An exemplary embodiment of the present disclosure provides a method for accessing a cell, which may be implemented by a base station and a first terminal of each cell together, where a system framework diagram is shown in fig. 1. The base station may be a base station in a wireless communication system, for example, an evolved Node B (eNB or e-NodeB) in LTE. The first Terminal may be any Terminal in a cell, and may also be referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), and the like, for example, the first Terminal may be a Mobile phone (or a cellular phone), and the like, for example, the first Terminal may also be a portable, pocket, hand-held, computer-included, or vehicle-mounted Mobile device, and they exchange languages and/or data with a radio access network.

The transceiver may be configured to perform data transmission with a terminal or other devices, for example, send a first message carrying application class priority information corresponding to a cell to a terminal in the cell, and the transceiver may include an antenna, a matching circuit, a modem, and the like.

The first terminal may include a processor, memory, transceiver, etc. The processor may be a CPU, and the like, and may be configured to determine a first application category corresponding to the processor, determine a target cell suitable for serving the first application category, and further access related processing of the target cell. The memory may be RAM, Flash, or the like, and may be used to store received data, data required by the processing procedure, data generated in the processing procedure, or the like, such as application category priority information corresponding to each cell. The transceiver may be configured to perform data transmission with other devices, for example, receive a first message carrying application class priority information sent by a base station, and the first message may include an antenna, a matching circuit, a modem, and the like.

The process flow shown in fig. 2 will be described in detail below with reference to the embodiments, and the contents may be as follows:

in step 201, the base station determines application class priority information corresponding to the cell, where the application class priority information is used to indicate service priorities of application classes suitable for serving the cell.

The base station may be any base station in a wireless communication system, and the cell may be all cells corresponding to the base station or any cell in all cells corresponding to the base station. Each application category may be an application category having different requirements for quality of service, or an application category having different Communication attributes, that is, an application category requiring different wireless transmission parameters, for example, each application category may be eMMB (enhanced Mobile bandwidth enhancement), URLLC (Ultra-Reliable and Low Latency Communication), mtc (massive Machine-Type Communication). In addition, other application categories may be included, for example, a real-time interactive application category may be included, which may be an application category established for a conventional real-time interactive service such as a voice and video call, and may be denoted by VV.

In an implementation, the base station may store application category priority information of each corresponding cell in advance, where the application category priority information may be an application category priority list in which service priorities are ranked from high to low, and may be used to indicate service priorities of application categories suitable for being served by the cell. Specifically, the base station may respectively determine each application type as C1, C2, …, and CN, where N is the total number of application types and is a positive integer. The application class priority list for each cell may be written as: l ═ P1, P2, PM, where M is a positive integer less than or equal to N, and each element in the list can take on the value from { C, C2, …, CN }. The P1 is the application category with the highest priority assigned by the operator to the cell, the P2 is the application category with the highest priority assigned by the cell, the PM is the application category with the highest priority assigned by the cell, and when M is less than N, the application categories which are not in the application category priority list are assigned with the same lowest priority by default. A high priority indicates a high priority or other network administrator configures the cell to be more suitable for serving the application category, and a low priority indicates that the cell is configured to be relatively unsuitable for serving the application category, wherein the high priority/low and suitable/unsuitable are relative, a cell may still have the capability of serving a low priority application category, and whether it is suitable for serving a certain application category is related to radio transmission parameter configuration, service capability configuration, operation policy, etc. of the cell. When configuring the application category priority list of each cell, determining the application category priority list, and then adjusting parameters of the cell according to the application category priority list, so that the cell can preferentially serve each application category in the application category priority list; alternatively, the priority list corresponding to the cell may be determined according to the current service capability configuration of the cell.

