Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. The terms "upload," "configure," "activate," and the like are used herein for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

VoLTE is an end-to-end voice solution under all IP (Internet Protocol, interconnection Protocol between networks) over 4G network architecture. Compared with the traditional 2G/3G voice communication quality, the quality can be improved by more than 40 percent; compared with the conventional 2G (2-Generation wireless telephone technology, second-Generation mobile phone communication technical specification)/3G (3rd-Generation, third-Generation mobile communication technology) voice call access delay (waiting time after dialing), the voice call access delay can be reduced by 50% (VoLTE is about 2s approximately, and 2G is about 7s approximately); compared with the traditional 2G/3G voice call drop rate, the 2G/3G voice call drop rate occurs sometimes, and the drop rate of VoLTE approaches zero.

For VoLTE voice services, there is typically one packet every 20ms, representing a periodic transmission. By adopting a common dynamic Scheduling mechanism, Control information needs to be sent through a Physical Downlink Control Channel (PDCCH) every 20ms to update a time-frequency resource or MCS, which may cause great PDCCH resource consumption and seriously affect user capacity, and at this time, a new technique is needed to reduce PDCCH overhead of VoLTE service, so that a Semi-Persistent Scheduling (SPS) technique is introduced. The SPS technology can ensure that a base station sends a control message to a terminal through the PDCCH during a call, only needs to allocate fixed resources once, and does not need to request resource allocation again through the PDCCH before the call is finished or the resources are released, so that the PDCCH overhead is greatly saved, signaling interaction information with a bottom layer is reduced, and the user capacity and the system performance are improved.

However, the introduction of SPS technology brings new challenges to the scheduling mechanism of LTE system, and for example, the determination of activation and deactivation of SPS has become one of the most urgent key technologies at present. Therefore, the research on the efficient uplink semi-persistent scheduling mechanism has strong practical significance.

Under the mixed scene of coexistence of VoLTE service data and other service data, especially for uplink data, a plurality of services share one logic channel group, and misjudgment of activation or reactivation of an uplink SPS service by a base station is seriously influenced, so that PDCCH overhead and resource waste are increased, and user capacity is influenced.

In order to solve the above problems, the present invention provides an uplink semi-persistent scheduling method, apparatus and system, which can reduce PDCCH overhead, remove interference of other service data to a base station, more accurately determine activation/reactivation time, and increase user capacity.

specifically, SPS configuration information of the independent bearer VoLTE service is sent to the external UE, the external UE is informed to upload the VoLTE service data only in an SPS scheduling mode, and the UE side and the base station side independently output SPS bearers;

preferably, the base station side sends the SPS configuration information to the external UE through the data sending module;

step S120, when the SPS configuration is activated, the SPS scheduling resource is distributed to the external UE, and an SPS configuration activation instruction is sent to the external UE; and the SPS configuration activating instruction is used for indicating the external UE to stop reporting the VoLTE service data buffer report and preferentially uploading the VoLTE service data when the scheduling period of the SPS scheduling arrives.

Specifically, when the SPS configuration is activated, the SPS scheduling resources are distributed to the external UE from the scheduling resources, and an SPS configuration activation instruction is sent to the external UE; the external UE performs SPS configuration activation according to the SPS configuration activation instruction; moreover, after the SPS configuration is activated, the external UE does not report a data buffer report (belonging to a VoLTE service data buffer report) of the VoLTE service, so that the signaling interaction between the UE side and the base station side can be reduced, and the PDCCH overhead can be saved; and preferentially uploading VoLTE service data at the SPS scheduling period;

it is noted that SPS scheduling resources may be used for transmission of SPS data; specifically, the allocation can be performed through the base station side, such as frequency, frequency band, and the like;

after receiving the SPS configuration activating command, the UE does not report a data buffer report of the VoLTE service any more, and only sends the data of the VoLTE service at the SPS scheduling period; if the data of other services exist, the data of the VoLTE service is preferentially sent at the SPS scheduling period, and the data of other loads stops being sent at this time.

Preferably, when activating the SPS configuration, the base station side may allocate SPS scheduling resources to the external UE, and send an SPS configuration activation instruction to the external UE; specifically, an SPS configuration process can be started according to the VoLTE service characteristics, and an SPS configuration management unit and an SPS time delay management unit are notified; the SPS configuration management unit manages SPS configuration information and informs the SPS judgment management unit to judge a subsequent process; and when the SPS decision management decision selects the SPS activation, the UE is informed of synchronously activating the SPS configuration through the data transmission module.

preferably, the SPS decision management decision at the base station side selects an SPS activation phase, notifies an SPS delay management unit, and counts the delay condition of the VoLTE service; further, the determination may be made based on the round trip of the application layer packet.

Step S224, when the time delay is greater than or equal to the preset time value, the SPS configuration is reactivated, the SPS scheduling resource is distributed to the external UE, and an SPS configuration activating instruction is sent to the external UE.

Specifically, when the time delay of the VoLTE service data is greater than or equal to a preset time value, the SPS configuration needs to be activated again, SPS scheduling resources are allocated to the external UE, and an SPS configuration instruction is sent to the external UE, so that the external UE has more SPS scheduling resources to upload the VoLTE service data, the time delay is reduced, and the voice effect is guaranteed;

it should be noted that the preset time value may be set according to a requirement, and optionally, the preset time value may be set to 200ms (milliseconds);

In an embodiment, as shown in fig. 12, fig. 12 is a second schematic flowchart of a UE side of an uplink semi-persistent scheduling method in an embodiment, where the step of preferentially uploading VoLTE service data when a scheduling period of SPS scheduling arrives further includes the following steps:

step S830, when receiving the retransmission instruction, retransmitting VoLTE service data according to the retransmission instruction;

step 840, when the retransmission instruction is received and the next scheduling period comes, the VoLTE service data is uploaded.

Specifically, when a retransmission instruction sent by a base station side is received, the UE side retransmits VoLTE service data of the current scheduling period according to the retransmission instruction; if a retransmission instruction sent by the base station side is received and the next scheduling period time is reached, the normal scheduling period is preferentially selected for transmission, VoLTE service data is uploaded, and retransmission VoLTE service data is abandoned, so that the time delay is reduced, bandwidth resources are reasonably utilized, and the user capacity is increased;

in one embodiment, as shown in fig. 12, further includes:

step S850, when the SPS configuration deactivation instruction is received, uploading of VoLTE service data is stopped according to the SPS configuration deactivation instruction;

and step S860, when receiving the SPS de-configuration information for canceling the independent bearing VoLTE service, stopping adopting SPS scheduling to upload VoLTE service data, and releasing the VoLTE service.

Specifically, when receiving an SPS configuration deactivation instruction sent by a base station side, a UE side does not upload VoLTE service data any more; when the UE side receives SPS de-configuration information which is sent by the base station side and cancels the independent load VoLTE service; and releasing the VoLTE service and the SPS scheduling according to the SPS de-configuration information, stopping uploading VoLTE service data by adopting the SPS scheduling, ending the SPS scheduling process and ending the call.

It should be understood that although the various steps in the flow charts of fig. 5-12 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 5-12 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
