Description
Technical field
The present invention relates to moving communicating field, and more particularly, relate to a kind of channel arrangement method.
Background technology
At moving communicating field, WCDMA (Wideband Code Division MultipleAccess, Wideband Code Division Multiple Access (WCDMA)) system provides the access and the transmission in broadcasting (BC) territory, Circuit Service (CS) territory and Packet Service (PS) territory.At present, the BC territory provides broadcasting in the system, and the CS territory provides the access and the transmission (mainly being voice service) of circuit-switched service, and the PS territory provides the access and the transmission (mainly being the IP message) of Packet Service, and the structure of WCDMA system as shown in Figure 1.
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), CELL_FACH (sub-district _ forward access channel), CELL_PCH (cell _ paging channel), 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 it will enter this state, universal land radio access web registration area (Universal Terrestrial RadioAccess Network Registration Area, URA) comprise a plurality of sub-districts usually, when subscriber equipment is in the URA_PCH state, if cell change and URA is constant, then can not start cell updating course, thereby save Radio Resource.Which kind of mode of operation subscriber equipment is in is transparent for core net.
In existing 3GPP standard, after UE initiates PS territory business, owing to temporarily do not have data to transmit or based on always online purpose, UE forwards under the situation of CELL_FACH state, UE initiate the CS territory calling process as shown in Figures 2 and 3.Hereinafter with reference to accompanying drawing this process is described.
Wherein, Fig. 2 is that subscriber equipment is initiated CS territory calling signaling flow chart under the CELL_FACH state, and Fig. 3 is that subscriber equipment is initiated the process chart that call out in the CS territory under the CELL_FACH state.
At first, in step S302, UE sets up RRC with RNC and is connected, and is in the CELL_FACH state; In step S304, UE sends initial directly message transfer to RNC, and wherein, this message is used for call setup reason (this initiates audio call), and carries Non-Access Stratum (NAS) information; In step S306, RNC sends initial UE message to CN, and above-mentioned NAS information is transmitted to CN; Next, in step S308, RNC sends radio bearer reconfiguration message to UE, UE is switched to the CELL_DCH turntable, wherein, carry configuration information in this message, but only configuration is for the dedicated transmission channel and the DPCH resource of SRB (Signaling Radio Bearer) use, and SRB is mapped on the dedicated transmission channel;
Then, in step S310, UE comes configure transport channel and physical channel in response to radio bearer reconfiguration message according to the configuration information in this message, and to do physical channel synchronous with Node B, afterwards, sends radio bearer to RNC and reshuffles and finish message; In step S312, UE and CN carry out authentication;
Next, in step S314, CN sends RAB (RAB) configuration request message to RNC, wherein includes the relevant configuration information of the radio bearer that is used for service data transmission of needs foundation; In step S316, in response to the RAB configuration request message, RNC sends radio bearer to UE and sets up message, and wherein include radio bearer configuration information, in this step, also need to dispose the transmission channel and the physical channel resources of these radio bearer needs, because the physical channel resources of setting up in this step is different resources with what set up among the step S308, therefore use the method for synchronization to carry out radio bearer and set up, systematic comparison is simple, and Radio Resource can not wasted; In step S318, UE sets up message in response to radio bearer, comes radio bearer, transmission channel and physical channel according to wherein configuration information, and to do physical channel synchronous with Node B;
Afterwards, in step S320, UE sends radio bearer foundation to RNC and finishes message, and in step S322, finishes message in response to this radio bearer foundation, and RNC sends the RAB assignment response message to CN.
From the above description of UE according to correlation technique being initiated the process of calling out in the CS territory under the CELL_FACH state as can be seen, when UE sends initial directly message transfer behind RNC, RNC will switch to CELL_DCH with UE earlier according to the call setup reason, but this moment RNC and do not know the particular type that CS that UE will set up calls out, in step S308, be the pre-configured physical resource of radio bearer in CS territory so have no idea, setting up the mode that can only adopt the synchronous radio carrying to set up in the process at the radio bearer of subsequent step S316 like this (is that UE and NodeB need switch to new radio bearer in the time of both sides' appointment, even both sides have finished synchronously), increased calling establishment time delay like this, if and the employing asynchronous system is set up radio bearer, the processing of Node B and UE will be very complicated, this will cause waste of radio resources, and further cause systematic function to descend.
In addition, Fig. 4 is that UE according to correlation technique initiates CS territory call signalling flow figure under idle condition.As shown in Figure 4, when the UE that is in idle condition initiates the calling of CS territory, set up in the process, will set up SRB (Signaling Radio Bearer), and after receiving initial directly message transfer, will carry out the authentication process in the RRC connection.And during this period, the process that authentication and radio bearer are set up is that serial is carried out, and has therefore increased the delay of call setup.
