The present invention relates to a procedure and a system that allows a better mobility for a mobile station (MS) in a wireless local loop. The invention enables the mobile station's mobility area (MA), defined by the home base station (BS) or home cell of the mobile station, to be extended to the areas of other base stations and/or cells connected to the same local exchange (LE).
Description
The present invention relates to a mobility method that is used to enlarge a radio subscriber platform as in the beginning of claim 1, defining.And, the invention still further relates to an ambulant system that is used to enlarge a radio subscriber platform as in the beginning of claim 13, defining.
In a radio home loop (WLL), a terminal installation is connected to an access node (AN) by a radio link.A base station is arranged between terminal installation and access node, on the contrary all call signal that will on a radio channel, send by this base station by terminal installation through access node be transferred to a public telephone network or.Access node is connected to telephone exchange with V5.1 or V5.2 agreement.
With ETSI (ETSI) standard definition of all ETS (European Telecommunication Standard) 300 324 and the ETS 300 347 series all open interface (V5.1 or V5.2) between an access node and local switch.All users that all V5 interfaces can will belong to that in fact separate an or wired or wireless local network with the standard interface of telephone exchange couple together.Dynamic concentrator interface V5.2 with all ETS 300 347-1 and 347-2 conformance to standard is made up of one or more (1-16) PCM (pulse code modulation) circuit.Article one, the PCM circuit comprises 32 channels, and every channel all has the transfer rate of one 64 kbit/s (kilobits/second), and promptly total transfer rate is 2048 kbit/s.The support of V5.2 interface is as being used in all analog telephones in the public telephone network, all numeral reservations as the reservation of all fundamental sums system of ISDN (integrated services digital network), and other the analog or digital terminal equipment on all semifixed connections basis.
In current all radio systems, the mobility that enlarges a subscriber board is impossible and/or is very difficult at least.When subscriber board is connected to that the subscribers feeder of a cable network WLL and user wish can be from his original position (home) base station or during outside, zone temporary transient access of home cell, the user must rent, and buys or use a GSM (global system that is used for all mobile communication) operator's a mobile phone.In all more advanced systems, subscriber board, as a travelling carriage, comprise two subscriber identification modules (STM), defined one of them and be used in the work of a GSM network and define another being used for work at a WLL environment of a cable telephone network.In this case, the user makes a selection by his/her end-point arrangement about used network.A system based on GSM/DCS (global system/data communication system that is used for all mobile communication) technology, it also is possible that subscriber board comprises a technology solution based on these two systems.In this case, the user also selects used network by his/her subscriber board.
By a V5.2 interface be connected to a local switch all WLL access nodes can not by a V5 interface will for gsm system be typical signaling data be transferred to all other access node or be transferred to a mobile communications network.With current technology, all WLL users' mobility is expanded to another WLL access node of the switch of same cable network, expand a WLL access node of the switch of another cable network to, or the mobile switching centre that expands a gsm system to is impossible.
The objective of the invention is to eliminate above-mentioned all problems.A special purpose of the present invention is to announce a kind of new method and a kind of new system, and they make even realize that in a radio home loop mobility of a subscriber board all becomes possibility.
All characteristics about expression feature of the present invention please refer to claims.
The present invention relates to a kind of mobility method that is used for enlarging at the terminal installation of a radio home loop environment.For the sake of clarity, we state that " terminal installation " can be actual device itself in this application, as a travelling carriage, or a user; For example, the moving area of terminal installation definition is meaned such moving area, we have been the user definitions that are connected with terminal installation to his identification module should the zone.At least can realize the local network discussed with two kinds of methods: a mobile communications network is carried out suitable modification so that it can be used in the radio home loop (GSM/DCS1800), or with one to be used in the system of a technology (GSM/DCS1800 connecting system) in the mobile communication system, this system comprises a local switch and an access node that is connected with local switch.Access node preferentially is connected to local switch by a V5 interface with conformance to standard above-mentioned.And this system comprises a terminal installation and a base station that is connected with local switch by access node, and this base station is used for all call signals of transmission between access node and terminal installation.Terminal installation and base station communicate by a radio link.Further, with base station and the access node that links, can only be with a kind of like this terminal installation by its original position base station and the mode that connects of access node, the original position network and the predetermined moving area of terminal installation limited.With the arrangement of base stations of many all other networks around access node, make terminal installation receive all information signals from all base stations on every side, and, determine the base station that terminal installation is being communicated by letter with it, as knowing from mobile communication technology according to these information signals.
