Problems solved by technology

[0027] Therefore, according to the current plan, as long as the status of each user in the group changes, the POC server will immediately notify each member of the group. At this time, the NOTIFY message will increase geometrically, and the load on the network and each POC terminal will greatly increase.

Embodiment Construction

[0065] The core of the present invention is to propose a scheme to reduce the frequency of NOTIFY transmissions for the very high frequency of NOTIFY transmissions, because the connection status of each group member in the packet domain cannot be all in an active state, and some POCs are called The terminal is set to manual answering and requires user confirmation, so the time for each called member to respond to the POC server is different, but the response time span of each member is not very large. Therefore, the present invention can add a notification timer to each group session in the POC server, and the duration of the timer can be modified. The POC server starts the notification timer when it initiates an invitation to each called party. When the notification timer expires, the POC server detects the status of each member of the group and uniformly notifies each group member. Immediately notify when the last called member to enter the session changes status to Connecte...

Abstract

The invention relates to a method for informing the member condition of POC server group, and relative device. Wherein, it is characterized in that: based on high NOTIFY sending frequency, it provides a method to reduce said frequency; and adds one inform timer for each group conversation in the POC server, while the time length of said timer can be modified. The invention comprises: POC server starts the inform timer when sends requests to each called user; when the inform timer is over time, POC server detects the member condition of group to inform all members; therefore, the invention can reduce the working load of network and POC terminal.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for notifying the status of members of a POC service group. Background technique [0002] The concept of POC (PTT over Cellular, push-to-talk based on cellular system) service comes from walkie-talkies. In the group, only the members who have the right to speak (Floor) can speak, and other members answer. By pre-setting the call group, the user does not need to dial a number during the call, and the voice can be transmitted to all other members in the group at the same time by pressing and holding a specific button. The call and the call connection process are completed in an instant. The receiving party can answer the call without any response. The half-duplex method is used in the call process. When one party is speaking, the other members can only answer and cannot speak. [0003] When a POC terminal user initiates a predefined group call, th...
