technical field

Background technique

In a terrestrial communication system, a cell uniquely provides tracking area identification information for each network supported by the cell (such as a public land mobile network (Public Land Mobile Network, PLMN)). When a terminal accesses the network through a cell, the wireless access network determines the tracking area where the terminal is located based on the network information selected by the terminal, and informs the core network of this information through the N2 interface, so that the core network can manage the tracking area. However, in a satellite communication system, a cell provides multiple tracking area identifiers for each network supported by the cell. When a terminal accesses the network through a cell, the wireless access network cannot determine the tracking area where the terminal is located, and thus cannot provide the prepared tracking area information to the core network, which is not conducive to the core network to manage and maintain the tracking area of the terminal.

In this way, according to the fourth indication information and/or the fifth indication information, the tracking area of the terminal can be accurately acquired when the cell provides multiple tracking area coding information, thereby facilitating subsequent tracking area management and maintenance.

The present application will be described below in conjunction with specific embodiments.

Embodiment 1: The terminal reports the tracking area information of the terminal through AS signaling.

The method includes:

Step 0: In the target cell, the cell provides a plurality of tracking area coding information for the target network.

For example, the target cell 1 may provide access to the target network PLMN1, and for the target network PLMN1, the target cell provides two tracking area codes TAC1 and TAC2.

Step 1: The terminal initiates a wireless connection establishment process, and reports the tracking area information of the terminal to the radio access network device through AS signaling during the process.

For example, the terminal requests to access the network through the target network PLMN 1 of the target cell 1, and reports the tracking area information TAC1 of the terminal to the wireless access network during the establishment of the wireless connection.

Wherein, the wireless connection establishment process may be triggered by at least one of the following reasons:

(1) Initial registration. For example, after the terminal is powered on and resides in the target cell 1, the NAS layer triggers the initial location registration process to report the tracking area where the terminal is located to the core network equipment, and this process triggers the AS layer of the terminal to initiate a wireless connection establishment process.

(2) Mobile update registration. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. Cell 2 supports PLMN1 access, and cell 2 broadcasts TAC3 and TAC4 for the PLMN1. When the terminal moves from cell 1 to cell 2, the NAS layer of the terminal triggers the mobile location registration process to update the tracking area where the terminal is located to the core network, and this process triggers the AS layer of the terminal to initiate a wireless connection establishment process. As another example, cell 2 supports PLMN1 access, and for this PLMN1, cell 2 broadcasts TAC2 and TAC3, wherein TAC2 is a tracking area in which terminals are prohibited from registering, and TAC3 is a tracking area in which terminals are allowed to register. When the terminal moves from cell 1 to cell 2, the NAS layer of the terminal triggers the mobile location registration process to update the tracking area where the terminal is located to the core network, and this process triggers the AS layer of the terminal to initiate a wireless connection establishment process.

(3) Emergency registration. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. The terminal requests access to the network through the target network PLMN1 of the target cell 1 to obtain emergency services. This process triggers the AS layer of the terminal to initiate a wireless connection establishment process. During the establishment of the wireless connection, the terminal reports its own tracking area information to the network side through AS signaling.

Wherein, the terminal may report the tracking area information of the terminal to the radio access network in the following manner:

Wireless connection establishment complete message. For example, the terminal reports the tracking area information of the terminal to the radio access network through the RRCsetupcomplet message.

Wherein, the tracking area information of the terminal may be obtained based on positioning information, for example, the terminal obtains positioning information based on Global Navigation Satellite System (Global Navigation Satellite System, GNSS) positioning, or based on a 5G system (5G System, 5GS) assisted terminal Location Get location information. The terminal further acquires the tracking area where the terminal is located based on the mapping table of the geographic location and the tracking area and the positioning information.

Wherein, the terminal reports the tracking area information of the terminal in any of the following ways:

Track area code information. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. The terminal determines that it is in the tracking area corresponding to the tracking area code TAC2, and then reports the tracking area code TAC2 to the radio access network.

