Description
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a storage medium for enabling a user plane optimization function.
Background
For NB-IOT (Narrow Band Internet of Things) terminals, a User plane optimization scheme is introduced, and a new defined RRC (Radio Resource Control) connection suspension and recovery procedure is used to enable a UE (User Equipment) to migrate from an EMM-IDLE (Evolved Packet System Mobility Management-IDLE) state to an EMM-CONNECTED (Evolved Packet System Mobility Management-CONNECTED) state without initiating a service request procedure (e.g., service request) and to change the RRC state from IDLE to CONNECTED, thereby saving related air resources and signaling overhead.
When the data transmission between the UE and the network is finished, the eNB sends an RRC connection release message to the UE, wherein the RRC connection release message contains Resume id information, and meanwhile, the eNB stores the context information of the RRC access layer of the UE and informs the MME of keeping the information about the UE. And when the UE has data to send next time, initiating an RRC connection Resume request process, wherein the message carries a Resume id, the eNB finds the context of the UE through the Resume id, restores the RRCconnection Setup message and restores the RRC connection.
In an application scenario of internet of things universal interconnection, an eNB (base station) needs to serve a large number of NB-IOT terminals, and if a user plane optimization scheme is enabled for each NB-IOT terminal accessing a network, that is, after data transmission for each NB-IOT terminal is completed, the UE is instructed to enter RRC-idle and ECM-idle states, but connection context information of the UE is retained in the eNB and an MME, so that the overhead of maintaining resources by the eNB and the MME is increased.

Detailed Description
In order to reduce the overhead of maintaining resources for maintaining the context information of the terminal connection by the network side device, embodiments of the present invention provide a method, an apparatus, and a storage medium for enabling user plane optimization, so as to assist the network side in determining whether the context information of the terminal connection needs to be maintained.
The method for enabling the user plane optimization function provided by the embodiment of the invention can be applied to the user plane optimization aiming at the terminal equipment, in particular to the user plane optimization aiming at the NB-IOT terminal. It should be noted that the user plane optimization function according to the embodiment of the present invention is to release the RRC connection between the terminal and the base station, and not perform channel synchronization and uplink and downlink reference signal transmission any more, but reserve context information for the terminal at the base station side, so as to allow the user to initiate a connection message (RRC connection resume) process without creating an RRC connection when the user has data transmission next time.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
The inventors found that in the current protocol, how the eNB (base station) determines whether to adopt the user plane optimization scheme for the terminal and the duration for which the eNB and MME should keep the context information for the terminal are not defined. The eNB also has no information to assist in determining whether to initiate user plane optimization for the terminal, and the eNB only knows whether the UE has capability information to support user plane optimization.
Therefore, the method for enabling user plane optimization according to the embodiment of the present invention can provide more information of the terminal bearer service to the eNB, so that the eNB can make a more intelligent decision, and after data transmission is completed, whether to suspend the state of the terminal is performed to resume RRC (radio resource control) linking quickly in the following.
In the embodiment of the invention, the terminal is divided into a plurality of levels according to the service initiation time frequency of the terminal and the mobility of the terminal, and the terminal service initiation interval time frequency information and/or the terminal mobility information are provided for the base station to make a decision whether to enable a user plane optimization scheme aiming at the terminal.
As shown in fig. 1, which is a schematic implementation flow diagram of a method for enabling user plane optimization according to an embodiment of the present invention, the method may include the following steps:
and S11, receiving the terminal attribute information.
Wherein the terminal attribute information includes at least one of: the service initiation interval frequency information of the terminal and the mobile state information of the terminal.
Specifically, the service initiation interval frequency of the terminal may be defined by the device or the operator, for example, N levels, where each level corresponds to a certain frequency range. For example, according to the data service initiation frequency, the number of times of initiating a service per day is defined as 3 levels:
service class 0: more than 30 times/day (e.g., wearable device).
Service class 1: 30 times/day-1 times/day (e.g., security, car networking).
