METHOD OF IMPLEMENTATION OF ADMINISTRATION OF MOBILITY OF FIXED TERMINALS IN A COMMUNICATIONS NETWORK
FIELD OF THE INVENTION The present invention relates to the field of communication technology, in particular to a method and system for implementing the mobile administration of fixed terminals in a communications network. BACKGROUND OF THE INVENTION In a mobile communication network, the information of mobile subscribers is centrally managed by means of a unified home location register (HLR), in order to provide mobile administration to mobile terminals. HLR also serves as the authentication center for mobile subscribers, it serves as an entity in which mobile subscriber data is stored for authentication and encryption. As the home location information of mobile subscribers is stored in the HLR, therefore the mobile communication network is enabled to make the terminals movable and can effectively mask the difference in service capacity between terminal offices, in order to provide unified services for the network.
Ref .: 171902 However, in a fixed communication network, subscriber authority data and new service data are stored in the exchange of terminal offices, and a terminal office accesses the database directly to obtain corresponding information, and reach the relevant call processing function. As a result, the number of the subscriber must be limited to the terminal office, that is, the data must be limited in the terminal office, and it is impossible for the subscribers to roam the local network and migrate through offices, etc .; In addition, since the services are provided by terminal offices and there are different types of equipment in terminal offices, the capabilities of equipment service provision in the individual terminal offices are different from one another; as a result, in existing fixed communications networks, it is difficult to provide or generalize unified services throughout the network; and, the pattern of data storage in the aforementioned fixed communication networks also brings a problem that smart services are difficult to activate in terminal offices. However, there is a unified home location registry (HLR), which serves as a database for centrally managing the information of mobile subscribers, and serves as the authentication center for mobile subscribers to store data from mobile subscribers for authentication and encryption in an existing mobile communication network. As shown in Figure 1, the mobile switching center (MSC) is interconnected with the HLR through the MAP (mobile application part), the location information of the subscribers, the information of new services stored in the HLR, the Mobile Switching Center (MSC), the Gateway Mobile Switching Center (GMSC) interacts with the HLR through a MAP protocol to obtain location information of the subscribers and information of new services and achieves basic call functions for subscribers. Apparently, since the mobile HLR is oriented to services for mobile communication networks, it is interconnected with the Mobile Switching Center through the MAP protocol. The MAP protocol is a protocol for mobile communication networks, it is not supported by exchanges in fixed networks, in such a way that it can not be applied in fixed communication networks. In fixed communication networks, intelligent services without an access code are activated in terminal offices. In which call-type intelligent services need to be activated by the calling terminal office, the intelligent services on the caller's side, such as a fixed prepaid service, are activated as follows: the access code is inserted before the number dialed by the calling terminal office, and is sent to the SSP (Service Switching Point) for service activation; however, there are currently many types of exchanges in terminal offices in networks, it is impossible to insert the access code automatically before the dialed number; therefore, it is difficult to implement the activation of the aforementioned service. In which intelligent services of the called type are activated by the called terminal office; Smart services on the called side can include Simultaneous Call Signing Service, Personalized Ring Tones Service (CRBT), Unified Messaging Service (UM), and CENTREX (for its acronym in English for Central Office Exchange Service) of wide area, etc., in which the Service of Simultaneous Call Signs refers to the subscriber being able to register a certain number of numbers of Simultaneous Call Signs, and all the Simultaneous Call Signal numbers will sound simultaneously or in sequence when the subscriber has an incoming call, in order to locate the calling subscriber in time; The CRBT Service means that a subscriber in a fixed network can customize several signal tones of the connection phase of the call for the current telephone, for example, when the calling party is listening for the ring tone in the phase of the ringing signal, several spoken phrases can be customized to replace the ringing tone so that the calling party hears the personalized spoken words, the Unified Messaging Service, that is, the Universal Personal Number, refers to a subscriber has a personal number and when the subscriber is traveling, by means of the dialing register, the call to that personal number would be automatically connected to the registered number; the wide area CENTREX means that a part of the subscribers in exchange of a fixed network become virtual in a group of subscribers, in which the subscribers can mark with shortened numbers one another to implement the exchange function of private bifurcation. The activation of the intelligence services on the called side is as follows: the destination terminal office (ie the called terminal office) inserts the access before the called number, which is sent to the SSP
(service switching point) to activate the service; after the service is activated, SSP reconnects the call to the destination terminal office; however, the called terminal office is usually unable to connect the call to the SSP; even if the terminal call office connects the call to the SSP, the SSP needs to reconnect the call to the terminal office after the service processing ends, the called terminal office would again send the call to the SSP for activation, this results in the repeated activation and waste of the voice channel, and even call failure. Therefore, it is impossible for the above techniques to avoid repeated activation to the SSP.

