Problems solved by technology

But so far, in the field of digital trunking, there is no public literature for the busy notification service
However, the differences in the network environment, business and user characteristics in the field of digital trunking have resulted in the solution of busy call prompts in other communication systems not being applicable to the professional field of digital trunking

no. 1 example

[0049] In this embodiment, a user in the digital trunking system has activated the busy notification service, and when the user is in a certain trunking service, a user initiates a single call to him, such as image 3 shown, including the following steps:

[0050] Step 301, a cluster user initiates a single call to another cluster user, and sends a cluster call establishment request to the PDS;

[0051] Step 302, the PDS decodes the call setup request from the trunking terminal, and judges whether the format of the request message is legal, and if so, sends a call authentication request to the PHR, otherwise directly rejects the call setup request;

[0052] The call attribute identifier is carried in the call authentication request sent by the PDS.

[0053] Step 303, after the PHR receives the call authentication request, it queries the cluster user database, first authenticates whether the calling party is legal, determines whether the calling party is a legal user, whether ...

no. 2 example

[0061] In this embodiment, one or some users in the digital trunking system have opened the busy notification service. Figure 4 shown, including the following steps:

[0062] Step 401, a user in the group initiates a group call and sends a call setup request to the PDS;

[0063] Step 402, the PDS decodes the call establishment request from the trunking terminal, and judges whether the format of the request message is legal, and if so, sends a call authentication request to the PHR, carrying the call attribute identifier, otherwise directly rejects the call establishment request;

[0064] Step 403: After receiving the call authentication request, the PHR queries the cluster user database, first authenticates the calling party, and then authenticates the called party, that is, other group members. If the authentication is passed, determine if there are members in the group It is the active user of the busy prompt service, and if so, an authentication response message is return...

no. 3 example

[0074] In this embodiment, when a certain user in the digital trunking system has activated the busy notification service, and the user is in a non-trunking service (such as ordinary voice call, data service, etc.), another user initiates a notification service to the user. single call, such as Figure 5 shown, including the following steps:

[0075] Step 501, the called terminal is in a high-priority non-trunk service. For the case where the original call has the same priority as the new call, the called terminal is still considered to be in the "high-priority" service;

[0076] Step 502 is the same as step 301-step 303 in the first embodiment, and will not be repeated here;

[0077] Step 503, after the PDS receives the authentication response message, it judges that the called terminal is in a non-cluster call, and sends a call connection request of the called terminal to the base station subsystem (BSS);

[0078] Step 504, the BSS judges that the called terminal is in a n...

Abstract

A method for realizing a busy notification service in a digital trunking communication system, which is applied to a digital trunking system based on CDMA2000 technology, comprising the following steps: (a) a trunking user initiates a trunking call, and after the authentication of the scheduling home register passes, if any If the caller is a busy prompt service activation user, then the authentication response message carries the called busy prompt service opening sign and the priority information of this call; (b) after the dispatching server receives the authentication response message, If it is determined that the called terminal is in a busy state, the priority of the new call is not higher than its current service, and the called party has opened a busy notification service, then send a busy notification message to the called terminal; c) After receiving the busy prompt message, the called terminal displays it to the user. The method of the invention can provide calling information to the called in time without affecting the calling service that the called is participating in, and the user can choose whether to open the function of prompting when the busy is active.

Description

technical field [0001] The invention relates to the field of digital trunking communication, in particular to a method for realizing busy prompting of trunking users in a digital trunking communication system. Background technique [0002] The trunking communication system is an advanced mobile dispatching system, which represents the development direction of a dedicated mobile communication network, one of the communication systems. The trunking communication system has the function of sharing available channels for all users of the system and automatically selecting channels. It is a multi-purpose and high-efficiency wireless dispatching communication system for sharing resources, sharing costs, and sharing channel equipment and services. [0003] For the basic network architecture of the digital trunking communication system, see figure 1 As shown, it includes cluster terminal 1, base station subsystem 2 and cluster scheduling subsystem 3, wherein: [0004] cluster term...
