Description

Realize method for communicating, communication system and device between terminal equipment and the network side

Technical field

The present invention relates to wireless communication technology field, relate in particular to and realize method for communicating, communication system and device between a kind of terminal equipment and the network side.

Background technology

The continuous growth of number of mobile users and high-speed data service demand are promoting further developing of wireless communication technology, and high-speed packet inserts (HSPA, High Speed Packet Access) technology and arises at the historic moment.

The HSPA evolution system is introduced N frequency or multicarrier characteristic, covers with the power system capacity that improves hot zones, and the flexibility that improves the configuring spectrum resource.So-called N frequency or multicarrier characteristic, promptly dispose a plurality of carrier waves in a sub-district, wherein, the carrying as the carrier wave of Primary Common Control Physical Channel common signal channels such as (P-CCPCH) are main carrier, and other do not carry common signal channel and the carrier wave that is generally used for carrying dedicated channel is to assist carrier wave.A N frequency point cell disposes a main carrier usually, and N-1 auxilliary carrier wave.

Usually, in the wireless communication system, for realizing the radio communication between terminal equipment and the network side, network side need dispose the channel that is used for transmission signals on the one hand, comprises that configuration is used to set up the power control information of the carrier information of channel, channel, code channel information or the like channel configuration information; On the other hand, network side need be notified to terminal equipment with channel configuration information, uses which transfer resource and network side to communicate so that terminal equipment can be known, wherein, and the carrier resource that transfer resource comprises channel resource and sets up this channel.

The following describes in the HSPA evolution system, as each network nodes such as radio network controller (RNC), base station (NodeB) and terminal equipments how by knowing that channel configuration information is to realize communicating by letter between network side and the terminal equipment.

Usually, communicate by Iub interface between RNC and the base station.At the sub-district establishment stage, RNC sets up the Common transport channel on the Iub interface chain of command, as setting up Random Access Channel (RACH) that is used as up Common Control Channel and the forward access channel (FACH) that is used as descending Common Control Channel.In addition, on this Iub interface user face, the channel that carries user data is a transmission bearer, and user data distinguishing different transmission bearers, thereby is distinguished in the network address that needs to consult the corresponding transmission bearer of Iub user's face upper signal channel between RNC and the base station.

As previously mentioned, in multicarrier or the N frequency system, related specifications points out that up RACH and descending FACH should be based upon on the main carrier, correspondingly, in the channel configuration information, the carrier information of relevant up RACH or descending FACH all is frequency point information of main carrier, therefore, on the Iub interface chain of command, RNC only needs the frequency point information of main carrier is notified to the base station; On the air interface, RNC only needs the frequency point information of main carrier is broadcast to terminal equipment by system message by the base station.

After the terminal equipment start, read system message obtains the channel configuration informations such as frequency point information of main carrier on RACH and the FACH, with resident in the sub-district.Successfully reside in the terminal equipment in the sub-district if not carrying out any signaling connects, then be in free time (idle) state.When terminal equipment is set up professional connection or signaling connection at needs, ask (RRC connection setup) message to the wireless connections foundation that network side sends Radio Resource control (RRC) layer by up RACH.

Network side can arrive corresponding connection status with terminal equipment configuration according to network load condition, as the CELL_DCH state, and CELL_FACH state etc.Under the CELL_FACH state, terminal equipment is sending the data to network side by RACH, receives the data that network side issues by FACH.Under the CELL_DCH state, terminal equipment can send the data to network side by RACH, receives the data that network side issues by high-speed downlink shared transmission channel (HS-DSCH).

Corresponding to terminal equipment configuration being arrived certain connection status, RNC sets up request message by the wireless connections of the transmission bearer receiving terminal apparatus transmission of the Iub interface user face of RACH correspondence, and set up the relevant information of carrying in the request message according to wireless connections and admit control, after which channel RNC determines to use as the terminal equipment service, on the Iub interface chain of command, sign with this terminal equipment, and the channel configuration information of employed up channel of this terminal equipment and down channel sends to the base station, and set up the private network address of the transmission bearer of up channel correspondence and the private network address of the transmission bearer of down channel correspondence for this terminal at Iub interface user face.

Because the transmission bearer of above-mentioned Iub interface user face is the dedicated transmissions carrying, therefore RNC and base station can be according to the address information of transmission bearer and the signs of the terminal of correspondence, identify this transmission bearer and belong to which terminal equipment, even terminal equipment interface use aloft is the up channel of multicarrier or the down channel of multicarrier.

After the dedicated transmissions carrying of setting up Iub interface chain of command and user's face, RNC is by the transmission bearer of the Iub interface user face of down channel correspondence, message is set up in the wireless connections of radio resource control layer sent to the base station, the base station is arrived the FACH data map on the Secondary Common Control Physical Channel (S-CCPCH), and sends to terminal by air interface.Wherein, owing to FACH only is based upon on the main carrier, so RNC can send to the base station with descending FACH data directly by the transmission bearer of descending FACH correspondence.The relevant information configuration information that carries up channel and down channel in the message is set up in wireless connections, and the indication information of wireless connection conditions is as arriving the CELL_DCH state with terminal equipment configuration.

