Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The flow chart of the service cell selection method that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the method for the present embodiment comprises:
The access request that step 101, receiving terminal send by persistent district.
Terminal can constantly be measured the signal quality of each community searching in the time of idle condition, and resides in the best community of signal quality.Wherein, the resident community of terminal is referred to as persistent district.In the time that terminal need to be used wireless traffic, send access request by persistent district to RNC, specifically refer to by the base station in persistent district and send access request to RNC.RNC obtains the access request of terminal by persistent district, specifically refer to the access request that RNC receiving terminal sends by the base station in persistent district, and this access request comprises some information of terminal, such as terminal iidentification (such as phone number) etc.The process communicating by base station and the RNC of community due to terminal belongs to the common practise of this area, therefore for convenience of description, follow-up when relating to the base station of terminal by community and RNC and communicating, is all described as communicating by community and RNC.
In specific implementation process, the access request that terminal is initiated to RNC can be Radio Resource control (the Radio Resource Control that terminal is initiated to RNC; Referred to as: process RRC) connecting.
Step 102, according to access request, obtain the modulation system ability information of terminal.
Wherein, every money terminal all supports to use multiple different modulation system conventionally, for example: quarternary phase-shift keying (QPSK) (Quadrature Phase Shift Keying; Referred to as: QPSK), quadrature amplitude modulation (the Quadrature Amplitude Modulation of 16 kinds of symbols; Referred to as: QAM) (being 16QAM), 64QAM etc.; Use different modulation systems can reach different peak rates.The modulation system that terminal is used is got over high-order, and the service speed (comprising the speed that receives data and send data) that can reach is just higher.
Wherein, terminal can be carried the modulation system that it is supported in access request, and RNC resolves access request like this, obtains the modulation system ability information of terminal from access request.For example: terminal is supported QPSK and 16QAM modulation system simultaneously, and in access request, carried terminal is supported the parameter information of QPSK and these two kinds of modulation systems of 16QAM or directly in access request, is carried and QPSK and these two kinds of modulation identification informations that modulation systems difference is corresponding of 16QAM, then sends to RNC by persistent district.RNC receives after access request, according to the rule of making an appointment, access request is resolved, and obtains terminal and support simultaneously the information of QPSK and two kinds of modulation systems of 16QAM from access request.For example: carrying out in the process of RRC connection, the cell carrying in RRC connection setup complete message can show the modulation capability of terminal, and RNC can be known the modulation system ability information of terminal by this cell.Refer to 25.331 agreements in 3GPP standard about the entrained content of each message in RRC connection procedure and connection procedure, do not describe in detail at this.
In addition, terminal also can only be carried its mark in access request, and sends to RNC by persistent district.RNC receives after access request, can identify terminal according to the terminal iidentification in access request, then initiatively sends query statement to terminal, so that terminal is according to its modulation system ability information of the query statement active reporting of RNC.
Step 103, according to the modulation system ability information of the modulation system ability information of terminal and each community of obtaining, from each community, select Serving cell, so that terminal is by Serving cell access of radio network.
Wherein, Different Modulations is also supported to use in each community, such as QPSK, 16QAM, 64QAM etc.The common factor of the modulation system that the modulation system using in practical communication process is supported by terminal and the modulation system supported with the community that terminal connects is determined.For example: suppose community support QPSK, 16QAM and tri-kinds of modulation systems of 64QAM, but terminal is only supported QPSK modulation system, therefore, only can use this kind of modulation system of QPSK in actual use procedure.Again for example: suppose community support QPSK and two kinds of modulation systems of 16QAM, but terminal is supported QPSK, 16QAM and tri-kinds of modulation systems of 64QAM simultaneously, can use in actual use two kinds of modulation systems of QPSK and 16QAM.
In practical communication process, do not support the more community of high-order modulating if there is the more terminal access of high order modulation ability (supporting more high-order modulating), terminal can not be used the more modulation system of high-order to obtain higher service speed, therefore, in the present embodiment, RNC is simultaneously according to the modulation system ability information of the modulation system ability information of terminal and each community, from each community, select Serving cell for terminal, make terminal pass through Serving cell access of radio network.
