Description
Technical field
The present invention relates to the information transmission technology, relate in particular to transmission method, system, terminal, base station and the radio network controller of terminal ability information.
Background technology
Terminal ability information comprises that the high speed uplink packet of terminal inserts (HSUPA, High SpeedUplink Packet Access) ability rating information and high speed downlink packet insert (HSPDA, HighSpeed Downlink Packet Access) ability rating information.Particularly, HSUPA ability rating information is meant peak transfer rate, maximum timeslot number, the modulation system ability of the enhancing dedicated channel (E-DCH, Enhanced DedicatedChannel) that terminal can be supported and the maximum carrier number that can support; Similarly, HSDPA ability rating information is meant peak transfer rate, maximum timeslot number, the modulation system ability of the high-speed packet DSCH Downlink Shared Channel (HS-DSCH, High Speed Downlink Shared Channel) that terminal can be supported and the information such as maximum carrier number that can support.Terminal ability information also comprises the greatest physical channel number of the transmission that terminal can be supported in the ascending time slot etc.Terminal sends terminal ability information to after the base station, and just dispatch terminal according to this terminal ability information the base station.
Describe below by method illustrated in figures 1 and 2 transmission method terminal ability information in the prior art.Fig. 1 is configured under cell private channel (CELL-DCH, the CELLDedicated Channel) state from idle pulley for terminal, the transfer approach of terminal ability information; Fig. 2 is configured under cell forward access channel (CELL-FACH, the CELL Forward AccessChannel) state from idle pulley for terminal, the transfer approach of terminal ability information.
Referring to Fig. 1, the transmission method flow chart one for the prior art terminal ability information may further comprise the steps:
Step 101, at mobile cellular sub-district establishment stage, radio network controller (RNC, RadioNetwork Controller) is finished the configuration of Common transport channel and is set up process by setting up process with the Common transport channel of the Iub interface of base station and the base station is carried out alternately.
So-called Common transport channel is meant, allows a plurality of users to send or receive data simultaneously on described Common transport channel.Common transmission information comprises Random Access Channel (RACH, Random AccessChannel) and forward access channel (FACH, Forward Access Channel) etc., RACH and FACH are to be the common signal channel of unit with the sub-district, terminal and network must be by the configuration informations of described Common transport channel intercorrelation, set up process to finish the connection that business or signaling trigger, and obtain the configuration information etc. of dedicated channel and other private resources by described Common transport channel.
Step 102, finish the Iub interface relevant configuration after, RNC is notified to terminal by system message broadcasting with the configuration information of RACH and FACH.
Step 103 behind the starting up of terminal, reads the system message of broadcasting, obtains the configuration information of RACH and FACH.
Step 104 need be set up professional the connection or the signaling connection if be in the terminal of idle pulley, and terminal is set up request message to RNC by the wireless connections that RACH sends radio resource control layer.
Terminal is set up to carry in the request message to connect in wireless connections and is set up the capability indication information whether reason and terminal support HSUPA and HSDPA, and the capability indication information of described HSUPA is with the support of a bit information bit representation or do not support HSUPA to operate; The capability indication information of described HSDPA is with the support of a bit information bit representation or do not support the HSDPA operation.
The capability indication information whether carried terminal in the request message supports HSUPA and HSDPA is set up in the wireless connections that terminal sends by RACH, but do not carry concrete terminal ability information, described terminal ability information comprises HSUPA and the HSDPA ability rating information that terminal is supported, below its reason is described.Send to RNC in order timely and accurately request message to be set up in wireless connections, agreement stipulates that this message must transmit in the Transmission Time Interval (TTI, Transmission TimeInterval) of RACH, be equivalent to stipulate the full-size of this message.The full-size that request message is set up in wireless connections is subject to the TTI length of RACH and the stock number of RACH.RACH is a common signal channel, and terminal is the request message of setting up such as wireless connections in the call establishment stage transmission by this channel, and sends very small amount of business datum.If the configuration of the stock number of RACH is more, will cause the wasting of resources inevitably because of this channel seldom is used; If the TTI of RACH configuration is longer, will have influence on the capacity of RACH; Therefore, the stock number of RACH is not too large generally speaking, and TTI can be not oversize.Like this, the size-constrained of request message set up in the wireless connections that caused RACH to go up carrying, and concrete terminal ability information need be represented with many information bits, causes stipulating in traditional standard, and wireless connections are set up in the request message can not carry concrete terminal ability information.
