Technical Field

The present application relates to the field of computer technologies, and in particular, to a cell switching method and apparatus, a storage medium, and an electronic device.

Background

With the continuous development of the fifth generation mobile communication technology (5G), the 5G network performs early network deployment in a non-independent networking mode, and a user using a 5G terminal supporting the non-independent networking mode to perform communication can obtain a faster and more efficient communication transmission experience.

In the related art, a non-independent Networking (NSA) mode is adopted, and a scheme of dual connectivity mode (EUTRAN + new radio-dual connectivity, EN-DC) is generally adopted in a networking process to perform cell network deployment. For example, a core idea of a dual connectivity mode scheme is to use a 4G Cell (also called Long Term Evolution (LTE)) as a Master Cell Group (MCG) and a 5G Cell as a Secondary Cell Group (SCG) to deploy a network scenario in which 4G +5G coexist.

Since the non-independent networking mode relies on the core network corresponding to the LTE cell to establish the 5G network connection, in an actual application process, the terminal performs cell switching based on the signal quality of the current network-residing cell and the neighboring cell and the cell switching criteria (such as cell reselection and redirection criteria) in the related technology.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.

In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it is noted that, unless explicitly stated or limited otherwise, "including" and "having" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the related art, since the non-independent networking mode relies on the core network corresponding to the LTE cell to establish the 5G network connection, in an actual application process, the terminal performs cell switching based on the signal quality of the current camped cell and the adjacent cell and the cell switching criteria (such as cell reselection and redirection criteria) in the related art.

When the terminal is in the dual-connection mode, the dual-connection network corresponding to the dual-connection mode is as follows: a first network: 4G network, second network: for example, in a 5G network (at this time, the terminal may provide a 5G network service to the outside), the signal quality of the neighboring cell meets the cell switching criterion, and when the neighboring cell only supports the first network (e.g., a 4G network), the terminal is switched from the current network-residing cell to the neighboring cell, and the terminal falls back from the 5G network to the 4G network, on one hand, the network residence time of the terminal in the 5G network is reduced, which causes instability of the terminal network; on the other hand, the service rate of the terminal is reduced because the service capability of higher rate compared with the 4G network cannot be provided.

The present application will be described in detail with reference to specific examples.

Fig. 1 is a schematic diagram of a communication system architecture provided in the present application.

Referring to fig. 1, the communication system includes a user terminal 100, an LTE base station 110, an NR base station 120, and a core network 130. The LTE base station 110 may provide 4G network wireless access for one or more user terminals 100 within a coverage area, enabling the user terminals to communicate with each other; NR base station 120 may provide 5G network radio access for one or more user terminals 100 within a coverage area to enable the user terminals to communicate with each other. In the 5G dependent networking system, the LTE base station 110 and the NR base station 120 share the core network 130, and data, signaling, and the like are transmitted with one of the LTE base station 110 and the NR base station 120 as a primary station and the other as a secondary station.

The user terminal 100 includes, but is not limited to, a Mobile Station (MS), a mobile terminal device (mobile terminal), a mobile phone (mobile phone), a handset (handset), a portable device (portable device), and the like, and the terminal device may communicate with one or more core networks via a Radio Access Network (RAN), for example, the terminal device may be a mobile phone (or referred to as a "cellular" phone), a computer with a wireless communication function, and the terminal device may also be a portable, pocket, hand-held, computer-embedded, or vehicle-mounted mobile device or device.

A base station, i.e. a public mobile communication base station, is an interface device for a mobile device to access the internet, and is a form of a radio station, which is a radio transceiver station for information transmission with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. The base station can also be called a base station system and consists of a plurality of independent base station devices, and a complete base station device also comprises a power supply, a storage battery, an air conditioner, security monitoring and other matched devices. The LTE Base station 110 mainly includes three parts, namely, a BBU (Building Base band Unit), an RRU (Radio Remote Unit), and a Radio frequency antenna, where the BBU is mainly responsible for signal modulation, the RRU is mainly responsible for Radio frequency processing, and the antenna is mainly responsible for conversion between cable uplink guided waves and spatial waves in the air. Compared with the LTE base station, the NR base station 120 combines an RRU and a radio frequency Antenna before the LTE base station into an AAU (Active Antenna Unit), and connects the AAU with a BBU through an optical fiber. According to the station type size and power of the base station, the base station can be divided into a macro base station (macro site), a micro base station (micro site), a pico base station (PicoSite) and a femto base station (FemtoSite): the single carrier transmitting power of the macro base station is more than 10W, and the coverage radius is more than 200 meters; the single carrier transmitting power of the micro base station is 500mW to 10W, and the coverage radius is 50 meters to 200 meters; the single carrier transmitting power of the pico-base station is between 100mW and 500mW, and the coverage radius is between 20 meters and 50 meters; the single carrier transmission power of the femto base station is less than 100mW, and the coverage radius is between 10 meters and 20 meters.

