Technical Field

The present invention relates to the technology of internet of things, and in particular, to a wireless control method and apparatus, a base station, and a storage medium.

Background

If the APN is unreasonable, the user cannot pass the authentication process of the network service provider, thereby resulting in the inability to surf the internet. The APN names are various, for example, the names of access points of chinese mobile are cmnet and cmwap, different APNs point to different Packet Data Networks (PDN), for example, the cmnet points to the Internet (Internet), that is, chinese mobile users with the APN set as the cmnet will be able to access the Internet.

A user accesses a narrowband Internet of Things (NB-IoT) network of a mobile operator through a Subscriber Identity Module (SIM) card, and meanwhile, the SIM card and a Home Subscriber Server (HSS) of a core network store the same APN information. Then, in the process of attaching the user, a Mobility Management Entity (MME) acquires the APN information from the terminal, and authenticates with the APN as one of the authentication information.

In a Long Term Evolution (LTE) system, mobile phone users have various service types, but all are internet services, and therefore, the mobile phone users are marked by an APN representing an internet PDN in a unified manner.

Detailed Description

In an NB-IoT system, the types of terminals/service types of the internet of things (in the internet of things, terminals and service types are often in one-to-one correspondence) are very rich, for example, meter, street lamps, and bicycles, and different terminal/service types are in different demands, for example, the meter terminal and the bicycle terminal have very high requirements on power consumption, and street lamps are not sensitive to power consumption due to power supply; the single traffic is sensitive to time delay, but the street lamp traffic can tolerate a certain degree of time delay. Therefore, in the NB-IoT system, on one hand, for the network side, different terminals have different characteristics in terms of terminal characteristics, service characteristics, and requirement characteristics, and the network side provides the same service for the terminal at present and does not well utilize the different characteristics to optimize the network and improve the performance of the network; for example, terminals with different delays can be divided, a network with low delay is provided for a terminal with sensitive delay, and a network with slightly poor delay is provided for a terminal with insensitive delay. On the other hand, it is necessary to configure different APNs for different terminals, or service types, or terminals/services having the same type of requirements (such as power consumption, delay, rate, etc.), so that the network can perform some customized operations on a certain terminal/service type through the APN, thereby improving user experience.

For existing NB-IoT systems, there are some drawbacks and deficiencies:

for the current system, the eNB does not know the terminal characteristics, the service characteristics, and the demand characteristics of the current UE, and therefore cannot accurately perform wireless control. For example, some UE-specific parameters (i.e., UE-specific parameters, also called UE-specific type parameters), such as parameters affecting power consumption (UE inactivity timer duration, datainactivity timer, rai-Activation), parameters affecting power control (p0-UE-NPUSCH-r13), parameters affecting connection re-establishment after link failure (rlf-timers), parameters affecting data transmission rate (twosharq-processscconfigure), parameters affecting connection state power consumption and latency (C-DRX), etc. The configuration of these parameters often requires some knowledge of the terminal type, or traffic type, or demand type based on the eNB. Currently, the eNB cannot know the above information, and therefore, the eNB cannot reasonably configure the above UE-specific parameters.

The technical solution of the present invention is further elaborated below with reference to the drawings and the embodiments.

From the above, it can be seen that the HSS can complete the update of the mapping relationship table between the MME and the base station by actively sending the synchronization message.

This embodiment provides a wireless control method, which is applicable to a method for determining, on a base station side, a terminal characteristic, a service characteristic, and a requirement characteristic based on an APN type, and further may implement wireless control, for example, configuring a UE-specific parameter, performing a scheduling decision, and the like, where fig. 3A is a schematic diagram of an implementation flow of the wireless control method according to an embodiment of the present invention, and as shown in fig. 3A, the method includes:

step S301, a base station maintains a mapping relation table of APN and terminal attributes;

wherein the terminal attributes include at least one of: a terminal characteristic (or terminal characteristic), a service characteristic (or service characteristic), a demand characteristic (or demand characteristic); the terminal characteristics include at least one of mobility, power supply, battery capacity and the like, the service characteristics include at least one of periodicity, service period, service model (traffic profile), service duration, communication period (e.g., 10:00 to 11:00 in the morning or evening of every monday) and the like, and the requirement characteristics include at least one of power consumption requirement and delay requirement. The table in this step is maintained in both the MME and the HSS, and addition, modification, and deletion of any mapping relationship in the table can only be operated by the HSS, and after any addition, modification, and deletion operation, the HSS needs to notify the MME of the operation content.