Step 105 after RNC receives wireless connections and sets up request message by RACH, is set up reason and whether terminal supports the capability indication information of HSUPA and HSDPA to admit control according to its entrained connection.
The described admittance control of this step comprises: if the RNC decision uses E-DCH and HS-DSCH to be Terminal Service, then initiate the dedicated process of the Radio Link foundation of Iub interface chain of command, by the dedicated process that Radio Link is set up, the configuration information of mutual E-DCH and HS-DSCH between RNC and the base station.
Because the indication information whether carried terminal only supports HSUPA and HSDPA is set up in the request message in the wireless connections that terminal sends, RNC is not before receiving the HSUPA and/or HSDPA ability rating information that terminal sends, and RNC can only give the base station with the HSUPA and/or the HSDPA ability rating information configuration of minimum.The HSUPA of minimum described here and/or HSDPA ability rating represent, terminal is as long as support HSUPA and/or the HSDPA operation, and so correspondingly this terminal just needs to be provided with the timeslot number supported at least, modulation system etc.Follow-up, the base station just uses the ability rating of minimum HSUPA and/or HSDPA that terminal is dispatched.Like this, if the tenability grade of this terminal own is than higher, because can't set up request message by wireless connections sends the terminal capability class information of reality to network in time, the data peaks speed that can cause terminal to obtain is less than normal, thereby influences the QoS of terminal.
Step 106, behind the dedicated process of Iub interface chain of command, RNC sets up message by FACH with the wireless connections of radio resource control layer and sends terminal earlier in the completing steps 105.
The information configuration that message is carried E-DCH and HS-DSCH is set up in the wireless connections of radio resource control layer, and sets up the state indication of carrying the radio resource control layer that is disposed in the message in wireless connections.Under the conventional situation, network need just can carry out E-DCH and HS-DSCH data to terminal configuration to the CELL-DCH state of radio resource control layer and send and receiving course.
Step 107, after terminal receives that by FACH message is set up in wireless connections, set up the E-DCH that carries in the message and/or the configuration information of HS-DSCH is configured according to wireless connections, after finishing configuration, terminal is finished message by E-DCH with the wireless connections foundation of radio resource control layer and is sent to RNC, and finishes message by wireless connections foundation and give RNC with the HSUPA and the HSDPA ability rating feedback information of terminal reality.
Step 108, RNC sets up in the process at follow-up service bearer after having obtained the HSUPA and/or HSDPA ability rating information of terminal, sends the HSUPA of terminal and the ability rating information of HSDPA to base station by wireless links reconfiguration course.
Then, dispatch terminal according to the HSUPA of terminal transmission and/or the ability rating information of HSDPA the base station.
Referring to Fig. 2, be the transmission method flowchart 2 of prior art terminal ability information, this method may further comprise the steps:
Step 201～204, identical with step 101～104.
Step 205 after RNC receives wireless connections and sets up request message by RACH, is set up reason and whether terminal supports the capability indication information of HSUPA and HSDPA to admit control according to its entrained connection.
The described admittance control of this step comprises: if RNC carries out transfer of data according to setting up the decision of reason and terminal capability indication information with terminal configuration under the CELL-FACH state, so, RNC need not to initiate the dedicated process that the Radio Link of Iub interface chain of command is set up, but directly by descending FACH message being set up in the wireless connections of radio resource control layer sends to terminal.
Because under traditional CELL-FACH state, up by RACH transmission data, descending by FACH reception data, described RACH and FACH set up process by the Common transport channel of sub-district establishment stage and set up, and send to terminal so can directly by descending FACH message be set up in the wireless connections of radio resource control layer.
After step 206, the wireless connections that terminal go up to receive according to FACH are set up message and finished configuration, by RACH wireless connections are set up and to finish message and send to RNC, the ability rating information of carrying HSUPA and/or HSDPA in the message of finishing is set up in wireless connections.
If the subsequent network decision continues terminal configuration is carried out transfer of data under the CELL-FACH state, even terminal is finished message with terminal ability information by wireless connections foundation and is sent to RNC, because under the CELL-FACH state, do not have special-purpose chain of command signaling procedure on the Iub interface between RNC and the Node B, RNC also just can't send terminal ability information to base station by the dedicated signaling process of chain of command.Correspondingly, the base station still can only use minimum ability rating information that terminal is dispatched, and like this, even terminal has higher ability rating, also can't obtain the higher data peak rate.
