Below in conjunction with specific embodiments and the drawings technique scheme of the present invention is elaborated.Should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, the method for the mobile communication equipment logical address of present embodiment and physical address exchange may further comprise the steps:
S101: press the designing requirement of mobile communication equipment, in database, set up the mapping table of logical address and physical address, recover, store, use for system queries as backup;
This mapping table can be edited and revise by the OMC maintenance interface.
So-called logical address is the addressing mode of handling for ease of software and hardware in the device design, and logical address comprises basic station number, Sub-System Number and unit number etc.And physical address be at the user the addressing mode of visible outward appearance entity, it comprises shelf number, frame number and slot number.
During the S102:OMC startup of server,, in memory cache, set up corresponding address mapping relation according to logical address in the database and physical address map relation;
This is because the speed of access memory buffer memory is higher than the speed of direct accessing database far away, has also reduced when visiting this database the consumption to system resource simultaneously.
This step specifically comprises: the OMC server is loaded into the address mapping table of database in the memory cache, sets up the mapping relations of logical address and physical address then in memory cache.
The organizational form in memory cache about logical address and physical address should be set up rational allocation index structure by the response speed requirement of reality.Generally speaking, the equipment reporting information uses logical address, and base station equipment quantity is many, and the quantity of the reporting information of each equipment is all a lot, and reports frequency also high; Attendant's operational order uses physical address, and attendant's operation relative populations is less, and frequency of operation is low.Learn that in view of the above by logical transition be physical address, and be logical address that these two kinds of conversions are different to the requirement of response speed by physical address translations.Required to respond fast as much as possible by the conversion of logical address to physical address, physical address does not then have harsh response speed requirement to the conversion of logical address.Therefore, set up rational allocation index structure respectively according to these characteristics.
The S103:OMC server provides the address interconnect alias, comprises by the translation interface of logical address to physical address, and by the translation interface of physical address to logical address;
When address exchange interface was called, the address mapping relation in the audit memory buffer memory obtained corresponding logical address or physical address thus.
S104: during the communication apparatus reporting information, the call address translation interface is converted to physical address with logical address; During user's transmit operation order, the call address translation interface is a logical address with physical address translations.
As shown in Figure 2, the mobile communication equipment logical address of present embodiment and physical address device for interchanging 200, comprise the control module 201, map addresses tables of data module 202, map addresses cache module 203 and the address interconnect alias module 204 that connect successively, also comprise Operation and Maintenance interface module 205; Wherein:
Map addresses tables of data module 202 is used for as the logical address of permanent storage mobile communication equipment and the media of the mapping relations between the physical address.Can realize that at this stored logic address and physical address and mapping relations thereof backup recovers, and can edit easily and revise by Operation and Maintenance interface module 205, such as operations such as interpolation, change and deletion.
Map addresses cache module 203 is used for the media as the mapping relations of temporary logical address and physical address, with as the fast access mechanism to logical address and physical address map relation, is convenient to address transition inquiry and address information location.At this, set up rational memory cache mapping structure by the own characteristic of address transition, to satisfy the problem that fast processing mobile communication equipment information reports.
Address interconnect alias module 204 is used for the general-purpose interface that exchanges as logical address and physical address, reports or calls during user's transmit operation order for communication apparatus information.Because the addressing of the address of various device there are differences, for satisfying the specific (special) requirements of distinct device, the memory cache mapping structure has multiple implementation.For isolating this concrete device-dependent particularity, need the general external interface of a kind of address transition of definition.
Operation and Maintenance interface module 205, be connected with control module 201, be used for interface, under the control of control module 201, realize the content in the address mapping (enum) data table module 202 is carried out edit-modify as man-machine interaction, and to the renewal of map addresses cache module 203 corresponding contents.
As shown in Figure 3, according to logical address of the present invention and physical address memory cache structure, comprise logical address part 300 and physical address part 400.Wherein, logical address part 300 comprises:
An array object in a mobile communication Commercial deployment, is created at all base stations in base station 310 in memory cache, each base station is an element of this array object, and number just as this array index the base station.
An array object is created at all unit under each subsystem in unit 330 in memory cache, each unit is an element of this array object, and element number is just as this array index.Simultaneously, this cell array object is articulated under the corresponding subsystem element as the subobject of subsystem object.
By that analogy, further refinement of logical address can also articulate subelement or the like below the unit.The concrete degree of depth is determined according to the addressing progression of logic.
Like this, just in memory cache, set up the corresponding relation of logical address and physical address.Because logical address is to adopt the array data structured coding, Sub-System Number, unit number be directly as array index, present computer technology, and the addressing speed of array is the fastest, so this method has realized the quick conversion of logical address to physical address.
For example, the veneer of basic station number 2, Sub-System Number 1, unit number 2 is converted to physical address, then directly get physical address, promptly find shelf number, frame number and the slot number of physical address by the array index of logical address by the array index of logical address:
Shelf number: base station [2] → subsystem [1] → unit [2] → frame 1, machine frame 2, groove position 5
Because in the design of mobile communication equipment, the addressing of actual logic address may be discontinuous, for non-existent Sub-System Number, unit number, only uses occupy-place dummy argument of statement in the array, need not distribute the physical memory space, so just save memory source effectively.
For the conversion of physical address, can adopt the mode of traverse tree to logical address.Because physical address is mainly used in user's operation to the conversion of logical address, the processing speed of computer software relatively, can think user's operation be at a slow speed, low-frequency, the mode of employing traverse tree can satisfy instructions for use.
When supposing the veneer physical address translations of frame 1, machine frame 2, groove position 5 to be logical address, travel through as follows:
[1], subsystem [1], unit [1] from the base station, from top to bottom, all unit below the traversal subsystem [1], [1], unit [2] from the unit ..., up to the unit [k], relatively whether the physical address (being frame 1, machine frame 2, groove position 5) of each unit equals the physical address that will change, and the result not have the unit that mates below the subsystem [1]; After subsystem [1] search finishes, continue search subsystem [2] ..., up to subsystem [m], the result is that the inside, base station [1] not have the unit that mates.
Continue the subobject below the search base station [2], equal the physical address that will change up to the physical address of finding base station [2], subsystem [1], unit [2], then transformation result is that basic station number equals 2, Sub-System Number equals 1, unit number equals 2.
In sum, the method for use memory cache can realize the flexible conversion of logical address and physical address.Enforcement of the present invention does not need to use the physics toggle switch, does not need the information memory cell of hardware yet.In the tandem product design of mobile communication equipment, can support independent design logical address and physical address neatly, and the device interior software and hardware is handled the design concept that remains unchanged substantially, help releasing fast the communication apparatus product of different outward appearances, different capabilities, to satisfy requirements of different users.
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.
