Description

Resource processing method and device

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a resource processing method and device.

Background

Mobile communication has been deeply changing people's lives, but the pursuit of higher performance mobile communication has never been stopped. In order to cope with the explosive mobile data traffic growth, massive device connection, and various new business and application scenarios that are continuously emerging in the future, a fifth Generation (5th-Generation, 5G) mobile communication system has been produced. The internet of things is used as a component of 5G, and the market demand is rapidly increased.

Currently, the 3rd Generation Partnership Project (3 GPP) standard has proposed solutions for the features of the Internet of Things based on cellular networks, such as cellular-based narrowband Internet of Things (NB-IoT) networks and enhanced Machine Type Communication (eMTC) networks, which use the features of narrowband technology to carry IoT traffic. The NB-IoT network applies a new air interface technology independent of the existing cellular network Long Term Evolution (LTE), so that the terminal cost is lower, and the supported rate and mobility are lower. The eMTC network belongs to a part of a traditional cellular network, and can provide IoT service support for the characteristics of the Internet of things in an LTE network.

Compared with the traditional cellular network, the service and terminal equipment of the Internet of things have the following characteristics: low-rate and long-period service: the internet of things traffic produces smaller packets and is generally not very sensitive to latency. The requirement of mass connection is as follows: for terminal devices of the internet of things such as large-scale deployed intelligent water/electricity meters, intelligent homes, automobiles and wearable devices, a large number of terminal devices (more than tens of thousands) of the type may exist under one NB-IoT base station. The low cost requirement is as follows: compared with the existing cellular network terminal, the NB-IoT requires the terminal to have lower cost so as to realize the mass deployment of the terminal equipment, and the requirement of low cost requires the realization complexity of the terminal to be very low. Low power consumption requirements: the NB-IoT requires lower power consumption of the terminal, so that the battery power of the terminal is saved, the overlong standby time of the equipment is ensured, and the labor cost for replacing the battery is saved. The service arrival rate is low: usually, there is a service only for several hours or even more than one day, and a considerable part is uplink triggering, i.e. the network does not page the terminal, and only when the terminal has uplink service, the network will send downlink response data.

NB-IoT and eMTC are continuously optimized for small data transmission of the Internet of things in Rel-15 edition and Rel-16 edition so as to save time delay and power consumption of small data packet transmission. For example, a Pre-configured Uplink Resource (PUR) is designed, the base station configures Uplink transmission resources to the terminal in advance through RRC signaling, and the terminal can directly use the Pre-configured Uplink Resource in an IDLE state (IDLE) if there is Uplink data to be sent, so as to avoid a random access process, and facilitate saving of power consumption of the terminal. At present, the rational utilization of resources preconfigured for an idle terminal is a problem to be solved.

Disclosure of Invention

The embodiment of the application provides a resource processing method and device, which are used for reasonably utilizing network resources preconfigured for idle state UE.

A first aspect of the present application provides a resource processing method, applied to a network device, the method including:

indicating a first resource to a terminal device UE through a dedicated signaling, wherein the first resource is used for the communication between the UE and the network device in an idle state, and the first resource comprises a first uplink resource;

sending a first message to a core network device, where the first message includes the configuration of the first resource and an identifier of the UE, and the first message is used to store the configuration of the first resource of the UE;

if uplink data is received from the idle-state UE on the first uplink resource, sending a second message to core network equipment, wherein the second message comprises the uplink data and an identifier of the UE, and the second message is used for acquiring the configuration of the first resource of the UE;

In the scheme, after the network equipment pre-configures the first resource for the UE, the pre-configuration information is sent to the core network equipment, and the core network equipment stores the pre-configuration information. When the network device receives uplink data sent by idle-state UE on the first uplink resource, the network device can obtain the pre-configured resource of the UE through the core network device, thereby performing downlink scheduling of subsequent UE. It can be seen that, the network device in this scheme does not store the resource information configured for the idle UE, but stores the resource information by the core network device, and the core network device stores the correspondence between the first resource and the identifier of the UE, and acquires the corresponding first resource according to the identifier of the UE when uplink data sent by the UE is subsequently received. The resource pre-configuration process enables the network device to smoothly acquire pre-configuration information from the core network device after receiving the idle-state UE uplink transmission, and perform downlink scheduling.

