Abstract
Techniques for efficiently configuring and reconfiguring calls using a set of default configurations and differential encoding are described. At the network side, a configuration to use for communication with a wireless device is initially selected. A default configuration is identified from among a set of default configurations. The differences, if any, between the selected configuration and the default configuration are ascertained. An identity for the default configuration and the differences, if any, are sent to the wireless device to convey the selected configuration. At the wireless device, the message containing the identity for the default configuration is initially received. The default configuration is obtained from a memory based on the identity. A determination is made whether the message contains differences between the default configuration and the selected configuration. Values for the default configuration are replaced with the differences, if any, sent in the message.

Fig. 1 shows UMTS terrestrial radio Access Network (UTRAN) 100, and it comprises the many base stations with many wireless device communications.For simplicity, only figure 1 illustrates three base stations 110 and a wireless device 120.The base station is a fixed station, and also can be called as Node B, base transceiver subsystem (BTS), access point or some other terms.Each base station covers for the specific geographical area provides communication.Base station and/or its overlay area can be depended on the context that term uses and be called as " sub-district ".Wireless device can be that fix or mobile, and also can be called as subscriber equipment (UE), travelling carriage, terminal or some other terms.Wireless device can be depending on whether this wireless device is in active state, whether soft handover is supported and whether this wireless device is in the soft handover, and any given time on down link and/or up link with one or more base station communications.Down link (or forward link) is meant the communication link from the base station to the wireless device, and up link (or reverse link) is meant the communication link from the wireless device to the base station.Radio network controller (RNC) 130 is connected to base station 110 and to coordinating and control in these base stations.In the following description, wireless device is called as UE, and network terminal (for example, Node B and RNC) is called as UTRAN.
Fig. 2 shows the protocol stack 200 by 6 definition of 3GPP version.Protocol stack 200 comprises radio resource control (RRC) layer 210, radio link control (RLC) layer 220, medium access control (MAC) layer 230 and physical layer 240.Rrc layer 21O is the sublayer of L3 layer.Rlc layer 220 and MAC layer 230 are the sublayers that are commonly referred to the L2 layer of data link layer.Physical layer 240 is commonly referred to the L1 layer.
Rrc layer provides the message transport service to Non-Access Stratum (NAS), and NAS supports the business between UE and the core net CN and the functional layer of signaling message, and wherein UTRAN is connected by interface with CN.Rrc layer also is responsible for the configuration of control L1 and L2 layer.Rlc layer provides reliability of data transmission and carries out the automatic re-transmission of data.In rlc layer, data are processed as belonging to logic channel.The MAC layer shines upon logic channel and/or is multiplexed on the transmission channel, and handles the data of (for example, encode, interweave and rate-matched) each transmission channel.Physical layer is provided for transmitting the data of MAC layer and the mechanism of more high-rise signaling.Physical layer is mapped to transmission channel on the physical channel, handles the data of (for example, channelizing and add scramble) each physical channel, and every group of physical channel is carried out power control.

Fig. 3 shows the state of the UE among the 3GPP and the state diagram 300 of pattern.For simplicity, state diagram 300 only shows relevant state and pattern, and all possible state and pattern are not shown.After start, UE carries out cell selecting to find from wherein receiving the sub-district that is fit to of service.UE can be switched to idle pulley 310, UTRA RRC connection mode 320 or GSM connection mode 330 then, and this depends on whether UE has any activity and UE whether to communicate by letter with UTRAN or GSM/EDGE radio access network (GERAN).Under idle pulley, UE is to network registration, listening paging message, and upgrade its position to network where necessary.UE can be depending on its state and configuration, and carries out the operation that receives and/or transmit data with UTRAN under UTRA RRC connection mode, carries out the operation of reception and/or transmission data under the GSM connection mode with GERAN.UE can change so that carry out handover between UMTS and GSM between UTRA RRC connection mode and GSM connection mode.
