Problems solved by technology

Although this approach can avoid the overhead and delay caused by the SS sending bandwidth application requests, the base station needs to periodically specify the size of the burst information unit in the MAP message
When there are a large number of VoIP users under a base station, the overhead of MAP messages occupies a large amount of bandwidth resources, affecting spectrum efficiency and sector capacity

Embodiment Construction

[0016] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] figure 1 It is a flow chart of the real-time service bandwidth resource allocation method according to the present invention. Such as figure 1 As shown, the method includes the following steps: Step S102, the base station reserves resource blocks for real-time services and periodically notifies the user stations of the information of the reserved resource blocks by broadcasting, and the user stations store the information of the reserved resource blocks. Step S104, when the user station initiates a real-time service request, the base station allocates resources in the reserved resource block for the real-time service according to the usage of the reserved resource block and notifies the user station of the resource allocation information. In step S106, the user station stores resource allocation information and uses the a...

Abstract

The invention provides a real-time service bandwidth resource allocation method, which comprises the following steps: step S102, reserving a resource block for a real-time service by a base station, periodically notifying the information of reserving the resource block in the broadcast manner to a user station to reserve, and storing the information of the resource block by the user station; step S104, allocating the resources in the reserved resource block for the real-time service by the base station according to the use condition of the reserved resource block under the condition that the user station initiates a real-time service request, and notifying the user station of the resource allocation information; and step S106, storing the resource allocation information by the user station, and executing the real-time service by using the allocated resources according to the resource allocation information. The method can reduce the cost for the real-time service bandwidth allocation based on OFDMA, and further improve the sector capacity of the system.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a real-time service bandwidth resource allocation method. Background technique [0002] Next-generation mobile communication systems such as mobile WiMAX are mainly based on the OFDMA (Orthogonal Frequency Division Multiple Access) multiple access method. Under a given system bandwidth, from the perspective of the frequency domain, different users occupy a certain The number of orthogonal subcarrier resources is used to achieve the purpose of multiple access. [0003] In the mobile WiMAX (Worldwide Interoperability for Microwave Access) system based on the IEEE802.16e standard, for the real-time VoIP (Voice over IP Service) service, the scheduling service mode of UGS (Unsolicited Grant Service) is adopted. In UGS scheduling service, BS (base station) periodically grants burst information elements (Data Grant Burst IEs) to SS (subscriber station). Although this approach can a...
