Attachment method, paging method, device and device

Technical field

Embodiments of the present invention relate to communication technologies, and in particular, to an attachment method, a paging method, an apparatus, and a device.

Background technique

Mobile communications has profoundly changed people's lives, but the pursuit of higher performance mobile communications has never stopped. In order to further improve the performance of mobile communications, new technologies such as faster new wireless access technologies are deployed in the LTE architecture as long-term evolution (English: Long Term Evolution, LTE) technology becomes more mature. New Radio Access Technology (NR) network, in order to meet the needs of rapid deployment, the first phase can only deploy the transmission point of the NR network. Figure 1 is a schematic diagram of the architecture of the non-independently deployed NR network based on the LTE system, as shown in Figure 1. As shown, there is only a transmission point for the NR network, and there is no core network device. An interface exists between the transmission point of the NR network and the evolved Node B (English: evolved Node B, eNB for short). The eNB communicates with the core network device of LTE.

In the LTE system, each LTE cell has a Tracking Area Identifier (TAI), and each TAI can correspond to multiple LTE cells. The user equipment (English: User Equipment, UE for short) initiates an attach procedure after the device is powered on. After receiving the attach request, the core network device configures a TAI list for the UE for the core network to page the UE. In the above-mentioned non-independently deployed NR network architecture, the NR cell can reuse the TAI of the LTE cell. Since there is no direct interface between the core network device and the transmission point of the NR network, when the core network device pages the UE, the core The network device sends a paging message to the eNB, where the paging message carries a TAI list configured by the core network device for the UE, and the eNB determines to page the UE in the corresponding cell according to the TAI list.

However, there is currently no suitable paging method for UEs that are capable of communicating over the NR network.

Summary of the invention

The embodiments of the present invention provide an attaching method, a paging method, a device, and a device, which are used to solve the problem that a suitable paging method is not available for a UE having the capability of performing communication using an NR network.

A first aspect of the present invention provides a paging method, which is applied to a core network device, and includes:

The core network device sends a paging message to the UE to the base station; the paging message carries a MAI list of the NR network configured by the core network device for the UE;

The MAI list includes at least one MAI, where the MAI is used to identify a mobile area of the NR network, and the mobile area includes at least one NR cell.

Optionally, the paging message further carries a TAI list of the UE.

In the solution, when the downlink service of the UE is to be sent on the network side, the core network device carries the TAI list of the LTE network configured for the UE and the MAI list of the NR network in the paging message sent by the base station, or only Carry a list of MAIs. The TAI is an identifier of a tracking area in the LTE system, and each LTE cell corresponds to one TAI, and one TAI may include multiple LTE cells. The TAI generally has a public land mobile network identifier and a tracking area code. In the NR network in this solution, the solution provides a concept of a mobile area, which is similar to a tracking area in LTE. The mobile area also has a plurality of NR cells, which are used to locate an idle state UE, and include multiple When the NR cell moves in the mobile area, the UE in the idle state does not need to interact with the core network, that is, it does not need to trigger the update of the cell. The MAI may be a public land mobile network identifier and a moving area (English: Moving Area, abbreviated as: MA) code, or may be in other forms.

In this solution, the core network device refers to a core network device in an LTE network, for example, a mobility management entity (English: Mobility Management Entity, MME for short).

After the core network configures the MAI list for the UE, when the UE is paging, the base station may page the corresponding UE according to the MAI list configured by the core network device for the UE, and implement paging of the NR network to the UE with the NR network capability. During a specific paging, the base station sends a paging message to the transmission point of the relevant NR network according to the MAI list to indicate that the transmission point of the NR network pages the UE on the air interface. For these UEs, only paging of the NR network can be performed, and paging of the LTE network is not performed, and the paging load is reduced.

In a specific implementation manner, the core network device acquires NR capability indication information of the UE, where the NR capability indication information is used to indicate that the UE supports an NR network.

The core network device configures the MAI for the UE according to the NR capability indication information. List.

Optionally, the core network device may also configure a TAI list of the LTE network for the UE while configuring the MAI list for the UE according to the NR capability indication information.

The core network device generally configures the MAI list for the UE according to the capability of the UE supporting the network before the paging of the UE, that is, the core network device needs to acquire the capability of the UE in advance, and the solution mainly refers to supporting the NR network communication. The capability, that is, the NR capability indication information of the UE needs to be obtained, and after determining that the UE supports the NR network communication, the core network configures the MAI list for the UE, and the MAI list includes at least one MAI. The configuration of the MAI list by the core network device according to the capability indication information of the UE may be performed when the UE first attaches, or may be performed after the TAI list is configured, and after obtaining the indication information that the UE supports the NR network, when the update is performed. There is no limit to this.

On the basis of the foregoing solution, the core network device acquires the NR capability indication of the UE, including:

The core network device receives an attach request message sent by the base station; the attach request message includes NR capability indication information of the UE.

or,

The core network device receives the NR capability indication information of the UE sent by the base station.

The meaning of the solution is that the core network device obtains the NR capability indication information of the UE by using at least two modes. The other is that the core network device receives the NR capability indication information of the UE that is sent by the base station, and the other is After the TAI list of the LTE network configured by the core network device, the UE obtains the NR capability indication information of the UE, and then reports the information to the core network device.

Further, after the core network device configures the MAI list for the UE according to the capability indication information of the UE carried in the attach message, or after the TAI list and the MAI list, the core network device sends an attach accept message to the base station; The attach accept message carries the MAI list configured for the UE, or carries the TAI list and the MAI list.

The meaning is that the core network device needs to notify the UE through the base station through the attach accept message, so that the UE can be paged or perform data interaction on the network uplink.

In another implementation manner of the first aspect, the core network device receives the NR capability indication information of the UE that is sent by the base station;

The core network device sends an update message to the base station; the update message includes: the core network device configuring a MAI list, or a MAI list and a TAI list, for the UE according to the NR capability indication information of the UE.

In the meaning of the scheme, if only the TAI list of the LTE network is configured when the UE is attached, the core network device determines, by the NR capability indication information of the UE reported by the base station, that the UE supports the NR network, and the core network. The device needs to configure the MAI list for the UE. At this time, the base station does not attach the accept message, but updates the message. The update message is used to update the MAI list, and the optional core network device can also perform configuration update on the TAI list. After the UE is found to support the NR network, the core network device configures the MAI list for the UE to implement paging of the NR to the UE.

