Embodiment 1

[0029] figure 1 The implementation process of the method for call access control provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0030] In step S101, an access request is received.

[0031] In this embodiment, the access request includes, but is not limited to, a call type request and a switch type request. The call type request corresponds to two service types of voice and interactive data, and the switch type request corresponds to two service types of voice and interactive data. When the HAPS system receives an access request, according to the access request, according to the service type and call type corresponding to the access request, calculate the current average uplink quality, and judge whether it is greater than the access request corresponding to the access request Threshold, so as to control new users or interrupt switching users, so as to limit the number of users and ensure the call quality of users.

Embodiment 2

[0055] Figure 4 A specific structural block diagram of the apparatus for call access control provided by Embodiment 2 of the present invention is shown. For convenience of description, only parts related to the embodiment of the present invention are shown. In this embodiment, the device for call access control includes: an access threshold setting unit 41, a request receiving unit 42, a first link quality acquisition unit 43, a second link quality acquisition unit 44, and an access judgment unit 45 , the second link quality acquisition unit 44 includes: a weighting factor setting module, a third link quality acquisition module and a second link quality acquisition module.

[0056] Wherein, the access threshold setting unit 41 is configured to set the priority level of the service corresponding to the access request, and set the access threshold corresponding to the call types of different services.

[0057] a request receiving unit 42, configured to receive an access reques...

Abstract

The invention belongs to the technical field of communication and provides a method and device for call admission control and a high altitude platform communication system. The method for call admission control comprises the following steps that an admission request is received; according to a service type and a call type which correspond to the admission request, a wireless link model is determined, and the quality of a first uplink is obtained; according to the quality of the first unlink and the quality of a fourth uplink, the quality of a second uplink is obtained; whether the quality of the second uplink reaches the admission threshold corresponding to the admission request is judged, if yes, response to the admission request is conducted, and admission is accepted, and if not, the admission request is rejected. According to the method and device for call admission control and the high altitude platform communication system, the problem of control over multiple services of the high altitude platform communication system in the swinging state is solved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and device for call access control and a high-altitude platform communication system. Background technique [0002] High altitude platform communication (HighAltitudePlatformStations, HAPS) is a new means of mobile communication. The HAPS communication network refers to a network composed of a high-altitude platform (High Altitude Platform, HAP) that resides in the space for 5-10 years at a height of about 20-100Km in the near-earth space. In the space range, a stable communication platform is used as a microwave relay station, a communication system composed of ground control equipment, entrance equipment, and various wireless users. The high-altitude platform can be integrated with the satellite ground network, or can be independently networked with the ground. The communication platform Synchronized with the rotation of the earth, it can stay in the...