When in UTRARRC connection mode following time, UE can be in four kinds of a kind of states in the possible RRC state: CELL_DCH state 322, CELL_FACH state 324, CELL_PCH state 326 or URA_PCH state 328, wherein DCH represents dedicated transmission channel, FACH represents forward access channel, PCH represents paging channel, and URA represents the UTRAN Registration Area territory.Table 1 provides the brief explanation of four kinds of RRC states.These patterns and state are recorded and narrated in 3GPP TS 25.331 V6.2 in detail.
Table 1
| State | Explanation |
| CELL_DCH | DPCH is tasked UE by branch and is used for up link and down link; And the combination of special-purpose and shared transmission channel is available for UE. |
| CELL_PACH | There is not DPCH to be tasked UE by branch; Public or the shared transmission channel of acquiescence on the up link is assigned to UE to be used for access network; And UE monitors continuously such as the signaling that reconfigures message on the FACH on the down link |
| CELL_PCH and URA_PCH | There is not DPCH to be tasked UE by branch; UE periodically monitors beep-page message on PCH; And UE is not allowed to transmit on up link |
UE can: (1) is set up the process that RRC connects and is transformed into CELL_DCH state or CELL_FACH state from idle pulley by execution; (2) by carry out discharging process that RRC connects from CELL_DCH state or CELL_FACH state exchange to idle pulley.UE can: (1) reconfigures process by execution and another state under from CELL_DCH state or CELL_FACH state exchange to UTRA RRC connection mode; (2) also reconfigure process and conversion between the configuration of the difference under the CELL_DCH state by execution.UTRAN can be based on the activity of UE and is ordered UE to be in a kind of state in four kinds of states under the UTRA RRC connection mode.The connection and the process that reconfigures are recorded and narrated in 3GPP TS 25.331V6.2.In Fig. 3, wherein carried out the conversion that reconfigures and illustrated with solid line with single arrow, wherein there is not to carry out the conversion reconfigure to have being shown in dotted line of single arrow.
3GPP has defined and has been used for that radio bearer (RB) reconfigures, transmission channel (TrCH) reconfigures the process that reconfigures that reconfigures with physical channel.Radio bearer is to pass on the service of business datum by L2 layer being used for of providing between UE and UTRAN.One or more radio bearers can be kept by the peer-entities on the layer 2 among UE and the UTRAN.Each radio bearer is relevant with the customized configuration of logic channel, transmission channel and physical channel.For example, the configuration of each radio bearer can be described employed particular channel, the speed of each channel, and the channel code of physical channel (ovsf code), or the like.The amount of the activity at UE place is depended in the configuration of each radio bearer.For example, (1) then can place UE the CELL_DCH state if UE has data to transmit or to receive; Perhaps (2) then can place UE the CELL_FACH state if UE does not have data to transmit or to receive.If activity changes, then UE also can change its configuration.The configuration change of UE reconfigures process by execution and finishes.
Fig. 4 shows the signaling process 400 that is used to the process that reconfigures.UTRAN reconfigures message by transmission and starts the process of reconfiguring, and reconfiguring message can comprise: (1) is new to dispose for information about, for example, and the new parameter value of transmission channel and physical channel; (2) activationary time, it is to use the time that reconfigures.UTRAN can start independently and reconfigures, perhaps can be in response to receiving from the signaling of UE and start and reconfigure.successfully receive reconfigure message after, UE carries out reconfiguring of the channel be modified.UTRAN carries out similarly and is modified reconfiguring of channel.Then, finish if reconfigure successfully, then UE sends to reconfigure and finishes message (as shown in Figure 4), does not complete successfully if perhaps reconfigure, and then UE sends and reconfigures failed message (not shown among Fig. 4).
Depend on that what carrying out is which kind of reconfigures process, UTRAN can send different message with UE.For example, can be radio bearer reconfigures and sends radio bearer and reconfigure message and radio bearer and reconfigure and finish message, can be transmission channel and reconfigure and send transmission channel and reconfigure message and transmission channel and reconfigure and finish message, and can be physical channel and reconfigure and send physical channel and reconfigure message and physical channel and reconfigure and finish message.Among Fig. 4 reconfigure message and reconfiguring finish message often can with above-mentioned message to or any corresponding general message of some other message pair.
