Background technology
At E-HSPA (Evolved High Speed Packet Access, the high-speed packet access of evolution) evolution in the works, the network architecture is to flattening evolution, be RNC (Radio Network Controller, radio network controller) function moves down among the NodeB (base station), make NodeB become NodeB+ (base station of enhancing), i.e. eHSPA NodeB.
The design of the E-HSPA flattening network architecture mainly is in order to optimize PS (Packet Switched, packet switching) business, but this network architecture still needs to support CS (Circuit Switched, circuit switching) business.In order to support the CS business, the scheme that adopts is at present: with SRNS (the Serving RadioNetwork Subsystem of CS business, SRNS Serving Radio Network Subsystem) function is all moved on the Target RNC, eHSPANodeB only is responsible for the SRNS function of PS business, thereby avoided the phenomenon that PS is professional and the CS service resources conflicts under the common carrier frequency scene, and reduced the complexity of eHSPA NodeB.
For Carrier Sharing (common carrier frequency) application scenarios, present CS business realizing process comprises:
When UE (User Equipment, subscriber equipment) initiated the CS business, eHSPA NodeB triggered the SRNS Relocation (SRNS reorientation) of CS business.EHSPA NodeB sends Relocation Required (re-positioning request) message to core net.The information that carries Relocation Type (reorientation type) field in the Relocation Required message and need pass to Target RNC.UE according to SRNS Relocation relates to the difference that mode, UE do not relate to mode, and the Relocation the type field of eHSPA NodeB in can Relocation Required message is set to UE involved inrelocation of SRNS (UE of SRNS relates to mode) or UE not involved in relocationof SRNS (UE of SRNS does not relate to mode).The information that needs in the Relocation Required message pass to Target RNC can comprise: d-RNTI that is used to identify UE that the radio link parameter that eHSPA NodeB has set up (RRCContainer), Target Cell ID (Target Cell Identifier information), eHSPA NodeB have distributed (d-Radio Network Temporary Identity, the drift radio net is discerned temporarily) or the like.
Core net sends RelocationRequest (re-positioning request) message according to the Relocation Required message that receives to Target RNC.
After Target RNC receives the Relocation Request message that core net sends, initiate RL (Radio Link) and set up process.Target RNC is initiated RL and is set up the no longer detailed description in present specification of process flow process afterwards.
In realizing process of the present invention, the inventor finds to exist at least in the prior art following two problems:
1, be under the situation of UE involved in relocation of SRNS in the Relocation the type field, the RL that Target RNC is initiated sets up process and is equivalent to direct-cut operation, be that RL that Target RNC is initiated sets up that process can trigger that the physical channel of eating dishes without rice or wine is reshuffled and processing such as synchronous, thereby can cause problems such as propagation delay time is big, cutting off rate height.And owing to stipulate in the present standard: newly-built RL can not be the link that is present in the current Active Set in the physical channel reconfiguration course.Therefore, the RL parameter of Target RNC in the Relocation Required message that RL parameter that eHSPA NodeB sends must be sent with eHSPA NodeB is inequality.Otherwise, can cause setting up the RL procedure failure.
2, be that Target RNC need keep the original air-link resources of UE under the situation of UE not involved in relocation of SRNS in the Relocation the type field.But, if Target RNC is not supported the RL parameter in the Relocation Required message, for example, Target RNC is not supported spreading factor SF2 etc., then can make Target RNC can't keep the original air-link resources of UE, thereby cause follow-up flow process successfully to realize.

Specific embodiment
At first the implementation method of the SRNS reorientation of the embodiment of the invention is described below.
At first, Target RNC receives RELOCATION REQUEST message.The RELOCATION REQUEST message that Target RNC receives is that the source end from the SRNS reorientation sends, strengthen the source end that the base station can be used as the SRNS reorientation, for example strengthen the base station and send RELOCATION REQUEST message to core net, core net sends RELOCATION REQUEST message to Target RNC after receiving and strengthening the next RELOCATION REQUEST message of base station transmits.Core net can be directly be forwarded to Target RNC with strengthening the RELOCATION REQUEST message that base station transmits comes, and also can transfer to Target RNC to after strengthening RELOCATION REQUEST message that base station transmits comes and carrying out protocol conversion etc. and handle.
Target RNC judges in its RELOCATION REQUEST message that receives whether carry the indication information that can select relocation loading mode.This indication information can be to strengthen the base station to be provided with.The effect of this indication information is: show that Target RNC can oneself select relocation loading mode.The relocation loading mode here can relate to mode for the subscriber equipment of SRNS, also can not relate to mode for the subscriber equipment of SRNS.Certainly, relocation loading mode also can be alternate manner.
