Description
Technical field
The present invention relates generally to telecommunication system, relate in particular to the wired mobility in the telecommunication system.
Background technology
Under the world market, enterprise customer's mobility or client use the ability that is positioned at the station on the whole enterprise network to wish very much when still can receiving consistent telephone service.Many large-scale companies are usually along with university and branch are positioned at the dispersion that becomes all over the world.Best, it is local or specify feature and other function on the station that enterprise customer's mobility makes the client can connected reference be positioned at the client.
The current ExtensionMobility that produces such as Cisco company that is provided at of enterprise customer's mobility
TMThe voice or VoIP product based on Internet Protocol of various distributors in.Cisco product has expansion application programming interfaces or the API that allows the visit third party application, and the client need not to touch any one mobile phone just can be provided with local and the visit or the remote voip station for remote access.In order to realize reconfiguring of the long-range station, the system manager utilizes API to import user identifier or UI and personal identification number or PIN.When the client logined the accessed station and succeed checking, the accessed station utilized the local station profile information of client to reconfigure automatically.When the location in local and the accessed station involves a more than switch,, carrying out call treatment on the local switch rather than on accessed switch owing to accessed switch only plays the router effect.
But these products are confined to the VoIP station, and are not suitable for circuit switching or time division multiplexing or TDM phone.IP network generally is provided for the remarkable infrastructure of the geographical discrete part of telecommunication system.The most suitable control channel of bottom IP network, and, when
But the time spent, can provide the acceptable service quality (or QoS) or the grade of service (or GOS) for voice communication.But, when not having enough Internet resources to can be used for voice communication or one or more IP network parts to be out of order, can have a negative impact to voice communication.Though obtained huge progress aspect the voice quality in improving VoIP communication horizontal, on some frequencies, still can cause QoS or GOS rapidly and be difficult to expect that ground descends, this is unacceptable for many commerce.
For this reason, preference wire circuit exchange of many businessmans or TDM communication equipment.Although such as wired mobility in the switch of hotel level management (hoteling) or hot desk-top management (hot-desking) is known, but the wired mobility of inter-exchange enterprise customer is not useable for circuit switching or TDM communication equipment, if especially wherein the client is positioned at the his or her local station then wired mobility of all functions that the client will have near him or she.As known to, hotel level management or hot desk-top management are to allow not have the client at this board station to specify in function Anywhere in the local area network (LAN) that is subjected to public enterprise switch control.In addition, even the mobility that enables by IP, this passenger family of the remote I P phone normally associate of holding with the client who is on a journey is no longer got in touch with that IP phone.This serves problem can for the characteristic strip of the IP phone of this passenger family remote access such as abbreviated dialing, bridge joint outward appearance, dialing intercommunication etc.
By allowing user's load balance circuit-switched communications equipment between the webserver, user mobility can provide added advantage.User mobility can for example allow usually the inaccessible of the local position that local user on the website that is subjected to a server controls causes owing to any reason to be registered on the remote site, thereby " stranded " user's commercial continuity is provided.
Summary of the invention
These and other need be solved by various embodiment of the present invention and configuration.The present invention is directed to the client's mobility in concentrated or the dispersion enterprise network.
In first embodiment, a kind of method comprises the steps:
(a) on second switch/server, provide the virtual communication equipment and second electronic address;
(b) after this on second switch/server, create the visitor's application records that is associated with first client communications devices that is subjected to first switch/server controls; And
(c) response of step (b) is associated virtual communication equipment with first communication equipment, second electronic address is different from first electronic address that is associated with first communication equipment.
The virtual station of on second switch/server each has corresponding mobile user station record.For example, first mobile subscriber's station record is corresponding to second electronic address.First and second electronic addresses are normally such as the special-purpose or public number of dialing of direct Incoming or DID extension number.
With when virtual communication equipment is associated, first client continues to use first communication equipment first client, is unloaded to second switch/server but outgoing call handled.In a kind of configuration, this is by not only keeping local station record but also keep the local application records of first communication equipment to finish on first switch/server.The local station is recorded as first client and disposes first communication equipment, and local application records comprises the electronic address of virtual communication equipment separately and points to corresponding mobile user station record.With when virtual communication equipment is associated, keep local application records, first client so that the incoming call of first communication equipment is redirected to second communication equipment.

