Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
Method provided by the invention mainly comprises: terminal is according to the terminal capability class information from RNC, perhaps set up the reception situation of message according to radio bearer, determine the terminal capability class information that the base station gets access to, and the ability rating that this terminal is used is set according to the terminal capability class information of determining.
Below in conjunction with specific embodiment said method is described in detail.
Embodiment one,
Terminal is determined the terminal capability class information that the base station gets access to according to the terminal capability class information from RNC.The method flow diagram that Fig. 1 provides for the embodiment of the invention one, as shown in Figure 1, this method can may further comprise the steps:
Step 101:RNC is when sending to the base station with the terminal capability class information, and the terminal capability class information that also will send to the base station sends to terminal.
In this step, when RNC sends to terminal with the terminal capability class information, can directly send to terminal, also can at RNC after the terminal capability class information is sent to the base station, send to terminal again by the base station.
RNC can comprise the situation that the terminal capability class information sends to the base station following several:
When 1) terminal need be carried out service communication with network, can initiate RRC connectionRequest to RNC, only carry terminal among this RRC connection Request and whether supported the ability of HSPA or HSPA+ to indicate, do not had concrete terminal capability class information.After RNC received RRCconnection Request, if terminal is in the CELL_DCH state, then RNC came to send minimum terminal capability class information to the base station by setting up process to base station initiation Radio Link.In this case, RNC is in the ability rating information that sends minimum terminal capability class information or agreement during to the base station, the ability rating information that also sends this minimum terminal capability class information or agreement perhaps is transmitted to terminal by the base station by physical layer control channel to terminal.Wherein, this physical layer control channel can comprise: E-DCH absolute grant channel (E-AGCH) or High-Speed Shared Control Channel (HS-SCCH).Like this, terminal just can determine also what the terminal capability grade that the base station gets access to is, thereby adopts the terminal capability grade consistent with the base station.
2) after the Radio Link between RNC and the base station is set up and is finished, RNC sends RRC to terminal and connects foundation (RRC connection setup) message, terminal is finished according to RRC connection setup message after the configuration, returns the RRC connectionsetup complete message of carrying physical end ability rating information to RNC.This has just finished the RRC connection procedure, terminal just can and core net between mutual Non-Access Stratum (NAS) signaling message, finish the Signalling exchange of NAS layer after, enter the service bearer establishment stage.Set up in the process at service bearer, RNC can send actual terminal capability class information to the base station by radio link reconfiguration message, and terminal capability class information that should reality sends to terminal, or is transmitted to terminal by the base station by physical layer control channel.Like this, terminal just can determine also what the terminal capability grade that the base station gets access to is, thereby adopts the terminal capability grade consistent with the base station.
3) in the HSPA+ system, when if terminal is in cell forward access channel (CELL_FACH) state or cell paging channel (CELL_PCH) state, because not having the Radio Link of terminal-specific on the Iub interface between RNC and the base station sets up and reconfiguration message, therefore, RNC only can pass through Frame Protocol (FP) Frame or control frame with minimum terminal capability grade, agreement ability rating or actual terminal capability grade send to the base station, at this moment, the terminal capability class information that RNC will send to the base station simultaneously directly sends to terminal, perhaps is transmitted to terminal by the base station by physical layer control channel.Like this, terminal just can determine also what the terminal capability grade that the base station gets access to is, thereby adopts the terminal capability grade consistent with the base station.
This terminal capability class information can carry by physical channel ability cell (Physical channelcapability IE).
Step 102: after the base station receives the terminal capability class information that RNC sends, carry out transfer of data at this terminal according to this terminal capability class information.
Step 103: after terminal receives terminal capability class information from RNC, determine that the terminal capability class information that the base station gets access to is this terminal capability grade, and the ability rating of use is set according to this terminal capability class information.
Wherein, above-mentioned terminal capability grade can comprise: strengthen dedicated channel (E-DCH) ability rating and high-speed downlink shared channel (HS-DSCH) ability rating.
If the terminal capability class information that terminal receives from RNC is minimum terminal capability grade, it is minimum terminal capability grade that the ability rating that self uses then is set; If the terminal capability class information that receives from RNC is agreement terminal capability grade, the ability rating that self uses then is set is agreement terminal capability grade; Be actual terminal capability grade if receive, the ability rating that self the uses terminal capability grade as reality then is set from the terminal capability class information of RNC.
