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 drastically changed people's lives, but the pursuit of higher performance mobile communication has never stopped. In order to cope with the future explosive mobile data traffic growth, mass device connection, and various new services and application scenarios that are continuously emerging, a fifth Generation (5G) mobile communication system has been developed. The Internet of things is used as a component of 5G, and the market demand of the Internet of things is rapidly increased.

Currently, the third generation partnership project (3rd Generation Partnership Proiect,3GPP) standard has been based on cellular networks, solutions have been proposed for characteristics of the internet of things, such as cellular-based narrowband internet of things (Narrow Band Internet of Things, NB-IoT) networks and enhanced machine-like communication (enhanced Machine Type Communication, eMTC) networks, utilizing characteristics of narrowband technology to carry IoT traffic. Wherein the NB-IoT network applies a new air interface technology independent of existing cellular network long term evolution (Long Term Evolution, LTE), the terminal cost is lower, and the supported rate and mobility are lower. The eMTC network is part of a traditional cellular network, and may provide IoT service support in an LTE network for internet of things features.

Compared with the traditional cellular network, the service and terminal equipment of the Internet of things have the following characteristics: traffic low rate, long period: the data packets generated by the internet of things service are smaller and are generally not very sensitive to time delay. Mass connection requirements: for large-scale deployment of intelligent water/electricity meters, intelligent homes, automobiles, wearable devices and other internet of things terminal devices, a large number of terminal devices (over tens of thousands) of this type may exist under one NB-IoT base station. Low cost requirements: compared with the existing cellular network terminal, the NB-IoT requires lower cost of the terminal to realize mass deployment of terminal equipment, and the requirement of low cost requires low complexity of realization of the terminal. Low power consumption requirements: NB-IoT requires lower power consumption of the terminal, thereby conserving terminal battery power, guaranteeing ultra-long standby time of the device, and thus saving labor costs for battery replacement. The service arrival rate is low: typically, there is only one service for several hours or even more than one day, and a significant portion is uplink triggered, i.e., the network will not page the terminal, and only if the terminal has uplink service, the network will send downlink response data.

NB-IoT and eMTC are continuously optimized for small data transmissions of the Internet of things in the Rel-15 version and the Rel-16 version to save time delay and power consumption of small data packet transmissions. For example, pre-configured uplink resources (Pre-configured Uplink Resource, PUR) are designed, the base station configures uplink transmission resources to the terminal in advance through RRC signaling, and if uplink data transmission exists in the IDLE state (IDLE), the terminal can directly use the Pre-configured uplink resources, so that a random access process is avoided, and power consumption of the terminal is saved. At present, reasonable utilization of resources preconfigured for idle state terminals 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, where the method includes:

indicating a first resource to a terminal device (UE) through a dedicated signaling, wherein the first resource is used for the UE to communicate with 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, wherein the first message comprises the configuration of the first resource and the identification of the UE, and the first message is used for storing the configuration of the first resource of the UE;

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

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

In the above implementation manner, the network device may send, according to the preconfiguration information obtained from the core network device, a downlink signaling on the first downlink resource, to instruct the idle UE to release the first resource, that is, notify the idle UE that the preconfiguration information has failed. Meanwhile, the network equipment sends a corresponding instruction to the core network equipment, so that the core network equipment deletes the information of the first resource configured for the idle-state UE, and the situation that the invalid resource information occupies the memory space of the core network equipment and influences the running speed of the core network equipment is avoided.

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

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

In the implementation manner, the core network device receives a new resource configured by the network device for the idle state UE, namely, a second resource, the core 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 when uplink data sent by the UE is subsequently received, the core network device sends the new second resource to the network device, so that the network device performs downlink scheduling on the new second resource.

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

In the implementation manner, the network device actively releases the first resource preconfigured for the idle-state UE, informs the UE that the first resource fails through the downlink signaling, and simultaneously informs the core network device to delete the configuration of the failed first resource, so that the situation that the invalid resource information occupies the memory space of the core network device and influences the operation speed of the core network device is avoided.

