Description

Method, system and device for fixed mobile convergence

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a method, system, and apparatus for a Fixed Mobile Convergence (FMC). Background technique

WiMAX (Worldwide Interoperability for Microwave Access) is a wireless metropolitan area network technology based on the IEEE 802.16 standard. The WiMAX network is mainly composed of three parts, namely, a mobile terminal (MS, Mobile Station), an Access Service Network (ASN), and a Connectivity Service Network (CSN). The access service network ASN includes a base station (BS, Base Station) and an access service network gateway (ASN GW, Access Service Network Gateway). Connection Service Network The CSN includes logical entities such as Policy Server (PF), Authentication, Authorization and Accounting Server (AAA Server), Application Server (AF), and so on. The wireless side of the WiMAX network (R1 interface) is a wireless metropolitan area network access technology based on the IEEE 802.16d/e standard. WiMAX's existing network reference model is shown in Figure 1.

The mobile terminal MS: directly faces the WiMAX air interface, and has a mobile terminal device capable of accessing the WiMAX network.

Access Service Network ASN: WiMAX Terminal MS provides a network function set for wireless access services. The ASN includes two network elements, a base station BS and an access service network gateway ASN GW. The two network elements can be two separate physical entities or they can be located in the same physical entity. The main functions provided are as follows:

Provides physical layer and link layer connection with MS; provides network discovery and selection; access authentication, authorization agent; radio resource control and management; billing statistics and billing record generation; air interface link switching; paging and Location management; proxy mobile IP (Internet Protocol) function; QoS (Quality of Service) authorization and bearer control of service flow; air interface data compression and encryption. The functions listed above are performed by various functional entities serving the MS. As the terminal moves and the network resources are optimized, each functional entity can be distributed in different ASNs. Therefore, when providing services to a terminal, multiple ASN interactions may be involved.

Connection Service Network CSN: WiMAX Terminal MS provides a network function set for network connection services. The main features provided are as follows:

User subscription information management; access authentication, authorization control; IP address allocation and management; billing service and user bill management; IP mobility management; provision of roaming services; provision of location-based services; provision of multicast broadcast services; IP Multimedia Subsystem business and more.

The DSL (Digital Subscriber Loop) system is one of the main systems for fixed-line broadband access. The network reference model is shown in Figure 2. DSL is currently the fastest growing high-speed broadband Internet access technology in the world, including HDSL, SDSL, VDSL, ADSL, etc., commonly referred to as XDSL. Their main differences are reflected in the difference in signal transmission speed and distance and the difference in symmetry between the uplink rate and the downlink rate. The DSL features a common copper telephone line as the transmission medium, which is widely implemented and protects the original investment. As a broadband network connection technology, its network connection speed is fascinating. The ADSL upload rate is 604 ~ 1Mbps, and the downlink rate is up to 8Mbps, which is 150 times that of the ordinary 56K modem. In addition, when using ADSL, since voice and data are transmitted separately, the Internet does not affect the normal use of the phone. Internet access without ADSL is not required to pay for additional telephone charges, and it is always online.

Step S1: The proxy interconnection function entity acquires user access information of the digital subscriber line DSL, and the proxy interconnection function entity is an entity that the proxy network user accesses the DSL.

For example, in the embodiment of the present invention, the proxy interconnection function entity is an entity that proxyes global access to the microwave interoperability WiMAX network user to access the DSL.

The proxy interconnection function entity combines an ASN network entity (for example, a base station BS and a gateway GW) or a CSN network entity (for example, a home agent HA) to implement maintenance user information, instead of the user and the DSL. The role of the network in establishing, maintaining, and tearing down PPP sessions.

Before the step, the network user (for example, a user of the WiMAX network) sends a user access authentication request (including user access authentication or mobile IP registration authentication) to the home authentication authentication accounting server AAA; The AAA sends user access information of the network user to the proxy function entity.

