Description

Access system and method for integrating different access technologies

The present invention relates to a convergence technology of a mobile communication network, and more particularly to an access system and method for combining different access technologies. Background technique

Since the 1980s, public wireless mobile communication technology has entered people's lives. Nearly 30 years have passed, and the development of public wireless mobile communication technology has experienced two eras of analog mobile communication technology and digital mobile communication technology. Digital mobile communication technology has experienced the development of second generation (2G), third generation (3G), and fourth generation (4G) mobile communication technologies. Moreover, with the further development of mobile communication technologies, digital mobile communication technologies will also have fifth-generation and sixth-generation mobile communication technologies in the future. At the same time, there are also close-range wireless communication technologies such as WiFi (Wireless Fidelity), ZigBee, and Bluetooth.

Among them, 2G includes Global System for Mobile Communications (GSM) technology and Code Division Multiple Access (CDMA), and 3G includes Wideband Code Division Multiple Access (WCDMA). Technology, CDMA-2000 technology, and Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) technology, followed by 4G in addition to the long-term evolution of various technologies in 3G (LTE, Long) Term Evolution technology, including Worldwide Interoperability for Microwave Access (WiMAX) technology. At present, when these technologies are applied, a technology should be a network, and networks can communicate with each other. In other words, terminals in two networks can interact. However, the equipment, operation and maintenance, management, and even the operators of each network are independent of each other. Users must use different user identity modules (SIM, Subscriber Identity Module). Cards, different terminals, and even applications from different operators are required to obtain services for different wireless mobile communication technologies.

In fact, for the user, all that is required is communication, that is, the transmission of information such as sound, text, pictures and video to a desired recipient with a certain quality of service. As for the use of wireless mobile communication technology to achieve the transmission of information, it is a problem that operators and equipment manufacturers need to consider.

Since different wireless mobile communication technologies are subject to their own technical limitations, the services that can be provided will vary. In general, the emerging wireless mobile communication technology will be compatible with the wireless mobile communication technology that appeared before. For example, in the era of 3G and 4G, the communication bandwidth is greatly improved, so that the video service can be practical, but the user still needs 2G. A well-solved voice communication service. For example: Compared with the Universal Mobile Telecommunications System (UMTS) technology, the general packet radio service (GPRS, General Packet Radio Service) has poor data transmission capability, but can still meet many low bandwidths better. Business needs.

In addition, due to the operator's business strategy and other reasons, the wireless coverage of different wireless mobile communication technologies may be different. For example, where 3G has not been covered, 2G may have covered very well. . Even if the same good coverage is obtained at the same time, under certain bursts and special conditions, it may happen that the capacity of one wireless mobile communication technology has been used up, and the capacity of another wireless mobile communication technology is still sufficient, but Due to terminal and operational reasons, these redundant communication resources are not available.

Moreover, for operators, the difference in wireless mobile communication technology will lead to different devices, which inevitably leads to repeated construction of many devices. In fact, the differences in these wireless mobile communication technologies are reflected in the wireless communication part, which only occupies part of the entire communication system. Since the birth and development of different wireless mobile communication technologies are relatively independent, the processing methods for the same user communication requirements will be different. If these wireless mobile communication technologies are integrated Analysis and integration will undoubtedly increase the sharing degree of equipment, thus saving a lot of resources and energy. As can be seen from the above description, in the prior art, different wireless mobile communication technologies are independent of each other, and the terminal generally can only access a network provided by the wireless mobile communication technology, and is performed through the accessed network. The communication service cannot simultaneously utilize the network provided by multiple wireless mobile communication technologies, so that the networks provided by various wireless mobile communication technologies cannot cooperate to provide communication services, which causes high cost and poor user experience.

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

The invention integrates an access system with different access technologies. As shown in FIG. 1, the system includes: a converged terminal 11, an access network 12, and a converged core network 13; the converged core network 13 further includes: a converged access switch 131, And HSS 132; wherein

The converged terminal 11 is configured to send an access request including the user identifier and the access technology identifier to the converged access switch 131 through the access network 12 when the network that needs to access the different access technologies is used; After receiving the access request including the user identifier and the access technology identifier, and determining that the self-resource allows the converged terminal to access, the authentication process is completed by interacting with the information of the HSS 132 including the user identifier and the access technology identifier. , to achieve network access with different access technologies.

