Description

Information query method, user equipment, server and storage medium

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to an information query method, user equipment, a server and a storage medium.

Background

In order to optimize Network services along a High-Speed railway/highway, related information about a High Speed Dedicated Network (HSDN) cell is added to system information broadcast by a base station, so as to indicate whether a cell where User Equipment (UE) resides and an adjacent cell near the cell are HSDN cells.

Currently, when the UE cannot decode the relevant information about the HSDN cell in the system information broadcast by the base station, the UE may interrupt communication. Specifically, in a scenario, in a state where the UE is moving at a high speed, since the UE cannot decode related information about the HSDN cell, the UE may enter a non-HSDN cell (e.g., cell 1), and after the UE enters cell 1, the UE may rapidly leave cell 1 again, and at this time, if the UE does not search for a cell to be handed over (HSDN cell or non-HSDN cell), the UE cannot successfully hand over the cell, thereby causing communication interruption of the UE. In another scenario, in a state where the UE is moving at a non-high speed, since the UE cannot decode the relevant information about the HSDN cell, the UE may enter one HSDN cell (e.g., cell 2), and if the UE leaves cell 2 while in a connected state, the UE cannot successfully handover to the HSDN cell when the UE does not search for the HSDN cell to be handed over, thereby causing a communication interruption of the UE.

Therefore, when the UE performs cell handover along the highway/highway, the communication of the UE may be interrupted.

In the prior art, when the UE cannot decode the relevant information about the HSDN cell in the system information broadcast by the base station, the UE may cause the communication interruption of the UE when performing cell handover along the highway/highway.

In order to solve the problem, embodiments of the present invention provide an information query method, user equipment, a server, and a storage medium. Firstly, UE sends query information to a first server, wherein the query information is used for the first server to query whether a target cell is an HSDN cell; then, after receiving the query information sent by the UE, the first server sends query result information to the UE, where the query result information is used to indicate whether the target cell is an HSDN cell. The query information includes a cell identifier of a first cell or system information of the first cell, the first cell is a cell where the UE currently resides, the target cell includes the first cell and N second cells, the N second cells are neighboring cells of the first cell, and N is a positive integer. Therefore, the UE can query whether the first cell is an HSDN cell and whether an adjacent cell of the first cell is an HSDN cell in the first server according to the cell identifier of the first cell or the system information of the first cell, and can determine how and to which cell the UE is switched according to the queried result information when the UE switches the cells in an idle state, thereby avoiding communication interruption caused by cell switching failure when the UE switches the cells under the condition that whether the target cell is the HSDN cell cannot be determined, and further improving the communication service quality when the UE moves along a high-speed railway/highway.

Fig. 1 is a diagram of a possible architecture of a query system according to an embodiment of the present invention, as shown in fig. 1, the query system includes a UE10 and a first server 11. Wherein, a wireless link may be established between the UE10 and the first server 11, and the UE10 and the first server 11 may transmit information to each other through the established wireless link.

The UE may be a wireless terminal device, which may be a device providing voice and/or other service data connectivity to a user, a handheld device with wireless communication functionality, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN network, and so on. A Wireless terminal device may communicate with one or more core networks via a Radio Access Network (RAN), and may be a Mobile terminal, such as a Mobile phone (or "cellular" phone) and a computer with a Mobile terminal, for example, a portable, pocket, hand-held, computer-embedded or vehicle-mounted Mobile device, which exchanges languages and/or data with the RAN, and Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like, and may also be a Mobile device, a UE terminal, an Access terminal, a Wireless Communication device, a terminal unit, a terminal Station, a Mobile Station (Mobile Station), a Mobile terminal, a Wireless Communication system, and a Wireless Communication system, A Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Station, a Remote Terminal (Remote Terminal), a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a User Agent (User Agent), a Terminal device, and the like. As an example, in the embodiment of the present invention, fig. 1 illustrates that the UE is a mobile phone.

For convenience of description, in the following embodiments, a UE queries whether a target cell is an HSDN cell through a first server, and both the first server and a second server described below may execute the information querying method provided in the embodiments of the present invention, where the first server and the second server may be the same server or different servers, and this is not specifically limited in the embodiments of the present invention.

The information query method according to the embodiment of the present invention is described below with reference to fig. 2. Fig. 2 is a schematic flow chart of an information query method according to an embodiment of the present invention, and as shown in fig. 2, the information query method includes steps S201 to S204:

s201, the UE sends inquiry information to a first server.

