Problems solved by technology

Therefore, if the existing FDD system supports VOIP services and reduces the control channel overhead solution directly to the TDD system is not suitable
Moreover, in view of the characteristics of the TDD system and the requirements of the VOIP service, the relevant technologies adopted in the existing TDD system are not conducive to supporting the VOIP service
For TDD systems, there is currently no effective solution to support VOIP services and reduce control channel overhead

Embodiment 2

[0151] Method embodiment two: a solution for effectively reducing control channel overhead by adopting a semi-static resource scheduling method for scheduling in the downlink direction. The implementation process of this embodiment includes the following steps:

[0152] Step 301. In the link establishment phase, the network configures the maximum amount of physical resources occupied by the traffic channel and the control signaling resources carried by the control channel for the VOIP UE. The downlink TBS used to transmit downlink VOIP data blocks on the traffic channel and the physical resources corresponding to the downlink TBS can be preset through the protocol fixed setting method and the high-layer signaling setting method. In addition, the timing relationship between the traffic channel and the control channel can be preset in a protocol fixed setting mode and a high-layer signaling setting mode.

[0153] Step 302, the base station periodically detects the size of the d...

Abstract

The invention discloses a semi-static resource scheduling method, which comprises the following steps: largest physical resource magnitude that is occupied by business channels, transmission block size (TBS) and physical resources that are corresponding to the TBS are configured; when the TBS is chosen according to network telephone (VOIP) data block size that is loaded by the present business channel, the physical resource magnitude that is occupied by the present business channel is computed according to the TBS and the physical resources corresponding to the TBS; balance of the physical resource that is occupied by the present business channel is obtained according to the largest physical resource magnitude and the occupied physical resource magnitude, and the physical resource balance is determined as adjusting information and encapsulated in a control signaling which is sent to network equipments and used for scheduling. The invention further discloses a semi-static resource scheduling system, a retransmission-optional scheduling method and a retransmission-optional scheduling system that are based on semi-static scheduling. The methods and the systems of the invention can realize VOIP business support and effectively reduce the cost of control channels at the same time.

Description

technical field [0001] The present invention relates to scheduling technology, in particular to a semi-static resource scheduling method and system supporting VOIP services, and a retransmission selection scheduling method and system based on the semi-static scheduling technology. Background technique [0002] The 3rd Generation Partnership Project (3GPP), as the organization that formulates 3G technical specifications, introduced high-speed downlink packet access (HSDPA) technology and high-speed uplink packet access (HSUPA) technology in R5 and R6 respectively, and the two are collectively referred to as high-speed Packet Access (HSPA) technology. In addition, the IP transmission mechanism is introduced into the network architecture of R5. With the development of technologies such as IP Multimedia Subsystem (IMS, IP Multimedia Subsystem), it has gradually become a trend to provide voice services through IP networks. support. [0003] In the following, the characteristic...
