Description

Resource processing method and device

Technical field

The embodiments of the present application relate to the field of communication technologies, and in particular, to a resource processing method and device.

Background technique

Mobile communication has profoundly changed people's lives, but people's pursuit of higher performance mobile communication has never stopped. In order to cope with the explosive growth of mobile data traffic, massive device connections, and various new services and application scenarios that are constantly emerging in the future, the fifth-generation (5th-Generation, 5G) mobile communication system has emerged. As a component of 5G, the Internet of Things has seen rapid market demand growth.

At present, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) standard has been based on cellular networks, and has proposed solutions for the characteristics of the Internet of Things, such as the cellular-based Narrow Band Internet of Things (NB-IoT) network And enhanced Machine Type Communication (eMTC) network, using the characteristics of narrowband technology to carry IoT services. Among them, the NB-IoT network uses a new air interface technology that is independent of the long-term evolution (LTE) of the existing cellular network, with lower terminal costs, lower supported speeds and lower mobility. The eMTC network is a part of the traditional cellular network and can provide IoT service support in the LTE network according to the characteristics of the Internet of Things.

Compared with traditional cellular networks, Internet of Things services and terminal equipment have the following characteristics: low service rate and long cycle: Internet of Things services generate smaller data packets and are generally not very sensitive to delay. Massive connection requirements: For large-scale deployment of smart water/electric meters, smart homes, automobiles, wearable devices and other IoT terminal devices, there may be a large number of such terminal devices (more than tens of thousands) under an NB-IoT base station. Low-cost requirements: Compared with existing cellular network terminals, NB-IoT requires lower terminal costs in order to achieve mass deployment of terminal equipment, and low-cost requirements require that the complexity of terminal implementation is very low. Low power consumption requirements: NB-IoT requires lower power consumption of the terminal, thereby saving terminal battery power, ensuring the long standby time of the device, and saving the labor cost of replacing the battery. Service arrival rate is low: usually there is only one service in a few hours or even more than a day, and a considerable part of it is triggered by the uplink, that is, the network will not page the terminal, and the network will only send the downlink response data when the terminal has the uplink service.

NB-IoT and eMTC continue to optimize the small data transmission of the Internet of Things in the Rel-15 version and Rel-16 version to save the delay and power consumption of small data packet transmission. For example, to design a pre-configured uplink resource (PUR), the base station configures the uplink transmission resource to the terminal through RRC signaling in advance, and the terminal is in the idle state (IDLE), if there is uplink data to send, it can be used directly The pre-configured uplink resources avoid the random access process and help save terminal power consumption. At present, reasonable utilization of resources pre-configured for idle state terminals is a problem to be solved.

detailed description

Figure 1 is a schematic diagram of an application scenario of the resource processing method provided by this application. As shown in Figure 1, the resource processing method provided by this application can be used in any wireless communication system, for example, it can be applied to IoT systems such as NB-IoT systems and eMTC systems that require low complexity and low power consumption of terminal devices, and can also be applied In the traditional Long Term Evolution (LTE), the evolved Universal Mobile Telecommunications System (UMTS), etc. For example, the IoT communication system shown in Figure 1. This solution can be applied to various terminal devices that can access the base station for information interaction. It can be a wireless terminal or a wired terminal. The wireless terminal can provide voice and/or other A device with business data connectivity, a handheld device with wireless connection function, or other processing device connected to a wireless modem. A wireless terminal can communicate with one or more core networks via a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal For example, they can be portable, pocket-sized, handheld, computer-built or vehicle-mounted mobile devices, which exchange language and/or data with the wireless access network. For example, personal communication service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, and personal digital assistants (Personal Digital Assistant, PDA) and other equipment. Wireless terminals can also be called systems, subscriber units (Subscriber Unit), subscriber stations (Subscriber Station), mobile stations (Mobile Station), mobile stations (Mobile), remote stations (Remote Station), remote terminals (Remote Terminal), Access terminal (Access Terminal), user terminal (User Terminal), user agent (User Agent), user equipment (User Device or User Equipment), such as computers, home appliances, automobiles, televisions, etc. It is not limited here.

Based on the above application scenario, FIG. 2 is a schematic flow diagram of a resource usage method. In the NB-IoT system, as shown in Figure 2, the process of resource usage is as follows:

0. The network equipment pre-configures uplink resources for the UE through user-specific RRC signaling.

Among them, the uplink resource can be periodic, and the uplink resource can be configured through RRC messages. RRC messages include but are not limited to: RRC connection establishment message/RRC reestablishment message/RRC connection recovery message/RRC connection release message/RRC connection reconfiguration message/ Early data transmission complete message (RRCConnectionSetup/Reestablishment/Resume/Release/Reconfiguration/EarlyDataComplete), etc.