On the basis of any of the above solutions, before the core network device sends a paging message to the UE to the base station, the method further includes: the core network device receiving an S1 interface setup request message sent by the base station; The S1 interface setup request message includes: a cell identifier of all NR cells managed by a transmission point of an NR network having an interface with the base station, and a MAI corresponding to each NR cell, which may also be a transmission point of the NR network. All MAIs and NR cell identifiers corresponding to each MAI;

The core network device returns an S1 interface setup response message to the base station.

The meaning is that the S1 interface needs to be established between the core network device and the base station before the paging of the UE is performed. The specific manner is: the core network device receives the S1 interface setup request message sent by the base station; The establishment request message includes a cell identifier of all NR cells and a MAI corresponding to each NR cell of the transmission point of the NR network that has an interface with the base station, and may also be all MAIs under the transmission point of the NR network. An NR cell identifier corresponding to each MAI; the core network device returns an S1 interface setup response message to the base station.

The S1 interface is an interface between the base station packet core networks of the LTE network. The LTE system is divided into a radio access network and a core network. When establishing the S1 interface, based on the establishment process of the existing S1 interface, the base station also needs to report the MAI of the cell managed by the transmission point of all NR networks having an interface with the base network device to the core network device, so that the core network The device can configure the MAI list of the UE.

A second aspect of the present invention provides a paging method, which is applied to a base station side, and includes:

Receiving, by the base station, a paging message sent by the core network device, where the paging message carries a MAI list of the NR network of the UE, where the MAI list includes at least one MAI, and the MAI is used for marking A mobile area of the NR network is identified, the mobile area including at least one NR cell.

The base station pages the UE according to the paging message.

Optionally, the paging message further carries a TAI list of the UE.

Optionally, the base station paging the UE according to the paging message, including:

The base station forwards the paging message to a transmission point of a corresponding NR network according to the MAI list.

In this solution, when the downlink service of the UE exists on the network side, the paging message sent by the core network device received by the base station may include only the MAI list, or may include the TAI list and the MAI list, indicating the UE. The possible existence range, the base station determines that the MAI including the own MAI exists in the MAI list, and forwards the paging message to the transmission point of the corresponding NR network, and the paging message forwarded to the transmission point of the NR network is used to indicate the NR. The transmission point of the network may be transmitted on the air interface of the UE. If the paging message sent by the core network device only carries the MAI list, the paging message sent by the base station to the transmission point of the NR network may include a MAI list. The MAI list may not be included; if the paging message sent by the core network device carries the MAI list and the TAI list, the paging message forwarded by the base station to the transmission point of the NR network may include a MAI list and a TAI list, or only the MAI list. It is also possible not to include the MAI list and the TAI list.

In this solution, there is an interface between the base station and the transmission point of the NR network, that is, when the transmission point is set, an interface is established between it and the base station.

The scheme ensures that the UE supporting the NR network can also be paged, thereby effectively improving the paging success rate of the UE supporting the NR network.

Specifically, before the receiving the paging message sent by the core network device, the method further includes:

The base station sends an attach request message to the core network device; the attach request message includes NR capability indication information of the UE; and the NR capability indication information is used to indicate that the UE supports the NR network;

Receiving, by the base station, an attach accept message returned by the core network device, where the attach accept message carries a MAI list configured by the core network device according to the NR capability indication information of the UE, or carries the core The TAI list and the MAI list configured by the network device for the UE.

The meaning of the scheme is that before paging the UE, the base station needs to send an attach request message to the core network device, so that the UE can attach to the core network, and the base station sends the core network to the core network. The NR capability indication information of the UE needs to be carried in the NS capability indication information, and the manner in which the eNB obtains the NR capability indication information of the UE includes at least the following two types:

The first method is: before the base station sends an attach request message to the core network device, the method further includes: the base station receiving an attach request message sent by the UE, where the attach request message includes an NR capability of the UE Instructions.

The second way is: before the base station sends the attach request message to the core network device, the base station receives an attach request message sent by the transmission point of the NR network; the base station adds the NR of the UE in the attach request message. Capability indication information.

It can be understood that, in the process of attaching the UE, the UE may directly send an attach request message to the base station, or the UE may send an attach request message to the base station through the transmission point of the NR network to initiate the attach, if the UE directly initiates the attach on the base station, The UE may directly carry the NR capability indication information in the attach request message; if the UE initiates the attach at the transmission point of the NR network, the base station may determine that the UE supports the NR network communication, and the base station needs to increase the NR capability of the UE in the attach request message. The indication information is then sent to the core network device. The NR capability indication information is used to inform the core network device that the attach request message is an air interface from the NR network, that is, the UE has the capability of NR network communication.

Optionally, the method further includes:

Sending, by the base station, a capability query message to the UE;

Receiving, by the base station, the NR capability indication information that is sent by the UE, where the NR capability indication information is used to indicate that the UE supports the NR network;

Sending, by the base station, the NR capability indication information of the UE to the core network device;

The base station receives an update message returned by the core network device, and the update message carries the core network device to configure a MAI list, or a MAI list and a TAI list, for the UE according to the NR capability indication information of the UE.

The solution is different from the foregoing solutions. When the base station sends an attach request message to the core network device, the base station does not carry the NR capability indication information of the UE, but after the core network device configures the TAI list for the UE, the base station passes. The UE is queried to obtain the UE supporting the NR network, and then the core network is informed that the UE supports the NR network, so that the core network configures the MAI list for the UE, and then sends an update message to the UE through the base station. In the above process, the core network device can also reconfigure the TAI list while configuring the MAI list, that is, the MAI list and the TAI list can be simultaneously performed. Updates effectively reduce the signaling load on core network devices.

Optionally, before the receiving, by the base station, the paging message sent by the core network device, the method further includes:

The base station acquires the cell identifier of all NR cells managed by the transmission point of the NR network that has an interface with the base station, and the MAI corresponding to each NR cell, and may also be all MAI and each of the transmission points of the NR network. NR cell identifier corresponding to each MAI;

Sending, by the base station, an S1 interface setup request message to the core network device, where the S1 interface setup request message includes a cell identifier of each NR cell managed by a transmission point of an NR network that has an interface with the base station, and each The MAI corresponding to the NR cell may be in the form of all the MAIs under the transmission point of the NR network and the NR cell identifier corresponding to each MAI;

The base station receives an S1 interface setup response message returned by the core network device.

