Technical Field

Background

An operator will typically establish base stations along a high-speed rail (referred to as high-speed rail base stations for short) to provide services for high-speed rail users. However, when the high-speed rail passes through the residential area along the line, the coverage area of the base station (for short, residential base station) providing service for the residential area and the coverage area of the high-speed rail base station may have an overlapping area. Thus, when the high-speed rail travels to the overlapping area, the terminal used by the user of the high-speed rail may access the residential base station. Due to the fact that configuration parameters of the residential base station and the high-speed railway base station are different, user experience of high-speed railway users cannot be guaranteed.

Detailed Description

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", etc. do not limit the quantity and execution order.

The method for determining the access network device provided by the embodiment of the invention is suitable for the base station and the terminal shown in fig. 1. When a base station sends (transport, TX) information, data is transmitted through k transmission links; when the kth transmission link is used for transmitting information, the kth transmission link comprises the following steps: firstly, according to a symbol (symbol) carried in a sub-baseband (sub-baseband) k (where the symbol refers to information that a base station needs to transmit), then performing Inverse Fast Fourier Transform (IFFT) on the symbol according to a carrier spacing (sub-carrier spacing) k to obtain a signal k, and further adding (add) a cyclic redundancy Code (CP) to the signal k _k Thereafter, the CP is added by the beamforming filter (beamforming filter) pair _k Performing signal processing on the signal k to obtain a signal k after the wave beam forming is performed on the kth transmission link; and finally, performing beam integration on the signals k subjected to beam forming by each transmission link, and transmitting the signals subjected to beam integration to a signal receiving end through an antenna, thereby realizing information transmission.

When a terminal Receives (RX) a symbol carried on a subband k from a base station through an antenna, the symbol is first subjected to signal processing by a shaping filter to obtain a processed signal, then a CP of the signal is removed, then the CP-removed signal is subjected to Fast Fourier Transform (FFT) according to a carrier interval k, and then Orthogonal Frequency Division Multiplexing (OFDM) detection is performed on the subband i of the FFT-signal-processed signal, so that the symbol carried on the subband k and sent by the antenna receiving base station is converted into a signal recognizable to the terminal.

In the embodiment of the present invention, the access network device may be a base station or a base station controller for wireless communication, etc. In the embodiment of the present invention, the base station may be a base station (BTS) in a global system for mobile communications (GSM), a Code Division Multiple Access (CDMA), a base station (node B, NB) in a Wideband Code Division Multiple Access (WCDMA), an eNB in a Long Term Evolution (Long Term Evolution, LTE), an eNB in an internet of things (IoT) or a narrowband internet of things (NB-IoT), a base station in a future 5G mobile communication network or a Public Land Mobile Network (PLMN) in a future Evolution, which is not limited in any way.

Terminals are used to provide voice and/or data connectivity services to users. A terminal may have different names such as User Equipment (UE), access terminal, terminal unit, terminal station, mobile station, remote terminal, mobile device, wireless communication device, vehicular user equipment, terminal agent, or terminal device, etc. Optionally, the terminal may be various handheld devices, vehicle-mounted devices, wearable devices, and computers with communication functions, which is not limited in this embodiment of the present invention. For example, the handheld device may be a smartphone. The in-vehicle device may be an in-vehicle navigation system. The wearable device may be a smart bracelet. The computer may be a Personal Digital Assistant (PDA) computer, a tablet computer, and a laptop computer.

The method for determining access network equipment provided by the embodiment of the invention is suitable for a communication system shown in fig. 2, and the communication system comprises access network equipment 1, access network equipment 2 and a terminal 3.

Illustratively, when the access network device 1 is a high-speed rail base station, the access network device 2 is a residential base station, and the terminal 3 is in an overlapping area between a coverage area of the high-speed rail base station and a coverage area of the residential base station, the terminal 3 may determine the accessible access network device by executing the method for determining the access network device according to the embodiment of the present invention, so as to prevent the terminal of the high-speed rail user from accessing a base station that provides services for a general residential and prevent the terminal of the general residential from accessing a base station that provides services for the high-speed rail user.