The user access information includes: a user authentication message, and/or a link parameter. The user authentication message further includes: DSL network information, DSL home carrier domain name, L2TP network server address, point-to-point protocol authentication mode and link parameters, link control protocol parameters, and/or user name, and/or password. And/or user network layer protocol information, and/or the user's MAC address, and/or the user's MIP key, and/or home agent HA address, and the like.

Step S2: The proxy interconnection function entity establishes a point-to-point session with the DSL mobile access server according to the user access information; and maintains or releases the peer-to-peer session.

In this step, the DSL mobile access server is a broadband access server BRAS, and/or a second layer tunneling protocol L2TP network server. When the DSL mobile access server is a BRAS, the proxy interconnection function entity establishes a point-to-point session with the DSL access server according to the user access information; before establishing the point-to-point session, the method further includes: receiving, according to the user The MAC information in the incoming information initiates an Ethernet Point-to-Point Protocol PPPoE session; and maintains or releases the Ethernet Point-to-Point Protocol PPPoE session. When the DSL mobile access server is a L2TP network server, a point-to-point meeting is established. The method further includes: establishing an L2TP tunnel and/or a session according to the L2TP network server address information in the user access information; and maintaining or releasing the L2TP tunnel session.

The proxy interconnection function entity establishes a point-to-point session with the DSL access server according to the user access information; and the maintaining or releasing the peer-to-peer session specifically includes: according to the DSL access information in the user access information DSL network information, DSL home carrier domain name, link control protocol parameters, and/or username, and/or password, and/or user network layer protocol information establish a point-to-point session; and maintain or release the point Go to the point session.

In the above steps, the method further includes: the access service network gateway sends a mobile IP registration message, where the mobile IP registration message carries the terminal physical address MAC; the proxy interconnection function entity receives the registration request message, and obtains an IP registration related key. Information, performing mobile IP registration according to the MAC and the IP registration related key information. The proxy interconnect function entity obtains the assigned IP address/and or network prefix information from the DSL network through the network control protocol NCP.

The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.

The first embodiment of the present invention provides a method for fixed mobile convergence FMC. The ASN network replaces the terminal to establish a PPP session, so that the PPP protocol terminal cannot access the DSL network. The need for the terminal is reduced, and the terminal can simultaneously enjoy the services provided by the fixed network and the wireless system. In this embodiment, the wireless network directly connects to the core network of the DSL network through the ASN network, enjoys the existing fixed network service, and provides link layer support of the wireless network.

The network reference model and protocol stack structure are shown in Figure 3. The fixed mobile convergence system includes the following entities:

Terminal equipment TE: IP-based user terminal equipment;

Mobile terminal MS: A wireless device with wireless air interface access capability, through which the terminal device TE accesses the wireless network. The MS can be integrated on the TE, such as a PCMCIA card, a wireless network card, etc., and plugged into a general-purpose PC or a notebook;

Base station BS and gateway GW: ASN network entity, providing wireless for mobile terminal MS Access service function; in this embodiment, it is also a physical entity where the TW network interconnection function entity IWU (Interworking Unit) is located;

Interconnect Functional Entity IWU: The main functional entity of the wireless system and the fixed network interconnection. In this embodiment, the IWU is located in the ASN GW. The functional requirements are as follows:

Maintain user information, including DSL network information, DSL home carrier domain name, L2TP network server address, point-to-point protocol authentication mode and link parameters, link control protocol parameters, and/or username, and/or password, and / or user network layer protocol information, and / or the user's MAC address, and / or the user's MIP key, and / or home agent HA address. These user information can be configured on the IWU or downloaded from the AAA; instead of the user establishing, maintaining, and tearing down the PPP session with the DSL network. When accessing the DSL network, the user authentication information is negotiated according to the user information, the network layer protocol type is negotiated, and the user authentication, authentication, and authentication authentication are used to replace the authentication of the fixed network access. ; When exiting the DSL network, remove the corresponding user PPP session.