In any of the above solutions, the base station needs to establish an S1 interface with the core network device in advance, and carries the MAI of the NR cell managed by the transmission point of the NR network in the setup interface request, so that the core network configures the MAI list for the UE.

A third aspect of the present invention provides a paging method, which is applied to a transmission point side of an NR network, and specifically includes:

The transmission point of the NR network receives the paging message sent by the base station; the paging message is used to indicate that the transmission point of the NR network pages the user equipment UE;

The transmission point of the NR network pages the UE on an air interface.

The meaning is that the transmission point advertises the UE on the air interface according to the indication of the base station, so that in the non-independently deployed NR network, the MAI list can be configured through the core network device to implement paging for the UE.

Optionally, the method further includes: receiving, by the transmission point of the NR network, an attach request message sent by the UE; and transmitting, by the transmission point of the NR network, the attach request message to the base station.

The transmission point of the NR network may also be forwarded to the base station according to the attach request sent by the UE, so that the base station forwards the attach request message to the core network device, so as to implement attachment of the UE to the core network device.

A fourth aspect of the present invention provides an attaching method, where the solution is applied to a core network device side, including:

The core network device receives an attach request message sent by the base station; the attach request message includes a new radio access technology NR capability indication information of the UE, where the NR capability indication information is used to indicate that the UE supports the NR network;

The core network device configures, according to the NR capability indication information of the UE, a mobile area identifier MAI list of the NR network for the UE;

The core network device sends an attach accept message to the base station; the attach accept message carries the MAI list;

Optionally, the core network device may further configure a TAI list for the UE; and the attach accept message further carries the TAI list.

The present invention provides an attach procedure for a UE with an NR network communication capability to a core network device, and the core network device receives an attach request message sent by a base station of the LTE network, where the NR capability indication information for indicating that the UE has NE network communication is included. Then, the UE is configured with a MAI list, or a MAI list and a TAI list, which is similar to the tracking area in LTE. The mobile area is also composed of multiple NR cells for locating the idle state UE, and includes multiple NRs in the mobile area. When the cell moves in the mobile area, the UE does not need to interact with the core network, that is, does not need to trigger the cell update. After receiving the attach accept message sent by the core network device, the UE with the NR network communication capability can be successfully paged when there is downlink service on the network side.

Optionally, before the core network device obtains the new radio access technology NR capability indication of the user equipment UE, the method further includes:

Receiving, by the core network device, an S1 interface setup request message sent by the base station; where the S1 interface setup request message includes a cell identifier of each NR cell managed by a transmission point of an NR network that has an interface with the base station, and The MAI corresponding to the NR cells may be in the form of all the MAIs under the transmission point of the NR network and the NR cell identifiers corresponding to each of the MAIs;

The core network device establishes an S1 interface with the base station according to the S1 interface setup request message, and returns an S1 interface setup response message to the base station.

The above two solutions are all solutions for the initial attach procedure of the UE. During the initial attach process, the core network device receives the capability indication information of the NR carried by the base station in the attach request message, and the core network device according to the capability of the NR The indication information is configured for the UE to configure the MAI list or the TAI list and the MAI list, that is, the configuration of the LTE network and the NR network is completed at the same time, which effectively saves signaling overhead, and can successfully page the UE when the UE has downlink services.

The base station sends the attach accept message to the UE.

Optionally, the attach accept message further carries a TAI list configured by the core network device for the UE.

In this solution, when each MAI corresponds to multiple NR cells, the idle state UE in the mobile area does not need to interact with the core network device when moving between the NR cells.

Optionally, before the sending, by the base station, the attach request message to the core network device, the method further includes:

Receiving, by the base station, an attach request message sent by the UE; the attach request message includes NR capability indication information of the UE;

or,

The base station receives an attach request message sent by a transmission point of the NR network, and adds an NR capability indication information of the UE therein.

The meaning of the scheme is that the base station acquires the NR capability indication information of the UE, including at least two modes. One is that the base station receives the NR capability indication information that the UE sends the attached message to carry the UE, and the other is that the base station receives the NR. The attach request message sent by the transmission point of the network may determine that the UE supports the NR network, and the base station adds the NR capability indication information of the UE to the core network device after adding the NR capability indication information of the UE.

The base station sends the update message to the UE.

Optionally, the update message further includes a tracking area identifier TAI list of the Long Term Evolution (LTE) network configured by the core network device for the UE.

In this solution, different from the foregoing attachment method, after the base station obtains the NR capability of the UE, the base network device is notified of the NR capability of the UE, and the core network device obtains the NR capability of the UE, and then configures the MAI list for the UE. The message sent by the core network device is an update message, which is used to update the MAI list and or the TAI list of the UE, so that the UE with the NR network communication capability can be paged on the air interface of the transmission point of the NR network.

A UE with the NR network capability can reside in the LTE cell or the NR cell. The solution is not limited according to the cell camping policy. The 4G UE can only reside in the LTE cell.

2 is a schematic diagram showing a specific implementation of a non-independently deployed NR network based on an LTE system. In order to improve the network transmission rate, the NR network can communicate in a high frequency band, which results in the coverage of the NR cell is smaller than the existing LTE cell operating in the low frequency band, as shown in FIG. 2, within an LTE cell coverage area. There will be multiple NR cells.

According to the architecture provided in FIG. 1 and FIG. 2 above, the eNB considers the NR cell as its own cell, and the eNB does not forward the paging message to the transmission point of the NR network, and the UE does not receive the UE in the NR cell. The paging message to the network side causes the paging to fail. Another solution is that the eNB treats the NR cell under its coverage as another cell of the base station, and the eNB forwards the paging message to the transmission point of the NR network, and then the paging point is used to page the UE on the air interface. At the same time, even for a legacy UE that does not support the NR, the network side sends a paging message to the legacy UE in the NR network. At this time, there may be multiple NR cells in one LTE macro zone, plus the LTE cell. In itself, the number of cells is large, and paging is performed in each cell, which causes an increase in paging load, causing congestion of paging messages and reducing the success rate of paging. In fact, according to the above two methods, The NR network communication capability UE performs efficient paging. Therefore, the present application proposes a more reasonable paging method and attachment method to implement paging for the UE having the NR network communication capability.

