Description

The device, network and the method that are used for cordless telecommunication
The present invention relates to the private telecommunication network technical field, this network comprises the device of handling cordless terminal, is connected to and the mobile service server that is connected (mobilitg server) from cordless terminal in the cordless telecommunication net such as processing.These devices are also handled the business that allows cordless terminal obtainable service in special use does not have netting.Which specifically, the present invention relates to cordless terminal is registered as the device that belongs to a processing cordless terminal and how find such cordless terminal to belong to the technology of the device of processing cordless terminal.
In comprising the private network world of private branch exchange, each private branch exchange also comprises cordless terminal and is rendered as the ordinary terminal of ordinary telephone set, and processing of configuration belongs to that this switch is visited in the home subscriber database (home database) of the cordless terminal of this switch and registration but the calling party data transfer rate (visitor data base) that belongs to the cordless terminal of other switches in each switch usually.
Also there are some mobile service servers to be configured to handle some cordless terminals now and can use function.In WO96/21330 and WO96/21329, disclosed mobile service server by the state-of-the-art design.Be rendered as the expansion or the additional node form of private branch exchange by the mobile service server of this two files design, handle and the communicating by letter of the cordless terminal that is connected to these private branch exchanges by radio switchboard.These mobile service servers comprise the device of the function of handling the cordless terminal that belongs to server, but also comprise the device of the function of the terminal of handling a mobile service server of visit.
According to prior art, each node of handling cordless terminal all is the home node (home node) of the cordless terminal of some in the private telecommunication network, and wherein each such terminal each has a number in certain number sequence and indicates in other words.Therefore, each node just has number sequence separately, handles certain geographic area.For example can be the wireless system of company's configuration in the city, can there be two factories that are in the both sides, city respectively in this company, and for example one is in the north side, and another is in the southern side.North side factory is handled by a first node, and southern side factory is handled by a Section Point.These two nodes interconnect, and making can the exchanging telephone traffic between these two nodes.The cordless terminal that belongs to first node for example can have sign or the number with number 1 beginning, and the cordless terminal that belongs to Section Point can have sign or number with number 2 beginnings.
The user of a cordless terminal temporarily when mobile, any problem can not appear between node.Network design becomes to make each node all have a home subscriber database and a calling party database, thereby can connect the calling to the user, as long as the user is in this private network.This is to realize by the home subscriber database of visit home node.Therefore the home subscriber database contains points out that terminal is positioned at the indication of which calling party database, and which node what just pointed out also that terminal connected is, if this node is not a home node.So, call out and be connected to home node, receive an access node from home node again.
Yet, when moving to another node, some problems will appear on user's chronicity ground (for example 6 months).
For example, Mr. Andersson who supposes to have a number or be masked as 10005 cordless terminal will forward southern side factory 6 months to from north side factory, and he wishes to keep his number.
Here, problem is that all are connected to or will will connect by home node all the time from Andersson.Therefore, home node must with the access node mass communication, this just has been added to extra load on the telecommunication line between home node and the access node.Telecommunication line is in order to deal with the essential increase capacity of this extra load, thereby the total cost of network is increased.
On the other hand, suppose Andersson with he number 10005 chronicity forward southern side factory to.Because number is relevant with different nodes, so Andersson just must change his number into a number in his number sequence of new home node.Andersson can obtain a new number 20010.Because number changes, Andersson must return his cordless terminal so that reprogramming also must notify all can call out his people his new digit.
As a result, just we can say, if in by the network of prior art design the chronicity status be equipped with change and keep number and still change number and all some problems can occur.
WO95/15664 has disclosed a kind of radio-type system in local loop.In this system, when registering in the ownership Access Network of a subscriber unit at it, just the ownership access code with this unit sends to this subscriber unit, is stored in the there.When this cell moving to one visit Access Network was registered there, this subscriber unit just sent to the visit Access Network with its ownership access code, so that it is contacted with the ownership Access Network.

