Referring again to Fig. 1, below the user management model of exemplary embodiment of the present is described more specifically.
1. user profile taxon
User profile is exactly and user-dependent all information summations.The user profile taxon is responsible for collecting user profile, the analytical information characteristic, and roughly be classified into two types:
Main information: main and part that relative fixed is constant in the user profile is the information summation that each user must have.The memory headroom that it takies can be referred to as Master Information Block.
Supplementary: other parts in the user profile except that main information are the information summations that can dynamically increase and delete according to user type or other needs.The memory headroom that it takies can be referred to as side information block.
2. user profile resolving cell
The user profile resolving cell requires and system index according to the EMS memory occupation of determining, user profile rationally is decomposed into main information and supplementary.Wherein the number of distributable Master Information Block is exactly the supported maximum number of user of system, thereby guarantees to reach the requirement of system index.
3. user profile memory management unit
The user profile memory management unit is responsible for the storage/distribution/management such as release of main information and supplementary.Need to determine suitable storage administration mode as the case may be, guarantee that promptly system satisfies system index, satisfy the EMS memory occupation requirement again.
Fig. 3 shows the flow chart according to the concrete implementation step of the user management model of the embodiment of the invention.
With reference to Fig. 3, a method that realizes the user management model is provided, this method comprises:
1. rationally determining EMS memory occupation and system index, mainly is the maximum number of user index.
Influence determines that the factor of system index is a lot, such as the current index of industry, and the location of self system and propaganda etc.
Influence determines that the factor of EMS memory occupation is also a lot, and such as the total memory size of system, other unit take with population size planning etc.
System should gather various factors, determines rational system index, mainly is the maximum number of user index.Simultaneously also should determine rational Memory Distribution Map, guarantee the rational EMS memory occupation of user management subsystem.
2. collect, sort out user profile:
The user profile taxon is collected user profile, and the analytical information characteristic is sorted out.
3. decomposition user profile
The user profile resolving cell rationally decomposes according to EMS memory occupation situation and system index.
1) dissimilar user profile decomposition methods
Main information can be preserved the minimum user type information of function in all types.The function that is comprised in this user type can be thought user's basic function.
Can preserve the intersection of other functions among the other types user or certain subclass of intersection etc. in the supplementary.These functions can be thought user's enhancement function.
2) decomposition method of increased functionality type user profile
Main information can be preserved user's basic function.
Supplementary can be preserved certain subclass of enhancement function intersection or intersection etc.
As can be seen, two kinds of user profile is olations that provide above can be unified to decompose according to concept of function, promptly are decomposed into basic function information and enhancement function information, and the benefit of doing like this is extensibility and the reusability that strengthens design.
4. rationally store and managing user information:
The user profile memory management unit selects to adopt static storage management and two kinds of implementations of dynamic memory management according to concrete needs.
1) static storage management, referring to Fig. 4, wherein, N is a maximum number of user, and M is for strengthening number of users:
System is according to predetermined maximum number of user and enhancement function number of users, rationally reserved storage space.The storage size summation of reserving is at least Master Information Block * maximum number of user+side information block * enhancement function number of users.Two parts space both can be reserved separately, also can share formula and reserve.
When new user inserts,, this user stores this user's main information for distributing Master Information Block from reserved storage space.When this user's main information does not need to preserve, discharge.
In the time of need be when the user asks new function or user type to change,, this user stores this user's supplementary for distributing side information block from reserved storage space for the user storage supplementary.When this user's supplementary does not need to preserve, discharge.
2) dynamic memory management:
System does not need independent reserved storage space.
When new user inserts, for this user dynamically applies for the Master Information Block memory space from global memory.When this user's main information does not need to preserve, discharge.
In the time of need be when the user asks new function or user type to change for the user storage supplementary, for this user from global memory dynamically the application side information block store this user's supplementary.When this user's supplementary does not need to preserve, discharge.
As can be seen, the advantage of static storage way to manage is that user management subsystem can rationally be set maximum user and enhancement function number of users according to given EMS memory occupation requirement, reaches the system index requirement.The advantage of dynamic memory management mode is that user management subsystem is not monopolized or headspace, can with the abundant common storage space in other unit, shortcoming is to guarantee to satisfy system index fully, has also increased simultaneously the expense that Dram distributes and discharges.
Consider base station foreground system for efficient and stable requirement, the static storage mode is more suitable for each user management subsystem of base station foreground relatively.
Below describe according to exemplary embodiment of the present invention.
Suppose that a base station foreground system must support the user of two types of A and B, and the maximum number of user index is 40 general-purpose families, the model and the implementation method of its user management subsystem are as follows:
1. determine EMS memory occupation and system index
System index is: support A and category-B type user maximum to add up to 400,000 simultaneously.
EMS memory occupation requires: be no more than 100M.
2. analyze and decomposition user profile
About 200 bytes of each category-A type user profile.
Each category-B type user profile is approximately 1000 bytes.
As can be seen, according to the storage policy of static block, given request memory can be preserved 400,000 category-A type user information blocks after the simple computation; But in order to support category-B type user simultaneously, each user information block can only be got category-B type user profile block size, obviously is to preserve 400,000 users.
In fact, category-B type user has increased many new functional characteristics on category-A type user's basis.Therefore can carry out Function Decomposition according to the decomposition model that provides above:
Main information: mainly preserve all information of category-A type user, and suitably increase some category-B type users' flag information.
Supplementary: the intersection of preserving the peculiar function information of category-B type user.
Through decomposing, main information unit piece is approximately 200 bytes, about 800 bytes of supplementary cell block.
Simple computation can be known, under given EMS memory occupation requires, can distribute 400,000 main information (approximately taking 80M), thereby reach the index of system, promptly supports 40 general-purpose families.
3. rationally store and the managing user information piece:
Consider the stable and efficient of foreground system, adopt the static storage mode.Consider the EMS memory occupation requirement, adopt main information and supplementary independently to reserve the mode of memory headroom separately.
Given memory headroom: 100M
Given maximum number of user index: 400,000
Actual memory takies situation:
Main information EMS memory occupation 80M supports 40 general-purpose families.
Supplementary EMS memory occupation 20M, maximum is supported 2500 category-B type users simultaneously.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
