Description
Technical field
The present invention relates to the distributed cellular wireless telecommunication system, the connection control method of particularly a kind of privately owned subnet division methods and private cell.
Background technology
The distributed cellular wireless telecommunication system is mainly by terminal, base station and core net (CN) are formed (referring to Fig. 1), between base station and core net, also may there be base station controller or distributed network controller (referring to Fig. 2), be used for management of base station and converge the connection of base station to core net.The network that base station and network controller are formed is called wireless access network (RAN), is responsible for the Access Layer affairs, such as the management of Radio Resource.Each base station or network controller can be connected with one or more than one core net.Core net is responsible for the Non-Access Stratum affairs, such as mobile management etc.Terminal be meant can with the equipment of network communication, such as mobile phone or notebook computer etc.The user of terminal generally need and wireless communication networks operator signatory, to obtain the right of the business that the use wireless communication networks provides.The user of terminal can be referred to as the user.
For higher service rate being provided to the user and reducing the required expense of high rate services of using, also can remedy simultaneously the deficiency of existing distributed cellular wireless telecommunication system to subscriber household or office's covering, the base station can be repacked into the WiMAX access device that is easy to carry and installs in wireless communication networks operator, offers the user and is placed on family or office's use.The base station that offers public's use with the unified plan of wireless communication networks operator is referred to as public base station herein, and the wireless access sub-district that disposes on this base station is referred to as common cell; User installation is referred to as privately owned (or family expenses) base station in the base station of own family or office, the wireless access sub-district that disposes on this base station is referred to as privately owned (or family expenses) sub-district.
Be different from common cell and service be provided for the contracted user of all operators, the often only open small number of users of giving owner's appointment of privately owned (or family expenses) base station of private cell.For preventing the access of non-designated user, private cell has been introduced access control function, do not allow the user that inserts if the user who inserts in the request of certain privately owned (or family expenses) sub-district is not the owner of this privately owned (or family expenses) base station, then can refuse provides service for this user.
Though above-mentioned access control function can realize preventing unexpected user's access, shortcoming is that terminal must could confirm whether certain user can insert in certain sub-district behind the access procedure through attempting.This access attempts process must need to carry out between terminal and wireless access network or the core net a series of interacting message.If arranged private cell in certain focus geographic area (zone that has a large amount of mobile subscribers), the process that then unexpected user attempts inserting will cause a large amount of signaling message flow quantities, and the waste interface-free resources increases system loading.
A kind of method of avoiding above-mentioned defective is the numbered list of the private cell that oneself is authorized to insert at the terminal record.Terminal reads the numbering of this private cell earlier when selecting the sub-district, have only when the numbering of this sub-district list memory the time just attempt inserting, otherwise need not attempt inserting, therefore avoid unnecessary cut-and-try process, help reducing system loading.
But use the method for cell number also to have shortcoming.Owner such as privately owned (or family expenses) base station is a tissue, and this tissue has a plurality of privately owned (or family expenses) base station, and is provided with a plurality of private cells, and these sub-districts may need to be provided with identical list of authorized users.Because the numbering of all sub-districts all has nothing in common with each other, if use the method that is authorized to cell number at the terminal record, then the member of this tissue may have to write down a lot of cell number in the terminal of oneself.
Summary of the invention
The technical problem to be solved in the present invention provides the privately owned subnet of a kind of distributed cellular wireless telecommunication system and divides and corresponding private cell connection control method, solve and waste interface-free resources, the shortcoming that increases system loading or too much occupy terminal resource when existing private cell inserts.
In order to solve the problems of the technologies described above, the invention provides the privately owned subnet division methods of a kind of distributed cellular wireless telecommunication system, comprise,
Private cell is divided into privately owned subnet;

In described private cell, during the transmitting system broadcast, fill in privately owned subnet title cell, the privately owned subnet under the indication private cell.
Further, said method also can have following characteristics, and described privately owned subnet name is called character string forms.
Further, said method also can have following characteristics, and described private cell belongs to one or more privately owned subnets, correspondingly comprises one or more privately owned subnet titles in the system broadcast message of described private cell.
A kind of distributed cellular wireless telecommunication system private cell connection control method increases privately owned subnet title in terminal, and the privately owned subnet that indicating terminal is authorized to when described terminal is carried out the sub-district access, comprises following steps:
(a) terminal reading system broadcast if comprise privately owned subnet title in the system broadcast message, changes step (b) over to;
(b) terminal compares the privately owned subnet title of this locality preservation and the privately owned subnet title in the system broadcast message, if having identical privately owned subnet title, execution in step (c);
(c) terminal attempts inserting this sub-district.
Further, said method also can have following characteristics, in the described step (a), if do not comprise privately owned subnet title in the system broadcast message, then changes step (c) over to.
Further, said method also can have following characteristics, in the described step (b), and if there is no identical privately owned subnet title, then the terminal insertion authority of this sub-district not selects other sub-districts to attempt inserting.
