Description

Service scheduling method and device
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for service scheduling.
Background
In a Time Division Long Term Evolution (TD-LTE) broadband trunking system, a trunking base station supports both trunking group call services and public network voice and data services. Therefore, when performing service scheduling, a Medium Access Control (MAC) protocol entity of the trunking base station needs to consider concurrent scheduling of the trunking group call service and the LTE public network service.
In the TD-LTE public network base station, there are concurrent scheduling services such as paging, system information broadcast, voice service, data service, and the like.
In the TD-LTE trunked base station, besides paging, system information broadcast, voice service, and data service, trunked paging, trunked voice single call, trunked voice group call, and data service need to be supported.
Therefore, in the trunking base station, when the MAC protocol entity performs service scheduling, concurrent scheduling of services such as trunking group call and paging, system information broadcast, voice service, data service, trunking paging, trunking voice single call, and the like needs to be considered.
Because the trunking group calling only has downlink and does not have uplink, the TD-LTE trunking group calling does not have the concurrence of uplink scheduling. The types of services concurrent with the group call service are shown in table 1.
Table 1 service types concurrent with the downlink group call service
Figure BDA0000809573770000011
Figure BDA0000809573770000021
In the prior art, two types of terminals, namely a type 1 terminal and a type 2 terminal, are defined in a TD-LTE trunking system, and the search space types supported by the two types of terminals are as follows:
(1) the capability of a type 1 terminal for blind detection of a cluster Radio Network Temporary Identity (G-RNTI) in a Physical Downlink Control Channel (PDCCH) is defined as: cell Radio Network Temporary Identity (C-RNTI), Semi-Persistent Scheduling (SPS) C-RNTI and Temporary (Temporary) C-RNTI blind detection are supported in a PDCCH public search space and a UE (user equipment) private search space in a downlink subframe, and G-RNTI and SPS G-blind detection are supported in the PDCCH public search space and the group private search space at the same time.
(2) The capability of the type 2 terminal in PDCCH blind detection G-RNTI is defined as follows: C-RNTI, SPS C-RNTI and Temporary C-RNTI blind detection in a PDCCH public search space and a UE private search space is supported in a downlink subframe, G-RNTI and SPS G-RNTI blind detection in the PDCCH public search space is supported at the same time, but the G-RNTI and the SPS G-RNTI blind detection in a group private search space is not supported in a Radio Resource Control (RRC) connection state.
However, for the type 2 terminal, it is necessary to send a G-RNTI MAC Control Element (CE) to the base station in the message 3(Msg 3) through a random access procedure, or send G-RNTI MAC CE through a first uplink data/signaling packet after obtaining the G-RNTI of the cluster listened service. That is, the terminal type is reported, and the base station adopts a corresponding scheduling strategy according to whether the reporting message is received, and the mechanism will affect the performance of the cluster base station air interface. In the above process, that is, if the base station receives the report message, the base station determines that the terminal is the type 2 terminal, and adopts the scheduling policy corresponding to the type 2 terminal, and if the base station does not receive the report message, the base station adopts the scheduling policy corresponding to the type 1 terminal.
The trunking terminal reports the terminal type to the base station, and accordingly, when the trunking base station sends trunking paging to the trunking terminal, the trunking base station needs to start a timer to receive the MAC CE reported by the trunking terminal, so that the trunking base station adopts a corresponding scheduling strategy according to whether a reporting message is received or not.
Referring to fig. 1, a downlink scheduling scheme when a trunking base station issues trunking paging to a trunking terminal specifically includes:
step 101, an MAC protocol entity of a cluster base station receives a cluster paging message issued by a cluster core network.
Step 102, the cluster base station starts a timer T, where the time T is 300ms as an example.
Step 103, the cluster base station firstly schedules the group call of the cluster in the public search space, and then, the step 104 is carried out.
And 104, the cluster base station judges whether T is overtime, if so, the step 105 is executed, and otherwise, the step 106 is executed.
And 105, the cluster base station judges whether the cluster terminal reports the MAC CE, if so, the step 107 is executed, otherwise, the step 108 is executed.
And 106, the cluster base station continuously schedules the group call in a public search space.
And step 107, the cluster base station continues scheduling the group call in the public search space.
And step 108, the cluster base station schedules the group call in a public search space and a group-dedicated search space.
Therefore, when the trunking base station issues trunking paging, a timer needs to be started, and whether the trunking terminal reports the MAC CE is detected, which will also affect the processing performance of the TD-LTE trunking base station.
In addition, for a type 2 terminal, when the terminal is in an RRC connected state, if there is a group call to be scheduled, the cluster base station may only schedule the group call in a common search space, which may affect the performance of downlink scheduling in the TD-LTE cluster system.
To sum up, in the prior art, two types of terminals need to be defined in a concurrent service scheduling method for a cluster base station, and a cluster terminal needs to report a cluster terminal type to the cluster base station, that is, report an MAC CE to the cluster base station, and the cluster base station needs to start a timer after receiving a cluster page issued by a cluster core network, so as to detect whether the cluster terminal reports the MAC CE, and these mechanisms all affect the air interface performance of the cluster base station and the processing performance of the TD-LTE cluster base station. Meanwhile, for the type 2 terminal, when the terminal is in the RRC connected state, the cluster base station can only schedule the group call in the public search space, and will also affect the performance of downlink scheduling of the TD-LTE cluster system.

