Description

Method and equipment for updating neighbor cell

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for updating a neighboring cell.

Background

For an NR (New Radio, New air interface) ground communication system, a terminal in an idle state or an inactive state controls a terminal own neighbor measurement process based on system information broadcasted by a cell, each cell broadcasts basic information of its own neighbor in system information, where neighbor list information included is a main basis for the terminal to perform neighbor measurement, and the neighboring list information mainly appears in a manner of adding a physical cell identifier of the neighbor to a carrier frequency used by the neighbor, if the neighbor is an intra-frequency neighbor, corresponding intra-frequency neighbor list information is broadcasted in system information 3, if the neighbor is an inter-frequency neighbor, corresponding inter-frequency neighbor list information is broadcasted in system information 4, if the neighbor is an inter-system neighbor, corresponding inter-system neighbor list information is broadcasted in system information 5, and at this point, an organization form of an L TE (L ong Term Evolution ) system is basically used.

After the terminal acquires the necessary neighbor cell information in the resident cell, when the measurement starting condition configured in the system message is satisfied, the terminal starts the neighbor cell measurement process according to the acquired neighbor cell list information.

Because the adjacent cell of the satellite is not completely fixed relatively, if the satellite communication system still adopts the idle state or inactive state measurement scheme of the NR terrestrial communication system to select and reselect the adjacent cell, that is, the adjacent cell list information broadcasted by the cell remains unchanged, the situation that the terminal has failed to measure the adjacent cell or has missed to measure the newly-appeared adjacent cell may occur.

In summary, there is no flexible indication scheme for informing the idle or inactive terminal of the dynamic neighboring cell relationship in the satellite communication system and further efficiently controlling the mobility of the idle or inactive terminal.

In a satellite communication system, considering that surrounding adjacent cell relations are not all relatively fixed, satellites with different tracks may not be adjacent cells of a cell for a certain period of time but become adjacent cells of the cell after a period of time, mainly considering that a terminal in an idle state or an inactive state still starts measurement according to adjacent cell information broadcasted by the cell before, and possibly generating a situation that the terminal consumes a large amount of measurement energy but cannot always measure a lot of adjacent cell signals before.

The network side equipment of the embodiment of the invention can inform the idle state or the non-activated state terminal of the dynamic adjacent cell related information, thereby efficiently controlling the mobility of the idle state or the non-activated state terminal.

The terminal in fig. 1 is a specific example of the terminal of the present application. The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

As shown in fig. 1, a system for updating a neighboring cell provided in an embodiment of the present invention includes:

the network side device 10 is configured to update the neighboring cell related information broadcasted by the local cell based on the star-orbit diagram information, the frequency band mapping related information, and the physical cell identifier mapping information when a preset condition is met; and through the paging process, all terminals in the cell are instructed to acquire the updated neighbor cell related information broadcasted by the cell.

The terminal 20 is configured to receive an indication from a network side through a paging process, and determine that neighboring cell related information of a local cell broadcasted by the network side is updated; and re-receiving the updated neighbor related information broadcasted by the network side.

After the network side equipment updates the neighbor cell related information broadcasted by the cell, the network side equipment can instruct all terminals in the cell to acquire the updated neighbor cell related information broadcasted by the cell through the paging process, so that the terminals can receive the updated neighbor cell related information broadcasted by the network side again, and the terminals can measure the updated neighbor cell related information very accurately and efficiently.

The network side equipment can accurately determine the neighbor cells of the cell based on the star-orbit diagram information, the frequency band mapping related information and the physical cell identification mapping information. Optionally, the network side device is further configured to delete cell information of a non-neighboring cell of the local cell and/or increase cell information of a neighboring cell of the local cell based on the star-orbit map information, the frequency band mapping related information, and the physical cell identifier mapping information.

In practice, the cells in which satellites with different trajectories are located may be different and thus may vary for neighboring cells. And when a certain cell is no longer the adjacent cell of the cell, deleting the cell information of the certain cell in the adjacent cell list information. When a certain cell is not a neighboring cell of the cell and is now a neighboring cell of the cell, cell information of the certain cell is added to a neighboring cell list.

In this embodiment, the network side device may re-determine the neighboring cell information and broadcast the neighboring cell information when meeting a preset condition, where the preset condition may be set as needed, and the detected trajectory change is relatively large, or may be spaced by a certain time.