DETAILED DESCRIPTION OF THE INVENTION The main object of the present invention is to establish a Home Location Register for fixed subscriber terminals, that is, an integrated HLR, in which subscriber terminal subscriber information in a fixed communication network is centrally stored and managed. Subscriber information includes subscriber addressing information and smart service subscription information, etc., therefore subscriber terminals in the fixed communication network are enabled to have characteristics of the subscriber terminals in the network of subscribers. mobile communication, such as roaming, migration through offices without changing telephone number, etc., and the problem of activation of intelligent services through the entire network is resolved through the Home Location Registry. Meanwhile, the integrated HLR can also function as the Home Location Register of the PHS network, PLMN network, and the 3G network, in order to provide the integrated carriers of the future with merged services of the fixed and mobile communication networks. In the present invention, first, a centralized database, i.e., the integrated HLR, is provided for the fixed subscriber terminals, for storing subscriber addressing information and service subscription information, which allows fixed subscribers are roaming through offices, and provide unified services for fixed subscribers; secondly, the centralized database for fixed subscriber terminals incorporates mobile HLR functions at the same time, and an integrated HLR is made, that is, it provides a unified database for PSTN, PHS, PLMN, and 3G at the same time, which is used to store the addressing information of the mobile subscribers and the fixed subscriber and the corresponding subscription service information, that service subscription information may be: the subscriber's actual number, subscription information Fixed Payment Service, Simultaneous Call Sign Service subscription information, Custom call sign service subscription information, Unified Message Service subscription information, and CENTREX subscription information (Central Office Exchange Service ) of wide area, etc., in order to develop the combined number of emission services merged numbers of the fixed and mobile communication network, CENTREX (Central Office Exchange Service) integrated, and activation of intelligent services throughout the network, etc .; finally, the integrated HLR also provides ISUP (ISDN User Part) interfaces based on fixed communication networks and INAP signaling interfaces, so that they establish an interface directly to the fixed communication network through the ISUP, INAP protocols. In addition, the integrated HLR provides a MAP signaling interface based on the mobile network, to interconnect with a PHS network and a 3G network, so that the data stored in the integrated HLR could be shared with SCP (Service Control Points). ) in the intelligent network, in order to deploy the corresponding intelligent services and implement the activation of intelligent services throughout the entire network. In the present invention, all calls are first sent to the integrated HLR, the real numbers of the subscriber terminals are obtained in the integrated HLR, and the call connection processing is performed in accordance with the real numbers. As a result, with the present invention, it is possible to implement the provision of combined numbers, NP fixed network (number portability), and intelligent services that are activated throughout the network. The issuance of combined numbers means the centralized management of the numbers of subscribers in the communication network, each subscriber would have two numbers, one is a public logical number (for example, a mobile telephone number retained by a mobile subscriber), the other is a physical number that determines the domestic location of the subscriber, although the physical number can be migrated through offices and changed when needed, the logical number remains unchanged, due to the existence of the integrated HLR, the subscriber numbers issued to the subscribers Individuals can then be coded and issued in accordance with practical requirements, for example, the issue of a combined number can be implemented between fixed subscribers, and also between fixed and mobile subscribers, in addition, the NP function is also implemented in the fixed network, that is, the numbers of the subscribers in the fixed communication network already n or are restricted to use in fixed physical locations; rather, as mobile subscribers, the retained subscriber number would remain unchanged, and can normally deploy communication services, when the physical location changes, this provides a great convenience for fixed subscriber terminals to make use of communication networks. . Such intelligent services that are activated throughout the network are implemented in the following way: subscription information of subscribers' intelligent services is stored in the integrated HLR, for the call of the subscriber with intelligent services authority, after analyzing the subscription information of intelligent services, the integrated HLR automatically inserts the corresponding smart service access code before the called number, and directs the call to the SSP (Service Switching Point), to achieve service activation corresponding smart. Therefore, in the present invention, the intelligent services on the call side are all activated centrally by the calling terminal office after consulting the integrated HLR, in order to avoid the problem that the call can not reach its destination due to the activation of repeated services to the SSP, which exists during the activation of intelligent services implemented by the terminal office called in the prior art. The present invention is briefly described as lines above. The embodiments of the method described in the present invention are described below, together with the appended figures, as shown in Figure 3, specifically comprising the following steps: Step 31: establishing an integrated Home Location Register (i.e. integrated HLR) ); in the integrated HLR, it stores the subscriber information of the subscriber terminals in the individual networks respectively, including subscriber addressing information and service subscription information, etc.; that individual network includes fixed communication networks and mobile communication networks, particularly, including PSTN, PLMN, 3G, and PHS networks, etc .; step 32: the integrated HLR is interconnected with PSTN, PLMN, 3G and PHS networks, respectively, that is, the exchanges in the individual networks exchange information with the integrated HLR respectively, to obtain subscriber information from the corresponding subscriber terminals, the Subscriber information obtained can be the subscriber's real number, intelligent service access code, etc .; step 33: the exchanges in the individual networks achieve the corresponding call connection processing according to the subscriber information obtained from the subscriber terminals; In the present invention, the aforementioned service processing method can be implemented with the following two solutions in the fixed communications network: solution based on ISUP signaling, and solution based on INAP signaling; wherein, the flow of processing of services based on ISUP signaling is shown in figure 4, it comprises the following stages: stage 41: the calling subscriber in a terminal office 1 (the terminal office to which the calling subscriber belongs) ) initiates a call, and the call is sent to the integrated HLR, that is, sends an IAM (by initials in English of Initial Address Message) to the integrated HLR; stage 42: after searching and analyzing the number of the call, if the subscribers who initiate the call have registered the corresponding service and require that the calling number be converted, the integrated HLR would return the called number converted to exchange in the office terminal 1 through an ACM (for the acronym in English of Complete Address Message); stage 43: meanwhile, after searching and analyzing the called number, if the subscribers who initiate the call have registered the corresponding service and require the call number to be converted, the integrated HLR sends the link between the terminal release office and the Integrated HLR through a REL (Release Message), and returns the converted call number at the same time, so that the exchange in the terminal office can re-analyze the called number and re-select the channel with the message REL; step 44: after receiving the REL message, the tgerminal office 1 sends an RLC (Complete Release Message) to the integrated HLR, disconnects the relay circuit connected to the integrated HLR; stage 45: the exchange in the terminal office 1 sends an IAM to the terminal office 2 (the terminal office to which the called subscriber belongs) according to the information obtained from the integrated HLR; stage 46, after receiving the IAM from the terminal office 1, the terminal office 2 returns an ACM to the terminal office 1. The terminal office restarts a new call according to the numbers that are called and the calls of the HLR, the procedure of the Particular call processing is identical to that of the prior art, the only difference being that the calling and called numbers have been changed.
