Description

Paging method, base station, core network equipment and user equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a paging method, a base station, a core network device, and a user equipment.

Background

The goal of Machine To Machine (M2M) communication technology is To enable all Machine devices with networking and communication capabilities. The M2M technology has very important significance and has wide market and application prospects. The wireless communication module is embedded in the machine, so that the machine can be monitored, commanded and scheduled, and data acquisition, measurement and the like. Therefore, the M2M technology can be applied to different schemes, such as an intelligent meter reading system, environmental monitoring, remote monitoring and the like.

Since many M2M devices such as sensors, meters, etc. may be deployed in corners or in basement areas with poor coverage, the coverage of the M2M network is better than that of current cellular networks and the coverage enhancement is 20dB in order to make these devices in the poor coverage areas successfully use the M2M network. In order to meet the requirement of increasing coverage by 20dB, the M2M system designs 3 coverage levels, and different Modulation and Coding Schemes (MCS) can be selected for different coverage levels, where the MCS includes a Modulation scheme, a code rate, a spreading factor, and a repetition number. Higher coverage levels indicate poorer coverage, higher spreading factors and repetition times are required.

Currently there are two versions of User Equipment (UE): the UE of the first release can only page the UE at the worst coverage level, and paging messages of UEs with different coverage conditions are mapped to the same resource, i.e. an evolved Node B (base station) can only page the UE at the worst coverage level; the second release UE can receive paging at different coverage levels, and paging messages of the UE with different coverage conditions can be mapped to resources with different coverage levels for transmission.

The existing paging method can not be simultaneously and effectively applied to paging of UE of different versions, thereby causing low utilization rate of system resources and large power consumption of the UE.

Detailed Description

Based on the defects in the prior art, embodiments of the present invention provide a paging method, a base station, and a core network device, which aim to solve the technical problem of how to adopt different paging schemes for UEs of different versions, thereby effectively saving UE power consumption and improving system resource utilization.

The technical scheme of the invention is explained in detail in the following by combining the drawings and specific embodiments:

referring to fig. 1, fig. 1 is a flowchart of a paging method according to an embodiment of the present invention, which is described in the context of a base station in the present embodiment, and as shown in the drawing, the paging method according to the present embodiment includes:

s101: the base station informs the user equipment UE of the version information of the core network equipment;

the base station may be connected to the second-version core network device or the first-version core network device, and before performing communication, the base station first notifies the UE of the version information of the core network device connected to the base station, so that the UE knows the core network information connected to the base station. The second version core network equipment in the embodiment of the invention refers to modified core network equipment, and can store UE coverage grade information or call new version core network equipment; the first edition core network equipment is traditional core network equipment, cannot store UE coverage grade information, and can also be called old edition core network equipment.

The base station may notify the UE of the version information of the core network device connected to the base station in the form of a system message.

S102: when the core network equipment is the second edition core network equipment, the base station acquires the coverage grade of the UE;

among them, the Coverage grades of the M2M system are Coverage grade 0(Coverage Class0, CC0) indicating normal Coverage, and Coverage grade 1(Coverage Class1, CC1) and Coverage grade 2(Coverage Class2, CC2) are called Coverage enhancement scenarios.

When the core network device of the second version is connected with the base station, the UE reports its coverage level information to the base station, wherein the UE may notify the base station of its coverage level information through a Random Access Channel (RACH) message indication. Or reporting the coverage grade of the base station to the base station through the resource occupied by the RACH message. Because the frequency resources utilized by the UEs with different coverage levels to send the random access request are different, the base station can identify the coverage level accordingly.

The old version UE mentioned in the embodiment of the invention refers to the UE which can only receive paging at the worst coverage level and can also be called the first version UE; the new release UE refers to a UE that can receive paging at different coverage levels, and may also be called a second release UE. For the UE with new version, the UE selects the coverage grade of the UE when initially accessing the network, then the UE can autonomously change the coverage grade and tell the base station through the RACH message or the resource occupied by the RACH message, so that the base station can update the coverage grade of the UE in real time.

S103: informing the coverage grade of the core network equipment UE;

and the base station informs the coverage level of the core network equipment UE through an interface message between the base station and the core network.

In specific implementation, the embodiments of the present invention may be directed to core networks of different architectures, for example, when the core network is a Long Term Evolution (LTE) architecture core network, a core network device in the embodiments of the present invention is a mobility management entity MME, and a base station notifies an MME of a coverage level of a user equipment through an S1 interface signaling. The addition of the information element in the "UE CONTEXT RELEASE COMPLETE message" indicates the coverage level of the UE, e.g., by means of an S1 signaling message. Or when the core network is a Global System for Mobile Communication (GSM) core network, the core network device in the embodiment of the present invention is a Serving GPRS Support Node (SGSN), and the base station notifies the coverage level of the SGSN user equipment through a Gb interface message. For example, the base station informs the SGSN of the coverage level of the user equipment via "UL-UNITDATA PDU".