In the implementation, referring to table 3A, the mapping relationship table may be about the APN and the terminal characteristics (mobility, power supply, battery capacity, etc.); referring to table 3B, the mapping relationship table may also be about between APNs and traffic characteristics; referring to table 3C, the mapping relationship table may also be for between APNs and demand characteristics; referring to table 3D, the mapping relationship table may also be for APN and terminal characteristics, service characteristics, and demand characteristics. In other embodiments, the mapping relation table may also relate to APNs and terminal characteristics and service characteristics; the mapping relation table can also relate to APN, terminal characteristics and requirement characteristics; the mapping relation table can also be about APN and service characteristics and requirement characteristics; that is, tables 3A, 3B, and 3C are combined in pairs, or are part of Table 3D.

In other words, the mapping table may be a mapping table of APNs and terminal characteristics (mobility, power supply, battery capacity, etc.), and/or service characteristics (periodic service, service period, service model, communication time period, service duration, etc.), and/or requirement characteristics (power consumption requirement, delay requirement, etc.). Through the APN, the base station can index to obtain the terminal characteristics, and/or the service characteristics, and/or the demand characteristics corresponding to the APN.

Step S302, when a base station establishes UE context information, APN information of the UE is obtained from a core network;

for example, when the base station establishes the UE context Information, the base station acquires the APN Information of the UE from the core network through a related S1AP message, such as a UE Information Transfer message, for example, acquires the APN Information of the UE to the MME, and acquires the terminal feature, and/or the service feature, and/or the requirement feature of the UE based on the mapping relationship table in step S301.

Step S303, based on the mapping relation table, the base station acquires the terminal characteristics, and/or the service characteristics, and/or the demand characteristics of the UE;

step S304, if the APN value obtained by the base station is not in the table in step S301, the base station requests the MME to obtain the terminal feature, and/or the service feature, and/or the requirement feature corresponding to the APN through the message S1AP, and adds the mapping relationship to the mapping relationship table in step S301.

Step S305, based on steps S302 and S303, the base station obtains the terminal characteristics, and/or the service characteristics, and/or the requirement characteristics of the UE, and based on the judgment, the base station can perform wireless control, such as configuring some UE-specific parameters; these parameters may be maintained by the eNB or may be configured by the eNB to the UE; for example, more reasonable scheduling is achieved. The parameter scheduling includes, but is not limited to, parameters affecting power consumption (UE inactivity timer duration, datainactivity timer, rai-Activation), parameters affecting power control (p0-UE-NPUSCH-r13), parameters affecting connection re-establishment after link failure (rlf-timersandconnections), parameters affecting data transmission rate (twoHARQ-processesconfigug), parameters affecting power consumption and latency (C-DRX), and the like.

In other embodiments, the base station may also configure the UE-specific parameter of the terminal in combination with the APN, the QoS, the UE radio capability, and other information.

TABLE 3A mapping relationship Table between APN and terminal characteristics

TABLE 3B mapping relationship Table between APN and service characteristics

Wherein: unidirectional transmission: unidirectional packet transmission (UL or DL) (Single-transmission: Single packet transmission (UL or DL)); bidirectional transmission: bidirectional packet transmission (Dual-transmission: Dual packet transmission (UL with subsequent DL, or DL with subsequent UL)); multiplexing transmission: multiple-packet transmission (Multiple-packets transmission).

TABLE 3C Table of mapping relationships between APNs and demand characteristics

Table 3D table of mapping relationships between APNs and terminal characteristics, service characteristics and demand characteristics

The base station maintains a mapping table of APNs and terminal characteristics, and/or traffic characteristics, and/or demand characteristics, such as the following table 3D:

the base station acquires the APN Information from the MME, such as through a UE Information Transfer message, or other S1AP message. And if the APN is not stored in the local APN mapping relation table of the base station, the base station requests the MME for the terminal characteristics, and/or the service characteristics, and/or the requirement characteristics corresponding to the unknown APN, and stores the terminal characteristics, and/or the service characteristics, and/or the requirement characteristics in the local APN mapping relation table of the base station.

If the APN is not stored in the MME, the MME requests the HSS for the terminal characteristic, and/or the service characteristic, and/or the requirement characteristic corresponding to the unknown APN, then the terminal characteristic, and/or the service characteristic, and/or the requirement characteristic are stored in a local APN mapping relation table, and the terminal characteristic, and/or the service characteristic, and/or the requirement characteristic are fed back to the base station.