In a possible implementation manner, the downlink signaling is used to indicate to release the first resource; the method further comprises the following steps: and sending an indication for deleting the configuration of the first resource to the core network equipment.

In the foregoing implementation manner, the network device may send the downlink signaling on the first downlink resource according to the preconfigured information obtained from the core network device, and instruct the idle-state UE to release the first resource, that is, notify the idle-state UE that the preconfigured information is invalid. Meanwhile, the network equipment sends corresponding instructions to the core network equipment, so that the core network equipment deletes the information of the first resource configured for the idle UE, and the phenomenon that the running speed of the core network equipment is influenced because invalid resource information occupies the memory space of the core network equipment is avoided.

in response to the first message, saving a configuration of the first resources of the UE;

receiving a second message from the network device, the second message including uplink data of the UE and an identity of the UE; wherein the UE is in an idle state;

sending a third message to the network device in response to the second message, the third message including the configuration of the first resource.

In the scheme, the core network device receives information of a first resource preconfigured for the idle-state UE by the network device, and associates the first resource with the identifier of the UE, so that the first resource corresponding to the UE is sent to the network device when uplink data sent by the UE is received, and the network device can smoothly acquire the preconfigured information for downlink scheduling.

in response to the fourth message, saving a configuration of the second resources of the UE.

In the above implementation manner, the core network device receives a new resource, that is, a second resource, configured for the idle UE by the network device, updates the resource configuration information of the UE, deletes the previous first resource, associates the second resource with the identifier of the UE, and sends the new second resource to the network device when uplink data sent by the UE is subsequently received, so that the network device performs downlink scheduling on the new second resource.

In one possible implementation, the method further includes: receiving, from the network device, an indication to delete the configuration of the first resource.

In the implementation manner, the network device actively releases the first resource preconfigured for the idle UE, notifies the UE that the first resource is invalid through the downlink signaling, and notifies the core network device to delete the configuration of the invalid first resource, so as to avoid that the invalid resource information occupies the memory space of the core network device and affects the operating speed of the core network device.

Detailed Description

Fig. 1 is a schematic view of an application scenario of the resource processing method provided in the present application. As shown in fig. 1, the resource processing method provided in the present application may be applied to any wireless communication System, for example, may be applied to an internet of things System such as an NB-IoT System and an eMTC System that require terminal equipment to have low complexity and low power consumption, and may also be applied to a conventional Long Term Evolution (LTE), an evolved Universal Mobile Telecommunications System (UMTS), and the like. Such as the IoT communication system shown in fig. 1, the solution is applicable to various terminal devices that can access a base station for information interaction, and may be a wireless terminal or a wired terminal, where the wireless terminal may be a device that provides voice and/or other service data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. Wireless terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (RAN), which may exchange language and/or data with the RAN. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). A wireless Terminal may also be called a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), a User Equipment (User Equipment), for example: computers, household appliances, automobiles, televisions and the like. And is not limited herein.

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

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

The uplink resource may be periodic, and the uplink resource may be configured through an RRC message, where the RRC message includes but is not limited to: RRC connection setup message/RRC Reestablishment message/RRC connection Resume message/RRC connection Release message/RRC connection Reconfiguration message/data early transfer complete message (RRCConnectionSetup/Reestablishment/Resume/Release/Reconfiguration/Release/EarlyDataComplete), and the like.

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

1. In an RRC idle state, if the UE has uplink data and pre-configures uplink resources, the UE may use the pre-configured uplink resources to transmit data, and the following conditions are required to be satisfied when sending the uplink data:

the uplink resource size meets the UE data volume;

UE has uplink synchronization;

the uplink resources are efficient.

2. And the UE transmits uplink data by using the pre-configured resources.

3. And after the UE finishes sending the uplink data, monitoring a Physical Downlink Control Channel (PDCCH).

The monitoring of the PDCCH is performed in a timer, and the monitoring purpose may include one or more of the following:

possible uplink retransmission scheduling;

acknowledgement of successful uplink transmission;

scheduling downlink response data;

and scheduling the downlink RRC message.