Wherein, the configured resource information includes at least one of the following: period, starting point, validity period, transmission block size, modulation and coding mode, bandwidth, frequency modulation information, and so on.

1. In the RRC idle state, if the UE has uplink data and pre-configured uplink resources, it can use the pre-configured uplink resources to transmit data. Sending uplink data must meet the following conditions:

The uplink resource size meets the UE data volume;

The UE has uplink synchronization;

Uplink resources are effective.

2. The UE uses pre-configured resources to send uplink data.

3. After the UE finishes sending the uplink data, it monitors the physical downlink control channel PDCCH.

Among them, PDCCH monitoring is performed within a timer running, and the monitoring purpose may include one or more of the following types:

Possible uplink retransmission scheduling;

Response to successful uplink transmission;

Downlink response data scheduling;

Scheduling of downlink RRC messages.

4. After receiving the uplink data sent by the UE, the network equipment may send a downlink RRC message to the UE for the following purposes:

Instruct the UE to return to the RRC idle state (and possibly carry downlink response data at the same time), indicating that the data transmission is complete and there is no further downlink response data to be sent; or,

Instructing the UE to enter the RRC connected state, it may be because the downlink data or downlink response data buffered by the core network is too large to be sent in one data packet, and the terminal needs to access the connected state to receive.

The network equipment can also release and reconfigure the UE's pre-configured resources through RRC messages.

Based on the above resource usage method, the pre-configured uplink resources are used by the UE in the idle state. The UE can use the uplink resources pre-configured by the network equipment to send uplink data at any time. Correspondingly, after the network equipment receives the UE’s uplink transmission, it may Perform downlink transmission scheduling, such as message 4. Therefore, the network equipment needs to obtain the configuration information of the UE at least after receiving the uplink transmission. However, in the current control plane (CP) transmission scheme, the data is based on the non-access stratum (NAS) information. The order form is directly transmitted between the core network and the terminal device, and the network device only plays a role of transparent transmission, that is, the network device does not store any pre-configuration information for the idle state terminal. Therefore, the network device cannot learn the resource information pre-configured for the terminal device. If the idle state terminal device performs cell reselection due to location movement or signal change, the network device cannot perceive that the terminal device has left the original cell or reselected to another cell. In the cell, the pre-configured resource information at this time has become invalid, and the network equipment cannot release the invalid resources in time due to unawareness, resulting in a waste of resources.

Therefore, it is necessary to design corresponding resource processing methods for NB-IoT and eMTC, so that the base station can smoothly perform downlink scheduling when receiving uplink data transmitted by idle UEs, and at the same time ensure efficient use of pre-configured network resources.

Based on the above technical problems, this application proposes a resource processing method that introduces a reasonable pre-configured resource information storage and release mechanism, so that network equipment can smoothly obtain UE configuration information after receiving uplink transmission, and perform subsequent downlink scheduling. At the same time, the network device can learn the message in time after the UE changes the cell, and release invalid pre-configured resources. The following specific embodiments are used to describe the resource processing method of the present application in detail. It should be noted that the following specific embodiments can be combined with each other, and the same or similar content will not be repeated in different embodiments.

Step 101: The network device indicates the first resource to the UE through dedicated signaling.

Among them, the first resource is used for the UE to communicate with the network device in the idle state. Specifically, the first resource includes a first uplink resource and a first downlink resource. The UE in the idle state may send uplink data or signaling on the first uplink resource, and receive downlink data or signaling sent by the network device on the first downlink resource.

In this embodiment, the network device may indicate the first resource to the UE through RRC signaling, that is, pre-configure the first resource for the UE through RRC signaling. Wherein, the pre-configured first resource may be periodic. RRC signaling messages include but are not limited to RRC connection establishment messages, RRC reestablishment messages, RRC connection recovery messages, RRC connection release messages, and RRC connection reconfiguration messages.

In the embodiments of the present application, for the configuration of the same pre-configured resource (for example, the first resource), the data structure of the configuration on each message or each network node may not be completely the same; for the identity of the same UE, each The composition of the identity of the UE on the message or on each node may not be completely the same.