The technical solution of the present application is applicable to any non-independently deployed network communication system, that is, the newly set wireless communication technology cannot work independently, and needs to serve the user equipment with new wireless communication capability based on the existing network equipment and the core network equipment. In the solution of the present application, the NR network is taken as an example, and the base station and the 4G core network are used to provide services for the UE supporting the NR network. The network elements involved in the solution include: a core network device, a base station, a transmission point of the NR network, and a user. The device, which may also be called a terminal or a terminal device, may be a mobile phone, a tablet computer, a personal digital assistant (English: Personal Digital Assistant, PDA for short), a sales terminal (English: Point of Sales, POS for short). A device that requires wireless communication, such as an on-board computer, and the specific device type is not limited.

This application proposes the concept of a moving area (English: Moving Area, abbreviated as MA) for the NR network system. The tracking area (English: Tracking Area, TA for short) in the MA and the LTE network is similar to the location area and routing area in the 2G/3G network. The mobile area is composed of a plurality of NR cells, and is used for locating the idle state UE. When the UE supporting the NR network in the idle state moves in the mobile area, it does not need to interact with the core network, that is, the mobile area does not need to be moved. Update. The mobile area is represented by a mobile area identifier (MAI). The MAI is composed of a PLMN ID and a mobile area code (English: Moving Area Code, MAC address for short), and may be other forms.

3 is a flowchart of a first embodiment of a paging method according to the present invention. As shown in FIG. 3, when a downlink service of a UE is to be sent on a network side, the core network device needs to perform paging on the UE, and the paging method is specific. The transmission points involving the core network equipment, the base station, and the NR network are specifically implemented as follows:

S101: The core network device sends a paging message to the UE to the base station, where the paging message carries a MAI list of the NR network configured by the core network device for the UE.

In this step, when the downlink service of the UE is to be sent on the network side, the paging message sent by the core network device to the base station carries the TAI list of the LTE network and the MAI list of the NR network previously configured for the UE, and the TAI is The identifier of the tracking area in the LTE system, each LTE cell has a TAI, and one TAI may include multiple LTE cells. The TAI generally has a public land mobile network identifier and a tracking area code. In the NR network in the present scheme, the MAI list includes at least one MAI, the MAI is used to identify a mobile area of the NR network, and the mobile area includes at least one NR cell. The solution provides a concept of a mobile area, which is similar to a tracking area in LTE. The mobile area is also composed of multiple NR cells. Each MAI list may include one or more MAIs, and each MAI may be used to identify multiple NR cells, but each has only one unique MAI.

Before the core network device pages the UE, the MAI list and the TAI list need to be configured for the UE in advance, so that the paging can be completed based on the MAI list and the TAI list of the UE. A specific manner is that the core network device configures the foregoing MAI list according to the NR capability indication information of the UE.

The core network device first needs to obtain the NR capability indication information of the UE. The NR capability indication information is used to indicate that the UE supports the NR network, that is, the UE can communicate by using the NR network, and the specific manner for the core network device to obtain the NR capability indication information of the UE includes at least the following:

The first type: the core network device receives the attach request message sent by the base station, where the message carries the NR capability indication information of the UE;

The second type: after the base station sends the TAI list configured by the core network device to the UE, the base station acquires the NR capability of the UE, and reports the NR capability indication information of the UE to the core network device.

After the core network device obtains the NR capability indication information of the UE, the core network device configures the TAI list and the MAI list for the UE according to the NR capability indication information, so as to perform subsequent communication.

The core network device initiates paging for the UE with the downlink service based on the configured TAI list and the MAI list, that is, sends a paging message to the base station.

Optionally, in the solution, the core network device may only carry the MAI list in the paging message, that is, after the core network device obtains the NR capability indication information of the UE by using the foregoing manner, the core network device is configured according to the NR capability. The indication information is that the MAI list is configured only for the UE, so that the NR-capable UE can be subsequently paged.

S102: The base station pages the UE according to the paging message.

In this step, the base station receives the paging message sent by the core network device, where the paging message includes a TAI list and a MAI list. When the base station finds that the TAI list includes its own TAI, it is in the corresponding LTE cell. The UE initiates paging. In addition, the base station determines, according to the MAI list in the paging message received from the MME, whether to forward the paging message to the transmission point of the NR network that has the interface with the MME. The specific determining manner may be: the base station according to the paging message a MAI list, checking whether there is a MAI of a cell under the transmission point of the NR network connected to the base station in the MAI list, and if present, forwarding the paging message to a transmission point of the NR network in the list in which the MAI of the cell exists . The paging message of the transmission point forwarded to the NR network may carry only the MAI list without carrying the TAI list, or may not carry the TAI list and the MAI list.

If the paging message is sent to the transmission point of the NR network, after the transmission point of the NR network receives the paging message sent by the base station, the UE is paged on the corresponding NR cell to complete the paging process.

Optionally, if the paging message carries only the MAI list, after receiving the paging message, the base station directly forwards the paging message carrying the MAI list to the transmission point of the corresponding NR network, so that the NRs are The transmission point of the network pages the UE on the corresponding air interface. The paging message that the base station forwards to the transmission point of the NR network may also not carry the MAI list, which is not limited.

In this embodiment, for the core network device, the core network device sends a paging message to the UE to the base station when the UE has a downlink service, where the message carries a MAI list, or a TAI list and a MAI list, for the base station. For example, the base station receives the paging message sent by the core network device, and pages the UE according to the MAI list or the TAI list and the MAI list.

In the paging method provided by the embodiment, in the non-independently deployed NR network system, the core network device uses the NR capability indication information of the UE to simultaneously configure the TAI list under the LTE and/or the MAI list under the NR network to reduce the MAI list. The MME signaling load, and the base station can forward the paging message to the transmission point of the corresponding NR network according to the MAI list of the UE, so as to implement paging of the UE with the NR network communication capability under the NR network. Compared with the aforementioned scheme, the NR network capability is guaranteed. The UE can also be paged on the NR cell; and only paging the NR cell for the UE with the NR network capability, reducing the paging load on the NR cell, effectively improving the paging success of the UE supporting the NR network. Rate, which enables paging optimization in non-independently deployed NR systems.

On the basis of the first embodiment, before the paging of the UE, the UE must first attach, and the base station sends an attach request message to the core network device, and then the core network device configures the MAI list for the UE according to the attach request message, or The MAI list and the TAI list are then paged when the UE has downlink services. The following describes the attaching method and the paging method proposed by the present application through several specific examples.