The IWU entity in this embodiment is a logical function entity, which may be located in a physical entity such as an ASN GW or a BS in the ASN network, and is not enumerated here.

The specific user access DSL process and exit DSL process are shown in Figure 4, including the following steps:

Step S401: The TE/MS initiates an access authentication process in the network, and accesses the network in the network. The user is a network user. The TE/MS only needs to support the IPCS (IP Convergence Sublayer) capability. In order for the user to access the DSL network, the user's DSL access information is configured on the network side.

For example, in the embodiment of the present invention, the access authentication process may be initiated in the WiMAX network. The user is a WiMAX network user.

Step S402: After the home AAA successfully authenticates the TE/MS, the home AAA returns an authentication response to the Authenticator corresponding to the TE/MS, and the Authenticator can be located in the ASN GW or the ASN. The functional entities of the BS and the ASN GW are described in the following example. In the delivered Access Accept message, the DSL corresponding to the user is carried at the same time. Access information, including DSL network information, DSL home carrier domain name, L2TP network server address, point-to-point protocol authentication mode and link parameters, link control protocol parameters (including maximum receiving unit, authentication protocol, quality of service agreement, Magic word. Protocol domain compression and address control domain compression parameters, user name, password, user network layer protocol type, user's MAC address, user's MIP (mobile IP) related key, HA address, etc.

Step S403, after receiving the above message, the ASN GW selects the BRAS corresponding to the DSL network according to the DSL network information or the default configuration of the GW, and uses the obtained username and password instead of the user to establish a PPP connection with the BRAS, the PPP connection. Can be carried on top of PPPoE.

If the mobility in the CSN range is required, the ASN GW can obtain the mobile IP registration from the user's HA by using the MIP related key obtained in step S402 from the user's MAC authentication process. In the event of an Anchor DPF migration, the above information is accompanied by a terminal context migration for the MIP update process.

If the IP address of the user is required to be allocated in the DSL network, the ASN GW obtains the IP address assigned by the DSL network to the user through the NCP (Network Control Protocol) process defined by the PPP-related protocol.

Step S404, the ASN GW triggers a pre-established flow establishment process of the user, and the pre-made flow information is from the AAA or configured in the ASN GW. This step and the above step S403 are two branches that establish a connection, and there is no clear sequence relationship.

Step S405: The TE/MS obtains the IP address of the terminal through the DHCP process. If the IP address of the user is required to be allocated in the DSL network, the ASN GW acts as the DHCP proxy, and the address obtained in step S403 is allocated to the user; if the IP of the TE/MS If the address is allocated on the WiMAX network, the IP address acquisition process defined in the existing protocol is used, and details are not described herein.

The TE/MS uses the obtained IP address to communicate with the DSL network for data communication and enjoys the DSL service. If the IP is allocated on the WiMAX network, the BRAS is required to perform the NAT (Network Address Translation) function.

In step S406, when the TE/MS wants to exit the network, the TE/MS exit process is triggered. For specific procedures, refer to existing standards, and details are not described herein.

Step S407, detecting that the TE/MS is disconnected from the network, triggering the ASN GW to release the PPP connection with the DSL network. If the registration of the MIP is performed in step S403, the deregistration process of the MIP is required here.

The first embodiment of the present invention directly connects to the core network of the DSL network through the wireless network ASN, establishes a PPP connection, and enjoys the DSL service, wherein the proxy interconnection function entity is through the interconnection functional entity IWU and the ASN network entity (base station BS and gateway GW) Combined with the function extension to achieve its logic function. The fixed network users can enjoy the mobility management services unique to the wireless system, and the wireless system enjoys the existing fixed network resources and services, and enables the terminals without the PPP protocol to access the existing DSL network.

In the second embodiment of the present invention, a method for fixed mobile convergence FMC, the wireless network directly connects to the core network of the DSL network through the CSN network, enjoys the existing fixed network service, and provides the link layer and IP layer mobility of the wireless network. stand by.

