Description

Method, device and system for interconnecting broadband wireless access network and digital subscriber line network

technical field

The invention relates to the communication field, in particular to a method, device and system for interconnecting a broadband wireless access network and a digital subscriber line network.

Background technique

Broadband wireless access BWA (Broadband wireless access, broadband wireless access) equipment can provide users with convenient broadband access methods. Currently, there are broadband wireless access devices based on proprietary protocols and broadband wireless access devices based on standard protocols. The broadband wireless access equipment defined by the IEEE (Institute of Electrical and Electronics Engineers) 802.16 standard is a subset of a series of standards for broadband wireless access technologies. BWA equipment includes WIMAX (Worldwide Interactive Microwave Access) equipment.

The architecture of the DSL (Digital Subscriber Line) network is evolving from PPP over ATM (ATM bearer point-to-point protocol) to an IP QoS (Quality of Service) enabled architecture based on Ethernet Aggregation and connectivity (Ethernet aggregation and connectivity). A general structural diagram of the enabling architecture is shown in FIG. 1 . In Fig. 1, the protocol stacks of three modes of PPPoE (PPP protocol carried over Ethernet), IPoE (IP protocol carried over Ethernet) and IP based (based on IP) of the enabled architecture are respectively given.

In Figure 1, T is the reference point between TE (terminal equipment) and DSLModem (DSL modem) in the CPN (Customer Premises Network) network; U is the DSL Modem and access point DSLAM (Digital Subscriber Line Access Multiplexer) V is the reference point of Ethernet Aggregation between the DSLAM and BRAS (Broadband Access Server) in the Access Network (access network); A10 is the reference point between the access network and the SP (service provider) A reference point, which can connect an ASP (Application Service Provider) to an NSP (Network Service Provider) owning an access network, or connect an NSP to a visited access network in a roaming scenario. The DSL access technology is used for interconnection between the CPN network and the access network.

In PPPoE mode, only Ethernet bridging technology can be used between BRAS and TE. This mode uses PPP over Ethernet as the link protocol to provide terminal configuration and connection control and management capabilities. This mode is suitable for pure data services.

In IPoE mode, only Ethernet bridging technology can be used between BRAS and TE. This mode allows QoSProvisioning (QoS provisioning) and completely relies on DHCP (Dynamic Host Configuration Protocol) to provide identification and configuration capabilities for TE. This mode is mainly suitable for triple play (providing data + voice + video) services.

In IP based mode, IP layer 3 routing technology must be used between BRAS and TE. This mode allows IPQoS to be issued to BRAS and DSL Modem, completely relies on DHCP to provide identification and configuration for TE, and completes appropriate routing settings in the DHCP discovery (DHCP discovery) stage. This mode is mainly applicable to Triple play (providing data + voice + video) business.

IEEE 802.16 is the first broadband wireless access standard. There are two main versions of this standard: "802.16-2004", which is the broadband fixed wireless access version of the 802.16 standard. "802.16e", that is, the broadband mobile wireless access version of the 802.16 standard. Among them, 802.16-2004 only defines two types of network elements: BS (base station) and SS (subscriber station). BS and SS are interconnected by broadband fixed wireless access technology; and MS (Mobile Subscriber Station), BS and MS are interconnected using broadband mobile wireless access technology.

On the basis of 802.16, the WiMAX Forum defines ASN (Access Service Network) and CSN (Connection Service Network), which constitute a broadband WiMAX network to support fixed, nomadic, portable, simple IP mobile or full mobile access. Taking 802.16e as an example, the schematic diagram of the reference architecture of the WIMAX network is shown in Figure 2 .

In Fig. 2, R1 is the reference point between MS/SS and ASN, R3 is the reference point between ASN and CSN; T is the reference point between TE and MS/SS in the CPN network. The MS can be a simple MobileTerminal (mobile terminal), or a TE can be connected under the MS. The protocol stacks when the MS is a simple mobile terminal and when the TE is attached to the MS are respectively shown below in Fig. 2 .

