Most preferred embodiment describes in detail
Now, more fully introduce the present invention, preferred embodiment of the present invention shown in the drawings with reference to accompanying drawing.But, the present invention can many different forms realize, should not be limited to listed example; Also have, it is for a more complete understanding of the present invention that these examples are provided, and for the present technique professional, these examples can be expressed scope of the present invention fully.Similar sign is represented similar element.
Professional person of the present invention can recognize that the present invention can be with method, and the form of system's (equipment) or computer program realizes.Accordingly, the present invention can adopt pure hardware, and the form of pure software or software and hardware combining realizes.
Following to the accompanying drawing detailed introduction of (comprising block diagram and flow chart) in, illustration various aspects of the present invention.Should be appreciated that, each piece, and the combination of piece all can be realized by computer program instructions.These computer program instructions can be provided for a processor or other programmable data processing unit, to produce a mechanism, thereby the instruction of carrying out on processor or other programmable data processing unit can generate the method for the function that is used to carry out physical block.These computer program instructions also can be stored in the computer-readable memory, but its instruction processorunit or other programmable data processing unit are with ad hoc fashion work, therefore, be stored in instruction in the computer-readable memory generate a kind of comprise can realization flow figure in or the product of the command device of specified function in the piece.
Accordingly, the combination of the device of appointed function is carried out in the piece support of being given an example, the program command of the combination of the step of execution appointed function and execution appointed function.The combination that is appreciated that each piece of being given an example and piece can be realized by the hardware based computer system that earmarks of carrying out appointed function or step, or be realized by the hardware of appointed function and the combination of computer instruction.
The present invention can provide application programming interfaces (API), of utilizing that UDP carries of voice, data or the multimedia application that this interface allows to carry out on terminal equipment based on the interface of port from portable terminal to extended wireless access network application program (ERANAP) designated key parameter.This parameter can comprise one from mobile radio station, the service quality indication of being determined by the voice of carrying out on the terminal equipment, data or multimedia application.This service specified quality can comprise a time-delay susceptibility, and an error rate will be by one of channel and/or other parameter coordination desired sound quality.This service quality standard can be utilized the R datum mark in (for example) EGPRs mobile radio station through a ppp link from the terminal equipment to the portable terminal, is sent to portable terminal from terminal equipment.This just allows with very big flexibility specified quality of service.
For example, the delay requirement of Real-Time IP business is generally with the application program of being visited or professional difference and difference.The voice delay requirement is generally relatively stricter.Concrete, unidirectional end end time-delay generally should be the 100ms level.Therefore, the 40ms or littler preferably of the time-delay on the Radio Link.On the contrary, a video flowing generally has looser delay requirement, and a low rate videoconferencing can keep the time-delay of 200-500ms on the one way link.The voice flow relevant with video conference can have similar time-delay.For video flowing and audio stream, frame error rate (FER) requires generally similar, that is, and and about 1%FER.
Collaboration application such as blank and dialogue generally is similar to video flowing, approximately 300-500ms.Generally, the way flow of the last media content of WWW the limited delay requirement that memory applied, does not have the delay requirement of appointment in those replica buffer by the point of destination.But, frame error rate requires still to wish for about 1%.Other application program can have the similar or low frame error rate that requires.But, for the application program of appointment, may need lower frame error rate.
The present invention comes from such common recognition, that is, GPRS network and other network are not generally known the application program moved on the terminal equipment.But, the application program of moving on portable terminal and the terminal equipment is closely related.Therefore, the present invention allows portable terminal according to the voice that move on the terminal equipment, data processing or multimedia application, for mobile radio station is specified a service quality, when specifying this service quality, preferably is independent of the performance characteristic of packet wireless communication network.Can come the specified services quality by direct appointment time-delay susceptibility and/or error rate.Perhaps, can come the specified services quality by transmitting the type of application of carrying out on the terminal equipment (for example, multimedia application, video conference or a voice telephony application program) to Radio Access Network.Also can use other to be used to specify the routine techniques of service quality.