The query information includes a cell identifier of a first cell or system information of the first cell, the first cell is a cell where the UE currently resides, the query information is used for a first server to query whether a target cell is an HSDN cell, the target cell includes the first cell and N second cells, the N second cells are neighboring cells of the first cell, and N is a positive integer.

Optionally, the first cell may be a cell in a Long Term Evolution (LTE) System, a cell in a Global System for Mobile communication (GSM) System, a cell in a Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access) System, a cell in a Wideband Code Division Multiple Access (WCDMA), or the like, or may also be a cell in another communication System, which is not specifically limited in the embodiment of the present invention.

It is to be understood that the first server may be a server having a function of inquiring whether a cell is an HSDN cell. For example, the first server may be a server having a function of decoding system information, the first server may also be a server that stores whether the cell is the data of the HSDN cell at the cloud, and the first server may also be a server that has both a function of decoding system information and stores whether the cell is the data of the HSDN cell.

Generally, the UE may select one camping Cell through Cell Selection (Cell Selection) in an Idle Mode.

S202, the first server receives the inquiry information sent by the UE.

S203, the first server sends the query result information to the UE.

And the query result information is used for indicating whether the target cell is the HSDN cell.

S204, the UE receives the query result information sent by the first server.

It can be understood that, after the UE determines whether the target cell is an HSDN cell according to the query result information sent by the first server, the UE may measure the signal strength of the target cell, and then the UE determines whether to perform cell reselection and selects which cell to serve as a new camping cell according to the signal strength of each cell in the target cell and whether the target cell is an HSDN cell.

Generally, if the UE is in a High Mobility State (High Mobility State), when the UE performs Cell Reselection (Cell Reselection), the UE sets the priority of the HSDN Cell as the highest priority, and preferentially selects the HSDN Cell; if the UE is in a non-high-speed moving state, when the UE performs cell reselection, the UE sets the priority of the HSDN cell as the lowest priority, and the UE avoids selecting the HSDN cell. If the cell 1 is an HSDN cell, the system information of the cell 1 broadcasted by the base station may carry a cell equivalent size of the HSDN cell, and when the UE calculates the mobility state of the UE, the number of reselections is calculated by using the cell equivalent size value in the system information.

Firstly, UE sends query information to a first server, wherein the query information is used for the first server to query whether a target cell is an HSDN cell; then, after receiving the query information sent by the UE, the first server sends query result information to the UE, where the query result information is used to indicate whether the target cell is an HSDN cell. The query information includes a cell identifier of a first cell or system information of the first cell, the first cell is a cell where the UE currently resides, the target cell includes the first cell and N second cells, the N second cells are neighboring cells of the first cell, and N is a positive integer. Therefore, the UE can query whether the first cell is an HSDN cell and whether an adjacent cell of the first cell is an HSDN cell in the first server according to the cell identifier of the first cell or the system information of the first cell, and can determine how and to which cell the UE is switched according to the queried result information when the UE switches the cells in an idle state, thereby avoiding communication interruption caused by cell switching failure when the UE switches the cells under the condition that whether the target cell is the HSDN cell cannot be determined, and further improving the communication service quality when the UE moves along a high-speed railway/highway.

A possible implementation manner, before the foregoing S203, the information query method provided in the embodiment of the present invention may further include S205:

s205, the first server acquires first target information according to the query information.

For convenience of explanation, two forms of whether the first server may store the HSDN cell are described below as examples. In practical applications, different storage modes can be set according to needs, and other related information and the like can also be stored in the first server.

In the following, only by taking whether the cell stored in the first server is an HSDN cell or not as an example, the first server may store whether the cell is an HSDN cell according to the following a manner or B manner.

Mode A: the cell identity corresponds to which of the cell and its neighbor cells are HSDN cells and which are not HSDN cells.

For example: table 1 shows an example of a HSDN cell storage scheme a. Here, it is described by taking an example that neighboring cells of one cell include 3 cells.

TABLE 1

Of course, in table 1, only the cell that is the HSDN cell may be stored, and only the HSDN cell may be stored in the neighboring cell of the HSDN cell, which is not specifically limited in this embodiment of the present invention.

Mode B: the system information of a cell corresponds to which of the cell and its neighbor cells are HSDN cells.

