Background
In the field of internet of things, time delay is one of key indexes of service quality. Due to fragmentation and diversification of internet of things services, there are practically very different delay requirements, such as: the reporting service of meter reading such as water and electricity is insensitive to the time delay requirement; for services such as shared bicycle needing remote control, service experience is greatly influenced by time delay; even for some internet of things terminals, the delay requirement is different with different data, for example, for some monitoring services, the conventional data reporting is not sensitive to delay, and when emergency data such as alarm is generated, the delay requirement is very high.
In order to reduce the delay, the service requirement is usually satisfied by expanding the carrier frequency of the base station.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
In order to solve the problem of the prior art, embodiments of the present invention provide an access resource configuration method, an apparatus, a base station, and a medium. First, the access resource allocation method provided in the embodiment of the present invention is explained in detail below.
Fig. 1 is a flowchart illustrating an access resource configuration method applied to a base station according to an embodiment of the present invention. The access resource configuration method applied to the base station can comprise the following steps:
s101: and receiving at least one user service requirement message sent by the service platform.
S102: and selecting one access resource configuration scheme from at least one pre-configured access resource configuration scheme aiming at the user identification information included in each user service requirement information.
The access resource configuration scheme is a scheme for reducing access delay of the terminal equipment corresponding to the user identification information.
S103: and configuring the access resources for the terminal equipment according to the selected access resource configuration scheme.
S104: and sending the access resource to the terminal equipment so that the terminal equipment accesses the base station based on the access resource.
The service platform of the internet of things, which is intensively built by an operator, collects user information, wherein the user information comprises service information, correlation information, delay requirement information, rate requirement information and the like.
The service information includes a service name, a service region, service time, and the like. Wherein a user may only purchase services for a particular region and for a particular time period with respect to quality of service guarantees. For example, a sharing vehicle manufacturer purchases a service related to the quality of service guarantee of a subway exit during the next work period.
The associated information refers to user identity information, user payment subscription information, user grade information and the like.
The time delay requirement information and the speed requirement information are used for realizing the time delay requirement under the specific speed requirement according to the relation between the time delay and the speed index in the data transmission stage.
The service platform generates user service demand information for each user. The user service requirement information includes user identification information, priority, delay requirement, rate requirement, Tracking Area (TA), effective time, priority service restriction requirement and lifetime.
Wherein, the user identification information: the information may be International Mobile Subscriber Identity (IMSI) information, or may be a random number generated by the service platform for the Subscriber.
The priority is used to indicate the priority of the user. The higher the priority of the user is, the more priority the base station has to ensure its service quality.
The delay requirement is the maximum delay index requirement of the user, i.e. the requirement of ensuring the service quality, and the user delay cannot exceed the index requirement.
Rate requirements: under the condition of meeting the time delay requirement, the minimum rate index requirement of the user is the requirement of ensuring the service index, and the user rate cannot be lower than the index requirement.
For the effective TA and the effective time, if the user only purchases the service of the related service quality assurance for a specific region (for example, a certain alarming terminal of the internet of things only works in a certain cell) and/or a specific time period (for example, 5 pm to 7 pm every day), the "effective TA" and/or the "effective time" correspondingly fills the region and time information, if there is no requirement, any one or both of the two items of information may be empty, and particularly, if the service base station of the user can be made clear, for example, for some terminals of the internet of things with fixed positions not moving, the effective TA may also directly fill the base station identification information.
For the priority traffic limitation requirement, each user may be provided with a limitation requirement of priority service for quality of service assurance by the network, such as a time limit, or a traffic limit, beyond which the network no longer guarantees quality of service. If empty, this is not a limitation.
And if the life cycle in the user service demand information, namely the effective time of the configuration information, exceeds the effective time, the user service demand information is invalid.
The service platform encapsulates user service requirement information in Non-access stratum (NAS) signaling, and transparently transmits the information to a base station where a target user is located through a Mobility Management Entity (MME), where the NAS signaling is carried in Radio Resource Control (RRC) signaling and is transmitted to a terminal device of a corresponding user through a wireless network of the base station.
And the service platform transmits the user service requirement information to all target base stations indicated by the effective TA information. The target base station is selected according to the following modes: the TA configured by the target base station is already included in the valid TA information, or the valid TA field directly configures the base station identification information of the target base station. If the valid TA information is empty, the valid TA information needs to be transmitted to all base stations in the whole network.
The communication between the service platform and the base station may be transparent transmission through an S1 interface of an MME or a Serving GateWay (S-PW) or a Public Data Network GateWay (P-GW), or control information transmission through Operation Administration and Maintenance (OAM).
The base station selects an access resource configuration scheme from at least one pre-configured access resource configuration scheme aiming at user identification information included in each user service requirement information; configuring access resources for the terminal equipment according to the selected access resource configuration scheme; and sending the access resource to the terminal equipment so that the terminal equipment accesses the base station based on the access resource.
The access resource configuration scheme may include:
the first scheme is as follows: and configuring different schemes corresponding to the access resources for different terminal equipment.