For example, if a cell is expected to preferentially serve URLLC applications with strict delay requirements, P1 may be set to be URLLC applications, i.e., L ═ URLLC, and a shorter slot length may be configured for the cell, which indicates that other application classes correspond to the same lowest priority. For another example, if a cell has a higher carrier aggregation capability or a localized server is configured, and such a configuration is more suitable for serving an eMMB application that requires a large bandwidth and a high rate, but a large random access resource is not configured, P1 may be set to be the eMMB application, and P3 may be set to be the eMTC application, that is, L { eMMB, URLLC, eMTC }. For example, if a cell is configured with a relatively short slot length and a relatively large random access resource, P1 may be set for URLLC application and P2 may be set for eMTC, i.e., L ═ URLLC, eMTC }. For example, if a certain cell is installed in a large place such as a gym and it is desired to satisfy the conventional voice and video call applications of the population in the stadium preferentially, P1 may be set as the VV application. Note that the application requirements of other application categories may be served by cells of other frequency points or frequency bands deployed in the same geographic location in a priority manner, and the configuration of the application category priority information may be flexibly set by an operator according to actual conditions.

After configuring the corresponding application category priority information for each cell, in some cases, the base station may determine the application category priority information of the cell corresponding to the base station.

In step 202, the base station sends a first message carrying application category priority information corresponding to the cell to the terminal in the cell.

In implementation, for each cell, after determining the application class priority information corresponding to the cell, the base station may send a first message carrying the application class priority information corresponding to the cell to a terminal in the cell. The form of the application class priority information transmitted from the base station to the terminal may be various, and the application class priority information may be expressed in a text format, for example, L ═ URLLC, eMTC, eMMB }. Some index may be used for the representation, for example, when N is 3 and M is 2, eMMB may be represented by 00, URLLC may be represented by 01, and eMTC may be represented by 10. Coded representation may also be used, for example, when N ═ M ═ 3, 3 bits may be used to represent various possible permutations of three application classes embb, URLLC, eMTC, e.g., with 000L ═ { embb, URLLC, eMTC }, with 001L ═ { URLLC, embb, eMTC }, etc.

Optionally, the first message for sending the application category priority information may be a broadcast message of the cell, a system message of the cell, or an RRC (Radio Resource Control) signaling. When transmitting in a Master Information Block (Master Information Block) of a broadcast message, in order to reduce resource occupation of the MIB, the application class priority Information may preferably be represented in an indexing or encoding manner, and when transmitting in a System Information Block (SIB) or in RRC signaling, the application class priority Information may preferably be represented in a text manner.

Optionally, the base station may send, in addition to the application category priority information corresponding to a certain cell, other indication information related to the application category (which may be referred to as application category indication information, where the application category indication information may be an application category indication list) to the terminal. Correspondingly, the base station may further send, to the terminal in the cell, a second message carrying the application category indication information corresponding to the cell, where other cells corresponding to each application category in the application category indication information may be other cells that can preferentially serve the application category, or other cells that can preferentially serve the application category (other cells may be neighboring cells of the cell). The first message may or may not be the same as the second message.

The application category indication information may include a correspondence between each application category and an identifier of another cell that preferentially serves the application category, where the another cell may be a neighboring cell of the current cell, each application category may correspond to an identifier of one or more another cells, and the identifiers of the another cells in the application category indication information may be frequency points or frequency bands where the corresponding cells are located, or other identifiers, for example, physical cell identifiers. For example, for an application class Cn, the application class is served in advance by a Frequency point or a cell on a Frequency band F according to the requirement or configuration of an operator, then the application class indication information corresponding to Cn may be represented by a binary group Ik ═ Cn, F >, when F is a Frequency point, a Frequency point Number may be used, for example, EARFCN (E-UTRAAbsolute Radio Frequency Channel Number), and when F is a Frequency band, a Frequency band Number may be used. According to the above example, assuming that the application category of the local cell priority service is Cm, the base station of the local cell may further send application category indication information T ═ Ik ═ Cn, F > }onthe basis of sending application category priority information L ═ { P1 ═ Cm }. The second message may be a system message, a broadcast message or RRC signaling, that is, the base station may also send application category indication information to the terminal through the broadcast message or the system message or RRC signaling of the cell, where the application category indication information may be represented in a text form. That is, the base station may store the application type priority information of each cell in advance, or may obtain the application type priority information of other cells through communication, in this case, when determining the application type priority information of a cell, the base station may further determine the application type indication information corresponding to the cell, where the application type indication information may be an application type indication list T ═ { I1, I2, …, IK }, where K is the number of application types included in the application type indication information corresponding to the cell.

