Description

The implementation method of PSTN is accessed in a kind of IP scheduling system when the deployment of terminal strange land
Technical field
The present invention relates to the implementation method of access PSTN more particularly to a kind of IP when a kind of deployment of terminal strange land to dispatch system The implementation method that PSTN is accessed when middle terminal strange land is disposed, belongs to field of communication technology.
Background technique
In existing IP scheduling system, scheduling cluster server can pass through voice gateways and PSTN (Public Switched Telephone Network, i.e. public switched telephone network) it connects, networking structure is as shown in Figure 1.Work as called number When being interpreted as public network phone, scheduling cluster server Center_A routes to call business according to routing configuration R-CA-GA Then gateway Gateway_A goes to PSTN and carries out called subscriber's addressing.
Under such system group network mode, when dispatch terminal is in the presence of mostly disposing in IP scheduling system, non-scheduled cluster The terminal in server location must then dial local area code when calling local public network phone, and practical talk business is length It converses on way.
As shown in Fig. 2, scheduling cluster server Center_A is with being deployed in A (Beijing), terminal UE _ B_1 is with being deployed in B (Guangzhou).Terminal in all scheduling systems is all registered on Pekinese's central server.When terminal UE _ B_1 needs to call this The public network phone on ground: 9-66668888 (it is assumed that the public network telephone service identification code being arranged in IP scheduling system be 9, below with For this) when, it is necessary to dial local area code, it may be assumed that otherwise 9-020-66668888 can regard Beijing local call: 9- by default 010-66668888.Thus there are problems that user is inconvenient to use and generates additional toll message expense.Terminal UE _ B_1 exists Problems are equally existed when dialing special service number.
To solve the above-mentioned problems, the mode of strange land group network is realized, while also as a kind of raising system reliability Mechanism can usually be disposed using the bicentric mode in strange land, and two centers adhere to two places and mutual backup separately, each by Gateway is connect with local PSTN.As shown in figure 3, its realization mechanism can simply understand are as follows: two places user belongs to two respectively Domain, terminal user is registered in its home domain under normal circumstances, when one of center is broken down, the user of ownership place Another center that is registered to can be switched, opposite end center can receive user to roam, and can normally provide service.When double centers all When normal, terminal UE _ A_1 is registered on scheduling cluster server Center_A, service channel Center_A；Terminal UE _ B_1 It is registered on scheduling cluster server Center_B, service channel Center_B.When terminal UE _ A_1 calls public network phone 9- When 66668888, called by gateway Gateway_A to PSTN network, the called subscriber finally called is UE_X (010- 66668888)；When terminal UE _ B_1 calling public network phone 9-66668888, called by gateway Gateway_B to PSTN network, The called subscriber finally called is UE_Y (020-66668888).
But when dispatching cluster server Center_A exception, terminal UE _ A_1 switching is registered to scheduling cluster service On device Center_B, service channel is also changed to Center_B therewith, when terminal UE _ A_1 needs to call public network phone, Zhi Nengtong Gateway Gateway_B calling is crossed to PSTN network, user does not perceive registrar and switches at this time, it is likely that causes to exhale Cry failure or calling error.