Track zone code index information. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. One way of implementation is: the index corresponding to the traditional tracking area coding field is 0, and the newly introduced tracking area coding list assigns indexes to the tracking area coding elements in the list sequentially starting from 1. When the terminal determines the tracking area code where it is located, it reports the corresponding tracking area code index to the radio access network. As another implementation manner, the index corresponding to the traditional tracking area coding field is 1, and the newly introduced tracking area coding list assigns indexes to the tracking area coding elements in the list sequentially starting from 2. Wherein, the above-mentioned newly introduced tracking area coding list is the tracking area coding introduced for non-terrestrial communication systems (such as satellite communication systems), and the above-mentioned traditional tracking area coding field refers to the tracking area coding field for terrestrial communication information. Of course, as another implementation manner, the target cell 1 does not provide the traditional tracking area coding field for the target network PLMN1, but introduces a new tracking area coding list field. For example, trackareacodelist={TAC1, TAC2}, where TAC1 corresponds to tracking area code index 0, and TAC1 corresponds to tracking area code index 1. The terminal determines the tracking area coding index, and reports the tracking area coding index to the network side.

In this embodiment of the application, the behavior of the terminal to report the tracking area information may be stipulated in the protocol, or based on the wireless access network configuration. For example, the protocol stipulates that when the terminal detects that a certain network (such as PLMN) supported by the cell When there is no tracking area information, the terminal always reports the tracking area of the terminal. For another example, based on the indication information configured on the network side (the indication information is provided through system information), the indication information indicates whether the tracking area information of the terminal needs to be reported. The indication information may be one-bit indication information, for example, when the value of the indication information is 0, it is used to instruct the terminal to report tracking area information, or when the value of the indication information is 1, it is used to indicate that the terminal does not Report tracking area information. Certainly, when the indication information exists, it may be used to instruct the terminal to report the tracking area information, and when the indication information does not exist, it may be used to instruct the terminal not to report the tracking area information. For the network side, when a certain network (such as PLMN) supported by the cell corresponds to multiple tracking area information belonging to the same registration area, the wireless access network side sets the indication information to instruct the terminal not to report the tracking of the terminal area information, or the system information does not carry the indication information. When multiple tracking area information corresponding to a certain network supported by the cell do not belong to the same registration area, the network side sets the indication information to instruct the terminal to report the tracking area information of the terminal, or carries the tracking area information in the system information instructions described above. Additionally, the wireless access network device and the access network device need to exchange in advance whether the multiple tracking area information corresponding to the target network supported by the wireless access network device belongs to the same registration area.

It should be noted that the indication information in this embodiment may be equivalent to the first indication information in this application, where the first indication information is provided by radio access network equipment through broadcast signaling (such as through SIB1) .

Step 2: The radio access network device determines the tracking area where the terminal is located according to the tracking area information reported by the terminal, and provides it to the core network device.

For example, if the terminal reports tracking area coding information, the tracking area coding information is indicated to the core network device. For another example, if the terminal reports the tracking area code index information, the tracking area code corresponding to the tracking area where the terminal is located is determined according to the preset index allocation rule, and the tracking area code is indicated to the core network device.

Step 3: The core network device determines the tracking area where the terminal is located based on the tracking area information provided by the radio access network device, for subsequent tracking area management.

Embodiment 2: The terminal reports the tracking area information of the terminal through NAS signaling.

The method includes:

Step 0: In the target cell, the cell provides a plurality of tracking area coding information for the target network.

For example, the target cell 1 may provide access to the target network PLMN 1, and for the target network PLMN 1, the target cell provides two tracking area codes TAC 1 and TAC2.

Step 1: The terminal initiates a wireless connection establishment process, and reports the tracking area information of the terminal to the core network through NAS signaling during the process.

For example, the terminal requests to access the network through the target network PLMN 1 of the target cell 1, and reports the tracking area information TAC1 of the terminal to the core network during the establishment of the wireless connection.

Wherein, the wireless connection establishment process may be triggered by at least one of the following reasons:

(1) Initial Registration. For example, after the terminal is powered on and resides in the target cell 1, the NAS layer triggers the initial location registration process to report the tracking area where the terminal is located to the core network equipment, and this process triggers the AS layer of the terminal to initiate a wireless connection establishment process.

(2) Mobile update registration. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. Cell 2 supports PLMN1 access, and cell 2 broadcasts TAC3 and TAC4 for the PLMN1. When the terminal moves from cell 1 to cell 2, the NAS layer of the terminal triggers the mobile location registration process to update the tracking area where the terminal is located to the core network, and this process triggers the AS layer of the terminal to initiate a wireless connection establishment process. As another example, cell 2 supports PLMN1 access, and for this PLMN1, cell 2 broadcasts TAC2 and TAC3, wherein TAC2 is a tracking area in which terminals are prohibited from registering, and TAC3 is a tracking area in which terminals are allowed to register. When the terminal moves from cell 1 to cell 2, the NAS layer of the terminal triggers the mobile location registration process to update the tracking area where the terminal is located to the core network, and this process triggers the AS layer of the terminal to initiate a wireless connection establishment process.

