From the description of the foregoing description one as can be known, in different net system switching process, if the Target cell that UE and switching are gone into is all supported the DC-HSDPA function, then Target RNC starts the DC-HSDPA function by notice UE, UE is being switched from different system behind the sub-district of supporting DC-HSDPA, can set up the HSDPA transmission bearer of DC-HSDPA mode, thereby improve the descending peak rate of UE.
Embodiment two, a kind of inter-system switchover processing method, the flow process of this method as shown in Figure 2.
Among Fig. 2, S200, Target RNC (Radio Network Controller, radio network controller) receive handoff request information.
Handoff request information among the S200 is that expression UE will switch into the handoff request information to the 3G system from non-3G system.
Handoff request information among the S200 can be at first sends to CN (Core Network, core net) by the Access Network (promptly switching the initiator) of non-3G system, by core net the handoff request information that it receives is forwarded to Target RNC again.The switching initiator here is meant the network equipment in the non-3G system, as evolution base station (eNodeB) among BSC in the 2G system (base station control station) or the LTE (Long Term Evolution) or the like.
Handoff request information among the S200 can be carried at migration and require in the message to send to core net by switching the initiator, and will move the handoff request information that requires in the message by core net and be carried at and send to Target RNC in the migration request message.Certainly, the handoff request information among the S200 also can be carried in other message and switch between initiator and the core net and transmitting between core net and the Target RNC.
Also carry the information and the Target RNC information of Target cell in the message that carries handoff request information (requiring message) that the switching initiator sends as migration, in addition, can also carry the information of UE in the message that carries handoff request information that the switching initiator sends.The information of Target cell can comprise: Target Cell Identifier.Target RNC information can comprise the Target RNC sign.The information of UE can comprise: the ability information of UE.The ability information of UE can comprise that UE supports the information of DC-HSDPA, and promptly the information of UE (or ability information of UE) can embody UE and whether support DC-HSDPA.Do not support that at UE under the situation of DC-HSDPA, the information of UE can not comprise: UE does not support the information of DC-HSDPA.The information of the UE here also can be called the relevant information of UE.UE can report it whether to support the information of DC-HSDPA function to switching the initiator, and like this, switching the initiator can be according to the information of the UE that carries in the above-mentioned message of the information setting that UE reports.
Target RNC can know according to Target Cell Identifier whether this Target cell supports the DC-HSDPA function.Core net can be determined Target RNC according to the information of the Target RNC ID that carries in the message after receiving the message that carries handoff request information of switching initiator's transmission, and sends the message that carries handoff request information to Target RNC.
S210, Target RNC judge whether this UE and Target cell all support DC-HSDPA after receiving the handoff request information that core net sends.If Target RNC is judged above-mentioned UE and Target cell is all supported DC-HSDPA, then arrive S220, otherwise, to S230.
In S210, Target RNC can judge whether this UE and Target cell all support DC-HSDPA according to the information of obtaining from the message that receives.
Target RNC judges whether Target cell supports the concrete example of DC-HSDPA to be: Target RNC obtains Target Cell Identifier from the message that receives, and utilize this Target Cell Identifier from its canned data and/or other network equipment canned datas, to search the information whether this Target cell supports DC-HSDPA, according to the information that finds determine this switch into Target cell whether support DC-HSDPA.
Target RNC judges whether UE supports the concrete example of DC-HSDPA to be: Target RNC judges that whether carrying UE in its message that carries handoff request information that receives supports DCHSDPA ability cell, this UE supports that DCHSDPA ability cell is optional cell, support at UE under the situation of DC-HSDPA, carry in the message of handoff request information and can carry this cell.Target RNC carries this cell in judging its message that receives after, determine UE and support DC-HSDPA, otherwise, judge UE and do not support DC-HSDPA.
S220, Target RNC send handover configurations information to UE, and for example, Target RNC is by core net and switch the initiator to UE transmission handover configurations information, includes the announcement information that notice UE starts the DC-HSDPA function in this handover configurations information.Optionally, behind S220, can arrive S240.
The announcement information that above-mentioned notice UE starts the DC-HSDPA function can adopt the form of Downlink secondarycell info (descending auxilliary carrier cell information) cell to represent, and this cell can be carried at and switch in the UTRAN order.Be that handover configurations information is to send to UE with the form that switches to UTRAN order, and switching in the UTRAN order of S120 carry Downlink secondary cell info cell, the effect of this cell is to notify UE to start the DC-HSDPA function.
If the handoff request information that Target RNC receives in S200 is carried in the migration request message, then Target RNC to the concrete example that UE sends handover configurations information is among the S220: the UTRAN command group that switches to that Target RNC will carry Downlink secondary cell info cell installs in the migration request acknowledge message, and the information in the Downlink secondary cell info cell of this moment is used for expression notice UE and starts the DC-HSDPA function; Target RNC sends this migration request acknowledge message to core net, core net is after receiving the migration request acknowledge message, obtain from the migration request acknowledge message and switch to the UTRAN order, core net will switch to the UTRAN command group and install in the migration order, and send the migration order to switching the initiator; Switch after the initiator receives the migration order, from the migration order, obtain and switch to the UTRAN order, switch the initiator and send this to UE and switch to the UTRAN order.At this moment, switching in the UTRAN order that UE receives carries Downlink secondary cell info cell, and UE can start the DC-HSDPA function according to the information of carrying in this cell.
S230, Target RNC send handover configurations information to UE, send handover configurations information by core net and switching initiator to UE as Target RNC, do not comprise in this handover configurations information that notice UE starts the announcement information of DC-HSDPA function.Optionally, behind S230, can arrive S240.
