Description
Technical Field
The present invention relates to the field of network identification, and in particular, to a user identification system and a registration, service and route configuration method.
Background
The NGN (Next Generation Networks, Next-band Networks) is a broad category, and aims to reform the infrastructure of the existing telecommunication network and information industry to support wider services, and the network can be composed of a fixed network, a mobile network, an IP network, an access network and the like, so that the NGN can support various services to realize the intercommunication with the existing network.
The NGN network comprises the following functions: the system comprises an application layer, a network control layer, a transmission layer and a management layer, wherein different layers can communicate with each other. The application layer realizes the functions of authentication, charging, directory, safety, browsing, searching, navigation, format conversion and the like; the application layer not only provides services for mass users, but also provides service support for an operation support system and a service provider; network control layer: providing end-to-end call/session control, and controlling the bottom layer automatic switching transmission network and processing the signaling; the transmission layer provides one-layer switching and transmission, two-layer switching and three-layer switching and/or routing functions; the management plane provides remote and local management functions.
Although NGN integrates voice data and multimedia services, which is an innovation of conventional network technology, it also brings some new features in user management. For example, how to implement effective user access authentication in the NGN network system, guarantee user service security, implement quick and effective user maintenance, and the like.
However, in the prior art, the NGN uniquely identifies a user through the device port, that is, each user line or port is used as a user and identified by an e.164 number, and the user number corresponds to the physical interface or line. The user and the number do not move, and the user data is stored in the call server in a scattered manner without authentication. The NGN system has diluted the user location information so it is of little interest to identify the user by location information.
In addition, in the NGN field, the existing solutions mostly identify devices, and since NGN must have a good access capability due to multiple user device accesses caused by the interconnection of various networks in the NGN network, it is suggested in ITU-T y.2001 that an individual user translates from name/number to a routable effective address by a name/number method, thereby establishing transmission. These methods include e.164 encoding method, URL (Uniform Resource Locator), UNS (Uniform name System), URI (Uniform Resource Identifier), and the like.
The technology takes the routable address as the identifier of the equipment, lacks guarantee in the aspect of safety, and is easy to pretend to be fake and deceive; moreover, although the address and name are used as the identifier of the device and can represent the user to a certain extent, the user and the device cannot be separated, the device does not have good mobility and portability, and other services or intelligent functions cannot be directly attached to the identifier.
In view of the above disadvantages of the device identification technology, a concept of UCI (universal communications Identifier) is proposed in the prior art. The UCI is used to identify users in the NGN and introduces personal user agents and server system agents so that it can be location independent.
However, the technology is designed only for the hierarchy structure and the business process of the UCI, and the networking layout of the next generation of network overall situation is not considered; in addition, there are security deficiencies in the registration and authentication process of NGN users; in addition, the management of the personal user agent and the routing update are not discussed.

In this embodiment, the individual user agent units, the UCI data center units, and the server system agent units are all distributed, that is, one individual user agent unit corresponds to one UCI data center unit and one server system agent unit. The distributed UCI data center unit is used as a database for pre-storing the universal communication identifier information of the user terminal and providing original data such as addition, deletion, update, query and the like of the universal communication identifier information for the personal user agent unit, wherein the universal communication identifier information comprises a uniform user number, a user name, a password, a position parameter, an authority parameter for accessing a specific service, local terminal capability identification and the like, the uniform user number, the user name and the password are required to be provided, and the position parameter, the authority parameter for accessing the specific service and the local terminal capability identification are optional.

Wherein the server system proxy element corresponds to a function provided by a legacy operator; the main functions of the personal user agent unit include preliminary identification of the user terminal and interaction with the user, in the process, the personal user agent unit can perform capability negotiation with the user terminal, determine the position of the terminal, the supported functions and/or the load capacity and/or bandwidth of the local network, provide some simple local functions for the user terminal (such as access and registration authentication of the user terminal), accept service requests of some users (such as service identification and service application), find a proper server system agent unit for the services, and forward the proper server system agent unit to the corresponding server system agent unit; the server system agent unit matches corresponding services for the personal user agent unit in the network according to the request sent by the personal user agent unit, and provides the services for the user terminal through the personal user agent unit.
The system of the present invention is deployed comprehensively in conjunction with the structure of an NGN, such as an IMS (IP multimedia subsystem), as shown in fig. 2. Wherein the user terminal may be considered as a user holder of the UCI; the interaction with the outside is mainly personal user agent unit and resource access control subsystem, personal user agent unit and S-CSCF (serving call session control function), server system agent unit and gateway.