The core network 130 is the most core part of the communication network, and is an information processing center, and generally, one core network can process data of thousands or tens of thousands of base stations, and is mainly responsible for processing and routing of data. The core network 130 can provide user connection, user management, and service bearer functions, and can serve as a bearer network to provide an interface to an external network; the establishment of user connection includes functions such as MM (mobility management), CM (call management), switching/routing, and recording notification (connection relation to peripheral equipment of the intelligent network is completed by combining with the intelligent network service); the user management comprises user description, description of Quality of Service (Qos) of a user, user communication record (Accounting), VHE (Virtual Home Environment) provided by a session with an intelligent network platform, and security (corresponding security measures provided by an authentication center); service bearers include PSTN (Public Switched Telephone Network), external circuit data networks and packet data networks, Internet (Internet) and Intranets (Intranets), and SMS (Short Message Service) to the outside, among others.

In the following method embodiments, for convenience of description, only the main execution body of each step is described as a terminal.

In one embodiment, as shown in fig. 2, a cell handover method is proposed, which may be implemented in dependence on a computer program, operable on a cell handover device based on the von neumann architecture. The computer program may be integrated into the application or may run as a separate tool-like application.

Specifically, the cell switching method includes:

step S101: and determining a target cell to be switched when the mobile terminal is in the dual-connection mode.

For convenience of understanding, some contents (such as the dual connection mode) related to the embodiment of the present invention are described below:

in the initial stage of the 5G (5th-Generation, fifth Generation) mobile communication technology going from theory to practice, each large operator usually adopts an EN-DC (EUTRAN + New Radio-dual connectivity, 4G +5G dual connectivity) scheme, that is, a non-independent Networking (NSA) mode for networking, in consideration of cost and later-stage technology iteration. The core idea of the scheme is to adopt a 4G Cell as an MCG (Master Cell Group), a 5G (5th Generation Mobile Networks, 5G) Cell as an SCG (Secondary Cell Group), and deploy a 4G +5G coexisting network scene. It can be understood that the dual connectivity network corresponding to the dual connectivity mode may be a 4G network and a 5G network, and further, when the electronic device supports the dual connectivity mode, that is, supports EN-DC dual connectivity, the terminal may be in a network scenario where 4G +5G coexist, that is, in the dual connectivity mode.

In a network scene with coexisting 4G +5G, the terminal can execute a main control flow on the 4G cell and speed up through the 5G auxiliary cell group so as to achieve the characteristics of high speed, low time delay and the like of 5G.

In specific implementation, if the terminal needs to acquire a service from the 5G network in the current network-residing cell supporting the EN-DC, and if the speed needs to be increased or a large amount of data needs to be transmitted, a 5G network (which may also be understood as allocating a 5G site) may be configured for the terminal through an RRC (Radio Resource Control) reconfiguration message of the 4G network under the dual-connection mode architecture, so that the terminal may perform speed increase or data transmission through the 5G network, so as to achieve characteristics of 5G, such as high speed, low delay, and the like.

The target cell to be switched is mostly determined in a 4G neighboring cell of the current network-camped cell, where the 4G neighboring cell refers to a 4G cell adjacent to the current 4G serving cell in cellular communication, and is a target cell that can be selected by the terminal when switching the current serving cell. The EN-DC mode refers to a dual-connection mode in which a 4G radio access network and a 5G NR access network simultaneously establish network connection, that is, an EN-DC (option 3) architecture in a new wireless dual-connection architecture of 4G LTE and 5G NR for non-independent networking: in the non-independent networking mode, the UE establishes connection with a 4G core network, simultaneously uses radio resources of at least two different base stations (the 4G base station is a main station and the 5G base station is a slave station), carries data shunting to the at least two different base stations on a PDCP layer, and the PDCP layer on the main station is responsible for PDU numbering, data shunting and aggregation between the main station and the slave station and the like.