In step 203, the first terminal receives a first message carrying application class priority information sent by the base station of each cell, where the application class priority information is used to indicate a service priority of each application class suitable for service of the corresponding cell.

The first terminal may be any terminal, and may be any terminal in the terminals described in step 202.

In implementation, the first terminal may receive a first message carrying application class priority information sent by a base station of each cell (each neighboring cell), where the application class priority information may be used to indicate a service priority of each application class that is suitable for serving by a corresponding cell.

In step 204, when the first terminal selects a cell to be accessed, the first terminal determines a first application category corresponding to the first terminal.

In implementation, in an operation process, before accessing a cell, a first terminal may determine the cell to be accessed, that is, may determine an application class (which may be referred to as a first application class) corresponding to itself. Specifically, for a specific type of terminal, for example, an eMMB terminal (mobile phone, network card, etc.), a URLLC (automobile, etc.), and an mtc (machine type terminal, etc.), corresponding type parameters may be stored in advance in the terminal, where the type parameters may correspond to the application types C1, C2, …, and CN, or may correspond to a predetermined correspondence relationship. If the first terminal is a terminal of a specific type, when a cell to be accessed is selected, the first application category corresponding to the first terminal can be determined according to the prestored type parameters. For a composite terminal, for example, a terminal (such as an automobile) that can run an eMMB-type application and a URLLC-type application may determine a current corresponding application type according to an application that the terminal currently desires to launch. If the first terminal is a composite terminal, when a cell to be accessed is selected, the currently corresponding first application category may be determined according to the application which the first terminal wishes to initiate currently.

In step 205, the first terminal determines a target cell suitable for serving the first application type according to the application type priority information corresponding to each cell.

In implementation, when the first terminal selects a cell to be accessed, the first terminal may read application category priority information corresponding to each cell. After determining the first application category corresponding to the first terminal, the first terminal may determine, according to the application category priority information corresponding to each cell, whether the cell is a cell that preferentially services the first application category, where, for a case where the base station further sends a second message carrying application category indication information corresponding to the cell, the first terminal may further determine whether there are other cells that can preferentially service the first application category. The first terminal can synthesize the application category priority information and the application category indication information corresponding to the cell, and judge whether to access a certain cell or try other cells by changing frequency points or frequency bands. The decision criteria may be varied, for example, if the first application category is the highest priority of a cell, the cell may be determined to be a target cell suitable for serving the first application category. For another example, if the first application category is in the application category priority information of a cell, the cell may be determined to be a target cell suitable for serving the first application category. For another example, although the first application category is in the application category priority information of a certain cell, the service priority is not the highest, and the first terminal may determine from the application category indication information that another cell may preferentially serve the first application category, and the first terminal may re-search for a cell based on frequency points or frequency bands of another cell, and determine a target cell suitable for serving the first application category.

Optionally, the specific process of determining the target cell may be as follows: determining a preset number of application categories with highest priority corresponding to a first cell according to the application category priority information corresponding to the first cell in each cell; if the first application category is among the preset number of application categories, the first cell is determined to be a target cell suitable for serving the first application category.

The first cell may be any one of the cells.

In implementation, when a cell to be accessed is selected, for a first cell, a first terminal may read application category priority information corresponding to the first cell, and may further determine a preset number of application categories with a highest priority corresponding to the first cell. After determining the preset number of application categories, the first terminal may determine whether the first application category is in the preset number of divided application categories, and if the first application category is in the preset number of application categories, the first terminal may determine the first cell as a target cell suitable for serving the first application category. For the case that the application category priority information is the application category priority list arranged in the order of the service priorities from high to low, when selecting the cell to be accessed, the first terminal may determine whether the first application category is in a first preset number of application categories in the application category priority list, and if so, the first terminal may determine the first cell as a target cell suitable for serving the first application category. When the preset number is 1, the first terminal determines the first cell as the target cell only if the first application type is the highest service priority of the first cell, and when the preset number is M, the first terminal determines the first cell as the target cell as long as the first application type is in the application type priority information corresponding to the first cell.