RNC is simultaneously according to the modulation system ability information of the modulation system ability information of terminal and each community, the Serving cell of selecting from each community for terminal and the modulation system ability information of terminal are the most approaching, can make terminal give full play to its modulation capability, make terminal obtain higher service speed.
The service cell selection method of the present embodiment, RNC obtains the modulation system ability information of terminal according to the access request of terminal, and be that terminal is selected Serving cell according to the modulation system ability information of the modulation system ability information of terminal and each community simultaneously, while making terminal by Serving cell access of radio network, can give full play to its modulation system ability, obtain higher service speed, solve Serving cell that the signal quality of each community that prior art only measures based on terminal the selects problem because of the low limiting terminal modulation system of the modulation system ability ability performance of modulation system energy force rate terminal, improve the speed that terminal transmits and receive data.On the other hand, the service cell selection method of the present embodiment also can make the modulation system ability of community fully be utilized, and has improved network utilisation efficiency.
The flow chart of the service cell selection method that Fig. 2 provides for another embodiment of the present invention.As shown in Figure 2, the method for the present embodiment comprises:
Step 200, obtain the modulation system ability information of each community.
In the present embodiment, RNC first obtained the modulation system ability information of each community before the modulation system ability information that uses each community.But, the operation of obtaining is not limited in step 201, before the access request that receiving terminal sends by persistent district, that is to say, RNC also can, after receiving the access request of terminal transmission, go to obtain the modulation system ability information of each community in real time.
The present embodiment provides the execution mode of the modulation system ability information that several RNC obtain each community.A kind of mode is: RNC sends respectively inquiry request to the base station of each community, and the modulation system ability information of community, place is returned to it in the base station that requires each community; The base station of each community receives after inquiry request, knows that RNC requires it to report supported modulation system, therefore return to respectively the modulation system ability information of community, place to RNC; RNC receives the modulation system ability information of the community, place of the base station of each community returning respectively according to inquiry request.
Another kind of mode is: the base station of each community initiatively reports the modulation system ability information of community, place to RNC according to preset strategy, the base station that RNC receives each community is according to the modulation system ability information of the community, place of preset strategy active reporting, to obtain the modulation system ability information of each community.Wherein, preset strategy can be fixed time interval, and Ze Ge community can timing report modulation system ability information separately to RNC.Preset strategy can be also some conditions, and the community of for example NodeB is newly set up, the community of NodeB is deleted, the cell ability of NodeB changes, the public physic channel of NodeB and/or Common transport channel ability change etc.When Dang Ge community meets these conditions, its base station initiatively reports the modulation system ability information of community, place to RNC.
Another mode is: set up in advance the database of the modulation system ability information that stores each community, RNC, by Query Database, obtains the modulation system ability information of each community.Wherein, can set up this database by manual type, and can also upgrade database according to the variation of the modulation system ability information of each community.
The access request that step 201, receiving terminal send by persistent district.
Step 202, according to access request, obtain the modulation system ability information of terminal.
Step 203, according to the modulation system ability information of the modulation system ability information of terminal and each community of obtaining, from each community, select Serving cell, so that terminal is by Serving cell access of radio network.
Wherein, above-mentioned steps 201-step 203 can, referring to the description of above-mentioned steps 101-step 103, not repeat them here.
The service cell selection method of the present embodiment, RNC obtains the modulation system ability information of each community in advance by variety of way, for being that terminal selects Serving cell to lay the foundation according to the modulation system ability information of the modulation system ability information of each community and terminal, for the service speed that improves terminal provides guarantee.
Further, conventionally the modulation system difference that each community is supported, and in various embodiments of the present invention, RNC is that terminal is selected Serving cell according to the modulation system of each community, if the modulation system that certain community is supported does not meet the high modulation mode that terminal is supported, do not need the modulation system of Dui Gai community to upgrade, can from other communities, select to meet the community of the high modulation mode that terminal supports as its Serving cell, thereby save the modulation system of all communities the upgrade Internet resources and the upgrade cost that cause.
The flow chart of the service cell selection method that Fig. 3 provides for further embodiment of this invention.As shown in Figure 3, the method for the present embodiment comprises:
The access request that step 301, receiving terminal send by persistent district.
Wherein, above-mentioned steps 300-step 302 can, referring to the description of step 200-step 202, not repeat them here.
