Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication technology, in particular to a method and device for determining a networking type supported by a cell. BACKGROUND

[0002] In a fifth-generation (5G) New Radio (NR) system, in a Long Time Evolution (LTE) or Evolved Long Term Evolution (eLTE) and NR heterogeneous system deployment scenario, an LTE or eLTE base station can configure a terminal device to measure a measurement report of an NR cell. According to the deployment of the NR cell, the networking type supported by the NR cell includes:

[0003] (1) Non-Stand Alone (NSA):

[0004] The NR cell is not connected to a 5G core network: the NR cell cannot be independently deployed in a network.

[0005] The cell is only used for Evolved Universal Terrestrial Radio Access (E-UTRA)-NR dual connectivity (referred to as EN-DC) or Next Generation Radio Access Networks (NG-RAN) E-UTRA-NR dual connectivity (referred to as NGEN-DC), for example: LTE-NR or eLTE-NR dual connectivity, in which the LTE or eLTE base station is the master node and the NR base station is the secondary node. In the cell system information, the NSA cell can not broadcast the System Information Block 1 (SIB1).

[0006] (2) Stand Alone (SA):

[0007] The NR is connected to a 5G core network: the NR cell can be independently deployed in a network, that is, Stand Alone (SA). In the cell system information, the SA cell must broadcast the SIB1.

[0008] (3) SA and NSA (SA+NSA)

[0009] The networking type supported by the NR cell can be SA and NSA (SA+NSA). In the cell system information, the SA and NSA cell must broadcast the SIB1.

[0010] So when the terminal device reports the measurement report of the NR cell, if the LTE or eLTE base station does not read the SIB1 of the NR cell from the measurement report of the NR cell reported by the terminal device, the LTE or eLTE base station knows that the NR cell is only an NSA cell. The LTE or eLTE base station knows that only the interface of the dual connectivity can be established with the NR cell.

[0011] However, when the terminal device reports the measurement report of the NR cell, if the measurement report of the NR cell reported by the terminal device includes the SIB1 information of the NR cell, the LTE or eLTE base station cannot judge that the NR cell supports NSA, or SA, or SA and NSA, resulting in that the LTE or eLTE base station cannot determine what kind of neighbor relationship is established with the NR cell.

[0063] In order to better understand the embodiments of the present application, the following is first introduced: in order to automatically add a neighbor cell, when a serving base station receives a measurement report reported by a terminal device, if it is found that the measurement result reported contains a measurement result of an unknown cell (a physical cell identifier (PCI) is an unknown PCI), the base station can select the terminal device, and then issue a measurement configuration (RRC_CONN_RECFG) message for establishing, changing or releasing, to instruct the terminal device to measure global cell identifier (CGI), tracking area code (TAC), public land mobile network (PLMN) and the like of the unknown cell.

[0064] If the terminal device successfully reads the CGI, TAC, PLMN and the like of the cell, the terminal device will report the CGI, TAC, PLMN and the like to the base station. After the base station receives the CGI, TAC, PLMN and the like reported by the terminal device, the base station can automatically add the cell as a neighbor cell. The neighbor cell addition function needs to establish an X2 interface or an Xn interface or an X2+Xn interface with the neighbor cell.

However, the following description describes NR systems for illustrative purposes, and NR terminology is used in most of the following description, although these techniques can also be applied to applications beyond NR systems.

[0069] Embodiments of the present invention are described below with reference to the accompanying drawings. The methods and devices provided in these embodiments for determining the supported network types of a cell can be applied to wireless communication systems. (Reference) Figure 1 This is a schematic diagram of the architecture of a wireless communication system provided in an embodiment of the present invention. Figure 1 As shown, the wireless communication system may include a network device 10 and a terminal device, for example, a terminal device denoted as UE11. UE11 can communicate with the network device 10 (transmit signaling or data). In practical applications, the connection between the above devices can be a wireless connection. For ease of intuitive representation of the connection relationship between the devices, solid lines are used in the figure. It should be noted that the above communication system may include multiple UE11s, and the network device 10 can communicate with multiple UE11s.

[0070] The terminal devices provided in the embodiments of the present invention can be mobile phones, tablet computers, laptops, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), mobile internet devices (MIDs), wearable devices, or in-vehicle devices, etc.