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

indicating the UE to return to an RRC idle state (possibly carrying downlink response data at the same time), indicating that data transmission is finished and no further downlink response data is to be sent; alternatively, the first and second electrodes may be,

the UE is indicated to enter the RRC connected state, and may not finish sending out in one data packet due to the fact that the downlink data or downlink response data cached by the core network is too large, and the UE needs to access the connected state for receiving.

The network device may also release, reconfigure, etc. the pre-configured resources of the UE through RRC messages.

Based on the resource using method, the preconfigured uplink resource is used by the UE in an idle state, the UE can send uplink data by using the uplink resource preconfigured by the network device at any time, and correspondingly, after receiving the uplink transmission of the UE, the network device may perform downlink transmission scheduling, for example, message 4. Therefore, the network device needs to obtain the configuration information of the UE at least after receiving the uplink transmission, however, in the Control Plane (CP) transmission scheme, data is directly transmitted between the core network and the terminal device in a Non-access stratum (NAS) signaling form at present, 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 terminal. Therefore, the network device cannot acquire the resource information preconfigured for the terminal device, and if the idle terminal device performs cell reselection due to position movement or signal change, the network device cannot sense that the terminal device has left the original cell or reselected to another cell, and at this time, the preconfigured resource information fails, and the network device cannot timely release the failed resource due to no sensing, which causes resource waste.

Therefore, it is necessary to design a corresponding resource processing method for NB-IoT and eMTC, so that the base station can smoothly perform downlink scheduling when receiving uplink data transmitted by idle UE, and simultaneously ensure efficient utilization of preconfigured network resources.

Based on the above technical problem, the present application provides a resource processing method, which introduces a reasonable pre-configured resource information storage and release mechanism, so that a network device can smoothly acquire configuration information of a UE after receiving uplink transmission, and perform subsequent downlink scheduling. Meanwhile, the network equipment can timely acquire the message after the UE changes the cell, and invalid pre-configured resources are released. The resource processing method of the present application is described in detail below by using specific embodiments, it should be noted that the following specific embodiments may be combined with each other, and the description of the same or similar contents is not repeated in different embodiments.

Fig. 3 is a first interaction diagram of the resource processing method provided in the present application. The scheme relates to a network device, UE and core network device in a network, as shown in fig. 3, the specific interactive process of the method is as follows:

step 101, the network device indicates the first resource to the UE through dedicated signaling.

The first resource is used for the UE to communicate with the network equipment in an idle state. Specifically, the first resource includes a first uplink resource and a first downlink resource. The idle UE 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 preconfigured first resource may be periodic. The RRC signaling messages include, but are not limited to, RRC connection setup messages, RRC reestablishment messages, RRC connection recovery messages, RRC connection release messages, RRC connection reconfiguration messages.

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

It should be noted that, the above pre-configuration process of the UE in the idle state is implemented by dedicated RRC signaling, and when the UE is in the RRC idle state, the UE may directly transmit uplink data according to the first uplink resource pre-configured for the UE by the network device without performing an RRC connection process.

Wherein the preconfigured first resources include at least one of: the period, starting point, validity period, size of transmission block, repetition times, modulation coding mode, bandwidth, frequency modulation information and the like of uplink resources for transmitting uplink data; the control channel configuration for scheduling uplink retransmission or downlink response messages (physical layer response signaling or RRC response message) after uplink transmission is finished includes a period, a starting point, a repetition number, and the like of a 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 indicating a first resource to a UE, a network device sends a first message to a core network device, where the first message is preconfigured information, which includes a configuration of the first resource and an identifier of the UE, and the first message is used to store the configuration of the first resource of the UE, that is, the core network device associates and stores the configuration of the first resource and the identifier of the UE according to the first message, so that the network device acquires the first resource preconfigured for the UE from the core network device and performs downlink scheduling, resource release, or reconfiguration, and the like.

Optionally, the first message may further include cell information when the network device pre-configures the resource for the UE, for example, an identifier of the cell or an identifier of the network device. I.e. the first message may also include an identity of the first cell or an identity of the network device in which the UE was located when the first resource was preconfigured.

