With reference to Fig. 1, be a kind of flow chart of embodiment of the invention wireless resource allocation methods, may further comprise the steps:
Particularly, can connect existing RRC and set up request message and expand, increase multiband ability information parameter therein, and with this parameter as optional parameters, if this parameter does not occur, can be defaulted as UE and only support main carrier place frequency range.
For the UE that supports tdd mode, this parameter can be following four kinds of value: a+f, a+e, e+f, a+e+f.Certainly, consider follow-up development, can also reserve other values for it.
Particularly, can preferentially to select in the sub-district, described UE place the corresponding carrier wave of multiband ability with described UE be that described UE distributes DPCH to RNC; If in the sub-district, described UE place with the corresponding carrier wave of multiband ability of described UE under frequency range do not have surplus resources, then selecting in the adjacent sub-district with the overlapping covering in sub-district, described UE place with the corresponding carrier wave of UE multiband ability is that described UE distributes DPCH.Certainly, can also preferentially to select the carrier wave of the different frequency range of main carrier of sub-district, described UE place be that described UE distributes DPCH to RNC; If the different frequency range of described main carrier does not have surplus resources, the carrier wave of then selecting main carrier place frequency range is that described UE distributes DPCH.Certainly, other methods of salary distribution can also be arranged.
In selecting sub-district, described UE place, be described UE when distributing the required carrier resource of DPCH, can preferentially select the surplus resources of frequency range under the main carrier of described UE with the corresponding carrier wave of multiband ability of described UE; If frequency range does not have surplus resources under the described main carrier, then select the carrier wave of other frequency ranges.
In above-mentioned flow process, can further include following steps:
After the resource allocation success, RNC sends the RRC connection to described UE and sets up message, is included as the carrier resource that described UE distributes in the described message.
In addition, in above-mentioned flow process, can further include following steps:
(1) RNC sends to the base station with the multiband ability information of described UE, and particularly, can set up message or Radio Link by radio link reconfiguration message or Radio Link increases message etc., and the multiband ability information of described UE is sent to the base station;
(2) RNC receives the response message that the base station sends, comprising the base station in the described response message is the carrier resource that the packet switch domain service of described UE distributes according to the multiband ability information of described UE, message when sending to the multiband ability information of the described UE in base station with RNC is corresponding, and the response message that the base station that RNC receives sends can be: radio link reconfiguration response message or Radio Link set up response message or Radio Link increases response message etc.;
(3) RNC is that the carrier resource that the packet switch domain service of described UE distributes sends to described UE with the base station, particularly, can set up message by radio bearer, perhaps other message, such as radio bearer reconfiguration message etc., be that the carrier resource that the packet switch domain service of described UE distributes sends to described UE with the base station.
Further describe embodiment of the invention wireless resource allocation methods below respectively for example.
Example 1: suppose to exist in the sub-district a plurality of carrier waves, these carrier waves belong to different frequency ranges, such as, main carrier is a frequency range, auxilliary carrier wave is a frequency range+f frequency range.
UE at first initiates RRC to network and connects the request of foundation under situations such as initiation business or the paging of response to network side, and the multiband ability of wherein having carried UE supposes that the multiband ability information that UE carries is " a+f ".
RNC is the UE distributing radio resource after receiving that request message is set up in the RRC connection.
Particularly, if the carrier wave of a frequency range has surplus resources, the carrier wave of then preferentially selecting a frequency range is that UE distributes the required carrier resource of DPCH; If the carrier wave of a frequency range does not have surplus resources to insert the user, then select the carrier wave of f frequency range for UE.Resource allocation success back is set up message by the RRC connection and is notified the user with resource allocation result.
Example 2: suppose only to exist among the A of sub-district single auxilliary carrier wave, and to belong to same frequency range with main carrier be frequency range a, adjacent sub-district B and the overlapping covering of sub-district A of sub-district A simultaneously, the carrier wave of sub-district B belongs to frequency range f.So-called overlapping covering is meant that the physics coverage of sub-district B is identical with the physics coverage of sub-district A, and perhaps the physics coverage of sub-district B is above the physics coverage of sub-district A.The overlapping covering of B and A means that RNC can switch to sub-district B with the user among the A of sub-district under the prerequisite that does not rely on the pilot measurement result.
UE initiates RRC at sub-district A and connects the request of foundation, and the multiband ability of wherein having carried UE supposes that the multiband ability information that UE carries is " a+f ".
RNC receives that RRC connects and sets up after the request message, is the UE distributing radio resource.
Particularly, if sub-district A has surplus resources to insert the user, then RNC is that UE selects sub-district A and carries out resource allocation; If sub-district A does not have surplus resources to insert the user, then RNC is that UE selects sub-district B and carries out resource allocation.After the resource allocation success, set up message by the RRC connection and notify the user resource allocation result.
Certainly, RNC is not limited in the mode of above-mentioned two examples when carrying out resource allocation, also can with the UE resource selection mode of making an appointment, can also be by network side resource allocation selection mode.
Such as, in above-mentioned example 2, though sub-district A has available resources, network strategy is configured to the sub-district of the preferred f frequency range of multiband UE, and then RNC is preferably the resource that UE distributes sub-district B.
As seen, utilize the wireless resource allocation methods of the embodiment of the invention, can make RNC come the distributing carrier wave resource, make and load balancing between each frequency range improved call completing rate according to UE frequency range support situation.
UE is when using HSDPA or HSUPA scheduling resource, and the employed physical resource of UE carries out Real-Time Scheduling by the base station.In embodiments of the present invention, if UE has the MIMO ability, then the base station can distribute the resource of a plurality of frequencies to use to UE according to the multiband ability information of UE.