[0071] The network device 10 provided in this embodiment of the invention can be a base station. The base station can be a commonly used base station, an evolved node base station (eNB), or a network device in a 5G system (e.g., a next-generation node base station (gNB) or a transmission and reception point (TRP)).

[0072] See Figure 2 This invention provides a method for determining the network type supported by a cell. The execution subject can be a network device, and the specific steps are as follows:

[0073] Step 201: Receive the measurement report of the target cell from the terminal device;

[0074] The target cell can be an NR cell. The network device can be an LTE base station or an eLTE base station, and the scenario of the embodiment of the present application can be an LTE or eLTE and NR heterogeneous system deployment scenario, but is not limited thereto.

[0075] Step 202: When the measurement report includes the related information of SIB1, it is determined that the target cell supports standalone networking (SA).

[0076] The related information of SIB1 can be used to indicate that the content in SIB1 is incomplete.

[0077] For example, when SIB1 includes A, B and C, when the SIB1 in the measurement report includes only A and C, or A and B, or B and C, the content in the SIB1 is incomplete.

[0078] In the embodiment of the present application, optionally, before step 201 or step 202, or after step 201 or step 202, or when step 201 or step 202 is executed, the method can further include: sending a first message, the first message being used to indicate that SIB1 is not broadcasted.

[0079] It can be understood that in the embodiment of the present application, the following restriction can be made in the NR system: the NSA cell does not broadcast SIB1, that is, the type of the NR cell broadcasting SIB1 can only be SA, and the type of the NR cell cannot be SA and NSA at the same time. In this way, the network device can immediately determine the networking type supported by the NR cell according to the measurement report of the terminal device.

[0080] In the embodiment of the present application, the network device can determine the networking type supported by the NR cell as SA or NSA based on the measurement report, which is beneficial to better planning of the network adjacent cell relationship by the operator.

[0081] Referring to Figure 3 The embodiment of the present application also provides a method for determining the networking type supported by a cell, and the execution subject of the method can be a terminal device, and the specific steps are as follows:

[0082] Step 301: sending a measurement report of a target cell to a network device, when the measurement report includes related information of SIB1, indicating that the target cell supports standalone networking (SA).

[0083] The related information of SIB1 can be used to indicate that the content in SIB1 is incomplete.

[0084] The target cell can be an NR cell. The network device can be an LTE base station or an eLTE base station, and the scenario of the embodiment of the present application can be an LTE or eLTE and NR heterogeneous system deployment scenario, but is not limited thereto.

[0085] In the embodiments of the present application, before step 301, or after step 301, or when step 301 is performed, the method can further comprise: receiving a first message from the network device, the first message being used to indicate that the SIB1 is not broadcasted.

[0086] It can be understood that, in the embodiments of the present application, the following restriction can be made in the NR system: the NSA cell does not broadcast the SIB1, that is, the type of the NR cell broadcasting the SIB1 can only be SA. The type of the NR cell cannot be SA and NSA at the same time. In this way, the network device can immediately determine whether the type of the NR cell is SA or NSA according to the measurement report of the terminal device.

[0087] In the embodiments of the present application, the network device can determine that the networking type supported by the NR cell is SA or NSA based on the measurement report, which is beneficial to the operator to better plan the adjacent cell relationship of the network.

[0088] Referring to Figure 4 The embodiments of the present application also provide a method for determining the networking type supported by a cell, and the execution subject of the method can be a network device, and the specific steps are as follows:

[0089] Step 401: receiving a measurement report of a target cell from a terminal device, wherein the measurement report comprises: related information of SIB1 and / or first indication information, the first indication information being used to indicate the networking type (for example: SA, NSA, or SA+NSA, etc.) supported by the target cell;

[0090] It can be understood that the related information of SIB1 in the measurement report can be replaced by related information of Remaining Minimum System Information (RMSI), that is, the content included in the measurement report can be: related information of RMSI and / or first indication information.

[0091] The target cell can also be referred to as an NR cell. The network device can be an LTE base station or an eLTE base station, and the scenario of the embodiments of the present application can be an LTE or eLTE and NR heterogeneous system deployment scenario, but is not limited thereto.

[0092] The related information of SIB1 can be used to indicate whether the content in the SIB1 is complete.