How the table 46 that Fig. 2 A shows in the Section Point is only realized with two row.Be designated as first of sign and show the sign of terminals all in the whole network, and the secondary series that is designated as node is shown these terminals and belonged to the indication of mobile service server in other words of which node respectively.The sign 10001,10002 and 10003 of three terminals of the node 1 that belongs among Fig. 1 or the first mobile service server has been shown among Fig. 2 A, belong to the sign 20001,20002 and 20003 of three terminals of node 2, and the sign 30001,30002 and 30003 that belongs to three terminals of node 3.In fact this table shows the sign of much more terminal that belongs to each node respectively, but three terminals of each node only are shown for brevity.Here the sign that a details will mentioning is the cordless terminal shown in Fig. 2 A all is that the employing known architectures is that node distributes.That is to say, all cordless terminals that belong to node 1 respectively have one to be included in sign or number in the number series of 10000 beginnings, all cordless terminals that belong to node 2 respectively have one to be included in number or sign in the number series of 20000 beginnings, and all cordless terminals that belong to node 3 respectively have one to be included in the number in the number series of 30000 beginnings.The mode of this assignment number is the part of current techniques, but the present invention is not limited to this mode of node assignment end mark that is, this will further specify after a while.Therefore, can use the number of any kind for the terminal that belongs to a concrete node.
Fig. 2 B shows the home subscriber database of the 3rd node among Fig. 3, and it comprises four row.First row are designated as sign, wherein show the sign of each terminal that belongs to this node.Secondary series is designated as access node, points out to step on the positional information which node is terminal in HDB just visiting or can find corresponding terminal in which VDB.The 3rd row are designated as summary of traffic, point out the type of the available service of each terminal.Last row are designated as KI, contain to be used for the cordless terminal of wanting access network or request service (for example upgrading the position) is carried out the code word of authentication.The HDB of Fig. 2 B includes only three terminal information: terminal 30001 access nodes 3 (in fact represent its at all not visit, but in the zone of the actual home node that is in it), the first summary of traffic PROFILE 1 and KI KEY 30001 had; Terminal 30002 access nodes 2 have the second summary of traffic PROFILE2 and KI KEY 30002; Terminal 30003 access nodes 1 have the first summary of traffic PROFILE1 and KI KEY30003.Summary of traffic points out that a terminal can obtain the service of which type, and some fronts are wherein mentioned.Can maybe mustn't talk through the overseas telephone and arrange different summary of traffic by only allowing some terminal to beat local call.Many different business are arranged, and wherein a handful of only mentioned in the front, therefore can set up a large amount of different summary of traffic.In fact HDB certainly comprises much more terminal information.The HDB of other two nodes have with node 3 in the identical structure of this HDB.
Fig. 2 C shows the VDB of node 1, and it comprises all terminal information in the geographic area that is in the first mobile service server among Fig. 1.VDB comprises that is shown four row that are denoted as sign, home node, RE number and the KI of connecing.These row point out to be in the sign of the cordless terminal in the geographic area of the first mobile service server, belong to which mobile service server or home node separately, separately with all with radio switchboard that the first mobile service server is connected in which radio switchboard wireless link, and be used for the terminal of wanting access network is carried out the KI of each terminal of authentication.For brevity, this VDB includes only three terminal information, but in fact it certainly comprises much more terminal information.Therefore, this table comprises the following information of the terminal of access node 1: terminal 10001 belongs to node 1 and (represents that in fact it is not in visit, and in the zone of the actual home node that is in it), be connected with RE* (* here represent it with Fig. 1 in a RE18 beyond a RE be connected, because have only a RE to be connected among Fig. 1 with node 12), have KI KEY 10001; Terminal 20002 belongs to node 2, is connected with RE*, has KI KEY20002; And terminal 30003 belongs to node 3, is connected with a RE18 among Fig. 1, has KI KEY30003.The VDB of other two nodes have with node 1 in the identical structure of this VDB.
Structure by the private network of first preferred embodiment design has been described above, will have described its working condition below in detail.
At first with the signaling between the summary description different entities, i.e. how co-ordination of different entities in the private network connects to set up traffic.