(3) Emergency registration. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. The terminal requests access to the network through the target network PLMN1 of the target cell 1 to obtain emergency services. This process triggers the AS layer of the terminal to initiate a wireless connection establishment process. During the establishment of the wireless connection, the terminal reports its own tracking area information to the network side through NAS signaling. Wherein, the terminal may report the tracking area information of the terminal to the radio access network in the following manner:

The NAS container in the wireless connection establishment complete message. For example, the terminal reports the tracking area information of the terminal to the core network through the NAS container of the RRCsetupcomplet message.

Wherein, the tracking area information where the terminal is located may be acquired based on positioning information. For example, the terminal acquires positioning information based on GNSS positioning. Alternatively, the positioning information is obtained based on 5GS-assisted terminal positioning. The terminal further acquires the tracking area where the terminal is located based on the mapping table of the geographic location and the tracking area and the positioning information.

Wherein, the terminal reports the tracking area information of the terminal in any of the following ways:

Track area code information. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. The terminal determines that it is in the tracking area corresponding to the tracking area code TAC2, and then reports the tracking area code TAC2 to the radio access network.

Track zone code index information. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. One way of implementation is: the index corresponding to the traditional tracking area coding field is 0, and the newly introduced tracking area coding list assigns indexes to the tracking area coding elements in the list sequentially starting from 1. When the terminal determines the tracking area code where it is located, it reports the corresponding tracking area code index to the radio access network. As another implementation manner, the index corresponding to the traditional tracking area coding field is 1, and the newly introduced tracking area coding list assigns indexes to the tracking area coding elements in the list sequentially starting from 2. Wherein, the above-mentioned newly introduced tracking area coding list is the tracking area coding introduced for non-terrestrial communication systems (such as satellite communication systems), and the above-mentioned traditional tracking area coding field refers to the tracking area coding field for terrestrial communication information. Of course, as another implementation manner, the target cell 1 does not provide the traditional tracking area coding field for the target network PLMN1, but introduces a new tracking area coding list field. For example, trackareacodelist={TAC1, TAC2}, where TAC1 corresponds to tracking area code index 0, and TAC1 corresponds to tracking area code index 1. The terminal determines the tracking area coding index, and reports the tracking area coding index to the network side.

It should be noted that the at least two pieces of tracking area information corresponding to the target network PLMN1 are provided by the AS layer of the terminal to the NAS layer of the terminal. Exemplarily, the AS layer of the terminal provides at least two tracking area information corresponding to the target network PLMN1 to the NAS layer of the terminal in the sequence of first providing the traditional tracking area code field and then the newly introduced tracking area code list field.

Wherein, the behavior of reporting the tracking area information of the terminal may be a protocol agreement, or may be based on wireless access network configuration. The details are the same as in Embodiment 1.

Step 2: The wireless access network device forwards the NAS information carrying the tracking area coding information reported by the terminal to the core network device. In addition, when the radio access network device provides the location information of the terminal to the core network device, the behavior of the radio access network can be any of the following:

Randomly select one of multiple tracking area coding information corresponding to the target network and place it in the location information and provide it to the core network; for example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for this PLMN1. The terminal requests access from the target network PLMN1, and the wireless access randomly selects a tracking area code corresponding to the target network, such as TAC1, and provides it to the core network. Specifically, the radio access network randomly places a tracking area code such as TAC1 in a user location information IE (userlocation information IE) indicated to the core network.

All the multiple tracking area coding information corresponding to the target network are placed in the location information and provided to the core network; for example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. The terminal requests access from the target network PLMN1, and the wireless access provides all tracking area codes TAC1 and TAC2 corresponding to the target network to the core network. Specifically, the radio access network places tracking area codes corresponding to all target networks PLMN1 in the user location information IE indicated to the core network.

The tracking area corresponding to the target network is not provided in the location information. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. The terminal requests access from the target network PLMN1, and the wireless access does not provide the tracking area code corresponding to the target network. Specifically, the radio access network does not place the tracking area code in the user location information IE indicated to the core network.