In the embodiment of the present invention, two possible implementation manners may be available for notifying the core network device of the coverage level of the UE: one is that the base station acquires version information of the UE, determines a coverage level for paging the UE according to the version information of the UE, and then directly notifies the core network device of the coverage level for paging the UE, so that the core network device stores the coverage level for paging the UE. The other method is that the base station informs the core network equipment of the coverage grade of the UE regardless of the version of the UE, and the core network equipment determines the coverage grade for paging the UE according to the version information of the UE and stores the coverage grade.

Wherein, when the coverage level for paging the UE is determined by the base station, the base station may acquire version information of the UE from a control element (MAC CE) of media access control from the UE or from a random access request message from the UE. For example, the UE carries 1bit indication information in the random access request message to indicate the UE version, for example, "1" indicates a new version, and "0" indicates an old version. Or the UE adds a MAC CE to indicate UE capability related information, including UE version information.

The coverage level for paging the UE mentioned in the embodiment of the present invention is a coverage level at which the UE can receive paging. That is, for example, for an old version UE that can only receive paging at the worst coverage level, the coverage level used for paging the UE refers to the worst coverage level, and for a new version UE that can receive paging at a different coverage level, the coverage level used for paging the UE is the coverage level at which the UE is currently located.

Wherein, the base station determining the coverage grade for paging the UE according to the version information of the UE comprises:

and if the UE is the old version UE, determining the coverage grade for paging the UE as the worst coverage grade, and if the UE is the new version UE, determining the coverage grade for paging the UE as the coverage grade of the UE.

Of course, the base station may also directly notify the core network device of the coverage level reported by the UE without processing, and the core network device determines the coverage level for paging the UE according to the version information of the UE and stores the coverage level.

When the core network device determines the coverage level for paging the UE, the core network device may obtain version information of the UE from a non-access stratum NAS message from the UE, obtain the coverage level of the UE from an interface message between the base station and the core network, and determine the coverage level for paging the UE according to the version information of the UE.

The method for determining the coverage level for paging the UE by the core network equipment according to the version information of the UE comprises the following steps:

and if the UE is the old-version UE, determining the coverage grade for paging the UE to be the worst coverage grade no matter what the coverage grade of the UE is notified by the base station, and if the UE is the new-version UE, determining the coverage grade for paging the UE to be the coverage grade where the UE is located.

S104: receiving a paging message from core network equipment, wherein the paging message carries a coverage grade stored by the core network equipment and used for paging UE;

the paging message is used for instructing the base station to page the UE on a channel corresponding to the coverage grade used for paging the UE.

The core network equipment pages the UE, and sends a PAGING (PAGING) message to the base station through an interface between the base station and the core network at a PAGING occasion to initiate a PAGING process, wherein the PAGING message carries a coverage grade for PAGING the UE. The coverage grade of the UE carried in the paging message is the coverage grade stored in the core network device for paging the UE. That is, if the paging is the old version UE, the paging message carries the worst coverage class, and if the paging is the new version UE, the paging message carries the coverage class of the UE currently stored in the core network device.

And the base station receives the paging message from the core network equipment and acquires the coverage level for paging the UE from the paging message.

S105: and paging the UE on a channel corresponding to the coverage grade for paging the UE.

And the base station pages the UE on a channel corresponding to the coverage grade for paging the UE.

In the above paging process, when the core network device is a second-version core network device, and when the base station learns that the UE is an old-version UE, the base station may not notify the version information of the core network device UE and the coverage level of the UE, and the core network device does not store the version information of the old-version UE and the coverage level of the UE. And when the paging message carries the coverage grade, the base station pages the UE on a channel corresponding to the carried coverage grade by default.

In this embodiment, when the core network device is a first-version core network device, the UE can only be paged according to a conventional paging method. That is, the core network device sends a PAGING message to the base station through the interface between the base station and the core network to initiate a PAGING procedure, because the first version core network device does not have the capability of storing the coverage level of the UE, the PAGING message does not carry the coverage level of the UE. And the base station receives the paging message from the first edition core network equipment and pages the UE on the worst coverage level uniformly. That is, when the first-version core network device is connected to the base station, the paging message can be received only at the worst coverage level regardless of the new-version UE or the old-version UE.