For example: table 2 shows an example of a HSDN cell storage pattern B.

TABLE 2

System information	Cell identity	HSDN cells indicated in system information
			System information 1	Cell 1	Cell 1, cell 2, cell 3
System information 2	Cell 2	Cell 2, cell 1, cell 4
			System information 3	Cell 3	Cell 3, cell 1, cell 5

It should be noted that only the cell that is HSDN and the neighbor cell may be indicated in the system information.

Certainly, in practical application, the information may also be stored in other manners, and the first server may also store other information in the system information, for example, the first server also stores an indication that the cell is not an HSDN cell, and is not a quasi-HSDN cell, which is not specifically limited in the embodiment of the present invention.

Optionally, in the information query method provided in the embodiment of the present invention, S205 may be specifically implemented by the following mode 1 and mode 2.

Mode 1: the query information includes system information of the first cell, the system information of the first cell includes third target information, and S205 may be performed by S205 a:

s205a, the first server decodes the third target information to obtain the first target information.

Of course, the first server may decode the system information of the first cell to obtain the first target information.

Optionally, the third target information may be information of decoding failure of the UE in the system information of the first cell, and after the first server decodes the third target information, if the first server does not have the relevant information of the first cell, the first server may store the relevant information of the first cell in the first server, so that when querying whether the target cell is an HSDN cell, other UEs do not decode the third target information.

Based on the scheme, the first server may obtain the first target information by decoding the system information of the first cell or third target information in the system information of the first cell.

Mode 2: the query information includes a cell identifier of the first cell or system information of the first cell, and the system information of the first cell includes a cell identifier of the first cell, and the above S205 may be performed by S205 b:

s205b, the first server queries the information stored by the first server according to the cell identifier of the first cell to obtain the first target information.

Alternatively, the mode 2 may be executed by the above-described S205b, or may be executed by the mode 3 described below.

Mode 3: in the embodiment of the present invention, the above S205b may be executed through S205 c:

s205c, if the second condition is satisfied, the first server obtains the first target information, where the first target information includes the backhaul indication information.

The second condition satisfies any one of the following conditions: the fourth target information is not stored, the first cell is inquired to be a quasi HSDN cell, and the target number is smaller than or equal to the first threshold value.

The fourth target information is used to indicate that the first cell is an HSDN cell or that the first cell is a quasi-HSDN cell, the target number is the number of target switching signaling received by the first server and sent by the UE, and the target switching signaling is used to indicate that the UE is switched from the first cell to the third cell.

It should be noted that the target handover signaling received by the first server may be a handover signaling sent by different UEs, or may also be a handover signaling sent by the same UE, which is not specifically limited in this embodiment of the present invention.

It should be noted that, after the first server determines that the first cell is a quasi-HSDN cell, the first server may need to update the related information of the first cell or verify the accuracy of the related information of the first cell, and after sending the backhaul indication information to the UE, the UE may start a backhaul mechanism, and after receiving the related information of the first cell, the UE may send information indicating whether the first cell is HSDN information to the first server or to a second server associated with the first server.

Further, after S205, S203 in the above embodiment may be performed by S203a, and S204 in the above embodiment may be performed by S204 a:

s203a, the first server sends the first target information to the UE.

S204a, the UE receives the first target information sent by the first server.

Specifically, the first target information is any one of the following (1) to (10):

(1) first HSDN information

Wherein the first HSDN information includes first sub-information and third sub-information.

The first sub-information is used for indicating that the first cell is an HSDN cell, the third sub-information is used for indicating that M second cells are HSDN cells, and M is more than or equal to 0 and less than or equal to N.

That is, the first server queries that the first cell is an HSDN cell and the M second cells are HSDN cells.

It is to be understood that when M ═ 0, none of the N neighbor cells of the first cell are HSDN cells.

If the first server only queries the first HSDN information by decoding the system information of the first cell, the system information of the first cell carries information that the first cell is an HSDN cell and information that the M second cells are HSDN cells.

If the first server obtains the first HSDN information through system information query, the first cell is a HSDN cell and the M second cells are HSDN cells, which are stored in the first server corresponding to the system information of the first cell.