It should be noted that the 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 the message, and the stored message may be in the form of a container. Of course, the first message may also be opaque to the core network device, that is, the core network device may read the pre-configuration information and perform corresponding processing actions, which is specifically described below and not specifically described herein.

Alternatively, the network device may send the first message through an S1 interface, and an S1 interface is used to transfer Session Management (SM) and Mobility Management (MM) information, i.e., signaling plane or control plane information.

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

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

And step 103, the idle-state UE sends uplink data on the first uplink resource.

In this embodiment, if there is uplink data to be sent by the idle UE, the idle UE may directly send the uplink data according to the first uplink resource preconfigured for the idle UE by the network device, but the following conditions need to be satisfied:

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

That is to say, the data amount of the idle UE sending the uplink data should be less than or equal to the data amount preconfigured for the UE by the network device, the UE has uplink synchronization, and the preconfigured first uplink resource is valid, and the idle UE can send the uplink data on the first uplink resource directly without RRC connection when the above conditions are met.

Optionally, the UE may carry the identifier of the UE when sending the uplink data. Optionally, in this embodiment of the present application, scrambling or masking may be performed on uplink data by using the identifier of the UE to implement 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 idle UE on the first uplink resource, the network device may send a second message to the core network device, where the second message may include the uplink data and an identifier of the UE. The second message is used for acquiring the configuration of the first resource of the UE. Optionally, the second message may further include an identifier of a second cell in which the UE is currently located, that is, an identifier of a cell in which the UE is located when the UE transmits uplink data.

The identifier of the second cell and the identifier of the first cell may indicate the same cell or may indicate different cells. If the identifier of the second cell and the identifier of the first cell indicate different cells, it indicates that the UE has cell reselection, at this time, the first resource preconfigured for the UE by the network device is invalid, and the UE in the second cell cannot send uplink data based on the first uplink resource.

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 receiving the second message sent by the network device, the core network device obtains, according to the identifier of the UE in the second message, the configuration of the first resource corresponding to the identifier of the UE, and sends, as a third message, the configuration of the first resource to the network device, 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 further include an identifier of the first cell and an identifier of the second cell.

Optionally, the third message in the present application may 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.

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

In this step, the network device receives a 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 a second resource, where the second resource is used for the UE to communicate with the network device in an idle state. After the network device sends the downlink instruction to the UE, a fourth message may also be sent 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 store the configuration of the second resource of the UE, that is, the core network device associates and stores the configuration of the second resource with the identifier of the UE according to the fourth message, so as to update the UE pre-configuration information.

In another possible implementation manner, the downlink instruction is used to instruct to release the first resource. After the network device sends 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. And the core network equipment deletes the pre-configuration information of the UE according to the indication.

Optionally, the network device may perform downlink scheduling on the UE by sending an RRC response message, and in the RRC response message, the network device may change or release the first resource preconfigured to the UE. After changing or releasing the first resource pre-configured for the UE, the network device sends an indication for changing or deleting the information of the first resource pre-configured for the UE to the core network device. Or the network equipment sends an indication for changing or deleting the information of the first resource preconfigured for the UE to the core network equipment while changing or releasing the first resource preconfigured for the UE.

It should be noted that, the preconfigured first resource in the present application is used for the idle UE to periodically send data, the UE may be an internet of things terminal, such as a water meter or a vehicle-mounted terminal, the internet of things terminal generally sends a reading for several hours, and a usage period of the resource may be an hour-level granularity. Therefore, after configuring the first resource for the UE, the network device does not store the preconfigured resource information, but sends the preconfigured resource information to the core network device.

The resource processing method provided by this embodiment provides a mechanism for storing and releasing preconfigured resource information, so that a network device can obtain resource information preconfigured for an idle UE after receiving uplink data transmitted by the UE, perform subsequent downlink scheduling, and autonomously change or release the preconfigured resource information in the downlink scheduling, thereby improving the flexibility of resource provisioning of the idle UE by the network device, avoiding network resource waste, and improving the utilization rate of network resources.

