Problems solved by technology

[0005] First of all, E1 interruption directly leads to the interruption of call services, which brings serious losses and negative impacts to users and operators;
[0006] Secondly, when diverting or maintaining existing equipment transmission, engineering personnel often put such construction in the evening when there is less traffic, which brings great inconvenience to the construction of engineering personnel and increases maintenance costs

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as figure 2 , 3 , 4, the present invention sets more than one E1 link between the devices connected through E1, which is a necessary condition for implementing the present invention. figure 2 The middle thick line indicates that there is traffic occupying the time slot, and the thin line indicates idle E1; image 3 The middle dotted thick line part E1 is interrupted; Figure 4 Traffic indicating an outage is transferred to the thin solid line. In order to ensure that the traffic between connected devices occupies the least E1 circuit, when the service processing module allocates traffic time slots on the E1 circuit, it will give priority to allocating the traffic to the E1 circuit that is not full. The communication system of the present invention has the ability to monitor E1 failures and monitor each E1 link in real time. Such as image ...

Abstract

This invention discloses a traffic protection method based on E1 circuit, which designs multiple E1 links between the devices butt jointed by E1 including: 1, when a testing an abnormal E1 circuit, the system informs the service process module, 2, which searches for time slot cluster occupied by traffic on the abnormal E1 circuit and finds if there are normal idle E1 circuit and finds if there are normal idle E1 circuits between the butt-jointed devices, if not, it finishes the steps, if so, it enters into step 3, 3, the service process module transfers the abnormal traffic on E1 circuit to normal idle E1 circuit and informs the butt-joint device to finish the re-connection and also finishes re-connection itself.

Description

technical field [0001] The present invention relates to a traffic protection method based on an E1 circuit in a communication system, in particular to a PHS (Personal Handphone System, personal hand-held phone system), GSM (Global System for Mobilecommunication, Global System for Mobile Communication), fixed-line, narrowband A traffic protection method based on an E1 circuit in systems such as CDMA (Code Division Multiple Access, Code Division Multiple Access). Background technique [0002] In PHS, GSM, fixed-line, and narrowband CDMA in the communication field, E1 (European Telecom No. 1 standard) is used for transmission, and each call service is completed on a 64Kbps time slot of E1. Regarding E1, it is clearly stipulated in the 703rd document of the International Telecommunication Union Committee (ITUG.703) that an E1 is a 2.048M link, encoded with PCM (Pulse Code Modulation, pulse code modulation); the frame length of E1 is 256 bits , divided into 32 time slots, one ti...