Detailed Description

Fig. 1 is an application scenario schematic diagram of a resource processing method provided in the present application. As shown in fig. 1, the resource processing method provided in the present application may be used in any wireless communication system, for example, may be applied to NB-IoT systems, eMTC systems, etc. internet of things systems that require low complexity and low power consumption of terminal devices, and may also be applied to conventional long term evolution (Long Term Evolution, LTE), evolved universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS), etc. Such as the IoT communication system shown in fig. 1, the scheme may be applied to various types of terminal devices that can access a base station for information interaction, either wireless terminals, which may be devices that provide voice and/or other traffic data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminals may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), which may be mobile terminals such as mobile phones (or "cellular" phones) and computers with mobile terminals, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access network. Such as personal communication services (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiation Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal Digital Assistant, PDAs), and the like. A wireless Terminal may also be called a system, subscriber Unit (Subscriber Unit), subscriber Station (Subscriber Station), mobile Station (Mobile Station), mobile Station (Mobile), remote Station (Remote Station), remote Terminal (Remote Terminal), access Terminal (Access Terminal), user Terminal (User Terminal), user agent (UserAgent), user equipment (UserDevice orUserEquipment), such as: computers, home appliances, automobiles, televisions, etc. And are not limited thereto.

Based on the above application scenario, fig. 2 is a flow chart of a resource usage method. In an 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 the special RRC signaling of the user.

Wherein, 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 complete message (RRCConnectionSetup/reinestiblastmessage/Release/Reconfiguration/EarlyDataComplete), etc.

Wherein the configured resource information includes at least one of: period, starting point, validity period, transport block size, modulation coding scheme, bandwidth, frequency modulation information, etc.

1. In the 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 for transmitting the uplink data:

the uplink resource size satisfies the UE data volume;

the UE has uplink synchronization;

the uplink resources are effective.

2. And the UE transmits uplink data by using the preconfigured resources.

3. After the UE transmits the uplink data, the UE monitors a physical downlink control channel PDCCH.

Wherein, the monitoring of the PDCCH is performed in a timer running, and the monitoring purpose may comprise one or more of the following:

possible uplink retransmission scheduling;

a response of successful uplink transmission;

scheduling downlink response data;

scheduling of downlink RRC messages.

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

indicating the UE to return to the RRC idle state (possibly carrying downlink response data at the same time), indicating that the data transmission is completed, and no further downlink response data is sent; or,

the UE is instructed to enter the RRC connected state, and the downlink data or the downlink response data buffered by the core network may be too large to be sent out in one data packet, so that 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 above resource usage method, the preconfigured uplink resource is used by the UE in an idle state, the UE may send uplink data using the uplink resource preconfigured by the network device at any time, and the network device may perform downlink transmission scheduling after receiving the uplink transmission of the UE, such as message 4. Therefore, the network device needs to acquire the configuration information of the UE at least after receiving the uplink transmission, however, in the Control Plane (CP) transmission scheme at present, data is directly transmitted between the core network and the terminal device in the form of Non-access stratum (NAS) signaling, and the network device only plays a role of transparent transmission, that is, the network device does not store any preconfiguration information for the idle state terminal. Therefore, the network device cannot acquire the resource information preconfigured for the terminal device, if the idle terminal device performs cell reselection due to position movement or signal change and the like, the network device cannot perceive that the terminal device has left the original cell or reselects other cells, at this time, the preconfigured resource information has failed, and the network device cannot timely release the failed resource due to no perception, so that resource waste is caused.

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 ensure efficient use of preconfigured network resources.

Based on the technical problems, the application provides a resource processing method, and a reasonable pre-configured resource information storage and release mechanism is introduced, so that network equipment can successfully acquire the configuration information of UE after receiving uplink transmission, and subsequent downlink scheduling is performed. Meanwhile, the network equipment can acquire the message in time after the UE changes the cell, and invalid pre-configured resources are released. The resource processing method of the present application will be described in detail with reference to specific embodiments, and it should be noted that several specific embodiments may be combined with each other, and for the same or similar content, the description will not be repeated in different embodiments.

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

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

Wherein the first resource is used for the UE to communicate with the network device in an idle state. Specifically, the first resources include 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, i.e. preconfigure 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 message, RRC reestablishment message, RRC connection recovery message, RRC connection release message, RRC connection reconfiguration message.

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 identical on each message or each network node; for the identity of the same UE, the composition of the identity of the UE may not be exactly the same on each message or each node.

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

Wherein the preconfigured first resource comprises at least one of: the period, the starting point, the effective period, the size of a transmission block, the repetition number, the modulation coding mode, the bandwidth, the frequency modulation information and the like of uplink resources used for transmitting uplink data; control channel configuration for scheduling uplink retransmission or downlink response message (physical layer response signaling or RRC response message) after the end of uplink transmission includes a period of search space, a start point, a number of repetitions, and the like.