As an optional implementation manner, in this embodiment, the determining, by the network side device, that the preset condition is met includes: determining that a preset condition is met when the number of the cells contained in the deleted cell information of the non-adjacent cell exceeds a first preset value; and/or determining that the number of the cells included in the increased cell information of the neighboring cell exceeds a second preset value, and then determining that a preset condition is met. The first preset value and the second preset value are not limited herein, and the first preset value may be the same as the second preset value or different from the second preset value.

In a satellite communication system, the position of a satellite is not fixed and unchanged, and the satellite operates according to the operation orbit of the satellite to generate orbital operation data information of the satellite, which is used for describing the position, the orbit and the direction of the satellite in space. The satellite orbit diagram information comprises orbit operation data information of all effective satellites and satellite identification related information, wherein all the effective satellites are all effective satellites in a jurisdiction object, and the satellite identification related information is used for identifying and distinguishing the satellites.

The frequency band mapping related information comprises: mapping information associating a frequency band used by the satellite with orbital operation data information of the satellite; or mapping information associating the frequency band used by the satellite with the satellite identification related information.

The carrier frequency bands used by the satellites on different operation orbits are different, and after the mapping information which associates the frequency bands used by the satellites with the orbital operation data information of the satellites is obtained, the carrier frequency band information used by the satellites can be determined by searching the frequency band mapping related information.

Because the satellites corresponding to the same satellite identifier generally run in the fixed orbit, the running orbit information can be known by knowing the satellite identifier related information, and therefore, the carrier frequency band information used by the satellite can be determined by searching the frequency band mapping related information by obtaining the mapping information which associates the frequency band used by the satellite with the satellite identifier related information, namely the certain satellite identifier related information.

Optionally, the physical cell identifier mapping information is: mapping information associating physical cell identities used by the satellite cells with the satellite identity related information.

By obtaining information related to a certain satellite identifier, the physical cell identifier information used by the satellite can be determined by searching physical cell identifier mapping information.

L TE (L ong terminal Evolution, long Term Evolution) is a wireless signal for distinguishing different cells, and it is guaranteed that there is no same physical cell identity in the coverage of the relevant cell.

The cell refers to a cell corresponding to a physical cell identifier used by a satellite, and after carrier frequency band information used by the satellite and the physical cell identifier used by the satellite are determined, a neighbor cell of the cell can be determined and neighbor cell broadcasting can be carried out.

Optionally, the updating, by the network side device, the neighboring cell related information broadcasted by the cell includes: and updating the neighbor cell list information broadcasted by the cell, wherein the neighbor cell list information comprises deleted cell information of non-neighbor cells and/or added cell information of neighbor cells. The updated neighbor cell related information broadcast by the network side and re-received by the terminal includes the deleted cell information of the non-neighbor cell and/or the added cell information of the neighbor cell.

For an NR ground communication system, a terminal in an idle state or an inactive state controls a self adjacent cell measurement process based on system information broadcasted by cells, each cell broadcasts basic information of the self adjacent cell in the system information, the included adjacent cell list information is a main basis for the terminal to carry out adjacent cell measurement, the adjacent cell list information mainly appears in a mode of adding a carrier frequency point used by the adjacent cell and a physical cell identifier of the adjacent cell, and if the adjacent cell is the same-frequency adjacent cell, the corresponding same-frequency adjacent cell list information is broadcasted in a system message 3; if the cell is a pilot frequency adjacent cell, the corresponding pilot frequency adjacent cell list information is broadcasted in the system message 4; if the inter-system neighbor cell is the inter-system neighbor cell, the corresponding inter-system neighbor cell list information is broadcasted in the system message 5. In this embodiment, the network side device may broadcast the corresponding neighboring cell by using the system message 3, the system message 4, and the system message 5.

Optionally, when the network side device updates the neighbor cell list information broadcasted by the cell, the method further includes: and updating the public cell reselection configuration message broadcasted by the cell. The updated neighboring cell related information broadcast by the network side and re-received by the terminal further includes an updated common cell reselection configuration message.

The common cell reselection configuration information broadcasted by the cell refers to a set of common parameter information applicable to all co-frequency cells or inter-access technologies, namely the common parameter information does not depend on a certain cell.

If the public cell reselection configuration information broadcasted by the cell changes, the neighbor cell list information broadcasted by the cell needs to be updated and the public cell reselection configuration information broadcasted by the cell needs to be updated at the same time.