Conventionally be that the modulation system ability information of terminal or the modulation system ability information of community all comprise up modulation system ability information and Corticofugal Modulation of Somatosensory mode ability information.Based on this, RNC can, according to the similarity of the up modulation system ability information of the up modulation system ability information of each community and terminal, sort to the service ability of each community.RNC also can, according to the similarity of the Corticofugal Modulation of Somatosensory mode ability information of the Corticofugal Modulation of Somatosensory mode ability information of each community and terminal, sort to the service ability of each community.Further, for the service ability of more rational Dui Ge community sorts, RNC can also according to the up modulation system ability information of each community and Corticofugal Modulation of Somatosensory mode ability information respectively with the up modulation system ability information of terminal and the similarity of Corticofugal Modulation of Somatosensory mode ability information, the service ability of each community is sorted.
Wherein, the high-order modulating of supporting due to terminal has farthest determined the obtainable service speed of terminal, therefore be first whether to comprise that according to the modulation system ability information of community the high-order modulating in the modulation system ability information of terminal divides in the similarity described in various embodiments of the present invention, then the modulation capability, further reflecting according to the modulation system ability information of each community is divided.
Based on above-mentioned, the first two situation that the present embodiment sorts to the service ability of each community to above-mentioned RNC elaborates.
RNC is according to the similarity of the up modulation system ability information of the up modulation system ability information of each community and terminal, and the execution mode that the service ability of Dui Ge community sorts comprises:
Step 3031a, RNC obtain the second cell set of high up modulation system in the up modulation system ability information that the first cell set of the highest up modulation system in the up modulation system ability information that up modulation system ability information comprises terminal and up modulation system ability information do not comprise terminal from all communities.
For example: the up modulation system ability information of supposing terminal comprises: QPSK and 16QAM, the highest up modulation system is 16QAM; Suppose to have 4 communities, the up modulation system ability information of the 1st community comprises: QPSK; The up modulation system ability information of the 2nd community comprises: QPSK, 16QAM and 64QAM; The up modulation system ability information of the 3rd community comprises: QPSK and 64QAM; The up modulation system ability information of the 4th community comprises: 16QAM.RNC will get the first cell set being formed by the 2nd community and the 4th community and the second cell set being formed by the 1st community and the 3rd community by judging.That is to say, the first cell set comprises that all up modulation system ability information comprise the community of high up modulation system that terminal is supported; The second cell set is the supplementary set of the first cell set, comprises other communities except the first cell set Zhong community in all communities.
Step 3032a, RNC sort the first cell set Zhong Ge community from low to high according to up modulation capability corresponding to up modulation system ability information, obtain the first ranking results.
Wherein, the exponent number of the highest up modulation system that the up modulation system ability information of the first cell set Zhong Ge community comprises is higher, and up modulation capability (follow-up referred to as up modulation capability corresponding to community) corresponding to the up modulation system ability information of this community is just higher.
For example: the highest up modulation system of the 2nd community is 64QAM, the highest up modulation system of the 4th community is 16QAM; The exponent number of the highest up modulation system of the 2nd community is higher than the 4th community, therefore up modulation capability corresponding to the 2nd community be higher than up modulation capability corresponding to the 4th community, therefore the first ranking results that RNC obtains after to the service ability sequence of the 2nd community and the 4th community is: the 4th community, the 2nd community.
Wherein, if there is the identical situation of the up modulation capability of multiple communities in the first cell set time, sorted from high to low according to Corticofugal Modulation of Somatosensory ability corresponding to Corticofugal Modulation of Somatosensory mode ability information in the community that up modulation capability is identical.Wherein, the exponent number of the highest descending modulation system in the Corticofugal Modulation of Somatosensory mode ability information of community is higher, and Corticofugal Modulation of Somatosensory ability (follow-up referred to as Corticofugal Modulation of Somatosensory ability corresponding to community) corresponding to the Corticofugal Modulation of Somatosensory mode ability information of community is just higher.
Step 3033a, RNC sort the second cell set Zhong Ge community from high to low according to up modulation capability corresponding to up modulation system ability information, obtain the second ranking results.
