Description

Cell capability notifying method and radio network control entity

Technical field

The present invention relates to the wireless network control technical field, particularly a kind of cell capability notifying method and a kind of radio network control entity.

Background technology

Along with the continuous evolution and the development of UMTS (UMTS) system, constantly introduce some new characteristics, make the ability of network be enhanced.Wherein strengthen forward access channel (FACH overHSDPA, E-FACH), strengthen PCH (PCH over HSDPA, E-PCH) by the standard discussion, possibly also can introduce in the future the enhanced random access channel (RACH over HSUPA, E-RACH).

In the prior art,, in the sub-district of supporting E-FACH, can receive the former data that should receive at the FACH channel at high speed descending sharing channel (HS-DSCH) channel for the UE that supports above-mentioned E-FACH.In the moving process of UE, will relate to the problem of RRC chain rupture like this, specifically as shown in Figure 1.

In Fig. 1; After not supporting under source radio network controller SRNC as the UE that supports E-FACH to receive data among the sub-district cell1 of E-FACH, move to after another floating radio network controller DRNC supports the sub-district cell2 of E-FACH down, in step 1; UE is after DRNC initiates cell update (CELLUPDATE) message; Owing on the BCCH of cell2 sub-district, can broadcast the information that it supports E-FACH, after UE knows that cell2 also supports E-FACH, will monitor the HS-DSCH channel and receive data.After this, in step 2, DRNC sends up signaling transmission indication (ULSIGNALLING TRANSFER INDICATION) message to SRNC, initiates the cell update request to SRNC; In step 3 to 5; SRNC is according to the UL SIGNALLING TRANSFERINDICATION message that receives; With the mutual public transmission channel resource request of DRNC (COMMON TRANSPORT CHANNEL RESOURCE REQUEST) message and public transmission channel resource response (COMMON TRANSPORT CHANNEL RESOURCE RESPONSE) message, thereby set up common FACH transfer of data; Afterwards in step 6; DRNC also can send common FACH transfer of data to cell2; These data are transmitted through auxiliary publish control physical channel (S-CCPCH) by the NodeB at cell2 place; And, just can't receive the data on the S-CCPCH channel because UE is monitoring HS-DSCH channel wait FACH data, cause the RRC chain rupture.

In technology shown in Figure 2, to the shortcoming of Fig. 1, in step 2, DRNC receives the cell update message from UE, determines UE and supports E-FACH; After this; Send UL SIGNALLING TRANSFER INDICATION message in step 3 to SRNC; And after step 4 receives the COMMON TRANPORT CHANNEL RESOURCE REQUEST message that SRNC returns; Determine SRNC in step 5 and do not support E-FACH; Then send the message that discharges the Radio Link control connection (RRC CONNECTION RELEASE usingE-FACH) that adopts E-FACH in step 6 to UE, the Radio Link control (RRC) that notice UE discharges E-FACH connects, thereby UE can receive the FACH data at the S-CCPCH channel.

In technology shown in Figure 2, though prevented the RRC chain rupture,, initiate COMMON TRANSPORTCHANNEL RESOURCE REQUEST up to SRNC because DRNC does not know in advance whether SRNC supports E-FACH, DRNC knows that just SRNC does not support E-FACH.So just cause the delay of RRC release time of UE, increased the break period of UE; Increased the signaling of Iur simultaneously, made the Iur complex disposal process; Also increased the processing load of DRNC.

And for E-PCH, move to DRNC from SRNC for UE, and under DRNC the resident scene in sub-district; Paging (paging) process will be crossed over the Iur interface between SRNC and the DRNC, and SRNC and DRNC are different based on the E-PCH ability, and the paging processing mode also should be different; For example; As SRNC support E-PCH, when DRNC also supported E-PCH, the paging information of Iur interface should pass in high speed descending sharing channel frame structure bag (HS-DSCH FP) data; As SRNC support E-PCH, when DRNC did not support E-PCH, the paging information of Iur interface should transmit in paging request (Pagingrequest) signaling.

But because in the prior art, do not have the means of E-PCH capabilities exchange between SRNC and the DRNC, SRNC can not know whether DRNC supports E-PCH, then can not make judgement, thereby also can't select suitable transmission means.

Along with the continuous evolution and the development of UMTS system, also in evolution, the characteristic of HSPA+ is introduced at present from the framework in the UMTS system, and its core concept is to become a new node to RNC and NodeB merging, and we simply are referred to as NodeB+ (perhaps NB+).By up till now, there are two kinds of deployment scenario in known HSPA+ system.Specifically as shown in Figure 3.What the left hand view 3a of this figure described is that HSPA+ independence carrier frequency is disposed (stand-alone) scene, that is, this system only supports PS professional, and the CS business is still carried by traditional NodeB and RNC.What the right part of flg 3b of Fig. 3 described is that the HSPA+ carrier frequency is shared deployment scenario, and at this moment, the HSPA+ system supports that simultaneously PS is professional and CS is professional, and promptly PS and CS business can insert core net through NodeB+.

Dispose under (stand-alone) scene at above-mentioned HSPA+ independence carrier frequency, the HSPA+ system only supports PS professional, and the CS business is still carried by traditional NodeB and RNC.Under this deployment scenario; Use the professional user of CS to move from the zone of zone under NodeB+ covers under traditional RNC covering; Or PS+CS user is when NodeB+ initiates the CS business; The SRNC function that needs to handle the professional NodeB+ of PS is reoriented to traditional RNC, otherwise possibly come the better CS business experience to the user.In addition, the HSPA+ system supports CS professional under the scene though the carrier frequency of HSPA+ is shared, and obtains better business experience in order to make the user, also can correspondence carry out above-mentioned repositioning process.But in the prior art,, make above-mentioned repositioning process have following defective because RNC can not be known the HSPA+ ability of adjacent R NC:

At first, for first kind, at UE when legacy network moves to the HSPA+ network that covers, for example in Fig. 4; 10 move on to sub-district 9 from the sub-district, or 3 move to sub-district 4 from the sub-district, in this process, if UE is using CS professional; And RNC2 or RNC1 do not know that NodeB2 or NodeB1 are HSPA+NB+, just think that it is traditional NodeB, so initiate the relocation process to it; Be reoriented to the HSPA+ network to UE, the professional perception of the CS that brings UE is bad, and because HSPA+NB+ itself does not support CS professional; Can be reoriented to RNC2 or RNC1 to UE again, cause repeating switching, further reduce user's business experience.

Secondly; For second kind, UE initiates CS at the HSPA+ network and calls out, and for example the CS calling is initiated in position in Fig. 49 or position 4; Then because HSPA+NodeB2 or HSPA+NodeB2 do not know that which sub-district, this zone is a conventional cell; Can't find conventional cell to initiate to initiate reorientation to this sub-district, because can't reorientation, greatly reduce user's business experience.

In sum; NodeB+, radio network controller and HSPA+NodeB etc. carry out the entity of wireless network control at network side; Owing to can't obtain the ability information of sub-district under other radio network control entities, thereby caused to select between RRC chain rupture, the radio network control entity suitable delivering path and CS business problems such as can't reorientate.
