Abstract

The invention discloses an analog and digital DMR compatible intercom small cluster construction method, and the construction method thereof comprises the following steps: A. the addressing allocationdefinitions of various IDs of the system networking include: (1), DMR ID addressing; (2), composition of the system networking IDs; and (3), combination definition of system extension SYS ID and DMRID and terminal ID address and group selective call ID address allocation. By specially designing the coding of the device ID, the invention adopts the arrangement combination of the system, base station, channels, number and priority, reasonably arranges the common information of the intercom, combines the traditional analog intercom system and the new digital intercom system through reasonable system planning under a reasonable ID programming mode to form a small cluster, and makes the intercom users in these channels be interconnected. Not only old equipment is used, but also new digital intercom may be introduced more reasonably, so that users and suppliers can all smoothly adapt to the upgrade of the intercom technology.

Description

Technical field [0001] The invention relates to the field of communication technology, in particular to a method for constructing a small intercom cluster compatible with analog and digital DMR. Background technique [0002] At present, there are a large number of analog intercom systems, but the current analog systems only have voice, not digitization, especially there is no ID data of the intercom call and no identification of the initiator and target of the talk, which leads to the management of the intercom. The joint use of channels is very inconvenient. [0003] The DMR protocol is a new type of digital mobile radio communication technical specification proposed by the European Telecommunications Standards Institute (ETSI) in 2004. It is a new standard in the field of professional mobile radio (PMR). Compared with other professional wireless communication products, The DMR protocol mainly has the following advantages: ① Higher spectrum utilization: Spectrum is a strategic re...