A kind of recommended technology that is used for specified quality of service allows an application program of carrying out on terminal equipment Radio Access Network to be done the requirement of appointment.Like this, for example, terminal equipment just can be selected an interleave depth according to the application program of carrying out on it.In an example, can distribute one 4 bit code for staggered option available on the various GPRS network.Table 1 has been listed 4 possible bit code groups, is used to specify interleave depth and selects.
Table 1
| Code | Staggered |
| 0000 | Do not have staggered |
| 0001 | Piece on the 20ms is staggered |
| 0010 | Piece on the 40ms is staggered |
| 0011 | Diagonal angle on the 40ms is staggered |
| 0100 | Piece on the 60ms is staggered |
| ... | ... |
| 1000 | Use after waiting until |
| 1111 | Use after waiting until |
| ... | ... |
Therefore, terminal equipment can be selected a code according to the application program of operation on it, represents the interleave depth of an expectation to select.Similarly, terminal equipment is selected a specific encoding scheme by specifying 4 code points according to the application program of operation on it.Table 2 is for example understood the example of 4 codes, is used to specify encoding scheme.
Table 2
| Code | Encoding scheme |
| 0000 | There is not coding |
| 0001 | Conventional EGPRS discharges 99 incremental redundancies to reach better effect |
| 0010 | Real-time carrier in the link adaptation coding that circles round |
| 0100 | Cross over the pay(useful) load Turbo-coding of 40ms |
| 0101 | Cross over the pay(useful) load Turbo-coding of 100ms |
| 1000 | Use after waiting until |
| ... | ... |
| 1111 | Use after waiting until |
| ... | ... |
For the present technique professional person, the Turbo-coding is known.Description to it sees (for example): Near Shannon Limit Error-Correcting Coding andDecoding:Turbo-Codes (I) by Berrou, et al., IEEE, International Communications Conference, 1993.
The present invention can be used for an EGPRS Radio Access Network (ERAN).Fig. 4 for example understands the general structure of an ERAN.As shown in Figure 4, the EGPRS functional entity comprises following three function fructifications: wireless network control functional block (RNCF), radio network netgate (RNGW) and base station transceiver (BTS).Defined being equal among the function of base station transceiver and the GSM 03.06.ERAN can support real-time IP-based application program.The IuPs interface comprises two planes: user plane, be designated as IuPs '-u, and control plane, be designated as IuPs '-c.User plane interface is between enhancement service GPRS Support Node (E-SGSN) and RNGW.The control plane interface is between E-SGSN and RNCF.
Fig. 5 is the calcspar of an ERAN reference configuration.The ERAN reference configuration can be separated into independently parts fully with core network and Radio Access Network.The ERAN reference configuration also can be all access networks (for example, ERAN and UMT terrestrial access network (UTRAN)) a public packet switching code network based on GPRS is provided.
Fig. 6 for example understands the user-plane protocol of an EGPRS system.R99 is only different in the MAC layer with the R2000RLC/MAC layer.Non-independent convergence protocol of sub-network (SNDCP) and logic link control (LLC) layer can be counted as the sublayer of Release 99 link layers.Radio resource management entity is public for shown each user plane storehouse.Therefore, Radio Resource can extract from a public pond.Shown all link layers can be managed by a common link layer management entity (LLME), the professional access point identifier (NSAPI) of the network layer that its interface towards higher level protocol can be a dynamic assignment, its interface towards lower-level protocols is a link layer SAPI and temporary logical link body (TLLI).
Best Effort-Logical Link Control (BE-LLC) layer has reduced the link layer overhead of optimum efficiency business, and can provide optional agreement and data compression for the IP datagram transmission of the unknown.For the stream that is limited at single time slot operations, BE-LLC layer preferably transparent (after header compression) on user plane.Can add smallest total cost to allow the multi-slot operation.Logical link control layer (RT-LLC) allows IP/UDP or the IP/UDP/RTP data of transmission through the agreement compression in real time.This layer can utilize end end IP to connect and transmit stream in real time.An optional single time slot also can be provided, and after header compression, this time slot has the transparency at user plane.