Optionally, for a case that the base station of the cell further sends a second message to the terminal, correspondingly, the first terminal may receive the second message carrying the application category indication information sent by the base station of the first cell, and correspondingly, the processing procedure in step 205 may be as follows: and if the first application category is not in the application categories with the preset number and is in the application category indication information corresponding to the first cell, determining a target cell suitable for serving the first application category according to the identifiers of other cells corresponding to the first application category in the application category indication information.

In implementation, if the first application category is not in the application category indication information corresponding to the first cell, the first terminal may further determine whether the first application category is in the application category indication information corresponding to the first cell, and if the first application category is in the application category indication information corresponding to the first cell, the first terminal may determine an identifier of another cell corresponding to the first application category in the application category indication information, where the determined identifier of the another cell may be a frequency point number or a frequency band number of the corresponding cell, and further, may re-search the cell according to the identifier of the another cell, and determine a target cell suitable for serving the first application category, where processing after searching the corresponding cell is the same as a processing manner of the first cell, and is not repeated here.

Optionally, for the case that the preset number is less than M, the corresponding processing procedure of step 205 may be as follows: and if the first application category is not in the application category indication information corresponding to the first cell and the first application category is in the application category priority information corresponding to the first cell, determining the first cell as a target cell suitable for serving the first application category, wherein the preset number is smaller than the number of the application categories contained in the application category priority information of the first cell.

In implementation, if the first application category is not in the preset number of application categories and the first application category is not in the application category indication information corresponding to the first cell, the first terminal may further determine whether the first application category is in the application category priority information corresponding to the first cell, and if the first application category is in the application category priority information corresponding to the first cell, the first terminal may determine the first cell as a target cell suitable for serving the first application category. Otherwise, the first terminal may re-search for cells and determine a target cell suitable for the first application category.

In step 206, the first terminal accesses the target cell.

In implementation, after the first terminal determines a target cell to be accessed, the first terminal may initiate random access to the cell to access the target cell.

In addition, in a case that the first terminal accesses the target cell, when the target cell is no longer suitable for serving the application category to which the first terminal currently corresponds, the first terminal may switch the cell in a state of accessing the target cell, that is, the embodiment of the present disclosure further provides a method for switching the cell, and the following details about the processing flow shown in fig. 3 with reference to the embodiment may be as follows:

in step 301, in a state that the first terminal accesses the target cell, if the target cell is not suitable for serving the application category currently corresponding to the first terminal, the base station determines a second cell suitable for serving the application category currently corresponding to the first terminal.

The base station may be the above-mentioned base station, and is a base station corresponding to the target cell.

In implementation, when the application type corresponding to the target cell changes or the application type priority information corresponding to the target cell changes in a state where the first terminal accesses the target cell, the target cell may no longer be suitable for serving the application type currently corresponding to the first terminal. If the target is not suitable for serving the application class to which the first terminal currently corresponds, the base station may determine a second cell suitable for serving the application class to which the first terminal currently corresponds.

Optionally, when receiving a notification signaling sent by the first terminal to indicate that the current corresponding application category is changed, it may be determined that the target cell is already not suitable for serving the current corresponding application category of the first terminal, and accordingly, the processing procedure in step 301 may be as follows: under the state that the first terminal is accessed into the target cell, if a notification signaling which is sent by the first terminal and used for indicating that the current corresponding application category changes is received, determining the second application category as the current corresponding application category of the first terminal; and determining a second cell suitable for serving the application category currently corresponding to the first terminal. Accordingly, the processing procedure of the terminal may be as follows: in the state of accessing the target cell, when the application category corresponding to the target cell is switched from the first application category to the second application category, if the target cell is not suitable for serving the second application category, a notification signaling for indicating that the current corresponding application category is changed is sent to a base station of the target cell.