Typically, reconfigure the various information elements (IE) that message comprises the various parameters relevant with communication, as described below.For example, radio bearer reconfigures message and can comprise TrCH information element of UE information element, CN information element, UTRAN mobility information element, RB information element, down link and uplink transmission channels etc.Typically, it is very large reconfiguring message.
Reconfigure that message can be depending on the size of whole message and processed as one or more protocol Data Units (PDU) at rlc layer.Each PDU can transmit in a Transmission Time Interval (TTI), and wherein TTI is used for signaling, and is typically 40 milliseconds (ms).The whole message that reconfigures of the disposable transmission of UTRAN.UE sends the negative response (NAK) of each PDU that is not correctly received, and UTRAN can retransmit this PDU one or many till UE correctly receives this PDU.Table 2 receives the probability that reconfigures message mistakenly for the re-transmission of the PDU of different numbers and different number of times shows.The wrong probability that receives any given PDU of table 2 supposition is 5%, and the probability that mistake receives any NAK is 5%, and UE need correctly receive all PDU of message.
Table 2
| The PDU number of message | Retransmit for 0 time | Retransmit for 1 time | Retransmit for 2 times | Retransmit for 3 |
| 1 | 5.00％ | 0.49％ | 0.05％ | 0.00％ |
| 2 | 9.75％ | 0.97％ | 0.10％ | 0.01％ |
| 3 | 14.26％ | 1.46％ | 0.14％ | 0.01％ |
| 4 | 18.55％ | 1.94％ | 0.19％ | 0.02％ |
| 5 | 22.62％ | 2.41％ | 0.24％ | 0.02％ |
| 6 | 26.49％ | 2.89％ | 0.28％ | 0.03％ |
| 7 | 30.17％ | 3.36％ | 0.33％ | 0.03％ |
| 8 | 33.66％ | 3.83％ | 0.38％ | 0.04％ |
For the example shown in the table 2, if message is made up of two or still less PDU, then UE after once retransmitting will with 99% or higher probability (corresponding to 1% or lower message error probability) correctly receive and reconfigure message, if and message is by forming more than two PDU, then UE after twice re-transmission will with 99% or higher probability correctly receive and reconfigure message.Each PDU can send in the TTI of a 40-ms, and the delay of re-transmission may be 200ms, and the processing time at UE place may be 100ms.In this case, (have once retransmit) total transmission and the processing time with message of two PDU can be calculated as: (2 * the 40)=80ms+ retransmission delay 200ms+UE processing time 100ms=380ms total delay that is used to transmit.(having twice re-transmission) total transmission and processing time with message of eight PDU can be calculated as: (8 * the 40)=320ms+ that is used to transmit is used for the 400ms+UE processing time 100ms=820ms total delay of twice re-transmission.3GPP version 6 and more the size that reconfigures message of older version be commonly referred to as 4 to 8 PDU.
Reconfiguring the activationary time of indicating in reconfiguring message comes into force.UTRAN can be fully far away towards being set in the future with activationary time, thinks that message reserves sufficient transmission and number of retransmissions, so that UE can reach the correct probability of acceptance of given expectation.If message is just correctly received behind activationary time, then reconfiguring process will fail, and (for example, under the situation about reconfiguring of compact model pattern) in some cases, radio link will occur and fail.For above-mentioned example, form by two PDU if reconfigure message, then UTRAN can be arranged on activationary time 380ms in the future, if perhaps message is made up of eight PDU, then UTRAN can be arranged on activationary time 820ms in the future.These activationary times guarantee UE will with 99% or higher probability correctly receive and reconfigure message.Can activationary time is farther towards being set in the future, to reach the higher correct probability of acceptance (for example, 99.9%).
The transmission time that reconfigures message may be the considerable part that reconfigures in total time of process.For above-mentioned example, the transmission time of (having two PDU's) short message is 380ms, and the transmission time of (having eight PDU's) long message is 820ms.Difference between the transmission time of short message and long message is 440ms.Therefore can be reduced sizable amount the total time that reconfigures process by sending the new configuration messages of short weight.Above analysis not have to consider to carry out the required time quantum of ASN.1 coding and carry out the required time quantum of ASN.1 decoding at UE place at UTRAN place, if considered these two, then when contrasting the transmission of short message and length message, can obtain the more time reduction.Therefore, in order to realize making successfully the minimized target of the required time quantum of pass-along message, the short message that reconfigures is very desirable.