The CSCF (call session control function) in fig. 2 is responsible for resource allocation, session state, ordering of user traffic, querying user authentication and traffic data, and performing session processing tasks. The CSCFs are classified into P-CSCFs (proxy call session control functions), and home network CSCFs. The P-CSCF is the first contact point of a user in the IMS and is a proxy for the CSCF in the home network, which can be further divided into an I-CSCF (access call session control function) which is an entry of the network and is responsible for allocating the S-CSCF serving the user and an S-CSCF (serving call session control function) which is a device that actually handles the session state.
The MGCF (Media Gateway Control Function) provides the capability of controlling a Media Gateway through a standard interface, and controls a call state of Media channel connection Control, allocation and release of resources, and change of resources. The BGCF (break Gateway Control Function) connects a call to a PSTN (public switched telephone network), selects a network to be exported to the PSTN, and selects an MGCF in the network. The BGCF and MGCF may be in any home, visited and third party network. An AS (Application Server) provides a value-added IP multimedia service to a user.
Although the Home Subscriber Server (HSS) and the UCI data center unit are both used as databases for storing user data, the user data information in the HSS is mostly set by the user before accessing the network, and there is no addition or deletion of data, but only update of data (such as service customization information) and support is insufficient in cross-network access and operation for the same user; and the data of the UCI data center relates to a series of processes of adding, registering, identifying and the like after a new user acquires the UCI, and meanwhile, the UCI can support and complete cross-network access of the same user on multiple terminals by providing the data to the PUA.
The concept of interface is introduced in fig. 2, and the connection relationship of the network entities in this embodiment is described in detail. Depending on the scope of the interacting entities, the interfaces may be further divided into internal and external interfaces, as shown in fig. 3:
five internal reference points are included: uup interface, Upp interface, Upi interface, Ups interface and Ump interface, wherein,
the Uup interface is the interface between the user terminal with UCI information and the personal user agent unit. The functions of the device comprise: the method comprises the steps of initial identification and position determination of a user terminal by a personal user agent unit, and capability negotiation and interaction between a network where the user terminal is located and a used terminal and the personal user agent unit.
The Upp interface is an interactive interface between individual user agent units, and the functions of the Upp interface are mainly capability negotiation between each other and routing of positions, so that the most appropriate access is found for a user terminal.
The Upi interface is the interface of the individual user agent unit and the UCI data center unit, and the functions are mainly as follows: the UCI data center unit provides user information for the individual user agent unit to process, and the individual user agent unit calls data in the CUI data center unit to carry out preliminary identification on the user terminal and stores the related information in the UCI data center unit.
The Ups interface is an interface between the individual user agent unit and the server system agent unit, and its functions include: the personal user agent unit searches the corresponding server system agent unit, submits the data negotiated with the user to the server system agent unit, the personal user agent unit registers and uses the service to the server system agent unit, the server system agent unit provides the corresponding service for the personal user agent unit through the load network, and the personal user agent unit and the server system agent unit are in the binding state in the service process.
Ump interface is the interface between UCI management center unit and individual user agent unit, and its functions include: the UCI management center unit newly-added service definition broadcasts to all PUAs; the increase or decrease of the number of PUAs is notified to the UCI management center, and the UCI broadcasts to other individual user agent units and reconfigures the route.
The three external interfaces include: upr interface, and/or Upc interface, and/or Usg interface; wherein,
the Upr interface is an interface between the personal user agent unit and the resource access control subsystem, and its functions include: the calling of the capability negotiation function in the resource access control subsystem by the personal user agent unit and the support of the capability negotiation function of the personal user agent unit by the resource access control subsystem are mainly capability interaction processes, including checking the resource availability, and checking whether the requested bandwidth is consistent with the preset bandwidth and the bandwidth used by the user by the admission control function.
The Upc interface is an interface between a personal user agent unit and an S-CSCF (serving call session control function), and includes: after the communication logic channel is established, the personal user agent unit sends a notice to the serving CSCF, and the serving CSCF confirms the notice, thereby entering a session service flow, and after the completion, an opposite link is removed.
The Usg interface is an interface between the server system proxy element and the gateway and functions primarily as a server system proxy element accessing the corresponding load network through the gateway to obtain the relevant services from the carrier network, and as a network providing services to the server system proxy element through the gateway so that the services can be bound at the server system proxy element.