Further, said method also can have following characteristics, in the described step (c), if terminal attempts inserting this sub-district failure, then selects other sub-districts to attempt inserting.
Further, said method also can have following characteristics, and the privately owned subnet that described terminal is authorized to is one or more, and one or more privately owned subnet titles are correspondingly preserved in described terminal this locality.
Further, said method also can have following characteristics, and described privately owned subnet name is called character string forms.
Further, said method also can have following characteristics, in system side, private cell is divided into privately owned subnet, for described privately owned subnet is specified privately owned subnet title, in the system broadcast message of private cell, increase cell and represent privately owned subnet title, the privately owned subnet under the indication private cell.
Use method of the present invention, by dividing privately owned subnet, terminal only writes down the title of privately owned subnet and does not need to write down the numbering of each private cell, reduced the list that terminal need write down, in addition, privately owned subnet title generally has certain implication, uses the network title to be easier to domestic consumer's management than the cell ID that uses numeral number, and a plurality of sub-districts are merged into a subnet, be convenient to office type site management access control authority.
Description of drawings
Fig. 1 is the direct-connected distributed cellular wireless telecommunication system of a base station and core net structure chart;
Fig. 2 distributed cellular wireless telecommunication system structure chart that to be the base station link to each other by controller with core net;
Fig. 3 is that terminal was selected the sub-district decision flow diagram after the present invention increased privately owned subnet title.
Embodiment
For the distributed cellular wireless telecommunication system, the WAP (wireless access point) that service is provided is the sub-district.In order to guarantee that terminal can use the Radio Resource of sub-district, comprise parameters such as frequency, common signal channel, the sub-district can be in system broadcast message relevant information such as broadcast radio parameter repeatedly.Terminal receives the setting that also just can obtain the sub-district wireless parameter after the system broadcast message, makes a call according to these settings then.
The present invention allows the owner of privately owned (or family expenses) base station that one's own private cell is arranged to a privately owned subnet by following method, and the terminal of authorized user only need write down the title of privately owned subnet and not need to write down the numbering of each sub-district again like this:
Be set as follows in system side:
1) private cell is divided into privately owned subnet, it is privately owned subnet title that the owner of privately owned (or family expenses) base station sets a network title for the privately owned subnet that will be provided with.
2) change system broadcast message increases cell and represents privately owned subnet title.This cell is broadcasted in all sub-districts of this privately owned subnet as other cells in the system broadcast message.
In system message, increase the method for privately owned subnet name information, the same with other wireless parameters, in system message, use (or a plurality of) cell to represent that privately owned subnet title gets final product.Position and the implication of this cell in system message needs clearly regulation, so that terminal can correct understanding.
3) for each sub-district in the privately owned subnet, no matter whether continuous on the region, wireless access network equipment all needs to fill in privately owned subnet title cell when the transmitting system broadcast, indicate privately owned subnet under this sub-district, promptly will carry the information of the affiliated privately owned subnet of private cell in the system broadcast message.
Wherein,, also can allow a private cell belong to a plurality of privately owned subnets simultaneously, promptly in the broadcasting of this sub-district, can have a plurality of privately owned subnet titles simultaneously in order to realize different authority management and group.
Be set as follows in end side:
4) software of change terminal recognition system broadcasts, make its can the reading system broadcast in the cell of the privately owned subnet title of expression.
5) the change terminal is selected the mechanism of sub-district, it can be provided be authorized to privately owned subnet name list, and select the sub-district to attempt inserting according to privately owned subnet title.
The user needs the title (having a plurality of) of the privately owned subnet that record oneself is authorized in the terminal equipment of oneself in advance.For the ease of memory, the title of privately owned subnet can adopt character string forms.Privately owned subnet title generally has certain implication, uses the network title to be easier to domestic consumer's management than the cell ID that uses numeral number.
After increasing privately owned subnet title in the system broadcast message, whether terminal judges can select this sub-district to attempt method such as the Fig. 3 that inserts, specific as follows:
Step 301: terminal is elder generation's reading system broadcast when selecting the sub-district, to obtain the relevant wireless parameter configuration of this sub-district.
Step 302: whether have privately owned subnet title in the terminal judges system broadcast message.If there is no privately owned subnet title forwards step 304 to; Otherwise, change step 303 over to;
Step 303: if there is the title of privately owned subnet, then terminal is with the name list that is authorized to subnet of this name-matches self storage.If being authorized in the subnet name list of terminal record is identical without any the title with the privately owned subnet of Cell Broadcast CB, then it fails to match, promptly thinks the not insertion authority of this sub-district of terminal, change step 306 over to, otherwise the success of subnet name-matches changes step 304 over to.
304: terminal attempts inserting this sub-district.
305: whether judgement inserts successful, if attempt the access procedure failure, as because of reasons such as the subnet name repeat, then changes step 306; Otherwise, change step 307 over to.
306: terminal can't insert in this sub-district, selects other sub-districts.
307: the cell selecting process finishes, and continues subsequent process.
