102, ENUM/DNS determines the priority of P-CSCF equipment by processing weight.
What deserves to be explained is, ENUM/DNS is after receiving the processing weight of P-CSCF equipment, according to the priority of disposal right recanalization P-CSCF equipment.In a kind of optional implementation of the present embodiment, the method for priority adjustment is that the processing weighted value of P-CSCF equipment is larger, and the priority of P-CSCF equipment is higher, and then a plurality of P-CSCF equipment is sorted, and generates host name list.
103, ENUM/DNS generates the host name list of P-CSCF equipment according to the priority of P-CSCF equipment, makes SBC carry out traffic assignments according to host name list.
What deserves to be explained is, SBC carries out traffic assignments according to host name list, refer to that SBC, for the UE (User Equipment, subscriber equipment) by its access carries out P-CSCF devices allocation, is the P-CSCF equipment access IMS network that this UE distributes thereby make UE by SBC.
Description in conjunction with above-mentioned 103, by ENUM/DNS, receive the processing weight that P-CSCF equipment reports, and according to the disposal right of P-CSCF equipment, re-generate the host name list of P-CSCF equipment, when subscriber equipment is initiated registration request to IMS network, SBC is to the address of ENUM/DNS request P-CSCF equipment, ENUM/DNS sends to SBC by host name list, for SBC, to being linked into the business of this SBC, distributes.The host name that comprises all P-CSCF equipment under ENUM/DNS in host name list can be also the IP address of all P-CSCF equipment under an ENUM/DNS.
In this step, for the particular content comprising in host name list, provide following two kinds of processing modes:
The first processing mode, while comprising the host name of P-CSCF equipment in host name list,
At ENUM/DNS, to SBC, send after host name list, SBC carries out A inquiry to ENUM/DNS, and A inquiry is for obtaining the inquiry mode of host ip according to host name.SBC asks the IP address of the P-CSCF equipment that this host name list medium priority is the highest to ENUM/DNS, then by the business being accessed by this SBC by IP address assignment to corresponding P-CSCF equipment.
The second processing mode, while comprising the IP address of P-CSCF equipment in host name list,
At ENUM/DNS, to SBC, send after host name list, SBC is according to the highest IP address of host name list medium priority, the IP address that priority is the highest in the present embodiment can be in this host name list, to arrange the most forward IP address, and then traffic assignments is arrived to the P-CSCF equipment corresponding with this IP address.
For the embodiment of SBC distribution service, in subsequent step 301 and 302, there are specific descriptions, at this, do not repeat.
The embodiment of the present invention provides a kind of implementation method of network long-distance disaster, load between can the many complete equipments of balanced P-CSCF, by obtaining the processing weight of P-CSCF equipment, and dynamically adjust P-CSCF priority facility according to this processing weight, and according to the host name list of this priority generation P-CSCF equipment, thereby make the user who accesses by SBC can be assigned to the P-CSCF equipment that priority is high, significantly reduce the load difference distance of P-CSCF equipment room, thereby realized the load balancing of many cover P-CSCF equipment rooms.
In another kind of embodiment provided by the invention, described the specific implementation of determining the priority of P-CSCF equipment by processing weight, as shown in Figure 2, having comprised:
201, ENUM/DNS, according to processing weight order from big to small, sorts to locating P-CSCF equipment corresponding to weight.
In above-mentioned 101, to the description of processing weight and processing the computing formula of weight, for example, there is the processing weight of two P-CSCF equipment to be respectively 30 and 50, two equipment order in host name list sorts according to order from big to small, processes weight and be 50 P-CSCF equipment more forward than the position of processing P-CSCF equipment that weight is 30 in host name list.
202, ENUM/DNS determines the priority of P-CSCF equipment according to putting in order of P-CSCF equipment.
Wherein, the priority of P-CSCF equipment becomes positive correlation with processing weight, and the processing weight of P-CSCF equipment is larger, and priority is high.
Another embodiment of the present invention provides a kind of implementation method of network long-distance disaster, in conjunction with method flow as shown in Figure 1, after step 103 generates the host name list of P-CSCF equipment, proposed to upgrade the method for the host name list of P-CSCF equipment, as shown in Figure 3, comprising:
301, when the priority of P-CSCF equipment changes, according to the priority update host name list after P-CSCF equipment variations.
Another embodiment of the present invention provides a kind of implementation method of network long-distance disaster, as shown in Figure 4, also comprises:
401, ENUM/DNS receives the domain name to be checked that SBC sends.
Wherein, domain name to be checked is that SBC is the domain name that roamer distributes.SBC be domain name that roamer distributes and SBC for the domain name of local user's distribution different.
It should be noted that, when having user's equipment access to SBC, SBC is the different P-CSCF domain name of user equipment allocation for access according to user type.For example, the user UE 2 in Beijing user UE 1 of this area and ownership Guangdong, is accessed and is initiated registration request to IMS network by SBC.Request-Line (request line) field in the registration message of SBC extraction UE 1, UE 2, from this field, obtain each UE home network domain name and the contrast of local domain names, determine that user UE 1 is for Beijing local user, UE 2 is roamer, and specifically constant current journey really will illustrate in following step a, for Beijing user UE 1 distributes the domain name of P-CSCF, being pcscf.bj.cn, is pcscf.roam.bj.cn for Guangdong user UE 2 distributes the domain name of P-CSCF.Beijing user is this area, and suppose that there are 2 P-CSCF equipment of equipment this area, be respectively P-CSCF 1 equipment and P-CSCF 2 equipment, when SBC is linked in the responsible region of P-CSCF 1 equipment by local user so, the domain name that local user is assigned with is pcscf1.bj.cn, when SBC is linked in the responsible region of P-CSCF 2 equipment by local user, the domain name that local user is assigned with is pcscf2.bj.cn, and for belonging to other regional roamers, SBC is the domain name of its distributing uniform, the domain name that is roamer is all pcscf.roam.bj.cn.
402, when domain name to be checked be SBC be roamer distribute domain name time, to SBC, send host name list.
Wherein, the P-CSCF list of devices that host name list corresponding to domain name to be checked will access for roamer, SBC, according to the priority of P-CSCF equipment in host name list, selects the P-CSCF equipment that priority is the highest to receive roamer's business.And for local user, can select SBC with the local user access P-CSCF equipment in the same area to receive local user traffic.
Description in conjunction with above-mentioned 301, the host name list generating dynamically updates, the host name list sending to SBC can also be the host name list after upgrading, that is: when domain name to be checked be SBC be roamer distribute domain name time, to SBC, send the host name list after upgrading.
In the present embodiment, the form of the host name list that ENUM/DNS sends to SBC comprises but does not limit by form as shown in table 1 below and represents, in this table 1, the first row comprises " domain name " successively, " host name of P-CSCF ", " priority " three class parameters, and take domain name as pcscf.roam.cn be example, under this domain name pcscf.roam.cn, there are two P-CSCF equipment, their host name is respectively pcscf1.ims.cn, pcscf2.ims.cn, and the priority of these two equipment is followed successively by P-CSCF1, P-CSCF2, the processing weight that ENUM/DNS reports according to P-CSCF equipment dynamically updates priority.