According to the present invention, set up a signaling channel in the interface between local switch and access node, this channel is used to transmit the information relevant with mobile management.Signaling channel can be one or for good and all or dynamically be retained in time slot in the V5 interface.Further, according to the present invention, when terminal installation shifts out or moves on to its outward flange of coverage area of original position base station, signal strength signal intensity is low there, we determine another base station on the basis of the information that terminal installation provides, this information can comprise, for example, a terminal installation can be set up the inventory of all base stations of radio communication with it, mainly communicates by letter with another access node that is connected with local switch in other base station.Further, terminal installation is handed over to other base station, and notes this handover in the local switch in the network in position.If terminal installation can not be set up radio communication with other access node that is connected to local switch, then to belong to a radio circuit also be possible in other base station, the radio net data that will be used for terminal installation in this case, give mobile communications network by communications together with other possible information, the installing terminal device is a casual user in mobile communications network, so allow to use terminal installation according to the common all definition of terminal installation in mobile communications network.The user is dynamically set up as a casual user, because usually the operator produces a user in HLR (home position register), so this and common GSM network management have a deviation.The Any user that user who sets up as a casual user is taken as in the GSM network is treated.
Compared with the prior art, method of the present invention has advantage, promptly when the user is in the coverage area of the base station of his WLL access node, the all common service that is provided by cable network can be provided for he, as all more cheap operating costs, and the user also has unlimited mobility, allows to be handed at another access node of same local switch the inside or is handed over to a mobile communications network.
So, the present invention can with same subscriber board make a user's in a cable network mobility from the WLL access node expand to all other access node or expand a mobile communications network to, so the user can sign one about his/her mobility is enlarged, so that allow to be handed over to the agreement of several WLL access nodes and a mobile communications network with the operator.
A consistency that further advantage is all telephone numbers of the present invention when compared with the prior art.This means when a user in system of the present invention be during a common mobile communications network the inside, he can reach and distribute to his/her common telephone number in wired telephone network.
In one embodiment of the invention, also produce a signaling channel in the interface between local switch and second access node, this signaling channel is used to transmit the information relevant with the ambulant management of terminal installation, the inventory of some base stations as portion, terminal installation can be according to implementing a handover to those base stations for all definition of mobile communications network.Further, produce a signaling channel that is used for command transmitting between all access nodes in the local switch between first access node and second access node.When terminal installation being handed over to second access node, will be used as an auxiliary signaling in the signaling of this channel.
On the other hand, it also is possible that the user is handed over to a mobile communications network, in one embodiment, between local switch and mobile communications network, set up a second signaling channel, this signaling channel is used to transmit the information relevant with the ambulant management of terminal installation, the inventory of some base stations as portion, terminal installation can be according to implementing a handover to those base stations for all definition of mobile communications network.Further, set up a signaling channel that is used for command transmitting between first access node and mobile communications network in the local switch between first access node and mobile communications network.When terminal installation is handed over to mobile communications network, will be used as an auxiliary signaling in the signaling of this channel.
When the user has an ongoing calling and user to be handed over to another access node that is connected with same local switch by the access node from user oneself, an access node that agreement at first selects the user to be handed off to of implementing in local switch is then to distributed a temporary transient V5/L3 address in the access node that the user is handed off to by the user of handover.The V5/L3 address is a given user's who defines in a given V5 interface of an identification address.Every user must have an independent V5/L3 address that is different from all other users.