Can be the one group of default configuration of configuration definition that is generally used for communicating by letter.Each default configuration can be relevant with the particular value of unique sign and specific one group of parameter or information element.Sign also can be called as identifier, index etc.Can be by the sign (rather than comprising all information elements) that in reconfiguring message, only comprises given default configuration, and in message, send this default configuration efficiently.The use of default configuration can greatly reduce message size, and this can shorten the total time that reconfigures.
Can be different classes of service (such as, for example session classification, traffic category, interactive classification and background class) define this group default configuration.Other is characterised in that strict low delay and limited delay change so that the time relationship between the maintenance information entity conversation class.Some exemplary application of carrying this business have voice, video and video conference.Traffic category is characterised in that limited delay changes, and some exemplary application of carrying this business have fax and stream audio and stream video.Other is characterised in that the maintenance (or low packet error rate) of request pattern and payload content interactive class.A kind of exemplary application of carrying this business is a network browsing.Background class is characterised in that the maintenance to passing time relative insensitivity and payload content.Download on the backstage that a kind of exemplary application of carrying this business is an Email.
In one embodiment, at first define other default configuration of conversation class, because these configurations are being that requirement is the harshest aspect the stand-by period typically.Can suitably define the default configuration of traffic category, interactive classification and background class then.This embodiment can reduce the size of the group of default configuration.In another embodiment, the configuration of describing among TS 25.993 V6.10 can be checked, and the group of the subclass of these configurations can be selected as default configuration.In another embodiment, the default configuration of listing in the table 3 of recording and narrating in TS 25.331 V6.2 can be used as default configuration.In table 3, CS represents circuit switching.Default configuration among TS 25.331 V6.2 is used for routinely: (1) is setting up the RRC connection when idle pulley is transformed into connection mode; And (2) handover from GSM to UMTS.Usually, each default configuration is relevant with the particular default of specific one group of information element.The information element of the default configuration shown in the table 3 and their default value are presented in the chapters and sections 13.7 of TS25.331 V6.2.
Default configuration among the table 3-TS 25.331

Use no matter select where organize default configuration, all may have many such situations, that is, the selected configuration that is used for using also is not included in the default configuration group.Under each such situation, can transmit selected configuration by the message that reconfigures that transmission comprises all information elements of this configuration.As mentioned above, this transmission time that reconfigures message may be very long.
In one aspect, differential coding can be used for being not included in the selected configuration of the group of default configuration.Differential coding allows to transmit efficiently not and the accurately selected configuration of coupling of any one default configuration.This is by the sign of the default configuration that sends the selected configuration of (1) the most approaching coupling and the difference between (2) selected configuration and the default configuration, realizes.
Usually, selected configuration can send by using minimum signaling, part signaling or complete signaling.For minimum signaling, only send the sign of default configuration.For the part signaling, send the sign of default configuration and the difference between selected configuration and the default configuration.For complete signaling, send complete selected configuration.
Fig. 5 shows and is used to use default configuration and differential coding to send the embodiment of the processing 500 that reconfigures message.At first, select the configuration (flow path block 512) that is used to communicate by letter.Can select configuration in response to the change of the communicating requirement of UE, wherein the change of the communicating requirement of UE can be caused by following reason: the change of data rate, the change of service, the change of QoS, the change of the state in the UTRARRC connection mode is from idle pulley to UTRA RRC connection mode or the conversion of GSM connection mode, from a kind of RAT to another kind of RAT (for example, from GSM to UMTS or from UMTS to GSM) handover etc., the perhaps combination of above reason.Configuration can be selected based on communicating requirement, network load and/or the other factors of UE by the provided for radio resources management entity at UTRAN place.
Then, determine that whether selected configuration is a kind of (flow path block 514) in the default configuration.If determine that at flow path block 516 selected configurations are default configuration, then only adopt the sign of default configuration to form efficiently and reconfigure message, and adopt minimum signaling to send selected configuration (flow path block 518).
