has illustrated the form according to the mixed mode MuxPDU type 2 of second embodiment of the invention.
Referring to Figure 11 A, mixed mode MuxPDU Class1 has defined 12 kinds of multichannel multiplexing methods.Three kinds of COS are available: main business, signaling traffic and MuxPDU type 7.In a PDU, transmit these three kinds of services.The head of mixed mode MuxPDU Class1 comprises mixed mode (MM), type of service (TT) and business model (TM).For example, if be " 1 ", TT for " 1 " and TM are " 01 " for full rate (9600bps) MM, then main business is that 40 and MuxPDU type 7 are 128.According to this setting, MS is composite service in a PDU, so that transmit.
When full rate, use FCH and DCCH.When 1/2 speed (4800bps), 1/4 speed (2400/2700bps) and 1/8 speed (1200/1500bps), only use FCH and do not use DCCH, and 80,40 and 16 main businesses are only arranged respectively is available.
Referring to Figure 11 B, mixed mode MuxPDU type 2 has defined 17 kinds of multichannel multiplexing methods.As mixed mode MuxPDU Class1, three kinds of COS are available: main business, signaling traffic and MuxPDU type 7.The head of mixed mode MuxPDU type 2 comprises MM and frame pattern (FM).For example, if be that " 1 " and FM are " 0110 " for full rate (14400bps) MM, then main business is 20, and MuxPDU type 7 is 242.According to this setting, MS is composite service in a PDU, so that transmit.
When full rate, use FCH and DCCH.When 1/2 speed (7200bps), 1/4 speed (3600/2700bps) and 1/8 speed (1800bps), only use FCH and do not use DCCH.If for 1/2 speed (7200bps) MM is that " 1 " and FM are " 001 ", then main business is 20, and signaling traffic is 101.If for 1/4 speed (3600bps) MM is that " 1 " and FM are " 00 ", then main business is 20, and signaling traffic is 32.According to this setting, MS is composite service in a PDU, so that transmit.
MS and BS use mixed mode MuxPDU Class1 and mixed mode MuxPDU type 2 to set up and call out and consult physical channel and multiplexed option with the described same way as of reference Figure 10.With mixed mode MuxPDU Class1 and mixed mode MuxPDU type 2 somethings relevant, that will note be, MS and BS must decide through consultation mixed mode MuxPDU Class1 and mixed mode MuxPDU type 2 when service is provided with, to use this mixed mode MuxPDU Class1 and mixed mode MuxPDU type 2.
