Description
Technical field
The present invention relates to moving communicating field, particularly the access technology at random in the mobile communication system.
Background technology
Along with being showing improvement or progress day by day of mobile communication technology, the sharp increase of mobile subscriber's quantity has brought new pressure to wireless communication system, particularly the access control technology in the wireless communication system is had higher requirement.The access control technology is a kind of control method that realizes in the wireless communication system subscriber equipment (User Equipment is called for short " UE ") access wireless channel.
Below the access control technology in the wireless communication system is made brief description.In wireless communication system, UE is in each neighbor cell when mobile, and after entering completing place, some sub-districts and registering, UE just resides in this sub-district, and enters idle condition, and this sub-district also just is called the current area of UE.Under idle condition, if UE carries out the subdistrict position renewal process, perhaps need the paging that the sub-district is come is replied, perhaps need to set up calling with other user, comprise service request, the request of sending SMS message etc., then UE can send insert request to the current area base station.Need to prove that random access procedure is initiated by this UE.UE sends the request of access to cell base station on Random Access Channel, carry out access exploration.Receive the access request of UE when network side after, just return letter road assignment messages to UE on a common signal channel, UE and base station are mutual at the enterprising line data of particular channel that distributes then.Need to prove that also the random access procedure that UE initiates is the access-in resource according to the current area base station, and finish according to specific algorithm.UE selects access slot in available access-in resource, this selection is at random, and the base station is after receiving the access exploration of UE then, and cell base station just sends one and inserts Indication message to UE, shows whether current UE inserts success.Get nowhere if insert at random, UE then can't carry out data interaction with current area so, can not finish the function of conversation or transfer of data.
In wireless communication system, UE initiate to initiate has access to different reasons at random, mainly is divided into two kinds: the information that response paging and UE start fully, and the promptly aforesaid paging that the sub-district is come is replied, with set up calling with other user, comprise service request, send SMS message the request etc.If there are two or more UE to send access information simultaneously, the signal of air interface then can be obscured, and will cause correctly demodulation transmitting terminal signal of receiving terminal, and this just becomes the conflict that inserts at random.Because the mode that inserts is the process of initiating to insert in the mode of probe at random, therefore can modulate with mutually orthogonal code character the content of probe in order to reduce to conflict.The generating mode of access sequence has a lot, such as Walsh sequence, Golay sequence etc.The Walsh sign indicating number be one group by 0,1 or 1 ,-1 sign indicating number sequence of forming, length is 2 n power.In case the dimension of Walsh sign indicating number determines that the combination of all Walsh sign indicating numbers is promptly determined.Walsh sign indicating numbers such as 1024 dimensions have 1024 kinds of different sign indicating number sequences, and the length of each sequence is 1024 also, can be described as 1024 code spaces, quadrature all between per two sign indicating number sequences.
Though inserting at random of different UEs with different access sequence modulation, even make that transmitting random accessing message simultaneously also can be received proper really reception, still, if different UE adopts same access sequence modulation simultaneously, then also will cause the phase mutual interference, and make receiving terminal can't solve useful information.Initiate the different reasons that insert at random according to UE, the conflict that different UE can be adopted simultaneously same access sequence modulation to cause is divided into conflict between the UE that respond paging, respond paging UE and the conflict between the UE of conflicting, start between the UE of starting.Therefore, then need avoid UE to select same access sequence for use in order to improve the performance that inserts at random at same delivery time as far as possible.
At present, in the access at random of international institute of electrical and electronic engineers (Institute of Electrical and ElectronicsEngineers is called for short " IEEE ") 802.20, used the Walsh sign indicating number of 1024 dimensions that the content of access probe is modulated.The call number of 1024 code spaces is 0-1023, wherein call number be 0-17 kept for that Active Set do to switch, power control and time adjustment use.Call number is that leaving for when UE sends out access probe of 18-1023 (totally 1006) used.The access probe that sends comprises that response paging and UE initiate the probe of cause values such as beginning calling.
Wherein, the spendable Walsh sign indicating number of UE is divided into 9 groups, and is as shown in table 1, wherein the corresponding access sequence information that comprises with these nine groups of row of 1 to 9 sequence number of the partitionNsize of each row (grouping size), wherein the definition of the value of S1, S2 and S3 is as shown in table 2, floor (N wherein
ACMPNumSequence/ 18) be to constant N
ACMPNumSequenceDivided by 18 round numbers downwards then.Constant N

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is, to can be used for the access sequence grouping of random access probe, sets up the corresponding relation of access sequence group and QoS information in advance, and preserves this corresponding relation respectively in UE side and network side.UE is when responding paging and/or initiatively making a call, according to or the part from corresponding access sequence group, select an access sequence to be used for random access probe at random according to QoS information, the base station basis is from the access sequence in the random access probe of this UE, search and obtain the affiliated access sequence group of this access sequence, with the pairing QoS information of this access sequence group as the pairing QoS information of this access sequence, thereby know the QoS information of this calling fast.
More than core of the present invention has been done simple declaration, below according to this principle, accidental access method in the first execution mode mobile communication system of the present invention is described in detail.