[0093] In the embodiments of the present application, the content included in the measurement report can be divided into the following three cases:

[0094] (1) The measurement report can include: related information of SIB1;

[0095] (2) The measurement report can comprise first indication information.

[0096] (3) The measurement report can comprise related information of SIB1 and first indication information.

[0097] Step 402: Determine the networking type supported by the target cell according to the related information of SIB1 and / or the first indication information.

[0098] It can be understood that the networking type supported by the target cell can be determined in step 402 in the following three ways:

[0099] Way 1: Determine the type of the target cell according to the first indication information.

[0100] Way 2: Determine the networking type supported by the target cell according to the related information of SIB1.

[0101] Way 3: Determine the networking type indicated by the target cell according to the related information of SIB1 and the first indication information.

[0102] In the embodiment of the application, the measurement report comprises first indication information, wherein the first indication information comprises first bit information and / or second bit information.

[0103] Optionally, the first bit information can represent whether the target cell supports SA, and the second bit information can represent whether the target cell supports NSA. Alternatively, the first bit information is used to represent whether the target cell supports NSA, and the second bit information is used to represent whether the target cell supports SA.

[0104] Optionally, the way 1 in step 402 can be implemented in any of the following ways:

[0105] (1) When the value of the first bit information is a first value, and / or the value of the second bit information is a second value, it is determined that the target cell supports standalone networking (SA).

[0106] For example, when the value of the first bit information is 1, and / or the value of the second bit information is 0, it is determined that the target cell supports standalone networking.

[0107] (2) When the value of the first bit information is the second value, and / or the value of the second bit information is the first value, it is determined that the target cell supports non-standalone networking (NSA).

[0108] For example, when the value of the first bit information is 0, and / or the value of the second bit information is 1, it is determined that the target cell supports non-standalone networking.

[0109] (3) when the first bit information has a first value and the second bit information has a first value, it is determined that the target cell supports non-standalone networking and standalone networking (SA+NSA);

[0110] That is, when the value of the first bit information and the value of the second bit information are the same, it is determined that the target cell supports non-standalone networking and standalone networking. For example: when the value of the first bit information is 1 and the value of the second bit information is 1, it is determined that the target cell supports non-standalone networking and standalone networking.

[0111] (4) when the first bit information has a second value and the second bit information has a second value, it is determined that the target cell supports a first type, wherein the system information broadcast by the cell of the first type does not contain SIB1 (or RMSI).

[0112] That is, when the value of the first bit information and the value of the second bit information are the same, it is determined that the target cell supports the first type. For example: when the value of the first bit information is 0 and the value of the second bit information is 0, it is determined that the target cell supports the first type.

[0113] In the embodiment of the application, optionally, the measurement report comprises: related information of SIB1.

[0114] Optionally, the manner 2 in step 402 can be implemented by any one of the following manners:

[0115] When the related information of SIB1 indicates that the content in SIB1 is complete, it is determined that the target cell supports standalone networking (SA);

[0116] When the related information of SIB1 indicates that the content in SIB1 is not complete, it is determined that the target cell supports non-standalone networking (NSA).

[0117] Optionally, the content in SIB1 being not complete can mean at least one of the following: SIB1 has no TAC, SIB1 has no paging information, and SIB1 has no random access channel (RACH) information.

[0118] Taking whether SIB1 contains TAC as an example, when SIB1 has no TAC, it indicates that the content of SIB1 is not complete, and when SIB1 has TAC, it indicates that the content of SIB1 is complete. For example: when SIB1 includes PLMN but has no TAC, the target cell supports NSA; when SIB1 includes PLMN and TAC, the target cell supports SA.

[0119] For example, taking whether SIB1 contains paging information as an example, when SIB1 does not contain paging information, it indicates that the content of SIB1 is incomplete, and when SIB1 contains paging information, it indicates that the content of SIB1 is complete. For example: when SIB1 includes a PLMN but does not contain paging information, the target cell supports NSA. When SIB1 includes a PLMN and paging information, the target cell supports SA.