Fig. 4 is a second interaction diagram of the resource processing method provided in the present application. The scheme relates to a network device, UE and core network device in a network, as shown in fig. 4, the specific interactive process of the method is as follows:

step 201, the network device indicates the first resource to the UE through dedicated signaling.

In this embodiment, a first resource preconfigured for the UE by the network device is used for the UE to communicate with the network device through a first cell in an idle state, where 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 identity of the UE.

In this embodiment, after indicating the first resource to the UE, the network device sends a first message to the core network device, where the first message is pre-configuration information and includes a configuration of the first resource and an identifier of the UE. The first message is used to store the configuration of the first resource of the UE, that is, the core network device associates and stores the configuration of the first resource with the identity of the UE according to the first message. It should be noted that the first message of this embodiment is opaque to the core network device, that is, the core network device may read the pre-configuration information and determine whether the UE performs cell reselection, specifically refer to step 205.

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

Step 203, the idle UE sends uplink data or signaling to the network device.

In this embodiment, in a possible case, the idle UE sends uplink data to the network device on the first uplink resource. In another possible case, the idle UE sends uplink signaling to the network device through a random access procedure. In another possible scenario, the idle UE sends uplink data or signaling to the network device through an Early Data Transmission (EDT) procedure. The network device receives uplink data from the UE in the first cell. In the second and third cases, 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 UE identity and the second cell identity.

In this embodiment, after receiving the uplink data or the signaling sent by the UE, the network device may acquire cell information, such as an identifier of the second cell, of the uplink data or the signaling sent by the UE. However, since the network device does not store the pre-configuration information of the UE, it cannot know whether the UE performs cell reselection. Therefore, the network device sends a second message including the identifier of the UE and the identifier of the second cell to the core network device, so that the core network device determines whether the UE performs cell reselection.

If the UE sends uplink data to the network device on the first uplink resource, optionally, the second message may further include the uplink data.

It should be noted that the second cell in this application may be understood as a cell where the UE is located when the UE sends uplink data or signaling, and the first cell in this application may be understood as a cell where the UE is located when the network device pre-configures the first resource for the UE. In this embodiment, the identifier of the second cell and the identifier 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 a second message sent by a network device, a core network device obtains, according to an identifier of a UE in the second message, a configuration of a first resource corresponding to the identifier of the UE and an identifier of a first cell, and when it is determined that the identifier of the second cell and the identifier of the first cell in the second message indicate different cells, the core network device sends a first indication to the network device, where the first indication includes information indicating the first resource and the identifier of the UE, and the network device releases the first resource according to the first indication.

Optionally, when determining that the identifier of the second cell in the second message and the identifier of the first cell indicate the same cell, the core network device sends a third message to the network device, where 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 for the network device to send downlink signaling or downlink data to the UE in an idle state. The downlink scheduling of the UE is the same as step 106 in the above embodiment, which may be referred to in the above embodiment specifically, and is not described herein again.

Step 206, the network device sends a downlink signaling to the UE, where the downlink signaling is used to indicate that the first resource is invalid.

In this embodiment, after releasing the first resource according to the first indication, the network device sends a downlink signaling to the UE, so that the UE knows that the first resource preconfigured for the UE by the network device is invalid.

Based on the foregoing embodiment, optionally, after releasing the first resource, the network device may further pre-configure a second resource for the UE, where the second resource is used for the UE to communicate with the network device through the second cell in an idle state. Wherein the second resource includes a second uplink resource and a second downlink resource. The network device indicates the second resource to the UE through the dedicated signaling, and the UE may send uplink data to the network device on the second uplink resource after the cell reselection occurs.

Optionally, after the network device pre-configures the second resource for the UE, a fourth message may be sent to the core network device, where the fourth message includes the configuration of the second resource and the identifier of the UE, so that the core network device stores the latest pre-configuration information of the UE.

The resource processing method provided by this embodiment provides a release mechanism of preconfigured resource information, and an application scenario is that UE switches between different cells of the same network device, and determines whether the UE performs cell reselection through judgment of core network device, and when it is determined that the UE performs cell reselection, the core network device notifies the network device to release a preconfigured first resource, thereby avoiding network resource waste and improving the utilization rate of network resources. In addition, after releasing the first resource of the first cell, the network device may also configure a second resource of a new cell for the UE, and start a mechanism for storing and releasing the second resource, so as to improve the flexibility of resource pre-configuration of the network device to the idle UE.