As can be seen, compared with a single Long Term Evolution (LTE) cell supporting only a 4G network, the Long Term Evolution (LTE) cell under the dual connectivity mode architecture may further be used to control the configuration of the 5G cell. The 4G cell under the dual connectivity mode architecture already has some characteristics (such as high speed and low delay) of the 5G cell, and can simultaneously support the 4G network service and the 5G network service, that is, the terminal is in the dual connectivity mode.

In practical applications, the terminal mobility management may involve a mobile management procedure such as cell reselection, cell selection, cell handover, cell registration, measurement report, and the like due to a change in an environment in which the terminal is located, and the target cell may be understood as a serving cell to be handed over, which is determined by the terminal based on the corresponding terminal mobility management, such as a reselected cell whose signal quality is determined based on the cell reselection procedure and is better than a currently camped cell, such as a cell which is determined based on the cell selection procedure and is better than the currently camped cell, and the like due to a change in an environment in which the terminal is located.

The cell refers to a network cell that can currently provide service data transmission service for a terminal, and it can be understood that a current network-residing cell is also referred to as an area where the terminal can currently obtain network service (e.g., LTE network service), and is a cell divided from a whole communication service area (e.g., LTE communication service area), a base station for communication is provided in the cell, and is responsible for establishing wireless connection with a terminal in the cell, and a terminal supporting a communication system (e.g., LTE communication system) corresponding to the communication service can communicate in any cell in the communication service area, for example, the service cell or a target cell to be switched can carry service data downloaded by a network.

In an actual application environment, when the overall coverage of a cell is better, a terminal may be simultaneously covered by multiple cells (e.g., 2 to 3 cells) in a moving or stationary process, where each cell may be a cell in a same system (also referred to as a same system) as a cell where the terminal currently resides in a network, or a cell in a different system (also referred to as a different system) as a serving cell of the terminal currently resides in the network.

In a specific implementation scenario, the terminal may be a device providing a network download service to a user, and in order to provide a high-speed low-latency network download service for the user, the terminal is in a dual-connection mode, and the terminal may execute a main control process on a current network-camped cell (an LTE cell supporting endec), and perform network speed-up based on a 5G auxiliary cell group configured by the current network-camped cell (the LTE cell supporting endec), so as to achieve characteristics of 5G, such as high speed low latency. However, during the terminal moving process, the cell signal quality of the current network-camped cell of the terminal may fluctuate or change, or even trigger the terminal mobility management, such as based on the cell selection procedure, the cell handover procedure, and the cell reselection procedure in the related art, and based on the terminal mobility management, the terminal may determine a target cell to be handed over. Usually, the signal quality of the target cell is higher than that of the currently camped cell within a certain time, and in some cases, in view of providing high-speed and low-delay service for the user, in some cases, if the terminal can continue to camp in the dual connectivity mode subsequently, the user on the terminal can be provided with high-speed data service based on the 5G network. However, if the target cell to be switched cannot support the endec (dual connectivity mode), then when the user needs the terminal to provide high-rate data service, the 5G secondary cell group cannot be configured to perform network speed-up in an actual network environment.

In order to explain the cell handover technology related to the embodiment of the present application, the following is specifically explained by cell reselection in terminal mobility management, and specifically as follows:

LTE cell reselection (cell reselection) can be understood as a process in which a terminal selects a best cell to provide a service signal by monitoring signal qualities of neighboring cells and a currently camped cell in an idle mode. When the signal quality and the signal level of the neighboring cell satisfy the S criterion in the related art and satisfy a certain reselection decision criterion, the neighboring cell may generally be used as a target cell to be switched, which is determined by the terminal. In the reselection process of the LTE cell, after the UE (terminal) successfully resides in the current network-residing cell, the measurement of the cell is continuously carried out. The RRC layer calculates Srxlev (S criterion) according to the RSRP measuring result, compares the Srxlev with Sintrasearch (same frequency measurement starting threshold) and Snonitrasearch (different frequency/different system measurement starting threshold) to determine whether to start the adjacent region measurement, and when measuring,

