Embodiment
The embodiment of the invention provides a kind of method, equipment and communication system of down-sending neighbor list, by changing the mode that issues of Neighboring Cell List, can save the broadcast resource of eating dishes without rice or wine relatively, improves the effective rate of utilization of interface-free resources.
Below respectively technical solution of the present invention is elaborated by specific embodiment.
Embodiment one,
Referring to Fig. 1, be the method flow diagram of a kind of down-sending neighbor list of providing of the embodiment of the invention one, specifically can comprise:
The base station obtains corresponding with terminal can adopt multiple mode, for example, can be that the base station obtains the CAMEL-Subscription-Information of terminal from network side after terminal inserts current area, and the relevant information of each adjacent home cell of current area, generate corresponding according to what obtain to information with above-mentioned terminal; Also can be to receive corresponding that network equipment (for example, Mobility Management Entity, base-station gateway etc.) sends, and be not limited thereto with above-mentioned terminal.
The base station can be diversified to the triggering mode that terminal sends the tabulation issuing message, for example, sends in the time of can being transmission when terminal request, base station timed sending, the renewal of terminal location district etc., and is not limited to above-mentioned giving an example.
As can be seen, in the present embodiment, the neighboring BS information corresponding with adjacent home cell, the base station adopts one to one that mode of unicast issues, and then can effectively reduce the length of broadcast message, saves the broadcast resource of eating dishes without rice or wine relatively; And for terminal, the base station issues the neighboring BS information of home cell Neighboring Cell List record all can think effective neighboring BS information, has improved the utilance of interface-free resources relatively.
Embodiment two,
Present embodiment is comprehensive embodiment, in this enforcement, and the neighboring BS information corresponding with common sub-district, the base station adopts the periodic broadcast mode to issue; The neighboring BS information corresponding with adjacent home cell, base station adopt the mode of clean culture one to one to issue, and referring to Fig. 2, are the method flow diagrams of a kind of down-sending neighbor list of providing of the embodiment of the invention two, specifically can comprise:
For instance, the base station can be in respective cell, and periodic broadcast lists broadcast carries common cell neighbor list information in the described tabulation broadcast, thus the purpose of the common cell neighbor list of broadcasting of property performance period.The neighboring BS information of common cell neighbor list record can include but not limited to: the unique identification of adjacent common sub-district, physical label, operating frequency, load information or the like.
Because ordinary base station is normally disposed by operator, common subdistrict position relation is definite relatively, therefore, can be by the common cell neighbor list of network side allocating cell in the base station of each sub-district, the main corresponding adjacent common sub-district of the neighboring BS information of common cell neighbor list record.Certainly, the base station of sub-district also can obtain the relevant information of the adjacent common sub-district of current area from network side, generates common cell neighbor list.
The base station can be in corresponding sub-district, periodic broadcast lists broadcast, and the terminal the sub-district in can receive the tabulation broadcast that cell base station is broadcasted, the common cell neighbor list of acquisition, and then can carry out the signal measurement of adjacent common sub-district.
The base station obtains the home cell Neighboring Cell List corresponding with terminal can adopt multiple mode, for example, can be that the base station generates the home cell Neighboring Cell List of above-mentioned terminal to the network side query-related information after terminal inserts current area; Also can be that the base station directly receives the home cell Neighboring Cell List corresponding with above-mentioned terminal that network equipment (for example, Mobility Management Entity, base-station gateway etc.) sends, and be not limited thereto.Base station and/or network side generate the home cell Neighboring Cell List can according to but be not limited to following information: the state information of Home eNodeB and/or load information and/or unique identification or physical label change information and/or user allow access information, with ordinary base station absolute/relative position information etc.
Preferably, because different user is not quite similar usually to the access authority of each home cell, after the user inserts current area, the base station can be inquired about this user's MM Context to network side, perhaps CAMEL-Subscription-Information of this user etc., and then can determine in each adjacent home cell of this user's current area which home cell allows this user to insert, which home cell does not allow this user to insert.According to the result who determines, the base station can generate the home cell Neighboring Cell List to should the user, the adjacent home cell that corresponding this user of current permission of the neighboring BS information of above-mentioned home cell Neighboring Cell List record inserts.
For instance, usually each home cell is to there being a closed user group group id (CSG ID, Closed Subscriber Group ID), after user's (terminal) A inserts current area, the base station can be to Mobility Management Entity (MME, Mobility Management Entity) MM Context of inquiring user A, record the closed subscriber group (CSG of user A in the above-mentioned MM Context, Closed Subscriber Group) tabulation, the home cell of each CSG ID of record all allows user A to insert in the CSG tabulation.CSG tabulation according to user A, the base station just can be judged in each adjacent home cell, which allows user A to insert, which does not allow user A to insert, according to the result who judges, the base station can respective user A, generates the home cell Neighboring Cell List, the adjacent home cell that the corresponding current permission of the neighboring BS information user A of above-mentioned home cell Neighboring Cell List record inserts.