In the paging method provided in the above embodiment of the present invention, when the base station is connected to the second version core network device, the coverage class of the UE is obtained, and the coverage class of the UE is notified to the core network device, the core network device stores the coverage class used for paging the UE, and when paging is performed, the base station receives a paging message from the core network device, where the paging message carries the coverage class used for paging the UE, and the base station pages the UE on a channel corresponding to the coverage class used for paging the UE. The core network equipment stores the coverage grade of the UE currently located aiming at the UE of the new version, stores the worst coverage grade aiming at the UE of the old version, and carries the coverage grade of the UE stored by the core network equipment in the paging message for initiating paging, so that different paging schemes can be adopted aiming at the UE of different versions, the power consumption of the UE can be saved, and the utilization rate of system resources can be improved.

Referring to fig. 2, fig. 2 is a flowchart of another paging method according to an embodiment of the present invention, which is described in the context of a core network device in the present embodiment, and as shown in the drawing, the paging method according to the present embodiment includes:

s201: when the core network equipment is second-version core network equipment, the core network equipment acquires and stores a coverage level for paging User Equipment (UE);

the base station may be connected to the second-version core network device or the first-version core network device, and before performing communication, the base station first notifies the UE of the version information of the core network device connected to the base station, so that the UE knows the core network information connected to the base station. The second version core network equipment mentioned in the embodiment of the invention is modified core network equipment and can store UE coverage grade information or be called new version core network equipment; the first-version core network device is a traditional core network device, cannot store UE coverage level information, and may also be called an old-version core network device.

And when the second version core network equipment is connected with the base station, the UE reports the coverage grade information of the UE to the base station, wherein the UE can inform the base station of the coverage grade information of the UE through RACH message indication. Or reporting the coverage grade of the base station to the base station through the resource occupied by the RACH message.

The old version UE mentioned in the embodiment of the invention refers to the UE which can only receive paging at the worst coverage level and can also be called the first version UE; the new release UE refers to a UE that can receive paging at different coverage levels, and may also be called a second release UE. For the UE with the new version, the UE selects the coverage grade of the UE when initially accessing the network, the UE is informed to the base station through the RACH in the access process, then the UE can change the coverage grade autonomously, and the base station is informed through the coverage grade carried in the RACH message, so that the base station can update the coverage grade of the UE in real time.

In specific implementation, the embodiment of the present invention may be directed to core networks of different architectures, for example, when the core network is an LTE architecture core network, the core network device in the embodiment of the present invention is a mobility management entity MME, and the base station notifies, through an S1 interface, the coverage level of the MME user equipment. The addition of the information element in the "UE CONTEXT RELEASE complete message" indicates the coverage level of the UE, e.g., by means of an S1 signaling message. Or when the core network is a GSM core network, the core network device of the embodiment of the present invention is an SGSN, and the base station notifies the coverage level of the SGSN user device through a Gb interface message. For example, the base station informs the SGSN of the coverage level of the user equipment via "UL-UNITDATA PDU".

In the embodiment of the present invention, there are two possible implementation manners for the core network device to acquire and store the coverage level for paging the UE: one is that the base station obtains the version information of the UE, and after determining the coverage level for paging the UE according to the version information of the UE, the base station directly informs the core network equipment of the user of the coverage level for paging the UE through the interface message between the base station and the core network, so that the core network equipment stores the coverage level for paging the UE. The other method is that the base station informs the core network equipment of the coverage grade of the UE through an interface message between the base station and the core network regardless of the version of the UE, and the core network equipment determines the coverage grade for paging the UE according to the version information of the UE and stores the coverage grade.

Wherein, when the coverage level for paging the UE is determined by the base station, the base station may acquire the version information of the UE from a MAC CE of media access control from the UE or from a RACH message from the UE. For example, the UE carries 1bit indication information in the RACH message to indicate the UE version, for example, "1" indicates a new version, and "0" indicates an old version. Or the UE adds a mac ce to indicate the UE capability related information, including the UE release.

When the core network device determines the coverage level for paging the UE, the core network device may obtain version information of the UE from a non-access stratum NAS message from the UE, obtain the coverage level of the UE from an interface message between a base station and the core network from the base station, and determine the coverage level for paging the UE according to the version information of the UE.

S202: the core network equipment sends a paging message to the base station, and the paging message carries the coverage grade which is stored by the core network equipment and is used for paging the UE, so that the base station pages the UE on a channel corresponding to the coverage grade used for paging the UE.

When the UE needs to be paged, the core network device sends a PAGING message to the base station through an interface between the base station and the core network to initiate PAGING, and carries a coverage class for PAGING the UE in the PAGING message, where the coverage class for PAGING the UE carried in the PAGING message is a coverage class of the UE stored in the core network device. That is, if the paging is the old version UE, the paging message carries the worst coverage class, and if the paging is the new version UE, the paging message carries the coverage class of the UE currently stored in the core network device. So that the base station pages the UE on the channel corresponding to the coverage level used to page the UE.