1. when the priority indicated by the system message sent by the network side (communication network) is higher than the serving cell, the UE (terminal) always performs measurement on the high-priority cells;

2. for cells with same frequency/priority, if the current network-residing cell is less than or equal to Sintrasearch (same frequency measurement starting threshold), the UE (terminal) executes cell measurement, and the cell measurement is lower than the non-measurement;

3. when the system message indicates that the priority is lower than that of the current network-residing cell, if the S value of the current network-residing cell is less than or equal to Snonintrasearch (pilot frequency/pilot system measurement starting threshold), executing cell measurement, and if the S value is greater than the S value, not measuring;

4. and if the Snonintrasearch parameter is not broadcasted in the system message, the UE starts the inter-frequency cell measurement. Wherein: the S value is Srxlev (S criteria) in the cell selection,

further, based on the cell measurement result, in the process of determining the target cell to be switched, if a plurality of adjacent cells on the highest priority meet the conditions, the optimal cell on the frequency with the highest priority is selected as the target cell. And for the frequency points with the same priority (or the same frequency), determining the target cell to be switched by adopting the R criterion of reselecting the cells with the same frequency.

For cells with same frequency or different frequencies but with the same priority, the UE (terminal) adopts the R criterion to reselect and sort the cells. The R criterion is that the target cell continuously exceeds Rs (serving cell) during Treselection time (treselections of same and different frequencies may be different), and then the UE determines the target cell to be handed over.

It should be noted that, in the embodiment of the present application, after the terminal determines the target cell to be handed over, by executing the cell handover method of the embodiment of the present application, the terminal does not immediately handover to the target cell, but further refers to a network type supported by the target cell, and performs a secondary decision on the target cell, thereby determining whether to handover the target cell.

Step S102: and if the target cell supports the double-connection network, switching from the current network-residing cell to the target cell, wherein the double-connection network is a network corresponding to the double-connection mode.

The current network-residing cell is a network-residing cell which provides service data transmission service for a terminal at present, and the current network-residing cell is also called an area where the terminal can obtain network service (such as LTE network service and 5G network service) at present, and is a cell divided from the whole communication service area (such as a dual-connection communication service area), wherein a base station for communication is arranged in the cell, and is responsible for establishing wireless connection with the terminal in the cell, and the terminal supporting the communication system (such as LTE and 5G communication system) corresponding to the communication service can communicate in any cell in the communication service area, for example, the service cell is used for bearing service data of high-definition video call.

The Base Station provides Network service for a communication System (communication System) corresponding to a serving cell, and the Base Station includes, but is not limited to, a Base Transceiver Station (BTS) in a Global System for Mobile communication (GSM) System or a Code Division Multiple Access (CDMA) System, a Base Station (NodeB ) in a Wideband Code Division Multiple Access (WCDMA) System, an evolved Node B (eNB, eNodeB) in a Long Term Evolution (Long Term Evolution, LTE) System, or a wireless controller in a Cloud Radio Access Network (CRAN). And so on.

Specifically, in the process of terminal movement, the cell signal quality of the current network-residing cell of the terminal may fluctuate or change, or even trigger terminal mobility management, such as cell selection flow, cell handover flow, and cell reselection flow in the related art, and based on the terminal mobility management, the terminal may determine a target cell to be handed over. Usually, the signal quality of the target cell is higher than that of the current network-camped cell within a certain time, and in some cases, in view of providing high-speed and low-delay service for the user, in general, if the terminal can continue to be in the dual-connection mode subsequently, the user on the terminal can be provided with high-speed data service based on the 5G network, in the case that the transmission quality of some service data is high. However, if the target cell to be switched cannot support the endec (dual connectivity mode), then when the user needs the terminal to provide high-rate data service, the 5G secondary cell group cannot be configured to perform network speed-up in an actual network environment.

Further, after determining a target cell to be switched, the terminal may acquire a network type supported by the target cell, for example, the target cell only supports a first network (e.g., an LTE network) in a dual connectivity network, for example, the target cell supports the dual connectivity network, and so on. And judging whether to switch to the target cell or not based on the network type by acquiring the network type of the target cell.