In high-speed packet access (HSPA, High Speed Packet Access) system and in the system before the HSPA system, descending use FACH receives data, and up use RACH sends data.In the booster stage system of HSPA, in order to improve the speed of the descending FACH of being mapped to, propose in the CELL-FACH state, descending use HS-DSCH replaces traditional FACH, uply still uses RACH, and defines this state for strengthening the CELL-FACH state.The key character that strengthens the CELL-FACH state is, terminal is up to send data by RACH, descending by HS-DSCH reception data, especially, can not only be used for transmitting wireless signaling carrying related data under the CELL-FACH state, equally also can transmit the related data of wireless traffic carrying.
In the booster stage system of HSPA,, also proposed the data map of the former RACH of being mapped to is gone up transmission to E-DCH in order further to improve the transmission rate of RACH under the CELL-FACH state.In the CELL-FACH state of the booster stage system of HSPA in the future, will occur up by E-DCH carrying upstream data, descending trend by HS-DSCH bearing downlink data.Especially, when the RACH data are transmitted by E-DCH, the size that request message is set up in wireless connections in the step 204 will no longer be subject to the stock number of RACH and the size of TTI.Yet, even like this, RNC finishes message by wireless connections foundation and obtains terminal ability information in the step 206, for being configured to the terminal that strengthens the CELL-FACH state, owing to there is not the signaling procedure of Iub interface chain of command special use, therefore RNC can't send terminal ability information to base station, and the base station also can only use minimum HSDPA and/or HSDPA ability that terminal is dispatched.
By above analysis as seen, in the booster stage system of HSPA, for terminal from idle pulley to being configured under the CELL-FACH state, exist because of terminal ability information can't being sent to the base station, and the problem that causes the base station can only use the minimum ability grade that terminal is dispatched.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
In the booster stage system of HSPA, allow the terminal under the CELL-FACH state to use E-DCH to upload data.E-DCH is a shared channel, the E-DCH resource is by the HSUPA scheduler control of base station side, terminal is not being received under the E-DCH resource situation of base station assigns, need uplink scheduling information be sent to the base station by E-RUCCH, the base station is a terminal distribution E-DCH resource according to the uplink scheduling information that receives again.
The present invention proposes in the booster stage system of HSPA, terminal from idle pulley to being configured under the CELL-FACH state, the transfer approach of terminal ability information, comprise following two kinds: method 1, by up enhancing random access control channel (E-RUCCH, E-DCH Random Uplink ControlChannel) method of carried terminal ability information, this method does not receive that in terminal the uplink scheduling information that will comprise terminal ability information by E-RUCCH sends to the base station under the E-DCH resource situation of base station assigns; Method 2, terminal by E-DCH after wireless connections are set up request message carried terminal ability information and are sent RNC to, RNC sends the method for base station to by Iub interface user side data frame or control frame carried terminal ability information, after this method is received the E-DCH resource of base station assigns in terminal, set up request message carried terminal ability information by E-DCH in wireless connections and send RNC to.Describe respectively below:
Method one, the method by E-RUCCH carried terminal ability information.
Terminal need send to the base station with uplink scheduling information by E-RUCCH not receiving under the E-DCH resource situation of base station assigns, and the base station is a terminal distribution E-DCH resource according to the uplink scheduling information that receives again.Comprise highest priority logical channel sign (HLID in the described uplink scheduling information, Highest PriorityLogical Channel Identifier) information, buffer memory total amount (the TEBS of all logic channels, Total E-DCHBuffer Status), the highest priority logical channel buffer memory accounts for the ratio (HLBS of total buffer memory, HighestPriority Logical Channel Buffer Status), path loss (the SNPL of Serving cell and adjacent sub-district, Serving cell and Neighbour cell Path loss), and terminal power headrooms information (UPH, UserEquipment Power Header Room).Generally speaking, may there be a plurality of different logic channels simultaneously in the terminal that is in the CELL_DCH state, and HLID, HLBS can clearly give the base station with the buffer status report of a plurality of logic channels relatively with TEBS.In addition, E-RUCCH also is a shared channel, go back carried terminal identification information (E-RNTI, E-DCH Radio NetworkTemporary Idenitifier) except carrying uplink scheduling information, described special E-RNTI is given terminal by the dedicated signaling process by network allocation.
