Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0038] The shortwave wireless coordination method provided in this embodiment includes the following steps:

[0039] Step S11, update the user contact list information.

[0040] In order to achieve multi-hop relaying and forwarding of datagrams between on-site users belonging to the same subnet, it is necessary to provide a mechanism to maintain the user contact list information of on-site users, so that the accuracy and real-time performance of the user contact list in...

Abstract

The invention is suitable for the technical field of shortwave wireless communication and provides a shortwave wireless cooperation method. User contact list information is stored in on-site users in a subnet; user validity judgment is carried out in a link establishment process; when a link cannot be established, a source user initiatively searches a relay user and a timer is arranged; no matter what relay result can be sent to the source user within the time limit of the timer; through searching the relay user, the success rate of link establishment of the source user and a target user is guaranteed, and the method appears to be particularly important in emergency circumstances, such as emergency relief.

Description

technical field [0001] The invention belongs to the technical field of short-wave wireless communication, and in particular relates to a short-wave wireless coordination method. Background technique [0002] Short-wave wireless communication enables fast and convenient information exchange between on-site users belonging to the same emergency response department in emergencies such as emergency relief and disaster relief. These users are included in a wireless communication subnet, and the contact address and frequency set are uniformly assigned. Rely on the private network frequency selection fast link technology to provide users with data and voice services. [0003] On-site users can send short messages, e-mails, code commands and other information through the private network collaborative data service process after completing the rapid frequency selection and link building, and can also perform digital voice communication at a rate of 600bps through the private network c...