And the base station receives the paging message from the core network equipment, acquires the coverage grade for paging the UE from the paging message, and pages the UE on a channel corresponding to the coverage grade for paging the UE.

In the above paging process, when the base station learns that the UE is an old version UE, the base station may not notify the coverage level of the core network device UE, the second version core network device does not store the coverage level of the old version UE, and when paging is initiated, the paging message does not carry the coverage level for the old version UE, and the paging message carries the coverage level of the UE currently stored in the core network device for the new version UE. And when the paging message carries the coverage grade, the base station pages the UE on a channel corresponding to the carried coverage grade by default.

In the paging method provided in the above embodiment of the present invention, when the base station is connected to the second version core network device, the base station acquires the coverage level of the UE, and notifies the core network device of the coverage level of the UE, so that the core network device stores the coverage level for paging the UE. The core network equipment stores the coverage grade of the UE currently located aiming at the UE of the new version, stores the worst coverage grade aiming at the UE of the old version, and carries the coverage grade of the UE stored by the core network equipment in the paging message for initiating paging, so that different paging schemes can be adopted aiming at the UE of different versions, the power consumption of the UE can be saved, and the utilization rate of system resources can be improved.

As another implementation, the second-version core network device may only store coverage level information of a new-version UE, and not store coverage level information of an old-version UE, and when paging is performed, the coverage level is not carried for the old-version UE, and the coverage level of the UE currently stored in the core network device is carried for the new-version UE, so that the base station pages the UE on a channel of a coverage level carried when the coverage level is carried in the paging message, and when the coverage level is not carried in the paging message, the UE is paged on a channel of the worst coverage level by default. Therefore, the storage space of the core network equipment can be saved, different paging schemes can be adopted for different versions of UE, the energy consumption of the UE is saved, and the utilization rate of system resources is improved.

Referring to fig. 3, fig. 3 is a flowchart of another paging method according to an embodiment of the present invention, where the paging method of the embodiment is described in terms of a user equipment UE, as shown in the figure, the paging method of the embodiment includes:

s301: user Equipment (UE) acquires version information of core network equipment;

the base station may be connected to the second-version core network device or the first-version core network device, and before performing communication, the base station first notifies the UE of the version information of the core network device connected to the base station, so that the UE knows the core network information connected to the base station. The second version core network equipment mentioned in the embodiment of the invention is modified core network equipment, can store UE coverage grade information, or can be called new version core network equipment; the first edition core network equipment is traditional core network equipment, cannot store UE coverage grade information, and can also be called old edition core network equipment.

The UE may obtain version information of a core network device connected to the base station from a system message from the base station.

S302: the UE determines that the core network equipment is the second version of core network equipment according to the version information;

the UE determines that the core network device connected to the base station is the core network device of the second version according to the version information of the core network device connected to the base station, and executes step S303.

S303: the UE reports the coverage grade of the UE to the base station, and the UE reports the version information of the UE to the base station or core network equipment;

the version information of the UE is used for the base station or the core network equipment to determine the coverage grade for paging the UE according to the version information of the UE, and the core network equipment stores the coverage grade for paging the UE.

The base station may notify the coverage level of the UE to the core network device through an interface message between the base station and the core network.

In the embodiment of the present invention, two possible implementation manners may be available for notifying the core network device of the coverage level of the UE: one is that the base station acquires version information of the UE, and directly informs the core network equipment of the user of the coverage level for paging the UE after determining the coverage level for paging the UE according to the version information of the UE, so that the core network equipment stores the coverage level for paging the UE. The other method is that the base station informs the core network equipment of the coverage grade of the UE regardless of the version of the UE, and the core network equipment determines the coverage grade for paging the UE according to the version information of the UE and stores the coverage grade.

Wherein, when the coverage level for paging the UE is determined by the base station, the base station may acquire the version information of the UE from a control element (MAC CE) of media access control from the UE or from a RACH message from the UE. For example, the UE carries 1bit indication information in the RACH message to indicate the UE version, for example, "1" indicates a new version, and "0" indicates an old version. Or the UE adds a MAC CE to indicate the UE capability related information, including the UE version.

S304: the UE receives a page on a channel corresponding to a coverage level used to page the UE.

When the UE needs to be paged, the core network device sends a PAGING message to the base station through an interface between the base station and the core network to initiate PAGING, and carries a coverage class for PAGING the UE in the PAGING message, where the coverage class for PAGING the UE carried in the PAGING message is a coverage class of the UE stored in the core network device. That is, if the paging is the old version UE, the paging message carries the worst coverage class, and if the paging is the new version UE, the paging message carries the coverage class of the UE currently stored in the core network device, so that the base station pages the UE on the channel corresponding to the coverage class used for paging the UE.