Fig. 5 is a third interaction diagram of the resource processing method provided in the present application. The scheme relates to a network device, UE and core network device in a network, as shown in fig. 5, the specific interactive process of the method is as follows:

step 301, the network device indicates the first resource to the UE through dedicated signaling.

Step 302, 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 identity of the UE.

In this embodiment, after indicating the first resource to the UE, the network device sends a first message to the core network device, where the first message is pre-configuration information and includes a configuration of the first resource and an identifier of the UE. The first message is used to store the configuration of the first resource of the UE, that is, the core network device associates and stores the configuration of the first resource with the identity of the UE according to the first message. It should be noted that the first message of 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 the pre-configuration information.

Step 303, the idle UE sends uplink data or signaling to the network device.

Steps 301 to 303 of this embodiment are the same as steps 201 to 203 of the embodiment in fig. 4, and reference may be made to the above embodiments for details, which are not described herein again.

Step 304, the network device sends a third message to the core network device, where the third message includes the UE identity.

In this embodiment, after receiving the uplink data or the signaling sent by the UE, the network device may acquire cell information, such as an identifier of the second cell, of the uplink data or the signaling sent by the UE. However, since the network device does not store the pre-configuration information of the UE, it cannot know the identity of the first cell where the UE is located during pre-configuration, and therefore, the network device sends a third message including the identity of the UE to the core network device to obtain the pre-configuration information of the UE.

If the UE sends uplink data to the network device on the first uplink resource, optionally, the third message may further include the uplink data.

If the UE sends uplink data or signaling to the network device through the second cell, optionally, the third message may further include an identifier of the second cell.

It should be noted that step 303 and step 304 in this embodiment may be regarded as: the core network equipment receives uplink data or signaling of the UE.

Step 305, the core network device sends a second message to the network device, where the second message includes the configuration of the first resource and the identity of the UE.

In this embodiment, after receiving the third message sent by the network device, the core network device obtains, according to the identifier of the UE in the third message, the configuration of the first resource corresponding to the identifier of the UE, and sends the configuration of the first resource and the identifier of the UE as the second message to the network device, so that the network device determines whether the UE performs cell reselection. Compared with the embodiment of fig. 4, the core network device in this embodiment does not read and process the pre-configuration information of the UE.

Optionally, the second message may further include an identifier of the first cell, or the configuration of the first resource in the second message includes the identifier of the first cell.

If the third message received from the network device includes the identifier of the second cell, optionally, the second message may further include the identifier of the second cell.

Step 306, the network device determines whether the UE performs cell reselection according to the second message, and if it is determined that the UE performs cell reselection, the network device releases the first resource.

And the network equipment acquires the identifier of the first cell in which the UE is positioned when the first resource is preconfigured from the second message, and releases the first resource when the identifier of the second cell and the identifier of the first cell indicate different cells.

Step 307, the network device sends an indication to delete the configuration of the first resource to the core network device.

Step 308, the network device sends a downlink signaling to the UE, where the downlink signaling is used to indicate that the first resource is invalid.

The resource processing method provided by this embodiment provides a release mechanism of preconfigured resource information, and an application scenario is that a UE switches between different cells of the same network device, the network device obtains resource information preconfigured for the UE through a core network device, and the network device determines whether the UE performs cell reselection, and when it is determined that the UE performs cell reselection, the network device releases a preconfigured first resource and notifies the core network device to delete the preconfigured resource information of the UE, thereby avoiding network resource waste, improving the utilization rate of network resources, avoiding invalid resource information occupying a memory space of the core network device, and improving the operating speed of the core network device.

Fig. 6 is a fourth interaction diagram of the resource processing method provided in the present application. The scheme relates to two network devices in a network, namely a first network device and a second network device, UE and core network device, wherein the first network device is the network device after cell reselection of the UE, and the second network device is the original network device (namely the network device with the pre-configured first resource). As shown in fig. 7, the specific interactive process of the method is as follows:

step 401, the second network device indicates the first resource to the UE through dedicated signaling.