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

In this embodiment, after the network device indicates the first resource to the UE, a first message, that is, pre-configuration information, is sent to the core network device, where the first message includes configuration of the first resource and an identifier of the UE, and the first message is used to save 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 obtains the first resource pre-configured for the UE from the core network device, and performs downlink scheduling, resource release, reconfiguration, and so on.

Optionally, the first message may further include cell information when the network device pre-configures resources for the UE, for example, an identity of a cell or an identity of the network device. I.e. the first message may also comprise an identity of the first cell or an identity of the network device where the UE is located when the first resource is 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 stores the message, where the stored message may be in a container form. Of course, the first message may also be opaque to the core network device, i.e. the core network device may read the preconfigured information and perform corresponding processing actions, see in particular the following, which is not specifically expanded herein.

Alternatively, the network device may send the first message through an S1 interface, where the 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 (Mobility Management Entity, MME for short).

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

Step 103, the idle UE sends uplink data on the first uplink resource.

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

The first uplink resource size satisfies the UE data volume, the UE has uplink synchronization, and the first uplink resource is effective.

That is, the data amount of uplink data sent by the UE in the idle state should be less than or equal to the data amount preconfigured by the network device, the UE has uplink synchronization, the preconfigured first uplink resource is valid, and in the case that the above condition is met, the UE in the idle state may send uplink data directly on the first uplink resource without RRC connection.

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

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

After the network device receives the uplink data sent by the idle UE on the first uplink resource, a second message may be sent to the core network device, where the second message may include the uplink data and the identifier of the UE. The second message is used to obtain a 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 uplink data is transmitted.

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 identification of the second cell and the identification of the first cell indicate different cells, it is indicated that the cell reselection exists in the UE, and at this time, the first resource preconfigured for the UE by the network device fails, 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 the configuration of the first resource corresponding to the identifier of the UE according to the identifier of the UE in the second message, and sends the configuration of the first resource as a third message 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: the downlink non-access stratum transmits a 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 one possible implementation, 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 when 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 for storing 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 preconfiguration information of the UE.

In another possible implementation, the downlink instruction is used to instruct to release the first resource. After the network device sends the downlink instruction to the UE, an indication of deleting the configuration of the first resource may also be sent to the core network device. And the core network equipment deletes the preconfiguration 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, where the network device may change or release the first resource preconfigured for the UE. After changing or releasing the first resources preconfigured for the UE, the network device sends an indication to the core network device to change or delete the information of the first resources preconfigured for the UE. Or, the network device sends an indication of changing or deleting the information of the first resource preconfigured for the UE to the core network device while changing or releasing the first resource preconfigured for the UE.

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

The resource processing method provided by the embodiment provides a mechanism for storing and releasing the pre-configured resource information, so that the network equipment can acquire the pre-configured resource information for the idle-state UE after receiving the uplink data transmitted by the idle-state UE, and perform subsequent downlink scheduling, and the pre-configured resource information can be automatically changed or released in the downlink scheduling, thereby improving the flexibility of the network equipment in pre-configuring the resources of the idle-state UE, avoiding network resource waste and improving the utilization rate of the network resources.

Fig. 4 is a second interaction schematic diagram of the resource processing method provided in the present application. The scheme relates to a network device, a UE and a core network device in a network, as shown in fig. 4, and the specific interaction 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 by the network device for the UE is used for the UE to communicate with the 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 202, the network device sends a first message to the core network device, where the first message includes configuration of the first resource and identification of the UE.

In this embodiment, after the network device indicates the first resource to the UE, a first message, that is, the pre-configuration information, is sent to the core network device, where the first message includes the configuration of the first resource and the identifier of the UE. The first message is used for saving 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 the association. It should be noted that, the first message in this embodiment is opaque to the core network device, that is, the core network device may read the preconfiguration information and determine whether the UE performs cell reselection, see step 205 specifically.

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

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

In this embodiment, in one possible case, the UE in the idle state sends uplink data to the network device on the first uplink resource. In another possible scenario, an idle UE sends uplink signaling to a network device through a random access procedure. In yet another possible scenario, an idle state UE sends uplink data or signaling to a network device through a data early transfer procedure (early data transmission, EDT). The first scenario described above is where 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 UE identity and the second cell identity.

In this embodiment, after receiving the uplink data or signaling sent by the UE, the network device may learn the cell information, such as the identifier of the second cell, of the uplink data or signaling sent by the UE. However, since the network device does not store the preconfiguration information of the UE, it cannot be known whether the UE has cell reselection. Thus, the network device sends a second message to the core network device comprising the identity of the UE and the identity of the second cell, so that the core network device determines whether cell reselection of the UE occurs.