In S230, Target RNC can send handover configurations information to UE according to existing processing mode.If the handoff request information that Target RNC receives in S200 is carried in the migration request message, then Target RNC to the concrete example that UE sends handover configurations information is among the S230: Target RNC will switch to the UTRAN command group and install in the migration request acknowledge message, and Downlink secondary cell info cell is not carried in switching in the UTRAN order here; Target RNC sends the migration request acknowledge message to core net, core net is after receiving this migration request acknowledge message, obtain from the migration request acknowledge message and switch to the UTRAN order, core net will switch to the UTRAN command group and install in the migration order, and send the migration order to switching the initiator; Switch after the initiator receives the migration order, from the migration order, obtain and switch to the UTRAN order, switch the initiator and send this to UE and switch to the UTRAN order.At this moment, Downlink secondary cell info cell is not carried in switching in the UTRAN order that UE receives, thereby UE can not start the DC-HSDPA function according to the UTRAN order that switches to that receives.
In addition, Target RNC among the S230 also can not adopt existing processing mode to send handover configurations information to UE, for example, the UTRAN command group that switches to that Target RNC will carry Downlink secondary cell info cell installs in the migration request acknowledge message, information in the Downlink secondary cell info cell among the S230 can't be expressed notice UE and start the DC-HSDPA function, promptly the effect of existing Downlinksecondary cell info cell is revised; Target RNC sends the migration request acknowledge message to core net, core net is after receiving the migration request acknowledge message, obtain from the migration request acknowledge message and switch to the UTRAN order, core net will switch to the UTRAN command group and install in the migration order, and send the migration order to switching the initiator; Switch after the initiator receives the migration order, from the migration order, obtain and switch to the UTRAN order, switch the initiator and send this to UE and switch to the UTRAN order.At this moment, though switching in the UTRAN order that UE receives carries Downlink secondary cell info cell, but, because this cell does not represent to notify UE to start the DC-HSDPA function, therefore, UE can not start the DC-HSDPA function operations according to the information and executing of carrying in this cell.
S240, Target RNC receive the message that handover configurations is finished information that carries that UE sends.Optionally, can arrive S250 behind the S240.
Whether S250, Target RNC are finished information according to the handover configurations that receives and are sent announcement information to core net, switch with the different system of notice core net to complete successfully.
From the description of the foregoing description one as can be known, Target RNC is by after determining UE and switch the Target cell of going into all to support the DC-HSDPA function in different net system switching process, notice UE starts the DC-HSDPA function, UE is being switched from different system behind the sub-district of supporting DC-HSDPA, can set up the HSDPA transmission bearer of DC-HSDPA mode, thereby improve the descending peak rate of UE.
Embodiment three, a kind of inter-system switchover processing method, as shown in Figure 3.
Among Fig. 3, the base station control station of S300,2G system sends RELOCATIONREQUIRED (migration requires) message to core net.This migration requires to carry in the message relevant information of target cell information, Target RNC sign and portable terminal etc.Target cell information comprises Target Cell Identifier.The relevant information of portable terminal comprises mobile terminal capability information etc.Mobile terminal capability information comprises the information of portable terminal support DC-HSDPA etc.
After S310, core net receive RELOCATION REQUIRED message, from the information that this message is carried, obtain the Target RNC sign, and send RELOCATION REQUEST (migration request) message to the corresponding wireless network controller according to the Target RNC sign.
S320, described target radio network controller receive RELOCATION REQUEST message, and judge according to the relevant information and the target cell information of the portable terminal that carries in this message, if portable terminal and Target cell are all supported the DC-HSDPA function, then radio network controller adds Downlink secondary cell info cell in HANDOVER TOUTRAN COMMAND (switching to the UTRAN order), starts the DC-HSDPA function with the notice portable terminal.Radio network controller is assembled into HANDOVERTO UTRAN COMMAND in RELOCATION REQUEST ACKNOWLEDGE (migration request affirmation) message, and sends RELOCATION REQUESTACKNOWLEDGE message to CN.
After S330, core net receive RELOCATION REQUEST ACKNOWLEDGE message, the HANDOVER TO UTRANCOMMAND that carries Downlink secondary cell info cell is extracted from RELOCATION REQUEST ACKNOWLEDGE message, core net is assembled into HANDOVER TO UTRAN COMMAND in RELOCATIONCOMMAND (migration order) message, then, core net sends to this base station control station with RELOCATION COMMAND message.
After S340, this base station control station are received RELOCATION COMMAND message, from this message, obtain the HANDOVER TO UTRANCOMMAND that carries Downlink secondary cell info cell, and send the HANDOVER TO UTRAN COMMAND that carries Downlink secondary cell info cell to portable terminal.HANDOVER TO UTRAN COMMAND also can be called different system and switch into order.
S350, portable terminal carry out corresponding handover configurations according to the information of carrying among the HANDOVER TO UTRANCOMMAND after receiving the HANDOVER TO UTRAN COMMAND that carries Downlink secondary cell info cell; The configuration here comprises: when portable terminal switches to the 3G system from non-3G system such as 2G or LTE system, start the DC-HSDPA function.Portable terminal informs that by sending HANDOVER TO UTRAN COMPLETE (switching to UTRAN finishes) message the radio network controller handover configurations finishes.Wherein handover configurations is finished information and can be included portable terminal when non-3G system such as 2G or LTE system switches to the 3G system, has successfully started the information of DC-HSDPA function.Above-mentioned HANDOVER TO UTRAN COMPLETE also can be called different system and switch into finishing message.
After S360, radio network controller receive the HANDOVER TO UTRANCOMPLETE message that portable terminal sends, send RELOCATION COMPLETE (migration is finished) message to core net, with the notice core net: portable terminal is finished different system and is switched.