Best voice transmission (OVE/OVG) option on the best voice transmission/GSM carrying circuit on the EGPRS allows to utilize EGPRS or GSM to carry the transmission that circuit comes the many speed of optimization adaptability (AMR) voice.The transmission that these carriers can be the low rate voice provides a single time slot temporary flow identity symbol (TFI).
Fig. 7 for example understands by the present invention, the terminal equipment of a mobile radio station and the protocol stack of portable terminal.As shown in the figure, voice, data or multimedia application are respectively 510,520 and 530, carry out an application layer on the UDP of terminal equipment layer 540.Voice, data or multimedia application respectively with quality of service application 550 interfaces, application program 550 is preferably also carried out an application layer on UDP layer 540.Quality of service application 550 and target resource agency (ORB) 560 interfaces, target resource agency (ORB) 560 operate in an application layer on the UDP layer 570 of portable terminal.Target resource agency and EGPRS Radio Access Network application program part (ERANAP) 580 interfaces.Therefore, application program 510,520 and 530 can utilize ORB 560 to consult concrete requirement.Utilize an interface based on port, application program goes up the ERANAP of operation with the FER and/or the delay requirement notice MT of flow process.ERANAP can be converted into this requirement clear and definite request, and starts the consultative process again of a related communication channel.
For example, if an application program has the transmission granularity of 20ms, and can stand on the wireless network time-delay, and not have tangible mass loss up to 100ms, then can transmit a request to ERAN, request is gone up the staggered data division in diagonal angle at 4-5 protocol Data Unit (PDU).Wireless network control module (RNCF) can change the characteristic of the staggered time-delay of 100ms.Other users' agreement can be in this continuous transmission course, before discharging a channel, one section time-delay to be arranged.
Perhaps, ORB 560 can be used to consult performance requirement.For example, may need 0.1% data packet error rate.Application program 510-530 can be by a quality of service application 550 with ORB 50 negotiated channel coding and staggered, so that desired performance to be provided.
Different prices is corresponding to different service quality, and the service quality that is provided causes corresponding charge.Accordingly, can provide the negotiation of this specific radio access carrier of customize services quality can cause the change of flow process charging process, it has reflected the use to Radio Resource.The technology that realizes this charge is to calculate the expense of a bag of transmission: c by following formula
p=B
cμ
r+ V
r, here, Bc is the basic expense of transmission, μ
rBe unique for this a flow services quality multiplier, when Vr is to use Radio Resource to the fixed fee of each bag.
Fig. 8 is a flow chart, for example understands according to the present invention the operation when communicating between mobile radio station and the GPRS network.Shown in piece 610, terminal equipment start voice, data or multimedia application 50-530.At piece 620, application program indicates a service quality to quality of service application 550.Perhaps, can be 630, quality of service application 550 receives a service specified quality from the user of terminal equipment.The user indicates service quality will be in following detailed introduction.
Continue the description of Fig. 8, at piece 640, quality of service application 550 passes to portable terminal with a clear and definite service quality, for example, utilizes a R interface and a target resource agency 560 based on port.At piece 650, portable terminal utilizes ERANAP 580 to transmit a service specified quality to GPRS RAN.Subsequently, at piece 660, according to the performance characteristics of service quality and GPRS RAN, GPRS RAN sets up the communication of same voice, data or multimedia application.