And the base station acquires the corresponding terminal characteristics, and/or service characteristics, and/or demand characteristics according to the APN mapping relation table, and configures the UE-specific parameters based on the information.

Fig. 3B is a schematic diagram of an implementation process of maintaining and updating a mapping relationship table according to an embodiment of the present invention, and as shown in fig. 3B, the process includes:

step S311, the base station maintains a mapping relation table;

the mapping relation table reflects the mapping relation between the APN and the terminal, for example, the mapping relation table is used for representing the mapping relation between the APN and the terminal characteristic, and/or the service characteristic, and/or the requirement characteristic;

step S312, the base station requests the MME for terminal characteristics, service characteristics and/or demand characteristics corresponding to unknown APN;

when the base station establishes UE context information, APN information of the UE is acquired from a core network; acquiring terminal characteristics, or/and service characteristics, or/and demand characteristics of the UE based on the mapping relation table locally maintained by the base station; if the APN value obtained by the base station is not in the table of step S301, the base station requests the MME to obtain a terminal feature, and/or a service feature, and/or a requirement feature corresponding to the APN;

step S313, the MME feeds back to the base station;

here, the MME locally maintains the mapping table, and the MME feeds back the terminal characteristics, and/or the service characteristics, and/or the demand characteristics to the base station according to the locally maintained mapping table based on a request of the base station.

Step S314, the HSS maintains the mapping relation table;

that is, the HSS performs editing operations such as an addition operation, a modification operation, and a deletion operation on the mapping relationship table, where the addition operation is an operation of adding a mapping relationship in at least one mapping relationship table, the modification operation is an operation of modifying a mapping relationship in at least one mapping relationship table, and the deletion operation is an operation of deleting a mapping relationship in at least one mapping relationship table.

Step S315, HSS synchronizes the operations of adding, modifying and deleting to MME.

And when the HSS synchronizes the adding, modifying and deleting operations to the MME, the MME locally maintains a mapping relation table according to the synchronized operations.

From the above, it can be seen that the base station, MME and HSS all maintain mapping tables locally. In other embodiments, if the MME finds that the terminal attribute corresponding to the APN requested by the base station is not in the locally maintained mapping relationship table, the MME may further send a synchronization request to the HSS to request synchronization of the latest operation (see step S316). In step S316, the MME may actively request the latest mapping relationship table from the HSS, and then the HSS synchronizes the latest editing operation to the MME based on the request of the MME.

In the technical solutions provided in step S314 and step S315, when the HSS performs an editing operation on the mapping relationship table, the HSS actively synchronizes with the MME.

As shown in fig. 3C, in a cell, there are 3 types of services: the method comprises the steps of electricity metering, parking geomagnetism and sharing single vehicles, wherein APNs of the electricity metering, the parking geomagnetism and the sharing single vehicles are APN _1, APN _2 and APN _3 respectively.

According to the table, the electric meter terminal is characterized by power supply, the service model is UL single-transmission, and the time delay can be tolerated to 60 s. For the electric meter, the power consumption and power control parameters are not optimized for prolonging the service life of the terminal; secondly, because the service model is UL single-transmission, when the base station senses that the terminal finishes the uplink service, the RRC connection can be released immediately, and the RRC connection burden of the base station side is relieved. Finally, since the delay can tolerate 60s, the parameters affecting the delay can be configured to be larger, and when the current base station resources are insufficient, the delay-insensitive service can be delayed and scheduled.

The parking geomagnetic terminal is not powered on, and the service model is Dual-transmission. For geomagnetism, in order to enable the battery life to reach 3-5 years, power consumption and power control related parameters need to be optimized; secondly, since the service model is Dual-transmission, when the base station senses the second service packet, the RRC connection can be released immediately, and the RRC connection burden on the base station side is relieved.

The shared bicycle terminal is not powered, and the service model is Multi-transmission. For a shared bicycle, in order to enable the service life of a battery to reach 1 year, power consumption and related parameters of power control need to be optimized; secondly, since the service model is Multi-transmission, the base station cannot sense the number of data packet interactions, and therefore, the duration of a ue inactivity timer should be reasonably set by comprehensively considering the influence of link conditions and network interaction delay.