As shown in Figure 2, in step 210, UE is that random access probe is selected access sequence according to QoS information and forward channel quality when responding paging and/or initiatively making a call.Wherein, access sequence can be an orthogonal code.
Specifically, according to QoS information and forward channel quality the access sequence that can be used for random access probe is divided into groups in advance, each group inserts sequence corresponding to a kind of QoS information and forward channel quality.Wherein, QoS information comprises the user gradation and/or the grade of service.If initiatively initiate paging, UE knows the business that will initiate, and then QoS information can be the user gradation and the grade of service.When the business of initiating is mixed service, can be with the grade of the business that the grade of service is the highest in the mixed service grade as the business of this initiation; Perhaps, every business in the mixed service is carried out aggregative weighted according to weight separately, the grade that obtains with weighted calculation is as the grade of the business of this initiation.When the business of initiating was urgent call, UE can be according to one group of special access sequence of agreement selection in advance.Such as UE can judge that according to the warning number 110 of user's input this business is urgent call, then according to one group of special higher access sequence of the pairing grade of service of agreement selection in advance.
If the response paging, then UE possibly can't know what business the calling party will initiate, so QoS information can only be user gradation.The user gradation and the grade of service can set in advance in UE.If the UE of response paging can't obtain QoS information from beep-page message, then this UE can or select access sequence at random according to user gradation, the current information that has of this UE, the method for arranging in advance.
Table 4 is the example that random access probe is selected access sequence for UE according to QoS information and forward channel quality, according to the forward channel quality access sequence is divided three classes, each class access sequence further is divided into three groups according to QoS information, therefore, all access sequences that can be used for random access probe divide altogether for the 3*3=9 group and insert sequence.The grouping of access sequence and every group of corresponding relation that inserts sequence and QoS information and forward channel quality can be realized respectively according to the algorithm that presets by UE and base station, perhaps, realize back notice UE by the base station, perhaps, by after the realization of base station relevant parameter being delivered to UE, this UE realizes according to the algorithm that presets.If realize back notice UE by the base station, then this base station can be by the signaling method of system message broadcast mode or configuring negotiation, and perhaps both compound modes are notified UE.And, need in UE and network side, to preserve respectively every group of corresponding relation that inserts sequence and QoS information and forward channel quality.In the present embodiment, for convenience of explanation, access sequence is divided for the 3*3=9 group inserts sequence, but in actual applications, access sequence can be divided into the N*M group and insert sequence.
| The forward channel quality | QoS information | ||
| 1 | 2 | 3 | |
| 1 | 1 | 2 | 3 |
| 2 | 4 | 5 | 6 |
| 3 | 7 | 8 | 9 |
Table 4
When UE in the response paging and/or when initiatively making a call, this UE selects an access sequence group according to QoS information and forward channel quality from 9 access sequence groups, and then selects an access sequence to be used for this random access probe from this group at random.Because QoS information and the forward channel quality of each UE can present certain even distribution characteristics, therefore, if UE is when responding paging and/or initiatively making a call, select to be used for the access sequence of random access probe according to QoS information and forward channel quality, can effectively avoid taking place the situation of access interference at random.
Then, enter step 220, UE sends random access probe to network side.
Then, enter step 230, the base station of network side is detected from the access sequence in the random access probe of this UE.
Then, enter step 240, the base station of network side obtains the QoS information of this calling.Specifically, the base station according to detected from the access sequence in the random access probe of this UE, the every group of corresponding relation that inserts sequence and QoS information and forward channel quality that passes through to be preserved, search and obtain the affiliated access sequence group of this access sequence, with the pairing QoS information of this access sequence group and forward channel quality as pairing QoS information of this access sequence and forward channel quality, thereby obtain the QoS information of this calling and the forward channel quality of this UE.
Then, enter step 250, the access of this UE is refused or accepts in the base station of network side in access grant message according to the forward channel quality of QoS information and this UE.Because UE has passed to network side with the QoS information of calling out apace by the random access probe that sends, and the user gradation and/or the grade of service have been comprised in this QoS information, make network side can adopt more reasonably access control mechanism and mechanism of permitting the entrance, thereby more reasonably distribute access-in resource.
What deserves to be mentioned is that network side can set in advance the functional switch of QoS, and the mode that the state of this functional switch is broadcasted by configuring negotiation signaling method or system message is notified to UE.If the functional switch of UE or QoS is in opening, be that random access probe is selected access sequence then according to QoS information and forward channel quality, otherwise, forbid that according to QoS information and forward channel quality be that random access probe is selected access sequence.
The base station can be accepted or the refusal business fast by the implicit information of access sequence.
The accidental access method and first execution mode are roughly the same in the second execution mode mobile communication system of the present invention, its difference only is, in the first embodiment, UE is that random access probe is selected access sequence according to QoS information and forward channel quality, and in the present embodiment, UE is that random access probe is selected access sequence according to QoS information, forward channel quality and request grade.Wherein, access sequence can be an orthogonal code.
Specifically as shown in Figure 3, in step 310, UE is that random access probe is selected access sequence according to QoS information, forward channel quality and request grade when responding paging and/or initiatively making a call.