Target RNC does not carry the indication information that can select relocation loading mode in judging RELOCATION REQUEST message after, Target RNC can be handled this RELOCATION REQUEST message according to its existing processing mode.For example, Target RNC does not carry the indication information that can select relocation loading mode and the Relocation the type field in the RELOCATION REQUEST message when being UE involved in relocation ofSRNS in judging RELOCATION REQUEST message, then Target RNC can adopt the UE of SRNS to relate to mode to initiate RL and set up process.Again for example, Target RNC does not carry the indication information that can select relocation loading mode and the Relocation the type field in the RELOCATION REQUEST message when being UE not involved in relocation ofSRNS in judging RELOCATION REQUEST message, then Target RNC can adopt the UE of SRNS not relate to mode to initiate RL and set up process.
Target RNC carries the indication information that can select relocation loading mode in judging RELOCATION REQUEST message after, can continue to judge whether it supports the radio link parameter in the RELOCATION REQUEST message.Certainly, Target RNC judges that its step of whether supporting the radio link parameter in the RELOCATION REQUEST message also can be before Target RNC judges whether carry the indication information that can select relocation loading mode in the RELOCATION REQUEST message, and the embodiment of the invention does not limit the specific implementation process of above-mentioned two deterministic processes.Support radio link parameter in this RELOCATION REQUEST message if Target RNC determines to carry in the RELOCATION REQUEST message indication information that can select relocation loading mode and its, then Target RNC is selected the subscriber equipment of SRNS not relate to mode to continue follow-up flow process.For example, Target RNC utilizes the subscriber equipment of SRNS not relate to mode to initiate RL and set up process.Do not support radio link parameter in this RELOCATION REQUEST message if Target RNC determines to carry in the RELOCATION REQUEST message indication information that can select relocation loading mode and its, then Target RNC is selected the subscriber equipment of SRNS to relate to mode to continue follow-up flow process.For example, Target RNC utilizes the subscriber equipment of SRNS to relate to mode to initiate RL and set up process.
In the description of the foregoing description, can select the indication information of relocation loading mode can be carried in Relocation Type (reorientation type) field of RELOCATION REQUEST message, be that the embodiment of the invention can be expanded the Relocation the type field, make the Relocation the type field can carry the indication information that to select relocation loading mode.
At present, the value of Relocation the type field has two kinds, a kind of is UE not involved inrelocation of SRNS (subscriber equipment of SRNS does not relate to mode), and another kind of is UE involved inrelocation of SRNS (subscriber equipment of SRNS relates to mode).When the indication information that can select relocation loading mode was carried in the Relocation the type field, the value of Relocation the type field can comprise three kinds.Setting can select the indication information of relocation loading mode to represent that by CS service enabling relocation ofSRNS (the professional SRNS reorientation that triggers of CS) (perhaps Combining ofUE not involved andUE involved in relocation of SRNS (UE relates to UE and do not relate to the SRNS reorientation that mode is mixed)) then three of the Relocation the type field kinds of different values can be as shown in table 1:
Table 1
| IE/Group?Name | Presence | Range | IEtype?andreference | Semantics?description |
| Relocation?Type | M | ENUMERATED(UE?not?involvedin?relocation?ofSRNS，UEinvolved?inrelocation?ofSRNS，CS?serviceenablingrelocation?ofSRNS，...) |
In the table 1, IE type and reference is the Relocation the type field, as can be seen from Table 1, the Relocation the type field can be set to UE not involved in relocation of SRNS or be set to UE involved in relocation of SRNS or be set to CS service enablingrelocation of SRNS.
When the indication information that can select relocation loading mode was carried in the Relocation the type field, the value of Relocation the type field also can be not only a situation about describing in the above-mentioned table 1.For example, the value of Relocation the type field can only comprise CS service enabling relocation of SRNS; Again for example, the value of Relocation the type field can three kinds of values in comprising above-mentioned table 1 outside, also comprise other content; Also have, the value of Relocation the type field can be in other value that also comprises on the basis that comprises CS serviceenabling relocation of SRNS except that UE not involved in relocation ofSRNS, UE involved in relocation of SRNS.
When the indication information that can select relocation loading mode was carried in the Relocation the type field, the value of the Relocation the type field that Target RNC can be by judging RELOCATION REQUEST message determined whether carry the indication information that can select relocation loading mode in the RELOCATION REQUEST message.
Can select the indication information of relocation loading mode also can be carried in other field of RELOCATION REQUEST message, for example, in RELOCATION REQUEST message, increase new field, carry the indication information that to select relocation loading mode by this field that increases newly.Embodiment of the present invention does not limit the concrete manifestation form of indication information in RELOCATION REQUEST message that can select relocation loading mode.