[0120] For example, taking whether SIB1 contains RACH information as an example, when SIB1 does not contain RACH information, it indicates that the content of SIB1 is incomplete, and when SIB1 contains RACH information, it indicates that the content of SIB1 is complete. For example: when SIB1 includes a PLMN but does not contain RACH information, the target cell supports NSA; when SIB1 includes a PLMN and RACH information, the target cell supports SA.

[0121] It can be understood that in the above-mentioned manner 1 and manner 2, two bits can be set in SIB1 of the NR cell, for indicating whether the NR cell supports NSA, or whether the NR cell supports SA, or whether the NR cell supports SA and NSA, or there is no SIB1 (or RMSI) in the system information of the NR cell. For example: the first bit has a value of 1 or 0, and the second bit has a value of 0 or 1.

[0122] (1) The first bit indicates whether the NR cell supports SA, and the second bit indicates whether the NR cell supports NSA.

[0123] When the values of the first bit and the second bit are equal, it indicates that the NR cell supports NSA+SA, or there is no RMSI in the system information of the NR cell.

[0124] In this way, when the terminal device reports a measurement report of the NR cell, the bit value in SIB1 can be used to determine whether the NR cell supports the networking type of NSA, SA or SA+NSA.

[0125] (2) The first bit indicates whether the NR cell supports NSA, and the second bit indicates whether the NR cell supports SA.

[0126] When the values of the first bit and the second bit are equal, it indicates that the NR cell supports NSA+SA, or there is no RMSI in the system information of the NR cell.

[0127] In this way, when the terminal device reports a measurement report of the NR cell, the bit value in SIB1 can be used to determine whether the NR cell supports the networking type of NSA, SA or SA+NSA.

[0128] Optionally, the manner 3 in step 402 can be implemented by the following manner:

[0129] The measurement report comprises: the related information of the SIB1 and the first indication information, the first indication information comprises third bit information, and the third bit information is used for indicating that the target cell supports independent networking and non-independent networking.

[0130] When the related information of the SIB1 indicates that the content in the SIB1 is complete, and the third indication information takes the third value, it is determined that the target cell supports independent networking and non-independent networking (SA+NSA).

[0131] Further, the third indication information can be 1-bit information, for example, the third indication information takes 1 or 0, of course, not limited thereto. The third indication information taking 1 or 0 can be used for indicating that the type of the target cell is SA+NSA.

[0132] Taking whether the SIB1 contains the TAC as an example, when the SIB1 does not contain the TAC, it indicates that the content of the SIB1 is incomplete, and when the SIB1 contains the TAC, it indicates that the content of the SIB1 is complete. For example, when the SIB1 comprises the PLMN but does not contain the TAC, the target cell supports NSA; when the SIB1 comprises the PLMN and the TAC, the target cell supports SA. When the SIB1 comprises the PLMN and the TAC, and the third indication information takes 1 or 0, the target cell supports SA+NSA.

[0133] In the embodiment of the application, the networking type supported by the NR cell can be determined, which is beneficial to better planning of the adjacent cell relationship of the network by the operator.

[0134] Referring to Figure 5 The embodiment of the application further provides a method for determining the networking type supported by a cell, and the execution subject of the method can be a terminal device, and the specific steps are as follows:

[0157] For example, when the third bit information takes the value 1, and / or the fourth bit information takes the value 0, it is determined that the target cell supports standalone networking.

[0158] (2) When the third bit information takes the second value, and / or the fourth bit information takes the first value, it is determined that the target cell supports non-standalone networking (NSA).

For example, when the first bit information takes the value 1, and the second bit information takes the value 1, it is determined that the target cell supports non-standalone networking and standalone networking.

[0162] (4) When the third bit information takes the second value, and the fourth bit information takes the second value, it is determined that the target cell supports a second type, wherein the system information broadcast by the cell of the second type does not contain SIB1 (or RMSI).

[0163] That is, when the third bit information takes the same value as the fourth bit information, it is determined that the target cell supports the first type. For example, when the first bit information takes the value 0, and the second bit information takes the value 0, it is determined that the target cell supports the first type, that is, the system information broadcast by the target cell does not contain SIB1.

[0164] In the embodiments of the present application, the networking type supported by the cell can be determined, which is beneficial to better planning of the adjacent cell relationship of the network by the operator.