The data format of home cell Neighboring Cell List can be identical with common cell neighbor list, and the neighboring BS information of its record can include but not limited to: the unique identification of adjacent home cell, physical label, operating frequency, load information or the like.
For instance, the home cell Neighboring Cell List of user A can be as shown in table 1, but be not limited to this:
Table 1
| The adjacent area unique identification | The adjacent area physical label | The consular district operating frequency | The adjacent area load information |
| ??A1 | ??A2 | ??F1 | ??N1 |
| ??B1 | ??B2 | ??F2 | ??N2 |
| ??C1 | ??C2 | ??F3 | ??N3 |
| ??...... | ??...... | ??...... | ...... |
Similar to common cell neighbor list, each bar record of home cell Neighboring Cell List, the neighboring BS information of a corresponding adjacent home cell.For example, in the adjacent home cell of current area, the home cell that current permission user A inserts has 5, and then the home cell Neighboring Cell List of user A corresponds respectively to 5 home cells that current permission user A inserts to 5 records should be arranged.
For instance, because different terminals is not quite similar usually to the access authority of each home cell, after terminal A inserts current area, the base station can send the tabulation issuing message to terminal A, carry the home cell Neighboring Cell List in this tabulation issuing message, the adjacent home cell that the corresponding current permission terminal A of the neighboring BS information of above-mentioned home cell Neighboring Cell List record inserts.
Preferably, the base station can also be provided with version identifier for the home cell Neighboring Cell List, and carries this version identifier in issuing message, with version identifier the real-time effectiveness of home cell Neighboring Cell List is carried out distinctive mark.Above-mentioned version identifier can be the set of number numbering that recycles in order, also can be that certain or certain characteristic value with the home cell Neighboring Cell List of this version is as input, the random identification that the process computing obtains, or the data label that generates according to incremental manner (for example, 002....), and be not limited thereto 001.The home cell Neighboring Cell List not only can be carried in the base station in the tabulation issuing message that terminal sends, can also carry its corresponding version identifier.Version identifier with the home cell Neighboring Cell List is that the digital coding that generates according to incremental manner is an example below, describes.
Preferably, terminal can be stored the home cell Neighboring Cell List of the base station transmission that receives, and corresponding version identifier, and can send confirmation of receipt message to the base station, and it has received successfully the home cell Neighboring Cell List informing base station.Can carry user ID in the above-mentioned confirmation of receipt message, and the sample sign of the home cell Neighboring Cell List that successfully receives of terminal etc.
Further, after terminal receives down-sending neighbor list message, can check the relation between the version identifier of the version identifier that carries in the message and current preservation, if meet rule, then carry out the renewal of Neighboring Cell List, and preserve new version identifier; Otherwise, can not carry out the renewal of Neighboring Cell List and version identifier.For example, the home cell Neighboring Cell List version identifier of definition is the label that increases progressively, i.e. version of the every generation in base station, and version identifier increases by 1.Terminal is when receiving home cell down-sending neighbor list message, the version identifier in the message that inspection is received and the version identifier of current preservation compare, if the version identifier that receives is not more than the version identifier of preservation, terminal is not carried out the renewal of Neighboring Cell List and version identifier, otherwise upgrades.
Further, the base station can be after sending the tabulation issuing message to terminal, start timer, be provided with and (for example receive the stand-by period, 2 seconds), if in the time that is provided with, do not receive the confirmation of receipt message that terminal sends, illustrate that terminal may take defeat, then can be to the above-mentioned tabulation issuing message of terminal re-sends; If receive the confirmation of receipt message that terminal sends in the time that is provided with, can judge further then whether the version identifier that above-mentioned confirmation of receipt message carries is identical to the version identifier of the home cell Neighboring Cell List of the up-to-date transmission of this terminal with the base station, if it is different, it is wrong to think that this terminal receives, still can be to the above-mentioned tabulation issuing message of this terminal re-sends.
As can be seen, the base station has realized that by man-to-man mode the clean culture of home cell Neighboring Cell List issues, and then has reduced the data volume of broadcast message greatly.
Because Home eNodeB mostly is the individual or group has, its operating state may often change, and for example, opens, closes, dormancy, load variations or the like, causes home cell to allow the access situation often to change.