As shown in fig. 3D, in a cell, there are many electric meter terminals, for example, N electric meter terminals, and their APNs are APN _1 to APN _ N, respectively, which may cause random access congestion if they initiate random access at the same time. Based on APNs (APN _1 to APN _ N) of the UE, the eNB can acquire the delay tolerance of the terminals, and because the delay tolerance of the electric meter terminals is higher, when random access congestion occurs, the eNB can set a larger time interval T for initiating the next random access, and all electric meter terminals randomly select the time interval for initiating the next random access between 0 and T, so that the terminals can be staggered in the random access time as far as possible, and the random access congestion probability is reduced.

An embodiment of the present invention provides a wireless control method, which is applicable to a base station side for configuring UE-specific parameters based on an APN type, and fig. 4 is a schematic flow chart illustrating an implementation of the wireless control method according to the embodiment of the present invention, and as shown in fig. 4, the method includes:

step S401, eNB acquires APN type of UE;

for example, eNB obtains the APN type of the UE from the MME through S1AP signaling.

Step S402, the base station configures UE-specific parameters of the UE based on the APN type;

the UE-specific parameters include, but are not limited to, parameters affecting power consumption, parameters affecting power control (p0-UE-NPUSCH-r13), parameters affecting connection reestablishment after link failure (rlf-TimersAndConstants), parameters affecting data transmission rate (twoHARQ-ProcessConfig), and parameters affecting power consumption and latency (C-DRX). The parameters affecting the power consumption include a UE-inactivity (UE-inactivity timer) timer duration, a data inactivity (datainactivity) timer, and a rai-Activation.

The base station configures the UE-specific parameter of the UE based on the APN, and the method comprises the following steps: the base station may also comprehensively configure the UE-specific parameters of the terminal based on the APN or information such as a combination APN, QoS, UE radio capability, and the like.

The base station configures the UE-specific parameters of the UE based on the APN, and the method comprises the following steps: the base station can also judge the terminal type, the service type and the requirement type of the UE based on the APN, and configure the UE-specific parameter based on the terminal type, the service type and the requirement type of the UE on the basis.

Example 1:

in the present embodiment, based on Release 14(Release 14, R14) protocol, the MME informs the eNB of the relevant APN Information through a UE Information Transfer message. Meanwhile, the method is suitable for UP and CP schemes, and backward compatibility is supported. Fig. 5A is a schematic flow chart illustrating an implementation process of transmitting an APN based on R14 according to an embodiment of the present invention, as shown in fig. 5A, the method includes:

step S501, the UE sends MSG3 to the eNB;

step S502, the eNB sends a retrieval user information (Retrieve UE information) message to the MME;

step S503, the MME sends a UE information Transfer (UE information Transfer) message to the eNB;

step S504, the eNB sends MSG4 to the UE;

from the above, in R14, regardless of the attachment, the caller data transmission after the attachment, or the called data reception, after receiving the MSG3 message sent by the UE, the eNB may send a Retrieve UE Information message to the MME to request to acquire the UE related Information, and the MME replies to the eNB with a UE Information Transfer message to inform the UE of the UE related Information. An APN field may be added to the UE information Transfer message to inform the eNB of APN information of the UE corresponding to the eNB.

For example, the operator network has 3 APNs, which are numbered APN _1, APN _2 and APN _3, and respectively correspond to a meter reading service, a bicycle service and a street lamp service. Now, in 1 cell corresponding to the base station, there is a served UE, and by acquiring APN information thereof, the base station can determine a service type associated with the UE. If the data is the meter reading service, the base station can configure a set of wireless parameters related to the meter reading service for the UE; if the single-vehicle service is available, the base station can configure a set of wireless parameters related to the single-vehicle service for the UE; if the traffic is street lamp traffic, the base station may configure a set of wireless parameters related to the street lamp traffic for the UE. In addition, the base station can acquire the downlink RSRP value of the UE and combine the downlink RSRP value with the service type of the UE, so as to determine whether the UE is a weak coverage terminal on the basis that different service types correspond to different weak coverage thresholds.

Example 2:

based on the R13 protocol, the MME informs the eNB of the related APN information through an Initial Context Setup Request message. The method is suitable for a User Plane (UP) scheme and supports backward compatibility. Fig. 5B is a schematic diagram of an implementation flow of transmitting an APN based on a user plane according to an embodiment of the present invention, and as shown in fig. 5B, the method includes:

in step S511, the MME sends an Initial Context Setup Request (Initial Context Setup Request) message (APN) to the eNB.

