Abstract
The present invention discloses a realizing method of a cell broadcasting service (CBS), which comprises the steps: a cell broadcasting message is sent from a core network to an access network; after the cell broadcasting message which is sent by the core network is received by the access network, the cell broadcasting message is sent to an integral target cell by a common service channel; meanwhile, the access network judges whether user equipment (UE) which is in the states of connecting modes of cell-dedicated channel (CELL-DCH) and cell-forward access channel (CELL-FACH) exists in the integral target cell or not, if true, then a cell broadcasting content to be sent is placed in a wireless resource control message for bearing a cell broadcasting service by the access network, and is sent to the UE in the states of the connect modes of the CELL-DCH and the CELL-FACH by a dedicated control channel, else a cell broadcasting sending procedure is finished. The method causes that the UE in the states of the connect modes of the CELL-DCH and the CELL-FACH can also receive a CBS service, and further, the CBS service is provided for the UE in various states in the same cell.
Description
Technical field
The present invention relates to a kind of Zone in the mobile radio communication, be meant a kind of implementation method of cell broadcaste service especially.
Background technology
In the third generation (3G) mobile communications network, cell broadcaste service (CBS) is a kind of point-to-multipoint service, the data one-way transmission of all or part subscriber equipment (UE) this business is finished from the CBC of core net (CN) (CBC) to a certain geographic area.Here, described geographic area is meant the set of physical area.
Under the Radio Resource of 3G control (RRC) agreement, exist a RRC to be connected between subscriber equipment (UE) and the UTRAN, be equivalent to UE and in UTRAN, register, at this moment, if UTRAN thinks then that to UE distribution wireless network identification UE is in idle pulley; Distributed an interim wireless network identification if UTRAN is UE, but do not given the UE distributing radio resource, UTRAN can " see " UE under the connection status, thinks that then UE is in connection mode.According to the employed channel of UE, described connection mode is divided into following four kinds of connection status:
1) sub-district-paging channel (CELL-PCH) state: UE can not use Random Access Channel (RACH) under this state, only can adopt periodically monitors (PCH) of discontinuous demodulation (DRX), can not transport service.UE will carry out cell update after moving out current area, and therefore, UTRAN knows clearly which sub-district the UE under this state is in.
2) registration-paging channel (URA-PCH) state: with the CELL-PCH state class seemingly, UE can not use RACH under this state, only can adopt DRX cycle monitors (PCH), can not transport service.UE will carry out the URA renewal after moving out current UTRAN Acceditation Area (URA), and therefore, UTRAN knows clearly which URA the UE under this state is in.This state is used to avoid UE frequent cell update when cell boarder under the CELL-PCH state, and it monitors that paging method is the same.
3) sub-district-forward access channel (CELL-FACH) state: can use RACH, and continuous monitoring forward access channel (FACH), can carry the Packet Service of some low rates.UE will carry out cell update after moving out current area, and therefore, UTRAN knows clearly which sub-district the UE under this state is in.
4) sub-district-dedicated channel (CELL-DCH) state: this state is that UE has distributed dedicated channel, and three states in front are not all given the UE assigned with dedicated channel, and can support multiple business under this state.
More than in four kinds of states, CELL-PCH state and URA-PCH state are discontinuous demodulation state.Along with the variation of using, can shift mutually between these several connection status.When the business transmission finishes or does not have transfer of data for a long time, network will discharge the respective physical channel resource and forward the CELL-PCH state to or the URA-PCH state, but, high layer conversation between UE and the UTRAN keeps always, that is to say, corresponding RAB (RAB) does not discharge, and when UE carried out the business transmission again, UTRAN can make response at once.
At present, stipulate in the 3G agreement: the UE that only is in idle pulley and is in CELL_PCH under the connection mode, two states of URA_PCH could receive the information on the CTCH Common Traffic Channel (CTCH), and in the prior art, cell broadcast messages is dealt into UTRAN from CN; Then, UTRAN sends to whole sub-district by the CTCH channel, Figure 1 shows that the quick-reading flow sheets schematic diagram that cell broadcast messages sends.In other words be exactly that according to the definition of present agreement: the CBS business only can offer the UE that is in idle pulley and is in CELL_PCH under the connection mode, URA_PCH state and use.So, be in the UE of CELL_DCH and CELL_FACH state under the connection mode, or the UE that is in talking state just can not receive the CBS business, this obviously makes the CBS business have certain limitation, is extremely irrational.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of implementation method of cell broadcaste service, make to be in that the UE of CELL_DCH and CELL_FACH state also can receive the CBS business under the connection mode, and then provide CBS business for the UE that is in various states in the same sub-district.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of implementation method of cell broadcaste service may further comprise the steps:
A. core net sends cell broadcast messages to Access Network;
B. after Access Network is received the cell broadcast messages of core net, send to whole Target cell by CTCH Common Traffic Channel; Simultaneously, Access Network judges whether there is the UE that is under connection mode CELL-DCH state and the CELL-FACH state in the Target cell according to the private resource state, if having, and execution in step c; Otherwise, finish the Cell Broadcast CB transmission flow;
C. the Access Network Cell Broadcast CB content that will send is put into the RRC message that is used for carrying cell broadcaste service, sends to the UE that is in connection mode CELL_DCH and CELL_FACH state by Dedicated Control Channel.