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

It should be noted that, the second cell in the present 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 the present 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 indication to the network device, where the first indication is used to indicate to release 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 and the identifier of the first cell corresponding to the identifier of the UE, and when determining that the identifier of the second cell in the second message indicates a different cell than the identifier of the first cell, 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 the core network device determines 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 resources comprise first uplink resources and first downlink resources, and the first downlink resources are used for the network equipment 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 of the above embodiment, and specifically, reference may be made to the above embodiment, which is not repeated here.

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

In this embodiment, after the network device releases 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 by the network device for the UE has failed.

On the basis of the above 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 the idle state. Wherein the second resources include 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 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, so that the core network device stores the latest pre-configuration information of the UE.

The resource processing method provided by the embodiment provides a release mechanism of pre-configured resource information, and the application scene is that the UE is switched among different cells of the same network device, whether the UE performs cell reselection is determined through judgment of the core network device, and when the UE is determined to perform cell reselection, the core network device notifies the network device to release the pre-configured first resource, so that network resource waste is avoided, and the utilization rate of network resources is improved. In addition, after the network device releases the first resource of the first cell, the network device can also configure the second resource of the new cell for the UE, and start a mechanism for storing and releasing the second resource, so as to improve the flexibility of the network device in pre-configuring the resources of the idle state UE.

Fig. 5 is a third interaction schematic diagram of the resource processing method provided in the present application. The scheme relates to a network device, a UE and a core network device in a network, as shown in fig. 5, and the specific interaction 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 a configuration of the first resource and an identification of the UE.

In this embodiment, after the network device indicates the first resource to the UE, a first message, that is, the pre-configuration information, is sent to the core network device, where the first message includes the configuration of the first resource and the identifier of the UE. The first message is used for saving 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 the association. It should be noted that, the first message in this embodiment is transparent to the core network device, that is, the core network device does not read or process the preconfigured information, and only stores the information.

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

Step 301 to step 303 of the present embodiment are the same as step 201 to step 203 of the embodiment of fig. 4, and the detailed description thereof will be omitted herein.

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

In this embodiment, after receiving the uplink data or signaling sent by the UE, the network device may learn the cell information, such as the identifier of the second cell, of the uplink data or signaling sent by the UE. However, since the network device does not store the preconfiguration information of the UE, the identity of the first cell in which the UE is located during the preconfiguration cannot be known, and therefore, the network device sends a third message including the identity of the UE to the core network device to obtain the preconfiguration 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 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 of this embodiment can be regarded as: the core network device 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 identification of the UE.

In this embodiment, after receiving the third message sent by the 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 sends the configuration of the first resource and the identifier of the UE to the network device as the second message, so that the network device determines whether cell reselection occurs to the UE. In contrast to the embodiment of fig. 4, the core network device in this embodiment does not read and process the preconfigured information of the UE.

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

If the third message received from the network device includes an identification of the second cell, the second message may optionally also include an identification 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.

The network equipment acquires the identification of the first cell where the UE is located when the first resource is preconfigured from the second message, and releases the first resource when the identification of the second cell is determined to be different from the identification of the first cell.

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

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

The resource processing method provided by the embodiment provides a release mechanism of pre-configured resource information, an application scene is that the UE is switched among different cells of the same network device, the network device acquires the resource information pre-configured for the UE through the core network device, the network device judges whether the cell reselection occurs to the UE, when the cell reselection occurs to the UE is determined, the network device releases the pre-configured first resource and notifies the core network device to delete the pre-configured resource information of the UE, the network resource waste is avoided, the utilization rate of network resources is improved, meanwhile, the occupation of the memory space of the core network device by invalid resource information is also avoided, and the operation speed of the core network device is improved.

Fig. 6 is a fourth interaction schematic 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 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 first resource pre-configured). As shown in fig. 7, the specific interaction 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 by the second network device for the UE is used for the UE to communicate with the second network device through the first cell when 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 identification of the UE.

In this embodiment, after the second network device indicates the first resource to the UE, a second message, that is, the pre-configuration information, is sent to the core network device, where the second message 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 with the identification of the UE according to the second message. 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 preconfigured information, and only stores the information.

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

In this embodiment, the UE performs cell reselection, and the UE in the idle state sends uplink signaling to the first network device through a random access procedure, or the UE in the idle state sends uplink data or signaling to the first network device through a data early transmission procedure. At this time, the core network device, the first network device, and the second network device have not yet perceived that the UE has undergone cell reselection, and need to be informed through the following steps.

