Step 203.
It is common, CGN equipment be the port block of same user equipment allocation in same translated addresses, in order to ensure this
The availability of the application of user equipment.The port resource that translated addresses are reserved can be divided into two parts by the CGN equipment,
Used as first port resource, another part is used as second port resource, the generally money of the first port resource for one part
Source amount is more than the second port resource.The first port resource is used for CGN equipment in first time to user equipment allocation
Port resource is provided during port block；The second port resource is used for CGN equipment at second and later to user equipment allocation
Port block when port resource is provided.So, CGN equipment is user equipment in the reserved first port of same translated addresses
Resource and second port resource, can avoid first time to user equipment allocation port block rear port resource use up and cause after
The situation that continuous distribution cannot be carried out.It should be noted that the second port resource can also be divided into finer port
Resource, provides port resource in port block of the corresponding number of times to user equipment allocation in order to CGN equipment.
What deserves to be explained is, first port resource and second port resource are only not only a user equipment service, and
It is all user equipment services to need the translated addresses.
Step 203, the stock number for obtaining default port block, execution step 204.
The stock number of the default port block is the most suitable stock number for rule of thumb selecting.The default port
When the stock number of block is initialized, the stock number of the port block for pre-setting.In practical application, the stock number of default port block
For 2000.
Whether step 204, the current distribution of judgement are the first sub-distribution.If so, execution step 205, if it is not, execution step
210。
Step 205, the current distribution number of times for obtaining user equipment, execution step 206.
Resource mapping table is the information table of the user equipment that system is arranged in resource allocation process, and the content of record can be with
Source address, conversion address, conversion rear end slogan, agreement and distribution number of times including user equipment, resource mapping table such as table 1, table 2
It is shown.

| Source address | Conversion address | Conversion rear end slogan | Agreement |
Table 2
| Source address | Conversion address | Conversion rear end slogan | Agreement | Distribution number of times |
CGN equipment can obtain user from resource mapping table and currently distribute number of times, but esource impact in prior art
The corresponding list item of number of times is not distributed in table, as shown in table 1.Obtain when then CGN equipment distributes first less than current distribution number of times,
Then the current distribution number of times of CGN equipment acquiescence is 1.
Step 206, the corresponding optimized coefficients of the current distribution number of times of acquisition, execution step 207.
It is 1 that the embodiment of the present invention gives tacit consent to the corresponding optimized coefficients of the first sub-distribution.
Step 207, according to optimized coefficients and the stock number of default port block, it is determined that need to currently distribute to the user setting
The stock number of standby port block, execution step 208.
According to the optimized coefficients and the stock number of the default port block, formula is adjusted by resource and determines described working as
The stock number of the front port block that need to distribute to the user equipment, the resource adjust formula and are：
Wherein, the S0For the stock number of the default port block, the ShCurrent the user need to be distributed to for described
The stock number of the port block of equipment, the M are the optimized coefficients, and the h is the current distribution number of times of the user equipment.
Current distribution number of times h=1, the corresponding optimized coefficients of the first sub-distribution are 1, can be calculated by resource adjustment formula
CGN equipment gives stock number S of the port block of user equipment allocation for the first time1=S0/1=S0, S1For the stock number of default port block
S0。
Step 208, the stock number from first port resource according to the current port block that need to distribute to user equipment
To the user equipment allocation port block, execution step 209.
What deserves to be explained is, in the first sub-distribution, CGN equipment can not need execution step 205, step 206 and step
Rapid 207, direct execution step 208, it is default port block that acquiescence need to currently distribute to the stock number of the port block of user equipment
Stock number.
The distribution number of times recorded in step 209, renewal resource mapping table.
Increase distribution number of times list item in resource mapping table newly, resource mapping table as shown in table 2, uses current distribution number of times 1 more
The content on the new distribution number of times hurdle, obtains distribution number of times by the resource mapping table in order to resource allocation process next time.
Step 210, the current distribution number of times for obtaining user equipment, execution step 211.
CGN equipment obtains the distribution number of times k of esource impact table record, using h=k+1 as current distribution number of times.Example,
Distribution number of times such as the distribution number of times list item record of resource mapping table is 1, and due to the list item record is last distribution correspondence
Distribution number of times, then currently distribute number of times be 2.
