Problems solved by technology

[0007] At the same time, unlike public network services, there are more uplink services in private network services; therefore, the shortage of scheduling methods in public networks is very obvious
At the same time, there are also uplink-only lecturers and downlink-only groups in the private network, which further increases the complexity of implementation and cannot directly apply the existing scheduling methods in the public network

Embodiment Construction

[0028] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below.

[0029] As mentioned in the background technology, in the current scheduling method of the public network system, the uplink scheduling is performed after the downlink scheduling is completed, so the uplink scheduling time is often preempted, resulting in the user not being uplink and causing the user to be released, which affects the user's call quality.

[0030] In order to overcome the above problems, it is possible to limit the time for downlink scheduling, specify the cut-off time for downlink scheduling, stop downlink scheduling when the cut-off time for downlink scheduling is reached, and perform uplink scheduling. However, if this method is used, when there are a large number of downlink users but no uplink users in the system, the downlink will face insufficient scheduling, and the uplink scheduling...

Abstract

The invention discloses an SPS service scheduling method. The method comprises the following steps: calculating scheduling time of an uplink SPS user already activated in a current TTI, and pre-estimating resource distribution time of downlink scheduling processing; before activation scheduling is carried out on any one downlink SPS user, distributing reserved time for the scheduling of the uplink SPS user already activated in the current TTI and the resource distribution of the downlink scheduling processing, and according to periodical common scheduling and random access scheduling conditions of the current TTI, determining whether to carry out activation on the any one downlink SPS user. By using the SPS service scheduling method, the scheduling of SPS service can be balanced, and the scheduling performance is improved.

Description

technical field [0001] The present application relates to scheduling technology in communication systems, in particular to a scheduling method for SPS services. Background technique [0002] In LTE, both uplink and downlink grants are sent to terminals through downlink control channels; whether it is TDD or FDD, uplink scheduling must be completed in the subframe of downlink scheduling, and the terminal is notified in the downlink subframe. Because the uplink and downlink scheduling needs to be completed simultaneously within one TTI, the allocation of uplink and downlink scheduling time has to be considered. [0003] In the existing public network scheduling method, the uplink scheduling is performed after the downlink scheduling is completed, and each scheduling is required to be completed within 1ms (once the scheduling time exceeds the limit, the scheduling made by this TTI will not be performed or directly discarded), and the 1ms When the scheduling time is up, schedul...