In other configuration, station 136a-n and 140a-m are the mixing of circuit switching and packet switching communication equipment.
Should be noted that, in the present invention between the switch/server and the station and/or between first and second switches/server without any need for the information transmission medium or the agreement of specific type, that is, the present invention can realize by means of the transmission medium of any required type and the combination of dissimilar transmission mediums.For example, interswitch protocol can be QSIG, SIP, H.323 wait.The control signaling can send on first and/or second network between switch/server.In a kind of configuration, first network comprises QSIG control signaling and bearer channel.
First and second switches/server 100 and each preferably software control of 104, and comprise Communication Manager such as Avaya company
TMThe controlling application program of correction form.As can be seen from Figure 1, the memory of each of first and second switches/server is included as client's station ambulant mobile agent module 150 is provided, and the load balance module 180 that provides ALB to trigger is provided the memory of first switch/server 100.The ability that mobile agent module 150 provides the client can be registered as long-range or calling party in the virtual accessed station, the described virtual accessed station is by not being different switch/server controls in the building of the actual local station of client.In case registration, the mobile agent module 150 of local switch/server are forwarded to the image of the local station of client the mobile agent module 150 of accessed or remote exchange/server.The mobile agent module 150 of accessed switch/server downloads to the virtual accessed station with image.
The normal this locality (enterprise) identity (for example, toll free number) that sends access customer is as caller information, and processing is irrelevant in this locality or on accessed switch/server with calling.When (for example on accessed switch/server, handling normal call side's information that the outgoing call and first network 108 will not accept the client, title and local station telephone number) time, send the customer call information (for example, title and accessed station telephone number) of the accessed AWOH station as option.Handle promptly (for example, 911) calling by only sending local switch/server caller information, can correctly and effectively respond with the assurance emergency response personnel, and make callback when needed.For example, if the client wants to make urgent call from accessed station 136a-n, second switch/server 104 will provide the telephone number and/or the positional information (for example, emergency location information coding or ELIN) of the AWOH station of calling out station 136a-n rather than client to public secure access point or PSAP.
To be routed to the local station 136a-n of client on the switch/server of this locality (first) to the incoming call of access customer, and, in this locality of client (first) even what keep on switch/server 100 that the client can be by his or her local station 136a-n visit is not all also to be most function.
In a kind of configuration, load balance module 180 detects to guarantee to call out to initiate to handle and is unloaded to the second switch/scheduled event of server 104 or the generation of triggering from first switch/server 100.The example of this incident comprises taking of selected function or function group.For instance, module 180 adds up to the quantity in the processing cycle that is consumed by the processing that constitutes most of exchange logics in first switch/server and determines taking of exchange logic.When taking above selected threshold value, module 180 is initiated a calling of organizing a performance the station to handle and is unloaded to second switch/server 104.Can use a plurality of threshold values.Make to each threshold increment more callings initiate to handle and be unloaded to another switch/server.
In following paragraph, the function of structure is discussed with reference to various examples.In first example, have first station 136a that is subjected to 100 controls of first switch/server and be registered as access customer by second switch/server 104 as first client of the his or her local station.
Consider this example now, the memory of first and second switches/server comprises the many data structures that realize aforementioned functional.This data structure comprises the local application records 164 of local station record 160, first station 136a of first station 136a, mobile subscriber's station record 168 of the virtual accessed station and visitor's application records 172 of the virtual accessed station.Local station record 160 is management accounts of first station, and comprise such as first customer name (or UI), first client's commonname, first station special number (for example, 5 internal numbers), the public number of first station (for example, 10 DID), the local security information of first client (for example, password such as PIN), first station type, first station buttons/keys record (for each buttons/keys provides respective markers or type and state), the COS of first station, whether first station is to allow to move, (for example, which type of calling outward appearance activates call status information, which type of calls out outward appearance in ring etc.), and the various information of pointing to the pointer (if not with the local station record cascade of first station) of local application records.Local application records 164 comprises the extension number of the virtual accessed station, the pointer (if not with the local station record cascade of first station) that points to the local station record of first station and the pointer that points to just accessed system.Mobile subscriber's station of accessed station record 168 comprises public number (for example, 10 DID), and can comprise some and general (haveing nothing to do with the user) information of the local station record same type of first station.This information can comprise that for example special number (for example, 5 internal numbers), the COS of first station type, first station buttons/keys record (for each buttons/keys provides respective markers or type and state), first station and call status information (for example, which type of call out outward appearance be activate, which type of calls out outward appearance in ring etc.).At last, visitor's application records 172 comprises that first client calls out all required information from the virtual accessed station.Therefore, it (for example comprises first client's commonname, first station special number, 5 internal numbers), the public number of first station (for example, 10 DID), virtual accessed station special number, the local security information of first client are (for example, password such as PIN), the station type of the local and accessed station, call status information (for example, which type of call out outward appearance be activate, which type of calls out outward appearance in ring etc.) and accessed station buttons/keys record.Best, record 160,164,168 or 172 is OO, but they also can be the data structures of being correlated with.
