Abstract

The invention discloses a method which belongs to the network communication technical field and connects with a remote maintenance communication system in a semi-fixed way through E1. The method is realized though that a route is connected, set and maintained through E1 in a semi-fixed way and every switching device distributes a device address. The invention mainly solves the difficulties of the route decision of maintenance station messages and the message transmission relaying on a center switch. Therefore, a plurality of remote communication devices can be ensured to be maintained in local.

Description

A kind of method by the E1 semi-fixing continuing remote maintenance of communication system

Technical field

The invention belongs to network communications technology field, particularly a kind of method in the dispatching communication command system by the E1 semi-fixing continuing remote maintenance of communication system.

Background technology

In the dispatching communication command system, especially in a bigger dispatching communication network, a plurality of switching equipment are arranged usually, the user wishes usually to these equipment centralized maintenance, and not wishing increases new network again, utilizes prior network device to carry out centralized maintenance.At present, the connection major part of switching equipment is all used E1, builds semi-fixing continuing by a certain fixedly time slot of E1 and can carry out remote maintenance.But, adopt this mode to carry out remote maintenance now and generally just be applied to simple network configuration, as shown in Figure 1, on a tandem switch, directly connect several switches.As shown in Figure 2, two tandem exchanges are arranged, like this, the message that is issued to switch from maintenance console need select correct route just can send on the switch, the message that same switch sends to maintenance console also need be selected correct route, will tell simultaneously which switching equipment is maintenance console message come from, particularly on tandem switch 4, the routing decision and the forwards of maintenance console message have certain difficulty.

Summary of the invention

The purpose of this invention is to provide a kind of method by the E1 semi-fixing continuing remote maintenance of communication system,

As follows for realizing the technical scheme that purpose of the present invention adopts, comprising:

To switching equipment distribute one fixing and also in network unique device address (more than or equal to 1);

2. distribute one to receive the route that parent office is safeguarded for each switching equipment;

3. the route of safeguarding from maintain message to junior office that transmit is set, promptly which E1 transmits maintain message by to junior office;

At maintenance console in the message that switching equipment sends, message header will comprise the device address of switching equipment.When switching equipment was received the message of maintenance console transmission, at first whether the judgment device address was local address like this, if, then handle this message, otherwise search maintaining routing list, judge which E1 to transmit this message by;

At switching equipment in the message that maintenance console reports, fill in equipment sources address and destination address, source address is the local device address, destination address adds 0; In network, any one switching equipment receives that destination address is after 0 the message, all transmits to parent office or maintenance console.

The invention has the beneficial effects as follows to be mainly the difficulty that solves routing decision and forwards in the background technology, thereby guarantee to safeguard long-range a plurality of communication equipments in this locality.

Description of drawings

Fig. 1 is a simple dispatching communication network;

Fig. 2 is the dispatching communication network of a complexity;

Fig. 3 is issued to the flow chart of remote switch equipment for maintain message in the execution mode;

Fig. 4 feeds back to the flow chart of local maintenance platform for acknowledge message in the execution mode.

Embodiment

For the present invention there being further understanding, consult communication system shown in Figure 2 below, be issued to the flow chart of remote switch equipment in conjunction with maintain message shown in Figure 3, the present invention will be described in detail by the local maintenance platform remote switch equipment (switch 6) to be carried out example that data are provided with, and concrete steps are:

S301, tandem switch 1 receive the maintain message that maintenance console issues;

The destination device address of S302, parsing maintain message, the discovering device address is a switch 6;

S303, the route of safeguarding of searching switch 6 need to transmit this message to tandem switch 4;

After S304, tandem switch 4 receive this message, resolve this maintain message equally, search the route of safeguarding of switch 6, transmit this message to switch 6;

S305, switch 6 receive this message, and the destination device address of resolving maintain message is the address of oneself, and local switching equipment is carried out the data setting.

Acknowledge message feeds back to the flow chart of local maintenance platform as shown in Figure 4.The process of acknowledge message feedback is:

S401, switch 6 send acknowledge message to tandem switch 4, and source address is that switch 6 is established each address in the acknowledge message, and destination address adds 0;

S402, tandem switch 4 receive the confirmation message, resolve the destination device address of maintain message, find that the destination device address is 0, transmit this message to parent office (tandem switch 1);

After S403, tandem switch 1 receive message, resolve equally and find that the destination device address is 0, send this message to maintenance console;

After S404, maintenance console are received acknowledge message, resolve message,, finish to the data setting of reported by maintenance personnel switch 6 because source address is the device address of switch 6 in the message; Finish to safeguard.

Claims

1. the method by the E1 semi-fixing continuing remote maintenance of communication system is characterized in that, this method by the E1 semi-fixing continuing, be provided with and safeguard route and for realizing each switching equipment address of allocating a device;

The described route of safeguarding comprises route that receives the parent office maintenance and route from maintain message to junior office that transmit;

Described device address is the address of maintenance console to switching equipment transmission message, reaches the foundation that switching equipment is handled or transmitted this transmission message;

Distribute one to receive route and route from maintain message to junior office that transmit that parent office is safeguarded for each switching equipment;

Route from maintain message to junior office that transmit is set;

When described switching equipment was received the message of maintenance console transmission, at first whether the judgment device address was local address, if, then handle this message, otherwise search maintaining routing list, judge which E1 to transmit this message by;

Described maintenance console will comprise the device address of switching equipment in the message header in the message that switching equipment sends;

Described switching equipment is in the message of handling or transmit the maintenance console transmission or in the message that maintenance console reports, fill in equipment sources address and destination address, when described destination address is 0, any one receives that destination address is the switching equipment of 0 message, all transmits to parent office or maintenance console.

2. method according to claim 1 is characterized in that, described device address be one fixing and also in network unique address, its scope is more than or equal to 1.