The UE receiving the page on a channel of a coverage class used to page the UE includes: and if the UE is the old version UE, receiving paging on the channel corresponding to the worst coverage grade, and if the UE is the new version UE, receiving paging on the channel corresponding to the coverage grade where the UE is located.

In the paging process, when the base station learns that the UE is the old version UE, the base station may not notify the coverage level of the core network device UE, the second version core network device does not store the coverage level of the old version UE, and when paging is initiated, the base station does not carry the coverage level in the paging message for the old version UE and carries the coverage level of the UE currently stored in the core network device for the new version UE. And when the paging message carries the coverage grade, the base station pages the UE on a channel corresponding to the carried coverage grade by default. The new-version UE receives paging on a channel corresponding to the coverage level of the new-version UE, and the old-version UE receives paging on the worst coverage level.

In this embodiment, when the UE determines that the core network device is the first-version core network device according to the version information, the UE does not perform the action of reporting the version information and the coverage level of the UE, and the core network device does not store the coverage level information of the UE and can only page the UE according to the conventional paging method. That is, the core network device sends a PAGING message to the base station through the interface between the base station and the core network to initiate a PAGING procedure, because the first version core network device does not have the capability of storing the coverage level of the UE, the PAGING message does not carry the coverage level of the UE. And the base station receives the paging message from the first edition core network equipment and pages the UE on the worst coverage level uniformly. That is, when the first release core network device is connected to the base station, the paging message is received at the worst coverage level regardless of the new release UE or the old release UE.

In the paging method of the embodiment of the present invention, when the base station is connected to the second-version core network device, the UE reports the version information and the coverage level of the UE, so that the core network device stores the coverage level for paging the UE, and the UE receives the paging message on the channel of the coverage level for paging the UE. For old-version UE, the core network equipment stores the worst coverage grade, for new-version UE, the core network equipment stores the coverage grade of the current UE, and during paging, the core network equipment carries the coverage grade of the UE stored by the core network equipment, and the UE receives paging on a channel corresponding to the coverage grade. By the mode, different paging schemes can be adopted for the UE of different versions, the power consumption of the UE can be saved, and the utilization rate of system resources can be improved.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a base station according to an embodiment of the present invention, where the base station of this embodiment is configured to perform the paging method according to the embodiment shown in fig. 1, as shown, the base station 100 of this embodiment includes a first notification module 11, an obtaining module 12, a second notification module 13, a receiving module 14, and a paging module 15, where:

the first notification module 11 is configured to notify the user equipment UE of version information of the core network device;

the base station may be connected to the second-version core network device or the first-version core network device, and before performing communication, the first notification module 11 first notifies the UE of the version information of the core network device connected to the UE, so that the UE knows the core network information connected to the base station. The second version core network equipment in the embodiment of the invention refers to modified core network equipment, and can store UE coverage grade information or call new version core network equipment; the first edition core network equipment is traditional core network equipment, cannot store UE coverage grade information, and can also be called old edition core network equipment.

The first notification module 11 may notify the UE of the version information of the core network device connected thereto in the form of a system message.

The obtaining module 12 is configured to obtain the coverage level of the UE when the core network device is a second-version core network device, where the second-version core network device is a modified core network device and is capable of storing the coverage level of the UE or is a new-version core network device;

and when the second version core network equipment is connected with the base station, the UE reports the coverage grade information of the UE to the base station, wherein the UE can inform the base station of the coverage grade information of the UE through RACH message indication. Or reporting the coverage grade of the base station to the base station through the resource occupied by the RACH message. The acquisition module 12 determines the coverage level of the UE from the RACH message from the UE or the resource occupied by the RACH message.

The second notification module 13 is configured to notify the coverage level of the UE to the core network device according to the coverage level of the UE acquired by the acquisition module 12;

the second notification module 13 notifies the coverage level of the core network device UE through an interface message between the base station and the core network.

Please refer to fig. 5 further, where fig. 5 is a schematic structural diagram of another base station provided in an embodiment of the present invention when the base station determines the coverage level for paging the UE, where the base station in this embodiment is used to execute the paging method in the embodiment shown in fig. 1, and on the basis of the embodiment shown in fig. 4, the base station in the embodiment shown in fig. 5 further includes a determining module 16, and specific functional implementation of the remaining working modules is the same as that shown in fig. 4, and is not described again here. In the embodiment shown in fig. 5, the obtaining module 12 may obtain the version information of the UE from the MAC CE of the medium access control of the UE or from the RACH message from the UE. For example, the UE carries 1bit indication information in the RACH message to indicate the UE version, for example, "1" indicates a new version, and "0" indicates an old version. Or the UE adds a MAC CE to indicate UE capability related information, including UE version information. The determining module 16 is configured to determine a coverage level for paging the UE according to the version information of the UE, and output the coverage level to the second notifying module 13.