The converged terminal 11 is further configured to interact with the access network 12, the access network 12 and the converged access switch 131, and the message between the converged access switch 131 and the HSS 132 when the access location changes. , complete the location update process;

The access network 12 is further configured to complete a location update process by interacting with a message between the fusion terminal 11 and the fused access switch 131 when the access location of the fused terminal 11 changes.

The fused access switch 131 is further configured to complete a location update process by interacting with a message between the access network 12 and the HSS 132 when the access location of the fused terminal 11 changes; the HSS 132, When the access location for the converged terminal 11 changes, the location update process is completed by the message interaction with the converged access switch 131.

The converged core network 13 may further include a service server 133 for transmitting a corresponding message to the converged access switch 131 when it is determined that the traffic channel needs to be added, and/or deleted, and/or adjusted;

The converged access switch 131 is further configured to receive the corresponding cancellation sent by the service server 133. After the information, the addition, and/or deletion, and/or adjustment of the traffic channel between the converged terminal 11 and the access network 12 corresponding to the traffic channel are implemented according to the received corresponding message.

In the access system of the present invention, the access network 12 includes a wired access network and a radio access network. For the radio access technology, the access network 12 generally includes a base station and a base station controller. However, with the enhancement of the processing power of the processor and the Internet Protocol (IP) of the access network transmission, the element of the base station controller has been eliminated in the LTE system, and the base station directly connects with the core network, and the base station bears Most of the functions of the original base station controller. Therefore, the base station controller in the present invention is an optional network element, and whether or not the base station controller is equipped is determined by a specific access technology. In other words, the specific implementation of the access network is the same as the prior art. Whether or not the base station controller is equipped, the access network 12 and the converged access switch 131 are required to comply with the same protocol, so that the converged access switch 131 can be used for all access technologies. For wired access, the access network can be either existing or, of course, new.

The converged terminal 11, the access network 12, and the converged access switch 131 all support multiple access technologies, and use these access technologies to establish required information transmission between the converged terminal and a network that integrates different radio access technologies. aisle. The converged access switch 131 is part of the converged core network 13, which is equivalent to the edge and antenna of the converged core network 13, for collecting and distributing user traffic, and shielding the access network from the converged core network 13. The fused access switch 131 can shield the difference between different access technologies, so that the fused core network 13 does not have to be perceived, but can be completely used for these existing and existing access technologies, where the different accesses are The technology corresponds to the respective access network. In addition to the functions described above, the HSS 132 and the converged access switch 131 can also carry the functions of a Home Agent (HA) and a Foreign Agent (FA), respectively, to implement the Mobile IP function under the architecture of the present invention.

In addition to the channel management function and the mobility management function described above, the fused access switch 131 has a service management function corresponding to three types of data, namely, management air interface resources, user information, and service information. Among them, the channel management function, the mobile management function, and the service management function respectively It is responsible for the channel management module, the mobility management module, and the service management module of the converged access switch 131. The channel management module is responsible for the management of the air interface channel in the service range of the fused access switch, including adding, deleting, reconfiguring, and querying, and the corresponding air interface resources include: access network type, access network location, access network capacity, There are already channels and so on. The task of the mobility management module is to cooperate with the HSS 132 to manage the mobility of the converged terminal 11 so as to timely update the location of the converged terminal access network, so that it can be accessed by other terminals at any time, and the service continuity is maintained. Another function of the mobility management module is equivalent to the VLR (Visitor Location Register) in the prior art, that is, the data of the visited user is saved for query, and the corresponding user information includes: user identifier, available service identifier, and Right information, access location information of the used converged terminal, and the like. The service management module processes the services initiated or received by the user, and the main task is to find and forward the service request to the service server. For simple, versatile services, such as simple voice calls, the access switch can be handled independently of the service server. In order to speed up related queries and reduce the overhead of related messages, the converged access switch 13 can also create instances for all service requests within its own service scope, and perform targeted management. The corresponding service information may include: a service identifier and a corresponding service server list, configured to implement forwarding of the service request; the service instance may include: a service identifier, a service instance identifier, a service server address, a calling user information, and a called user. Information, etc. 2 is a schematic diagram of a data structure stored in a converged access switch. As shown in FIG. 2, service information includes services and service instances, user information corresponds to users, and air interface resources include channels and channel instances, based on saved service information and user information. Air interface resources, converged access switches complete channel service management, mobility management and channel management.