Signaling between interior two the mobile service servers of network is carried out signaling schemes and the employing DSS1 from the mobile service server to public network (digital subscriber signaling system) according to QSIG (isdn signaling on the Q reference point).Signaling between CT30, base station 24 and the RE18 is well-known in this technical field, can be referring to standard ETS 300 175.Signaling between RE and the mobile service server is carried out according to the signaling based on the signaling schemes DSS1 that communicates by letter between PBX and the public network.This signaling schemes DSS1 has done modification, so that consider the characteristics of mobile service.Therefore, new signaling schemes has the measure of handling different mobile service items in the DECT net, as the measure of handling authentications according to standard ETS300 769, handle measure of upgrading positions and the measure of handling incoming calls and exhalation according to standard ETS 300 695 according to standard ETS 300692.
Basically there are two kinds of situations will use table 46 of the present invention, during promptly at the position reproducting periods with in the incoming call of setting up the cordless terminal in the network.
Illustrate that below in conjunction with Fig. 1,2A, 2B, 2C and 3 an initial terminal is set to belong to the situation of network of the present invention, Fig. 3 wherein shows the flow chart that a terminal is added the method for private network of the present invention.
When for example resembling the cordless terminal of the terminal 30 among Fig. 1, at first provide authentication information and specify a sign or number, in this example for indicating 30003 (steps 86) for this terminal for one of network adding of the present invention.Then this sign or number are logined the HDB of the node that this terminal will belong to.HDB also receives and packs the authentication information corresponding authentication key of terminal and the summary of traffic (step 88) of terminal into.For terminal 30, this means that node 3 elects home node as, have the node that the terminal 3 of sign 30003 is belonged in other words, so the HDB54 of this node receives summary of traffic PRDFILEI and KI KEY30003.Summary of traffic points out to allow terminal can obtain which service.Yet, the access node row are not set earlier in HDB, the setting of these row will just be carried out when terminal is connected in network.After this, set up the table 46 in the node 2, the home node (step 90) of registered terminal.For the terminal 30 with number 30003, so home node is set to node 3.Access node will just be set when terminal is connected in network.When a cordless terminal moved around in no netting or roams, it sought to contact with radio switchboard.If it touches its unacquainted radio switchboard, it just asks the position to be upgraded.Wherein whether stepped on this cordless terminal so the mobile service server is checked in its VDB,, just in VDB, detected KI if this terminal is registered there.If this terminal is not registration there also, for example cordless terminal just activates or moves to from the zone of a mobile service server situation in the zone of another mobile service server recently in system, and the mobile service server is just attempted to find out this terminal and belonged to which node.This is former to be to contact with an interval related mobile service server of the number with this sign place by analysis mark to finish again.To illustrate under this situation it is how do i below.As long as a cordless terminal moves in the geographic area of the mobile service server of the node that it is registered in the VDB of a mobile service server, after carrying out authentication with the KI that is stored in this terminal in the VDB, the position just obtains upgrading automatically.
To contain which mobile service server be that one of the situation of table of the information of home node is that the position is carried out when upgrading in the geographic area that promptly moves to another mobile service server at a cordless terminal because from a node motion to another node from the geographic area of a mobile service server thereby consult.Below in conjunction with Fig. 1,2A, 2B, 2C this situation is described, Fig. 4 wherein shows by the present invention and carries out the position method for updating.
Suppose that at first the first cordless terminal CT 30 has sign 30003, belong to node 3 (so this node is also referred to as home node), and also be there at first, just be in the 3rd geographic area 6.So the tables 46 in the node 2 can comprise terminal that an expression has sign or a number 30003 and belong to the indication of node 3.So the HDB 54 of node 3 can comprise summary of traffic and KI and it and visit the information of which node (can be changed to access node 3 originally).So the VDB 52 of node 3 also can comprise the indication that expression terminal and certain RE that is connected with the 3rd mobile service server 16 connect.So other HDB and VDB can not contain the information of this terminal 30.
