Description

The implementation method of the whole network calling in a kind of mobile communication system

Technical field

The present invention relates to moving communicating field, particularly relate to the implementation method of the whole network calling in a kind of mobile radio system.

Background technology

In mobile radio system, mobility is its outstanding feature, and the mobile region that relates to is changed, and whole system is formed by the combination of network of multiple region.In order to support that whole user moves between different region networks, roaming is generally adopted to realize mobile calls in current mobile communications technology, in this approach, user has a fixing ownership region network, the service area network using current place is then needed when user moves to the region of other network coverages, but realize user normally to use under service area network and comprise registration, calling etc., service area network must with ownership the region network interconnection, and link is reliable, need to initiate new registration message to the region network of this user attaching under user moves to service area network, once two link between networks faults, user cannot succeed in registration under service area network, user is caused to use network.Therefore current loaming method requires that internetwork link is reliable, in order to reach this requirement, and current employing wired backbone transmission, and require that two server net equipment are fixing immovable.

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

Summary of the invention

Unreliable in order to solve each region link between networks in mobile communication, but the problem that can converse under user roams into any network's coverage area will be ensured, the invention provides the implementation method of a kind of the whole network calling, 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,

After system user makes a call under current separate mesh, if current SWITCH judges called as home subscriber, then initiating broadcast & call all separate mesh, then thinking access success when receiving the response of any one separate mesh, remove the calling of other separate mesh; The end of calling when the calling of all separate mesh is all failed.

Preferably, for external system user, it can be configured under the switch docked with external system out to external system, under other all switches, be configured to home subscriber.It can also be configured under the switch docked with external system out to external system, under other all switch, be configured to the out switch to described docking.

Instant invention overcomes in existing mobile radio system and adopt roaming scenarios to realize user mobility must to rely on the reliable defect of link between grid, when between grid, still can realize the business such as user's registration, call when link instability.

Embodiment

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

Embodiment one

In the present embodiment, have multiple independently network 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 that the user under each network can roam mutually, and can user under access success current network or other network at any one network.

Based on above-mentioned requirements, each separate mesh of the present embodiment comprises the communication equipment of complete set, 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 the switch configuration under all separate mesh to be home subscriber, because only have home subscriber just can trigger the whole network calling.

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

Step 1: originating exchanger receives the call request of user, carries out number analysis, judges called as home subscriber;

Step 2: originating exchanger judges called as triggering the whole network call flow after home subscriber: on the one hand office call flow process traditionally carries called number inquiry attaching position register under this switch, sends INVITE on the other hand to other all interconnected switches simultaneously;

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

Step 3: this switch directly calls called subscriber according to the UID returned, and does not exist, the call failure under this switch, wait for the response of other switches if returned.

Step 4: other switches receive after INVITE by traditional office call flow processing, carry called number inquiry attaching position register equally, after attaching position register returns called UID, switch calls out called subscriber according to UID, if paging success, transmission 180 or 200OK message are to originating exchanger, and call failure sound is then play by originating exchanger;

Step 8: originating exchanger first 180 of receiving that response success under this switch or other switches return or 200OK message are then thought and discharged the calling of other switches by access success; Originating exchanger just thinks this call failure after receiving the call failure response of all switches (comprising self), terminates this calling.

The flow process of above-mentioned the whole network calling originating exchanger realizes as shown in Figure 2, and the flow process of the whole network calling receiving end switch realizes as shown in Figure 3.The visible control to the whole network calling is all at originating exchanger forever, no matter finally called whether under originating exchanger, due to wireless terminal user can only boarding under a base station, and under a base station also can only belong to a switch, therefore final access success is believable, and for catv terminal user, because it does not exist mobility substantially, be therefore equally also accurately believable.

Embodiment two

If user dials the user under non-native system, as PSTN user, then first need under the switch docked with PSTN network, to be configured to striking out to PSTN, then this docking switch initiates to be undertaken by traditional outbound call flow process the calling of PSTN.Tradition outbound call flow process is as shown in Figure 4: user dials outgoing numbers, switch number analysis result is called is outbound user, HLR is not then needed to inquire about, direct query routing administration module routing iinformation, switch selects corresponding protocol type to be routed to peer switches according to the result of route analysis.

For other all switches, simply PSTN user still can be configured to home subscriber.Now other docking switches initiate will trigger the whole network call flow to the calling of PSTN, and final calling can in the switch striking out of docking to PSTN.

Or for other all switches, also PSTN user can be configured to the out switch to docking with PSTN network.Now other switches initiate not walk the whole network call flow to the calling of PSTN, and outbound call flow process is traditionally carried out, more out to PSTN by docking switch.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