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

Step 402, the second network device sends a second message to the core network device, where the second message includes the configuration of the first resource and the identity of the UE.

In this embodiment, after indicating the first resource to the UE, the second network device sends a second message to the core network device, where the second message is the provisioning information and includes the configuration of the first resource and the identifier of the UE. And the core network equipment associates and stores the configuration of the first resource and the identity of the UE according to the second message. It should be noted that the second message of 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 the pre-configuration information.

Step 403, the idle UE sends uplink data or signaling to the first network device.

In this embodiment, the UE performs cell reselection, and sends an uplink signaling to the first network device through a random access process, or sends uplink data or signaling to the first network device through a data early-transmission process. At this time, the core network device, the first network device, and the second network device do not yet perceive that the UE has performed cell reselection, and need to learn through the following steps.

Step 404, the first network device sends a third message to the core network device, where the third message includes the UE identity.

In this embodiment, if the UE initiates the random access procedure through the first network device, the third message may include an identifier of the UE; if the UE initiates the data early-transfer process through the first network device, the third message may include the identifier of the UE and the uplink data.

Optionally, the third message may further include an identifier of the second cell, and the second cell may be any cell covered by the first network device.

It should be noted that step 404 in this embodiment may be regarded as that the first network device sends 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 identifier of the UE according to the identifier of the UE in the third message, and the core network device sends the configuration of the first resource and the identifier of the UE as the first message to the first network device, so that the first network device determines whether the UE performs cell reselection.

Optionally, the first message may further include an identifier of the first cell, or the configuration of the first resource in the first message includes the identifier of the first cell. The first cell is any cell under the coverage of the second network equipment.

If the third message received from the first network device includes the identifier of the second cell, optionally, the first message may further include the identifier of the second cell.

Step 406, the first network device determines whether the UE performs cell reselection according to the first message.

The first network equipment acquires the identification of the first cell where the UE is located when the first resource is preconfigured from the first message, and determines whether the UE performs cell reselection according to the identification of the first cell and the identification of the second cell.

Step 407, if it is determined that the UE performs cell reselection, the first network device sends a first indication to the core network device, where the first indication is used to indicate the core network device to notify the second network device to release the first resource.

When the identifier of the first cell and the identifier of the second cell indicate different cells, the first network device determines that the UE performs cell reselection, and sends a first indication to the core network device, and after receiving the first indication, the core network device performs step 408 and step 409.

Step 408, the core network device deletes the configuration of the first resource.

Step 409, the core network device sends an indication of releasing the configuration of the first resource to the second network device.

It should be noted that, the

steps

408 and 409 in this embodiment are not limited to the above execution sequence, and the step 409 may be executed first and then the step 408 is executed, or the step 408 and the step 409 may be executed simultaneously.

On the basis of the foregoing embodiment, optionally, after step 409, the method may further include: and the core network equipment receives the confirmation message which is returned by the second network equipment and used for releasing the first resource. The acknowledgement message is used to indicate that the second network device has released the first resource.

Optionally, the first network device may pre-configure a second resource for the UE, where the second resource is used for the UE to communicate with the first network device through the second cell in an idle state. Wherein the second resource includes a second uplink resource and a second downlink resource. The first network device indicates the second resource to the UE through dedicated signaling. The UE may send uplink data to the first network device on the second uplink resource after the cell reselection occurs.

Optionally, after the first network device pre-configures the second resource for the UE, the first network device may further send the configuration of the second resource and the identifier of the UE to the core network device, so that the core network device stores the latest pre-configuration information of the UE.

The resource processing method provided in this embodiment provides a mechanism for releasing preconfigured resource information, and an application scenario is that a UE is switched from a first cell of an original network device (a second network device) to a second cell of a new network device (the first network device), based on the scenario, the new network device obtains resource information, which is configured for the UE in advance by the original network device, from a core network device, and when determining that the UE performs cell reselection, the new network device notifies the core network device that the UE performs cell reselection, and after receiving an instruction of the new network device, the core network device deletes resource information, which is preconfigured for the UE by the original network device, and instructs the original network device to release the preconfigured resource of the UE. The method enables the original network equipment to timely know that the UE has cell reselection, releases invalid network resources as soon as possible, avoids network resource waste, improves the utilization rate of the network resources, simultaneously avoids invalid resource information from occupying the memory space of the core network equipment, and improves the running speed of the core network equipment.