4 is a schematic diagram of a signaling interaction process according to Embodiment 2 of the paging method of the present invention. As shown in FIG. 4, in the process of performing network deployment, first, an S1 interface needs to be established between an eNB and a core network device, and an NR network is established. The transmission point establishes an X5 interface with the eNB. During the establishment of the X5 interface, the transmission point of the NR network informs the eNB of all the NR cell identifiers it manages and its corresponding MAI. Optionally, the notification can also be MAC. During the establishment of the S1 interface, based on the existing S1 interface establishment process, the eNB needs to inform the core network device of the NR cell identity of all NR network transmission points with which the interface exists and its MAI. Optionally, the notification can also be MAC. After the network is deployed, the UE first needs to perform network attachment, and then the core network device can page the UE when there is downlink service. The process of initiating attachment by the UE under the transmission point of the NR network and the subsequent paging process are described below. The specific implementation steps are:

S201: The UE sends an attach request message to a transmission point of the NR network.

In this step, the UE needs to perform an attach procedure in the process of initially accessing the network, and the UE with the NR network capability can directly initiate an attach request under the transmission point of the NR network.

S202: The transmission point of the NR network sends the attach request message to the base station.

In this step, since there is no direct interface between the transmission point of the NR network and the core network device, the transmission point of the NR network forwards the attach request message to the eNB after receiving the attach request message sent by the UE.

S203: The base station adds the NR capability indication information of the UE to the attach request message, and sends an attach request message after the NR capability indication information is added to the core network device.

In this step, after receiving the attach request message forwarded by the transmission point of the NR network, the eNB adds an NR capability indication information to the attach request message, and sends the NR capability indication information to the core network device. The NR capability indication information is used to notify the core network device, and the attach request message is from the NR network. The air interface, that is, the UE that sends the attach request message, has an NR network capability.

Optionally, the NR capability indication information may be added by the UE to the attach request message and finally reported to the core network device in step S201.

S204: The core network device configures a TAI list and a MAI list for the UE according to the NR capability indication information.

In this step, after receiving the attach request message, the core network device learns that the UE is an NR UE by using the NR capability indication information in the attach request message, and configures a MAI list for the UE according to the NR capability indication information. And configuring the TAI list at the same time, and transmitting the MAI list and the TAI list to the eNB through an attach accept message. The MAI list contains at least one MAI. In this solution, the core network device is configured independently of the NR capability indication information when configuring the TAI list, but adopts an existing configuration method of the tracking area of the LTE network.

Optionally, the core network device may also configure the MAI list only for the UE.

In this solution, the core network device configures the TAI list and the MAI list for the NR network-capable UE at the same time, or only configures the MAI list, mainly considering that there is overlapping coverage between the NR cell and the LTE cell, and the LTE cell can ensure continuous coverage. The NR cell may be deployed in a dotted manner and cannot guarantee continuous coverage. At this time, the idle state UE may enter the LTE cell from one NR cell during the mobile process, and then re-enter the NR cell. If the core network device only configures the MAI list at this time, when the UE enters the LTE cell, the TAU on the LTE cell is triggered, and when the NR cell is entered, the mobile area update MAU process on the NR cell is triggered, in the LTE cell. Frequent movements with the NR cell cause an increase in the signaling load of the core network device. Considering that both the LTE cell and the NR cell are managed by the core network device (for example, the MME of the LTE network), in order to reduce the signaling load, when the UE is determined to be the NR UE, the TAI list and the MAI can be simultaneously configured for the UE. List. In this way, the NR UE can move within the LTE cell and the NR cell corresponding to the TAI list and the MAI list without interacting with the core network device.

S205: The core network device sends an attach accept message carrying the TAI list and the MAI list to the base station.

In this step, the core network device carries the configured TAI list and the MAI list in the attach and receive message to the eNB. Optionally, when the core network device only configures the MAI list for the UE, the attach accept message carries only the MAI list.

In the above S204 and S205, the core network device receives the attach request message sent by the base station; the attach request message includes the NR capability indication information of the UE, and the core network device according to the The NR capability indication information of the UE in the attach request message configures the TAI list and the MAI list, or the MAI list, and sends an attach accept message to the base station; the attach accept message carries the TAI configured for the UE The list and the MAI list, or the MAI list, implement attachment configuration of the UE.

S206: The base station forwards the attach accept message carrying the TAI list and the MAI list to the transmission point of the NR network.

In this step, the eNB sends an attach accept message received from the core network device to the transmission point of the corresponding NR network, where the attach accept message carries the TAI list and the MAI list configured by the MME for the NR UE. Optionally, the attach accept message may only carry the MAI list.

S207: The transmission point of the NR network forwards the attach accept message carrying the TAI list and the MAI list to the UE.

In this step, the transmission point of the NR network receives the attach accept message of the core network device replies to the UE from the eNB, and forwards the message to the UE, where the attach accept message carries the TAI list configured by the core network device for the UE. And the MAI list. Optionally, the attach accept message may only carry the MAI list.

S208: The core network device sends a paging message to the UE to the base station, where the paging message carries a TAI list and a MAI list.

In this step, when the UE has a service, the core network device pages the UE, and sends a paging message to the corresponding eNB according to the TAI list and the MAI list previously configured for the UE, where the paging message is sent. Carrying a TAI list and a MAI list configured by the core network device for the UE. Alternatively, the paging message only carries the MAI list configured by the core network device for the UE.

S209: The base station pages the UE according to the TAI list.

In this step, the eNB receives the paging message sent by the core network device, and the paging message has a TAI list. When the eNB finds that the TAI list contains its own TAI, it initiates paging to the UE on the corresponding LTE cell.

S210: The base station sends a paging message to the transmission point of the NR network according to the MAI list.

In this step, the eNB decides whether to forward the paging message to the transmission point of the NR network with which the interface exists, according to the MAI list in the paging message received from the core network device. The paging message forwarded at this time may only carry the MAI list without carrying the TAI list, or may not carry the TAI list and the MAI list.

S211: The transmission point of the NR network pages the UE on the air interface.

After receiving the paging message sent by the eNB, the transmission point of the NR network pages the UE on the corresponding NR cell.

Optionally, if the paging message carries only the MAI list, after receiving the paging message, the base station does not perform paging on the air interface, but forwards the MAI list to the transmission point of the corresponding NR network. So that the transmission points of the NR networks page the UE on the corresponding air interface.