Further, it in another access node the inside an influence that for good and all has been defined as the foundation and the scanning certainty of the voice path that the user that belongs to a different access node and or be handed off to another access node carries out or has been subjected to using all addresses that differently are provided with common use by common V5/L3 address realm, unique user of these address nonrecognition, but discern one and dynamically be handed over to access node according to the present invention, and be defined in user in the access node of same cable network switch the inside, perhaps be subjected to influence with the address realm of a V5 interface that separates, be total address realm that all users' dynamic handover keeps the V5 interface in this case, as by given to this invention.In a back situation, defined two or more V5 interfaces between access node and local switch: 1 to n interface is generally used for all wire users connection and 1 to n V5 interface from the access node to the local switch and is used for all users that method of handover according to the present invention is handed off to access node.When access node when the inside of user,, set up calling with user's oneself V5/L3 address according to all specification requirements of V5 at him.When the user being handed over to another access node, set up calling with a V5/L3 address value that separates of temporarily distributing to the user according to normal V5 signaling with method of handover.In other words, the user has permanent his a V5/L3 address in access node the inside, he mainly moves in the zone of this address, be the operator with user definition in this zone, and the address definition that n is borrowed is in the V5/L3 address realm, and this is relevant with all callings or all access nodes in all zones that the user is visiting them.Agreement in local switch manages these V5/L3 addresses of borrowing according to the place that the user is handed off in each situation.From the viewpoint of agreement, the V5/L3 address of the free time that can will borrow gives any WLL user who is handed off to another access node who is defined in the local network.About all V5/L3 address by consultative management, any WLL user who is defined in the local switch can use this address.When WLL user got back to his access node regional, agreement was released to the V5/L3 address that the user borrows, so this address is idle, can give any needs its user.In order to finish handover, the change of connection not only in local switch but also in all access nodes by synchronously, and disconnect the calling of at first setting up in common mode by access node.
On the other hand, if we receive a calling that is addressed to terminal installation, and terminal installation is when a mobile communications network the inside, then with an agreement of in local switch, implementing, be identified for the radio net data of terminal installation from access node, and begin from local switch by the call setup of a signaling channel to mobile communications network.Further, before terminal installation is handed over to mobile communications network, carry out all work relevant with call manager by the agreement of in local switch, implementing.In addition, must verify the right of accessing mobile communication network for users.On the basis of this checking,, then prevent the handover of terminal installation to mobile communications network if find not exist the right of visit.If user's operator and the operator the who user is being handed over to its mobile communications network also do not sign a so-called roaming agreement, a kind of like this situation then may take place.
Further, preferentially by agreement execution of in local switch, implementing or the control all working relevant, as be handed over to a different channel or access node with call manager.
In addition, in one embodiment of the invention, terminal installation is inserted other base station and the right of access node is verified, if there is no the right of Jie Ruing prevents that then terminal installation from arriving the handover of that base station or access node.
In addition, the present invention relates to aforesaid one and be used for enlarging the ambulant system of a terminal installation at a radio home loop environment.According to the present invention, the interface between local switch and access node comprises that one is used to transmit and signaling channel about the relevant information of the mobile management of terminal installation.This system preferentially also comprises second access node and second base station that is connected to second access node that preferentially are connected to local switch by a V5 interface.Interface between local switch and second access node comprises that a second is used to transmit and signaling channel about the relevant information of the mobile management of terminal installation.Further, this system comprises the 3rd signaling channel, this channel has been based upon in the local switch between first access node and second access node, and with this channel be used between all access nodes transmission with about the relevant information of the mobile management of terminal installation.In addition, set up the 4th signaling channel in local switch between above-mentioned first and second signaling channels that are connected to a mobile communications network, described the 4th signaling channel allows directly to communicate by letter between access node and mobile communications network.