It should be noted that the above-mentioned pre-configuration process for the UE in the idle state is implemented through dedicated RRC signaling. When the UE is in the RRC idle state, the uplink data can be transmitted directly according to the first uplink resource pre-configured by the network device. , No RRC connection process is required.

Wherein, the pre-configured first resource includes at least one of the following: period, starting point, validity period, transmission block size, repetition number, modulation and coding method, bandwidth, frequency modulation information, etc. of the uplink resource used to transmit uplink data; After the end of the uplink transmission, the control channel configuration for scheduling uplink retransmission or downlink response messages (physical layer response signaling or RRC response messages) includes the period, starting point, and number of repetitions of the search space.

Step 102: The network device sends a first message to the core network device, where the first message includes the configuration of the first resource and the identifier of the UE.

In this embodiment, after the network device indicates the first resource to the UE, it sends a first message to the core network device. The first message is pre-configuration information, including the configuration of the first resource and the identifier of the UE. The first message is used for The configuration of the first resource of the UE is saved, that is, the core network device associates the configuration of the first resource with the identity of the UE according to the first message and stores it, so that the network device can obtain the first pre-configured configuration for the UE from the core network device. Resources, perform downlink scheduling, resource release or reconfiguration, etc.

Optionally, the foregoing first message may also include cell information when the network device pre-configures resources for the UE, such as the identity of the cell or the identity of the network device. That is, the first message may also include the identity of the first cell or the network device where the UE is located when the first resource is pre-configured.

It should be noted that the above-mentioned first message may be transparent to the core network device, that is, the core network device does not read or process the message, but only stores it. At this time, the stored message may be in the form of a container. Of course, the above-mentioned first message may also be opaque to the core network device, that is, the core network device can read the pre-configuration information and perform corresponding processing actions. For details, refer to the following text, which is not specifically expanded here.

Optionally, the network device may send the above-mentioned first message through an S1 interface, which is used to transmit session management (SM) and mobility management (MM) information, that is, signaling plane or control plane information.

Optionally, the core network device may be a mobility management entity (Mobility Management Entity, MME for short).

It should be noted that when the network equipment is connected to the EPC (4G core network), the network equipment is connected to the MME through the S1 interface. When the network equipment is connected to the 5GC (5G core network), the network equipment is connected through the NG interface and AMF (access Connected to the mobility management function network element).

Step 103: The UE in the idle state sends uplink data on the first uplink resource.

In this embodiment, if a UE in an idle state has uplink data to send, it can directly send uplink data according to the first uplink resource pre-configured by the network device, but the following conditions need to be met:

The size of the first uplink resource meets the UE data volume, the UE has uplink synchronization, and the first uplink resource is valid.

That is to say, the amount of uplink data sent by the UE in the idle state should be less than or equal to the amount of data pre-configured by the network device, the UE has uplink synchronization, and the pre-configured first uplink resource is valid. When the above conditions are met , The UE in the idle state may directly send the uplink data on the first uplink resource without going through the RRC connection.

Optionally, the UE may carry the identity of the UE when sending uplink data. Optionally, in the embodiment of the present application, the identifier of the UE may be used to scramble or mask the uplink data to realize that the uplink data carries the identifier of the UE.

Step 104: The network device sends a second message to the core network device, where the second message includes uplink data and the identifier of the UE.

After receiving the uplink data sent by the UE in the idle state on the first uplink resource, the network device may send a second message to the core network device, and the second message may include the uplink data and the identifier of the UE. The second message is used to obtain the configuration of the first resource of the UE. Optionally, the second message may also include the identity of the second cell where the UE is currently located, that is, the identity of the cell where the UE is located when the uplink data is sent.

Wherein, the identity of the second cell and the identity of the first cell may indicate the same cell, or may indicate different cells. If the identity of the second cell and the identity of the first cell indicate different cells, it means that the UE has cell reselection. At this time, the first resource pre-configured by the network device for the UE is invalid, and the UE in the second cell cannot be based on the first uplink resource. Send upstream data.

Step 105: The core network device sends a third message to the network device, where the third message includes the configuration of the first resource.

In this embodiment, after the core network device receives the second message sent by the network device, the core network device obtains the configuration of the first resource corresponding to the UE identifier according to the UE identifier in the second message, and sets the The configuration is sent to the network device as a third message, so that the network device performs downlink scheduling of the UE according to the third message.

Optionally, the third message sent by the core network device to the network device may also include the identity of the first cell and the identity of the second cell.

Optionally, the third message in this application can be sent in the following two messages: a downlink non-access stratum transmission message DL NAS TRANSPORT or a connection establishment indication message CONNECTION ESTABLISHMENT INDICATION.