Such as: allocating access resources A and B to the terminal device corresponding to the user 1, allocating access resource C to the terminal device corresponding to the user 2, allocating access resource D to the terminal device corresponding to the user 3, and the like. The access resources configured for different terminal devices are different.
Scheme II: and the number of the access sequences configured for the terminal equipment with the first priority is more than that of the access sequences configured for the terminal equipment with the second priority.
Such as: and configuring 10 access sequences for the terminal equipment with the first priority, and configuring 5 access sequences for the terminal equipment with the second priority. It is understood that the priorities of a plurality of terminal devices may be the same, and in this case, the terminal devices with the same priority may share the same access resource.
Such as: the first terminal device, the second terminal device and the third terminal device all have the first priority, and the first terminal device, the second terminal device and the third terminal device share 10 access sequences.
At this time, an access conflict may occur, so an access flow supporting the flush resolution is adopted when the terminal device accesses.
The third scheme is as follows: and the access back-off time configured for the terminal equipment with the first priority is smaller than the access back-off time configured for the terminal equipment with the second priority.
Such as: the access backoff time configured for the terminal equipment of the first priority is T, and the access backoff time configured for the terminal equipment of the second priority is 2T.
At this time, a plurality of terminal devices with different priorities may share the same access resource. At this time, an access conflict may occur, so an access flow supporting the flush resolution is adopted when the terminal device accesses.
Wherein the first priority is higher than the second priority.
When the first scheme is adopted to configure the access resource for the terminal equipment and the terminal equipment has service requirements, the access flow of the terminal equipment is as follows: the terminal device sends a Physical Random Access Channel (PRACH), and the base station replies a Random Access Response (RAR). The terminal equipment is successfully accessed and then sends an RRC connection request.
The embodiment of the invention can reduce the access time delay of the terminal equipment by configuring different access resources for different terminal equipment.
When the second scheme is adopted to configure the access resources for the terminal equipment and the terminal equipment has service requirements, the access flow of the terminal equipment is as follows: and the terminal equipment sends PRACH and the base station replies RAR. The terminal equipment initiates an access conflict resolution request, the access conflict resolution request comprises user identification information corresponding to the terminal equipment, the base station receives the conflict resolution request, resolves access conflicts for the terminal equipment according to the user identification information, and then sends conflict resolution information to the terminal equipment. The terminal equipment is successfully accessed and then sends an RRC connection request.
In a possible implementation manner of the embodiment of the present invention, when the base station resolves an access conflict for the terminal device according to the user identification information, if the base station allows the terminal device to access, the base station sends a conflict resolution message to the terminal device, and if the base station does not allow the terminal device to access, the base station does not send the conflict resolution message to the terminal device.
The embodiment of the invention ensures that a plurality of terminal devices with the same priority can share the same access resource by configuring the access sequence number for the terminal device with the first priority more than the access sequence number configured for the terminal device with the second priority, adopts the configuration of the shared access resource, and can help the base station to confirm the user identification information by sending the user identification information through the terminal device, thereby preventing certain low-priority terminal devices from using high-priority access resources unconformily, and helping the base station to verify whether the terminal device is legal or not by reporting the user identification information. While enabling the base station to accommodate more terminal devices.
When the third scheme is adopted to configure the access resource for the terminal equipment and the terminal equipment has service requirements, the access flow of the terminal equipment is as follows: and the terminal equipment sends PRACH and the base station replies RAR. The terminal equipment initiates an access conflict resolution request, the access conflict resolution request comprises user identification information corresponding to the terminal equipment, the base station receives the conflict resolution request, resolves access conflicts for the terminal equipment according to the user identification information, and then sends conflict resolution information to the terminal equipment. The terminal equipment is successfully accessed and then sends an RRC connection request.
According to the embodiment of the invention, the access back-off time configured for the terminal equipment with the first priority is shorter than the access back-off time configured for the terminal equipment with the second priority, so that a plurality of terminal equipments with different priorities can share the same access resource, and the base station can be helped to confirm the user identification information by adopting the shared access resource configuration and sending the user identification information through the terminal equipment. While enabling the base station to accommodate more terminal devices.
The embodiment of the present invention does not limit the manner of resolving access conflicts, and any available manner can be applied to the embodiment of the present invention.
In a possible implementation manner of the embodiment of the present invention, after receiving the user service requirement information sent by the service platform, the base station may broadcast a first message including a load condition of the base station.
Specifically, a load field is added in the existing broadcast message, and the load field is filled according to the user service requirement information, so that the load condition of the base station is represented, the terminal equipment can conveniently and evenly select a proper base station, the capacity of each carrier is maximally utilized, and the time delay introduced by unnecessary load balancing is reduced.
