Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a paging method, device and network element. Background Art

[0002] To further meet the need for low power consumption and wide coverage, 5G currently introduces mMTC (Massive Machine Type Communication) low-power wide-area devices (i.e., eMTC / NB-IoT devices based on the IoT technology evolved from LTE). This is to enhance NR (New Radio) to address the following needs in the Industrial Internet of Things and other vertical fields (i.e., the middle area of ​​the capability triangle):

[0003] Industrial wireless sensors with low latency (5-10ms) and medium data rates (<2Mbps);

[0004] Medium-high speed data transmission (2-25Mbps) video transmission;

[0005] High data rate wearable devices (5-50Mbps) with long battery life (1-2 weeks).

[0006] These capabilities are higher than those required for mMTC, but lower than those for eMBB (Enhanced Mobile Broadband) and URLLC (Ultra-reliable and Low Latency Communications). Therefore, plans are underway to introduce RedCap (RedCap) terminal access.

[0007] 5G networking solutions are divided into SA (Standalone) and NSA (Non-Standalone). In SA networking, there is no bearer separation on the user plane, and the terminal only needs one wireless connection (Long Term Evolution LTE or NR).

[0008] With subsequent network construction, scenarios may arise where both NG-eNBs (such as NB-IoT / eMTC) and gNBs (such as RedCap) are connected to the 5G core network (5GC) simultaneously. NG-eNBs support eDRX (Extended Discontinuous Reception) (a terminal with eDRX enabled is not always reachable by paging; it is only reachable during the paging time window (PTW).) However, gNB base stations do not currently support eDRX. When a terminal supporting both radio access technologies is idle, the core network does not know which base station is currently providing coverage for the terminal, and paging attempts may fail.

[0077] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0078] In order to solve the problem of paging unreachable, such as Figure 1 As shown, the embodiment of the present invention further provides a paging method, including:

[0079] Step 101: When a terminal supports a first radio access technology type and a second radio access technology type, or when a tracking area list in which the terminal is located includes the first radio access technology type and the second radio access technology type, and the terminal supports the first radio access technology type and the second radio access technology type, a first network element first sends a paging message to a second base station;

[0080] Step 102: If the paging message does not reach the terminal, wait for the eDRX paging time window of the first base station to arrive, and then the first network element sends a paging message to the first base station within the eDRX paging time window;

[0081] The first base station supports a first radio access technology type, and the second base station supports a second radio access technology type.

[0082] In this embodiment, if the first paging of the terminal by the second base station is unreachable, it indicates that the terminal is not currently in the second radio access technology type, which implicitly indicates that the terminal is currently in the first radio access technology type. In order to ensure that the paging is reachable, the first network element sends a paging message to the first base station within the eDRX paging time window, which can ensure that the paging is reachable.

[0083] In at least one alternative embodiment of the present invention, Figure 2 As shown, the embodiment of the present invention further provides a paging method, including:

[0084] Step 201: When a terminal supports a first radio access technology type and a second radio access technology type, or when a tracking area list in which the terminal is located includes the first radio access technology type and the second radio access technology type, and the terminal supports the first radio access technology type and the second radio access technology type, a first network element sends a paging message to a first base station or a second base station that was last reachable by the terminal.

[0085] Step 202: If the paging does not reach the terminal, the first network element sends corresponding paging messages to the first base station and the second base station respectively;

[0086] The first base station supports a first radio access technology type, and the second base station supports a second radio access technology type.

[0087] In this embodiment, if the paging call from the last reachable base station is unreachable, the terminal is not in the radio access technology type corresponding to the base station. The first network element then sends corresponding paging messages to the first base station and the second base station, respectively. If the paging call from the second base station to the terminal is unreachable, it indicates that the terminal is not currently in the second radio access technology type. If the paging call from the first base station to the terminal is also unreachable, and the terminal is not in the second radio access technology type, it indicates that the terminal is in the non-paging time window of the first radio access technology type. To ensure that the paging is reachable, the first network element sends a paging message to the first base station within the eDRX paging time window, thereby ensuring that the paging is reachable.

[0088] In at least one alternative embodiment of the present invention, Figure 3 As shown, the embodiment of the present invention further provides a paging method, including:

[0089] Step 301: When a terminal supports a first radio access technology type and a second radio access technology type, or when a tracking area list in which the terminal is located includes the first radio access technology type and the second radio access technology type, and the terminal supports the first radio access technology type and the second radio access technology type, a first network element sends a paging message to a first base station and a second base station.

[0090] The first base station supports a first radio access technology type, and the second base station supports a second radio access technology type.

[0091] In the above-mentioned embodiments of the present invention, when the terminal supports the first radio access technology type and the second radio access technology type, or when the tracking area list of the terminal includes the first radio access technology type and the second radio access technology type, and the terminal supports the first radio access technology type and the second radio access technology type, the corresponding paging mechanism is used to page the terminal, thereby solving the problem of unreachable paging after the terminal turns on eDRX.

[0092] Optionally, the first network element mentioned in the embodiment of the present invention includes: AMF (Access and Mobility Management Function), or SMF (Session Management Function), or other core network elements with management functions; no specific limitation is made here.

[0093] In at least one optional embodiment of the present invention, the above-mentioned first wireless access technology type includes: at least one of WB-E-UTRA (Wideband Evolved UMTS Terrestrial Radio Access), NB-IoT (Narrowband Internet of Things), and eMTC (Enhanced Machine Type Communications); the above-mentioned second wireless access technology type includes: at least one of NR (New Radio) and RedCap (Capability Tailoring).

[0094] In at least one embodiment of the present invention, the first radio access technology type supports eDRX, and the second radio access technology type does not support eDRX.