Below, we will present invention is described with reference to appended all figure under the help of some examples of all embodiment of the present invention, wherein
Fig. 1 is figure according to system of the present invention of an expression; With
Fig. 2 is another figure according to system of the present invention of expression.
The system of describing in Fig. 1 comprises a local switch LE that all functions an of handover and roaming agreement P1 and its needs are arranged.And this system comprises first and second access node AN, ANn, and they are connected to local switch LE by a V5.2 interface.A base station BS, BS n are connected respectively to each access node AN, ANn.The coverage area of base station BS is corresponding with the moving area of a mobile station MS, and the coverage area of base station BS n has defined moving area MAn." moving area " means a zone of distributing to an independent WLL user, and the user moves in this zone and in this zone usually.In this application, can enough synthetic expressions " base station coverage area " or " sub-district coverage area " replace term " moving area ".So MA is a distinctive parameter of user, the zone that its definition user can move thereon with his/her travelling carriage.Tangible purpose of the present invention provides the possibility of a moving area that dynamically extends one's service.
Fig. 1 further illustrates at access node AN, the signal transmission in the V5 interface between ANn and the local switch LE.The signaling (PSTN is a public telephone switching network) that interface can transmit common PSTN can be transmitted the signaling of ISDN (integrated services digital network) again.In addition, interface comprises a channel for all V5 control messages (V5 control) and the reservation of all V5 interface BCC (bearer channel control) message.Further, according to the present invention, interface comprises a signaling channel S1 who is used for the signal transmission of data relevant with the handover of mobile station MS and other mobile management data, S2.Fig. 1 is the 3rd signaling channel S3 of expression further, and this signaling channel is based upon among the local switch LE between signaling channel S1 and S2.Signaling channel S3 can be used at all access node AN, irrespectively transmits information with all other network componentses between the ANn.
Below, we are described a preferential embodiment of the present invention with reference to the Fig. 1 at appended Zhu Tuzhong.As mentioned above, for from one with the access node AN of the conformance to standard of ETS 300 347 series to all other access node or support all Network Transmission of GSM technology with about the relevant signaling of the mobile management of mobile station MS, in the V5.2 interface, defined a signaling channel S1 who separates, S2.When mobile station MS shifted out its coverage area MA of base station BS, base station BS was the base station BS of a WLL access node AN who is connected with a cable network in this example, and access node AN requires mobile station MS that a all handover candidates' inventory is provided.Access node AN will give agreement P1 in local switch LE about the message transmission of the base station of all suggestions by signaling channel S1.
On the basis by access node AN information transmitted, the agreement P1 in local switch LE selects access node ANn as the main access node that mobile station MS can be handed over to it.If handover work is successful, then local switch LE sets up a signaling link S3 at these two access node AN between the ANn.Access node AN, ANn consult all operations that must carry out with signaling channel S3 between them.
In case when mobile station MS being handed over to other access node ANn, the access node ANn of reception should fact notice local switch LE by signaling channel S2.Local switch LE stored information arrives correct access node ANn so can will be addressed to all guiding calls of mobile station MS.
If mobile station MS has an ongoing calling in above-mentioned handover procedure, if and all access node AN, ANn has determined calling is handed over to other access node ANn, and then access node ANn will be by signaling channel S2 this handoff notification agreement P1.With common scanning differently, all time slots in the V5.2 interface of agreement P1 scan setting between access node ANn and local switch, so that find out an idle time slot, and, set up a calling by the V5 interface of access node ANn according to the specification requirement of all ETS 300 347 series.Agreement P1 gives all access node AN, ANn by all signaling channel S2 and S1 with the call notification of setting up.Agreement P1 is from access node AN, and both receive a message ANn, and this message points out that they have been ready to transmit voice path, and with not only in local switch LE but also at two access node AN, the change of the connection among the ANn is synchronous.According to the specification requirement of all ETS 300 347 series, under the control of agreement P1, initial calling of setting up by access node AN is disconnected with the V5 interface be connected.