If the first server obtains the first HSDN information by querying through the cell identifier in the system information of the first cell, the first server stores the information that the first cell is an HSDN cell and the M second cells are HSDN cells. The system information of the first cell may carry information that the first cell is an HSDN cell and information that the M second cells are HSDN cells, or may not carry information that the first cell is an HSDN cell and information that the M second cells are HSDN cells, or may carry partial information of information that the first cell is an HSDN cell and information that the M second cells are HSDN cells, which is not specifically limited in the embodiment of the present invention.

(2) Second HSDN information

Wherein the second HSDN information includes first sub information and fourth sub information. The fourth sub-information is used for indicating that K second cells are quasi HSDN cells, and K is more than or equal to 0 and less than or equal to N.

That is, the first server queries that the first cell is an HSDN cell and the K second cells are quasi-HSDN cells.

It is to be understood that when K is 0, none of the N neighbor cells of the first cell is a quasi-HSDN cell.

It should be noted that, in the embodiment of the present invention, the system information broadcast of the quasi-HSDN cell does not carry information whether the cell is the HSDN cell, the quasi-HSDN cell has the service capability of the HSDN cell, and when the UE determines that one cell is the quasi-HSDN cell, the priority of the quasi-HSDN cell may also be set to a higher priority, so that the UE may preferentially select the HSDN cell or the quasi-HSDN cell during cell switching.

(3) Third HSDN information

Wherein the third HSDN information includes first sub information and fifth sub information. The fifth sub-information is used to indicate that the P second cells are HSDN cells and the W second cells are quasi-HSDN cells, 0< P < N, 0< W < N, and 0< P + W < N.

That is, the first server queries that the first cell is an HSDN cell, P second cells are HSDN cells, and W second cells are quasi-HSDN cells.

(4) Fourth HSDN information

Wherein the fourth HSDN includes the second sub information and the third sub information. The second sub-information is used to indicate that the first cell is a quasi-HSDN cell.

That is, the first server queries that the first cell is a quasi-HSDN cell, and the M second cells are HSDN cells.

(5) Fifth HSDN information

Wherein the fifth HSDN information includes second sub information and fourth sub information.

That is, the first server queries that the first cell is a quasi-HSDN cell and the K second cells are quasi-HSDN cells.

(6) Sixth HSDN information.

Wherein the sixth HSDN information includes second sub information and fifth sub information.

That is, the first server queries that the first cell is a quasi-HSDN cell, P second cells are HSDN cells, and W second cells are quasi-HSDN cells.

(7) And returning indication information.

The backhaul indication information is used for indicating the UE to send indication information indicating whether the first cell is an HSDN cell to the first server or a second server associated with the first server.

That is, the first server does not have information that the first cell is an HSDN cell, does not have information that the first cell is a quasi-HSDN cell, does not have information that the second cell is an HSDN cell, and does not have information that the second cell is a quasi-HSDN cell.

It should be noted that, if the first server does not store the above information, the first server instructs the UE to upload the system information, and at this time, the UE does not perform cell handover temporarily, or does not consider handover to the target cell first. If the system information does not carry information indicating whether the target cell is the HSDN cell, the first cell is a non-HSDN cell, and the UE sets the priority of the first cell to be the lowest during cell switching. And if the system information does not carry information indicating whether the target cell is the HSDN cell, the first server sends the information indicating whether the target cell is the HSDN cell in the system information to the UE, and stores the information in the first server. At this time, if the UE determines whether the target cell is the HSDN cell, the UE sets the priority of the first cell to be the highest during cell handover.

(8) Fourth HSDN information and backhaul indication information

(9) Fifth HSDN information and backhaul indication information

(10) Sixth HSDN information and backhaul indication information

Based on the scheme, when the server queries any one of the first target information, the queried first target information can be sent to the UE, so that the UE can determine which of the target cells are HSDN cells and which are quasi-HSDN cells, thereby providing a selection basis for the UE to perform cell switching, and avoiding UE communication interruption caused by switching failure due to the fact that the UE cannot determine whether the target cell is the HSDN cell.

A possible implementation manner, after S204a, the information query method provided in the embodiment of the present invention further includes S206 or S207:

s206, under the condition that the first target information comprises the backhaul indication information, the UE sends the system information of the first cell to the second server.

It should be noted that, if the system information of the first cell indicates that the first cell is an HSDN cell and that, of neighboring cells of the first cell, the neighboring cell of the HSDN cell is a neighboring cell of the HSDN cell, the second server may determine, according to the system information of the first cell, that the first cell is an HSDN cell and that, of neighboring cells of the first cell, the neighboring cell is a cell of the HSDN cell. If the second server and the first server are the same server, the second server stores the decoded information in the second server, and if the second server and the first server are different servers, the second server can send the decoded information to the first server, so that other UE can inquire whether the target cell is the HSDN cell from the first server.

