Second resource allocation unit 903 is used for setting up reason according to the RRC connection that the migration request message that described the 3rd receiving element 901 receives is carried and carries out resource allocation.For example, second resource allocation unit 903 can connect the priority of setting up reason according to the RRC that carries and carry out resource allocation, specifically, for example, set up former because urgent call if the RRC that carries connects, then this priority of setting up reason is higher, resource allocation unit 903 can allow to seize the service resources of other low priorities UE, thereby can be preferably this migration request Resources allocation, again for example, if it is lower that the RRC that carries sets up the priority of reason, then second resource allocation unit 903 can be refused this migration request.Certainly, set up the reason, also can carry out resource allocation in conjunction with situations such as resource situation or user situations again, repeat no more herein except connecting according to RRC.
The 3rd transmitting element 905 is used for the result according to 903 resource allocations of described second resource allocation unit, sends migration request acknowledge message or migration failed message to described core net.If the resource allocation of migration success, then described the 3rd transmitting element 905 sends the migration request acknowledge message to described core net; If the resource allocation of migration failure, then described the 3rd transmitting element 905 sends the migration failed message to described core net.
Using target radio network controller embodiment of the present invention, to carry out detailed process and aforementioned the inventive method embodiment of resource allocation similar, repeats no more herein.
The target radio network controller that the embodiment of the invention provides, in transition process, receive the migration request message of carrying RRC establishment of connection reason that core net sends by target radio network controller, make this target radio network controller can know current wireless resource control RRC establishment of connection reason, thereby can carry out resource allocation according to this RRC establishment of connection reason, thereby can better carry out resource allocation, ensure the service request of high priority, improve resource utilization.
An alternative embodiment of the invention provides a kind of source radio network controller, is used for transition process, is about to UE and moves to the process of target radio network controller TRNC from source radio network controller SRNC.As shown in figure 10, this source radio network controller comprises:
The 4th transmitting element 1003 is used for the court verdict that moves according to described decision unit, requires message, described migration to require to carry in the message radio resource control RRC connection to core net transmission migration and sets up reason.For example, described migration requires can comprise in the message that RRC connects sets up the reason cell, and this cell can be used to carry RRC and connect and set up reason.The sub-cell that the reason cell can also be certain cell in this message is set up in this RRC connection.Wherein, described RRC connection is set up reason and can be comprised at least: urgent call (Emergency Call), caller session service (Originating Conversational Call), caller high priority signaling (Originating High Priority Signalling) or registration (Registration) or the like, the present invention does not do qualification to this.
The 4th receiving element 1005 is used to receive migration command messages or the migration preparation failed message that described core net sends.If migration is prepared successfully, then described the 4th receiving element 1005 receives the migration command messages that described core net sends; If failure is prepared in migration, failed message is prepared in the migration that then described the 4th receiving element 1005 receives described core net transmission.
Optionally, described source radio network controller can also comprise that second sets up the unit, is used to set up described RRC and connects and RAB.Promptly before 1001 judgements of described second decision unit were moved, described second sets up the unit can be used to set up described RRC connection and RAB.
Using source radio network controller embodiment of the present invention, to carry out detailed process and aforementioned the inventive method embodiment of resource allocation similar, repeats no more herein.
The source radio network controller that the embodiment of the invention provides, in transition process, source radio network controller requires message by sending the migration of carrying RRC establishment of connection reason to core net, make target radio network controller can know current wireless resource control RRC establishment of connection reason, thereby can carry out resource allocation according to this RRC establishment of connection reason, thereby can better carry out resource allocation, ensure the service request of high priority, improve resource utilization.
Through the above description of the embodiments, those skilled in the art can be well understood to the present invention and can realize by the mode that software adds essential hardware platform, can certainly all implement, but the former is better execution mode under a lot of situation by hardware.Based on such understanding, all or part of can the embodying that technical scheme of the present invention contributes to background technology with the form of software product, this computer software product can be stored in the storage medium, as ROM/RAM, magnetic disc, CD etc., comprise that some instructions are with so that a computer equipment (can be a personal computer, server, the perhaps network equipment etc.) carry out the described method of some part of each embodiment of the present invention or embodiment.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not depart from the scope of the present invention, and the claim of application documents of the present invention comprises these distortion and variation.