Similarly, system shown in Figure 2 comprises a local switch LE that all functions an of handover and roaming agreement P1 and its needs are arranged.And local switch has a customer data base DB, and this database is used to store the required information about all users, as to every user-defined moving area.System further comprises an access node AN who is connected to local switch LE by a V5.2 interface.A base station BS is connected to access node AN, and the coverage area of base station BS is with corresponding to the moving area MA of a mobile station MS definition in this example.
Fig. 2 further specifies the signal transmission in the V5 interface between access node AN and local switch LE.The signaling (PSTN is a public telephone switching network) that interface can transmit common PSTN can be transmitted the signaling of ISDN (integrated services digital network) again.In addition, interface comprises a channel for all V5 control messages (V5 control) and the reservation of all V5 interface BCC (bearer channel control) message.Further, according to the present invention, interface comprises a signaling channel S1 who is used for the signal transmission of data relevant with the handover of mobile station MS and other mobile management data.Fig. 2 is second signaling channel S2 from LE to moving exchanging center MSC of local switch of expression further.Can use the information of signaling channel S2 transmission about the user between local switch and mobile switching centre.In addition, system shown in Figure 2 comprises the 3rd a signaling channel S4 who sets up between all signaling channel S1 and S2 in local switch.
And Fig. 2 illustrates that an itself is known structure of mobile communication network; As long as the access node of saying a radio home loop is not only corresponding to a MSC (mobile switching centre) but also just enough corresponding to a BSC (basic switching center), MSC and BSC are in Fig. 2 in a box ANn who is represented by all dotted lines.
Below, with reference to Fig. 2, and work as a mobile station MS with reference to one and can only set up radio communication with a base station BS n who works a mobile communications network the inside, and situation about taking place when a WLL user who belongs to a cable telephone network at first dynamically being appointed as a user in a local GSM system in mobile communications network is described another preferential embodiment of the present invention.
When the subscriber board MS that is connected to the local switch LE in cable telephone network with a radiotechnics shifts out its coverage area MA of base station, the WLL access node AN that works in the local switch LE the inside of a cable network, by being added to the signaling channel S1 of V5.2 interface, a signal is sent to protocol software P1 in local switch LE, point out that subscriber board MS has been moved out to territory, a low place.
Protocol software P1 in local switch LE checks the information that is sent by access node AN and mobile station MS, and this information and all limiting values that defined by the operator are compared.If protocol software P1 decision is handed over to the GSM network with the user, then it sends to home position register HLR in the moving exchanging center MSC of GSM network by signaling channel S2 with a message, so as will by the user notification of handover it.If the user provide is provided home position register HLR, then it sends to protocol software P1 in local switch LE with corresponding information, so sets up a signaling channel S4 in the local switch of the protocol software between signaling channel S1 and S2.
The access node AN of home position register HLR in the switching center of gsm system inside the local switch LE at cable network sends a requirement, requirement obtains about the distinctive data of the radio net of mobile station MS, and the user is noted as a casual user in its system.In order to finish handover, the protocol software P1 of home position register HLR notice in local switch LE, user are temporarily in global GSM network the inside.On the basis of this notice, protocol software P1 imports a distinguishing mark to the user in customer data base DB, points out that the user is temporarily in global GSM network the inside.
If receive a calling that is addressed to the user in the local switch LE of cable network, then call control system knows that from customer data base DB subscriber board is the scope outside at its access node AN.The call control system of local switch LE is handed over to protocol software P1 with call manager, and protocol software P1 sends a requirement to access node AN then, and requirement obtains about the distinctive information of user's radio net.After receiving this information, agreement P1 begins to carry out call setup by signaling channel S2.
If in same geographic area, there are two or more GSM operators carrying out work, if then the operator of user's original position network has signed a roaming agreement with each operator, he can be chosen in the roaming condition operator who calling is handed over to he user by oneself.
