Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Step shown in the flowchart of the accompanying drawings can be in a computer system such as a set of computer executable instructions
It executes, although also, logical order is shown in flow charts, and it in some cases, can be to be different from herein suitable
Sequence executes shown or described step.
A kind of cut-in method is present embodiments provided, Fig. 2 is the process signal of cut-in method according to an embodiment of the present invention
Figure one, as shown in Fig. 2, the process includes the following steps:
Step S202 obtains the configuration information of FMO from base station；
Step S204 is determined according to the identification information of configuration information and UE for connecing before executing to the forward direction of access procedure
Enter the period；
Step S206, according to preceding to the access period, to access procedure before executing.
Through the above steps, UE can be after the configuration information from base station acquisition FMO, according to the mark of configuration information and UE
Know information, determines the forward direction access period of the UE, and preceding to access according to determining forward direction access period progress.Compared to correlation
To the scheme of access before the period except FMO can carry out in technology, above-mentioned steps according to the mark of UE due to that can believe
Breath configures different forward directions for different UE and accesses the period, thus for UE or base station, the corresponding forward direction of some UE connects
It is known for entering the period, and the total length of the preceding period that can be much smaller than except from FMO to the access period.In such case
Under, UE, which only needs to access the period in known forward direction, to be opened before radio frequency executes to access procedure, thus to accessing before solving
The more problem of the longer radio frequency power consumption for leading to UE of journey has reached UE economize on electricity to save the electric quantity consumption of the radio frequency of UE
Effect.
Wherein, the identification information of UE is the cell-radio network temporary marker that the UE is distributed in base station.
Preferably, configuration information is obtained from base station by system message or resource reallocation message.Wherein, which disappears
Breath refers to the system message of cell where UE, which is to obtain at the persistent district UE from the cell of base station, can be with
The resource or configuration information of cell can be in UE by carrying the configuration information of FMO in system message where being used to indicate UE
The configuration information of FMO is obtained when persistent district；The resource that the resource reallocation message is used to indicate UE resource reconfigures, in cell
Distributing to base station when the resource of UE changes can notify that UE be configured accordingly by the resource reallocation message, therefore,
By carrying the configuration information of FMO in resource reallocation message, the configuration of FMO can be changed, dynamically so as to dynamically adjust