For example: the highest up modulation system of the 1st community is QPSK, the highest up modulation system of the 3rd community is 64QAM; The exponent number of the highest up modulation system of the 3rd community is higher than the 1st community, therefore up modulation capability corresponding to the 3rd community be higher than up modulation capability corresponding to the 1st community, therefore the second ranking results that RNC obtains after to the service ability sequence of the 1st community and the 3rd community is: the 3rd community, the 1st community.
In like manner, if there is the identical situation of the up modulation capability of multiple communities in the second cell set time, sorted from high to low according to Corticofugal Modulation of Somatosensory ability corresponding to Corticofugal Modulation of Somatosensory mode ability information in the community that up modulation capability is identical.Wherein, the exponent number of the highest descending modulation system in the Corticofugal Modulation of Somatosensory mode ability information of community is higher, and Corticofugal Modulation of Somatosensory ability corresponding to community is just higher.
After the second ranking results is connected to the first ranking results by step 3034a, RNC, form the ranking results of the service ability to each community.
For example: RNC is by the second ranking results: the 3rd community, the 1st community are connected to the first ranking results: after the 4th community, the 2nd community, form ranking results: the 4th community, the 2nd community, the 3rd community, the 1st community, so far complete the sequence of the service ability of Liao Duige community.
RNC is according to the similarity of the Corticofugal Modulation of Somatosensory mode ability information of the Corticofugal Modulation of Somatosensory mode ability information of each community and terminal, and the execution mode that the service ability of Dui Ge community sorts comprises:
Step 3031b, RNC obtain the 4th cell set of high descending modulation system in the Corticofugal Modulation of Somatosensory mode ability information that the 3rd cell set of the highest descending modulation system in the Corticofugal Modulation of Somatosensory mode ability information that Corticofugal Modulation of Somatosensory mode ability information comprises terminal and Corticofugal Modulation of Somatosensory mode ability information do not comprise terminal from all communities.
For example: the Corticofugal Modulation of Somatosensory mode ability information of supposing terminal comprises: QPSK and 16QAM, the highest descending modulation system is 16QAM; Suppose to have 4 communities, the Corticofugal Modulation of Somatosensory mode ability information of the 1st community comprises: QPSK; The Corticofugal Modulation of Somatosensory mode ability information of the 2nd community comprises: QPSK, 16QAM and 64QAM; The Corticofugal Modulation of Somatosensory mode ability information of the 3rd community comprises: QPSK and 64QAM; The Corticofugal Modulation of Somatosensory mode ability information of the 4th community comprises: 16QAM.RNC will get the 3rd cell set being formed by the 2nd community and the 4th community and the 4th cell set being formed by the 1st community and the 3rd community by judging.That is to say, the 3rd cell set comprises that all Corticofugal Modulation of Somatosensory mode ability information comprise the community of high descending modulation system that terminal is supported; The 4th cell set is the supplementary set of the 3rd cell set, comprises other communities except the 3rd cell set Zhong community in all communities.
Step 3032b, RNC sort the 3rd cell set Zhong Ge community from low to high according to Corticofugal Modulation of Somatosensory ability corresponding to Corticofugal Modulation of Somatosensory mode ability information, obtain the 3rd ranking results.
Wherein, the exponent number of the highest descending modulation system that the Corticofugal Modulation of Somatosensory mode ability information of the 3rd cell set Zhong Ge community comprises is higher, and Corticofugal Modulation of Somatosensory ability (follow-up referred to as Corticofugal Modulation of Somatosensory ability corresponding to community) corresponding to the Corticofugal Modulation of Somatosensory mode ability information of this community is just higher.
For example: the highest descending modulation system of the 2nd community is 64QAM, the highest descending modulation system of the 4th community is 16QAM; The exponent number of the highest descending modulation system of the 2nd community is higher than the 4th community, therefore Corticofugal Modulation of Somatosensory ability corresponding to the 2nd community be higher than Corticofugal Modulation of Somatosensory ability corresponding to the 4th community, therefore the 3rd ranking results that RNC obtains after to the service ability sequence of the 2nd community and the 4th community is: the 4th community, the 2nd community.
Wherein, if there is the identical situation of the Corticofugal Modulation of Somatosensory ability of multiple communities in the 3rd cell set time, sorted from high to low according to up modulation capability corresponding to up modulation system ability information in the community that Corticofugal Modulation of Somatosensory ability is identical.Wherein, the exponent number of the highest up modulation system in the up modulation system ability information of community is higher, and up modulation capability corresponding to community is just higher.