Hypothesis terminal 30 moves to first geographic area 2 of node 1 now, and therefore this node is also referred to as access node, more specifically, moves to a zone that is covered by first base station 24 that is connected with a RE18.CT30 may not be familiar with this base station and RE, therefore will send a position updating request (step 60) that comprises sign 30003 to a RE18.So the first mobile service server 12 is just checked VDB36, so that attempt to determine relevant this terminal information.Because this register device does not comprise any information of relevant CT 30, therefore the first mobile service server contacts with the second mobile service server 14.The second mobile service server is checked table 46, finds that therefrom the terminal 30 with sign 30003 belongs to node 3 (step 62).So this information just returns to the first mobile service server.Then, the first mobile service server in view of the above with node 3 in the 3rd mobile service server 16 contact (step 64).The 3rd mobile service server is checked HDB54, therefrom obtains KI and sends to the first mobile service server, makes the position upgrade and is carried out.After receiving this KI, the first mobile service server 12 just it is given to a RE18.So RE18 just carries out the authentication checks (step 66) to this terminal.In check, RE sends a so-called inquiry to CT.Terminal sends one to replying of inquiring about, and this is replied according to the pre-programmed authentication information that receives when terminal is carried out initial programming and calculates.Reply in RE be included in KI in information compare, correctly meet the information that is included in the KI in other words if reply, just the position is upgraded.It is well-known in this technical field how carrying out this renewal, and in standard ETS 300 693 detailed description is arranged.Also have many different modes can be used for carrying out this authentication checks in addition.If the check of step 68 obtains the result that negates, this terminal just is left in the basket, and executing location is upgraded, and therefore refuses this accessing terminal to network (step 70).If the check of step 68 obtains definite results, RE is just with this advisory first mobile service server.So the first mobile service server upgrades VDB with relevant this terminal information, makes VDB36 be filled with the sign 30003 of this terminal, home node is a node 3, that connected is a RE18, and KI is KEY30003, shown in nethermost that row among Fig. 2 C.Then, advisory the 3rd mobile service server that the first mobile service server upgrades the executed position, thereby the 3rd mobile service server update HDB, make access node be listed as for terminal 30 be changed to node 30, shown in nethermost that row of HDB among Fig. 2 B.So just the VDB of access node and the HDB of home node have been carried out upgrading (step 72).The VDB of the original place of the advisory terminal node that the 3rd mobile service server has moved terminal again, the VDB that notice mobile service server is tackled it mutually by the information of deleting relevant CT carries out the position renewal.Because this is the VDB52 of home node, so all are more carried out in the 3rd mobile service server in new capital the position of VDB.
When a terminal disconnected, this terminal mobile service server that just it is connected with this advisory was so the mobile service server of this access node is just left out the clauses and subclauses of relevant this terminal from VDB.Described mobile service server is also notified the mobile service server of home node, makes it delete the clauses and subclauses that relate to access node in the HDB, thereby the row of the access node in the HDB just do not contain this terminal information.If CT loses suddenly and the contacting of a mobile service server, so just can not carry out this deletion.
More than Gai Shu method for optimizing change by different way.In this preferred embodiment, KI is stored in the VDB.Like this, access node just need be whenever terminal all will contact with home node with the acquisition KI when a radio switchboard forwards another radio switchboard to and moves in access node.VDB equally also can not store the information of this relevant KI.In this case, the mobile service server in the access node is carried out when the interior position of access node is upgraded at every turn and all must be contacted with the mobile service server of home node.If the mobile service interchanger of access node only is connected with a RE, that is just no problem.Yet,, just have a large amount of communication between these two nodes if there are many RE to be connected with access node.Authentication checks also not necessarily will be carried out in RE, also can just carry out in the mobile service server.Authentication process also can carry out in a diverse area of system.For example, place, a center can be arranged in network, for example in the second mobile service server of Fig. 1 or in center authentication server, for example be connected with all mobile service server by a computer network, be all CT execution authentication checks of network.In this case, inquiry will be distributed to each radio switchboard and/or mobile service server, collect therefrom and reply accordingly, test in this center.The reason that focuses on like this may be in order to obtain higher confidentiality, makes that sensitive KI is unlikely to transmit everywhere on the net.