[0165] Referring to Figure 7 , the embodiments of the present application also provide a method for determining the networking type supported by a cell, and the execution subject of the method can be a terminal device, and the specific steps are as follows:

[0166] Step 701: sending, to the network device, the related information of the SIB1 of the target cell, so as to make the network device send a connection establishment request to the target cell, and when the connection establishment of the network device and the target cell fails, determining, by the network device, that the networking type supported by the target cell is the standalone networking;

[0167] Or,

[0168] Step 702: sending, to the network device, the related information of the SIB1 of the target cell, so as to make the network device send a connection establishment request to the target cell, receiving, by the network device, a first message responding to the connection establishment request from the target cell, the first message including second indication information, the second indication information being used to indicate the type (SA, NSA or SA+NSA) of the target cell, and determining, by the network device, the networking type supported by the target cell according to the second indication information.

[0169] In the embodiment of the application, optionally, the second indication information includes third bit information and / or fourth bit information. The third bit information is used to indicate whether the target cell supports the standalone networking, and the fourth bit information is used to indicate whether the target cell supports the non-standalone networking; or the third bit information is used to indicate whether the target cell supports the non-standalone networking, and the fourth bit information is used to indicate whether the target cell supports the standalone networking.

[0170] In the embodiment of the application, (1) when the value of the third bit information is a first value, and / or the value of the fourth bit information is a second value, it indicates that the target cell supports the standalone networking (SA).

[0171] For example, when the value of the third bit information is 1, and / or the value of the fourth bit information is 0, it indicates that the target cell supports the standalone networking.

[0172] (2) when the value of the third bit information is the second value, and / or the value of the fourth bit information is the first value, it indicates that the target cell supports the non-standalone networking (NSA).

[0173] For example, when the value of the third bit information is 0, and / or the value of the fourth bit information is 1, it indicates that the target cell supports the non-standalone networking.

[0174] (3) when the value of the third bit information is the first value, and the value of the fourth bit information is the first value, it indicates that the target cell supports the non-standalone networking and the standalone networking (SA+NSA).

[0175] That is, when the value of the third bit information is the same as the value of the fourth bit information, it is determined that the target cell supports the non-standalone networking and the standalone networking.

[0176] For example, when the third bit information has a value of 1 and the fourth bit information has a value of 1, it indicates that the target cell supports non-standalone and standalone networking.

[0177] (4) When the third bit information has a value of the second value and the fourth bit information has a value of the second value, it indicates that the target cell supports the second type, wherein the system information broadcast by the cell of the second type does not include SIB1 (or RMSI).

[0178] That is, when the value of the third bit information and the value of the fourth bit information are the same, it indicates that the type of the target cell is the second type. For example, when the third bit information has a value of 0 and the fourth bit information has a value of 0, it indicates that the type of the target cell is the second type.

[0179] Examples:

[0180] The terminal device normally reports the CGI of the NR cell;

[0181] If the content reported by the terminal device does not include SIB1, the LTE base station can send an X2 interface establishment request, or the eLTE base station can send an Xn interface establishment request.

[0182] If the content reported by the terminal device includes SIB1 (for example, the content in SIB1 is complete, or the content in SIB1 is incomplete):

[0183] (1) The LTE base station can send an X2 interface establishment request, if the X2 interface establishment fails, the LTE base station determines that the type of the NR cell is SA, and no longer attempts to establish EN-DC. The NR cell can record the X2 interface establishment request of the LTE base station. If the NR cell also supports NSA function, the NR cell can actively establish the X2 interface with the LTE base station, or the system information broadcast by the NR cell does not include SIB1.

[0184] Further, if the X2 interface establishment fails, the NR cell notifies the cause value of failure of the X2 interface establishment failure, which is used to indicate that the type of the NR cell is SA.

[0185] Further, if the X2 interface establishment fails, the connection establishment request (such as X2 SETUP REQUEST) is not responded, and the type of the NR cell is notified as SA.

[0186] Further, if the X2 interface establishment fails, only the connection establishment request (such as X2 SETUP REQUEST) is not responded, that is, only the connection establishment request is ignored.

[0187] (2) The eLTE base station sends an Xn interface establishment request, and indicates the type of the NR cell as SA, NSA or SA+NSA in a response message of the Xn interface establishment request. For example, the response message can use two bits to indicate the type of the NR cell.