The network reference model and protocol stack structure are shown in Figure 5: The following entities are included: Terminal Equipment TE: IP-based user terminal equipment;

Base station BS and gateway GW: ASN network entity, providing wireless access service function for mobile terminal MS;

Home agent HA: The CSN network entity provides the home agent function of mobile IP. In this embodiment, the physical entity of the DSL network interconnection function entity IWU is also located; the interconnection function entity IWU: the main functional entity of the wireless system and the fixed network interconnection. In this embodiment, the IWU is located in the HA, and its functional requirements are as follows: Shown as follows:

Maintain user information, including DSL network information, DSL home carrier domain name, L2TP network server address, point-to-point protocol authentication mode and link parameters, link control protocol parameters, and/or username, and/or password, and / or user network layer protocol information, and / or the user's MAC address, and / or the user's MIP key, and / or home agent HA address. These user information can be configured in IWU or downloaded from AAA; Instead of establishing, maintaining, and tearing down PPP sessions with users and DSL networks. When accessing the DSL network, the user authentication is used to negotiate authentication and authentication, and the network layer protocol type is negotiated. And replacing the user's authentication authentication of the fixed network access according to the user name, the password, and the negotiated authentication method in the user information; when exiting the DSL network, the corresponding user PPP session is removed;

Establish, maintain, and tear down the L2TP tunnel based on the LNS address in the user information and the LNS. Before the user establishes a PPP session, an L2TP tunnel is established with the LNS according to the LNS address in the user information. An L2TP tunnel may be established based on a PPP session or an I2U-based session. In the L2TP tunnel, different L2TP session identifiers need to be established for different PPP sessions. When the user exits the DSL network, the corresponding L2TP session and/or L2TP tunnel is deleted.

L2TP network server: The NSP network of the network service provider of the DSL system provides L2TP tunnel establishment and maintenance functions for carrying and protecting user PPP sessions.

According to the above interconnection network architecture, the terminal access network process is as shown in FIG. 6:

Step S601: The mobile terminal performs an initial network access authentication and registration process.

Step S602: After the authentication is successful, the authenticator gateway initiates initial service flow establishment and optional preset service flow establishment.

Step S603: The access service network gateway initiates the mobile IP registration MIP instead of the terminal, and the optional mobile IP registration may also be initiated by the mobile terminal MS or the terminal device TE itself, and the mobile IP registration message carries the terminal physical address MAC.

Step S604: After receiving the mobile IP registration message, the mobile IP home agent initiates an authentication process to the home authentication authentication accounting server to obtain key information related to the mobile IP registration, and in the process, the home authentication authentication accounting server passes the authentication. The right authentication response message access-accept delivers a user authentication message and/or link parameters required to establish a PPP connection instead of the user.

Step S605: After the home agent HA successfully obtains the DSL access parameter of the user, initiates the establishment of the L2TP session of the Layer 2 tunneling protocol. If the L2TP tunnel has not been established before, the L2TP tunnel is established first.

Step S606, after the successful establishment of the L2TP session, the HA is authenticated according to the slave. The ppp establishment parameter obtained by the authentication and accounting server is used by the proxy terminal device to initiate the establishment of the PPP session. The HA obtains an IP address or a network prefix allocated to the terminal device from the DSL network during the PPP session establishment process.

Step S607: The HA replies to the mobile IP registration response message. When the registration is successful, the HA carries the IP address or network prefix assigned to the terminal device in the registration response message. When the network side initiates mobile IP registration instead of the terminal, the IP address or network prefix of the terminal device delivered by the HA is stored in the ASN GW.

Step S608: If the network side replaces the mobile IP registration initiated by the terminal device, the terminal device also needs to initiate an IP acquisition process, such as DHCP, the router requests the RS, and the like, and obtains the IP address or network prefix delivered by the HA from the network side.

