Problems solved by technology

The disadvantage of this method is: for the many-to-many networking of BS and ASN-GW, the configuration will be more complicated, and when the network composition changes, the configuration of many network entities needs to be modified. Once the configuration is modified incorrectly, it will cause Failed to switch process
The disadvantage of this method is: since the BS ID is specified in the protocol as a 48-bit binary number, there may not be enough space in the BS ID to add ASN-GW information, especially for the many-to-many networking of BS and ASN-GW
Therefore, its application is limited

Embodiment Construction

[0028] The present invention will be further elaborated below according to the drawings and specific embodiments.

[0029] Firstly, introduce the process of the service gateway locating the target gateway in R4 interface switching, as shown in Figure 5 Shown:

[0030] Step S11, the serving base station forwards to the serving gateway after receiving a handover request message initiated by a relevant entity on the network side or the mobile subscriber station (MSS) side, and the message includes the identification information of the target base station;

[0031] Step S12, the service gateway obtains the identification of the target base station after receiving the handover request message, and generates a domain name according to certain rules, and sends the domain name to a domain name server (DNS); it should be noted that there are many ways to generate a domain name Type, as long as the domain name generated by the gateway (ASN-GW) using a prescribed method is correctly co...

Abstract

The present invention relates to WiMAX accessing service network technique, especially relating to WiMAX accessing service network gateway mutually positional method. It contains Said ASN-GW generating domain name, transmitting said domain name domain name Server domain name server; said domain name server feeding back corresponded gateway IP address to said ASN-GW; ASN-GW according to said gateway IP address positioning target gateway, transmitting said switch request or conversation request. The present invention adopts domain name resolving mode to solve WiMAX accessing service network gateway mutually positional problem; when network composing generating variation, only needing modifying domain name configuration in DNS server without modifying each network solid configuration.

Description

[technical field] [0001] The invention relates to WiMAX access service network technology, in particular to a method for mutual positioning between gateways of the WiMAX access service network. [Background technique] [0002] With the vigorous development of Internet services and the wide application of wireless networks, the WiMAX system has received a lot of applications and attention due to its good wireless access characteristics. How the WiMAX system is applied to mobile users, and how to better provide the forwarding or routing function of packet services between the network and mobile users has become a new focus of research in the industry. [0003] WiMAX network architecture system such as figure 1 shown. Among them, ASN (Access Service Network) is defined as a set of network functions that provide wireless access services for WiMAX terminals, and ASN includes base station (BS) and access service network gateway (ASN-GW) network elements. CSN (Connection Service ...