Fig. 3 is a schematic diagram of a possible query system architecture according to an embodiment of the present invention, as shown in fig. 3, the schematic diagram of the query system architecture includes a UE10, a first server 11, and a second server 12. The UE10 may establish a wireless communication connection with the first server 11, and the UE may also establish a communication connection with the second server 12.

It should be noted that, in the case that the first server and the second server are two different servers, a communication connection may be established between the first server and the second server to transmit data.

S207, when the first target information includes the backhaul indication information and the first cell is the HSDN cell, the UE sends the first handover signaling received by the UE to the second server.

Wherein the first handover signaling is used to instruct the UE to handover from the first cell to the third cell.

It should be noted that, if the second server and the first server are the same server, in S207, the UE sends the first switching signaling received by the UE to the first server; if the second server and the first server are the same server, after the first handover signaling sent by the UE is received by the second server, the second server may also send the first handover signaling to the first server, which is not specifically limited in this embodiment of the present invention.

It should be noted that the third cell may be a neighboring cell of any one of the first cells.

Generally, the handover signaling is a handover signaling sent by a network side device to a UE; when the UE sends data, the UE is in a connected state. The handover information may indicate that the UE is handed over to the third cell while in the connected state.

It should be noted that, in the case that the first cell is an HSDN cell, the handover signaling sent by the network side may instruct the UE to handover from the first cell to a third cell that is the HSDN cell.

Based on the scheme, under the condition that the first target information received by the UE includes the backhaul indication information, the UE may send system information of the first cell and the first handover signaling received by the UE to the second server, so that the second server may switch from the first cell to the third cell according to the handover paths indicated in the received certain number of handover signaling, and the system information of the third cell does not indicate that the third cell is the HSDN cell, and the third cell may be the HSDN cell, and the second server may determine the HSDN cell as the quasi-HSDN cell.

In a possible implementation manner, before the foregoing S201, the information query method provided in the embodiment of the present invention may further include S208:

s208, the UE determines that a first condition is met.

The first condition includes any one of: the second target information is not stored in the UE; the second target information is not stored in the UE, and the system information of the first cell comprises information of UE decoding failure.

The second target information is used for indicating that the first cell is an HSDN cell or a quasi-HSDN cell.

It should be noted that, if the version of the UE is low, when the UE receives the system information of the first cell, the UE may not successfully decode all the system information, and if only part of the system information is decoded, the UE may not determine which cells in the neighboring cells of the camped cell and the camped cell are HSDN cells, and communication may be interrupted during cell switching.

Based on the scheme, the UE may send query information to the first server when it is determined that the UE does not store the second target information, or the UE does not store the second target information, and the system information of the first cell includes information that the UE fails to decode, so that whether the target cell is the HSDN cell may be queried through the first server.

In a possible implementation manner, the information query method provided in the embodiment of the present invention further includes S209:

s209, if the number of the target switching signaling received by the first server in the target time period is greater than or equal to a second threshold, the first server determines that the third cell is a quasi-HSDN cell.

For example, if the target time period is one month, assuming that the current time is 12 months and 5 days in 2018, the target time period may be 11 months and 5 days in 2018 to 12 months and 5 days in 2018, and the target time period may be 11 months and 1 day in 2018 to 11 months and 30 days in 2018.

It should be noted that, when the number of the target handover signaling received in the first server is greater than or equal to the third threshold, if the UE continues to upload the target handover signaling, the first server may send, to the UE, a message indicating that the UE stops backhaul. And after receiving the information of stopping postback transmission, the UE does not postback the information about whether the first cell is the HSDN cell. Of course, after the UE leaves the first cell, the UE may also stop returning the information whether the first cell is the HSDN cell.

Based on the scheme, the first server may determine whether the third cell is the quasi-HSDN cell according to the number of target handover signaling received by the first server in the target time period, and if all target handover signaling exceeding the second threshold in the target handover signaling returned by the UE is handed over from the first cell to the third cell, and the first cell is the HSDN cell, the third cell may be the HSDN cell, and the third cell is determined to be the quasi-HSDN cell.
