Embodiment Construction

[0024] In this embodiment, a downlink VoIP service scheduling method is provided.

[0025] Preferably, the downlink VoIP service scheduling method according to this embodiment can be executed with the flow shown in FIG. 3 .

[0026] As shown in Figure 3, the downlink VoIP service scheduling method according to the present embodiment includes: step S302, the wireless communication system pre-allocates a wireless resource set (Resource Set) and an MCS set for the first transmission and first retransmission of the downlink VoIP service packet; S304, the base station selects from the pre-allocated radio resource set and MCS set, and sends or retransmits the VoIP packet for the first time through the selected radio resource and MCS; and step S306, the terminal sends Collectively receives VoIP packets that are sent for the first time or resent for the first time.

[0027] Wherein, when the base station needs to perform the first transmission or the first retransmission of the VoIP ...

Abstract

The utility model discloses a dispatching method for the descending VoIP business, comprising a step S302, a step S304 and a step S306; wherein the step S302 is that the wireless communication system transmits and retransmits firstly the pre-assigned wireless resources integration and MCS integration to the descending VoIP business grouping; the step S304 is that the base station makes option from the pre-assigned wireless resources integration and MCS integration and makes the first transmission or retransmission to the VoIP grouping through the selected wireless resources and MCS; the step S306 is that the terminal receives the first transmitted or retransmitted VoIP grouping according to the pre-assigned wireless resources integration and the MCS integration. The utility model has advantages of reducing fully the dispatching expenses and obtaining more dispatching flexibility and self-adaptive capacity.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a downlink voice over IP (VoIP) service scheduling method. Background technique [0002] Figure 1 shows the general structure of a wireless communication system. As shown in Figure 1, a wireless communication system is mainly composed of a terminal, a base station, and a core network. Base stations can have logical or physical connections as needed, and a network composed of base stations is called a radio access network (RAN), which is responsible for access layer affairs, for example, management of radio resources; uplink and downlink radio resources according to The base station is responsible for scheduling in the way of sharing the channel. The base stations are all connected to the core network, and each base station can be connected to one or more core network nodes (CN). The core network is responsible for non-access layer affairs, such as billing and loc...