Fig. 7 is a fifth interaction diagram of the resource processing method provided in the present application. The scheme relates to two network devices in a network, namely a first network device (a network device after cell reselection of UE) and a second network device (an original network device), the UE and a core network device, and the specific interactive process of the method is as follows:

step 501, the second network device indicates the first resource to the UE through dedicated signaling.

Step 502, the second 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 indicating the first resource to the UE, the second network device sends a first message to the core network device, where the first message is the provisioning information and includes the configuration of the first resource and the identifier of the UE. The first message is used to store the configuration of the first resource of the UE, that is, the core network device associates and stores the configuration of the first resource with the identifier of the UE according to the first message. It should be noted that the first message of this embodiment is opaque to the core network device, that is, the core network device may read the provisioning information and determine whether the UE performs cell reselection, see step 505 specifically.

Optionally, the first message further includes an identifier of the first cell, or the configuration of the first resource in the first message includes the identifier of the first cell. The first cell is any cell covered by the second network equipment.

Step 503, the idle UE sends uplink data or signaling to the first network device.

Step 504, the first network device sends a second message to the core network device, where the second message includes the UE identity and the second cell identity.

In this embodiment, if the UE initiates the random access procedure through the first network device, the second message includes the identifier of the UE and the identifier of the second cell; if the UE initiates the data early-transfer process through the first network device, the second message may include the identifier of the UE, the identifier of the second cell, and the uplink data. The second cell may be any cell under the coverage of the first network device.

It should be noted that step 504 in this embodiment may be regarded as that the core network device receives uplink data or signaling of the UE from the first network device.

And step 505, the core network device determines whether the UE performs cell reselection according to the second message.

The difference from the embodiment of fig. 6 is that: the core network device determines whether the UE has a cell reselection, instead of the first network device indication. Specifically, after receiving a second message sent by the first network device, the core network device obtains, according to the identity of the UE in the second message, the configuration of the first resource corresponding to the identity of the UE, where the configuration of the first resource includes the identity of the first cell. And the core network equipment determines whether the UE has cell reselection according to the identifier of the second cell in the second message and the acquired identifier of the first cell. When the identity of the first cell and the identity of the second cell indicate different cells, it is determined that the UE has cell reselection, and steps 506 and 507 are performed.

Step 506, the core network device sends a first indication to the second network device, where the first indication is used to indicate to release the first resource.

The core network equipment sends a first instruction to the second network equipment, and the second network equipment releases the first resource according to the first instruction.

Step 507, the core network device deletes the configuration of the first resource.

Based on the foregoing embodiment, optionally, the first network device may pre-configure the UE with a second resource, where the second resource is used for the UE to communicate with the first network device through the second cell in the idle state. Wherein the second resource includes a second uplink resource and a second downlink resource. The first network device indicates the second resource to the UE through dedicated signaling. The UE may send uplink data to the first network device on the second uplink resource after the cell reselection occurs.

It should be noted that, the

steps

506 and 507 in this embodiment are not limited to the above execution sequence, and the step 507 may be executed first and then the step 506 is executed, or the step 506 and the step 507 may be executed simultaneously.

The resource processing method provided in this embodiment provides a mechanism for releasing preconfigured resource information, where an application scenario is that a UE is switched from a first cell of an original network device (a second network device) to a second cell of a new network device (the first network device), based on the scenario, a core network device obtains cell information of the UE from the new network device, and when it is determined that the UE performs cell reselection, deletes resource information preconfigured for the UE by the original network device, and instructs the original network device to release preconfigured resources of the UE. The method enables the original network equipment to timely know that the UE has cell reselection, releases invalid network resources as soon as possible, avoids network resource waste, improves the utilization rate of the network resources, simultaneously avoids invalid resource information from occupying the memory space of the core network equipment, and improves the running speed of the core network equipment.
