Description

Method and system for interconnection between broadband wireless access network and multi-service operator network

technical field

The invention relates to the communication field, in particular to a method and system for interconnecting a broadband wireless access network and an MSO (Multi-Service Operator) network. the

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

The rapid development of digital technology makes the three business networks of computer network, public telecommunication network and cable television network begin to penetrate each other. HFC (fiber optic/coaxial cable hybrid network) has become one of the three-network service carriers that has attracted much attention in the industry because of its good frequency band resources, coverage and service integration capabilities. DOCSIS (HFC access network) is a two-way interactive broadband network based on the cable TV coaxial network. It retains the traditional analog transmission mode and makes full use of the existing cable TV coaxial cable resources without re-laying The distribution network can provide users with various services such as telephone, radio and television, video on demand, Internet access, video conferencing, and data. Therefore, DOCSIS has the characteristics of low cost, wide frequency band and multi-service, and it will become the preferred solution to solve the last 1 km broadband access. PacketCable (packet cable) standard is an MSO broadband network standard based on DOCSIS. the

PacketCable is divided into HFC access network, customer premises network and Managed IP Network (management IP network). The schematic diagram of PacketCable reference architecture based on HFC access network is shown in Figure 1, and the network elements in Managed IP Network are omitted in Figure 1. The main network elements of the HFC access network and customer premises network include: CMTS (cable modem central office equipment), HFC/CableNetwork (HFC transmission network), CM (Cable Modem, cable modem), multimedia terminal adapter MTA (Multimedia Terminal Adapter, omitted in the figure), etc. Among them, CMCI is the reference point of CPE (customer equipment) and CM in the customer premises network; CMRFI is the reference point between CM and HFC/Cable Network; CMTS-NSI is the Ethernet Aggregation between CMTS and Managed IPNetwork (Ethernet aggregation) reference point. the

Between MANAGED IP NETWORK and CPE, only Layer 2 network bridging technology can be used; IP Layer 3 routing technology can also be used. the

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. the

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 . the

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

The WIMAX 802.16e mobile network adopts a two-layer mobile management architecture, and adopts 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, WIMAX 802.16e mobile network adopts three-layer mobile management based on MIP (Mobile IP) between ASN and CSN. the

IP Layer 3 routing technology can be used between the ASN egress node and the MS, and IP CS (IP Convergence Sublayer) can be used on the air interface; Layer 2 network bridging technology can also be used between the ASN egress node and the MS, such as Ethernet bridging, on the air interface Support ETH CS (Ethernet Convergence Sublayer)

The method for interconnecting the WiMAX network and the MSO broadband network according to the present invention will be described first. This method includes 2 options. the

Scheme 1, the schematic diagram of the interconnection scheme between WiMAX 802.16-2004 and MSO broadband network at the reference point CMTS-NSI in the present invention is shown in Figure 3, and the specific description is as follows:

This interconnection scheme belongs to the loose coupling scheme. There are two modes in this scheme. Figure 3 shows the protocol stacks of various modes under the path of TE->SS->BS->MANAGED IP NETWORK. This path is the end-to-end path for WiMAX 802.16-2004 to access the MSO network at the MSO reference point CMTS-NSI. This interconnection solution is mainly suitable for fixed access applications, and supports unified billing, unified customer care (Customer Care) and unified authentication. The following are the two modes of the program:

All network elements and MSs are Layer 2 network elements. The 802.16e Layer 2 wireless access technology is used between the BS and MS to replace DOCSIS Layer 2 wired access, or as a Layer 2 wireless extension of DOCSIS Layer 2 wired access. 802.16e Layer 2 wireless access technology (such as Ethernet bridging technology) can support ETH CS on the air interface. the

2. Mode 2

Under the path of TE->MS->BS->ASN->MANAGED IP NETWORK, a three-layer routing technology is used between the MANAGED IP NETWORK and TE, for example, IP three-layer routing technology, and the above-mentioned three-layer routing technology refers to All network elements and MS of ASN are three-layer network elements, running 802.16e two-layer wireless access technology on the IP layer between BS and MS, replacing DOCSIS wired access or as a wireless extension of DOCSIS wired access, The 802.16e Layer 2 wireless access technology can support IP CS on the air interface. the

3. Mode 3

Under the path of MS->BS->ASN->MANAGED IP NETWORK, use three-layer routing technology between MANAGEDIP NETWORK and MS, for example, IP three-layer routing technology, the above-mentioned adopting three-layer routing technology refers to all network elements of ASN Both BS and MS are Layer 3 network elements, running 802.16e Layer 2 wireless access technology on the IP layer between BS and MS, replacing DOCSIS wired access or as a wireless extension of DOCSIS wired access, the 802.16e 2 Layer wireless access technology can support IP CS on the air interface. the

In terms of security, the above three modes continue to use the 802.16 security sublayer PKMv2 security architecture between MS and BS, and continue to use the DOCSIS security sublayer security architecture between ASN and CMTS. the