Among Fig. 9 A and the 9B, for example understand in one 8 phase shift keying (8PSK) and Gaussian Minimum Shift Keying (GMSK) pattern the example of RLC/MAC piece in the GPRS/EGPRS system respectively.Through chnnel coding, the RLC/MAC piece is across 4 time slots, and these time slots distribute (interlocking) on 4 frames, and each frame comprises 8 time slots, GSM time division multiple access (TDMA) frame structure.Coded data generally is at these 4 time slot interleavings.Accessible encoding rate can change between 1/12 to 1/5 (8PSK) and between 1/4 to 1/2 (GMSK).The RLC/MAC piece comprises a up link mark (USF) territory, and this territory allows portable terminal to understand the state of uplink channel.A loadtype (PT) mark shows the type of real time business.Temporary flow identity symbol (TFI) territory, the Temporary Block Flow under the definition of data.A power reduction (PR) territory shows with respect to the BCCH in the next RLC/MAC piece, the reduction on the power.A Coding andPuncturing (CPS) territory indicates the chnnel coding agreement.Whether an encrypted identifier (K) indicates encrypts.CRC is a cyclic redundancy check (CRC) territory.For the present technique professional person, the territory in the RLC/MAC piece is known, need not be further described herein.
Referring now to Figure 10, introduce an example of the present invention.In this embodiment, the data cell of supposing one 36 eight bit byte is circled round coding so that connect with a RLC/MAC title among Fig. 9 A and the 9B.These 36 eight bit byte distribution in the RLC/MAC piece are by deciding for the staggered of RAB agreement.For example, as shown in figure 10, before the RLC/MAC of structural map 9A or 9B piece, two 36 eight bit bytes can be interlocked by the diagonal angle.Perhaps, staggeredly can become piece to carry out.The staggered characteristic of communication can be stored in the RLC/MAC context, the communication after consulting for mistake, and this feature does not need to send through Radio Link.
As above described in conjunction with Figure 8, at piece 630, the present invention can also estimate user's service specified quality, rather than (perhaps replenishing) specified by application program 510-530.Figure 11 A and 11B for example understand the man-machine interface (MMI) on the mobile radio station, allow user's specified services quality.Figure 11 A for example understands the mobile radio station 900 that screen displaying 910 is arranged, and shows a service quality slide rule 920 on it.Figure 11 B for example understands the upwards button 930 that shows on the display 910 of mobile radio station 900 and to knob down 940.For the present technique professional person, the others of the design of relevant mobile radio station 900 are known, need not do further introduction herein.
Therefore, the user can utilize button, slide block control or other known user interface dynamically to specify desired service quality.The simple service quality that the user can select can be general, for example less time-delay or than multiple-time delay.Another control can be used to control the appreciable service quality of voice or video application, and this finishes than good quality or than low quality by specifying.User's selection can utilize Venn figure or other scheme to be mapped as from the retrievable characteristic of network.User's input can be translated into the staggered instruction with the staggered 80ms of changing into of 40ms.Subsequently, after having carried out consultative process, data division can suitably be interlocked again.
Be converted to another kind of interlace scheme from a kind of interlace scheme and can be thus completed, that is, insert the pseudo-frame that allows provisional flow process to suspend, and rebulid Temporary Block Flow (TBF) at rlc/mac layer.Perhaps, can utilize switching process to finish conversion.Can also utilize other standard link adaptation process to finish conversion from a kind of encoding scheme to another kind of encoding scheme.A kind of use of service quality scheme is to limit performance, thereby can use lower data transfer rate, allows with cheaper price visit Radio Resource.Therefore, the user can control service quality and service price.
From the angle of service-oriented, an IP-based transmission network can not recognized the specified application of request Internet resources fully.In other words, in an IP-based transmission network, all data are all treated equally.But, unfortunately, the application program of on terminal equipment, carrying out, for example voice, data or multimedia may require different service quality to reach acceptable performance.Voice, data processing or multimedia application that the present invention allows mobile radio station to carry out according to terminal equipment are specified a service quality, so that Radio Access Network and/or other network can provide acceptable service quality, and needn't know performed application program.
At accompanying drawing with in describing, introduced typical preferred embodiment of the present invention, although used specific term, but they just are used for describing the present invention, do not play qualification, scope of the present invention is listed in the appended claims.