What summarize above is the method for being followed under position renewal situation.Under the situation that a terminal is connected in system and move to from a geographic area at a terminal and all follow this method under the situation of another geographic area and handle.The example of the another kind of situation of wanting question blank 46 will be described below, just the situation when incoming call is arranged.Face will describe in conjunction with Fig. 1,2A, 2B, 2C and 5 in this case, and Fig. 5 wherein shows the flow chart of foundation to the method for the calling of a cordless terminal in the network.
Suppose that at first CT30 is in the zone of the first mobile service server 12 now, and incoming call is to be initiated by the fixed terminal 55 (second terminal) that is connected on the public network 11.In this preferred embodiment of the present invention, all incoming calls are all received by the second mobile service server, and other mobile service server can only directly contact with public network when breathing out.
What at first take place is that the second mobile service server receives a request and sets up a request (step 74) from the calling of second terminal 55 to CT30.This request is to utilize the sign of terminal 30003 to send.So the second mobile service server, 14 look-up tables 46 find that at the table end this terminal belongs to the 3rd mobile service server 16 (step 76).Like this, the second mobile service server is set up a traffic path from fixed terminal 55 to itself, and gives the 3rd mobile service server 16 with control.Therefore, the 3rd mobile service server is consulted HDB54, finds that in nethermost delegation this node is just in access node 1 (step 78).Then, the 3rd mobile service server 16 sends a request to the first mobile service server 12, request paging cordless terminal 30, if the summary of traffic permission is like this, this depend on cordless terminal activated which business (if any words).So the first mobile service server 12 is consulted VDB36, find that terminal 30 is to contact (step 80) with first radio switchboard 18.Like this, the first mobile service server is just ordered this terminal (step 82) of the first radio switchboard paging.When carrying out paging, first radio switchboard makes each BS that is connected with it all send a paging signal by air interface on paging channel.CT30 just responds after receiving this paging signal, should sign one of them base station, for example is that the highest base station of signal to noise ratio.After this, the first mobile service server is set up it by a RE and a BS and is connected to this part traffic of CT30, and another part traffic that the 3rd mobile service server is set up by it between the first mobile service server and the second mobile service server is connected.Set up as previously described at last, connect (step 84) thereby finished the traffic of setting up from fixed terminal to cordless terminal to this part of fixed terminal 55.
Traffic is connected in the above this method for optimizing and sets up from the 3rd mobile service server to the first mobile service server from the second mobile service server to the, three mobile service servers again.Like this, all incoming call traffics all pass through home node, because all business are all in this node processing.So, from the terminal in the access node home node just is given in the request of service, handle by it, resemble for example Call Forwarding.This function also can be distributed into all or some business and handle in access node.Traffic connects also can directly 1 foundation from node 2 to node.In such embodiments, the second mobile service server just is not given to control the 3rd mobile service server, but retentive control, the required information of calling out is set up in inquiry, for example which node is terminal visiting, and allows node 1 ask paging then, if permission.
As seen from Figure 1, directly be connected between node 1 and the node 3.In this case, the signaling between these two nodes will be passed through node 2 with being connected all.Certainly, node 1 and node 3 also can directly interconnect.
Incoming call is to utilize to wish that the number or the sign of the cordless terminal of contact carry out with it in the preferred embodiment of above outline.Paging here also is to use this number.In another embodiment of the present invention, such paging can realize with a special-purpose paging number of selecting for this reason.This special-purpose paging number can be selected in home node or in access node, because each mobile service server all has one section special-purpose paging number to use for paging.If special-purpose paging number is selected in home node, this number will send to access node with the paging request certainly.
In the preferred embodiment of above explanation, all incoming calls are all received by the second mobile service server.Yet, call out also and can receive by any mobile service server, perhaps receive by mobile service server as home node.
When in above preferred network, breathing out, cordless terminal contacts with the mobile service server of the intranodal of being visited, the mobile service server of access node contacts with the mobile service server of home node again, control is given to the mobile service server of home node.So, set up calling from home node, if the summary of traffic permission.Like this, all exhalation are in fact all handled by home node.What make an exception is urgent call, such as being undertaken by access node at the number 112 of Sweden with in number 911, the permission of the U.S..Reason is can be better for example to connect local fire department under the situation of fire having certainly like this, particularly when two nodes are far off.Perhaps, also can allow set up to call out, some or all summary of traffic are stored in the VDB of access node, make mobile service server there can carry out the business of the service that some or all permission terminals obtain by access node.