Step 106: The network device sends downlink data or signaling to the UE.

In this step, the network device receives the third message sent by the core network device, and sends downlink data or signaling to the UE in the idle state through the first downlink resource in the third message.

In a possible implementation manner, the downlink instruction is used to indicate the second resource, and the second resource is used for the UE to communicate with the network device in the idle state. After sending the downlink instruction to the UE, the network device may also send a fourth message to the core network device, where the fourth message includes the configuration of the second resource and the identifier of the UE. The fourth message is used to save the configuration of the second resource of the UE, that is, the core network device associates the configuration of the second resource with the identity of the UE according to the fourth message and stores it, so as to update the UE's preconfiguration information.

In another possible implementation manner, the downlink instruction is used to instruct to release the first resource. After sending the downlink instruction to the UE, the network device may also send an instruction to delete the configuration of the first resource to the core network device. The core network device deletes the pre-configuration information of the UE according to the instruction.

Optionally, the network device may perform downlink scheduling on the UE by sending an RRC response message. In the RRC response message, the network device may change or release the first resource pre-configured for the UE. After modifying or releasing the first resource pre-configured for the UE, the network device sends an instruction to the core network device to modify or delete the information about the first resource pre-configured for the UE. Or, the network device, while changing or releasing the first resource pre-configured for the UE, sends an instruction to the core network device to change or delete the information about the first resource pre-configured for the UE.

It should be noted that the first resource pre-configured in this application is used by the idle UE to periodically send data. The UE may be an IoT terminal, such as a water meter or a vehicle-mounted terminal. The IoT terminal is usually several hours Sending a reading, the resource usage cycle may be hourly granularity. Therefore, the network device does not store the pre-configured resource information after configuring the first resource for the UE, but sends the pre-configured resource information to the core network device.

The resource processing method provided in this embodiment provides a mechanism for saving and releasing pre-configured resource information, so that network equipment can obtain the resource information pre-configured for the UE after receiving the uplink data transmitted by the idle UE, and perform subsequent downlink scheduling. In the downlink scheduling, the pre-configured resource information can be changed or released independently, which improves the flexibility of the network equipment to pre-configure the resources of idle UEs, avoids waste of network resources, and improves the utilization of network resources.

FIG. 4 is a schematic diagram of the second interaction of the resource processing method provided by this application. The solution involves a network device, UE, and core network device in the network. As shown in Figure 4, the specific interaction process of the method is:

Step 201: The network device indicates the first resource to the UE through dedicated signaling.

In this embodiment, the first resource pre-configured by the network device for the UE is used for the UE to communicate with the network device through the first cell when the UE is in an idle state, and the first resource includes a first uplink resource and a first downlink resource.

Step 202: The network device sends a first message to the core network device, where the first message includes the configuration of the first resource and the identifier of the UE.

In this embodiment, after the network device indicates the first resource to the UE, it sends a first message to the core network device. The first message is pre-configuration information, including the configuration of the first resource and the UE's identity. The first message is used to save the configuration of the first resource of the UE, that is, the core network device associates the configuration of the first resource with the identity of the UE according to the first message and stores it. It should be noted that the first message in this embodiment is opaque to the core network device, that is, the core network device can read the pre-configuration information and determine whether the UE has cell reselection. For details, refer to step 205.

Optionally, the first message further includes the identity of the first cell, or the configuration of the first resource includes the identity of the first cell.

Step 203: The UE in the idle state sends uplink data or signaling to the network device.

In this embodiment, a possible situation is that the UE in the idle state sends uplink data to the network device on the first uplink resource. In another possible situation, the UE in the idle state sends uplink signaling to the network device through a random access process. In another possible situation, a UE in an idle state sends uplink data or signaling to a network device through an early data transmission (EDT) process. In the first case described above, the network device receives uplink data from the UE in the first cell. In the second and third cases described above, the network device receives uplink data or signaling from the UE in the second cell.

Step 204: The network device sends a second message to the core network device, where the second message includes the identity of the UE and the identity of the second cell.

In this embodiment, after receiving the uplink data or signaling sent by the UE, the network equipment can learn the information of the cell where the UE sends the uplink data or signaling, such as the identity of the second cell. However, since the network device does not store the pre-configuration information of the UE, it cannot know whether the UE has cell reselection. Therefore, the network device sends the second message including the identity of the UE and the identity of the second cell to the core network device, so that the core network device determines whether the UE has cell reselection.

