Technical field
The present invention relates to moving communicating field, be particularly related to Radio Link and increase relevant base-station node applying portion (Node-B Application Part, be called for short " NBAP ") and Radio Network Subsystem Application Part (Radio Network Sub-system Application Part is called for short " RNSAP ") technology.
Background technology
UMTS (Universal Mobile Telecommunications System, be called for short " UMTS ") be (the European Standards Institute of ETSI European Telecommunications Standards Institute, abbreviation " ETSI ") solution that on global system for mobile communications (Global System for Mobile communication is called for short " GSM ") network foundation, is smoothly transitted into 3G (Third Generation) Moblie that proposes. It is exactly in fact 3-G (Generation Three mobile communication system).
UMTS can be compatible with existing traditional gsm system. Gsm system will be stage by stage to the UMTS transition. GPRS (the General Packet Radio Service that has now released, be called for short " GPRS ") provide connectionless service to the GSM network, business function and the flexibility of gsm system have been expanded, improved the transfer rate of grouped data, " the 2.5 generation GSM " mobile communication of being known as. And progressively to the 3-G (Generation Three mobile communication system) transition.
The major function of UMTS grounding wireless access network (UMTS Terrestrial Radio Access Network, be called for short " UTRAN ") comprises RRM, such as the wireless mobile management that continues, RAB, safety management, location service management etc. such as handover managements.
Below with reference to Fig. 1, the formation of UTRAN and the interface between the various piece thereof are explained. As shown in Figure 1, in UTRAN, comprise base-station node (Node Base Station is called for short " Node B ") and radio network controller (Radio Network Controller is called for short " RNC ").
Wherein, a Node comprises one or more residential quarters, interface between Node B and the RNC is Iub interface, interface between the RNC is the Iur interface, the interface of RNC and core net is the Iu interface, and the Node B that RNC and its are controlled forms RNS (Radio Network Subsystem is called for short " RNS "), subscriber equipment (User Equipment is called for short " UE ") is that air interface links to each other with UTRAN by Uu interface (not shown in figure 1) then. Be connected a connection with UTRAN for UE, its RNS is called Serving Radio Network System (namely, Serving RNS, be called for short " SRNS "), corresponding RNC is called Serving RNC (namely, Serving RNC, be called for short " SRNC "), when the movement owing to UE exceeded the cell coverage area of getting SRNS, UTRAN allowed SRNS by Iur interface and drift RNS (that is, the Draft RNS that Radio Resource is provided for this UE, be called for short " DRNS ") link to each other to come for this UE access service is provided, corresponding RNC is called drift DRNC (that is, Draft RNC is called for short DRNC).
The chain of command signaling of the Iub of UTRAN and Iur interface is respectively base-station node applying portion (Node-B Application Part, be called for short " NBAP ") and Radio Network Subsystem Application Part (Radio Network Sub-system Application Part, be called for short " RNSAP "), wherein, control radio network controller (Controlling Radio Network Controller, be called for short " CRNC ") by the NBAP signaling its Node B that controls is controlled, SRNC then controls DRNS by the RNSAP signaling. The major function of NBAP and RNSAP is exactly the support that foundation/increase/reprovision/deletion etc. operates to Radio Link.

Under normal conditions, the reference channel of downlink is basic CPICH Common Pilot Channel (Primary Common Pilot Channel, be called for short " P-CPICH "), UE utilizes this reference channel to estimate channel, thereby finish the coherent demodulation to down link signal, for this reason, P-CPICH is that launch in the zone that covers in whole residential quarter.
When adopting beam forming technique, different beams is the part zone of coverage cell only, in order to provide channel estimating corresponding to this wave beam required reference signal for the UE that receives the particular beam signal, need the specific downlink of launching beam, therefore the downlink reference channel that adopts in beam forming technique is the second CPICH Common Pilot Channel (Secondary Common Pilot Channel is called for short " S-CPICH ").
According to the protocol specification TS25.213 of 3GPP, residential quarter can with the downlink scrambler comprise a basic scrambler and 15 the second scramblers. According to the protocol specification TS25.211 of 3GPP, P-CPICH always adopts the basic scrambler of this residential quarter, and S-CPICH then both can adopt the basic scrambler of this residential quarter, also can adopt the second scrambler of this residential quarter.

| Secondary CPICH Information (the 2nd CPICH information) | O (optional) | Common Physical Channel ID 9.2.1.13 public physic channel ID | YES (being) | Ignore (ignoring) |
Specifically, the value of IE " Primary CPICH Usage For Channel Estimation " is enumeration type " Primary CPICH may be used (basic CPICH can use) " and " Primary CPICH shall not be used (basic CPICH cannot use) ", when the value of this IE is " Primary CPICH may be used ", this UE can utilize P-CPICH to carry out channel estimating, when the value of this IE is " Primary CPICH shall not be used ", this UE will not utilize P-CPICH to carry out channel estimating. The value of IE " Secondary CPICH Information " is 0～255 integer, is the ID of each S-CPICH channel in the table 1, and therefore, when this IE occurs, UE can utilize the indicated S-CPICH channel of this IE to carry out channel estimating.