In the paging method provided by this embodiment, in a non-independently deployed NR network system, a UE having the capability of communicating using the NR network can trigger an attach procedure through a transmission point of the NR network. The core network device reduces the signaling load of the core network device by identifying whether the UE has the NR capability for the UE to simultaneously configure the MAI list under LTE, or the TAI list and the MAI list under the NR network. The eNB forwards the paging message to the transmission point of the corresponding NR network according to the MAI list configured by the core network device for the UE, so as to implement paging to the UE under the transmission point of the NR network. Compared with the existing scheme, it is ensured that the NR UE can also be paged on the NR cell; and paging is only performed for the NR UE in the NR cell, the paging load on the NR cell is reduced, and the paging of the NR UE is provided. Success rate; in addition, the TAI list in LTE is configured simultaneously with the MAI in the NR network, which can effectively reduce the signaling load of the core network device. Paging optimization in a non-independently deployed NR network system is achieved.

FIG. 5 is a schematic diagram of a signaling interaction process according to Embodiment 3 of the paging method of the present invention. As shown in FIG. 5, in the process of performing network deployment, first, an S1 interface needs to be established between an eNB and a core network device, and an NR network is established. An X5 interface is established between the transmission point and the eNB. The specific manner of establishing the S1 interface and the X5 interface is similar to that of the second embodiment. In this solution, the UE may send an attach request message to the base station to trigger the attach process. The specific implementation steps are as follows:

S301: The UE sends an attach request message to the base station, where the attach request message carries the NR capability indication information.

In this step, different from the second embodiment, in this embodiment, the UE initiates an attach request on the LTE cell. If the UE is a 4G UE, it is the same as the existing LTE technology. If the UE is an NR capable UE, the NR capability indication information is added to the attach request message.

The subsequent descriptions of this embodiment are only for UEs with NR network capabilities.

S302: The base station sends the attach request message to the core network device.

In this step, the eNB uploads an attach request message with NR capability indication information uploaded by the UE. Send to the core network device.

S303: The core network device configures a TAI list and a MAI list for the UE according to the NR capability indication information.

In this step, after the core network device receives the attach request message, the NR capability indication message in the attach request message is used to learn that the UE is an NR UE, and the TAI list and the MAI list are simultaneously configured for the UE. The attach accept message is sent to the eNB. The MAI list contains at least one MAI.

S304: The core network device sends an attach accept message carrying the TAI list and the MAI list to the base station.

S305: The base station forwards an attach accept message carrying the TAI list and the MAI list to the UE.

S306: The core network device sends a paging message to the UE to the base station, where the paging message carries a TAI list and a MAI list.

S307: The base station pages the UE according to the TAI list.

S308: The base station sends the paging message to the transmission point of the NR network according to the MAI list.

S309: The transmission point of the NR network pages the UE on the air interface.

In the process of the subsequent S304 to S309, as in the foregoing embodiment, in this step, when the UE has a service, the core network device pages the UE according to the TAI list and the MAI list previously configured for the UE. Sending a paging message to the corresponding eNB, where the paging message carries a TAI list and a MAI list configured by the core network device for the UE. The eNB receives the paging message sent by the core network device, and the paging message has a TAI list. When the eNB finds that the TAI list contains its own TAI, the eNB initiates paging on the air interface. The eNB decides whether to forward the paging message to the transmission point of the NR network with which the interface exists, according to the MAI list in the paging message received from the core network device. The paging message forwarded at this time may only carry the MAI list without carrying the TAI list, or may not carry the TAI list and the MAI list. After receiving the paging message sent by the eNB, the transmission point of the NR network pages the UE on the air interface.

Optionally, in this embodiment, similar to the foregoing embodiment shown in FIG. 4, the core network device may configure the MAI list only for the UE in the UE attaching process. In this case, when the UE has downlink services, When the UE performs paging, the paging message sent by the core network device to the base station only carries the MAI list. After receiving the paging message, the base station does not perform paging on the air interface (step S307 does not need to be performed), but The paging message is forwarded to the transmission point of the corresponding NR network, so that the transmission point of the NR network pages the UE on the corresponding air interface.

In the paging method provided in this embodiment, in a non-independently deployed NR network system, the NR UE can initiate an attach procedure through the eNB, and the core network device configures the MAI list for the UE by identifying whether the UE has the NR network capability, or configures the LTE under the same time. The TAI list and the MAI list under the NR network reduce the core network device signaling load. The eNB forwards the paging message to the transmission point of the corresponding NR network according to the MAI list configured by the core network device for the UE, so as to implement paging of the NR network UE under the transmission point of the NR network. It is ensured that the NR UE can also be paged on the NR cell, and paging only on the NR cell for the NR UE, reducing the paging load on the NR cell, and providing the paging success rate of the NR UE; in addition, in LTE The TAI list is configured simultaneously with the MAI in the NR network, which can effectively reduce the signaling load of the core network device.

FIG. 6 is a schematic diagram of a signaling interaction process in a fourth embodiment of the paging method according to the present invention. As shown in FIG. 6, when the UE of the third embodiment initiates an attach request on an LTE cell, the attach request in the existing LTE system is performed. The message is modified, and the NR capability indication message of the UE is added. This embodiment provides a scheme for not modifying the LTE attach request message, and provides a paging method for the UE of the NR network, which is similar to the foregoing embodiment. The S1 interface and the X5 interface are set up in the network deployment process. The specific implementation method is consistent with the previous embodiment. The specific implementation steps of the paging method provided in this embodiment are as follows:

S401: The UE sends an attach request message to the base station.

In this step, the UE initiates an attach request message on the LTE cell, and the attach request message does not include the NR capability indication information of the UE, as in the existing LTE technology.

S402: The base station sends the attach request message to the core network device.

In this step, the eNB sends an attach request message sent by the UE to the core network device.

S403: The core network device configures a TAI list for the UE.

S404: The core network device sends an attach accept message carrying the TAI list to the base station.

After receiving the attach request message, the core network device configures a TAI list for the UE, and returns an attach accept message to the UE, and sends the message to the eNB. The attachment accept message includes a TAI list.

S405: The base station forwards the carry TAI list attach accept message to the UE.

After receiving the attach accept message sent by the core network device, the eNB sends the attach accept message to the UE.

The above steps S401 to S405 are the attachment processes defined in the LTE system.

S406: The core network device acquires the NR capability indication information of the UE, where the NR capability indication information is used to indicate that the UE supports the NR network.

