Problems solved by technology

[0020] The disadvantage is that the DHCP protocol can only support automatic configuration on the Ethernet medium at present, and cannot support configuration acquisition on serial links such as PPP, and cannot be used on links such as E1 / T1
In the 3G RAN network, E1 / T1 is a very common transmission path, which leads to a relatively large restriction on the use of DHCP in the RAN network

Embodiment approach 1

[0092] Like the first embodiment, this embodiment has no specific requirements on the upper and lower devices. As an example, the upper device can be a base station controller, the lower device can be a base station, and the configuration information can be the configuration information required by the maintenance channel of the base station .

[0093] As shown in FIG. 5 , the upper-level device and the lower-level device first perform LCP layer negotiation. After the LCP layer negotiation is completed, the IPCP layer negotiation is performed. When negotiating at the IPCP layer, the upper-level device carries the configuration information in at least one predetermined negotiation parameter of the IPCP message and transmits it to the lower-level device.

[0094] The IPCP layer negotiation specifically includes the following steps:

[0095] The lower-level device sends a negotiation initiation message to the upper-level device;

[0096] After receiving the negotiation initiatio...

Abstract

This invention discloses a method and a system that PPP link transmits DHCP messages and gets collocation information, in which, the terminal of the PPP link transmits DHCP broadcast messages via PPP link directly to replace necessary hardware address in the DHCP message with flags identifying the devices using the PPP link only so the PPP link can support DHCP, amd the flags can be ID of devices or link numbers.

Description

technical field [0001] The invention relates to the communication field, in particular to the communication technology based on the point-to-point protocol. Background technique [0002] 3G is the abbreviation of 3rd Generation in English, referring to the third generation of mobile communication technology. Compared with the first-generation analog mobile communication technology and the second-generation Global System for mobile Communication (GSM for short), Code Division Multiple Access (CDMA for short) and other digital mobile communication technologies, Generally speaking, 3G refers to a new generation of mobile communication system that combines wireless communication with multimedia communication such as the Internet. It can handle various media forms such as images, music, and video streams, and provide various information services including web browsing, teleconferencing, and e-commerce. [0003] In a 3G system, the network side includes a base station controller...