Usually, network side can arrive the CELL_FACH state with terminal equipment configuration earlier.For requiring the downlink transmission data rate condition with higher, network side can be with terminal equipment configuration to the CELL_DCH state.Because the variation of offered load, different connection status may be moved, and will originally be in terminal equipment under the CELL_DCH state as network side, is configured under the CELL_FACH state; Perhaps will originally be in the terminal equipment under the CELL_FACH state, be configured under the CELL_DCH state; Then correspondingly, terminal equipment connection status of living in takes place under the situation of migration, and network side need be reshuffled channel informations such as the channel under the new connection status, carrier waves, and the channel configuration information of reshuffling is broadcast to terminal equipment by system message.

Usually only under the CELL-DCH state, terminal equipment can receive the data that network side sends by HS-DSCH.In order to improve the transfer rate that is mapped to the data on the FACH, relevant a kind of enhancing CELL_FACH state of proposing in the proposition HSPA evolution system, this strengthens under the CELL_FACH state, on the up direction, terminal equipment still can use the RACH channel to upload data, and on the down direction, former FACH is replaced by HS-DSCH, therefore, the lasting channel of monitoring of terminal equipment is HS-DSCH.Further specify, because FACH is replaced by HS-DSCH, therefore, transmission bearer on the Iub interface user face of this HS-DSCH correspondence no longer is the dedicated transmissions carrying, and the network address of the transmission bearer of this HS-DSCH and correspondence thereof need dispose in the Physical Shared Channel reconfiguration course of sub-district establishment stage.

Realize for convenient, and consider that the block size that strengthens under the CELL-FACH state is less relatively, relevant regulations is pointed out, in the HSPA evolution system, can be even terminal equipment possesses from being based upon the ability of a plurality of HS-DSCH reception data on the different carrier, but strengthening under the CELL-FACH state, only allowing terminal equipment to receive data from the single HS-DSCH of single carrier wave correspondence.

In addition, because in the existing communication system, RACH channel and FACH common signal channel only are based upon on the main carrier, if strengthen under the CELL_FACH state, only allow terminal equipment to use the channel that is based upon on the main carrier, then can limit the number of users that strengthens under the CELL-FACH state dramatically, therefore, relevant proposal is pointed out, the terminal equipment that allows to strengthen under the CELL-FACH state uses auxilliary carrier wave to carry out transfer of data, correspondingly, allow RACH is based upon on the auxilliary carrier wave, the HS-DSCH that carries former FACH data also can be based upon on the auxilliary carrier wave.

Owing to disposed the different RACH that are based upon respectively on main carrier and the different auxiliary carrier wave, and be based upon different HS-DSCH on main carrier and the different auxiliary carrier wave respectively, and strengthen under the CELL-FACH state, terminal equipment can only use a single carrier to send the RACH data, and can only use a single carrier to receive the HS-DSCH data, therefore, terminal equipment is before initiating access at random, need from a plurality of RACH, select a RACH with the transmission upstream data, and need from a plurality of HS-DSCH, select a HS-DSCH to monitor the data that network side issues.Similarly, owing to strengthen under the CELL_FACH state, the dedicated transmissions carrying that is exclusively used in a terminal equipment is no longer set up by Iub interface in RNC and base station, therefore, strengthen under the CELL-FACH state, RNC or base station will be difficult to distinguish the data that receive from RACH and belong to which terminal equipment, and which HS-DSCH the HS-DSCH that is difficult to the identification terminal equipment monitoring equally is, be difficult in other words adjudicate to send data to the terminal equipment of appointment by which HS-DSCH.

Therefore, on main carrier, one or more auxilliary carrier wave, set up different RACH if allow, or the HS-DSCH of replacement FACH, then strengthen under the CELL-FACH state, because of prior art does not provide transfer resource how to arrange to distribute to this terminal equipment between terminal equipment and the network side, cause being difficult to realizing communicating by letter between terminal equipment and the network side.

Carry out alternately step 603, RNC and base station, the network address of transmission bearer on agreement and the storage Iub interface user face.

The network address of a transmission bearer can perhaps, may be shared by a plurality of channel by a channel special use.

The network address of transmission bearer is disposed by network side on the Iub interface user face, can be disposed by RNC or base station.In RNC or the base station, after a side is provided with the network address of transmission bearer, need the set network address is notified to the opposite end, store the network address of transmission bearer by both party.

