Embodiment 1

[0042] This embodiment introduces a method for establishing a mutual aid communication channel between a home network and a neighboring home network in G.hn. image 3 is a schematic diagram of a mutual assistance communication channel establishment process according to an embodiment of the present invention, such as image 3 As shown, the process includes the following steps (step S302-step S324):

[0043] Step S302, source device A in home network A exchanges ND_reserve.req / ND_reserve.cnf messages with G.hn domain master A, domain master A reserves bandwidth between source device A and intermediate device A, and at the same time provides Bandwidth is reserved between device A and intermediate device B.

[0044] Step S304, the source device A sends ND_channel.req to the intermediate device A, requesting the intermediate device A to establish a mutual aid communication channel with the intermediate device B in the neighboring home network B.

[0045] In step S306, the interme...

Embodiment 2

[0056] Embodiment 2 (OTDR reporting)

[0057] This embodiment introduces the process of establishing a mutual aid communication channel between the source device A and the uplink device B in the OTDR reporting mode. Figure 4 It is a schematic structural diagram of an external OYDR device at the ONU of the passive optical network according to an embodiment of the present invention, such as Figure 4 As shown, when a fault such as a break occurs in the branch optical fiber A, the OTDR device at the ONU A place locates the location of the optical fiber fault, and the ONU A initiates the establishment of a mutual aid channel as the source device A, and the home gateway acts as the G.hn domain master A. The method in Example 1 establishes a mutual aid communication channel between the source device A and the uplink device B (ONU B), and ONU A reports the OTDR detection result to the OLT through the uplink device B (ONU B), which carries the relevant information of the ONU informa...

Embodiment 3

[0058] Embodiment 3 (Dying Gasp report)

[0059] This embodiment introduces the process of establishing a mutual aid communication channel between the source device A and the uplink device B in the Dying Gasp reporting mode. When ONU A is powered off, inform the home gateway (G.hn domain master A) of the power outage information, and the home gateway acts as source device A and G.hn domain master A at the same time, requesting to establish mutual assistance with ONUB (uplink device B) communication channel, and report the Dying Gasp of ONU A to the OLT, which carries the relevant information of the ONU.

[0060] When ONU A is powered off, it can also broadcast the Dying Gasp message in the home network, G.hn domain master A will try to establish contact with the uplink device B (ONU B) of the neighbor network, and pass the Dying Gasp of the ONU through the neighbor network The uplink device sends it to the OLT, which can carry the relevant information of the ONU, which is use...

Abstract

A method and apparatus for establishing a channel are disclosed. The method includes: a home network transmitting a channel establishment request to a neighbor home network; and after receiving a confirmation response from the neighbor home network, the home network establishing a mutual-aid communication channel with the neighbor home network. The apparatus includes a channel request module and a channel establishment module.

Description

technical field [0001] The present invention relates to the communication field, in particular to a channel establishment method and device. Background technique [0002] In the broadband optical access technology, the passive optical network is composed of an optical line terminal (Optical Line Terminal, OLT for short), an optical splitter, and an Optical Network Unit (ONU for short). figure 1 It is a schematic diagram of the composition structure of the passive optical network according to the related technology, such as figure 1 As shown, in the passive optical network, the OLT is connected to the optical splitter through the main optical fiber, and the optical splitter is connected to each ONU through the branch optical fiber. Due to aging or external force, the optical fiber may be broken, which further leads to the failure of normal communication between the OLT and the ONU. [0003] In order to repair the breakpoint of the fiber, it is necessary to locate the breakp...
