Further, after the above-mentioned GGSN network element that breaks down recovered operate as normal, the GGSN network element that takies the IP address resource of the above-mentioned GGSN network element that breaks down was given back the IP address resource piece that takies the GGSN network element that recovers operate as normal.Particularly, when giving back the IP address resource piece that takies, the GGSN network element that takies the IP address resource of the GGSN network element that breaks down can be according to the current operating position of IP address resource piece that takies, substep is given back the IP address resource piece that takies the GGSN network element that recovers operate as normal piecemeal, online user and network is impacted avoiding.
The foregoing description can realize that the IP address resource is shared between each GGSN network element in GGSN pond, and need not increase extras, can not change network topology structure, can not increase extra activation processing delay.
Below with GPRS/ universal mobile telecommunications system (Universal Mobile Telecommunications System; Hereinafter to be referred as: UMTS) network is an example, and the method that the address pool that the embodiment of the invention is provided is heavily distributed describes.
Fig. 3 is the networking schematic diagram of an embodiment of GPRS/UMTS network of the present invention, and as shown in Figure 3, GGSN-1 network element, GGSN-2 network element and GGSN-3 network element are formed the GGSN pond, and is interconnected by IP backbone the whole network with Home Network SGSN-1 and SGSN-2.The IP address of distributing to the GGSN-1 network element in the present embodiment is IP1, and the IP address of distributing to the GGSN-2 network element is IP2, and the IP address of distributing to the GGSN-3 network element is IP3; The IP address resource that the GGSN pond is had is designated as IP_total, then IP_total=IP1+IP2+IP3.Further IP1, IP2 and IP3 can be divided into IP address resource piece as shown in Figure 4 respectively: (IP1.1, IP1.2), (IP2.1, IP2.2), (IP3.1, IP3.2).Fig. 4 divides the schematic diagram of an embodiment for IP address resource piece of the present invention.
In order to realize when a GGSN network element breaks down in the above-mentioned GGSN pond, the IP address resource that the GGSN network element that this breaks down is had can be used by the GGSN network element of operate as normal in this GGSN pond, IP address resource piece among Fig. 4 can be rearranged according to mode shown in the dotted line among Fig. 5, form one-level resource backup pond.Fig. 5 divides the schematic diagram of an embodiment for IP address resource one-level resource backup of the present invention pond.
When certain GGSN network element breaks down in the GGSN pond, the GGSN network element of operate as normal will be seized the IP address resource piece of the GGSN network element correspondence that breaks down in this GGSN pond in above-mentioned one-level resource backup pond.For example: when the GGSN-1 network element breaks down in the GGSN pond, the GGSN-2 network element will be seized the IP1.1 address resource piece of GGSN-1 network element correspondence, and the GGSN-3 network element will be seized the IP1.2 address resource piece of GGSN-1 network element correspondence.After the GGSN-1 network element recovered operate as normal, the GGSN-2 network element was given back the IP1.1 address resource piece of seizing the GGSN-1 network element that recovers operate as normal; The GGSN-3 network element is given back the IP1.2 address resource piece of seizing the GGSN-2 network element that recovers operate as normal.
The mode that above-mentioned IP address resource piece is divided can be easy to expand at least two GGSN network elements of adaptation and form the GGSN ponds and the situation of one-level resource backup division at least.
In general, the number of the GGSN network element that comprises in the GGSN pond is n, when maximum fault rank (being backup level) also is n, IP address resource piece is divided and the method for generation resource backup matrix can be as shown in Figure 6, and Fig. 6 is the flow chart of an embodiment of resource backup matrix generating method of the present invention.
Step 601, NMS is with the IP address resource IP of each GGSN network element in the GGSN pond i(i=1 ..., n-1 n) is divided into (n-1) piece IP address resource piece, is labeled as IP I.j(i=1 ..., n-1, n; J=1 ..., n-1).
Step 602, definition resource backup matrix A=(a Pq) N * n, definition rotating vector t i=[IP I.1..., IP I.j..., IP I.n-1] T(i=1 ..., n-1, n).
As implied above, rotating vector t iIP address resource piece by each GGSN network element is formed, wherein, and each the element a among the resource backup matrix A PqItself be and t iThe vector that possesses identical dimensional.
Step 603 is with t iAssignment is to the element in resource backup matrix first row, even a of resource backup matrix A respectively I1=t i(i=1 ..., n-1, n); Make all the other element a the element in first row among the resource backup matrix A Pq(p=1 ..., n-1, n; Q=2 ..., n-1 temporarily is empty n).
Step 604, capable and first row carry out the dimensionality reduction operation according to i with the resource after assignment backup matrix, i dimensionality reduction matrix of the resource backup matrix after the acquisition assignment, promptly remove capable and first element that is listed as of i of resource backup matrix A, make the resource backup matrix after the assignment become (n-1) * (n-1) dimension matrix, above-mentioned i dimensionality reduction matrix can be designated as A (i1)
Wherein, i=1 ..., n-1, n.
Step 605, after the rotating vector that the IP address resource piece of i GGSN network element in the above-mentioned GGSN pond is formed carried out p circulation rotation, assignment was given the element that k is listed as in above-mentioned i the dimensionality reduction matrix.
Wherein, p=i+k-2, k=1 ..., n-1.
That is to say, to rotating vector t iAfter carrying out (i+k-2) circulation rotation, obtain vectorial t I (i+k-2), then with vectorial t I (i+k-2)In the element assignment give A (i1)Element in the k row.
Afterwards, NMS circulation execution in step 605 and step 606 are until all elements assignment in the resource backup matrix A being finished the matrix of gained resource backup at this moment A=(a Pq) N * nThe number that is the GGSN network element that comprises in the GGSN pond is n, the resource backup matrix when maximum fault rank also is n.