The interface between the access network 12 and the fused access switch 131 is established on a general packet transmission mechanism such as IP, so as to carry the fused terminal 11 between the network merging different access technologies and between the access network and the access switch. Signaling and services.

The HSS 132 stores and manages user information. The user information includes: a user number, an available service, an available resource, authentication information, and used converged terminal information. The information includes: terminal identifier, terminal status, and access location information of the terminal. The converged core network 13 is an information exchange mechanism that is applicable to all types of content and services and is common to all access technologies.

The service server 133 generally controls the implementation of the communication service, and the small-sized service, such as a peer-to-peer (P2P) voice communication service, can also be implemented in the converged access switch 131.

The specific processing of the converged terminal, the access network, the converged access switch, the HSS, and the service server in the system of the present invention will be described in detail below.

Based on the above system, the present invention also provides an access method for combining different access technologies. As shown in FIG. 3, the method includes the following steps:

Step 301: When accessing a network that is fused with different access technologies, the fused terminal sends an access request message including the user identifier and the access technology identifier to the fused access switch through the access network. Specifically, the fused terminal and the access network After the control channel is established, sending an access request message including the user identifier to the access network;

The access request message may further include: a terminal identifier, and the like.

Determining its own resources to allow the converged terminal to access means: The access network determines to allow the converged terminal to access according to its available resource status; wherein the access network determines the specific processing for allowing the converged terminal to access according to its available resource status The process can employ prior art.

When the access network determines that the converged terminal is not allowed to access according to its available resource status, the access network returns information of the access failure to the converged terminal. Specifically, the access failure information may be returned to the converged terminal by using an access request response message.

Before the merging terminal and the access network establish a control channel, the method may further include: after the merging terminal is powered on, according to a predetermined rule, the corresponding access technology and the base of the access network The station synchronizes and establishes a control channel.

The predetermined rules may be set according to requirements, such as: according to user preferences, user and operator agreement, or changes according to network conditions or business progress.

The number of the access networks is one or more. A wireless access technology typically corresponds to an access network.

Step 302: After the fused access switch receives the access request message, and determines that the self-resource allows the fused terminal to access, the accommodating process is completed by interacting with the information of the HSS including the user identifier and the access technology identifier to complete the authentication process. Network access for different access technologies.

Here, the determining the self resource allows the converged terminal to access, specifically:

The fused access switch determines that the fused terminal is allowed to access according to the available resource status of the fused access switch. The available resource status includes: a memory resource and an interface resource status. The fused access switch determines to allow the fused according to the available resource status. The specific processing of terminal access can adopt the prior art.

When the fused access switch determines that the fused terminal is not allowed to access according to its available resource status, it returns information of the access failure to the access network. After receiving the information, the access network returns the access failure information to the fused terminal. Specifically, the fused access switch may return the access failure information to the access network by using the access request response message, and the access network may return the access failure information to the fused terminal by using the access request response message.

The device performs the authentication process by interacting with the information of the HSS that includes the access technology identifier, and implements network access that integrates different access technologies, specifically:

After receiving the user authentication message, the HSS matches the user information in the message with the user information saved by the user, and after determining the matching, returns the user authentication information including the user's authentication information and the allowed access information to the fused access switch. Reply message After receiving the user authentication response message, the fused access switch returns an access request response message including the authentication information and the successful access information required for the air interface transmission corresponding to the fused terminal to the access network;

After receiving the access request response message, the access network sends a message including the successful access to the converged terminal.

After the HSS determines that the match cannot be matched, the user authentication response message containing the information that is not allowed to be accessed is returned to the fused access switch;

Correspondingly, after receiving the user authentication response message, the converged access switch returns an access request response message containing the information of the access failure to the access network;

After receiving the access request response message, the access network sends an access request response message including the information of the access failure to the convergence terminal;

After receiving the access request response message containing the failed information, the fused terminal may re-select an access technology and re-initiate the access request message, that is, re-execute steps 301-302 to enable access to different access technologies. In the network.

The operator has previously configured user information on the HSS.

After this step is completed, it indicates that the control channel between the converged terminal and the converged access switch has been established.

The method may further comprise:

When the access location of the converged terminal changes, the location update process is completed by the message exchange between the converged terminal and the access network, the access network and the converged access switch, and the converged access switch and the HSS;

Specifically, as shown in FIG. 4, the following steps are included:

Step 401: Send a location update message to the access network when the location of the fused terminal changes; where the location update message includes the user identifier and the access location information of the fused terminal; wherein, the period of the fused terminal through the access network Sex broadcast, you can know the location update message contains The access location information includes: a converged access switch address accessed by the converged terminal, a port accessing the converged access switch by the access network, a base station identifier, a sector identifier, and the like;

Step 402: After receiving the location update message, the access network forwards the location update message to the fused access switch.