Wherein, the determining module 16 determines the coverage level for paging the UE according to the version information of the UE includes:

Of course, the base station may also directly notify the core network device of the coverage level reported by the UE without processing, and the core network device determines and stores the coverage level for paging the UE according to the version information of the UE.

The receiving module 14 is configured to receive a paging message from a core network device, where the paging message carries a coverage level for paging a UE, the coverage level for paging the UE is a coverage level at which the UE can receive paging, and the paging message is used to instruct a base station to page the UE on a channel corresponding to the coverage level for paging the UE;

The receiving module 14 receives a paging message from the core network device, and obtains a coverage level for paging the UE from the paging message.

The paging module 15 is configured to page the UE on a channel corresponding to a coverage class for paging the UE according to the paging message received by the receiving module 14.

The paging module 15 pages the UE on a channel corresponding to a coverage class used for paging the UE according to the paging message received by the receiving module 14.

In the above paging process, when the core network device is a second-version core network device, and when the base station learns that the UE is an old-version UE, the base station may not notify the version information of the core network device UE and the coverage level of the UE, and the core network device does not store the version information of the old-version UE and the coverage level of the UE. When the receiving module 14 receives a paging message not carrying a coverage class, the paging module 15 defaults to page the UE on the worst coverage class, and when the paging message carries a coverage class, the paging module 15 pages the UE on a channel corresponding to the carried coverage class.

In this embodiment, when the core network device is a first-version core network device, the UE can only be paged according to a conventional paging method. That is, the core network device sends a PAGING message to the base station through the interface between the base station and the core network to initiate a PAGING procedure, because the first version core network device does not have the capability of storing the coverage level of the UE, the PAGING message does not carry the coverage level of the UE. The receiving module 14 receives the paging message from the first release core network device, and the paging module 15 pages the UE on the worst coverage level according to the paging message received by the receiving module 14. That is, when the first-version core network device is connected to the base station, the paging message can be received only at the worst coverage level regardless of the new-version UE or the old-version UE.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a core network device according to an embodiment of the present invention, where the core network device is configured to execute the paging method according to the embodiment shown in fig. 2, as shown, a core network device 200 according to the present embodiment includes an obtaining module 21, a storing module 22, and a paging module 23, where:

the obtaining module 21 is configured to, when the core network device is a second-version core network device, obtain a coverage level for paging the UE, where the coverage level for paging the UE is a coverage level at which the UE can receive paging, and the second-version core network device is a modified core network device, and is capable of storing the coverage level of the UE, or is a new-version core network device;

Wherein, when the coverage level for paging the UE is determined by the base station, the base station may acquire version information of the UE from a MAC CE of media access control from the UE or from a random access request message from the UE. For example, the UE carries 1bit indication information in the random access request message to indicate the UE version, for example, "1" indicates a new version, and "0" indicates an old version. Or the UE adds a MAC CE to indicate the UE capability related information, including the UE version.

When the core network device determines the coverage level for paging the UE, the obtaining module 21 may obtain version information of the UE from a non-access stratum NAS message from the UE, obtain the coverage level of the UE from an interface message between a base station and the core network from the base station, and determine the coverage level for paging the UE according to the version information of the UE.

The storage module 22 is configured to store the coverage level for paging the UE acquired by the acquisition module 21;

the paging module 23 is configured to send a paging message to the base station, where the paging message carries a coverage class stored by the core network device and used for paging the UE, and the paging message is used to instruct the base station to page the UE on a channel corresponding to the coverage class used for paging the UE.

When the UE needs to be paged, the PAGING module 23 sends a PAGING message to the base station through an interface between the base station and the core network to initiate PAGING, and carries a coverage class for PAGING the UE in the PAGING message, where the coverage class for PAGING the UE carried in the PAGING message is a coverage class of the UE stored in the core network device. That is, if the paging is the old version UE, the paging message carries the worst coverage class, and if the paging is the new version UE, the paging message carries the coverage class of the UE currently stored in the core network device. So that the base station pages the UE on the channel corresponding to the coverage level used to page the UE.

In the above paging process, when the base station learns that the UE is an old version UE, the base station may not notify the coverage level of the core network device UE, the second version core network device does not store the coverage level of the old version UE, when initiating paging, the paging module 23 does not carry the coverage level in the paging message for the old version UE, and the paging module 23 carries the coverage level of the UE currently stored in the core network device in the paging message for the new version UE. And when the paging message carries the coverage grade, the base station pages the UE on a channel corresponding to the carried coverage grade by default.

