Abstract

The invention provides an implementation method of whole-network calling in a mobile communication system. The mobile communication system comprises a plurality of independent networks, each independent network is provided with a home location register, a switch and a base station, all switches are interconnected according to session initiation protocol (SIP), all users of the system are configured to be home subscribers under all the switches, and data bases of all home location registers keep the user data synchronous. After a user of the system initiates a calling under the current independent network, when the user is judged to be a home subscriber by the switch, broadcasting is initiated to call all the independent networks. When a response of any independent network is received, the calling is regarded to be successful, and callings of other independent networks are removed. When the callings of all the independent networks fail, the calling is over. The implementation method of the whole-network calling in the mobile communication system has the advantages of overcoming the defects that the existing roaming solutions only can achieve mobility of users when links between systematic networks are reliable, and still being capable of achieving services of registration conversation and the like, of the users under the condition of instability of the links between the systematic networks.

Description

The implementation method that in a kind of mobile communication system, the whole network is called out

Technical field

The present invention relates to moving communicating field, relate in particular to the implementation method that in a kind of mobile radio system, the whole network is called out.

Background technology

In mobile radio system, mobility is its outstanding feature, mobile relates to the region change, and whole system to be combination of network by a plurality of regions form.in order to support whole user to move between different region networks, generally adopt roaming to realize mobile calls in current mobile communication technology, in this method, the user has a fixing ownership region network, when moving to other network coverages regional, the user needs to use the service area network at current place, but realizing that the user can normally use under the service area network comprises registration, call out etc., the service area network must with the ownership region network interconnection, and link is reliable, when moving to, the user needs to initiate new registration message under the service area network to the region network of this user attaching, in case two link between networks faults user can't succeed in registration under the service area network, cause the user can't use network.Therefore it is reliable that current loaming method requires internetwork link, in order to reach this requirement, and current employing wired backbone transmission, and to require two server net equipment be fixing immovable.

If yet the link between network unstable (such as each region link between networks in a certain private network mobile communication is unreliable) in system, and server net equipment needs mobilely, so also adopts the scheme of roaming to be difficult to meet the demands.

Summary of the invention

Unreliable in order to solve in mobile communication each region link between networks, but to guarantee that the user roams into the problem that can converse under any network's coverage area, the invention provides the implementation method that a kind of the whole network is called out, the method comprises:

Each separate mesh of system is equipped with attaching position register, switch and base station, and all switch SIP are interconnected, and all users of system are configured to home subscriber under all switches, and the database of all attaching position registers keeps user data synchronization,

System user after making a call under current separate mesh, if current switch judgement called be home subscriber, initiate all separate mesh of broadcast ﹠ call, think access success when receiving the replying of any one separate mesh, the calling of removing other separate mesh; When the calling of all separate mesh end of calling during failure all.

Preferably, for the external system user, can with its with switch that external system docks under be configured to outly to external system, be configured to home subscriber under other all switches.Can also with its with switch that external system docks under be configured to outly to external system, be configured to out switch to described docking under other all switches.

The present invention has overcome in existing mobile radio system and to adopt the roaming scheme to realize that user mobility must rely on the reliable defective of link between grid, still can realize the business such as the user registers, conversation in the unsettled situation of link between grid.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.

Embodiment one

In the present embodiment, a plurality of independently networks are arranged under certain mobile communication system, each separate network is all removable, and is transmitted as insecure wireless transmission between network, and all switches adopt SIP trunk interconnected.Now require the user under each network to roam mutually, and any one network can the access success current network or other network under the user.

Based on above-mentioned requirements, each separate mesh of the present embodiment comprises a complete communication equipment of cover, comprise base station equipment, switch device and attaching position register etc., mobile communication system realizes the whole network call business by the cooperation of switch and home location server.Wherein home location server is responsible for user data synchronization, guarantees that system user has identical user data (comprising Subscriber Number, user UID etc.) at all attaching position registers; Calling procedure is mainly taken as the leading factor with switch, and all users of system need to the switch configuration under all separate mesh be home subscriber, calls out because only have home subscriber just can trigger the whole network.

When system user made a call under current separate mesh, its whole network call flow was specific as follows:

Step 1: the switch of making a start is received user's call request, carries out number analysis, judges that called is home subscriber;

Step 2: the switch of making a start judgement is called for triggering the whole network call flow after home subscriber: carry called number inquiry attaching position register according to traditional office call flow process on the one hand under this switch, all interconnected switches send INVITE to other simultaneously on the other hand;

Tradition office call flow process is as shown in Figure 1: the user dials the local exchange number, the switch number analysis result is called is home subscriber, go attaching position register inquiry called user information, if attaching position register can find corresponding user return to called subscriber UID (the direct queried access location register of switch if attaching position register returns to response timeout), switch is according to the lane place at the UID direct paging user place of returning.

Step 3: this switch is according to the UID that returns direct calling called subscriber, do not exist call failure under this switch if return, and waits for the response of other switches.

Step 4: other switches are received after INVITE by traditional office call flow processing, carry equally called number inquiry attaching position register, after attaching position register returns to called UID, switch is called out the called subscriber according to UID, if paging success would send 180 or 200OK message to the switch of making a start, the call failure sound is play by the switch of making a start;

Step 8: the switch of making a start receive that response success under this switch or other switches return first 180 or 200OK message think and discharge the calling of other switches by access success; The switch of making a start is received and is just thought after the call failure response of all switches (comprising self) and finish this calling by this call failure.

The flow process that above-mentioned the whole network is called out the switch of making a start realizes as shown in Figure 2, and the flow process that the whole network is called out the receiving end switch realizes as shown in Figure 3.The control of as seen the whole network being called out is all at the switch of making a start forever, no matter final called whether under the switch of making a start, because wireless terminal user can only be boarded under a base station, and a base station also can only belong under a switch, therefore final access success is believable, and for the catv terminal user, because there is not mobility basically in it, be therefore equally also accurately believable.

Embodiment two

If the user dials the user under non-native system, as PSTN user, at first need to switch that the PSTN network docks under it is configured to out to PSTN, should the initiation of docking switch be undertaken by traditional outbound call flow process by the calling of PSTN.Tradition outbound call flow process is as shown in Figure 4: the user dials out number, the switch number analysis result is called is the outbound user, do not need the HLR inquiry, direct query routing administration module routing iinformation, switch selects corresponding protocol type to be routed to end switch according to the result of route analysis.

For other all switches, can simply PSTN user still be configured to home subscriber.This moment, other docking switches initiated will trigger the whole network call flow to the calling of PSTN, and final the calling can be out to PSTN at the switch of docking.

Perhaps for other all switches, also PSTN user can be configured to out switch to docking with the PSTN network.This moment, other switches initiated the whole network call flow is not walked in the calling of PSTN, carries out according to traditional outbound call flow process, more out to PSTN by the docking switch.

The above is only preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
