It is rapid:
S111: sending SPS to UE and configure message, and it includes at least two SPS information that wherein the SPS, which configures message,.
S112: the operation requests for corresponding SPS from UE are received.
Operation requests include activation request and/or release request.Operation requests are in addition to indicating action type (activation/release)
Except, also it should indicate which SPS (s) be directed to.UE can send operation requests to base station according to the state of itself.
For example, UE can choose whether to enable certain service (example according to the state of itself in car networking (V2X)
Such as speed monitoring).If enabling the service, activation request is sent to activate corresponding SPS, starts periodically to upload the service
Status data (real-time speed).When the variation of UE oneself state (such as parking), it can choose and deactivate the service, sent out to base station
It send release request to discharge corresponding SPS, and stops uploading status data.
It should be noted that the transmission of release request may include dominant and recessive two types.Dominance type refers to UE
It directly transmits and releases order to base station, and recessive type refers to UE in a manner of stopping using SPS resource to send data to base station
To propose release request.It is that SPS resource indicates to be discharged by which SPS.Release request for recessive type, base station needs
UE is not received uses the read-around ratio of the data of corresponding SPS resource transmission and the size of preset threshold.When this continuous time
Number is greater than the preset threshold, then judgement has received the release request of recessive type.