Specifically, the terminal may obtain cell information (such as a cell name, a cell frequency band, a cell frequency, and other information) corresponding to the target cell, and determine a network supported by the target cell based on the cell information, which is specifically as follows:

in a possible implementation manner, the terminal may be provided with a cell set, where the cell set includes a plurality of network cells and networks supported by the network cells, and the terminal may obtain cell information of a target cell, such as a cell identifier (e.g., a cell name), then search network information corresponding to the target cell in the cell set according to the cell information, and obtain a network supported by the target cell based on the network information, such as a network in which the cell supports only LTE, such as a network in which the target cell supports NR, such as a network in which the target cell supports dual connectivity, and so on.

In a possible implementation manner, a terminal may obtain a system message (also referred to as a system message block) sent or broadcast by a communication network corresponding to a target cell, and in practical applications, a generally determined target cell is mostly a cell supporting a first network, such as an LTE cell supporting an LTE network, and the terminal may obtain whether a network field exists in the system message block, where the network field may be one of cell information immediately and may be used to characterize a network type of the target cell, and a specific network field is used to characterize whether the target cell supports a dual connectivity mode, and in some embodiments, may also be understood as whether a 5G network corresponding to the dual connectivity mode may be supported, and after obtaining the network field, it is detected whether the network field is a specified value, it may be understood that when the network field is a specified value (such as true), and characterizing the target cell to support the 5G network.

Further, in practical application, a system message sent by a network side (i.e., a communication network system) may include many fields, and when the system message includes a specific network field and the value of the network field is a specified value for different network systems, it is determined that the target cell supports a dual connectivity mode, that is, the target cell may provide a network service corresponding to a dual connectivity network for an electronic device residing on the cell; for example, when an upperLayerIndication-r15 field exists in a system message (SIB2 message block) on the network side, and the value of the field is true, it indicates that the target cell supports the dual connectivity mode, that is, the target cell supports the cell of the ENDC network; when the upperLayerIndication-r15 field exists in the system message of the LTE network, but the value of the field is not true and is false, which indicates that the target cell does not support the dual-connectivity network in the ENDC mode, and usually only supports the LTE network.

Specifically, after determining the network supported by the target cell in the above manner, it can be understood that, if the target cell supports the dual connectivity mode, under the condition that some service data transmission quality requirements are high, in view of providing a high-speed low-delay service for a user, after the terminal is switched from the current network-residing cell to the target cell, the terminal may continue to reside in the dual connectivity mode according to a service transmission requirement, for example, when the user needs the terminal to provide a high-speed data service, in an actual network environment, the target cell may configure a 5G auxiliary cell group to perform network speed increase. And providing high-speed low-delay data service for the user on the terminal based on the dual-connection mode.

In some implementation scenarios, after the terminal determines the target cell to be handed over, if the target cell is a cell that only supports a second network in a dual connectivity network, where in some embodiments, only the cell that supports the second network may be understood as an NR cell that supports a 5G network in an independent networking (SA) manner, at this time, the target cell supports a 5G network service, and subsequently, when the user needs to provide a high-rate data service, the terminal may directly provide the high-rate low-latency data service for the user on the terminal through the NR cell that supports the 5G network, that is, the terminal may be handed over from a current network-camped cell to the target cell.

The determination process of determining that the target cell is the cell supporting only the second network in the dual connectivity network by the terminal is similar to the above explanation, and one way may be to obtain cell information of the target cell, such as a cell identifier (e.g., a cell name), then search network information corresponding to the target cell in the cell set according to the cell information, and obtain a network supported by the target cell, such as the second network in the dual connectivity network, such as the NR network supported by the target cell, based on the network information. One way may be: the terminal may obtain a system message (also referred to as a system message block) sent by or broadcasted by a communication network corresponding to the target cell, in the system message, in an actual application, the system message sent by a network side (that is, the communication network system) may include many fields, and when the system message includes a specific network field and a value of the network field is a specified value corresponding to the second network (for example, a network field that only supports an NR network) for different network systems, the target cell is determined to be a cell that only supports the second network in the dual connectivity network.

Step S103: and if the target cell only supports the first network in the dual-connection network, continuing to reside in the current network-residing cell.

The first network has a lower network priority than the second network, and in practical applications, network characteristics such as uplink and downlink speeds, network delays, and transmission capacities of the second network are higher than those of the first network. In some embodiments, the first network may be an LTE network and the second network may be an NR network.

For convenience of explanation, the first network is often explained as an LTE network, and the second network is often explained as an NR network, and it should be noted that the following explanation does not limit specific network types of the first network and the second network.