As shown in Figure 2, be the another kind of flow chart of embodiment of the invention wireless resource allocation methods, may further comprise the steps:
Particularly, the base station can obtain the multiband ability information of UE in several ways, such as, by the radio link reconfiguration message of RNC transmission; Perhaps the Radio Link that sends by RNC is set up message; Perhaps the Radio Link that sends by RNC increases the multiband ability information that message is obtained UE.
The radio link reconfiguration message that sends with RNC is an example, can expand existing radio link reconfiguration message, increase multiband ability information parameter therein, and with this parameter as optional parameters, if this parameter does not occur, can be defaulted as UE and only support main carrier place frequency range.
Similar to the expansion of above-mentioned other existing message and above-mentioned expansion to existing radio link reconfiguration message, be not described in detail at this.
Particularly, can preferentially select with the light carrier wave of the corresponding load of multiband ability of described UE be the required carrier resource of described UE allocation packets territory service dispatching.
Certainly, the embodiment of the invention is not limited in this resource distribution mode, can also with the UE resource selection mode of making an appointment, perhaps by network side resource allocation selection mode.
In above-mentioned flow process, can further include following steps:
The base station will be notified to RNC for the carrier resource that described UE distributes by the radio link reconfiguration response message.
When UE initiation packet territory is professional, at first sets up RRC and connect, set up radio bearer afterwards again.Need to prove that in embodiments of the present invention, UE connects in the request of foundation or the RRC connection setup complete message at RRC can carry the multiband ability information.Like this, RNC can connect the multiband ability information of obtaining UE when setting up at RRC, also can connect the multiband ability information that obtains UE after foundation is finished at RRC.RNC is notified to the base station with the multiband ability information of the UE of acquisition, makes the base station when carrying out HSDPA or HSUPA scheduling, and can come according to the ability information of UE is that UE distributes suitable carrier resource.
Further describe embodiment of the invention wireless resource allocation methods below respectively for example.
Example 3: suppose to exist in the sub-district a plurality of carrier waves, these carrier waves belong to different frequency ranges, such as, main carrier is a frequency range, auxilliary carrier wave is a frequency range+f frequency range.
UE initiation packet territory business, RNC is when setting up radio bearer, and for downlink business and the uplink service of UE distributes HSDPA and HSUPA resource respectively, signaling is used the DPCH carrying.
RNC is by the allocation of radio resources advisory base station of radio link reconfiguration message with UE, and the ability information of having carried UE in described radio link reconfiguration message comprises the MIMO ability information of UE, the multiband ability information of UE.
If UE does not support the MIMO ability, promptly can only use the resource of single carrier wave, then the HSDPA resource and the HSUPA resource of DPCH place carrier wave only can be distributed in the base station.If UE supports the MIMO ability, then the base station can be according to the load condition of each carrier wave or according to the operation strategy (such as the carrier wave of the preferred f frequency range of terminal) of network, for UE distributes employed HSDPA resource and HSUPA resource (HSDPA resource/HSUPA resource place carrier wave can be different from DPCH place carrier wave).
The multiband ability information of supposing UE in this example is " a+f ", then the base station obtains the multiband ability information of UE according to the radio link reconfiguration message received, according to the multiband ability information of UE and the resource that is preferably UE scheduling f carrier wave according to the operation strategy of network.
Then, the base station will be notified to RNC for the carrier resource that described UE distributes by the radio link reconfiguration response message.
RNC receives after the radio link reconfiguration response message, sets up message by radio bearer, and the allocation of radio resources advisory UE with UE specifically comprises: RNC is the DPCH resource that UE distributes, and the base station is HSDPA and HSUPA carrier resource that UE distributes.
Example 4: have a plurality of carrier waves in the sub-district, these carrier waves belong to different frequency ranges, such as, main carrier is a frequency range, auxilliary carrier wave is a frequency range+f frequency range.
UE initiation packet territory business, RNC is that downlink signaling/business and the up signaling/business of UE distributed HSDPA and HSUPA resource respectively, signaling does not re-use the DPCH carrying.
RNC is by the allocation of radio resources advisory base station of radio link reconfiguration message with UE, and the ability information of wherein also having carried UE comprises the MIMO ability information of UE, the multiband ability information of UE.
If UE does not support MIMO, then the base station is in conjunction with the load condition of each carrier wave or according to the operation strategy (such as the carrier wave of preferred f frequency range) of network, HSDPA resource/HSUPA the resource (can select the carrier wave of a frequency range, perhaps the carrier wave of f frequency range) of distributing a carrier wave to UE.If UE supports MIMO, then the HSDPA resource/HSUPA resource of a plurality of carrier waves can be distributed in conjunction with the load condition of other carrier waves in the base station for UE in the band limits that UE supported.
The multiband ability information of supposing UE in this example is " a+f ", then the base station obtains the multiband ability information of UE according to the radio link reconfiguration message received, preferentially dispatches on the light carrier wave of load according to the multiband ability information of UE and the load condition of each carrier wave.
Then, the base station will be notified to RNC for the carrier resource that described UE distributes by the radio link reconfiguration response message.
RNC receives after the radio link reconfiguration response message, sets up message by radio bearer, with the allocation of radio resources advisory UE of UE.
Need to prove that UE is when using HSDPA and HSUPA resource, the RF capabilities of UE may change.Therefore, in the wireless resource allocation methods of the embodiment of the invention, after the RF capabilities of UE changed, UE upgraded the multiband ability information of carrying UE in the indication to RNC reporting ability information updating indication in this ability information.
RNC receives after the ability information renewal indication of UE, by the new multiband ability information of wireless links reconfiguration course informing base station UE.