Here, the location update message includes a user identifier and access location information of the converged terminal. The access location information in the forwarded location update message includes: a switch identifier, and a used switch port, which may not include access network specific information, such as a sector identifier, a base station identifier, and the like.

Step 403: After receiving the location update message, the converged access switch forwards the location update message to the HSS.

Here, the location update message includes a user identifier and access location information of the converged terminal. Step 404: After receiving the location update message, the HSS updates its own saved access location information of the converged terminal, and after the update, sends a location update success message to the converged access switch, where the HSS saves the fusion. The access location information of the terminal includes: an address of the converged access switch. Further, the method further includes: accessing the port of the converged access switch by the access network.

The location update success message can be sent through the location update response message;

When the update fails, the HSS sends a Location Update Reply message containing the reason for the failure to the Converged Access Switch.

The reason for the failure may be various, for example: the memory resource of the HSS itself may be insufficient, or the content of the message may be invalid; the reason for the failure is not the content of the present invention.

Step 405: After receiving the information that the location update succeeds, the fused access switch updates the access location information of the converged terminal that is saved by itself, and sends the information of the location update success to the access network after the update;

Here, the location update success message may be sent by the location update response message; when the update fails, the converged access switch sends the failure to the converged access switch. The location update response message for the cause.

Among them, there are various reasons for the failure of the update result, for example: The memory resources of the converged access switch itself may be insufficient. The reason for the failure is not the content of the present invention.

In the initial access process, the converged access switch has passed the HSS, and the access location information of the converged terminal is learned and saved.

After receiving the location update response message including the cause of the failure sent by the HSS, the location information of the convergence terminal is not updated, and the location update response message including the cause of the failure is directly returned to the access network.

Step 406: After receiving the information that the location update succeeds, the access network updates the access location information of the fusion terminal that is saved by itself, and after the update, sends the location update information to the fusion terminal.

Here, the location update success message may be sent by the location update response message; after the update fails, the access network sends a location update response message containing the cause of the failure to the convergence terminal.

Among them, there are many reasons for the failure of the update result, for example: It may be insufficient memory resources of the access network itself. The reason for the failure is not the content of the present invention.

During the initial access process, the access network has learned the access location information of the fusion terminal and saves it through the converged access switch.

After receiving the location update response message sent by the converged access switch and including the cause of the failure, the location information of the converged terminal is not updated, and the location update response including the cause of the failure is directly returned to the converged terminal. Message.

After receiving the location update response message including the cause of the failure, the converged terminal may resend the location update request to the access network, that is, re-execute steps 401-406.

As can be seen from the above description, in the present invention, the access technology and the mobile processing have been separated, and the unified mobile processing corresponds to different access technologies, thereby enabling the access technology and the mobile processing. Specifically, in the present invention, different access technologies only provide information channels between the converged terminal and the access network, and different access technologies may be accessed through corresponding access networks and converged access networks. The switch cooperates and shields; the converged access switch cooperates with the HSS to complete the mobile processing of the converged terminal and the service.

After the control channel between the fused terminal and the fused access switch is established, signaling related to other radio access technologies may be transmitted through the control channel, for example, enabling the access technology, adding a service channel message, and deleting a service. Channel messages, control messages, and more.

The method may further comprise:

When the service server determines that the service channel needs to be added, and/or deleted, and/or is adjusted according to the service requirement, the service server sends a corresponding message to the fused access switch, and the fused access switch implements the fused terminal according to the received corresponding message. The addition, and/or deletion, and/or adjustment of the traffic channel between access networks corresponding to the traffic channel.

The adjusted traffic channel and the newly added traffic channel may be different access technologies from the established traffic channel, and/or different from the established traffic channel, or may be established. The same access technology for the traffic channel.

The present invention will be further described in detail below with reference to the embodiments.