Enumerating the example of network side configuring transmission carrier, is S as the address set for the transmission bearer of the up channel i of carrier wave a configuration ₁, for the address set of the transmission bearer of the up channel j of carrier wave b configuration is S ₂, S set ₁Or S set ₂In element be different address informations.The address of a transmission bearer can be by under the situation of a channel special use, S ₁And S ₂Between common factor be not empty, i.e. S ₁And S ₂In have identical element; The address of a transmission bearer is by under the situation of a plurality of Channel Sharing, S ₁And S ₂Between common factor be empty.

Above-mentioned steps 601 is to step 603, by the mapping relations between RNC configurating channel and the corresponding carrier wave, and mutual by RNC and base station, on the Iub interface chain of command, make RNC and base station all can identify different channels and set up the carrier wave of this channel.Correspondingly, for making the base station can be under the control of RNC, send data by channel appointed to terminal equipment, and for to make the base station when the user data that will receive reports RNC, inform these data of RNC from which bar channel and with which carrier wave receive, on the Iub interface user face, need between RNC and the base station to notify which the transfer resource of the other side's carrying user data is, promptly need the carrier wave of carrying user data is indicated to the opposite end.

In the embodiment of the invention, based on the address of a transmission bearer by first kind of situation of a channel special use, perhaps the address of a transmission bearer is by second kind of situation of many Channel Sharing, and corresponding different situations has proposed transfer resource indicating mode on the different Iub interface user faces.

For first kind of situation, because the address of transmission bearer is the specific address, therefore, promptly can determine to use the upstream or downstream channel and the corresponding carrier wave of this address based on the network address of this transmission bearer, thereby indicating mode can be, utilize the network address that disposes the dedicated transmissions carrying of pairing transmission bearer configuration in advance for up channel, indicate up channel.The indicating mode of down channel is similar, promptly utilizes the network address that disposes the dedicated transmissions carrying of pairing transmission bearer configuration in advance for down channel, indicates down channel.Can carry out above-mentioned steps 601 during the step 603 between RNC and the base station, on the one hand correlation map is concerned that indication information indicates to the base station by RNC, RNC or base station can and specify the corresponding relation between the mapping relations to indicate to the opposite end with this address behind the network address of transmission bearer that is a special use of channel configuration on the one hand.

Because the address of a transmission bearer is shared by many channels, therefore, the address of a transmission bearer no longer can be used in the carrier wave of distinguishing different channels and setting up this channel, is applicable to that the indicating mode of first kind of situation no longer is applicable to second kind of situation.For second kind of situation, the embodiment of the invention provides, and being used on the Iub interface is set carry the data frame format of user data, and is provided for indicating the carrier wave indication information of the transfer resource of carrying user data in this data frame format.

The embodiment of the invention provides the way of two kinds of carrier wave indication information indication carrier wave relevant informations.

Way one: in the embodiment of the invention, in the set data frame format, the carrier wave indication information can be designated as the carrier index value.Before interactive user data between network side and the terminal equipment, by RNC or base station configuration and store the protocol value of carrier frequency and the corresponding relation between the index value, and can set up in process or Common transport channel reconfiguration course or the Physical Shared Channel reconfiguration course as Common transport channel on the Iub interface chain of command, the indication information of this corresponding relation is notified to the opposite end, stores by the opposite end.As the protocol value that disposes carrier wave is 10087,10056,10052, and the then corresponding protocol value that is provided with is that the index value of 10087 carrier wave is 0, and the index value that protocol value is set is 10056 carrier wave is 1, and the index value that protocol value is set is 10052 carrier wave is 2.Then, if if carrying the carrier index value in the upstream or downstream Frame is 1, the protocol value of then representing the carrier wave of this upstream or downstream channel correspondence is 10056.Correspondingly, RNC or base station can be known the carrier wave of this Frame of carrying based on this carrier index value, and based on carrier wave and the mapping relations that are based upon the channel on this carrier wave, know the channel of this Frame of carrying, up channel as this Frame of indication carrying in this Frame, then RNC can be according to the binding relationship between up channel and the down channel in the transfer resource indication information, find corresponding down channel, and the control base station sends user data by this down channel, promptly in Frame, indicate the down channel of this Frame of carrying, the base station receives after this Frame can know by which down channel to send data to terminal equipment.

Way two: in the embodiment of the invention, in the set data frame format, the carrier wave indication information also can directly be designated as the carrier frequency protocol value.Then in this way two, no longer need and store the protocol value of carrier frequency and the corresponding relation between the index value by RNC or base station configuration, but can be directly in Frame the frequency information of the carrier wave of this Frame of indication carrying, as carrier protocol value up or that down channel is corresponding is 10080, directly carrier frequency protocol value 10080 is being carried in the Frame of up channel or down channel.Correspondingly, RNC or base station can be known the carrier wave of this Frame of carrying based on this carrier index value, and based on carrier wave and the mapping relations that are based upon the channel on this carrier wave, know the channel of this Frame of carrying.