Visitor's application records 172 of the accessed station and mobile subscriber's station record 168 are independent of each other; That is to say that they are discrete record or the different physical locations that are arranged in memory, and the both can stand system's replacement.But visitor's application records 172 is pointed to really for corresponding mobile subscriber's station record of access customer use separately.
As can be seen from Figure 1, the memory of second switch/server 104 comprises a plurality of or a pond different mobile subscriber's station record 168a-j, and they each can be associated with different access person application records 172a-i.Each mobile subscriber's station record 168a-j has different special-purpose and/or public numbers, and each visitor's application records 172a-i and the 1st, the 2nd ..., the not same of n station 136a-n be associated.When by second switch/when server 104 is registered access customer, from the pond, select mobile subscriber's station record, and it is associated with client's the application records of visitor separately.When making a return journey the registration access customer by second switch/server 104, mobile subscriber's station record is turned back in the pond so that be associated with different clients.This is by related visitor's application records before the deletion fully, or only deletes the pointer that points to mobile subscriber station station record in the application records and keep application records so that be used for finishing under the incident by second switch/server 104 registrations once more same client later on again.
The operation of mobile agent module 150 is described referring now to Fig. 1-3.In each example, certain stimulation is brought out the calling of one or more station 136a-n and is initiated to transfer to second switch/server 104 from first switch/server 100.The example that stimulates comprises that the processing load on first switch/server 100 surpasses selected threshold value (or available CPU is less than selected threshold value) and first switch/server or its parts or such as the bust of another parts of gateway or link.
With reference to Fig. 2-4 first example is described below.In this example, stimulation is the excess processes load on first switch/server 100, and to be transferred station 136a-n be the packet switching station.
Forward Fig. 2 and 4 now to, load balance module 180 determines to have occurred pre-determined stimulus in square 400.Respond module 180 notice mobile agent modules 150.
In square 404, module 150 selects to transfer to one of second switch/server 104 station 136a-n that organizes a performance.This group can comprise one or more stations.In case receive notice maybe when one of the member of this group call try is initiated, module 150 each station in this group is at once transmitted termination and is cancelled registration message 224 by what first switch/server was registered the notified station.Cancel registration message and can comprise the electronic address of second switch/server 104.Be that various switch/servers can periodically exchange the processing load information under the situation of a part of public enterprise network at a plurality of switch/servers, call out the switch/server of initiating so that can select intelligently to unload.Alternately, the address of other switch/server can be stored in the station of each switch/server or its service by the preference order.
In square 408, the station of being cancelled registration sends to second switch/server 104 with registration message 228 on second (packet switching) network 110.In a kind of configuration, registration message comprises the extension number of the extension number of the station of being cancelled registration, the authorization information (for example, password) of being cancelled the station of registration and selected mobile subscriber's station record 168a-j.Extension number is by providing in cancelling registration message 224 before first switch/server 100.Then, second switch/server 104 is created visitor's application records 172a-i, and its extension number that will be cancelled the station of registration is associated with selected mobile subscriber's station record 168a-j.The knowledge of the employed and current available extension number of mobile subscriber's station record 168a-j is obtained in this configuration by first switch/server 100.In the another kind configuration, do not need this knowledge.The station of being cancelled registration will comprise the extension number of the station of being cancelled registration and the registration message 228 of customer authentication information sends to second switch/server 104.Second switch/server 104 recognizes that the extension number of the station of being cancelled registration is not the extension number of that this machine of switch/server, and can recognize that this extension number is the extension number of first switch/100 machines of server.Although this knowledge is arranged, the second switch/server 104 not refusal of registration, but select available mobile subscriber's station record 168a-j and create visitor's application records 172a-i that selected record 168a-j is associated with the extension number of the station of being cancelled registration.This configuration more caters to the need than preceding a kind of configuration, because it does not need the information of the relevant available mobile subscriber's station record of switch/server exchange in the enterprise network.In each configuration, the uniqueness of each extension number in whole enterprise network prevented the extension number conflict between switch/server.
