The base station resource management method provided by the invention is used for managing the base station resources of the WCDMA network with different capability level baseband processing single boards coexisting. When UE sends a radio resource control establishment request to RNC, the RNC generates physical layer requirement information according to a user terminal capability indication and an establishment reason carried in the radio resource control establishment request; when the RNC needs to send a wireless link establishment request to the NodeB, the generated physical layer requirement information is carried in the wireless link establishment request and sent to the NodeB, and the NodeB selects baseband processing single boards with different capability levels according to the physical layer requirement information.
In the base station resource management method of the present invention, the operation flow of the RNC is shown in fig. 1, and mainly includes the following steps:
The physical layer requirement information of the invention is at least one of HS-DSCH requirement indication and E-DCH requirement indication, the corresponding relation between the user terminal capability indication, the establishment reason and the physical layer requirement information is preset in the RNC according to the actual requirement, and the corresponding relation is stored in the RNC in the form of a table. Wherein, the corresponding relation between the user terminal capability indication, the establishment reason and the HS-DSCH requirement indication is shown in Table 1,
TABLE 1
As shown in table 1, the ue capability indication includes three kinds of information: absence (Not Present), support of HS-DSCH and support of HS-DSCH + E-DCH. The user terminal capability indication carried in each radio resource control establishment request sent by the UE to the RNC only comprises one of three information, if the user terminal capability indication is Not Present, the user terminal capability indication indicates that the information of the user terminal capability indication does Not exist in the radio resource control establishment request sent by the UE; if the user terminal capability indication is HS-DSCH support, indicating that the UE can support HS-DSCH; if the user terminal capability indication is HS-DSCH + E-DCH supported, it indicates that the UE can support HS-DSCH and E-DCH.
It should be noted that the HS-DSCH is the technology in 3GPP R5, the E-DCH is the technology in 3GPP R6, and the HS-DSCH is included in the E-DCH technology, so that, in practical applications, if the UE supports the E-DCH, the UE must also support the HS-DSCH.
The establishment reasons include: a session service calling (aligning generic Call), a Streaming service calling (aligning Streaming Call), an Interactive service calling (aligning Interactive Call), a Background service calling (aligning Background Call), a predetermined service calling (aligning subscribed Call), a session service called (Terminating Call), a Streaming service called (Terminating Call), an Interactive service called (Terminating Call), a Background service called (Terminating Call), an Emergency Call (Originating Call), an intersystem cell reselection (Inter-RAT cell-selection), an intersystem cell change command (Inter-RAT Priority), a Registration (Registration), a Detach (Terminating Call), a High attachment (Originating Call), a low Priority signaling (Terminating Call), a High Priority signaling (signaling Call), a low Priority signaling (Terminating Call), a High attachment (Terminating Call), a low Priority signaling (Terminating Call), a High Priority signaling (Terminating Call) and a High Priority signaling (Terminating Call) The unknown cause is called (Terminating-cause unknown), etc. It should be noted that the establishment cause carried in each rrc establishment request sent by the UE to the RNC includes only one of the above information.
In table 1, the value corresponding to the intersection of the ue capability indication and the establishment cause is the information of the HS-DSCH requirement indication, where NotNeed indicates that HS-DSCH is not supported, May indicates that HS-DSCH is possibly supported, and Must indicates that HS-DSCH Must be supported.
The corresponding relationship between the user terminal capability indication, the establishment cause and the E-DCH requirement indication is shown in table 2,
TABLE 2
In table 2, the value corresponding to the intersection of the ue capability indication and the establishment cause is the information of the E-DCH requirement indication, where Not needed indicates that the E-DCH is Not supported, May indicate that the E-DCH is possibly supported, and Must indicate that the E-DCH is required to be supported.
After receiving a radio resource control establishment request from the UE, the RNC obtains a value corresponding to a cross point of a user terminal capability indication and an establishment reason in the table according to the user terminal capability indication and the establishment reason lookup table 1 and/or table 2 in the radio resource control establishment request. For example: in the radio resource control establishment request from the UE, the user terminal capability indication is to support HS-DSCH, the establishment reason is an aligning Subscribed traffic Call, the look-up table 1 can obtain the HS-DSCH requirement indication as May/Must, the look-up table 2 can obtain the E-DCH requirement indication as Not Need, and the obtained HS-DSCH requirement indication and the obtained E-DCH requirement indication are physical layer requirement information. It should be noted that the values of the HS-DSCH demand indication and the E-DCH demand indication set in the above tables 1 and 2 may be modified according to actual needs.
And the RNC carries the acquired physical layer requirement information in an extension field of a wireless link establishment request and sends the information to the NodeB. The structure of the extension field is shown in table 3, and includes:
TABLE 3
In table 3, the name of the attribute cell/cell group is used to store the physical layer requirement information, the attribute existence flag is used to identify whether the physical layer requirement information exists, the value range in the attribute range is used to store the physical layer requirement information, the type of the attribute cell and the application are used to store the physical layer requirement information generated in step 101, and the value range is Not Need, May, and best.

in step 201, the NodeB receives a radio link setup request from the RNC.
The radio link establishment request received by the NodeB carries physical layer requirement information, including HS-DSCH requirement indication and/or E-DCH requirement indication.
NodeB reads HS-DSCH requirement indication in the physical layer requirement information, if the HS-DSCH requirement indication is Must, a high-capability baseband processing veneer supporting HS-DSCH is selected for UE; if the HS-DSCH requirement indication is May, the base band processing single board with different capability levels can be freely selected, the base band processing single board with high capability level supporting HS-DSCH is preferentially selected, and the base band processing single board with low capability level can be selected under the condition that the base band processing single board with high capability level is insufficient in resources; and if the HS-DSCH requirement indication is Not Need, selecting a baseband processing single board with low power level for the UE.
The NodeB reads an E-DCH requirement indication in the physical layer requirement information, and if the E-DCH requirement indication is a Must, a high-capacity baseband processing single board supporting the E-DCH is selected for the UE; if the E-DCH requirement indication is May, the base band processing single boards with different capability levels can be freely selected, the base band processing single board with high capability level supporting the E-DCH is preferentially selected, and the base band processing single board with low capability level can be selected under the condition that the base band processing single board with high capability level is insufficient in resources; and if the E-DCH requirement indication is Not Need, selecting a low-power-level baseband processing single board for the UE.