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

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 transmission procedure through the first network device, the third message may include an identification of the UE and uplink data.

Optionally, the third message may further include an identification of a second cell, which may be any cell under coverage of the first network device.

It should be noted that, step 404 of 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 a configuration of the first resource and an identification 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 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 cell reselection occurs to the UE.

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. Wherein the first cell is any cell covered by the second network device.

If the third message received from the first network device includes an identification of the second cell, the first message may optionally also include an identification of the second cell.

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

The first network equipment acquires the identification of a 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 instruct 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 cell reselection occurs to the UE, 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 the configuration releasing the first resources to the second network device.

It should be noted that, the steps 408 and 409 in this embodiment are not limited to the above-described execution sequence, and the steps 409 may be executed first and then the steps 408 may be executed, or the steps 408 and 409 may be executed simultaneously.

Based on the above embodiment, optionally, after step 409, the method may further include: and the core network equipment receives a confirmation message returned by the second network equipment 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 the UE with second resources for the UE to communicate with the first network device through the second cell when in the idle state. Wherein the second resources include 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 configuration of the second resource and the identifier of the UE may also be sent 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 by the embodiment provides a release mechanism of pre-configured resource information, an application scene is that a UE is switched from a first cell of an original network device (second network device) to a second cell of a new network device (first network device), based on the scene, the new network device obtains resource information pre-configured for the UE by the original network device from a core network device, when the new network device determines 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 the resource information pre-configured for the UE by the original network device and instructs the original network device to release the pre-configured resource of the UE. The method enables the original network equipment to timely acquire that the cell reselection occurs to the UE, releases invalid network resources as soon as possible, avoids network resource waste, improves the utilization rate of the network resources, simultaneously also avoids that the invalid resource information occupies the memory space of the core network equipment, and improves the running speed of the core network equipment.

Fig. 7 is a fifth interaction schematic 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 (the network device after the UE performs cell reselection) and a second network device (the original network device), the UE and the core network device, and the specific interaction 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 a configuration of the first resource and an identification of the UE.

In this embodiment, after the second network device indicates the first resource to the UE, a first message, that is, the pre-configuration information, is sent to the core network device, where the first message includes the configuration of the first resource and the identifier of the UE. The first message is used for storing the configuration of the first resource of the UE, namely, the core network equipment associates the configuration of the first resource with the identification of the UE according to the first message and stores the association. It should be noted that, the first message in this embodiment is opaque to the core network device, that is, the core network device may read the preconfiguration information and determine whether the UE performs cell reselection, specifically see step 505.

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 device.

Step 503, the UE in idle state 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 an identity of the UE and an identity of the second cell.

In this embodiment, if the UE initiates a random access procedure through the first network device, the second message includes an identifier of the UE and an identifier of the second cell; if the UE initiates the data early transmission procedure through the first network device, the second message may include an identifier of the UE, an identifier of the second cell, and uplink data. The second cell may be any cell covered by the first network device.

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

Step 505, the core network device determines whether cell reselection occurs to the UE according to the second message.

The difference from the embodiment of fig. 6 is that: the core network device determines whether a cell reselection has occurred for the UE 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 identifier of the UE in the second message, a configuration of a first resource corresponding to the identifier of the UE, where the configuration of the first resource includes the identifier of the first cell. And the core network equipment determines whether the UE performs cell reselection according to the identification of the second cell in the second message and the acquired identification 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 cell reselection occurs to the UE, 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 device sends a first indication to the second network device, and the second network device releases the first resource according to the first indication.

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

On the basis of the above 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 resources include 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-described execution sequence, and the steps 507 and 506 may be executed first, or the steps 506 and 507 may be executed simultaneously.

The resource processing method provided by the embodiment provides a mechanism for releasing pre-configured resource information, an application scene is that a UE is switched from a first cell of an original network device (second network device) to a second cell of a new network device (first network device), based on the scene, the core network device obtains cell information of the UE from the new network device, and when determining that cell reselection occurs to the UE, the core network device deletes the resource information pre-configured for the UE by the original network device, and simultaneously instructs the original network device to release pre-configured resources of the UE. The method enables the original network equipment to timely acquire that the cell reselection occurs to the UE, releases invalid network resources as soon as possible, avoids network resource waste, improves the utilization rate of the network resources, simultaneously also avoids that the invalid resource information occupies the memory space of the core network equipment, and improves the running speed of the core network equipment.