In the following, referring to the communication system shown in fig. 2, taking an access network device as a base station as an example, a method for determining an access network device provided in the embodiment of the present invention is described.

As shown in fig. 3, the method for determining the base station includes the following contents of S11-S13:

and S11, the terminal acquires the current moving speed, the number of antennas of each accessible base station and the operation parameters.

In an implementation manner, the terminal may periodically (e.g., every Transmission Time Interval (TTI)) acquire real-Time location information according to a Global Positioning System (GPS) or a BeiDou navigation satellite system (BDS), and determine a current moving speed according to location information corresponding to two adjacent Time instants.

For example, taking the position information as the GPS coordinate and the sampling period as the TTI, the moving speed V is equal to

Wherein, La _i Indicating longitude information of the current TTI acquisition, La _i-1 Indicating the longitude information of the last TTI acquisition, LO _i Indicates the current TTILatitude information of the set, LO _i-1 Indicating latitude information acquired in the last TTI.

In another practical way, the base station obtains real-time location information of the terminal (the location information may be GPS coordinate information or BDS coordinate information), so that the base station determines the moving speed of the terminal according to the location information of the terminal at two adjacent time instants. And further transmitting the moving speed to the terminal, so that the terminal can determine the current moving speed.

In one implementation, the number of antennas may be the number of Transmit and Receive (TR) components. The base station side adds the identifier corresponding to the TR number into the switching or reselection signaling, so that the terminal decodes the switching or reselection signaling acquired from the base station to obtain the TR number corresponding to the base station.

For example, the table of information collected by the terminal and related to the base station is shown in table 1, where the operating parameters include Reference Signal Receiving Power (RSRP) and a load ratio.

TABLE 1

Base station (cell) identity	RSRP	Number of antennas	Rate of load
				PCI
1	RSRP1	2TR	H1
				PCI
2	RSRP2	32TR	H2
				PCI 3	RSRP3	8TR	H3

And S12, the terminal determines the access network equipment type corresponding to each base station according to the number of the antennas of each base station.

And S13, the terminal determines the accessible base stations according to the access network equipment type and the moving speed corresponding to each base station and the operation parameters of each base station.

Note that, when the base station to which the terminal has currently accessed is the accessible base station, no action is performed.

As can be seen from the above, when the terminal is located in the overlapping area between the coverage area of the base station providing service for the residential area and the coverage area of the high-speed base station, the determination method of the access network device provided by the embodiment of the present invention can determine the accessible base station according to the type of the access network device corresponding to each base station, the moving speed, and the operating parameter of each base station. Therefore, the problem of how to select the accessible base station when the terminal is located in the overlapping area of the coverage area of the residential base station and the coverage area of the high-speed base station is solved.

In an implementation manner, referring to fig. 3, as shown in fig. 4, the above S12 can be specifically realized by the following S120.

And S120, the terminal inquires a pre-stored access network equipment type table according to the number of the antennas of each base station and determines the access network equipment type corresponding to each base station. The access network equipment type table meets the corresponding relation between the number of antennas and the type of access network equipment, and the type of access network equipment comprises low-antenna-number access network equipment and high-antenna-number access network equipment.

In one practical way, since the Active Antenna Unit (AAU) of the high-Antenna-number access network device (e.g., 64TR, 32TR) uses multiple arrays, e.g., 192 arrays are used to perform complex shaping operations, it is possible to allocate a relatively independent interference-free channel to the terminal of each user. When the terminal of the user is in a high-speed motion state, the base station will increase the time for calculation when receiving the information fed back by the terminal, so that the access network equipment with high antenna number has insufficient time for calculation, and the performance is reduced. However, the access network device with a low antenna number generally uses one beam direction already fixedly, and does not need to perform shaping calculation, so that the access network device can be suitable for being used in a high-speed scene. Therefore, after the terminal identifies the access network equipment category corresponding to each base station through the number of antennas of the base station, when the terminal is in the overlapping area between the coverage area of the high-speed rail base station and the coverage area of the residential base station, the terminal can determine the access network equipment category of each accessible base station, so that the access network equipment category can be selected as the base station of the low-antenna-number access network equipment (i.e. the high-speed rail base station).

