As shown in Figure 3, the method that the information that the embodiment of the invention provides sends and obtains comprises:

Step 301, radio network controller (Radio Network Controller, whether RNC) monitor ability and change by the channel code of determining UE.

In the present embodiment, the channel code of UE is monitored ability and can be embodied by the version of UE, and for example: if the version of UE is R5 or R6, then the channel code monitoring ability of this UE be a channel code in can only the monitor channel sign indicating number tabulating; If the version of UE is R7, then the channel code monitoring ability of this UE is for monitoring the whole channel code in the HS-SCCH channel code tabulation under the 64QAM configuration; If the version of UE is R8, then the channel code monitoring ability of this UE is for monitoring the channel code in the tabulation of the HS-SCCH channel code under all categories and pattern among the HS-DSCH.

In the present embodiment, the channel code of UE monitoring ability can change in both cases:

1, to Target RNC, the version of source RNC and Target RNC is different from source RNC static migrating for UE, the UE channel code monitoring ability change after causing indirectly moving.

For example: if the source RNC version that UE inserts is R6, the version of UE is R8, so at Radio Resource control (Radio Resource Control, RRC) connect establishment stage, though UE sets up request message (RRC connection request) and/or Radio Resource at Radio Resource and sets up that to finish the version information that carries in the message (RRCconnection setup complete) be R8, but, because the version of source RNC is R6, so source RNC can only parse its highest version R6 that supports, that is: source RNC thinks that the version of UE is R6, when static migrating takes place for described UE---when source RNC is moved to Target RNC, if the version of Target RNC is R8, then this moment, Target RNC determined that the channel code monitoring ability of UE changes, particularly, in the present embodiment, if Target RNC receives the migration request message that source RNC sends, then determine the channel-monitoring ability change of UE.

Further, for guarantee Target RNC accurately the channel code of the UE after the informing base station migration monitor ability (version number), in the present embodiment, if the version of source RNC and Target RNC is identical, version as source RNC and Target RNC is R6, then after the migration request message that receives source RNC transmission, Target RNC is also determined the channel code monitoring ability information change of UE.

2, UE initiatively changes the channel code monitoring ability of self.

From the R7 version, UE can initiatively change the physical capability of self, and wherein, described physical capability comprises channel code monitoring ability.If UE initiatively changes the channel code of self and monitors ability, initiatively the version of self is changed to R8 by R7 as UE, perhaps change to R7 by R8, then UE can initiatively upgrade indication to the RNC reporting subdistrict, at this moment, RNC receives described cell update indication, and determines the channel code monitoring ability information change of described UE according to this cell update indication.

Certainly, more than two kinds of situations only be concrete for example, can not constitute the embodiment of the invention and limit, in the use of reality, the channel code of UE is monitored ability and can also be changed in other cases, RNC can determine that whether the channel code monitoring ability of UE changes, and, does not give unnecessary details every kind of situation one by one herein at different situations.

Step 302, RNC obtains UE channel code after changing and monitors ability information.

In the present embodiment, when RNC in thestep 301 determines the channel code monitoring ability change of UE, RNC can initiate the UE capability query, to UE transmitting capacity inquiry request message, UE receives described capability query request message, and channel code that will be after changing monitors ability information (in the present embodiment for after changing version number) and sends to RNC by query response message, and RNC receives described query response message, obtains UE channel code after changing and monitor ability information from this query response message.

Table 1:

The cell title	Exist	Scope	The cell type parameter	Language description	Importance	The importance of distributing
							The UE ability information		??0..1			Be	Ignore
＞support that duplex is time-multiplexed	Optional
							Relevant information
The relevant information of the duplexing frequency division multiplexing of＞support	Optional
							??＞UE?without?HS-SCCH??constraint?indicator	Optional		??9.2.2.XX		Be	Ignore

Wherein, described UE without HS-SCCH constraint indicator cell can be got two values: activate (ALLowed), the version of expression UE is R8, and channel code monitoring ability is for monitoring the channel code in the tabulation of the HS-SCCH channel code under all categories and pattern among the HS-DSCH; Deexcitation (Not-Allowed), the version of expression UE is R5, R6 or R7, channel code monitoring ability be can only the monitor channel sign indicating number a channel code in the tabulation, perhaps can monitor HS-SCCH channel code under the 64QAM configuration whole channel code in tabulating;

In order to save transfer resource, in the present embodiment, if the version of UE is R5, R6 or R7, also can not carry UE without HS-SCCH constraint indicator cell in the radio link reconfiguration message, at this moment, can give tacit consent to the UE version after changing that radio link reconfiguration message carries is R5, R6 or R7;

Certainly, in the use of reality, RNC can also carry UE channel code after changing by other modes and monitor ability information in the message that sends to the base station, every kind of situation is not given unnecessary details one by one herein.

Step 304, base station receive the message of carrying UE channel code monitoring ability information after changing that RNC sends.

Step 305, base station are obtained UE channel code after changing and are monitored ability information from the message that describedstep 304 receives.