For instance, but the operating state of the adjacent home cell of the base station timing detection base station of sub-district, variation has taken place if find the operating state of some or all of adjacent home cell base station, cause counterpart terminal A, variation has taken place in the permission access situation of some or all of adjacent home cell, then can upgrade the home cell Neighboring Cell List of the terminal A of previous generation, and the relative set version identifier, the adjacent home cell that the same corresponding current permission terminal A of the neighboring BS information of the home cell Neighboring Cell List record after terminal A upgrades inserts.Similarly, also can when variation has taken place the permission access situation of some or all of adjacent home cell, regenerate the home cell Neighboring Cell List of terminal A, and the home cell Neighboring Cell List that generates is sent to the base station by network side finding counterpart terminal A.
For instance, the indication information that list update message is carried can be the home cell Neighboring Cell List of the terminal A of renewal, and above-mentioned list update message can also carry its corresponding version identifier.Terminal A is after the list update message that receives the base station transmission, whether version identifier that can further more previously stored home cell Neighboring Cell List is identical with the version identifier that above-mentioned list update message is carried, if identical, then do not upgrade previously stored home cell Neighboring Cell List; If different, then can utilize the home cell Neighboring Cell List that receives to replace previously stored home cell Neighboring Cell List, and can send confirmation of receipt message to the base station, can carry user ID in the confirmation of receipt message, and the sample sign that receives etc.
Preferably, the indication information that the list update message that the base station sends is carried also can be to upgrade the operation indication, and the different piece of the home cell Neighboring Cell List of the home cell Neighboring Cell List of the terminal A that upgrades in the base station and the current storage of terminal A.To upgrade the operation indication can be retouching operation indication and/or deletion action indication and/or increase operation indication etc., and terminal A makes amendment to the record of the home cell Neighboring Cell List of storage according to above-mentioned renewal operation indication and/or deletes and/or operation such as increase.
For example, the home cell Neighboring Cell List of the terminal A of base station and the current storage of terminal A is a table 1, its sample is designated 001, the base station is that resting state etc. has been closed or entered in the home cell load base station full or this home cell of A1 by the adjacent area unique identification that detects record in the table of discovery 1 of back, variation has taken place in the permission access situation of this home cell, and terminal A is current can not to have inserted this home cell.In view of the foregoing, base station updating form 1 is the record deletion of A1 with adjacent area unique identification in the table 1, and the home cell Neighboring Cell List of the terminal A after the renewal can be as shown in table 2, and the base station is that the version identifier that table 2 is provided with can be 002, but is not limited to this:
Table 2
| The adjacent area unique identification | The adjacent area physical label | The consular district operating frequency | The adjacent area load information |
| ??A1 | ??A2 | ??F1 | ??N1 |
| ??C1 | ??C2 | ??F3 | ??N3 |
| ??...... | ??...... | ??...... | ??...... |
Preferably, the indication information that the list update message that the base station sends to terminal A is carried can comprise: deletion action instruction, adjacent area unique identification A1, and version identifier 002.
For instance, terminal A compares the version identifier of reception and the version identifier of current preservation after receiving above-mentioned list update message, finds 002 greater than 001, meets the version identifier rule.Delete according to indication information then that the adjacent area unique identification is the corresponding neighboring BS information record of A1 in the home cell Neighboring Cell List of its storage, and the version identifier of updated stored is 002.Simultaneously, can send confirmation of receipt message, can carry user ID in the confirmation of receipt message to the base station, and information such as the sample that receives sign 002.
Again for example, the home cell Neighboring Cell List of the terminal A of base station and terminal A storage is a table 2, its sample is designated 002, the base station finds have a new adjacent home cell base station to be activated by detecting the back, its sub-district unique identification is D1, physical label is that D2, operating frequency are that F4, load information are N4, and this home cell permission terminal A access, and variation has taken place the permission access situation of the adjacent home cell of current area.In view of the foregoing, base station updating form 2, adding the adjacent area unique identification in table 2 is the neighboring BS information record of D1, and the home cell Neighboring Cell List of the terminal A after the renewal can be as shown in table 3, and the base station is that the version identifier that table 3 is provided with can be 003, but is not limited to this:
Table 3
| The adjacent area unique identification | The adjacent area physical label | The consular district operating frequency | The adjacent area load information |
| ??A1 | ??A2 | ??F1 | ??N1 |
| ??C1 | ??C2 | ??F3 | ??N3 |
| ??D1 | ??D2 | ??F4 | ??N4 |
| The adjacent area unique identification | The adjacent area physical label | The consular district operating frequency | The adjacent area load information |
| ??...... | ??...... | ??...... | ??...... |
Preferably, the indication information that the list update message that the base station sends to terminal A is carried can comprise: increase operational order, adjacent area unique identification D1, adjacent area physical label D2, adjacent area operating frequency F4, adjacent area load information N4, and version identifier 003.
