Description
Technical field
The present invention relates to the communications field, and more particularly, relate to a kind of Radio Resource control (RRC) state transition method and system, it can change RRC status fast.
Background technology
In mobile communication system, forward access channel (Forward Access Channel, FACH) be the down channel that is used to transmit low volume data, simultaneously also be to be used for the downlink transmission channel that sends control information to the terminal that is positioned at a certain sub-district, in addition, can also in FACH, send business datum.
In addition, (Paging Channel PCH) is the downlink transmission channel that is used to send the data relevant with paging to paging channel, and it is used for the initialization of network and terminal.One of purposes of PCH is to initiate voice call to terminal, and for example, network uses the PCH of the sub-district in the terminal region to send beep-page message to terminal.Terminal must can both receive paging information in whole cell range, therefore, the design of PCH affects the power consumption of terminal under standby mode: the gating message times that terminal is adjusted the receiver monitoring is few more, and the duration of end cell under standby mode is just long more.Terminal need monitor Page Indication Channel (Paging Indicator Channel, PICH) so that need to determine whether the paging receiving channel data.
Two kinds of fundamental modes of subscriber equipment (such as, travelling carriage) are idle pulley and connection mode.Wherein, so-called idle pulley is meant that subscriber equipment is in holding state, the state when still not having professional the existence; And so-called connection mode, be meant subscriber equipment and radio network controller (Radio Network Controller, (Radio Resource Control RRC) connects state when setting up to have finished Radio Resource control between RNC), at this moment, subscriber equipment has quartered in the sub-district.And, under connection mode, subscriber equipment has 4 kinds of states, is respectively CELL_DCH (CELL _ DCH) state, CELL_FACH (sub-district _ forward access channel) state, CELL_PCH (cell _ paging channel) state, URA_PCH (universal land radio access web registration area _ paging channel) state:
The CELL_DCH state: subscriber equipment has Dedicated Control Channel (DCCH) and Dedicated Traffic Channel (DTCH), and utilizes special-purpose (or sharing) channel to communicate status of processes;
The CELL_FACH state: subscriber equipment has DCCH and DTCH, can need not assigned with dedicated channel receiving data on the FACH and send data on RACH, transmits condition of information on public FACH/RACH channel;
The CELL_PCH state: subscriber equipment can not use DCCH and DTCH, cannot receive and send data, only the state the during paging indicating message on down direction listening paging indicating channel PICH channel; Only to send CELL Update message to RNC.
The URA_PCH state: subscriber equipment can not use DCCH and DTCH, cannot receive and send data, only the state when down direction is intercepted paging indicating message on the PICH channel; Only to send URA Update or Cell Update message to RNC.
Under connection mode, the conversion of status of user equipment is to be decided by the unlimited resources management and the dispatching algorithm of radio network controller according to oneself.When subscriber equipment need be set up calling, it sends, and message was set up in the RRC connection and request foundation is professional, and the infinite network controller determines the residing RRC state of subscriber equipment according to the type of service of current wireless resource status and subscriber equipment.
Usually, when subscriber equipment carried out CS territory professional, the radio network controller assigned with dedicated channel was given subscriber equipment, and subscriber equipment is in the CELL_DCH state; When subscriber equipment carries out the PS territory when professional, if flow is less, radio network controller assigned with dedicated channel not then, and UE is placed the CELL_FACH state, on the contrary, and if flow is bigger, radio network controller assigned with dedicated channel then.Generally, in the business of PS territory, subscriber equipment may not have the up-downgoing transfer of data long period, radio network controller can be CELL_PCH or URA_PCH with the state exchange of subscriber equipment so, when being converted to CELL_PCH or URA_PCH state by CELL_FACH or CELL_DCH, subscriber equipment can not transmit and receive data and signaling (except sending Cell Update and URAUpdate signaling), be merely able to monitor Page Indication Channel (Paging Indicator Channel, information PICH).The main purpose that subscriber equipment remains on the CELL_PCH state be for save subscriber equipment with electric consumption (because only needing to receive the PICH channel), and the connection between maintenance RRC connection and the same core net (CN), accelerate the time that radio bearer is set up and transfer of data is recovered.
In addition, the proposition of URA_PCH state is in order further to reduce the signaling message stream that cell update brought, if subscriber equipment does not have Business Stream for a long time, then to enter this state.URA generally includes a plurality of sub-districts, when subscriber equipment is in the URA_PCH state, can not start cell updating course if cell change URA is constant, thereby saves Radio Resource.Which kind of mode of operation subscriber equipment is in is transparent for core net.
In existing 3GPP agreement,,, at first need state exchange with UE to CELL_FACH or CELL_DCH if network will send data to UE or other reasons when UE is in CELL_PCH, URA_PCH state following time.Hereinafter with reference to Fig. 1 and Fig. 2 above-mentioned RRC state conversion process is described.Wherein, Fig. 1 is the signaling process figure according to the RRC state exchange of being initiated by network of correlation technique; Fig. 2 is the flow chart according to the RRC state exchange of being initiated by network of correlation technique.
At first, in step S202, UTRAN (UMTS system ground Radio Access Network) sends the paging indication to UE in Page Indication Channel (PICH), and indication UE goes up paging receiving message to corresponding paging channel (PCH); Afterwards, in step S204, UTRAN in PCH to UE transmission types 1 beep-page message; In step S206, corresponding to above-mentioned beep-page message, UE sends cell update message to UTRAN; In step S208, UTRAN sends the cell update acknowledgement message to UE, and wherein carries state exchange indication (indication UE is transformed into corresponding RRC state) and relevant configuration parameter; Next, in step S210, UE according to the indication of cell update acknowledgement message with the RRC state exchange to designated state, and dispose local parameter according to the indication of wherein configuration information; UE in step S212, sends mobile message acknowledge message or other message to UTRAN after finishing configuration, reply.
In addition, if UE is transformed into CELL_FACH from CELL_PCH/URA_PCH, then the configuration information that carries in the cell update acknowledgement message may comprise: RRC Status Flag, new C-RNTI (Cell Radio Network Temporary Identifier/Identity, Cell-RNTI symbol) (may also comprise U-RNTI (universal terrestrial access network temporary identifier)), frequency information, radio bearer information etc.Generally speaking, not configuration frequency information and radio bearer information in this message are because it is pre-configured before UE enters the CELL_PCH/URA_PCH state.
If UE is transformed into CELL_DCH from CELL_PCH/URA_PCH, then the configuration information that carries in the cell update acknowledgement message may comprise: new C-RNTI (may also comprise U-RNTI), frequency information, radio bearer information, up-downgoing transmitting channel information, up-downgoing physic channel information etc.