Service class 2: 1 time/day-once initiated for a longer time (such as water and electricity meter reading and the like).
And according to the moving state of the NB-IOT terminal, the NB-IOT terminal can be divided into the following 2 levels:
movement attribute 0: and (5) fixing the table class.
Movement attribute 1: low speed sports (car networking, wearable device).
It should be understood that the above description is for illustration only, and in particular implementation, the attribute types can be divided into more according to actual needs.
And S12, if the user plane optimization function is determined to be enabled for the terminal according to the received terminal attribute information, sending a message to inform the terminal that the user plane optimization function is enabled.
In specific implementation, the network side device may determine whether to enable the user plane optimization function for the terminal according to the received terminal attribute information. Specifically, whether the user plane optimization function needs to be enabled, that is, whether connection context information needs to be reserved for the terminal, may be determined according to the attribute level corresponding to the terminal. For example, for the data service frequency, connection context information of terminals with service levels 0 and 1 may be retained, for the mobile state information, connection context information of a terminal with a mobile attribute of 0 may be retained, and the like. If the network side determines that the user plane optimization needs to be enabled, a message is sent to notify the terminal of enabling the user plane optimization function, for example, the network side may notify the terminal of enabling the user plane optimization function by using RRC (radio resource control) signaling.
In a specific implementation, step S11 may be implemented in any of the following manners:
in a first embodiment, terminal attribute information of a terminal notified by a mobility management network element is received.
In one embodiment, the terminal attribute information may be sent to the mobility management element for the HSS (home subscription server).
In this embodiment, the HSS may add terminal attribute information, such as service initiation interval frequency information of the terminal and mobility state information of the terminal, to the user subscription information.
In an Attach procedure or a TAU (tracking area Update) procedure, the HSS sends the terminal attribute information to the mobility management element, for example, the HSS may send the terminal attribute information to the mobility management element using a location Update acknowledge message (Update location ack), the mobility management element notifies the base station of the received terminal attribute information, and for example, the mobility management element may send the terminal attribute information to the base station using an Initial Context setup request (Initial Context setup request) or a Downlink non-access stratum transport and Attach accept (Downlink NAS transport with Attach accept) message.
In another embodiment, the terminal attribute information may be sent by the terminal to the mobility management network element. In specific implementation, the non-access stratum of the terminal determines terminal attribute information such as service initiation interval frequency information of the terminal and mobility state information of the terminal according to service information of the internet of things currently carried by the terminal, and can send the terminal attribute information to a mobility management network element by using non-access stratum (NAS) signaling. For example, in the process of triggering the Service Request by the terminal, the terminal sends the terminal attribute information to the mobility management element through the base station by using a Service Request message (NAS: Service Request), and the mobility management element sends the obtained terminal attribute information to the base station through an Initial Context Setup Request message (S1-AP: Initial Context Setup Request).
In a second embodiment, terminal attribute information reported by a terminal is received.
For example, receiving terminal attribute information reported by a terminal through RRC (radio resource control) signaling; or receiving terminal attribute information carried in a Packet Data Convergence Protocol (PDCP) Data conversion protocol Data message by the terminal; or receiving terminal attribute information carried by the terminal in an RLC (Radio Link Control, Radio Link layer Control protocol) data message; or receiving terminal attribute information carried by the terminal in a MAC (Medium Access Control) data packet.
In specific implementation, a non-access layer of a terminal determines terminal attribute information such AS service initiation interval frequency information of the terminal and mobile state information of the terminal according to service information of the internet of things currently carried by the terminal, and sends the information to an RRC (radio resource control) of the terminal through interlayer interaction between an NAS (network attached storage) and an AS (application server) of UE (user equipment); during the RRC connection establishment, the terminal reports the terminal attribute information to the base station using an RRC connection request message or an RRC connection complete message.
It should be noted that the mobility management network element according to the embodiment of the present invention may include a Mobility Management Entity (MME) for fourth-generation wireless communication, a mobility management function entity (AMF) for fifth-generation wireless communication, and the like.