Step 3033b, RNC sort the 4th cell set Zhong Ge community from high to low according to Corticofugal Modulation of Somatosensory ability corresponding to Corticofugal Modulation of Somatosensory mode ability information, obtain the 4th ranking results.
For example: the highest descending modulation system of the 1st community is QPSK, the highest descending modulation system of the 3rd community is 64QAM; The exponent number of the highest descending modulation system of the 3rd community is higher than the 1st community, therefore Corticofugal Modulation of Somatosensory ability corresponding to the 3rd community be higher than Corticofugal Modulation of Somatosensory ability corresponding to the 1st community, therefore the second ranking results that RNC obtains after to the service ability sequence of the 1st community and the 3rd community is: the 3rd community, the 1st community.
In like manner, if there is the identical situation of the Corticofugal Modulation of Somatosensory ability of multiple communities in the 4th cell set time, sorted from high to low according to up modulation capability corresponding to up modulation system ability information in the community that Corticofugal Modulation of Somatosensory ability is identical.Wherein, the exponent number of the highest up modulation system in the up modulation system ability information of community is higher, and up modulation capability corresponding to community is just higher.
After the 4th ranking results is connected to the 3rd ranking results by step 3034b, RNC, form the ranking results of the service ability to each community.
For example: RNC is by the 4th ranking results: the 3rd community, the 1st community are connected to the 3rd ranking results: after the 4th community, the 2nd community, form ranking results: the 4th community, the 2nd community, the 3rd community, the 1st community, so far complete the sequence of the service ability of Liao Duige community.
RNC is simultaneously according to the similarity of the similarity of up modulation system ability information and Corticofugal Modulation of Somatosensory mode ability information, the execution mode that the service ability of Dui Ge community sorts can be: RNC is first according to the similarity of the up modulation system ability information of the up modulation system ability information of each community and terminal, the service ability of Dui Ge community sorts, there are multiple communities of identical similarity for up modulation system ability information and the up modulation system ability information of terminal, can sort according to the similarity of the Corticofugal Modulation of Somatosensory mode ability information of the Corticofugal Modulation of Somatosensory mode ability information of multiple communities and terminal, and obtain final ranking results.Wherein, the concrete operations of two minor sorts can be referring to the description to first two situation before.
In addition, RNC is simultaneously according to the similarity of the similarity of up modulation system ability information and Corticofugal Modulation of Somatosensory mode ability information, the execution mode that the service ability of Dui Ge community sorts can also be: RNC is first according to the similarity of the Corticofugal Modulation of Somatosensory mode ability information of the Corticofugal Modulation of Somatosensory mode ability information of each community and terminal, the service ability of Dui Ge community sorts, there are multiple communities of identical similarity for Corticofugal Modulation of Somatosensory mode ability information and the Corticofugal Modulation of Somatosensory mode ability information of terminal, can sort according to the similarity of the up modulation system ability information of the up modulation system ability information of multiple communities and terminal, and obtain final ranking results.
For RNC, simultaneously according to the similarity of the similarity of up modulation system ability information and Corticofugal Modulation of Somatosensory mode ability information, the execution mode that the service ability of Dui Ge community sorts can have multiple implementation, and this is no longer going to repeat them.In this explanation, the similarity of the modulation system ability information of community and the modulation system ability information of terminal, except above-mentioned definition, can also refer to the size of the common factor of the modulation system that modulation system that community is supported and terminal support.For example: the quantity that modulation system that the modulation system that community is supported is supported with terminal is identical is more, illustrates that similarity is higher.Similarity can also be other definition in addition.For the implementation sorting according to the service ability of the similarity Dui Ge community under other definition, principle is identical with aforesaid way, therefore be not described in detail.
Concrete, RNC carries out access judgement in primary community place to terminal in ranking results, specifically judges user corresponding to terminal access authority, the situation etc. that meets in primary community; If access judgement is passed through, in ranking results, be Serving cell in primary community; If access judgement is not passed through, RNC continues in deputy community place, terminal to be carried out to access judgement in ranking results, the like until access judgement is passed through, RNC obtains access and adjudicates the community of passing through, and access is adjudicated to the Serving cell as terminal, the community passed through.
