The invention is described below in conjunction with the scenario embodiments.
In practical application, subscription information of the UE is stored in the HSS, the UE initiates a service request to an access and mobility management function (AMF), and the AMF establishes a PDU session (PDU session) for the UE according to the subscription information. And the AMF sends a QoS parameter (QoS Profile) to the gNB base station, and the QoS parameter carries acceleration indication information. After receiving the acceleration indication information, if there is a spare downlink resource, the gNB preferentially allocates the resource to the user.
Here, the subscription information of the UE indicates that the related service of the UE needs to be accelerated.
Here, the downlink acceleration indicating method may include:
example one
When downlink scheduling is carried out by the gNB, adding 'starting acceleration indication' and 'stopping acceleration indication' in a reserved bit of a PDCP layer for a Data Radio Bearer (DRB) of service to be accelerated of the UE to be accelerated; the MAC layer of the gNB preferentially schedules packets between the 'start acceleration indication' and the 'stop acceleration indication'.
For example: the first data packet carries the start acceleration indication, the nth data packet carries the stop acceleration indication, and the gNB schedules the first to nth data packets preferentially.
The indication information may also be carried in an SDAP packet, or a PDCP packet (e.g., a PDU of a PDCP), or an RLC packet.
Example two
When the AMF establishes the DRB for the gNB, the AMF may indicate the DRB 'acceleration indication' to the gNB, so that when the MAC layer of the gNB has extra spare resources, resources are preferentially allocated to the user corresponding to the DRB.
In the above embodiment, during downlink transmission, the main role of the acceleration indication information is cross-layer interaction inside the base station, because all UE transmissions share PDSCH resources, so that the MAC layer can identify which data packet has higher priority and needs to be transmitted preferentially during downlink scheduling.
The uplink acceleration indication method can comprise the following steps:
EXAMPLE III
During uplink scheduling, for a single user, the base station configures the highest logical channel priority for the service to be accelerated of the UE according to the acceleration indication information in the QoS parameter, so as to ensure that the UE can preferentially schedule the logical channel corresponding to the service during uplink transmission.
Example four
In uplink scheduling, for the case of multiple users, in order to ensure that the user to be accelerated can obtain a higher scheduling opportunity among the multiple users, the following method is adopted:
the method comprises the following steps: UE sends Service Request message (Service Request) to network side, the message attaches acceleration indication Request information, which is used to indicate the Service needs acceleration;
step two: after receiving the service request message, the network sends DRB establishment configuration information to the UE;
the configuration information includes at least one of the following:
'acceleration grant' information (for indicating that the terminal is allowed to perform traffic acceleration);
special SR configuration information (configuring scheduling request SR resources which are specially used for the service to be accelerated and apply for uplink grant for UE);
dedicated random access resources (dedicated random access resources including beam recovery).
Here, the role of the network allocating a specific (dedicated) SR resource for the service to the UE is that the network receives the SR resource to preferentially respond to the scheduling request of the UE and preferentially allocates an uplink scheduling grant (UL grant) to the UE.
Step three: after receiving the UL grant, the UE carries the acceleration indication information in BSR report through a media access control element (MAC CE), and the network preferentially allocates uplink resources to ensure the rate. And if the network has spare uplink resources, allocating the spare uplink resources to the UE.
Here, if there are multiple UEs reporting the acceleration information, the network evenly allocates the vacant uplink resources for the multiple UEs.
EXAMPLE five
In the fourth embodiment, for the case of multiple users, after the network receives the service request message, the network configures a corresponding acceleration indicator code for each service to be accelerated of each terminal that sends the service request message; the acceleration indication code is used for distinguishing acceleration priorities of different terminals and different services;
for example: the acceleration indicator may be: 1. 2, 3, …, etc., a 1 may indicate that the traffic to be accelerated is the highest priority, the higher the number, the lower the priority.
Then receiving the acceleration indication code sent by each terminal; and allocating uplink transmission resources with corresponding priorities to each service to be accelerated of each terminal.
EXAMPLE six
The network side determines each service to be accelerated of each terminal to be accelerated based on the acceleration indication information carried in the QoS parameters;
respectively configuring corresponding acceleration indication codes for each service to be accelerated of each terminal; each service to be accelerated of each terminal is provided with a corresponding acceleration indication code, the acceleration indication code is used for distinguishing the terminal to be accelerated and the service to be accelerated at a network side, and the acceleration indication code is reported through an MAC CE when the terminal applies for a BSR;
the network side distinguishes different terminals and acceleration priorities of different services according to the acceleration indication codes sent by each terminal;
and allocating uplink transmission resources with corresponding priorities to each service to be accelerated of each terminal.
The embodiment of the invention can realize a refined scheduling scheme, schedule different data packets in the same service of the same terminal, and schedule different services of different terminals according to the priority, thereby providing excellent service experience for users.
For example: when several terminals are operating the royal glory and the royal glory is contracted with the operator as the acceleration service, the UE with 500 yuan of monthly fee and the UE with 40 yuan can be distinguished by the acceleration indication code even if the QCI is 9. Since the total number of QCIs is limited, and the number of services to be accelerated and UEs to be accelerated is large, if the services are distinguished only by the QCIs according to the existing scheme, only the number of QCIs 9, which is obviously insufficient.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