The WIMAX 802.16e mobile network adopts a two-layer mobile management architecture. Unlike the DSL network that uses the PPP protocol, the WIMAX 802.16e mobile network uses the 802.16 security sublayer PKMv2 (private key management version 2) and DHCP to provide terminal configuration and link control and management capabilities. In mobile application, WIMAX802.16e mobile network adopts three-layer mobile management based on MIP (Mobile IP) between ASN and CSN.

In the prior art, an interconnection solution between WiMAX and DSL is: interconnecting WiMAX and DSL at a reference point V in the access network. The specific connection method is shown in Figure 3 and Figure 4.

The disadvantages of this connection scheme are:

1. The coupling between WiMAX and DSL is loose, and the resources of the original DSL network (such as DSL cables and DSLAM) have not been fully utilized;

2. When the number of WiMAX base stations or ASNs is large, BRAS will become a bottleneck, and the interconnection of WiMAX and DSL at the reference point V will restrict the scalability of the network to a certain extent.

In the prior art, another interconnection solution between WiMAX and DSL is: interconnect WiMAX and DSL in the core network. The specific connection method is shown in Figure 5.

The disadvantages of this connection scheme are:

1. The coupling between WiMAX and DSL is the loosest, and the resources of the original DSL network (such as DSL cables, DSLAM and BRAS) have not been fully utilized;

Detailed ways

The present invention provides a method, device and system for interconnecting a broadband wireless access network and a digital subscriber line network. The core of the present invention is: when the BS or ASN includes a DSL Modem function, the WiMAX network and the DSL network are referenced Interconnect at point U. When the BS or ASN does not include the DSLModem function, add a DSL Modem to the DSL network, and interconnect the WiMAX network and the DSL network at the reference point U through the DSL Modem.

The method for interconnecting the WiMAX network and the DSL network described in the present invention is first described below. When the BS of WiMAX includes the DSL Modem function, the schematic diagram of the interconnection scheme between WiMAX 802.16-2004 and DSL at the reference point U in the present invention is shown in Figure 6 The specific description is as follows:

The WiMAX 802.16-2004 BS and DSL are interconnected at the reference point U. This solution has four modes: PPPoE mode 1, PPPoE mode 2, IPoE mode and IP based mode. Figure 6 shows the TE ->SS->BS->DSLAM->BRAS->SP (ASP or NSP) protocol stack under the path. This path is the end-to-end path for WiMAX 802.16-2004 to access the DSL network at the DSL reference point U. This interconnection scheme is mainly suitable for fixed access applications. The four modes of the program are described below:

1. PPPoE mode 1.

Under the path of TE->SS->BS->DSLAM->BRAS->SP, only Layer 2 bridging technology can be used between BRAS and TE, for example, Ethernet bridging technology, and the use of Layer 2 bridging technology refers to BS, SS and DSLAM all serve as Layer 2 network elements. Under Layer 2 bridging, this mode can use 802.16-2004 Layer 2 wireless access technology between BS and SS to replace DSL Layer 2 wired access, or as a Layer 2 wireless extension of DSL Layer 2 wired access. The 802.16-2004 Layer 2 wireless access technology can support ETH CS on the air interface, thereby avoiding the impact on the high-level network architecture. In order to support the whole service (wholesale business), the recommendation of the DSL forum can be continued, the PPP protocol is used as the address allocation and authentication mechanism between the TE and the SP, and the PPP over Ethernet is supported as the link protocol between the BRAS and the TE, providing terminal configuration and Connected control and management capabilities. This mode is suitable for pure data services.

2. PPPoE mode 2.

In addition to all the features of the above-mentioned PPPoE mode 1, this mode adopts a tunnel protocol between the network operator's BRAS and the SP, such as L2TP (Layer 2 Tunneling Protocol) protocol or MPLS (Multiprotocol Label Switching) tunnel. The role of the tunnel protocol here is to distinguish different service providers SP.