For example: for the ranking results sorting according to the service ability of up modulation system ability information similarity Dui Ge community for RNC, first RNC carries out access judgement at the 4th community place to terminal, if access judgement is passed through, the 4th community is the Serving cell of terminal; If access judgement is not passed through, RNC continues, at the 2nd community place, terminal is carried out to access judgement, if access judgement is passed through, the 2nd community is the Serving cell of terminal; If access judgement is not passed through, RNC continues, at the 3rd community place, terminal is carried out to access judgement, if access judgement is passed through, the 3rd community is the Serving cell of terminal, adjudicate until get access the community of passing through, Bing Jianggai community is as the Serving cell of terminal.
RNC is after terminal is obtained Serving cell, and terminal, by Serving cell access of radio network, completes wireless traffic.

The service cell selection method of the present embodiment, RNC is before carrying out sorting operation according to the service ability of the modulation system ability information Dui Ge community of the modulation system ability information He Ge community of terminal, whether the modulation system ability information that first judges persistent district comprises the high modulation mode in the modulation system ability information of terminal, first judge whether the modulation system of supporting persistent district can meet the high modulation mode that terminal is supported, if met, selecting persistent district is Serving cell, both can save the operation that Dui Ge community service ability sorts, reduce the burden of RNC, can get again modulation system and signal quality and be optimum Serving cell, further improve the service speed that terminal is obtained, improve the service quality of wireless traffic.
Further illustrate, in the various embodiments described above, Jun Weiduige community limits, and wherein comparatively preferably selects the community that has same transmitting antenna (with persistent district under same sector) with persistent district as the various embodiments described above Zhong Ge community.Wherein, signal quality between Xia Ge community, same sector is more similar, and because persistent district is the good community of signal quality that terminal is selected, that is to say with persistent district all better at the signal quality of Xia Ge community, same sector, RNC can consider signal quality in the process of selecting Serving cell with persistent district in Xia Ge community, same sector for terminal, just can select modulation system ability and signal quality all preferably community as the Serving cell of terminal, thereby make terminal and Serving cell can better bring into play ability separately.In addition, because the number of cells under RNC is numerous, and be not that each community can cover terminal, therefore from persistent district Xia Ge community, same sector be terminal select Serving cell, the operation that RNC processes not covering the community of terminal can be reduced, the resource of RNC can be saved greatly.
Conventionally in the time being each cell allocation mark (ID), the numbering of sector, place, Hui Jiang community adds, therefore RNC selects from numerous communities with persistent district at a kind of execution mode of Xia community, same sector be: RNC can directly obtain the numbering of sector, place, persistent district from the mark of persistent district, then select the community identical with the numbering of sector, place, persistent district according to the sector label in the mark of each community.In addition, because RNC knows the much information of each community conventionally, therefore for RNC by other means (for example, from other information) obtain under the covering of any root antenna (namely sector) of each community in which base station.Under the announcement of above-mentioned execution mode, those skilled in the art can realize other modes.
For more clearly understanding the various embodiments described above, below be described further by detailed example.
Taking WCDMA or HSPA network as example, suppose in this network, to have 4 communities, be respectively Cell1, Cell2, Cell3, Cell4.Cell1, Cell2, Cell3, Cell4, for using the community of the same antenna (namely under same sector), have similar signal strength signal intensity.RNC obtains and has recorded the modulation capability of the Cell of all use same antennas in advance, specifically comprises: the modulation system ability information of Cell1 comprises descending support QPSK and 16QAM, up support QPSK.The modulation system ability information of Cell2 comprises descending support QPSK, 16QAM and 64QAM, up support QPSK.The modulation system ability information of Cell3 comprises: descending support QPSK, 16QAM and 64QAM, up support QPSK and 16QAM.The modulation system ability information of Cell4 comprises descending support QPSK, up support QPSK.
Suppose that UE resides in Cell1 and request access, the highest descending modulation system of UE is 64QAM, and the highest up modulation system is QPSK.In the present embodiment, select Serving cell with the highest descending modulation system of paying the utmost attention to UE.The highest descending modulation system of supposing Cell1 is 16QAM, can not meet the modulation capability of UE.In prior art scheme, UE will access at Cell1, and adopt 16QAM modulation system, and this can not bring into play the modulation capability of UE, and support Cell2 and the Cell3 of 64QAM not to be used effectively.