The interconnected functional entity IWU enumerated in the above embodiment is located in the home agent HA. In actual use, it can also be located in the core network functional entity such as the packet data network gateway PDN-GW, the core router CR, the border data gateway BGF, etc. - Narrative.

The second embodiment of the present invention has the same function as that of the first embodiment, that is, the fixed network user can enjoy the mobility management service unique to the wireless system, and the wireless system enjoys the existing fixed network network resources and services, and does not have the PPP protocol. The terminal can access the existing DSL network. The difference between the two embodiments is that the wireless network CSN directly connects to the core network of the DSL network (the network service provider NSP of the DSL system), establishes a PPP connection, and enjoys the DSL service, wherein the proxy interconnection function entity is interconnected. The functional entity IWU and the CSN network entity (home agent HA) are combined to perform functional expansion to implement their logical functions, including establishing, maintaining, and releasing L2TP sessions.

In the third embodiment of the present invention, a method for fixed mobile convergence FMC, the wireless network connects to the broadband access server BRAS of the DSL network through the CSN network, accesses the DSL core network through the BRAS, and provides the link layer and the IP layer of the wireless network. Mobility support.

The network reference model and the protocol stack structure are shown in Figure 7. Because the BRAS to access the DSL is different from the second embodiment, the requirements of the IWU are different. In addition to the L2TP tunnel, the IWU needs to complete the function. : Establish, maintain, and tear down PPPoE sessions based on the MAC address of the terminal device instead of the user. Before the PPP session is established instead of the user, a PPPoE session is established with the BRAS according to the MAC address in the user information. use When the user exits the DSL network, the PPPoE session is removed instead of the user. The rest is the same as the first embodiment, and will not be described again.

According to the foregoing interconnection network architecture, the terminal access network process is as shown in FIG. 8, and includes the following steps:

Steps S801~S804 are the same as steps S601~S604.

Step S805: The HA initiates a PPPoE session establishment process by using the physical address of the terminal device acquired in the MIP registration process.

Step S806: After successfully establishing the PPPoE session, the HA initiates the establishment of the PPP session according to the PPP establishment parameter proxy terminal device obtained from the home authentication authentication accounting server. The HA obtains the IP address or network prefix assigned to the terminal device from the DSL network during the establishment of the PPP session.

Steps S807~S808 are the same as steps S607~S608.

The difference between the embodiment and the second embodiment is that the HA in this embodiment is connected to the broadband remote access server BRAS on the data plane. In this case, the connection between the HA and the BRAS is required to be based on Ethernet. even. In order to access the DSL system in place of the terminal device, the HA must emulate the terminal access at the Ethernet layer, that is, to perform MAC address spoofing, and use the MAC address of the terminal device to communicate with the BRAS.

The IWU entity in this embodiment is a logical function entity, which may be located in a physical entity such as a home agent HA, a core router CR, a border gateway BGF, a packet data network gateway PDN-GW in the CSN network, and is not enumerated here.

The third embodiment of the present invention has the same functions as the first embodiment and the second embodiment, that is, the fixed network user can enjoy the mobility management service unique to the wireless system, and the wireless system enjoys the existing fixed network network resources and services, and makes A terminal that does not have a PPP protocol can access an existing DSL network. The difference is that the third embodiment is to access the DSL core network through the broadband access device BRAS connected to the DSL network, establish a PPP connection, and enjoy the DSL service, wherein the proxy interconnection function entity is through the interconnection functional entity IWU and CSN network. The entity (home agent HA) combines function expansion to implement its logical function. The difference from the second embodiment is that the PPPoE session is established, maintained, and released to replace the L2TP session. In the foregoing embodiment 2 and the third embodiment, the PPP session is established by using the CSN network instead of the terminal, so that the terminal that does not support the PPP protocol can access the DSL network. The need for the terminal is reduced, and the terminal can enjoy the services provided by the fixed network and the wireless system at the same time.
