Description

Call-establishing method and system
Technical field
The present invention relates to the communications field, and more particularly, relate to a kind of call-establishing method and system, it can be applied to the system such as WCDMA (Wideband Code DivisionMultiple Access, broadband CDMA).
Background technology
At moving communicating field, the 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) 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 RRM 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 radio 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.
Cell update (Cell Update) all might take place in the subscriber equipment that is under four kinds of states of connection mode, and the reason that subscriber equipment is initiated cell update may comprise: the sub-district gravity treatment, reenter service area, periodic cell update, Radio Link Failure, page response, transmitting uplink data or RLC (Radio Link Controller) irrecoverable property mistake takes place.
Initial directly transmission course is used for setting up signaling and connects on up link, also be used for transmitting on wave point initial high level (Non-Access Stratum) message.In user equipment side, when high level requires to set up a signaling connection subscriber equipment, will start initial directly transmission course.
With reference to Fig. 2 and Fig. 3 the process that the Access Network according to correlation technique makes a call to subscriber equipment is described below.
Wherein, Fig. 2 is the signaling process figure that the Access Network according to correlation technique makes a call to subscriber equipment (under CELL_PCH or URA_PCH state), and Fig. 3 is the process chart that the Access Network according to correlation technique makes a call to subscriber equipment (under CELL_PCH or URA_PCH state).
At first, in step S302, receive the message of certain UE as CN after, send beep-page message to RNC; In step S304, in response to this updating message, if subscriber equipment under CELL_PCH or URA_PCH state, then RNC sends paging Class1 message to UE on PCCH; Next, in step S306,, then on CCCH, send cell update message, start cell updating course to RNC if UE need initiate the service request of CN;
Afterwards, in step S308, RNC sends the cell update acknowledge message to UE, wherein carries to be used for UE sends information on DCCH C-RNTI; Subsequently, in step S310, in response to the cell update acknowledge message, UE sends UTRAN mobility confirmation to RNC on DCCH, afterwards, and in step S312, on DCCH, send initial directly message transfer, and wherein carry the Non-Access Stratum information of CN to RNC; At last, in step S314, in response to initial directly message transfer, RNC sends the initial user equipment message to CN, sets up RNC and is connected with signaling between the CN, and by this message Non-Access Stratum information is forwarded to CN.After this, authentication, safe mode and processes such as radio bearer foundation and session control can be arranged.
From above to according to the CN of correlation technique to UE makes a call the description of process as can be seen, send beep-page message from CN to RNC, the process that in the process of the initial directly message transfer of RNC transmission, needs to carry out a cell update to UE, therefore the interactive signaling flow process of eating dishes without rice or wine is too much, cause call delay to increase, and then reduced user experience.
Therefore, hope can provide a kind of call-establishing method and system, and it can reduce the time delay of calling user device effectively, thereby improves user experience.
Summary of the invention
Consider the problems referred to above and make the present invention.For this reason, the invention provides a kind of call-establishing method and system, it can reduce the time delay of calling user device effectively, thereby improves user experience, and can be applied to the system such as WCDMA.
According to an aspect of the present invention, provide a kind of call-establishing method.