For instance, terminal A compares the version identifier that receives and the version identifier of current preservation after receiving list update message, finds 003 greater than 002, meets the version identifier rule.In the home cell Neighboring Cell List of its storage, increase the corresponding neighboring BS information record that the adjacent area unique identification is D1 according to indication information then, and the version identifier that renewal is preserved is 003.Simultaneously send confirmation of receipt message, can carry user ID in the confirmation of receipt message to the base station, and information such as the sample that receives sign 003.
Again for example, the home cell Neighboring Cell List of the terminal A of base station and terminal A storage is a table 3, its sample is designated 003, the base station finds that by detecting the back sub-district unique identification is that the operating frequency of the home cell of A1 has changed to F5, and the sub-district unique identification is that variation has taken place the operating state of the home cell of A1.In view of the foregoing, base station updating form 3, the adjacent area unique identification is the neighboring BS information record of A1 in the modification table 3, the adjacent area operating frequency that it is corresponding is revised as F4 by F1, the home cell Neighboring Cell List of user A after the renewal can be as shown in table 4, the base station is that the version identifier that table 4 is provided with can be 004, but is not limited to this:
Table 4
| The adjacent area unique identification | The adjacent area physical label | The consular district operating frequency | The adjacent area load information |
| ??A1 | ??A2 | ??F4 | ??N1 |
| ??C1 | ??C2 | ??F3 | ??N3 |
| ??D1 | ??D2 | ??F4 | ??N4 |
| ??...... | ??...... | ??...... | ??...... |
Preferably, the indication information that the list update message that the base station sends to terminal A is carried can comprise: retouching operation instruction, adjacent area unique identification D1, adjacent area operating frequency F4, and version identifier 004.
For instance, terminal A is after receiving list update message, the version identifier that receives and the version identifier of current preservation are compared, find 004 greater than 003, meet the version identifier rule, then revise corresponding neighboring BS information record in the home cell Neighboring Cell List of its storage, and the version identifier of updated stored is 004 according to indication information.Simultaneously, can send confirmation of receipt message, can carry user ID in the confirmation of receipt message to the base station, and information such as the sample that receives sign 004.
For instance, above-mentioned list update message can adopt following message format, but is not limited to this:
| Type of message | Version identifier | Upgrade number | Update content 1 | Update content 2 | ...... |
Terminal can be resolved this message after receiving the list update message of above-mentioned form, carry out the corresponding operation of upgrading, and upgrades the home cell Neighboring Cell List of its storage.
Further, the base station can be after sending list update message to terminal, start timer, be provided with and (for example receive the stand-by period, 2 seconds), if in the time that is provided with, do not receive the confirmation of receipt message that terminal sends, illustrate that terminal may take defeat, then can be to the above-mentioned list update message of terminal re-sends; If receive the confirmation of receipt message that terminal sends in the time that is provided with, can judge further that then version identifier that above-mentioned confirmation of receipt message carries is whether identical with the version identifier that carries in the list update message that the base station sends, if different, then still can be to the above-mentioned list update message of this terminal re-sends.
Being understandable that the base station can initiatively send the tabulation issuing message to terminal, and/or list update message, also can be to send the request back in terminal to the base station to send.For example, terminal sends list request message to the base station, and the base station sends the tabulation issuing message to terminal after the list request message that receives the terminal transmission, carry corresponding home cell Neighboring Cell List in this tabulation issuing message, and to corresponding version identifier.Terminal can send confirmation of receipt message to the base station after receiving the tabulation issuing message, confirm to receive successfully.
Be understandable that step 201 and step 202 there is no inevitable ordinal relation to 205, step 201 can be to carry out at any time.
Need to prove that the embodiment of the invention is described, the base station that is used to issue Neighboring Cell List can be an ordinary base station, can be Home eNodeB also, and be not limited thereto.
As can be seen, in the present embodiment, with the corresponding Neighboring Cell List in adjacent common sub-district, the base station adopts that the mode of periodic broadcast issues, the Neighboring Cell List corresponding with adjacent home cell, the base station is adopted one to one, and mode of unicast issues, can effectively reduce the length of broadcast message, save the broadcast resource of eating dishes without rice or wine relatively; And for terminal, the neighboring BS information of the home cell Neighboring Cell List record that the base station issues all can be thought effective neighboring BS information, has improved the utilance of interface-free resources relatively.
Further, when the permission access situation of the adjacent home cell that allows terminal to insert changes, the base station can send to terminal and only carry the list update message of upgrading indication information, with respect to send whole Neighboring Cell List to terminal for, the data volume of upgrading indication information is littler, can further save interface-free resources; And various message can send flexibly according to opportunity, and implementation is varied.