In the Release 13(Release 13, R13) UP scheme, the MME needs to transmit an Initial Context Setup Request to the eNB, regardless of the attach, the transmission of the caller data after the attach, or the reception of the called data, so an APN field for informing the eNB of the APN information of the corresponding UE may be added to the Initial Context Setup Request message.

For example, the operator network has 3 APNs, which are numbered APN _1, APN _2, and APN _3, and respectively correspond to a meter reading service, a bicycle service, a road service, and the like. Now, in 1 cell corresponding to the base station, there is a served UE, and by acquiring APN information thereof, the base station can determine a service type associated with the UE. If the data is the meter reading service, the base station can configure a set of wireless parameters related to the meter reading service for the UE; if the single-vehicle service is available, the base station can configure a set of wireless parameters related to the single-vehicle service for the UE; if the traffic is street lamp traffic, the base station may configure a set of wireless parameters related to the street lamp traffic for the UE. In addition, the base station can acquire the downlink RSRP value of the UE and combine the downlink RSRP value with the service type of the UE, so as to determine whether the UE is a weak coverage terminal on the basis that different service types correspond to different weak coverage thresholds.

Example 3:

based on the R13 protocol, the MME informs the eNB of the relevant APN information through a Downlink NAS Transport (Downlink NAS Transport) message. The method is suitable for a Control Plane (CP) scheme and supports backward compatibility. Fig. 5C is a schematic diagram illustrating an implementation process of transmitting an APN based on a control plane according to an embodiment of the present invention, and as shown in fig. 5C, the method includes:

step S521: the MME sends a Downlink DAS Transport (APN) message to the eNB.

As shown in fig. 5C, in the R13CP scheme, the MME needs to transmit Downlink NAS Transport to the eNB regardless of whether the MME is attached, or is used for transmitting the attached caller data or receiving the called data, so that an APN field may be added to the Downlink NAS Transport message to inform the eNB of APN information of the UE.

As can be seen from the above embodiments, the base station performs UE-specific parameter configuration based on the APN; for example, the base station judges the type of the UE terminal, the service type and the requirement type based on the APN, and performs UE-specific parameter configuration based on the APN. For another example, the base station configures UE-specific parameters based on APN, QoS, UE radio capability, and other comprehensive information; or judging the terminal type, the service type and the requirement type based on the information, and configuring the UE-specific parameter based on the judgment.

Compared with the prior art, the embodiment has the following technical advantages: a base station acquires an APN of a terminal (for example, the APN of the terminal is acquired through an S1AP message), and configures related UE-specific parameters based on the APN; or judging the terminal type, the service type and the demand type based on the APN, and performing wireless control on the basis of the APN, such as configuring UE-specific parameters. Compared with the current wireless control method which is not based on the terminal characteristics, or the service characteristics or the demand characteristics, the method optimizes the efficiency of the network and the terminal.

In the LTE system, the types of services of mobile phone users are various, but all services are internet services, and therefore, the mobile phone users are marked by using the unified APN representing the PDN of the internet. In an NB-IoT system, the types of terminals/service types of the internet of things (in the internet of things, terminals and service types are often in one-to-one correspondence) are very rich, for example, meter, street lamps, and bicycles, and different terminal/service types are in different demands, for example, the meter terminal and the bicycle terminal have very high requirements on power consumption, and street lamps are not sensitive to power consumption due to power supply; the single traffic is sensitive to time delay, but the street lamp traffic can tolerate a certain degree of time delay. Therefore, in the NB-IoT system, it is necessary to configure different APNs for different terminals, or service types, or terminals/services with the same type of requirements (such as power consumption, delay, rate, etc.), so that the network can perform some customized operations on a certain terminal/service type through the APN, thereby improving user experience.

The embodiment provides a method for configuring UE-specific parameters based on APN type on a base station side. And the base station configures the UE-specific parameter based on the APN. For example, the base station determines the UE terminal type, the service type, and the demand type based on the APN, and performs radio control based on the APN, for example, UE-specific parameter configuration. For another example, the base station comprehensively considers information based on other characteristics (QoS, UE radio capability) that can judge terminal characteristics, service characteristics, or demand characteristics, and configures UE-specific parameters; or judging the terminal type, the service type and the demand type based on the information, and performing wireless control on the basis of the information, such as configuring UE-specific parameters.
