Embodiment Construction

[0053] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0054] see figure 1 , a method for selecting a communication path provided by an embodiment of the present invention, the method is applicable to a 4over6mesh network, and the method includes:

[0055] 101. Maintain configuration information of at least one channel state information reference signal CSI-RS in an idle state.

[0056] Wherein, one CSI-RS is used to correspond to one transmission point, and all transmission points maintained by the terminal can be used as a CoMP set. The CoMP set may be a CoMP cooperating set (CoMP cooperating set), a CoMP measurement set (CoMP measurement set) or a resource management set (resource management set, RM set). The CoMP cooperating set is a collection of transmission points that directly or indirectly participate in transmitting data for a terminal on a time-frequ...

Abstract

The invention discloses a communication path selection method and device. The method comprises the following steps: maintaining configuration information of at least one channel state information reference signal CSI-RS in an idle state; when a source end router detects that the communication between the source end router and a host end router fails, selecting an optimal routing path from the source end router to the host end router from a backbone network; and determining an optimal routing path as a communication path between the source end router and the host end router, and sending CSI-RSinformation corresponding to the configuration information of the at least one CSI-RS to a serving base station when the idle state is recovered to a connected state. Thus, in the 4over6 mesh network,when a certain communication on the IPv6 backbone network fails, the optimal routing path from the source end router to the host end router is selected from the backbone network, and the selected optimal routing path is used as the communication path between the source end router and the host end router, so that the purpose that the IPv4 networks based on the communication can still communicate with each other can be achieved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a communication path selection method and device. Background technique [0002] Design of mesh architecture (4over6 mesh network for short) network interconnection mechanism based on Internet Protocol Version 6 (IPv6) and Internet Protocol Version 4 (IPv4) A 4over6 system based on dynamic non-explicit communication is realized. The system adopts a large-scale distributed design, which provides an important solution for the construction of a pure IPv6 backbone network and accelerates the transition to IPv6, and can solve the problem of interconnection of IPv4 networks through a pure IPv6 backbone network. The protocol extension (Multi-Protocol extension to BGP, MP-BGP) protocol realizes the propagation of IPv4 customer network routing information among border routers of IPv6 backbone network. [0003] Generally speaking, the 4over6 mechanism includes the control...
