Embodiment Construction

[0017] The specific scheme adopted by the present invention to solve the technical problem is: after the VoIP service reaches the MAC layer, the VoIP admission control function starts to start. First, the arrival of a new VoIP connection (1) or the arrival of a VoIP switching connection (2) detects whether there is a VoIP that needs to be accessed, and if so, extracts the QoS parameters required to access the VoIP. Before accepting the judgment, the number of accepted UGS connections N is obtained according to the updated number of VoIP accepted and the quality of service (5) k UGS , rtPS connection number N k rtPS .

[0018] It should be noted that for IEEE 802.16e, N in all descriptions k rtPS should be replaced by N k e-rtPS , because there is no e-rtPS service type in IEEE 802.16-2004, VoIP with silent compression is transmitted through rtPS, while in IEEE 802.16e, VoIP with silent compression is transmitted through e-rtPS service type.

[0019] Second, according t...

Abstract

The method comprises: VoIP net connection arrival; VOIP switch connection arrival; calculating the bandwidth required by connection; acceptance controlling decision; updating the accepted VoIP amount and its QoS; triggering the allocation of bandwidth and the relevant message management. Its working steps comprise: a) detecting the connection arriving request; calculating the bandwidth required by the connection; c) acceptance controlling decision; d) updating the accepted VoIP amount and its QoS; e) triggering the allocation of bandwidth and the management of relevant messages.

Description

technical field [0001] The invention relates to a VoIP admission control method in a communication network. Background technique [0002] With the rapid development and integration of wireless communication and the Internet and the growing demand of users for multimedia services, how to meet more user access on the basis of ensuring QoS has become one of the difficulties in wireless resource management. Since the announcement of IEEE 802.16-2004 and IEEE802.16e standards, the future access network will change from wired to wireless, and the switching technology of wireless networks has also begun to change from circuit switching to packet switching. The VoIP service's requirement for service quality is no longer a fixed value, but can be adjusted within a certain range, resulting in a certain degree of flexibility for the VoIP service's requirement for network resources, which can be adjusted within a certain range according to the load status of the network Its network res...