Wherein, the service processing flow based on INAP signaling is shown in Figure 5, it comprises the following steps: step 51: for the call initiated by a subscriber in a terminal office in a fixed network, and the corresponding intelligent service is activated through an SSP, then the SSP reports the numbers that call and the calls to the integrated HLR through an InitialDP (initials of initial detection point); step 52: the integrated HLR configures the corresponding event detection point, and requests the SSP to report the detected events at the detection point corresponding to the integrated HLR; stage 53: the integrated HLR issues the "connect" operation to the SSP; step 54: after detecting the corresponding detection point events, the SSP reports to the integrated HLR, for example, after detecting the corresponding detection point events, such as call attempt, information acquisition, or information analysis, the SSP reports to the integrated HLR; stage 55: after receiving the reported detection point events, the integrated HLR disconnects the corresponding connection through the SSP; wherein, if step 52, 54 and 55 are not executed, the "Connect" operation in step 53 issues the issuance of "end of session" operation to the SSP through the integrated HLR. With the HLR integrated in the present invention, integrated services can also be implemented in fixed and mobile communication networks, such integrated services are: centralizing fixed and mobile subscribers in a group of virtual subscribers and effecting in this group of subscribers various types of processing calls, including the integrated CENTREX, issuance of combined numbers for subscribers in fixed and mobile communication networks, migration of PHS subscribers (eg Handyphone Personal System Subscribers) to 3G subscribers without changing the telephone number, etc. For example, in the case where a subscriber in a fixed exchange initiates a call to a subscriber in a mobile communication network, the particular service flow is shown in Figure 6, comprising the following steps: Step 61, fixed exchanges, such as LS (fixed network terminal office), MS (serial office), G (gateway interchange), and TS (Commutation to Collect), etc., send a call to the integrated HLR through the IAM, that is, when a subscriber in the communication network initiates a call, the exchange sends the call first to the integrated HLR, and in the IAM it carries the DN (mobile subscriber number) of the called subscriber; Stage. 62: the integrated HLR sends a PRN request (Request for provision of roaming number) to the VMSC (virtual mobile switching center) of the mobile terminal office; Step 63: the VMSC of the mobile terminal office sends a PRN request response to the integrated HLR, in response it provides the mobile roaming number; Step 64: the integrated HLR sends the mobile roaming number obtained to the fixed exchange, such as the fixed terminal office; the serial office, the exchange of the gateway or the commutation to collect, through the REL message, - Stage 65: the fixed exchange sends an IAM message to the GMSC (mobile gateway switching center), in the IAM message it bears the number mobile roaming obtained from the called subscriber; Step 66: the GMSC routes the call to the VMSC through the IAM message, and the subsequent call processing is performed by means of the VMSC, the call processing flow is identical to that of the prior art. With the present invention, a centralized database, ie integrated HLR, is available to the fixed communication network, with respect to the mobile communication network, in addition, the existence of the integrated HLR can effectively mask the difference between the capacity to provide services for individual terminal offices and provide unified services for subscribers in the fixed network. Therefore, the fixed communication network is enabled to have the service characteristics of the mobile communication network, that is, with respect to mobile subscribers, it can also be implemented so that the fixed subscribers migrate through offices without changing the number telephone; In addition, with the integrated HLR, it is also possible to combine fixed subscribers and mobile subscribers, to deploy services including the issuance of the combined number to fixed subscribers and mobile subscribers, the migration of PHS subscribers to 3G networks without changing the telephone number, CENTREX integrated, and activation of intelligent services through the entire network, etc. What was described above are only the most preferred embodiments of the present invention, and the protected scope of the present invention is not limited thereto. The variation and replacement that those skilled in the art in the technical area described in the present invention can make will fall within the protected scope of the present invention. Therefore, the protected scope of the present invention should be that defined in the claims.