Specifically, according to QoS information, forward channel quality with corresponding to the request grade of metadata cache quantity the access sequence that can be used for random access probe is divided into groups in advance, each group inserts sequence corresponding to a kind of QoS information, forward channel quality and request grade.Wherein, QoS information comprises the user gradation and/or the grade of service.If initiatively initiate paging, UE knows the business that will initiate, and then QoS information can be the user gradation and the grade of service.When the business of initiating is mixed service, can be with the grade of the business that the grade of service is the highest in the mixed service grade as the business of this initiation; Perhaps, every business in the mixed service is carried out aggregative weighted according to weight separately, the grade that obtains with weighted calculation is as the grade of the business of this initiation.When the business of initiating was urgent call, UE can be according to one group of special access sequence of agreement selection in advance.Such as UE can judge that according to the warning number 110 of user's input this business is urgent call, then according to one group of special higher access sequence of the pairing grade of service of agreement selection in advance.
If the response paging, then UE possibly can't know what business the calling party will initiate, so QoS information can only be user gradation.The user gradation and the grade of service can set in advance in UE.If the UE of response paging can't obtain QoS information from beep-page message, then this UE can or select access sequence at random according to user gradation, the current information that has of this UE, the method for arranging in advance.
Table 5 is the example that random access probe is selected access sequence for UE according to QoS information, forward channel quality and request grade, according to the forward channel quality access sequence is divided three classes, each class access sequence further is divided into three groups according to the request grade, in each group, be divided into three groups according to QoS information again, therefore, all access sequences that can be used for random access probe divide altogether for the 3*3*3=27 group and insert sequence.The grouping of access sequence and every group of corresponding relation that inserts sequence and QoS information, forward channel quality and request grade can be realized respectively according to the algorithm that presets by UE and base station, perhaps, realize back notice UE by the base station, perhaps, by after the realization of base station relevant parameter being delivered to UE, this UE realizes according to the algorithm that presets.If realize back notice UE by the base station, then this base station can be by the signaling method of system message broadcast mode or configuring negotiation, and perhaps both compound modes are notified UE.And, need in UE and network side, to preserve respectively every group of corresponding relation that inserts sequence and QoS information, forward channel quality and request grade.Wherein, QoS information comprises the user gradation and/or the grade of service.In the present embodiment, for convenience of explanation, access sequence is divided for the 3*3*3=27 group inserts sequence, but in actual applications, access sequence can be divided into the N*M*L group and insert sequence.
Table 5
When UE in the response paging and/or when initiatively making a call, this UE selects an access sequence group according to QoS information, forward channel quality and current metadata cache quantity from 27 access sequence groups, and then selects an access sequence to be used for this random access probe from this group at random.Because the distribution of the QoS information of each UE, forward channel quality and current metadata cache quantity can present feature more uniformly, therefore, if UE is when responding paging and/or initiatively making a call, select to be used for the access sequence of random access probe according to QoS information, forward channel quality and current metadata cache quantity, can further avoid taking place the situation of access interference at random.
Then, enter step 320, UE sends random access probe to network side.
Then, enter step 330, the base station of network side is detected from the access sequence in the random access probe of this UE.
Then, enter step 340, the base station of network side obtains the QoS information of this calling.Specifically, the base station according to detected from the access sequence in the random access probe of this UE, the every group of corresponding relation that inserts sequence and QoS information, forward channel quality and request grade that passes through to be preserved, search and obtain the affiliated access sequence group of this access sequence, with the pairing QoS information of this access sequence group, forward channel quality and request grade as the pairing QoS information of this access sequence, forward channel quality and request grade, thereby obtain the QoS information of this calling, forward channel quality and the current metadata cache quantity of this UE of this UE.
Then, enter step 350, this UE was refused or accepted according to forward channel quality and the current metadata cache quantity of this UE of QoS information, this UE in the base station of network side in access grant message access.Because UE has passed to network side with the QoS information of calling out apace by the random access probe that sends, and the user gradation and/or the grade of service have been comprised in this QoS information, make network side can adopt more reasonably access control mechanism and mechanism of permitting the entrance, when UE access clashes at random the time, can carry out comprehensive selection according to forward channel quality, current metadata cache quantity and service priority and User Priority, thereby more reasonably distribute access-in resource.
What deserves to be mentioned is that network side can set in advance the functional switch of QoS, and the mode that the state of this functional switch is broadcasted by configuring negotiation signaling method or system message is notified to UE.If the functional switch of UE or QoS is in opening, then according to being that random access probe is selected access sequence before the QoS information, to channel quality and request grade, otherwise, forbid that according to QoS information, forward channel quality and request grade be that random access probe is selected access sequence.
The base station can be accepted or the refusal business fast by the implicit information of access sequence.
In the mobile communication system of third embodiment of the invention, comprise UE and base station.Comprise in UE: being used for basis or part is the unit and the unit that is used to send random access probe that random access probe is selected access sequence according to QoS information; In the base station, comprise and be used for detecting from the unit of the access sequence of the random access probe of subscriber equipment and be used to obtain the unit of the QoS information corresponding with detected access sequence.
