Problems solved by technology

[0006]Aiming at the current method of realizing mutual migration between PC and SPC, from the perspective of the management plane, the call processing process is not considered, and the problem of re-allocation of resources is not involved. The invention aims to provide a management plane implementation method for permanent connection and soft permanent connection migration to solve the above problems

Embodiment 1

[0045] image 3 It is a flowchart of a method for realizing the management plane of PC to SPC migration according to Embodiment 1 of the present invention, such as image 3 As shown, the implementation method of the management plane of PC to SPC migration includes the following steps:

[0046] Step S302, the EMS judges whether there is already a call that the SPC will migrate to according to the PC service that needs to be migrated, and determines to execute the corresponding call processing (call process) according to the judgment result; wherein, the call processing specifically includes: call establishment processing, call modification deal with;

[0047] Wherein, in the case that the judgment result is negative, a call establishment process needs to be performed, that is, the EMS initiates a call establishment process (refer to Table 3) to the control plane of the source end node (i.e., ASON); at this time, the above step S202 Call processing is call establishment proce...

Embodiment 2

[0062] Figure 4 It is a flow chart of a management plane implementation method for SPC to PC migration according to Embodiment 2 of the present invention, as Figure 4 As shown, the implementation method of the management plane of SPC to PC migration includes the following steps:

[0063] Step S402, the EMS judges according to the migrated SPC service whether the SPC to be migrated corresponds to all connections of the call, and determines the call processing to be executed according to the judgment result; wherein, the call process specifically includes: call deletion processing, call modification processing;

[0064] In the case that the judgment result is negative, the call processing is call modification processing. In this way, the EMS deletes the selected (that is, the SPC to be migrated) from the call in the process of executing the call processing according to the existing call selected by the user. That is to say, when the call does not need to be deleted (the call ...

Abstract

The invention discloses a method for realizing a management plane of permanent connection and soft permanent connection transplantation, which is applied to an automatic interactive optical network. The method comprises the following steps: a network element management system executes call processing correlative to the transplantation operation of permanent connection and soft permanent connection; the network element management system issues a transplantation request to a control plane, and information used for indicating the call processing is carried in the transplantation request; and the network element management system receives a transplantation result from the control plane, redistributes resources according to the transplantation operation under a condition that the transplantation result is successful, and reports the information of the call processing and a result of resource redistribution to a network management system. The invention combines the process of the mutual transplantation of PC and SPC and the processes of the resource repartition and the call processing on the management plane together and comprises the processes of call establishment, call modification and call deletion, thereby the invention better conforms to the essence of ASON defined by ITU-T in the aspects of the principle and the concept.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a management plane implementation method for PC (Permanent Connection, permanent connection) and SPC (Soft Permanent Connection, soft permanent connection) migration. Background technique [0002] ASON (Automatic Switched Optical Network) is a new generation of optical transmission formulated and standardized by ITU-T (ITU Telecommunication Standardization Sector) and automatically completes the switching function by introducing the control plane. ASON includes transmission plane, control plane and management plane, and supports PC, SPC and SC (Switched Connection, switched connection) three connection modes, among which, the permanent connection PC is completely established by the management plane through assignment , both the soft permanent connection SPC and the switched connection SC are completed by the control plane to complete the connection establishment process. [00...