Illustratively, the access network device class table is shown in table 2.

TABLE 2

Number of TR	Access network device class	Description of the use
			2TR, 4TR and 8TR	Low antenna number access network device	For high speed scene usage
32TR、64TR	High antenna number access network device	For low speed scene usage

In another implementable manner, when the terminal determines that the number of antennas of the base station is greater than the preset number of antennas, it determines that the access network device category of the base station is the high-antenna-number access network device. Or when the terminal determines that the number of the antennas of the base station is less than or equal to the preset number of the antennas, determining that the type of the access network equipment of the base station is the low-antenna-number access network equipment.

As can be seen from the above, by storing the access network device type table in the terminal in advance, the terminal can store the access network device type table according to the number of antennas of the base station, and determine the access network device type of each base station. Further, the terminal may determine the accessible base station according to the current moving speed and the category of the access network device, or the terminal may determine the accessible base station according to the current moving speed, the category of the access network device, and the load rate.

In an implementation manner, the operation parameter includes RSRP, in which case, as shown in fig. 5 in conjunction with fig. 3, the above S13 can be specifically realized through the following S130 to S132.

S130, the terminal arranges the RSRP of each base station according to a preset arrangement sequence, and determines an access network equipment arrangement list.

For example, taking the preset arrangement order as a descending order, the ordered list of the access network devices is shown in table 3.

TABLE 3

Base station (cell) identity	RSRP
		PCI
1	RSRP1
		PCI
2	RSRP2
		PCI 3	RSRP3

Since higher RSRP of the base station indicates higher radio signal strength, the terminal preferentially considers the base station with higher RSRP when accessing the base station.

S131, under the condition that the moving speed is larger than the speed threshold, the terminal sequentially judges whether the access network equipment category of each base station in the access network equipment ranking list meets a first preset condition or not until a base station meeting the first preset condition is found. The first preset condition meets the condition that the access network equipment is low-antenna-number access network equipment.

In an achievable manner, the movement speed of the terminal is different for the resident use than for the high-speed rail user. Therefore, residents and high-speed rail users can be screened out through the speed threshold, and then the terminal can select a proper base station according to the current moving speed, so that the user experience is guaranteed.

Illustratively, taking the speed threshold as 80km/h as an example, in the case that the moving speed of the terminal is greater than 80km/h, when the access network equipment category of the base station is low-antenna-number access network equipment, the terminal accesses the base station.

S132, the terminal determines the base station meeting the first preset condition as an accessible base station.

In an implementation manner, the operation parameter further includes a load factor, in this case, as shown in fig. 6 in conjunction with fig. 3, the above S13 can be specifically realized by the following S130, S133 and S134.

In an implementation, the loading of the base station is evaluated by the base station, and the loading rate of the base station is not transmitted to the terminal. According to the method for determining the access network equipment provided by the embodiment of the invention, the identifier corresponding to the load rate of the base station is added into the switching or reselection signaling, so that the terminal determines the load rate of the base station by decoding the switching or reselection signaling acquired from the base station.

In one achievable approach, the load ratio is equal to the ratio of the radio resources currently already occupied by the base station to the total radio resources of the base station.

And S133, under the condition that the moving speed is less than or equal to the speed threshold, the terminal sequentially judges whether the access network equipment type and the load rate of each base station in the access network equipment ranking list meet a second preset condition or not until a base station meeting the second preset condition is found. Wherein the second preset condition comprises: the access network equipment type is high-antenna-number access network equipment, or the access network equipment type is low-antenna-number access network equipment, and the load rate is smaller than or equal to the preset load rate.

Illustratively, taking the speed threshold as 80km/h as an example, in the case that the moving speed of the terminal is less than or equal to 80km/h, when the access network equipment category of the base station is high-antenna-number access network equipment, the terminal accesses the base station.

And S134, the terminal determines the base station meeting the second preset condition as an accessible base station.