Detailed Description
The embodiment of the invention provides a method and a device for scheduling services, which are used for scheduling concurrent services by a cluster base station without defining a terminal type, thereby omitting the process that the cluster terminal needs to report the terminal type to the cluster base station and needs to start a timer to detect the MAC CE reported by the cluster terminal after the cluster base station sends a cluster paging to the cluster terminal, and improving the air interface performance of the cluster base station and the processing capacity of the cluster base station.
In the embodiment of the invention, two cluster terminal types do not need to be defined, and when the cluster base station determines that a plurality of services need to be scheduled, the cluster base station only needs to determine the type of each service and adopts a corresponding scheduling scheme according to the type of each service, so that the concurrent scheduling of the plurality of services can be realized. Therefore, the process that the cluster terminal reports the terminal type of the cluster terminal to the cluster base station and the cluster base station needs to start a timer to detect the MAC CE reported by the cluster terminal after sending the cluster paging to the cluster terminal when the cluster base station schedules the concurrent service in the prior art is omitted, and the processing performance of the cluster base station and the air interface performance of the cluster base station are improved.
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, an embodiment of the present invention provides a method for service scheduling, including:
s201, when determining that a plurality of services need to be scheduled, a cluster base station determines the type of each service and determines a scheduling search space corresponding to each type of service;
s202, the cluster base station schedules the type of service to be scheduled in a scheduling search space corresponding to the type of service.
When the trunking base station schedules the concurrent service, the concurrent service is specifically scheduled through an MAC protocol entity of the trunking base station.
In the embodiment of the invention, the services are divided into three types, namely, a first type service, a second type service and a third type service. Wherein the first type of traffic includes system information broadcast and/or trunking paging and/or non-trunking paging and/or random access, the second type of traffic includes TSRB traffic and/or TDRB traffic, and the third type of traffic includes SRB traffic and/or DRB traffic.
Of course, in actual operation, the services may be divided into more different types according to needs, and the services included in each type may also be different, which is not limited in the present invention.
Preferably, the determining, by the cluster base station, a type to which each service belongs and determining a scheduling search space corresponding to each type of service specifically includes:
when the service needing to be scheduled is a first type of service, the cluster base station determines that a scheduling search space corresponding to the first type of service is a public search space; alternatively, the first and second electrodes may be,
when the service needing to be scheduled is a second type of service, the cluster base station determines that a scheduling search space corresponding to the second type of service comprises a public search space and a group dedicated search space; alternatively, the first and second electrodes may be,
and when the service needing to be scheduled is a third type of service, the cluster base station determines that a scheduling search space corresponding to the third type of service comprises a public search space and a UE (user equipment) dedicated search space.
Preferably, the method for scheduling a service provided in the embodiment of the present invention further includes:
when the trunking paging and non-trunking paging of the same UE need to be scheduled in the first type service, the trunking base station schedules the trunking paging, information broadcasting and random access in the first type service in the public search space of the same subframe, and schedules the non-trunking paging in the public search space of another subframe;
or, the trunking base station schedules non-trunking paging, information broadcasting and random access in the first type service in the public search space of the same subframe, and schedules trunking paging in the public search space of another subframe.

In the embodiment of the present invention, the first type of service, the second type of service, and the third type of service may need to be scheduled at the same time, or only the first type of service and the second type of service need to be scheduled, or only the first type of service and the third type of service need to be scheduled, or only the second type of service and the third type of service need to be scheduled, or any of the first type of service, the second type of service, and the third type of service need to be scheduled. That is, the embodiment of the present invention does not limit the type of the concurrent service, and as long as there is a concurrent service that needs to be scheduled, the method provided by the embodiment of the present invention can implement scheduling of the concurrent service.
For the first type of service, the cluster base station adopts a dynamic scheduling mode when scheduling the search space for the type of service.
For example, when there is information broadcast, trunking paging, and random access service to be scheduled, the trunking base station dynamically schedules the information broadcast, trunking paging, and random access service in the common search space of the same subframe.
For the second type service and the third type service, the cluster base station adopts a dynamic scheduling or semi-persistent scheduling mode when scheduling the type service in the corresponding scheduling search space. In the specific implementation, dynamic scheduling or semi-persistent scheduling is adopted, which is determined according to the specific type of service, generally speaking, voice service is usually semi-persistent scheduling, and other services are dynamic scheduling.
For example, when the TSRB service and the TDRB service in the second type of service are voice services, the cluster base station uses a semi-persistent scheduling method for the services, otherwise, uses a dynamic scheduling method.
Preferably, the method for scheduling a service provided in the embodiment of the present invention further includes:
and when the scheduling search spaces corresponding to the services to be scheduled are the same, the cluster base station sequentially schedules in the scheduling search spaces according to the priority of the services to be scheduled.