The above-mentioned different operating of carrying out in different mobile service servers is realized in control device 31,38,48, so they have the device of all these tasks of execution.These devices are rendered as some forms of being furnished with the processor of respective memory.It is contemplated that with an independent device and handle all these functions, so this device also is to be rendered as the form that some are furnished with the processor of respective memory.
But many correct parts are arranged in the present invention.For example, VDB can contain the information that more transfers from HDB, as summary of traffic and so on.When can upgrading in the position, this information is given to VDB.Adopt this mode, the mobile service server of access node just needn't per call all will contact with home node.VDB and HDB also need not to be the part of mobile service server, can be databases by the mobile service server access.
Fig. 6 shows second embodiment of private telecommunication network of the present invention, has omitted all RE and base station for brevity among the figure.Though public network and fixed terminal are not shown among the figure, private network 10 can be connected with such public network certainly.In addition, same label is used for indicating same device.
Between these two kinds of private network difference is only arranged is the first mobile service server 12 also accepts separately table 56 and 58 with the 3rd mobile service server 16 respectively in the mode identical with the second mobile service server.These tables are identical, therefore needn't contact with other mobile service servers in order to obtain information really, thereby reduce the signaling amount that will carry out.So also make things convenient for each mobile service server directly to receive incoming call from public network.The shortcoming of this embodiment is to need a kind of function of upgrading these tables simultaneously.
Further change and be shown in Fig. 7.There is shown the network that constitutes by the third embodiment of the present invention, with difference shown in Figure 6 be allocation lists not of all mobile service server.Each control device 31,38 all is connected with server 8 with 48, and this connection can be the computer network form.Mobile service server 12,14 and 16 can access server 8.Disposed in the server 8 and contained about the table of the information of each terminal and home node thereof and the appropriate device of storage and retrieving information.
Table shown in Fig. 2 A, 2B and the 2C, HDB and VDB only show the short address of each node.In fact, an address of node may be very long, thereby will take many spaces.In order to shorten the length of table, VDB and HDB, they can only contain the pointer that points to an address search table.Each the interior project of row that is designated as node, home node or access node represents that is pointed to a specific address position in the address search table, can find the real address of node in this position, contacts with node corresponding with this address.
Discussed above is to loosen the sign of terminal and the constraint between the node under it, and this has simplified the mode that can change the home node of cordless terminal greatly.This also makes to the cordless terminal selection marker in the no netting more convenient, need not select number in given finite interval fully, but can use the number of all distribution.Loosen constraint above-mentioned, as mentioned above, really can be more easy so that in network of the present invention, change home node.Illustrate below in conjunction with Fig. 1 and Fig. 8 how this realizes, wherein Fig. 8 shows the flow chart of the method for the home node that upgrades a CT.
The control device 31,38 and 48 of each mobile service server or node has function or the device of carrying out above-mentioned renewal.Each such control device is configured as the CT that registers and carries out and upgrade in the VDB of node separately.Therefore, if for example terminal 30 will change its home node into node 1 from node 3, this renewal will be by control device 48 controls of node 3 so.