If selected configuration is not the result of default configuration and flow path block 516 is ' No ', then identify the default configuration (flow path block 520) of the selected configuration of the most approaching coupling.Determine the difference (flow path block 522) between selected configuration and the default configuration.Difference can be one or more information elements.Then, determine to compare, differential coding whether more efficient (524) is carried out in selected configuration with sending whole selected configuration.Can be more efficient if carry out differential coding, then form and reconfigure message, and adopt the part signaling to send selected configuration (flow path block 526) based on the sign of default configuration and determined difference.Otherwise, adopt all information words of selected configuration usually to form and reconfigure message, and adopt complete signaling to send selected configuration (flow path block 528).Then, will reconfigure message and send to UE (flow path block 530).
Fig. 5 shows and is used to use default configuration and differential coding to generate the particular procedure that reconfigures message.Also can otherwise carry out differential coding.For example, can from the group of default configuration, select the most approaching default configuration that satisfies the communicating requirement of UE.Can change this default configuration as required and satisfy communicating requirement.Change expression be difference between selected configuration and the default configuration, and can adopt the part signaling to send.
Fig. 6 shows the embodiment that is used to receive the processing that reconfigures message 600 of using default configuration and differential coding transmission that is carried out by UE.At first, reconfigure message (flow path block 612) from the UTRAN reception.Determine to reconfigure the sign (flow path block 614) whether message comprises default configuration.If answering is ' Yes ', then obtain default configuration based on this sign (for example, the memory in UE), and the default value of the information element in definite default configuration (flow path block 616).Then, determine to reconfigure message and whether comprise any additional information element (flow path block 618).If answering is ' No ', then selected configuration is to adopt minimum signaling to send, and provides default configuration as selected configuration (flow path block 620).Otherwise if the answer of flow path block 618 is ' Yes ', then selected configuration is to adopt the part signaling to send, and extraction reconfigures the information element (flow path block 622) that sends in the message.The value of the information element that employing extracts is replaced the default value (flow path block 624) of corresponding information element in the default configuration.The default value that keeps all out of Memory elements in the default configuration.Turn back to flow path block 614, do not send default configuration in the message if reconfigure, then selected configuration is to adopt complete signaling to send, and extracts the information element (flow path block 626) of selected configuration from message.No matter how selected configuration sends, all use selected configuration to be used for communication (flow path block 630).
For the situation of selected configuration somewhat different than default configuration, the use of default configuration and differential coding can greatly reduce signaling amount.For instance, UTRAN can select and the identical configuration of default configuration, except the value of " RLC Info " information element.In this case, UTRAN can send the sign of default configuration and only have " RLC Info " information element of desirable value to UE.UE will obtain default configuration based on sign, and will adopt the content of replacing or cover " RLC Info " information element from the value of UTRAN reception.Under the situation that adopts differential coding, if with respect to default configuration, change has taken place in only single parameter or Several Parameters, then parameter that only changes rather than transmission entire arrangement.
Fig. 7 shows the exemplary message 700 that reconfigures of supporting default configuration and differential coding.For this embodiment, message 700 comprises the information element 710 of the sign of carrying default configuration, carries the information element 720 of UE special parameter, the information element 730 of configuration information.Can use nested message structure, in this nested message structure, the information element that is in given level can comprise one or more information elements that are in next lower level.The UE special parameter is possible with the difference of UE different parameter, therefore can send by explicitly in reconfiguring message, rather than be covered by default configuration.An example of UE special parameter is an ovsf code of distributing to the physical channel of UE.Because not having two UE uses identical ovsf code simultaneously, so this parameter can send by explicitly in reconfiguring message.Information element 730 can: save from minimum signaling (1), (2) carry the one or more information elements that are used for the difference between selected configuration of having of part signaling and the default configuration, perhaps (3) carry all information elements of the selected configuration that is used for complete signaling.
Table 4,5 and 6 has been listed and can be included in the various information elements that reconfigure in the message.These information elements are recorded and narrated at TS 25.331, among the V6.2.0.Shown in table 4,5 and 6, utilize complete signaling may need to send many information elements, and utilize the part signaling only need send one or information element seldom, this can greatly shorten message size.