If the UE sends uplink data to the network device on the first uplink resource, optionally, the above-mentioned second message may also include uplink data.

It should be noted that the second cell in this application can be understood as the cell where the UE is when the UE sends uplink data or signaling, and the first cell in this application can be understood as the UE where the UE is when the network device pre-configures the first resource for the UE. Of the cell. In this embodiment, the identity of the second cell and the identity of the first cell may indicate the same cell, or may indicate different cells.

Step 205: The core network device sends a first instruction to the network device, where the first instruction is used to instruct to release the first resource.

In this embodiment, after receiving the second message sent by the network device, the core network device obtains the configuration of the first resource corresponding to the UE's identity and the identity of the first cell according to the UE identity in the second message. When the identity of the second cell and the identity of the first cell in the second message indicate different cells, the core network device sends a first indication to the network device. The first indication includes the information indicating the first resource and the UE identity, and the network device The first instruction releases the first resource.

Optionally, when determining that the identity of the second cell in the second message and the identity of the first cell indicate the same cell, the core network device sends a third message to the network device. The third message includes the configuration of the first resource, so that The network device performs downlink scheduling of the UE according to the third message. The first resource includes a first uplink resource and a first downlink resource, and the first downlink resource is used by the network device to send downlink signaling or downlink data to a UE in an idle state. The downlink scheduling of the UE is the same as step 106 of the foregoing embodiment. For details, refer to the foregoing embodiment, and details are not described herein again.

Step 206: The network device sends downlink signaling to the UE, where the downlink signaling is used to indicate the failure of the first resource.

In this embodiment, after the network device releases the first resource according to the first instruction, it sends downlink signaling to the UE, so that the UE learns that the first resource pre-configured by the network device has failed.

On the basis of the above-mentioned embodiment, optionally, after releasing the first resource, the network device may also pre-configure a second resource for the UE. The second resource is used for the UE to communicate with the network device through the second cell when the UE is in an idle state. . The second resource includes a second uplink resource and a second downlink resource. The network device indicates the second resource to the UE through dedicated signaling, and the UE may send uplink data to the network device on the second uplink resource after cell reselection occurs.

Optionally, after the network device pre-configures the second resource for the UE, it may also send a fourth message to the core network device. The fourth message includes the configuration of the second resource and the identity of the UE, so that the core network device stores the latest information of the UE. Pre-configuration information.

The resource processing method provided in this embodiment provides a mechanism for releasing pre-configured resource information. The application scenario is that the UE switches between different cells of the same network device, and the core network device determines whether the UE has cell reselection. When it is determined that UE cell reselection occurs, the core network device notifies the network device to release the pre-configured first resource, avoiding waste of network resources and improving the utilization of network resources. In addition, after the network device releases the first resource of the first cell, it can also configure the second resource of the new cell for the UE, and start the storage and release mechanism for the second resource, so as to improve the network device's resource pre-processing for idle UEs. Configuration flexibility.

This solution involves two network devices in the network, namely the first network device and the second network device, the UE and the core network device. The first network device is the network device after the UE undergoes cell reselection, and the second network device is The original network device (that is, the network device pre-configured with the first resource). As shown in Figure 7, the specific interaction process of this method is:

The second message is pre-configuration information, including the configuration of the first resource and the UE's identity. The core network device associates the configuration of the first resource with the identifier of the UE according to the second message and stores it. It should be noted that the second message in this embodiment is transparent to the core network device, that is, the core network device does not read or process the pre-configuration information, but only stores it.

Step 403: The UE in the idle state sends uplink data or signaling to the first network device.

In this embodiment, the UE undergoes cell reselection, and the UE in the idle state sends uplink signaling to the first network device through the random access process, or the UE in the idle state sends uplink data to the first network device through the early data transmission process.

It should be noted that step 404 in this embodiment may be regarded as the first network device sending uplink data or signaling of the UE to the core network device.

Step 405: The core network device sends a first message to the first network device, where the first message includes the configuration of the first resource and the identifier of the UE.

In this embodiment, after receiving the third message sent by the first network device, the core network device obtains the configuration of the first resource corresponding to the UE identifier according to the UE identifier in the third message, and the core network device sets the first The configuration of the resource and the identifier of the UE are sent to the first network device as a first message, so that the first network device determines whether the UE has cell reselection.

The resource processing method provided in this embodiment provides a mechanism for releasing pre-configured resource information. The application scenario is that the UE switches from the first cell of the original network device (the second network device) to the new network device (the first network device).