Then, control forwards Fig. 3 to.Square 300 hypothesis second switch/servers 104 receive registration message 228 from the selected station 136a-n of first switch/server 100.
In square 304, the mobile agent module 150 of second switch/server 104 sends to mobile agent module 150 in first switch/server 100 with location update message 200.First client's of the extension number that the selected mobile subscriber's station that comprises location update message 200 writes down, the extension number of first station 136a, input the local security information and the station type (if suitable) of station record 140.Location update message 200 is actually 168a-j is write down in the registration of being sent by first client from first station 136a to mobile subscriber's station wired ambulant registration request.
In square 308, the mobile agent module 150 receiving position updating message 200 of first switch/server 100, and the local security information in the more local station record 160 and the local security information of input.If information fails to mate, if or local station record 160 indications first station 136a (for example is not suitable for wired mobility, use the COS permission), then module 150 refusal requests, and the request of will refusing is returned to the mobile agent module in second switch/server 104.If information matches, and if local station record 160 indications first station 136a be fit to wired mobility, then module 150 proceeds to step 312.If the local station writes down 160 indication users and is associated with different mobile subscriber's stations records 168, then will cancel the registration indication and pass to the accessed system of accessed record 168 before.
In square 312, the mobile agent module 150 in first switch/server 100 is created the button reflection of the local application records 164 and first station 136a.Button reflection can be any one group of data structure of the layout of the button of definition first station 136a and button.Just as expected, have two types buttons/keys, that is, button (for example, quick or abbreviated dialing) is initiated in status button (for example, the button of indicating status when being pressed, calls such as the feature that sends all-calls) and calling.The button reflection contrasts corresponding state usually and initiates buttons/keys type or mark (or first client is selected or programing function or feature) and state and indicates the buttons/keys identifier.Each programmable button/button at least the first station 136a (with non-programmable buttons/keys in some applications) has the corresponding button identifier.In other words, for each buttons/keys identifier, this reflection has the corresponding button/push-button type or mark and buttons/keys state.For example, the button reflection comprises abbreviated dialing button, intercommunication button and the bridge joint outward appearance of other extension set on first station 136a." button " and " button " is used as the alternative expression of signal excitation device in this article.
In square 316, the mobile agent module 150 in first switch/server 100 is with the position response 204 mobile agent modules 150 that send in second switch/server 100.When writing down corresponding first station and the virtual station and be same type with mobile subscriber's station, response 204 comprises first station type, button reflection, Messages-Waiting status indicator, the public number of first client, first client's special number and first client's commonname.When the station when being dissimilar, the definition of calling outward appearance that response 204 can comprise virtual station special number, the public number of the virtual station alternatively and be mapped to first station 136a of the accessed virtual station.As people recognize, often be not associated such as the virtual station of the AWOH and the X station, and can unify to be applied to all physics station types with the physics station of particular type.
In square 320, the mobile agent module 150 in second switch/server 104 receives the response of waiting for 204 and creates visitor's application records 172.The button reflection that second station buttons/keys record shines upon first station 136a by the mobile agent module 150 in second switch/server 104 by the buttons/keys layout that contrasts the virtual station generates.When the station was same type, local station record 160 and visitor's application records 172 were basic identical, but the layout difference of record.When first client activated buttons/keys on the virtual station, application records 172 rather than local station record 160 were used for determining corresponding function.
In step 324, the mobile agent module 150 in second switch/server 104 is reconfigured for the virtual station and is defined in visitor's application records 172.When the station when being dissimilar, one group of acquiescence feature only is provided on the virtual station, or alternately, the given utility function of coupling key/button.As if when the station was same type, the station was identical with first client.Between the mobility record time, first station 136a shows the mobility registration effectively, and the special number of the virtual station is provided.