In this embodiment, since the UE is initially attached, the core network device side does not have the capability information of the UE, and thus acquires the capability of the UE. The UE capability interaction process is the same as the UE capability interaction process in the existing LTE, but only when the UE reports the capability, the UE supports the NR network capability indication.

Specifically, the eNB may initiate an inquiry to the UE, and report the capability information of the UE to the core network device. If it is a 4G UE, the UE capability interaction process is the same as the existing LTE system technology; if it is a UE supporting the NR network, the NR capability indication information of the UE needs to be added in the UE capability information, that is, the core network device knows The UE is a UE supporting an NR network.

S407: The core network device configures a TAI list and a MAI list for the UE according to the NR capability indication information.

After receiving the attach request message, the core network device learns that the UE is an NR UE by using an NR capability indication message in the attach request message, and may simultaneously configure a TAI list and a MAI list for the UE.

S408: The core network device sends an update message carrying the TAI list and the MAI list to the base station.

In this step, the core network device obtains the NR capability indication information of the UE by using the UE capability interaction process. If the UE is an NR UE, the MAI list is configured for the UE, and an update message is sent to the eNB, where the update message includes The TAI list and the MAI list configured by the core network device for the UE.

Optionally, in this solution, after obtaining the NR capability indication information, the core network device may only configure the MAI list for the UE, and may also reconfigure the update of the TAI list, which is not limited.

S409: The base station forwards the update message carrying the TAI list and the MAI list to the UE.

In this step, after receiving the update message with the TAI list and the MAI list sent by the core network device, the eNB sends the update message directly to the UE.

S410: The core network device sends a paging message to the UE to the base station, where the paging message carries a TAI list and a MAI list.

S411: The base station pages the UE according to the TAI list.

S412: The base station sends a paging message to the transmission point of the NR network according to the MAI list.

S413: The transmission point of the NR network pages the UE on the air interface.

In the process of the subsequent S410 to S413, as in the foregoing embodiment, in this step, when the UE has a service, the core network device pages the UE according to the TAI list and the MAI list previously configured for the UE. Sending a paging message to the corresponding eNB, where the paging message carries a TAI list and a MAI list configured by the core network device for the UE. The eNB receives the paging message sent by the core network device, and the paging message has a TAI list. When the eNB finds that the TAI list contains its own TAI, it initiates paging to the UE on the corresponding LTE cell. The eNB decides whether to forward the paging message to the transmission point of the NR network with which the interface exists, according to the MAI list in the paging message received from the core network device. The paging message forwarded at this time may only carry the MAI list without carrying the TAI list, or may not carry the TAI list and the MAI list. After receiving the paging message sent by the eNB, the transmission point of the NR network pages the UE on the corresponding NR cell.

In the paging method provided in this embodiment, the NR capability indication information is not required to be added to the attach request message when the UE first attaches. In the subsequent interaction process, the UE reports the NR capability indication information to the base station, and based on this, the core network device is the UE. The TAI list and the MAI list are configured at the same time to reduce the signaling load of the core network device. The eNB forwards the paging message to the transmission point of the corresponding NR network according to the MAI list configured by the core network device for the UE, so as to implement paging of the NR UE under the transmission point of the NR network. It is ensured that the NR UE can also be paged on the NR cell, and only the NR UE is paging in the NR cell, which reduces the paging load on the NR cell, provides the paging success rate of the NR UE, and realizes the non-independent deployment. Paging optimization in the NR network system.

In the foregoing embodiments, after obtaining the NR capability indication information of the UE, the core network device configures the TAI list and the MAI list for the UE at the same time, that is, the UE is paged on the LTE cell and the NR cell by default. There is a possibility that the UE may be stationary and the mobility is very low, so that the TAI list and the MAI list are not configured for the UE at the beginning, which causes a waste of paging resources. Therefore, an alternative is proposed. The UE is an NR UE. When the UE moves in the LTE cell corresponding to the TAI list configured by the core network device, the UE does not interact with the core network device. For the service, the core network device will page the UE on the corresponding LTE cell according to the TAI list. At this time, the paging load on the NR cell is further reduced as compared with the foregoing embodiment. When the NR UE moves from the LTE cell to the NR cell, the MAI of the NR cell does not belong to the TAI list configured by the core network device for the UE in the previous attach procedure, so the UE initiates a mobile area update procedure. The UE sends a mobile area update message to the transmission point of the NR network, and then forwards to the eNB, and finally reaches the core network device. The core network device can know the UE before An attach request is initiated in the LTE cell, and a TAI list is configured for the UE, and the core network device can know that the UE initiates a mobile area update request message in the NR cell, so the core network device is the UE. The MAI list is configured to indicate that the UE does not need to interact with the core network device when moving on the corresponding LTE cell and the NR cell.

At this time, the mobile area update accept message may include a TAI list and a MAI list; and may also be a MAI list and an indication for notifying the UE to simultaneously retain the MAI list and the previously configured TAI list. The mobile area update accept message is sent by the core network device to the eNB, and then forwarded by the eNB to the transmission point of the NR network, and finally sent to the UE. The core network device does not directly configure the TAI list and the MAI list for the UE, which further reduces the paging load on the NR cell.

On the other hand, if the UE moves in the NR cell corresponding to the MAI list configured by the core network device, the UE does not interact with the core network device. If there is a service, the core network device according to the MAI list. Paging the UE on the corresponding NR cell. Specifically, the core network device sends a paging message to the corresponding eNB according to the MAI information received from the eNB when the S1 interface is established, where the paging message carries The MAI list, after receiving the paging message with the MAI list, the eNB forwards the paging message to the transmission point of the corresponding NR network, and finally, the transmission point of the NR network that receives the paging message is in the corresponding The NR network capable UE is paged on the NR cell. At this time, compared with the foregoing embodiment, the NR UE is only paged at the transmission point of the NR network, which reduces the paging load on the LTE cell. When the UE moves from the NR cell to the LTE cell, the TAI of the LTE cell does not belong to the MAI list configured by the NR UE before the core network device, and the UE initiates the TAU. The initiating TAU process is the same as the existing LTE technology, and the UE sends a TAU request message to the eNB, and the eNB forwards the TAU request message to the core network device. The core network device replies to the TAU accept message, and the core network device can know that the UE previously initiated the attach request in the NR cell, and configures the MAI list for the UE, and the core network device can know that the UE is in the LTE at this time. The cell initiates a TAU request message, so the core network device configures the TAI list for the UE, and indicates that the UE does not need to interact with the core network device when moving on the corresponding LTE cell and the NR cell.