Step 211, the corresponding optimized coefficients of the current distribution number of times of acquisition, execution step 212.
Inquired about in the front P sub-distribution per the corresponding optimized coefficients of sub-distribution according to current distribution number of times h, obtain described working as
It is front to distribute number of times corresponding optimized coefficients, wherein, current distribution number of times is h=k+1.Example, it is assumed that arrange in 3 times distributing
Optimized coefficients are corresponded to per sub-distribution all, the embodiment of the present invention assumes that the corresponding optimized coefficients of the first sub-distribution are 1, the second sub-distribution
Corresponding optimized coefficients are 4, distribute corresponding optimized coefficients for the third time for 8.If the distribution number of times obtained from resource mapping table is
1, then it is 2 currently to distribute number of times, and it is 4 to inquire the corresponding optimized coefficients of the second sub-distribution；If the distribution of esource impact table record
Number of times is 2, then it is 3 currently to distribute number of times, and inquire third time to distribute corresponding optimized coefficients is 8.
Step 212, according to optimized coefficients and the stock number of default port block, it is determined that need to currently distribute to the user setting
The stock number of standby port block, execution step 213.
According to the optimized coefficients and the stock number of the default port block, formula is adjusted by resource and determines described working as
The stock number of the front port block that need to distribute to the user equipment, the resource adjust formula and are：
Wherein, the S0For the stock number of the default port block, the ShCurrent the user need to be distributed to for described
The stock number of the port block of equipment, the M are the optimized coefficients, and the h is the current distribution number of times of the user equipment.
Example, stock number S of default port block0For 2000, current distribution number of times h is 2, and optimized coefficients M is 4,
Stock number S of the port block that formula obtains currently distributing to the user equipment is adjusted by resource2：
The stock number that then CGN equipment distributes to the port block of the user equipment is 500.
Step 213, from second port resource according to the stock number of the port block that need to currently distribute to user equipment to institute
State user equipment allocation port block, execution step 214.
Specifically, it is assumed that the stock number of the reserved port resource of translated addresses has 2000, wherein first port
Resource includes 1300 stock numbers, and second port resource includes 700 stock numbers, and user equipment needs to carry out three sub-distribution, CGN
Equipment carries out three sub-distribution port blocks to user equipment, and the stock number of the port block is followed successively by 200,50 and 25.CGN
Equipment second and the port block of third time distribution, i.e. stock number are the port block of 50 and port block that stock number is 25, are
It is allocated by the port resource of second port resource.
So, CGN equipment is that the port block of same user equipment allocation can be in same conversion address, it is to avoid
The situation that cause follow-up distribution cannot carry out is used up to the port block rear port resource of user equipment allocation in first time.
The distribution number of times recorded in step 214, renewal resource mapping table.
The distribution number of times obtained from resource mapping table is added 1 and is currently distributed number of times, with the current distribution number of times
The distribution number of times recorded in updating the resource mapping table.
It should be noted that the sequencing of resource allocation methods step provided in an embodiment of the present invention can be carried out suitably
Adjustment, step according to circumstances accordingly can also be increased and decreased, any those familiar with the art the invention discloses
Technical scope in, the method that can readily occur in change should all be included within the scope of the present invention, therefore no longer go to live in the household of one's in-laws on getting married
State.Meanwhile, the acquisition methods for distributing number of times can also have various, example, in initialization procedure, directly can reflect in resource
Distribution number of times list item is set in firing table, and the list item is recorded for 0, then the current distribution number of times for obtaining during the first sub-distribution is 0+1=
1, the acquiescence optimized coefficients of acquisition are 1.CGN equipment can also arrange special statistic unit, for recording current distribution number of times.
What deserves to be explained is, after CGN equipment is to user equipment allocation port block, CGN equipment judges whether to proceed
Distribution, CGN equipment can pass through the port that the summation of the stock number of the port block for judging to be fitted on is needed with user equipment
Stock number size is judging whether to proceed distribution.If current h sub-distribution to the stock number summation of port block be more than or wait
The stock number of the port needed in user equipment, is no longer allocated；If the stock number summation of the port block that current h sub-distribution is arrived
The stock number of the port needed less than user equipment, proceeds distribution, and wherein h represents current distribution number of times.