3. IPoE mode.

Under the path of TE->SS->BS->DSLAM->BRAS->SP, only Layer 2 bridging technology can be used between BRAS and TE, for example, Ethernet bridging technology, and the use of Layer 2 bridging technology refers to BS, SS, and DSLAM are all Layer 2 network elements. Under Layer 2 bridging, this mode can use 802.16-2004 Layer 2 wireless access technology between BS and SS to replace DSL Layer 2 wired access, or as a Layer 2 wireless extension of DSL Layer 2 wired access, the 802.16- 2004 Layer 2 wireless access technology can support IP CS (IP Convergence Sublayer) on the air interface, thereby avoiding the impact on the high-level network architecture. This mode allows QoS Provisioning (QoS provisioning), which completely relies on DHCP to provide identification and configuration capabilities for TE. This mode is mainly suitable for Triple play (providing data + voice + video) services.

4. IP based mode.

Under the TE->SS->BS->DSLAM->BRAS->SP path, three-layer routing technology must be used between BRAS and TE, for example, IP three-layer routing, and the above-mentioned three-layer routing technology refers to BS , SS and DSLAM are all Layer 3 network elements. Under the three-layer routing, this mode can run on the 802.16-2004 layer two wireless access technology at the IP layer between BS and SS, replacing DSL wired access or as a wireless extension of DSL wired access. This mode must adopt IP three-layer routing technology between BRAS and TE, allowing QoS Provisioning (QoS provisioning), completely depends on DHCP to provide identification and configuration capabilities for TE, and complete appropriate routing settings in the DHCP discovery (DHCP discovery) stage. This mode is mainly applicable to Triple play (providing data + voice + video) business.

When the DSL Modem function is included in the ASN, the schematic diagram of the interconnection scheme between WiMAX 802.16e and DSL at the reference point U in the present invention is shown in Figure 7, and the specific description is as follows:

Interconnect the ASN and DSL of WiMAX 802.16e at the reference point U. This solution has 5 modes: PPPoE mode 1, PPPoE mode 2, PPPoE mode 3, IP based mode 1 and IP based mode 2, respectively. The protocol stacks of various modes under the path of TE->MS->ASN->DSLAM->BRAS->SP (ASP or NSP) are given. This path is the end-to-end path for WiMAX 802.16e to access the DSL network at the DSL reference point U. This interconnection scheme is mainly suitable for fixed and nomadic access applications, and can also support portable and mobile access applications to a certain extent. The following are the five modes of the program:

1. PPPoE mode 1.

Under the path of TE->MS->ASN->DSLAM->BRAS->SP, only Layer 2 bridging technology can be used between BRAS and TE, for example, Ethernet bridging. The above mentioned Layer 2 bridging technology refers to ASN All NEs and DSLAMs in are Layer 2 NEs. Under Layer 2 bridging, this mode can use 802.16e Layer 2 wireless access technology between ASN and MS to replace DSL Layer 2 wired access, or as a Layer 2 wireless extension of DSL Layer 2 wired access. Layer wireless access technology can support ETH CS on the air interface, avoiding the impact on the high-level network architecture. In order to support the whole service (wholesale business), the recommendation of the DSL forum can be continued. PPP is used as the address allocation and authentication mechanism between TE and SP, and PPP over Ethernet is supported as the link protocol between BRAS and TE to provide terminal configuration and connection. control and management capabilities. This mode extends the functions of 802.16e wireless resource management, load balancing and security features. It is mainly suitable for fixed and nomadic pure data service access applications.

2. PPPoE mode 2.

In addition to having all the features of the above-mentioned PPPoE mode 1, a tunnel protocol, such as L2TP protocol or MPLS tunnel, is used between the BRAS of the network operator and the SP of the service operator. The role of the tunnel protocol here is to distinguish different service providers SP.

3. IPoE mode3.