The application scenario of this embodiment is as follows: The converged terminal establishes a traffic channel through the access network 1 and the converged access switch 1. The newly added traffic channel has different radio access technologies from the established traffic channel, namely: establishing a traffic channel with the access network 2, and the access network 2 and the access network 1 have different converged access switches, namely: The access network 2 is connected to the converged access switch 2. In this embodiment, a method for implementing a new service channel, as shown in FIG. 5, includes the following steps:

Step 501: The service server determines, according to the service requirement, that a new service channel needs to be added, and sends an increased channel message to the fused access switch 1;

Here, the adding channel message includes: a requirement for a newly added channel, such as: bandwidth, delay, jitter, and the like. The specific processing procedure of the service server to determine the requirement of the newly added channel is related to the specific service, and is not of the interest of the present invention, and the prior art can be adopted.

Step 502: After receiving the message, the fused access switch 1 creates a session, and forwards the channel information to the access network 1;

Here, the specific process of creating a session can be prior art.

The adding channel message includes: session information, and a requirement for the newly added channel. The session information may include: a session identifier, and an address of the fused access switch 1; : Bandwidth, delay, jitter, etc.

Step 503: After receiving the message, the access network 1 forwards the add channel message to the fused terminal. Here, the add channel message includes: requirements for the newly added channel, such as: bandwidth, delay, jitter, and the like.

Step 504: After receiving the message, the fused terminal determines the corresponding radio access technology according to the requirement of the newly added channel in the channel information, and sends an increase channel request to the corresponding access network of the corresponding radio access technology.

Here, according to the requirement for adding a new channel in the channel message, the specific processing procedure for determining the corresponding radio access technology may adopt the prior art.

When the corresponding processing of the corresponding radio access technology has not been started, the converged terminal first starts the processing function corresponding to its own radio access technology, including: enabling radio frequency, baseband, searching for the most suitable access cell, and accessing the search. In the most suitable access cell to the network, an additional channel request is then sent to the corresponding access network of the corresponding radio access technology.

The corresponding access network of the corresponding radio access technology refers to: the access network 2.

Step 505: After the access network 2 agrees to add the channel, it returns an increased channel response to the converged terminal. Here, the access network 2 determines whether to agree to increase the channel according to its own resource utilization situation. The specific process of agreeing to increase the channel can be applied to the prior art. If the channel is not agreed to be added, a refusal to increase channel message is returned to the fused terminal.

Step 506: After receiving the increased channel response, the converged terminal cooperates with the access network 2 to complete the establishment of the new service channel, and reports the new access and the new service channel to the converged access switch 2 through the access network 2. set up;

Here, the specific processing process in which the converged terminal cooperates with the access network 2 to complete the establishment of the new service channel is a prior art, and details are not described herein again.

The content reported to the converged access switch 2 includes the access location information of the converged terminal, and the corresponding information of the channel to increase the session, such as the session identifier, the address of the converged access switch 1, and the like.

Step 507: The fused access switch 2 records or updates the information of the fused terminal, and sends a channel addition message to the fused access switch 1, indicating that the channel operation is completed.

Here, the channel addition message includes a newly added traffic channel identifier and corresponding access location information of the terminal.

Step 508: The fused access switch 1 sends a channel add message to the access network 1, notifying that the operation of the added channel is completed.

Step 509: The fused access switch 1 sends a channel addition message to the service server, indicating that the increased channel operation required by the service server is completed.

Here, the channel addition message carries the access location information of the terminal corresponding to the newly added traffic channel identifier.

When the newly added traffic channel has different radio access technologies from the established traffic channel, that is, the service channel is established with the access network 2, but when the access network 2 is connected to the converged access switch 1, new services are implemented. In the case of the channel, in step 506, the establishment of the new traffic channel is completed, and the establishment of the new access and the new traffic channel is reported to the converged access switch 1 through the access network 2; in step 507, the converged access switch is established. 1 Update the information of the converged terminal.

When the newly added traffic channel has the same radio access technology as the established traffic channel, namely: When the service channel is established with the access network 1, when the new service channel is implemented, in step 506, the establishment of the new service channel is completed, and the new access and report is reported to the converged access switch 1 through the access network 1. The establishment of the new traffic channel; in step 507, the converged access switch 1 updates the information of the converged terminal, and does not need to perform step 508.

As can be seen from the above description, in the present invention, the selection of the access technology may be dynamic, that is, the access may be determined according to the different services applied by the user and the specific conditions of the network resources at the time of application. technology. During the progress of the service, as the network status changes, the service progresses, and the terminal location is updated, the access technology used may also be adjusted accordingly. The selection of access technologies is transparent to users and networks.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