In implementation, in a state of accessing the target cell, when the application category corresponding to the first terminal is switched from the first application category to the second application category, the first terminal may re-determine whether the target cell is suitable for serving the second application category, where the determination may be performed according to the manner for determining the target cell. If the target cell is not suitable for serving the second application category, the first terminal may send, to the base station of the target cell, a notification signaling for indicating that the application category corresponding to the first terminal changes, where the signaling may be an RRC signaling or an MAC layer signaling, and the notification signaling may also carry an identifier of the second application category.

After receiving the notification signaling sent by the first terminal and used for indicating that the current corresponding application category changes, the base station may determine that the target cell is not suitable for serving the current corresponding application category of the first terminal, and may further determine a cell (may be referred to as a second cell) suitable for serving the current corresponding application category of the first terminal, that is, may determine a second cell suitable for serving the second application category.

Optionally, for a situation that the application category priority information corresponding to the target cell is changed, correspondingly, the processing procedure in step 301 may be as follows: when the application type priority information corresponding to the target cell is changed in a state that the first terminal is accessed into the target cell, if the target cell is not suitable for serving the first application type corresponding to the first terminal, a second cell suitable for serving the application type corresponding to the first terminal at present is determined.

In implementation, the application class priority information of the target cell may be changed in a state where the first terminal accesses the target cell. When the change occurs, the base station may determine whether the target cell is still suitable for serving the first application category corresponding to the first terminal, and may determine a second cell suitable for serving the application category currently corresponding to the first terminal if the target cell is not suitable for serving the first application category corresponding to the first terminal.

Optionally, the process of determining the second cell suitable for serving the application category currently corresponding to the first terminal may be as follows: determining a measurement result reported by a first terminal; and determining the cell which has the cell signal strength meeting the cell switching condition and is suitable for serving the application type currently corresponding to the first terminal in the measurement result as a second cell suitable for serving the application type currently corresponding to the first terminal.

In implementation, in general, the base station may issue measurement configuration information to the first terminal, where the measurement configuration information may be used to instruct the first terminal to measure a cell of a specific frequency point or frequency band, and after the first terminal measures the cell, the first terminal may report a measurement result to the base station.

In a state that the first terminal is accessed to the target cell, if the target cell is not suitable for serving the application category currently corresponding to the first terminal, the base station may obtain a measurement result reported by the first terminal, and further, may determine whether a cell having a cell signal strength that meets a cell switching condition (for example, the cell signal strength is greater than a preset cell switching threshold) and is suitable for serving the application category currently corresponding to the first terminal exists in the measurement result (where the base station may determine whether the first cell is suitable for serving the first application category according to the first terminal), and if the cell exists, may determine the cell as a second cell suitable for serving the application category currently corresponding to the first terminal. In addition, if there are a plurality of cells satisfying the above condition, the base station may determine a cell in which the cell signal strength is the largest as the second cell.

Optionally, for the case of the cell that does not satisfy the above condition in the measurement result, correspondingly, the processing procedure for the base station to determine the second cell may be as shown in fig. 4:

in step 401, if there is no cell whose cell signal strength satisfies the cell handover condition and is suitable for serving the application category currently corresponding to the first terminal in the measurement result, the base station determines a pilot frequency cell suitable for serving the application category currently corresponding to the first terminal.

In implementation, if there is no cell whose cell signal strength satisfies the cell handover condition and is suitable for serving the application category currently corresponding to the first terminal in the measurement result (where the cell may be any cell suitable for serving the application category currently corresponding to the first terminal, or the cell may be any intra-frequency cell suitable for serving the application category currently corresponding to the first terminal), the base station may determine, in each cell (where each cell herein may be each neighboring cell of the target cell), an inter-frequency cell suitable for serving the application category currently corresponding to the first terminal based on application category priority information corresponding to each cell, where a frequency point or a frequency band corresponding to the inter-frequency cell is different from a frequency point or a frequency band currently measured by the first terminal.