Optionally, the network side device instructs, through the paging process, all terminals in the local cell to obtain updated neighboring cell related information broadcasted by the local cell, and the method may be implemented in any two ways:

the first method is as follows:

and the network side equipment indicates that the neighbor cell related information broadcasted by the cell is updated through the newly defined bit in the paging message. And the terminal determines that the neighbor cell related information of the cell broadcasted by the network side is updated through the newly defined bit in the paging message.

NR paging content setting includes both paging message content setting and paging control channel content setting.

The paging message content setting comprises contents of two aspects, wherein the first part is a paging record and is used for filling terminal identification list information needing paging at the paging moment; the second part is a one-bit access category indication information for indicating whether the current paging message is from a non-3 GPP (3rd Generation Partnership Project) system.

Optionally, the newly defined bit in the paging message is a newly added bit in the paging message.

Here, a new IE (Information Element) is defined in the existing paging message, and occupies a bit, and the new IE is used to indicate that the neighboring cell related Information broadcasted by the terminal local cell is updated.

In implementation, the network side device indicates, through the paging message including the information unit for indicating that the neighboring cell related information broadcasted by the terminal itself is updated, that the neighboring cell related information broadcasted by the terminal itself is updated. The terminal receives the indication of the network side through the paging message, and determines that the neighbor cell related information of the cell broadcasted by the network side is updated.

The second method comprises the following steps:

and the network side equipment indicates the updating of the neighboring cell related information broadcasted by the cell through the newly defined bit in the paging short message. And the terminal determines that the neighbor cell related information of the cell broadcasted by the network side is updated through the newly defined bit in the paging short message.

The NR paging control channel content setting comprises three parts, the first part comprises two bits of indication information for indicating the presence or absence of the remaining two parts of content, the specific rule is shown in table 1.

TABLE 1

Bit dereferencing	Meaning of bit value
		00	Reservation
01	Only paging scheduling information
		10	Only paging short messages
11	Simultaneously contains paging scheduling information and paging short message

The second part comprises paging scheduling information used for indicating the resource position of the paging short message; the third part contains paging short message, NR system defines 8 bit paging short message in physical downlink control channel, and the existing format of 8 bit is shown in Table 2.

TABLE 2

One of the bits is used for indicating system information updating, the other bit is used for indicating alarm information updating, and the remaining 6 bits are temporarily reserved without use.

Optionally, the newly defined bit in the paging short message is a reserved bit in the paging short message.

Redefining one bit in the reserved bit of the paging short message to indicate updating of the neighbor related information, wherein the format after the neighbor related information updating indication information is added is shown in table 3.

TABLE 3

In implementation, the network side device indicates, by using the paging short message for indicating that the neighboring cell related information broadcasted by the terminal local cell is updated, that the neighboring cell related information broadcasted by the terminal local cell is updated. The terminal receives the indication of the network side through the paging short message, and determines that the neighbor cell related information of the cell broadcasted by the network side is updated.

The terminal receives the indication of the network side through any one paging process, and determines that the neighbor cell related information of the cell broadcasted by the network side is updated; and re-reading the system information and re-receiving updated neighbor cell related information broadcasted by the network side according to the scheduling information in the system information.

Optionally, if the terminal determines that the neighboring cell related information of the cell broadcasted by the network side is updated, the terminal re-reads the scheduling information in the system information 1; and acquiring and updating the adjacent cell related information broadcasted by the cell according to the scheduling information.

The paging message/paging short message sent by the network side equipment can only indicate that the neighbor cell related information of the cell broadcasted by the network side of the terminal is updated, and cannot indicate how the terminal receives the updated neighbor cell related information broadcasted by the network side again. And the updated neighbor related information indicating that the terminal re-accepts the network side broadcast is in the system information 1. Therefore, when the terminal receives the paging message sent by the network side, if the indication bit in the paging message indicating that the neighbor related information broadcasted by the cell is updated is set to be valid, the terminal needs to read the system information 1 again, and re-receive the neighbor related information broadcasted by the cell from the system information 3, the system information 4 and the system information 5 according to the scheduling information in the system information 1.

Optionally, when the terminal obtains the updated neighboring cell related information broadcasted by the local cell, the terminal performs idle or inactive mobility detection using the updated neighboring cell related information broadcasted by the local cell.

Before the terminal acquires the updated neighbor cell related information broadcasted by the cell, the terminal still uses the previously stored and effective neighbor cell related information broadcasted by the cell to carry out idle or inactive mobility measurement.

After the terminal acquires the necessary neighbor cell related information in the resident cell, when the measurement starting condition configured in the system message is satisfied, the terminal starts the neighbor cell measurement process according to the acquired neighbor cell list information.