Wherein, described RRC message comprises message identifier (ID) at least and is used to place the message content part of the Cell Broadcast CB content that will send.
This method further comprises: after UE receives described RRC message, therefrom extract corresponding Cell Broadcast CB content, carry out follow-up cell broadcast messages and handle.
Therefore, cell broadcaste service implementation method provided by the present invention, increase by one with the professional relevant RRC message of CBS, and by being in Dedicated Control Channel (DCCH) transmission that UE can monitor under CELL_DCH and the CELL_FACH state, make UTRAN directly to send the Cell Broadcast CB content to be under connection mode CELL_DCH or the CELL_FACH state UE via the DCCH channel, thereby strengthen and improve the professional ability of CBS.For the user, the UE that is under any state can both receive the CBS business, and the CBS business more can be accepted by user and service provider.
Description of drawings
The simple procedure schematic diagram that Fig. 1 sends for cell broadcast messages;
The schematic flow sheet that Fig. 2 sends for cell broadcast messages among the present invention.
Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Because the UE that is under CELL_DCH and the CELL_FACH state can monitor Dedicated Control Channel (DCCH), therefore, basic thought of the present invention is: the Cell Broadcast CB content of UE under sending at CELL_DCH and CELL_FACH state on the DCCH channel, specific practice is exactly the RRC message that a special carrying cell broadcaste service is set, and the content of Cell Broadcast CB is placed on the UE that directly sends in this RRC message under CELL_DCH and the CELL_FACH state.
For all UE in each sub-district, what wireless system was that the UE under CELL_PCH, the URA_PCH state distributes is public resource, what distribute for the UE under CELL_DCH and the CELL_FACH state is private resource, and UTRAN can be known the UE that is under the private resource state automatically.That is to say, UTRAN does not know which UE is in the CELL_PCH of connection mode, URA_PCH state, but know which UE is in the CELL_DCH and the CELL_FACH state of connection mode, therefore, UTRAN can initiatively send broadcasted content to the UE that is in CELL_DCH and CELL_FACH state by the DCCH channel.
As shown in Figure 2, finishing the implementation procedure that Cell Broadcast CB sends among the present invention may further comprise the steps:
Step 200:CN sends cell broadcast messages to UTRAN;
After step 201~203:UTRAN receives the broadcast of CN, send to whole Target cell by the CTCH channel earlier; Simultaneously, UTRAN judges whether there is the UE that is under connection mode CELL_DCH and the CELL_FACH state in the Target cell, if have, then the content of Cell Broadcast CB is placed on the message content of the RRC message that is used for carrying cell broadcaste service, sends to the UE that is in connection mode CELL_DCH and CELL_FACH state by the DCCH channel; Otherwise, just finish the transmission flow of Cell Broadcast CB.Wherein, described RRC message pre-defines, and contains message identifier (ID) and message content part at least, and message content part is exactly to be used for placing the Cell Broadcast CB content that will send.
UE therefrom extracts corresponding broadcasted content after receiving described RRC message, by UE in the prior art processing procedure of broadcast is finished subsequent treatment then.In fact, for the UE that is in different mode, content and the follow-up handling process of obtaining Cell Broadcast CB from Access Network all are identical, just from the Access Network to the different mode under the UE transmission channel difference that broadcasted content adopted.
In above-mentioned steps, in fact, it is side by side that UTRAN sends broadcasted content this two operations to whole Cell Broadcast CB and UTRAN by the UE of DCCH under CELL_DCH and CELL_FACH state by CTCH, successively carry out or carry out simultaneously can, and whose whose back sequence independence earlier.
In the CBS business of method of the present invention applicable to various 3G (Third Generation) Moblie network systems, in a word, the above is preferred embodiment of the present invention only, is not to be used for limiting protection scope of the present invention.