Step 3: The core network device receives the NAS information carrying the tracking area code information reported by the terminal forwarded by the wireless access network, and determines the tracking area where the terminal is based on the NAS information for subsequent tracking area management.

For example, if the terminal reports tracking area coding information, the tracking area of the terminal is determined according to the tracking area coding information. For another example, if the terminal reports tracking area coding index information, the core network device determines the tracking area of the terminal according to the tracking area coding index information. A specific implementation manner may be that the tracking area code index is indicated to the radio access network, and the radio access network feeds back the tracking area code corresponding to the tracking area code index to the core network. Alternatively, the core network extracts a preset tracking area code index allocation rule from the radio access network, and determines the tracking area code corresponding to the tracking area where the terminal is located based on the rule.

In addition, the core network device ignores the tracking area coding information provided by the radio access network through the location information.

Embodiment 3: The core network device triggers the terminal to report tracking area information.

Step 0: In the target cell, the cell provides a plurality of tracking area coding information for the target network.

For example, the target cell 1 may provide access to the target network PLMN1, and for the target network PLMN1, the target cell provides two tracking area codes TAC1 and TAC2.

Step 1: The terminal initiates a wireless connection establishment process, requesting access to the target network through the target cell. Wherein, the wireless connection establishment process may be triggered by at least one of the following reasons:

(1) Initial location registration. For example, after the terminal is powered on and resides in the target cell 1, the NAS layer triggers the initial location registration process to report the tracking area where the terminal is located to the core network, and this process triggers the AS layer of the terminal to initiate a wireless connection establishment process.

(2) Mobile location registration. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. Cell 2 supports PLMN1 access, and cell 2 broadcasts TAC3 and TAC4 for the PLMN1. When the terminal moves from cell 1 to cell 2, the NAS layer of the terminal triggers the mobile location registration process to update the tracking area where the terminal is located to the core network, and this process triggers the AS layer of the terminal to initiate a wireless connection establishment process. As another example, cell 2 supports PLMN1 access, and for this PLMN1, cell 2 broadcasts TAC2 and TAC3, wherein TAC2 is a tracking area in which terminals are prohibited from registering, and TAC3 is a tracking area in which terminals are allowed to register. When the terminal moves from cell 1 to cell 2, the NAS layer of the terminal triggers the mobile location registration process to update the tracking area where the terminal is located to the core network, and this process triggers the AS layer of the terminal to initiate a wireless connection establishment process.

(3) Emergency registration. For example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. The terminal requests access to the network through the target network PLMN1 of the target cell 1 to obtain emergency services. Step 2: When the radio access network provides the location information of the terminal to the core network, the behavior of the radio access network is as follows:

All the multiple tracking area coding information corresponding to the target network are placed in the location information and provided to the core network; for example, cell 1 supports PLMN1 access, and cell 1 broadcasts TAC1 and TAC2 for the PLMN1. The terminal requests access from the target network PLMN1, and the wireless access provides all tracking area codes TAC1 and TAC2 corresponding to the target network to the core network. Specifically, the radio access network places tracking area codes corresponding to all target networks PLMN1 in the user location information IE indicated to the core network.

Step 3: The core network equipment receives the location information of the terminal provided by the wireless access network. Based on the plurality of tracking area coding information carried in the location information, the terminal is triggered to report the tracking area information where it is located.

Exemplarily, the behavior of the core network is as follows:

If the tracking areas corresponding to multiple tracking area coding information carried in the location information of the terminal do not belong to the same registration area, the terminal is triggered to report the tracking area information where it is located.

If the tracking areas corresponding to multiple tracking area coding information carried in the location information of the terminal belong to the same registration area, the terminal is not triggered to report the tracking area information where it is located. In addition, the core network provides the tracking area list belonging to the registration area to the terminal to assist its subsequent tracking area management.

Step 4: Based on the instructions of the core network, the terminal reports the tracking area information where the terminal is located. The reporting method can be any of the following:

Through AS signaling reporting, the radio access network device determines the tracking area code corresponding to the tracking area where the terminal is located, and provides it to the core network device. For the specific tracking area information reported by the terminal and the behavior of the corresponding radio access network device, refer to Embodiment 1;

Through NAS signaling reporting, the core network device determines the tracking area code corresponding to the tracking area where the terminal is located based on the tracking area information reported by the terminal. For the specific tracking area information reported by the terminal and the behavior of the corresponding core network device, refer to Embodiment 2.