More preferably, terminal can also be provided with the ability rating of self further combined with self residing RRC connection status, be specially: strengthen the CELL-FACH state or strengthen the CELL-PCH state if terminal is in, because it does not support to expand HS-DSCH ability rating (HS-DSCH physical layercategory extension), can not consider this expansion HS-DSCH ability rating.
Embodiment two,
Terminal is set up the reception situation of message according to radio bearer, determines the terminal ability information that the base station gets access to.The method flow diagram that Fig. 2 provides for the embodiment of the invention two, as shown in Figure 2, this method can may further comprise the steps:
Step 201:RNC receives before the RRC connection setup complete message of terminal, minimum terminal capability grade or agreement terminal capability grade are sent to the base station, after receiving the RRCconnection setup complete message of terminal, the terminal capability grade of reality is sent to the base station.
Because terminal is carried terminal ability rating information in RRC connection setup complete message only, therefore, RNC only just can be known the terminal capability class information after receiving RRC connection setup complete message.This part is same as the prior art, repeats no more.
Step 202: terminal is determined the terminal capability class information that the base station gets access to according to the reception situation of radio bearer foundation (Radio bearer setup) message, and according to the terminal capability grade of determining the ability rating that this terminal is used is set.
This step can be specially: terminal is before receiving Radio bearer setup message, can think does not still have radio bearer to set up process, the practical capacity grade of terminal can not be known in the base station, the minimum terminal capability grade or the agreement terminal capability grade that only may adopt RNC to send, therefore, the ability rating unanimity of terminal in order to keep adopting also adopts minimum terminal capability grade or agreement terminal capability grade.After receiving Radio bearer setup message, can think that the base station sets up process by radio bearer, known actual terminal capability class information, therefore, the indicated moment of activationary time point that terminal can comprise in Radio bearer setup message, the terminal capability grade that beginning is actual.
After receiving Radio bearer setup message, if being in the CELL_DCH state and satisfying E-DCH, terminal sends condition, and perhaps terminal is in the CELL_FACH state and satisfies E-DCH and sends condition, and then terminal adopts actual E-DCH ability rating.If terminal is in the CELL_DCH state and satisfies the HS-DSCH condition of acceptance, perhaps terminal is in the CELL_FACH state and satisfies the HS-DSCH condition of acceptance, perhaps terminal is in the CELL_PCH state and has satisfied HS-DSCH condition of acceptance and terminal configuration H-RNTI, and then terminal adopts actual HS-DSCH ability rating.
More preferably, before receiving Radio bearer setup message, can specifically be divided into two kinds of situations:

If terminal does not receive the reconfiguration message of eating dishes without rice or wine, can think that then RNC does not send actual terminal capability class information by link reconfigure message to the base station, then terminal adopts minimum terminal capability grade or agreement terminal capability grade in order to be consistent with the base station.Concrete adopt minimum terminal capability grade still arrange the terminal capability grade according to system setting choose.
2) before terminal receives Radio bearer setup message, and terminal receives such as reconfiguration message of eating dishes without rice or wine such as physical channel reconfiguration message, radio bearer reconfiguration message or transmission channel reconfiguration message the terminal capability grade of then employing reality.
If terminal receives the reconfiguration message of eating dishes without rice or wine, illustrate that terminal sends to RNC with RRC connectionsetup complete message, and RNC has sent actual terminal capability class information by link reconfigure message to the base station, then terminal adopts actual terminal capability grade in order to be consistent with the base station.
In above-mentioned two embodiment, if being in the CELL_DCH state and satisfying E-DCH, terminal sends condition, and perhaps terminal is in the CELL_FACH state and satisfies E-DCH and sends condition, and then above-mentioned terminal capability class information is an E-DCH ability rating information.
If terminal is in the CELL_DCH state and satisfies the HS-DSCH condition of acceptance, perhaps terminal is in the CELL_FACH state and satisfies the HS-DSCH condition of acceptance, perhaps terminal is in the CELL_PCH state and has satisfied HS-DSCH condition of acceptance and terminal configuration H-RNTI, and then above-mentioned terminal capability class information is the HS-DSCH ability rating.