[0095] In at least one embodiment of the present invention, the method further comprises:

[0096] The first network element determines, based on the radio access type information reported by the first base station and the second base station, whether the paging messages corresponding to the first base station and the second base station respectively carry the eDRX paging time window information.

[0097] The first network element determines, according to the wireless access type information reported by the first base station and the second base station, the paging messages corresponding to the first base station and the second base station, respectively, including:

[0098] When the radio access type information reported by the first base station indicates that the first base station supports a first radio access technology type, determining that a paging message corresponding to the first base station carries eDRX paging time window information;

[0099] and / or,

[0100] When the radio access type information reported by the second base station indicates that the second base station supports a second radio access technology type, it is determined that the paging message corresponding to the second base station does not carry eDRX paging time window information.

[0101] As an optional embodiment, the first network element determines whether the tracking area list where the terminal is located includes the first radio access technology type and the second radio access technology type in the following manner;

[0102] The tracking area list where the terminal is located has a first flag, and the tracking area list includes a first radio access technology type and a second radio access technology type.

[0103] As another optional embodiment, the first network element determines whether the terminal supports the first radio access technology type and the second radio access technology type in the following manner;

[0104] If the terminal has the second flag, the terminal supports the first radio access technology type and the second radio access technology type.

[0105] For example, in an embodiment of the present invention, a first network element locally performs a first marking on a tracking area list (TAList) and a second marking on a terminal. The first marking of the TAList indicates that the tracking area list includes both the first radio access technology type and the second radio access technology type; the second marking of the terminal indicates that the terminal supports both the first radio access technology type and the second radio access technology type, and that eDRX is enabled for the terminal.

[0106] In at least one optional embodiment of the present invention, the method further comprises:

[0107] Obtaining the radio access type RAT information (RAT information) and / or RAT category information (RAT Category information) corresponding to the tracking area list;

[0108] When it is determined according to the RAT information and / or RAT classification information that the tracking area list includes a first radio access technology type and a second radio access technology type, a first mark is performed on the tracking area list.

[0109] For example, the NG SETUP REQUEST message sent by the NG-RAN to the AMF carries the RAT information and / or RAT classification information corresponding to the supported TAList. The RAT information includes: RAT information associated with the tracking area code (TAC) of the indicated PLMN. Optionally, the core network device updates the locally stored tracking area list based on the RAT information.

[0110] The RAT classification information is used to directly indicate whether the corresponding TAList includes the first radio access technology type and the second radio access technology type. For example, when the value of the RAT classification information is the first value, the tracking area list includes the first radio access technology type and the second radio access technology type; if the value of the RAT classification information is other than the first value, it indicates that the corresponding tracking area list only includes the first radio access technology type, or only includes the second radio access technology type, which is not specifically limited here.

[0111] In at least one optional embodiment of the present invention, the method further comprises:

[0112] Get the RAT information supported by the terminal;

[0113] According to the RAT information supported by the terminal and the negotiated eDRX usage, it is determined that the terminal supports the first radio access technology type and the second radio access technology type, and the specific paging indication field of the terminal is set to a second value.

[0114] For example, the terminal initiates a registration request message, which carries the terminal wireless capabilities (used to indicate the RAT type supported for access by the current terminal) and the extended idle mode DRX parameters (used to request the use of eDRX) in the registration request message; the core network device makes a judgment based on the terminal wireless capabilities and the negotiated eDRX usage. If the current terminal supports both the first radio access technology type and the second radio access technology type, and the user has turned on eDRX, the core network device sets the "specific paging indication field" in the local UE context information (i.e., sets it to the second value).

[0115] When paging is required, the first network element queries the "multi-mode terminal specific paging indication field" to determine that the current terminal is a multi-mode terminal and eDRX is turned on, and based on the first mark, determines that the TA list in which the current terminal is located is a TA list that is a mixture of the first wireless access technology type and the second wireless access technology type. The core network device then determines to use a specific paging mechanism to page the terminal.

[0116] As an optional embodiment, the "Specific Paging Indication Field" is a new field in the terminal context. If the "Specific Paging Indication Field" is the second value, it indicates that the current terminal uses both the first radio access technology type and the second radio access technology type, and eDRX is enabled under the first radio access technology type, requiring a special paging method. If the "Specific Paging Indication Field" is another value, it indicates that the current terminal uses only the first radio access technology type or only the second radio access technology type, requiring a normal paging method.

[0117] like Figure 4 As shown, an embodiment of the present invention further provides a paging device, including:

[0118] The first paging module 401 is configured to first send a paging message to the second base station when the terminal supports the first radio access technology type and the second radio access technology type, or when the tracking area list where the terminal is located includes the first radio access technology type and the second radio access technology type and the terminal supports the first radio access technology type and the second radio access technology type;

[0119] The second paging module 402 is configured to wait for the eDRX paging time window of the first base station to arrive if the paging does not reach the terminal, and then send a paging message to the first base station within the eDRX paging time window;

[0120] The first base station supports a first radio access technology type, and the second base station supports a second radio access technology type.

[0121] As an optional embodiment, the first radio access technology type supports eDRX, and the second radio access technology type does not support eDRX.

[0122] As an optional embodiment, the device further includes:

[0126] and / or,

[0127] The second determining submodule is configured to determine that the paging message corresponding to the second base station does not carry the eDRX paging time window information when the radio access type information reported by the second base station indicates that the second base station supports a second radio access technology type.

[0128] In the above-mentioned embodiments of the present invention, when the terminal supports the first radio access technology type and the second radio access technology type, or when the tracking area list of the terminal includes the first radio access technology type and the second radio access technology type, and the terminal supports the first radio access technology type and the second radio access technology type, the corresponding paging mechanism is used to page the terminal, thereby solving the problem of unreachable paging after the terminal turns on eDRX.