After the uplink scheduling information and E-RNTI of base station by the transmission of E-RUCCH receiving terminal, according to logic channel buffer memory situation of carrying in the uplink scheduling information and physical layer metrical information is suitable physical code channel resource and the power resource of this terminal distribution, the base station is by (E-AGCH, E-DCH Absolute GrantChannel) physical code channel resource and the power resource that distributes sent to terminal, and carry out addressing by the terminal identification information of carrying on the E-AGCH.Terminal is decoded to E-AGCH according to own identification information, receive the physical code channel resource and power resource that the base station issues after, by E-DCH transmission upstream data.
In the booster stage system of HSPA, after the physical code channel resource and power resource that the reception base station issues, the terminal of idle condition sends upstream data by up E-DCH, comprising: the terminal of idle condition is initiated wireless connections by E-DCH and is set up.Before the terminal of idle condition is initiated wireless connections foundation, need by Common Control Channel (CCCH, Common Control Channel) request message is set up in the wireless connections of carried terminal, CCCH is the logic channel of corresponding E-RUCCH, generally speaking, the terminal that is in idle condition can only insert request at random by Common Control Channel CCCH transmission.Just, only there is a logic channel in the terminal that is equivalent to idle condition, i.e. CCCH, like this, TEBS in the uplink scheduling information is enough buffer status of the CCCH logic channel of expression terminal just, and HLID and the HLBS in the uplink scheduling information is redundant information at this moment.Therefore, method one of the present invention has proposed to use the HSUPA ability rating information that HLID in the uplink scheduling information and/or HLBS represent terminal.Flow process below by Fig. 3 is illustrated method one.
Referring to Fig. 3, be the transmission method flow chart one of terminal ability information of the present invention, this method may further comprise the steps:
The information bit of HLID in the uplink scheduling information among the terminal E-RUCCH and/or the information bit of HLBS are set to the HSUPA ability rating information of terminal.For the terminal of using public E-RNTI, terminal by E-RUCCH when the base station sends uplink scheduling information, also send public E-RNTI by E-RUCCH to the base station, the terminal identification information among the present invention among the terminal E-RUCCH is set to public E-RNTI.
The method that public E-RNTI is set comprises following two kinds:
1, RNC disposes public E-RNTI collection to base station and terminal respectively, all signs of this public E-RNTI collection have been represented to send to simultaneously in the uplink scheduling information of base station and have been comprised terminal ability information, when terminal need be passed through E-RUCCH carried terminal ability information, concentrate public E-RNTI of selection to send to the base station from public E-RNTI.
Because the terminal of idle condition can't be obtained special-purpose E-RNTI by the signaling procedure of special use, therefore, the public E-RNTI of the terminal of idle condition obtains by the system message broadcasting process.
2, RNC disposes public E-RNTI collection to base station and terminal respectively, base station assigns is divided into specific public E-RNTI and unspecific public E-RNTI for the public E-RNTI of terminal, specific public E-RNTI has represented to send to simultaneously in the uplink scheduling information of base station and has comprised terminal ability information, unspecific public E-RNTI has represented to send to simultaneously in the uplink scheduling information of base station and has not comprised terminal ability information, when terminal need be passed through E-RUCCH carried terminal ability information, select a specific public E-RNTI to send to the base station.
Below step 301 is illustrated, at present in the standard, the single carrier HSUPA ability rating of terminal is divided into 5 classes, be numbered 1-5 respectively, use 3 bits to represent,, use " 001 " expression ability rating 2 such as using " 000 " expression ability rating 1, use " 100 " expression ability rating 5, or the like.The multicarrier number that present normalized definition terminal can be supported is 12, use 4 bits just can represent, such as the carrier wave number of using " 0000 " to express support for is 1, the carrier wave number of using " 0001 " to express support for is 2, by that analogy, the carrier wave number of using " 1011 " to express support for is 12, or the like.The multicarrier number that the multi-carrier HSUPA ability of terminal uses single carrier ability and terminal to support is simultaneously represented, therefore the multi-carrier HSUPA ability of terminal just can use 3 bits to represent the single carrier ability, use 4 bits to represent the multicarrier number simultaneously, that is to say the multi-carrier HSUPA ability rating information of using 7 bits to represent terminal.At present HLID and the HLBS that defines in the agreement takies 4 bit information positions respectively, therefore can use 7 bit informations in HLID and the HLBS information bit to represent the multi-carrier HSUPA ability rating information of terminal.