In a possible implementation manner of the embodiment of the present invention, the load field may be determined according to the number of users to be served by the base station and the service requirement, where the quality of service needs to be guaranteed. Generally, the larger the number of users, the larger the traffic demand, and the heavier the load. The design of a payload field is as follows: in order to accelerate the cell search time of the terminal equipment, the load field uses 2 bits of Information reserved in a main system Information Block (MIB), the base station only judges according to the number of users, and sets 3 user number thresholds X1, X2 and X3, and when the number of users is less than X1, the load field is 00; when the number of users is between X1 and X2, the load field is 01; when the number of users is between X2 and X3, the load field is 10; when the number of users is greater than X3, the load field is 11.
In a possible implementation manner of the embodiment of the present invention, broadcast Information configuring an access resource in a System Information Block (SIB) may be further updated as follows: for different access classes, different access resources are configured in the broadcast, including the transmission time, the transmission sequence and the backoff time when the access fails. Different from the broadcast signaling of the access resource configuration which is not prioritized by the conventional base station, the new SIB includes multiple pieces of access resource configuration information, such as { access class 1, access resource configuration 1}, { access class 2, access resource configuration 2}, and the like.
In a possible implementation manner of the embodiment of the present invention, if the effective time included in the user service requirement information is not empty, the base station starts to periodically broadcast the first message including the load condition of the base station from a first time point before the effective time until the effective time is reached; the difference value between the effective time and the first time point is a first preset time length.
Assuming that the first preset time period is 5 seconds, the base station starts to periodically broadcast the first message including the load condition of the base station 5 seconds ahead of the effective time until the effective time is reached.
At this time, the terminal device can read the base station broadcast 3 seconds ahead of the effective time.
In a possible implementation manner of the embodiment of the present invention, if the effective time included in the user service demand information is empty, the base station starts to periodically broadcast the first message including the load condition of the base station from a second time point before the end time point corresponding to the lifetime included in the user service demand information until the end time point is reached; and the difference value between the ending time point and the second time point is a second preset time length.
And if the second preset time is 5 seconds, the base station starts to periodically broadcast the first message including the load condition of the base station 5 seconds ahead of the end time point corresponding to the life cycle until the user service demand information is expired.
At this time, the terminal device may read the base station broadcast 3 seconds ahead of the end time point corresponding to the lifetime.
After the terminal device obtains the base station load information from the MIB, the base station with the lowest load can be selected to reside. If a plurality of base stations are loaded, the terminal equipment selects the base station with the best wireless channel to reside at the moment. And after the terminal equipment resides in the base station, reading the access resource configuration information in the SIB.
In one possible implementation manner of the embodiment of the present invention, the base station may be an Internet of Things (IoT) base station.
And when the terminal equipment is successfully accessed to the base station, the base station communicates with the terminal in a data transmission stage.
When the scheme one is adopted, since the PRACH resources of the terminal device and the user service requirement information are in one-to-one correspondence, after the terminal device accesses the base station through the scheme one, the base station can demodulate the access information, and further can query information such as priority, delay requirement information, rate requirement information, and the like of the terminal device. And the base station allocates resources in the data transmission stage to the terminal equipment according to the inquired priority, the inquired time delay requirement information and the inquired speed requirement information so as to ensure the service of the terminal equipment and reduce the time delay of the terminal equipment in the data transmission stage.
When the second scheme or the third scheme is adopted, because the user identification information and the user service demand information are in one-to-one correspondence, after the terminal device accesses the base station through the second scheme or the third scheme, the base station can acquire the user identification information from the access conflict resolution request sent by the terminal device, and further can inquire information such as the priority, the delay requirement information and the rate requirement information of the terminal device. And the base station allocates resources in the data transmission stage to the terminal equipment according to the inquired priority, the inquired time delay requirement information and the inquired speed requirement information so as to ensure the service of the terminal equipment and reduce the time delay of the terminal equipment in the data transmission stage.
In a possible implementation manner of the embodiment of the present invention, the terminal device with higher priority may be preferentially scheduled in the data transmission phase.
In a possible implementation manner of the embodiment of the present invention, if the base station or the terminal finds that the lifetime in the user service requirement information is overtime, and if the service platform does not issue and configure new user service requirement information, the base station or the terminal considers that the user service requirement information is invalid, and the network does not provide service guarantee any more. Therefore, to continuously ensure the service quality, the service platform needs to regenerate new user service requirement information before expiration, and reinitiate and complete the process in the present solution.
By the access resource allocation method provided by the embodiment of the invention, differentiated network services are provided for different users, and the utility of each carrier can be exerted to the maximum as much as possible, namely, the service requirements of the users are met under the condition of not expanding carrier frequencies, so that the investment cost of operators is reduced, and the popularization of the service of the Internet of things is facilitated. Through the access resource allocation method provided by the embodiment of the invention, the operator has the capability of providing differentiated services for different users, so that the added value of the Internet of things of the operator is increased, for example, the operator can set different service quality grades for different paid users to provide different services, and the user experience of the operator is ensured. The user can flexibly customize various operator services according to the self service requirement, thereby reducing the expense of the user, for example, the user can be started only in a specific time period or a specific area; or for certain specific terminals, only for emergency data. The operator can also make different service strategies, provide differentiated value-added services for the users and meet the service requirements of different users.