At this time, the TAU accept message may include a TAI list and a MAI list; or may be a TAI list and an indication, the indication is used to notify the UE to simultaneously reserve the TAI list and the previously configured MAI list, the TAU accept message by the core The network device sends the eNB to the eNB, and then the eNB sends the UE to the UE, and then the UE is subsequently paged. The core network equipment in this scheme is not directly for the UE. When the TAI list and the MAI list are configured, the paging load on the LTE cell is reduced.

In any of the foregoing implementation manners, the S1 interface needs to be established between the base station and the core network device, and the manner of establishing the S1 interface may be implemented as follows: the base station acquires the transmission of the NR network that has an interface with the base station. And the base station sends an S1 interface setup request message to the core network device, where the S1 interface setup request message includes an interface with the base station. The cell identifier of all NR cells managed by the transmission point of the NR network and the MAI corresponding to each NR cell may also be all the MAIs under the transmission point of the NR network and the NR cell identifier corresponding to each MAI; the core network device receives After the S1 interface establishes the request message, the corresponding configuration is performed, and the S1 interface setup response message is returned to the base station, and the base station receives the S1 interface setup response message returned by the core network device, and completes the establishment process of the S1 interface.

In this solution, the correspondence between the MAI and the NR cell identifier includes at least the following two modes:

Table 1

In Table 1, the NR cells whose MAI is A are: NR cell 1 and NR cell 2; and the NR cell whose MAI is B has NR cell 3.

Table 2

NR小区标识NR cell identification	MAIMAI
11	AA
22	AA
33	BB

Table 2 shows that the MAI of NR cell 1 and NR cell 2 is A, and the MAI of cell 3 is B.

In a specific implementation, the relationship between the NR cell and the MAI may be corresponding to any one of the foregoing manners, and the solution is not limited.

In the above embodiments 1 to 4. And in the alternative, the present invention also provides some improvements for the process of initial attachment of the UE. The following describes the attachment process of the UE separately:

FIG. 7 is a schematic diagram of a signaling interaction process according to Embodiment 1 of the method for attaching the present invention. As shown in FIG. 7 , as in the foregoing paging method, an S1 interface needs to be established between the eNB and the core network device before attaching, in the NR network. The configuration of the X5 interface is established between the transmission point and the eNB. The manner of establishing the specific S1 interface and the X5 interface is the same as that of the foregoing embodiment, and details are not described herein. The specific implementation steps of the attachment method are:

S501: The UE sends an attach request message to a transmission point of the NR network.

S502: The transmission point of the NR network sends the attach request message to the base station.

S503: The base station adds the NR capability indication information of the UE to the attach request message, and sends an attach request message after the NR capability indication information is added to the core network device.

In this step, after receiving the attach request message forwarded by the transmission point of the NR network, the eNB adds an NR capability indication information to the attach request message, and sends the NR capability indication information to the core network device. The NR capability indication information is used to notify the core network device that the attach request message is from an air interface of the NR network, that is, the UE that sends the attach request message has an NR network capability.

S504: The core network device configures a TAI list and a MAI list for the UE according to the NR capability indication information.

In this step, after receiving the attach request message, the core network device learns that the UE is an NR UE by using the NR capability indication information in the attach request message, and simultaneously configures the TAI list and the MAI list for the UE. The attach accept message is sent to the eNB. The MAI list contains at least one MAI. The core network device configures the TAI list and the MAI list for the NR network-capable UE at the same time, mainly considering that there is overlapping coverage between the NR cell and the LTE cell, and the LTE cell can ensure continuous coverage, and the NR cell may be in a point-like deployment. Guarantee continuous coverage. At this time, the idle state UE may enter the LTE cell from one NR cell during the mobile process, and then re-enter the NR cell. If the core network device only configures the MAI list at this time, when the UE enters the LTE cell, it triggers the TAU on the LTE cell, and when it enters the NR cell, it triggers the MAU on the NR cell, in the LTE cell and the NR cell. Frequent movement between the core network equipment signaling The load increased. Considering that both the LTE cell and the NR cell are managed by the core network device (for example, the MME of the LTE network), in order to reduce the signaling load, when the UE is determined to be the NR UE, the TAI list and the MAI can be simultaneously configured for the UE. List. In this way, the NR UE can move within the LTE cell and the NR cell corresponding to the TAI list and the MAI list without interacting with the core network device.

S505: The core network device sends an attach accept message carrying the TAI list and the MAI list to the base station.

In this step, the core network device carries the configured TAI list and the MAI list in the attach and receive message to the eNB.

S506: The base station forwards the attach accept message carrying the TAI list and the MAI list to the transmission point of the NR network.

In this step, the eNB sends an attach accept message received from the core network device to the transmission point of the corresponding NR network, where the attach accept message carries the TAI list and the MAI list configured by the MME for the NR UE.

S507: The transmission point of the NR network forwards the attach accept message carrying the TAI list and the MAI list to the UE.

In this step, the transmission point of the NR network receives the attach accept message of the core network device replies to the UE from the eNB, and forwards the message to the UE, where the attach accept message carries the TAI list configured by the core network device for the UE. And the MAI list, complete the attachment process of the UE.

Based on the attaching process, the UE may directly send an attach request message to the base station, where the attach request message carries the NR capability indication information of the UE, and the subsequent attach process is the same as the embodiment.

Optionally, in this embodiment, the core network device may configure the MAI list only for the UE in the process of attaching the UE, and the specific implementation process may refer to the attach process in the second embodiment of the paging method.

In the attaching method provided in this embodiment, by adding the NR capability indication information of the UE to the attach request message sent to the core network device, the core network device can simultaneously configure the MAI list and the TAI list for the UE, thereby effectively saving the signaling of the core network device. The overhead is increased, and when the subsequent UE has downlink traffic, the paging success rate for the UE is increased.

In any of the foregoing embodiments, the core network device configures the TAI list regardless of the NR capability indication information in the attaching process or the paging process, but uses the existing configuration method of the tracking area of the LTE network.

In any of the above embodiments, when the NR network is deployed based on the LTE network, the core network device generally refers to the MME, and may also be a P-GW or an S-GW. The solution is not limited to the foregoing device.