In the prior art, the reference channel that the synchronised radio link reprovision process of NBAP also allows reprovision respective wireless link to adopt, specifically, the IE " RL Information " (wireless link information) of message " RADIO LINK RECONFIGURATION PREPARE (wireless link reconfigured preparation) " has comprised IE " Primary CPICH Usage For Channel Estimation " and IE " Secondary CPICH Information Change (change of the 2nd CPICH information) ", and is as shown in table 4.

| Secondary CPICH Information Change (change of the 2nd CPICH information) | O (optional) | 9.2.2.43A | YES (being) | Ignore (ignoring) |
For RNSAP, because SRNC is not the CRNC of UE and the Radio Resource of not responsible distribution DRNS, the corresponding reference channel of Radio Link of this UE that therefore provides by DRNS is distributed by DRNC and returns SRNC. In the prior art, RNSAP has namely comprised IE " Primary CPICH Usage For Channel Estimation " and IE " Secondary CPICH Information " in the IE " RL Information Response (wireless link information response) " of the success of wireless link process and unsuccessful return messages " RADIO LINK SETUP RESPONSE (wireless link response) " and " RADIO LINK SETUP FAILURE (wireless link failure) ".
Simultaneously, in the return messages of the synchronised radio link reprovision process of RNSAP, also comprised the reference channel that adopts behind the respective wireless link, namely the IE in RNSAP message " RADIO LINK RECONFIGURATION READY (wireless link reconfigured ready) " " RL Information Response (wireless link information response) " has also comprised IE " Primary CPICH Usage For Channel Estimation " and IE " Secondary CPICH Information Change ".
Definition and the usage of IE of the same name among IE among the RNSAP " Primary CPICH Usage For Channel Estimation " and the NBAP are identical, be that its value is enumeration type " Primary CPICH may be used " and " Primary CPICH shall not be used ", when the value of this IE is " Primary CPICH may be used ", this UE can utilize P-CPICH to carry out channel estimating, when the value of this IE is " Primary CPICH shall not be used ", this UE will not utilize P-CPICH to carry out channel estimating. IE among the RNSAP " Secondary CPICH Information " is then different from IE of the same name among the NBAP, it further comprises " DL Scrambling Code (downlink scrambler) " and " FDD DL Channelisation Code Number (FDD downlink channel code number) " two IE, provides respectively scrambler and the channel code configuration information of corresponding S-CPICH.
On the one hand, with the foundation of Radio Link, increase, reconfigure or NBAP/RNSAP process that the operation such as deletion is relevant comprises the processes such as wireless link, Radio Link increase, synchronised radio link reprovision, non-synchronous wireless links reconfiguration. Wherein the wireless link process adopts when this Node B/DRNS not yet sets up the Radio Link of this UE, in case this Node B/DRNS has set up at least one Radio Link of this UE, then can increase by Radio Link increase process the Radio Link of this UE on this Node B/DRNS.
On the other hand, when Node B had a plurality of residential quarter, each residential quarter was separate and not identical to the use of beam forming. Specifically, beam forming may be supported in some residential quarters of same Node B, and beam forming then may not supported in the other residential quarter, and supports equally the residential quarter of beam forming, and the configuration of the corresponding reference channel S-CPICH that adopts also is independently. But, the reference channel that prior art only allows configuration respective wireless link to adopt in the wireless link process, and in Radio Link increase process, then do not support to dispose the reference channel that the respective wireless link adopts. As shown in table 5, the NBAP Radio Link increases in " RADIO LINK ADDITION REQUEST (Radio Link increases request) " message of process, does not comprise the configuration information of the reference channel that Radio Link adopts.
Radio Link for DRNS increases, the different N ode B that DRNC controls and the different districts of same Node B all may be different to the support situation of beam forming and the configuring condition of S-CPICH, but in the prior art, the RNSAP Radio Link increases in the response message " RADIO LINK ADDITION FAILURE (Radio Link increases unsuccessfully) " of response message " RADIO LINK ADDITION RESPONSE (the Radio Link increase responds) " that process successfully operate and unsuccessful operation, does not comprise equally the configuration information of the reference channel that Radio Link adopts.
For NBAP, the problems referred to above can cause a problem, that is, the newly-increased Radio Link in other residential quarter of same Node B of this UE can't dispose corresponding reference channel. According to prior art, when clearly not disposing the reference channel of a wireless links, will adopt P-CPICH as the reference channel defaultly. Therefore, this will be so that the newly-increased Radio Link in other residential quarter of same Node B of this UE can't adopt beam forming technique. Even can utilize the reference channel of these newly-increased Radio Links of synchronised radio link reprovision process reprovision, but this obviously will increase the complexity of signaling control and the signaling amount of transmission, increase the processing complexity of system. And for RNSAP, because therefore the information of the reference channel of the Radio Link that SRNC can not obtain to increase newly can't correctly send to the reference channel information of respective wireless link UE, thereby will cause UE can't correctly receive the signal of respective wireless link.