Target RNC needs also in the above-mentioned RELOCATION REQUEST message to carry that radio link parameter (RRC Container), Target Cell ID, eHSPA NodeB that eHSPA NodeB set up distributed is used to d-RNTI that identifies UE or the like, so that can carry out the processing of follow-up flow process easily.Also need to comprise some physical layer parameters among the above-mentioned RRCContainer, for example: can comprise among the RRC Container: Maximum allowed UL TX power (the maximum uplink transmission power that allows), Uplink DPCH info (uplink special physical channel information), E-DCH Info (strengthening dedicated channel information), DownlinkHS-PDSCH Information (down high speed Physical Downlink Shared Channel), Downlink informationcommon for all radio links (all descending public informations of Radio Link), Downlink informationfor each radio link (every wireless links downlink information) or the like.
Below in conjunction with accompanying drawing the SRNS reorientation implementation method that the embodiment of the invention provides is described.
Among Fig. 1, step 1, Target RNC receive RELOCATION REQUEST message, to step 2.
Among Fig. 2, step 1, not only initiate the CS business but also initiate under the situation of PS business at UE, strengthening the base station is that eHSPA NodeB is respectively to the SGSN of core net (Serving GPRS Support Node, Serving GPRS Support Node), MSC sends Relocation Required (re-positioning request) message, to step 2.
In the step 1, the information that carries the Relocation the type field and need pass to Target RNC in the Relocation Required message that eHSPA NodeB sends.The information that need pass to Target RNC can comprise: the radio link parameter that eHSPA NodeB has set up (RRC Container), Target Cell ID, eHSPA NodeB have distributed is used to d-RNTI that identifies UE or the like.
In addition, in the step 1 UE not only initiated the CS business but also initiate the PS business situation can for: this UE has initiated the CS business again under the situation that has the PS business; Also can initiate the professional and CS business of PS simultaneously for: this UE.
In above-mentioned steps 3, Target RNC can learn that it still is at the repositioning process of a plurality of core net that eHSPA NodeB has initiated at a core net according to the cell that carries in the Relocation Request message, for example, Target RNC can learn that it still is at the repositioning process of a plurality of core net that eHSPA NodeB has initiated at a core net according to the Number of Iu Instances that comprises in the Source RNCTo Target RNC Transparent Container cell that carries in the Relocation Request message.Therefore, Target RNC can learn whether it receives the Relocation Request message that all core net are sent.
In step 4, Target RNC can only be initiated the process of setting up of a Radio Link at its two Relocation Request message that receive.
Embodiment of the present invention also provides the implementation method of another kind of SRNS reorientation, and the implementation method of this implementation method and foregoing description is basic identical, and its difference comprises: can select the indication information of relocation loading mode to transmit by other message.That is to say, in the present embodiment, can select the indication information of relocation loading mode can be carried in the RELOCATION REQUEST message, can be carried in other message yet, present embodiment does not limit the form of expression of the concrete message of carrying the indication information that can select relocation loading mode.This indication information be carried in other message situation for example, can increase a piece of news newly at the indication information that can select relocation loading mode, carry this indication information by this newly-increased message.When the indication information that can select relocation loading mode is carried in the RELOCATION REQUEST message, can adopts in the reorientation type field of describing in the above-mentioned execution mode that this indication information is carried at RELOCATION REQUEST message or be carried at the medium method of other field of RELOCATION REQUEST message.No longer the specific implementation process of this execution mode is carried out repeat specification at this.
By send the indication information that to select relocation loading mode to Target RNC, for example send the RELOCATION REQUEST message carry the indication information that to select relocation loading mode, make Target RNC whether support the concrete condition of radio link parameter to choose UE and do not relate to mode or UE and relate to mode and continue follow-up flow process according to it to Target RNC; Like this, support at Target RNC under the situation of radio link parameter, avoided adopting UE to relate to mode and trigger that the physical channel of eating dishes without rice or wine is reshuffled and the phenomenon of handling such as synchronous; Do not support at Target RNC under the situation of radio link parameter, avoided adopting UE not relate to mode and phenomenon that the follow-up flow process brought can't successfully realize; Thereby reduced propagation delay time, reduced cutting off rate, guaranteed that the SRNS repositioning process can successfully realize.
The system of the realization SRNS reorientation that the embodiment of the invention provides comprises: Target RNC, enhancing base station and core net.Wherein, be provided with first module and sending module in the enhancing base station; Be provided with first judge module, second judge module and processing module in the Target RNC.The core net here can for one, also can be a plurality of dissimilar core net.