Be that example illustrates the renewal situation below with CT30.The 3rd mobile service server 16 is old in other words home nodes at that time, measures the time (step 92) that CT 30 has stayed in the zone of the first mobile service server 12.Then, it is with this time compare with a thresholding (step 94).For this reason, home node, or the mobile service server of this home node certain device that can insert, relevant each terminal of storage has been visited other nodes information how long under the given time cycle.This time here is the time that has recorded at interval in for example one month total time.Thresholding is set to the percentage of the time that terminal is connected in the time interval of this month here in network.Therefore, the 3rd mobile service server 16 is measured the time in the zone that CT 30 have been in the first mobile service server 12, and the thresholding of certain percentage of the time of on is compared with being set to terminal in network with it.If measurement result surpasses thresholding (step 96), just the home node of CT30 is changed into node 1 (step 100) from node 3.If thresholding does not surpass (step 96), just not carry out home node and upgrade, the 3rd mobile service server continues to measure (step 98).The time interval of measuring is preferably quite long, at least one month for example, and the percentage of time registered is in 50% to 90% the scope of total time of registering in any zone in a zone, preferably about 70%.Therefore, surpassed 70% of this time if cordless terminal is in the zone of the first mobile service server 12, first node will be changed into new home node automatically.Can change thresholding in many ways, to obtain safe registration.The time interval of measuring must be chosen to both be long enough to guarantee to be subjected to access node to be in stable pattern, and being short to again is enough to make the unlikely hysteresis of registration too big.Percentage must be chosen to make the position significantly to change and trigger the home node change, still allow other nodes of visit simultaneously.
This measurement is easy to be carried out by the 3rd mobile service server, because HDB54 comprises all information of relevant access node, and the corresponding entry in the access node row is just deleted when terminal is left this node.Therefore control device 48 is very easy to be respectively each node that can visit and keeps an independently clock, makes to be registered as in HDB in terminal to trigger this clock when being in the intranodal related with clock and carry out timing.
Adopt the method for above general introduction,, will change the home node of this CT so automatically if a CT more or less chronicity is in the access node.Like this, just can avoid a large amount of unnecessary signalings transmission between new, old home node, thereby make the capacity of network can more effectively be used for the place that to use, promptly transmit traffic.The artificial home node registration that can also avoid trouble in addition.
Obviously, said method needn't be leaveed no choice but carry out in old home node.It also can be carried out in new home node, perhaps carries out in the node 2 that contains table.It can also be carried out in the such separate server of server shown in Fig. 7, if each mobile service server all can insert an outside VDB outside the device of handling VDB.Situation also can be that old home node is carried out and measured, enters a judgement to whether changing home node, and by this server or the actual execution change of management node.Yet, preferably in old home node, measure and enter a judgement changing home node because it contain all of relevant terminal must information, other variety of ways can need a large amount of signalings.If HDB is an independent community that the mobile service server can insert, can certainly allow it measure and upgrade.Another kind of possible modification is the time that terminal has disconnected of considering when judgement changes home node.This can by be registered in the given interval terminal registered for real time of visiting a node and with this real time be registered as that the real time that is in other intranodals respectively compares and these real times relatively finished mutually.Perhaps, also can be counter of each node configuration, and the counter of a node uses in this node region within the jurisdiction duration just to increase progressively at every next cordless terminal.If the value of such counter has surpassed a threshold value, just start and change home node.The mode of the change enforcement of judgment execute a judgement process that another kind is possible is that percentage is carried out different weightings.If wherein there is node smaller and can not handle too many traffic, can be assigned to more than its treatable terminal for fear of this node so, this mode may be highly significant.Thresholding above-mentioned also needn't be leaveed no choice but time of considering that terminal is connected in network, and can be set to certain percentage of whole measuring intervals of TIME.
Below in conjunction with Fig. 1,2A, the 9 and 10 explanations actual more news of carrying out how after measuring like this, Fig. 9 wherein shows the content as the HDB of the node 1 of new home node, and Figure 10 shows the flow chart of the method for the home node in the actual change network shown in Figure 1.
Fig. 9 shows the HDB34 of node 1, and the HDB of the node 3 shown in this HDB and Fig. 2 B is similar.What register is other the CT (promptly being the CT that belongs to the CT of node 1 rather than belong to node 3) except tangible, and main difference is that this table has also comprised and is designated 30003 terminal, and this terminal belonged to node 3 in the past.This HDB contains relevant to the information of node 1 as each CT of home node, and the summary of traffic of all these CT all has PROFILE1.The one CT is masked as 10001, is positioned at node 1, has KI KEY10001.The 2nd CT is masked as 10002, just in access node 2, has KI KEY10002.The 3rd CT is masked as 10003, just in access node 3, has KI KEY10003.Last this CT30 is masked as 30003, and registration has KI KEY30003 when access node 1.