By the service scheduling method provided by the embodiment of the invention, two types of terminals do not need to be defined, when the cluster base station determines that a plurality of services need to be scheduled, the type of each service is determined, and the scheduling search space corresponding to each type of service is determined according to the type of each service, so that the concurrent scheduling of the plurality of services is realized. Therefore, corresponding to the terminal side, when the terminal is in an RRC idle state, the terminal can blindly detect the G-RNTI or the SPS G-RNTI in the PDCCH common search space and the group dedicated search space; when the terminal is in an RRC connection state, the terminal can blindly detect G-RNTI or SPS G-RNTI in a PDCCH public search space and a group dedicated search space in the same downlink subframe, and blindly detect C-RNTI or SPS C-RNTI or Temporary C-RNTI in a PDCCH public search space and a UE dedicated search space in another downlink subframe.
A specific embodiment of the present invention will be given below.

Step 303, the trunking base station determines whether there is trunking paging to be scheduled, if yes, step 304 is executed, otherwise, step 305 is executed.
And step 304, the cluster base station dynamically schedules the cluster paging in the public search space of the current subframe, and then the step 305 is carried out.
Step 305, the cluster base station judges whether non-cluster paging needs to be scheduled, if so, step 306 is executed, otherwise, step 307 is executed.
Step 306, if the current subframe has the cluster paging scheduling of the same UE, the cluster base station dynamically schedules the non-cluster paging in the common search space of the subsequent subframe, otherwise, the cluster base station dynamically schedules the non-cluster paging in the common search space of the current subframe, and then step 307 is performed.
Here, that is, when there is trunking paging and non-trunking paging of the same UE to be scheduled, the trunking base station schedules the trunking paging and the non-trunking paging in different subframes, respectively. Preferably, in step 306 of the embodiment of the present invention, when there is trunking paging and non-trunking paging of the same UE to be scheduled, the trunking base station dynamically schedules the non-trunking paging in the common search space of the subsequent subframe, or the trunking base station dynamically schedules the trunking paging in the common search space of the subsequent subframe.
307, the cluster base station judges whether the random access needs to be scheduled, if so, the step 308 is executed, otherwise, the step 311 is executed.
Step 308, the cluster base station determines whether the public search space exceeds the maximum scheduling RNTI number N, if yes, step 309 is executed, otherwise, step 310 is executed.
And 309, dynamically scheduling the public search space of the subsequent subframe by the cluster base station.

Step 311, the cluster base station determines whether there is a cluster group call to be scheduled, if yes, step 312 is executed, otherwise, step 315 is executed.
Here, the cluster group call includes TSRB traffic and TDRB traffic.
Step 312, the cluster base station determines whether the public search space exceeds the maximum scheduling RNTI number N, if yes, step 313 is executed, otherwise, step 314 is executed.
Step 313, the cluster base station performs semi-persistent scheduling or dynamic scheduling on the cluster group call in the public search space and the group-dedicated search space of the subsequent subframe.
Step 314, the cluster base station performs semi-persistent scheduling or dynamic scheduling on the cluster group call in the public search space and the group-dedicated search space of the current subframe, and then the step 315 is carried out.
Step 315, the cluster base station judges whether there is SRB service and/or DRB service to be scheduled, if yes, step 316 is executed, otherwise, scheduling is ended.
In step 316, the cluster base station determines whether the common search space exceeds the maximum scheduling RNTI number N, if yes, step 317 is executed, otherwise, step 318 is executed.
Step 318, if the cluster group call of the same UE needs to be scheduled in the current subframe, the cluster base station performs semi-persistent scheduling or dynamic scheduling on the SRB service and/or the DRB service in the common search space of the subsequent subframe and the UE-dedicated search space, otherwise, performs semi-persistent scheduling or dynamic scheduling on the SRB service and/or the DRB service in the common search space of the current subframe and the UE-dedicated search space, and then the whole scheduling is finished.
Here, that is, when there is a trunking group call and SRB and DRB service of the same UE to be scheduled, the trunking base station schedules the trunking group call and the SRB and DRB service in different subframes, respectively, that is, the SRB and DRB service are scheduled in a search space of the same subframe, and the trunking group call is scheduled in a search space of another subframe. Preferably, in step 218 of the embodiment of the present invention, when there is a cluster group call, an SRB service, and a DRB service of the same UE to be scheduled, the cluster base station schedules the SRB service and the DRB service in a search space of a subsequent subframe, and certainly, the cluster group call may also schedule the search space of the subsequent subframe.