In step 402, the base station sends pilot frequency measurement control signaling for instructing measurement of the pilot frequency cell to the first terminal.

In implementation, after determining the inter-frequency cell, the base station may send an inter-frequency measurement control signaling for instructing measurement of the inter-frequency cell to the first terminal. Specifically, after the pilot frequency cell is determined, a pilot frequency measurement control signaling carrying a frequency point or a frequency band corresponding to the pilot frequency cell may be sent to the first terminal.

In step 403, the first terminal receives an inter-frequency measurement control signaling sent by the base station of the target cell and used for instructing measurement on the inter-frequency cell.

In implementation, after the base station sends the inter-frequency measurement control signaling to the first terminal, the first terminal may receive the inter-frequency measurement control signaling sent by the base station and used for instructing measurement on the inter-frequency cell.

In step 404, the first terminal measures the inter-frequency cell and sends the measurement result to the base station of the target cell.

In implementation, after receiving a pilot frequency measurement control signaling carrying a frequency point or a frequency band corresponding to a pilot frequency cell, the first terminal may measure the pilot frequency cell of the frequency point or the frequency band, and at the same time, continue to measure a cell (which may be referred to as a common-frequency cell) of the original frequency point or frequency band. After performing the measurement, the first terminal may send the measurement result to the base station.

In step 405, the base station receives the measurement result sent by the first terminal.

In step 406, the base station determines, according to the measurement result, a second cell whose cell signal strength satisfies the cell handover condition and is suitable for serving the application category currently corresponding to the first terminal.

The measurement result may include a measurement result obtained after the measurement is performed on the inter-frequency cell and the measurement is performed on the intra-frequency cell, and the measurement result may include a measurement result corresponding to the inter-frequency cell and/or a measurement result corresponding to the intra-frequency cell.

In implementation, after receiving the measurement result sent by the first terminal, the base station may determine, based on the measurement result, that the cell signal strength satisfies the cell handover condition and is suitable for serving a second cell of the application category currently corresponding to the first terminal.

In step 302, the first terminal is handed over to the second cell.

In implementation, after the base station determines the second cell, the first terminal may be handed over to the second cell.

In addition, the above process is directed to the case: and when the target cell is not suitable for serving the application category currently corresponding to the first terminal, switching the cell under the state of being connected with the target cell. Optionally, when the target cell is not suitable for serving the application category currently corresponding to the first terminal, the first terminal may release the current connection, and accordingly, a processing procedure of the first terminal may be as follows: in the state of accessing the target cell, if the target cell is not suitable for serving the second application type, releasing the current connection, and re-determining the second cell suitable for serving the current corresponding application type; and accessing the second cell.

In an implementation, in a state that the first terminal accesses the target cell, when the application category priority information corresponding to the target cell is changed, the first terminal may determine, based on the changed application category priority information, whether the target cell is suitable for serving the application category (i.e., the first application category) currently corresponding to the first terminal, and if the target cell is not suitable for serving the first application category, the first terminal may release the current connection, re-determine a second cell suitable for serving the first application category, and further may access the second cell, where the first terminal may determine the second cell according to the method for determining the first cell. That is, in the state of accessing the target cell, when the application category priority information of the target cell is changed, if the target cell is not suitable for serving the second application category, the current connection is released, and the second cell suitable for serving the current corresponding application category is determined again; and accessing the second cell.

When the application category currently corresponding to the first terminal is switched from the first application category to the second application category, it may also be determined whether the target cell is suitable for serving the application category currently corresponding to the first terminal (i.e., the second application category), and if the target cell is not suitable for serving the second application category, the first terminal may release the current connection, re-determine the second cell suitable for serving the second application category, and further may access the second cell, where the first terminal may determine the second cell according to the method for determining the first cell. That is, in the state of accessing the target cell, when the application category currently corresponding to the first terminal is switched from the first application category to the second application category, if the target cell is not suitable for serving the second application category, the current connection is released, and the second cell suitable for serving the currently corresponding application category is re-determined; and accessing the second cell.