, according to after determining to change home node in conjunction with the method for Fig. 8 explanation the information of relevant CT30 is copied to as the new node 1 (step 102) of home node from the node 3 interior HDB54 as old home node at the control device 48 of node 3.After the control device 31 of node 1 receives this information, just CT30 is recorded in the HDB34 of node 1, is about to this HDB (step 104) of information typing that is received.After this, the control device 48 of the control device of node 1 31 notice nodes 3, the entry HDB34 that packed into.So, the control device 38 of the control device 48 notice nodes 2 of node 3, the essential renewal of carrying out his-and-hers watches.Then, the control device 38 of node 2 upgrades its table (step 106) by changing into node 1 from node 3 to the home node setting of CT30.Like this, node 1 just is set to new home node.Connect for all the new traffics that need set up, this new home node is of all business of control.Yet, connecting for any traffic that during changing like this, continues, old home node still plays a part home node.Node 2 is notice node 3 now, and table upgrades.So only be left last step of this method.Therefore the 3rd mobile service server deletes the information (step 108) of relevant CT30 in the NDB54.Deletion needn't be carried out immediately.Any to set up when still be home node and still do not delete this information during the traffic in continuation at node 3 be very important on the contrary handling.
Adopt said method, can make the service that need obtain still have other activities of handling by new home node simultaneously by the connection that continues to get off of old home node processing to CT.This other activities can be the relevant information that has message to continue in the user's voice mailbox, or transmit SMS (short message service) message or notify this terminal of calling party just busy.
Said method can certainly comprise and upgrade a VDB who contains this terminal information, make this VDB be updated to address that comprises new home node or the pointer that points to it.This step is preferably in to be carried out after table upgrades as early as possible, carries out before that is to say relevant this terminal information in the HDB of the old home node of deletion.In this case, the 3rd mobile service server is immediate command node 1 after receiving from the table 46 of node 2 updated information, and promptly the current place of terminal node upgrades VDB.
The reason of carrying out this method in the above described manner is to have bulk information between two nodes will transmit when changing home node.Nor transmit this information when wishing in network, to have a large amount of traffic.Therefore this renewal is preferably in and carries out night.Simultaneously, also wish the almost actual immediately home node that changes really, if influence the user of network in order to avoid when needs visit HDB, carrying out this change.This available method of summarizing is above very rapidly finished.
Adopt the method for above-mentioned renewal home node just can obtain a kind of automatic more method of the home node of new terminal.The sign of terminal does not need to do any change, thereby terminal can continue to use when changing home node.This method also guarantees automatic renewing imputation node safely by thresholding suitably is set.
Certainly, it is automatically that renewal needn't be leaveed no choice but, and also can manually carry out, and promptly according to the request from the terminal use, changes table, HDB and VDB by the business personnel.
The network that makes up by the present invention can further be modified as and save all radio switchboards, and the base station directly is connected with the mobile service server.In this case, a mobile service server will comprise some mobile service processing capacities that former RE has.So each base station or the telecommunication line that passes through separately are connected with the mobile service server, perhaps several base stations are connected with the mobile service server by some multiplex/demultiplex light devices.Under the situation of not using radio switchboard, all mobile service processing capacities all will be incorporated into the mobile service server.Owing to be the DECT system, so the mobile service server also contains the compression/decompression compression apparatus, therefore to avoid the voice signal of using for another CT that is connected with same mobile service server or such signal of using for another server in the same network are decompressed.The unnecessary compression and decompression that so just can avoid otherwise can in this system, carry out.
Above combination has the mobile service server of function of exchange, and the invention has been described.Certainly, the present invention also can be used with the mobile service server that does not have such function.In addition, the present invention is not limited to use in including only the network of cordless terminal, comprises that the network of cordless terminal and fixed terminal also can adopt the present invention.The present invention also is not limited to the mobile service server, and it can be used for any essential private telecommunication network of handling mobile service.
Certainly, the present invention is not limited to these embodiment described above and illustrated in the accompanying drawings.Therefore, the many variations that can draw according to spirit of the present invention all should be listed the given scope of patent protection of the present invention of appended claims in.