To further describe the mutual functions and cooperation among the entities in the user identification system, the present invention is explained in more detail by means of the following registration flowchart of the user terminal with UCI information, as shown in fig. 4, including the following steps:
A. the user terminal with the universal communication identifier information sends registration request information to the personal user agent unit;
B. the personal user agent unit verifies the information of the user terminal; when the user terminal accesses the network, the personal user agent distributes a client number to the user terminal, the system transmits the parameter group after the encryption algorithm to the client, after the terminal receives the parameter, the parameter group is compared with the uniform user identification stored by the universal communication identifier after the same algorithm, and the verification is passed if the result is the same.
C. The personal user agent unit appoints a server system agent unit according to the service information; for example, when a user terminal has a universal communication identifier, accesses a next generation network through an IP device, and wants to implement a video transmission function with a mobile phone, a personal user agent in a home network processes its request, searches for an operating network providing the function, and specifies a server system agent unit in the operating network.
D. The personal user agent unit informs the user terminal that the registration is successful;
E. the user terminal initiates a binding request to the server system agent unit;
F. the server system agent unit verifies the validity of the binding request, compares the authority parameter of accessing the specific service in the universal communication identifier with the service request, if the service request is in the authority parameter range, the service request is legal, and confirms the user terminal to the personal user agent unit. The authority parameter for accessing the specific service includes a service identifier, a service access authority identifier, and the like.
G. The server system agent unit sends a binding success response to the user terminal.
Wherein, the data needed by the individual user agent unit in the confirmation process is extracted from the UCI data center unit. In addition, after the personal user agent unit confirms the service information of the user terminal, the personal user agent unit not only informs the user terminal that the registration is successful, but also sends a message to the server system agent unit to inform the user that the user is about to access. The process is carried out before the user terminal sends the binding request to the server system proxy unit, a time delay can be agreed, and only the binding request arriving in the time delay is processed, so that the safety of the server system proxy unit is improved.
The invention achieves the combination of distributed deployment and centralized deployment of PUA through the management of the user data by the UCI management center, and can conveniently carry out service flow management and routing management.
The UCI management center unit has a configuration capability of operating well for new services (including new services due to an increase in the capabilities of the network, terminal equipment, or new services due to an adjustment to the qualification of the user). Fig. 5 depicts a service configuration flow of the UCI management center unit: when the UCI management center unit defines a new service capability, the UCI management center unit informs the individual user agent unit to register the service, so that the service can be verified when the user terminal is accessed; the personal user agent unit then informs the server system that the agent unit should configure the service, while network and terminal device capabilities, user qualifications, etc. should be configured. For example, the original UCI management center unit defines a new mobile terminal video service, and through the service configuration flow, it notifies the individual subscriber unit to register the video service, and notifies the server system unit to perform configuration.
The UCI management center unit may manage the route in case of a change of the route, such as a new personal user agent unit joining the network, or a personal user agent unit terminating or exiting the network for various reasons. Fig. 6 shows a route management process of the UCI management center unit: when a new personal user agent unit joins the network, the UCI management center unit is informed; the universal communication identifier management center unit records the basic information of newly added personal user agent unit, and monitors the running state and updating state of the personal user agent unit, wherein the basic information comprises: location, and/or local network load capacity, and/or time of use; the UCI management center unit broadcasts the address of the personal user agent unit, and the related personal user agent unit configures the routing information of the personal user agent unit.
The service flow for realizing the call establishment by utilizing the invention is shown in figure 7, and a calling party has a user terminal 1 with UCI information to identify in a personal user agent unit 1; the personal user agent unit 1 confirms the user terminal 1 by extracting and processing the data of the UCI data center unit 1; the caller's personal user agent unit 1 confirms the target user terminal 2 and contacts the target user's personal user agent unit 2; the personal user agent unit 2 confirms the user terminal 2 by calling and processing the data of the UCI data center unit 2; the personal user agent unit 2 responds to the personal user agent unit 1 and provides necessary information for channel establishment and maintenance (such as application of the protocol and parameters of the channel, etc.); the calling party personal user agent unit 1 provides the server system agent unit 1 with the necessary information (such as rights information and service parameters, etc.) to keep the channel open. X, Y, Z is that before, during and after the channel is established, the states of the terminal and the service can be interacted among various entities; in the figure, the thick solid line represents the traffic channel and the thin solid line represents the signaling channel. In addition, a complete service flow can be completed by one bearer network or multiple bearer networks according to different conditions.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