Even the client is still on this local switch/server and continue to use the his or her local station, said method also can realize load balance with the lighter switch/server of another load.The load balance operation is seamless for the customer.
From mobile subscriber's station record, cancel registration and be by stopping of stimulating of first switch/server response and realize automatically, or realize by private branch exchange number and the security information that first client imports deexcitation feature access code, first station 136a.Then, the registration message 220 of cancelling that will comprise this information sends to mobile agent module 150 on second switch/server 104 from first switch/server 100.After good authentication, on first switch/server 100, remove registration, and will cancel registration message by second switch/server 104 and be forwarded to first station 136a-n.Under the sort of incident, from the memory of first and second switches/server, remove local and visitor's application records 164 and 172 respectively.Cancelling registration also can be by cancelling automatically that the registration timer expires or realizing automatically from the layout of the urgent call of first station.Cancel registration also can respond the capacity of himself handling on second switch/server 104 constraint initiation, or upgrade from the available processes capacity that first switch/server receives and to cause, or the response user on the station except that first station successful registration and automatic initiation.
Best, (for example, on the D channel under the QSIG agreement) sends message 200,204,208,212,216 and 220 outside the frequency band relevant with voice channel, to preserve bandwidth.
When mobility is registered on second station, to first client's incoming call usually by first switch/server controls, rather than by second switch/server controls.Preferably use the local switch/server controls of calling out, so that administer calls covers or be divided into the call treatment that speech message transmits on first switch/server 100.When being registered on second switch/server 104, having the incoming call of first station 136a in first the being moved property of client, mobile agent module 150 in first switch/server 100 is determined the mobility registration effectively from application records 164, and first client is registered on second switch/server.Call setup message is forwarded to the mobile agent module 150 in second switch/server to be called out so that set up.
The outgoing call that utilizes the dial on first station to carry out is handled by second switch/server 104.For example, utilize calling that abbreviated dialing on first station or intercommunication feature button send calling to be stored in the abbreviated dialing tabulation on first switch/server and the number that is transmitted to second switch/server is handled by second switch/server by utilizing.
Exchanging the station by first and second switches/server between the mobility record time upgrades.When " visit " first client between the mobility record time when first station is carried out outgoing call, mobile agent module 150 in second switch/server 104 sends to mobile agent module 150 in first switch/server 104 with outward appearance updating message 218, for calling is provided as the calling outward appearance that first station 140b selects.When between the mobility record time, when first switch/server received first client's incoming call, the mobile agent module 150 in first switch/server 100 generated and sends outward appearance updating message 216.This message 216 comprise first client's special number of first station 136a, relevant mobile subscriber's station record extension number, incoming call identifier and be the calling outward appearance of incoming call selection.This is very important, because first and second switches/server can be configured to differently selective call outward appearance.Being included in the message 216 by calling out outward appearance, is that the calling outward appearance of first switch/server 100 configurations can be used for utilizing first station 136a-n that second switch/server 104 is registered now, so that the identification incoming call.
Second switch/when server 104 was registered first station, button state updating message 208 and 212 was used for the continuous renewal of tracked button (for example, calling out outward appearance and bridge joint outward appearance) utilizing.When mobile agent module 150 received updating message, this module was upgraded the buttons/keys record of the controlled station (for example, first or second station) of main (for example, first or second) switch/server.Available updating message 208 and 212 comprises idle condition, band and state not with the alarm condition of jingle bell and in using.The stimulation of this message is the activation of the buttons/keys of first station.Therefore, when pressing feature button on first station, the mobile agent module 150 in second switch/server 104 sends to first switch/server with updating message 212, makes to activate or the required feature of deexcitation.
Therefore, first switch/server 100 is utilizing second switch/treatment state buttons/keys when server 104 is registered first station.When down state buttons/keys in first station, button state updating message 212 sends to mobile agent module 150 in first switch/server 100 by the mobile agent module 150 in second switch/server 104.In first switch/server 100, activate described feature then.Finishing this local switch characteristic processing is in order to save call.For example, when status button/button of pressing was " transmission all-calls ", how the first switch/server 100 rather than second switch/server 104 knew the route extension set.
Although be not depicted among Fig. 2, the Messages-Waiting updating message is used for the Messages-Waiting lamp state notifying second switch/server 104 with first client, and upgrades that state when it changes.