CRNC determines used reference channel according to the ability that the residential quarter at newly-increased Radio Link place is supported beam forming technique. If beam forming technique is supported in the residential quarter at newly-increased Radio Link place, then with the S-CPICH of this residential quarter as the reference channel; If beam forming technique is not supported in the residential quarter at newly-increased Radio Link place, then with the P-CPICH of this residential quarter as the reference channel.
Because support according to the residential quarter beam forming technique capabilities setting the reference channel of Radio Link, so can give full play to the performance of the Node B that supports the beam forming function, Effective Raise power system capacity. And in the prior art because be not newly-increased radio link configuration reference channel, can only use P-CPICH as the reference channel defaultly, so even the residential quarter support also to use beam forming technique.
Because in the increase process, just disposed reference channel, no longer need the reference channel by extra these newly-increased Radio Links of synchronised radio link reprovision process reprovision, so can reduce the complexity of signaling control and the signaling amount of transmission, reduce the processing complexity of system.
After this enter step 420, Node B is according to the reference channel information of receiving, for UE increases Radio Link.
After this enter step 430, Node B returns response message to " RADIO LINK ADDITION REQUEST " message to CRNC (being the SRNC among Fig. 4). If increase the operation success of Radio Link in the step 420, then return " RADIO LINK ADDITION RESPONSE " message; If increase the operation failure of Radio Link in the step 420 then return " RADIO LINK ADDITION FAILURE " message.
After this, CRNC notice UE increases Radio Link with identical reference channel.
In the second embodiment, UE has moved among the SNRC control range Node B in addition, and DRNC is as CRNC, and the increase flow process of Radio Link as shown in Figure 5.
In step 510, SRNC sends " RADIO LINK ADDITION REQUEST " message in the RNSAP agreement to DRNC, and request DRNS is that UE increases Radio Link.
After this enter step 520, DRNC is as CRNC, sends " RADIO LINK ADDITION REQUEST " message in the NBAP agreement to Node B, and indication Node B is that UE increases Radio Link, wherein the reference channel information of newly-increased Radio Link. Step 520 is similar to the step 410 in the first embodiment, has not done repeat specification here.
After this enter step 520, Node B is according to the reference channel information of receiving, for UE increases Radio Link.
After this enter step 530, Node B returns response message to " RADIO LINK ADDITION REQUEST " message to DRNC. If increase the operation success of Radio Link in the step 520, then return " RADIO LINK ADDITION RESPONSE " message; If increase the operation failure of Radio Link in the step 520 then return " RADIO LINK ADDITION FAILURE " message.
After this enter step 550, when DRNC receives from the response message of Node B, return response message to " the RADIO LINK ADDITION REQUEST " message in the RNSAP agreement to SRNC. Carry the reference channel information of newly-increased Radio Link in this response message, to issue reference channel information entrained in " RADIO LINK ADDITION REQUEST " message of Node B consistent with DRNC in the step 520. The type of response message depends on that Node B increases the result of operation to Radio Link in the step 520, if increase the operation success of Radio Link in the step 520, then returns " RADIO LINK ADDITION RESPONSE " message; If increase the operation failure of Radio Link in the step 520 then return " RADIO LINK ADDITION FAILURE " message.
In the present embodiment, increase in the response message " RADIO LINK ADDITION RESPONSE " and " RADIO LINK ADDITION FAILURE " of process at the RNSAP Radio Link, return the configuration information of the reference channel that the respective wireless link adopts. Shown in table 7 and table 8, in the IE " RL Information Response " (wireless link information response) of " RADIO LINK ADDITION RESPONSE " message, and in the IE of " RADIO LINK ADDITION FAILURE " message " Successful RL Information Response " (successful wireless link information response), increase optional IE " Primary CPICH Usage For Channel Estimation " (basic CPICH channel estimating usage) and optional IE " Secondary CPICH Information " (the 2nd CPICH information), wherein, these two IE definition and usage are identical with existing definition and usage in the RNSAP agreement.
Specifically, IE " Primary CPICH Usage For Channel Estimation " value is enumeration type " Primary CPICH may be used " (basic CPICH can use) and " Primary CPICH shall not be used " (basic CPICH cannot use), when the value of this IE is " Primary CPICH may be used ", this UE can utilize P-CPICH to carry out channel estimating, when the value of this IE is " Primary CPICH shall not be used ", this UE will not utilize P-CPICH to carry out channel estimating. IE " Secondary CPICH Information " further comprises two IE of " DL Scrambling Code " (downlink scrambler) and " FDD DL Channelisation Code Number " (FDD downlink channel code number), provides respectively scrambler and the channel code configuration information of corresponding S-CPICH. As IE " Primary CPICH may be used " and IE " Secondary CPICH Information " when all not occurring, then defaultly with P-CPICH as the reference channel.
After this, SRNC notice UE increases Radio Link with identical reference channel.
The present invention by the Radio Link that allows RNSAP increase the success of process and unsuccessful response message in return the reference channel that the respective wireless link adopts, thereby so that the reference channel information that SRNC can adopt the respective wireless link offers UE, thereby support this UE newly-increased Radio Link in this DRNS to adopt beam forming technique.