For making the understanding of terminal and base station be consistent, need in base station, terminal, to set up in advance the information bit of identical HLID and HLBS and the mapping relations of terminal multi-carrier capability class information.Bright for instance, at first each information bit to HLID and HLBS is numbered, be numbered b1-b4 respectively such as information bit with HLID, the information bit of HLBS is numbered b5-b8 respectively, get three bits of b1-b3 and represent the single carrier ability rating of terminal, get the carrier wave number that the b4-b7 bit represents that terminal can be supported.
The public E-RNTI that carry by E-RUCCH according to terminal step 302, base station determines to comprise in the uplink scheduling information terminal ability information.
The meaning of the bit information of traditional E-R UCCH is different with the meaning of the bit information of the E-RUCCH of carrying terminal HSUPA ability rating information, therefore the E-RUCCH codec format should be determined in the base station when decoding, and described E-RUCCH codec format comprises the mapping relations of the bit information position of setting up with terminal.
Corresponding to two kinds of methods that public E-RNTI is set in the step 301, the base station determines that the method that whether comprises terminal ability information in the uplink scheduling information comprises following two kinds of situations:
1, determines the codec format of E-RUCCH according to the public E-RNTI that carries on the E-RUCCH: if the base station is judged one that has carried on the E-RUCCH in the public E-RNTI set that belongs to network configuration, this E-RUCCH goes up carried terminal ability information in the corresponding uplink scheduling information that sends so, need mapping relations, uplink scheduling information is decoded according to the bit information of setting up in advance with terminal; If the base station is judged one that does not carry on the E-RUCCH in the public E-RNTI set that belongs to network configuration, this E-RUCCH goes up in the corresponding uplink scheduling information that sends does not so have the carried terminal ability information, according to coding/decoding method of the prior art uplink scheduling information is decoded.
2, determine the codec format of E-RUCCH according to specific public E-RNTI: if the base station is judged one that has carried on the E-RUCCH in the specific public E-RNTI set, this E-RUCCH goes up carried terminal ability information in the corresponding uplink scheduling information that sends so, need mapping relations, uplink scheduling information is decoded according to the bit information of setting up in advance with terminal; If the base station is judged one that does not carry on the E-RUCCH in the specific public E-RNTI set, this E-RUCCH goes up in the corresponding uplink scheduling information that sends does not so have the carried terminal ability information, according to coding/decoding method of the prior art uplink scheduling information is decoded.
Decoding to described uplink scheduling information according to the E-RUCCH codec format that sets in advance in step 303, base station, obtains terminal ability information.
Described E-RUCCH codec format comprises the mapping relations of the bit information position of setting up with terminal, and the base station is determined in the E-RUCCH information and carried terminal ability information, then according to these mapping relations terminal ability information is decoded out.Such as, the base station is according to being numbered with the same mode of terminal each information bit to HLID and HLBS, the information bit of HLID is numbered a b1-b4 respectively, the information bit of HLBS is numbered b5-b8 respectively, three bit information positions of b1-b3 are decoded as the single carrier ability rating of terminal, three bit information positions of b4-b7 are decoded as the carrier wave number that terminal can be supported.
The wireless connections that method two, terminal send the carried terminal ability information by E-DCH set up request message to RNC after, RNC sends the method for base station to by Iub interface user side data frame or control frame carried terminal ability information.
Under traditional situation, terminal is finished message by wireless connections foundation and is sent terminal ability information to RNC, RNC again with terminal ability information by and the base station between the chain of command process of Iub interface, send the base station to such as Radio Link foundation, increase and reconfiguration course.Yet in the HSPA enhanced system, under terminal was configured to cell forward access channel status, the chain of command of Iub interface did not have special-purpose signaling procedure, therefore can't send terminal ability information to base station.Based on this, the present invention proposes terminal and sets up request message to RNC by the wireless connections that E-DCH sends the carried terminal ability information, and RNC sends the method for base station to by Iub interface user side data frame or control frame carried terminal ability information then.
Referring to Fig. 4, be the transmission method flowchart 2 of terminal ability information of the present invention, this method may further comprise the steps:
Step 401, terminal are set up carried terminal ability information in the request message in wireless connections, send the wireless connections request message to RNC by E-DCH.