In this embodiment, when the core network device is a first-version core network device, the UE can only be paged according to a conventional paging method. That is, the PAGING module 23 sends a PAGING message to the base station through the interface between the base station and the core network to initiate a PAGING procedure, because the first version core network device does not have the capability of storing the coverage level of the UE, the PAGING message does not carry the coverage level of the UE. And the base station receives the paging message from the first edition core network equipment and pages the UE on the worst coverage level uniformly. That is, when the first-version core network device is connected to the base station, the paging message can be received only at the worst coverage level regardless of the new-version UE or the old-version UE.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a ue according to an embodiment of the present invention, where the ue according to the embodiment is configured to perform the paging method according to the embodiment shown in fig. 3. As shown in the figure, the ue 300 of this embodiment includes an obtaining module 31, a determining module 32, a reporting module 33, and a paging receiving module 34, where:

the obtaining module 31 is configured to obtain version information of a core network device;

The obtaining module 31 may obtain version information of a core network device connected to the base station from a system message from the base station.

The determining module 32 is configured to determine, according to the version information acquired by the acquiring module 31, that the core network device is a second version of core network device, where the second version of core network device is a modified core network device and is capable of storing a coverage level of the UE, or is a new version of core network device;

the determining module 32 determines that the core network device connected to the base station is the core network device of the second version according to the version information of the core network device connected to the base station, which is acquired by the acquiring module 31.

The reporting module 33 is configured to, when the determining module 32 determines that the core network device is the core network device of the second version, report the coverage level of the UE to the base station, and report version information of the UE to the base station or the core network device, where the version information of the UE is used by the base station or the core network device to determine the coverage level for paging the UE according to the version information of the UE, and the core network device stores the coverage level for paging the UE, where the coverage level for paging the UE is a coverage level at which the UE can receive paging;

When the core network device of the second version is connected to the base station, the reporting module 33 reports the coverage level information of the user equipment to the base station, wherein the reporting module 33 may notify the base station of the coverage level information by an RACH message indication. Or reporting the coverage grade of the base station to the base station through the resource occupied by the RACH message. Because the frequency resources utilized by the UEs with different coverage levels to send the random access request are different, the base station can identify the coverage level accordingly.

When the base station determines the coverage level for paging the UE, the reporting module 33 may report the version information of the UE to the base station through a media access control MAC CE or from an RACH message. For example, the RACH message carries 1bit indication information indicating the UE version, for example, "1" indicates a new version, and "0" indicates an old version. Or the UE adds a MAC CE to indicate the UE capability related information, including the UE version.

When the core network device determines the coverage level for paging the UE, the reporting module 33 may report the version information of the UE to the core network device through the NAS message, the core network device acquires the version information of the UE from the NAS message, acquires the coverage level of the UE from the interface message between the base station and the core network, and determines the coverage level for paging the UE according to the version information of the UE.

The paging receiving module 34 is configured to receive a page on a channel corresponding to a coverage class used for paging the UE.

The paging reception module 34 receiving the page on the channel of the coverage class for paging the UE includes: and if the UE is the old version UE, receiving paging on the channel corresponding to the worst coverage grade, and if the UE is the new version UE, receiving paging on the channel corresponding to the coverage grade where the UE is located.

In the paging process, when the base station learns that the UE is the old version UE, the base station may not notify the coverage level of the core network device UE, the second version core network device does not store the coverage level of the old version UE, and when paging is initiated, the base station does not carry the coverage level in the paging message for the old version UE and carries the coverage level of the UE currently stored in the core network device for the new version UE. And when the paging message carries the coverage grade, the base station pages the UE on a channel corresponding to the carried coverage grade by default. The paging receiving module 34 of the new-version UE receives the paging on the channel corresponding to its coverage level, and the paging receiving module 34 of the old-version UE receives the paging on the worst coverage level.

In this embodiment, when the determining module 32 determines that the core network device is the first-version core network device according to the version information, the reporting module 33 does not perform the action of reporting the version information and the coverage level of the UE, and the core network device does not store the coverage level information of the UE and can only page the UE according to the conventional paging method. That is, the core network device sends a PAGING message to the base station through the interface between the base station and the core network to initiate a PAGING procedure, because the first version core network device does not have the capability of storing the coverage level of the UE, the PAGING message does not carry the coverage level of the UE.

The bus system may be an ISA (Industry Standard Architecture) bus, a PCI (peripheral component Interconnect) bus, an EISA (Extended Industry Standard Architecture) bus, or the like. The bus may be one or more physical lines, and when a plurality of physical lines are provided, may be divided into an address bus, a data bus, a control bus, and the like.

the processor 41 is configured to control the transmitter 44 to transmit the version information of the core network device to the user equipment UE.

