Problems solved by technology

Since the above-mentioned traditional packet scheduling does not consider the impact of packet delay, it cannot reduce the delay of non-real-time connections. Therefore, a packet scheduling strategy for these delay-sensitive business characteristics is needed to effectively improve service quality.

Embodiment Construction

[0032] In this specification, a wireless communication system or a mobile communication system refers to a network system in which at least one of the two ends of the exchange information can be in a mobile state. Examples include but are not limited to cellular mobile systems, paging systems, and satellite communication systems. , Cordless telephone system, mobile trunking communication system, etc.

[0033] In the following description, packet scheduling refers to allocating available air interface resources among users of non-real-time services, such as allocating transmission channels for each user's packet data, monitoring packet data distribution and network load. It is worth noting that the channels mentioned here include various channels, such as public channels, dedicated channels and shared channels.

[0034] In the following description, the scheduling priority of a packet data indicates the degree to which the packet data is prioritized in a packet scheduling proce...

Abstract

The disclosed scheduling method for grouping business comprises: an input unit for business type and overtime, an order unit with a first unit to group and order data into multiple data sequence and a second unit to obtain the data PRI as overtime, and an allocation unit to allocate interface resource. This invention is convenient and simple.

Description

technical field [0001] The invention relates to wireless resource management technology in a wireless communication system, in particular to a method and device for scheduling packet services in a wireless communication system. Background technique [0002] Traditional packet scheduling algorithms are generally divided into three categories: fair throughput scheduling, fair time scheduling and C / I (carrier-to-interference ratio) scheduling. Fair throughput scheduling does not consider the location of users, and provides the same rate for all users, that is, users at the cell edge and users near the base station have the same throughput, and the system allocates more resources to users with low C / I. The bit rate of all users in the cell is constant, and then calculate the required power value for each user, and compare the calculated total power with the maximum power of the base station. If the calculated power value is lower than the maximum power of the base station, the t...
