Embodiment
In order to make the object of the invention, technical scheme and advantage clearer, describe the present invention below in conjunction with accompanying drawing and specific embodiment.
Method provided by the invention mainly comprises: the terminal is according to the terminal capability class information from RNC; Perhaps set up the reception situation of message according to radio bearer; Confirm the terminal capability class information that the base station gets access to, and the ability rating that use at this terminal is set according to the terminal capability class information of confirming.
Below in conjunction with specific embodiment said method is described in detail.
Embodiment one,
The terminal capability class information that the base station gets access to is confirmed according to the terminal capability class information from RNC in the terminal.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 the terminal.
In this step, when RNC sends to the terminal with the terminal capability class information, can directly send to the terminal, also can at RNC after the terminal capability class information is sent to the base station, redispatch to the terminal by the base station.
RNC can comprise following several kinds with the situation that the terminal capability class information sends to the base station:
When 1) service communication need be carried out with network in the terminal; Can initiate RRC connection Request to RNC; Only carry the 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 RRC connection Request, if the terminal is in the CELL_DCH state, then RNC came to send minimum terminal capability class information to the base station through setting up process to base station initiation Radio Link.In this case; When RNC gives the base station in the ability rating information of sending minimum terminal capability class information or agreement; The ability rating information of this minimum terminal capability class information or agreement of also sending is given the terminal, perhaps is transmitted to the terminal by the base station through physical layer control channel.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, the terminal just can confirm 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 accomplished; RNC sends RRC to the terminal and connects foundation (RRC connection setup) message; Accomplish after the configuration according to RRC connection setup message at the terminal, returns the RRC connection setup complete message of carrying physical end ability rating information to RNC.This has just accomplished the RRC connection procedure, the terminal just can and core net between mutual Non-Access Stratum (NAS) signaling message, accomplish the Signalling exchange of NAS layer after, get into 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 through radio link reconfiguration message; And terminal capability class information that should reality sends to the terminal, or is transmitted to the terminal by the base station through physical layer control channel.Like this, the terminal just can confirm 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 the 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 send to the base station with minimum terminal capability grade, agreement ability rating or actual terminal capability grade through Frame Protocol (FP) Frame or control frame, at this moment; The terminal capability class information that RNC will send to the base station simultaneously directly sends to the terminal, perhaps is transmitted to the terminal by the base station through physical layer control channel.Like this, the terminal just can confirm 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 through physical channel ability cell (Physical channel capability IE).
Step 102: after the base station receives the terminal capability class information of RNC transmission, be directed against the transfer of data at this terminal according to this terminal capability class information.
Step 103: after the terminal receives the terminal capability class information from RNC, confirm 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 the 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; The terminal can also further combine self residing RRC connection status that the ability rating of self is set; Be specially: strengthen the CELL-FACH state or strengthen the CELL-PCH state if the terminal is in; Because it is support expanded HS-DSCH ability rating (HS-DSCH physical layer category extension) not, can not consider this expansion HS-DSCH ability rating.
Embodiment two,
The reception situation of message is set up according to radio bearer in the terminal, confirms 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 at terminal; Minimum terminal capability grade or agreement terminal capability grade are sent to the base station; After receiving the RRC connection setup complete message at terminal, the terminal capability grade of reality is sent to the base station.
Because the 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 identical with prior art, repeats no more.