The base station may be connected to the second release core network device or the first release core network device, and before performing communication, the processor 41 controls the transmitter 44 to first notify the UE of the release information of the core network device connected to the UE, so that the UE knows the core network information connected to the base station. The second version core network equipment in the embodiment of the invention refers to modified core network equipment, and can store UE coverage grade information or call new version core network equipment; the first edition core network equipment is traditional core network equipment, cannot store UE coverage grade information, and can also be called old edition core network equipment.

Wherein the transmitter 44 may notify the UE of the version information of the core network device connected thereto in the form of a system message.

When the core network device is a second-version core network device, the processor 41 is configured to control the receiver 43 to receive the coverage level of the UE, where the second-version core network device is a modified core network device, and is capable of storing the coverage level of the UE, or is a new-version core network device.

And when the second version core network equipment is connected with the base station, the UE reports the coverage grade information of the UE to the base station, wherein the UE can inform the base station of the coverage grade information of the UE through RACH message indication. Or reporting the coverage grade of the base station to the base station through the resource occupied by the RACH message. The processor 41 controls the receiver 43 to determine the coverage level of the UE from the RACH message from said UE or the resource occupied by the RACH message.

The processor 41 is further configured to control the transmitter 44 to transmit the coverage level of the UE to the core network device.

Wherein the processor 41 may control the transmitter 44 to inform the core network device UE of the coverage level through a base station to core network interface message.

Wherein, when the coverage level for paging the UE is determined by the base station, the processor 41 controls the receiver 43 to acquire version information of the UE from a MAC CE of media access control from the UE or from a random access request message from the UE. For example, the UE carries 1bit indication information in the random access request message to indicate the UE version, for example, "1" indicates a new version, and "0" indicates an old version. Or the UE adds a MAC CE to indicate UE capability related information, including UE version information. The processor 41 determines a coverage level for paging the UE according to the version information of the UE.

Wherein, the determining, by the processor 41, the coverage level for paging the UE according to the version information of the UE includes:

The processor 41 controls the receiver 43 to receive a paging message from the core network device and to acquire a coverage level for paging the UE from the paging message.

Processor 41 controls paging of the UE on a channel corresponding to the coverage class used for paging the UE.

In the above paging process, when the core network device is a second-version core network device, and when the base station learns that the UE is an old-version UE, the base station may not notify the version information of the core network device UE and the coverage level of the UE, and the core network device does not store the version information of the old-version UE and the coverage level of the UE. When the receiver 43 receives a paging message not carrying a coverage class, the processor 41 defaults to paging the UE on the worst coverage class, and when the paging message carries a coverage class, the processor 41 pages the UE on a channel corresponding to the carried coverage class.

In this embodiment, when the core network device is a first-version core network device, the UE can only be paged according to a conventional paging method. That is, the core network device sends a PAGING message to the base station through the interface between the base station and the core network to initiate a PAGING procedure, because the first version core network device does not have the capability of storing the coverage level of the UE, the PAGING message does not carry the coverage level of the UE. The receiver 43 receives the paging message from the first release core network device, and the processor 41 pages the UE on the worst coverage level uniformly according to the paging message received by the receiver 43. That is, when the first-version core network device is connected to the base station, the paging message can be received only at the worst coverage level regardless of the new-version UE or the old-version UE.

And when the paging message carries the coverage grade, the base station pages the UE on a channel corresponding to the carried coverage grade by default.

Or reporting the coverage grade of the base station to the base station through the resource occupied by the RACH message. Because the frequency resources utilized by the UEs with different coverage levels to send the random access request are different, the base station can identify the coverage level accordingly.

Wherein, when the coverage level for paging the UE is determined by the base station, the transmitter 64 may report the version information of the UE to the base station through a MAC CE of media access control or from a RACH message. For example, the RACH message carries 1bit indication information indicating the UE version, for example, "1" indicates a new version, and "0" indicates an old version. Or the UE adds a MAC CE to indicate the UE capability related information, including the UE version.

And when the paging message carries the coverage grade, the base station pages the UE on a channel corresponding to the carried coverage grade by default. The processor 61 of the new release UE controls the paging to be received on the channel corresponding to its coverage level, and the processor 61 of the old release UE controls the paging to be received on the worst coverage level.

In this embodiment, when the processor 61 determines that the core network device is the first-version core network device according to the version information, the transmitter 64 does not perform the action of reporting the version information and the coverage level of the UE, and the core network device does not store the coverage level information of the UE and can only page the UE according to the conventional paging method. That is, the core network device sends a PAGING message to the base station through the interface between the base station and the core network to initiate a PAGING procedure, because the first version core network device does not have the capability of storing the coverage level of the UE, the PAGING message does not carry the coverage level of the UE. And the base station receives the paging message from the first edition core network equipment and pages the UE on the worst coverage level uniformly.