And in various embodiments of the present invention, UE is in Cell1 request access, and report the modulation capability of UE by access request.For example: the RRC connection of UE in RRC connection building process set up in terminal wireless access capability (the UE radio access capability) parameter in (RRC CONNECTION SETUP COMPLETE) and reported its modulation capability, can be referring to the description in 3GPP 25.331 about this process, in addition, UE also can take other process to report its modulation capability.The modulation capability that UE reports comprises that its Corticofugal Modulation of Somatosensory mode of supporting comprises QPSK, 16QAM and 64QAM, and its up modulation system of supporting is QPSK.
Then, RNC judges whether the modulation system ability information of Cell1 meets the modulation capability of UE, mainly refers to the highest descending modulation system 64QAM that whether comprises UE in the Corticofugal Modulation of Somatosensory mode that RNC judges that Cell1 supports.RNC show that Cell1 does not meet the modulation capability of UE.
Then, RNC pair uses same antenna Ge community to carry out the prioritization based on modulation capability with Cell1; Service ability based on Corticofugal Modulation of Somatosensory ability Dui Ge community sorts in the present embodiment, and ranking results is: Cell3, Cell2, Cell1, Cell4.Wherein, Cell3 and Cell2 belong to the community of the highest descending modulation system 64QAM that Corticofugal Modulation of Somatosensory mode comprises UE; And because the Corticofugal Modulation of Somatosensory ability of Cell3 and Cell2 is identical, therefore Cell3 and Cell2 are sorted according to the up modulation capability of Cell3 and Cell2, because the highest up modulation system of Cell3 is 16QAM, and the highest up modulation system of Cell2 is QPSK, therefore the up modulation capability of Cell3 is greater than the up modulation capability of Cell2, therefore being Cell3, ranking results has precedence over Cell2.Wherein, Cell1 and Cell4 belong to the community of the highest descending modulation system 64QAM that Corticofugal Modulation of Somatosensory mode does not comprise UE; And because the highest descending modulation system of Cell1 is 16QAM, and the highest descending modulation system of Cell4 is QPSK, therefore the Corticofugal Modulation of Somatosensory ability of Cell1 is greater than the Corticofugal Modulation of Somatosensory ability of Cell4, has precedence over Cell4 therefore ranking results is Cell1.RNC combines two kinds of ranking results, obtains final ranking results: Cell3, Cell2, Cell1, Cell4.
Afterwards, RNC is according to the sequencing of the service ability of each community, and Ge community place carries out access judgement to UE successively.Wherein, priority is up to Cell3, RNC adopts redirected mode that UE is redirected to Cell3 from Cell1, or RNC adopts the mode that alien frequencies switches that UE is switched to Cell3 from Cell1, or RNC control UE adopt directed retry mode by Cell3 initiates access, RNC carries out access judgement at Cell3 place to UE.When in the time that the access judgement at Cell3 place is passed through, determine that Cell3 is Serving cell, UE accesses by Cell3.When in the time that the access judgement at Cell3 place is not passed through, RNC continue to adopt be redirected, alien frequencies switches or the mode such as directed retry forwards UE to Cell2 by Cell3, and at Cell2 place, UE is carried out to access judgement, the like, until find access to adjudicate the community of passing through, UE completes access by this community.
Wherein, RNC continue to adopt be redirected, alien frequencies switches or the mode such as directed retry forwards UECong mono-community to another community execution mode belongs to prior art, specifically can, referring to the description of corresponding specification in 3GPP, not repeat them here.
In sum, in the various embodiments described above of the present invention, RNC selects Serving cell according to the similarity of the modulation system ability information of the modulation system ability information He Ge community of terminal, selected Serving cell can make terminal farthest bring into play its modulation system ability, solve terminal and be subject to the modulation system ability of Serving cell cannot bring into play the problem of modulation system ability compared with low restriction, improved the service speed that terminal obtains; In addition, compared with the scheme of modulation system of the each community of upgrading, also there is the advantage of saving upgrade cost and saving Internet resources.