Specifically, after determining the network supported by the target cell in the above manner, it can be understood that, if the target cell only supports the first network (e.g. an LTE network), under the condition that some service data transmission quality requirements are high, generally, after the terminal is switched from the current network-camped cell to the target cell only supporting the first network, if the user subsequently needs to provide a high-rate data service by the terminal, the terminal can only provide a network service to the user through the first network, and generally, based on the network service of the first network, the rate is low and the delay is high. Therefore, in this embodiment of the present application, when the target cell only supports the first network, in order to provide a high-rate low-latency data service for a user on the terminal at a later stage, the terminal may not switch from the current network-camped cell to the target cell, and may select to continue camping on the current network-camped cell.

In the embodiment of the application, a terminal determines a target cell to be switched when the terminal is in a dual connectivity mode, and if the target cell supports the dual connectivity network, the terminal switches from a current network-residing cell to the target cell, and if the target cell only supports a first network in the dual connectivity network, the terminal continues to reside in the current network-residing cell. By combining the network types supported by the target cell and bringing the network types into the cell switching process for reference, the residence time of the terminal in the dual-connection network corresponding to the dual-connection mode can be greatly prolonged, the network quality is improved, frequent switching of the cell network can be avoided, a high-rate service can be continuously provided for a user on the terminal based on the dual-connection mode, and the service capability of the terminal is improved.

Referring to fig. 3, fig. 3 is a flowchart illustrating a cell handover method according to another embodiment of the present application. Specifically, the method comprises the following steps:

step S201: determining a target cell to be switched when the target cell is in a dual-connection mode;

specifically, refer to step S101, which is not described herein again.

Step S202: acquiring cell information corresponding to the target cell;

the Cell information is used for uniquely representing the information of the Cell identity, wherein the Cell information includes but is not limited to one or more of the combination of Physical Cell type, geographical latitude where the Cell is located, Cell direction angle, Cell identity (PCI), Cell carrier frequency (carrier freq), target transmission power corresponding to the Cell, UE (terminal) context information, SAE bearer ID, SAE bearer QOS parameter, RRC context information, and the like.

In practical application, in the process of moving the terminal, the cell signal quality of the current network-resident cell of the terminal fluctuates or changes, and even triggers terminal mobility management, so that in the process of determining the target cell to be switched, the terminal can request cell information from the target cell, and the terminal can also acquire the cell information of the target cell in a cell measurement mode.

Step S203: and determining the network supported by the target cell based on a pre-stored dual-connection cell list and the cell information.

The dual connectivity cell list includes information of a plurality of cells, such as cell information corresponding to each cell and a dual connectivity flag corresponding to the cell; wherein the dual connectivity flag (EndcFlag) is used for characterizing networks supported by the corresponding cell, such as dual connectivity mode, LTE-only network support, and the like. It can be understood that, in the dual connectivity list pre-stored in the terminal, the cell information and the dual connectivity flag corresponding to each cell and the device have a unique mapping relationship, so that when the terminal determines a network supported by a target cell, the terminal can directly obtain the dual connectivity flag corresponding to the cell information in the dual connectivity list based on the cell information of the target cell, and further determine the network supported by the target cell.

Specifically, the terminal may collect (e.g., collect a period of time) the detected cells, the cell information corresponding to each cell and the supported network in advance in an actual network environment, and then generate a dual connectivity cell list based on the cell information corresponding to each of the plurality of cells and the supported network, and store the dual connectivity cell list locally. The dual connectivity flag (EndcFlag) is determined based on a network supported by the cell, and if the cell supports the dual connectivity mode, the dual connectivity flag (EndcFlag) may be set as a first flag (e.g., true), and if the cell only supports the LTE network, the dual connectivity flag (EndcFlag) may be set as a second flag (e.g., false), and so on. Further, in some embodiments, if a certain cell supports a second network in the dual connectivity network, an EndcFlag (EndcFlag) may be set as the third flag, for example, taking the second network as an NR network as an example, when a certain cell is deployed in a network, the certain cell may be understood as supporting only the NR network in the dual connectivity network by adopting an independent networking manner.

Specifically, the terminal may determine a dual connectivity flag corresponding to the cell information in a pre-stored dual connectivity cell list, for example, as shown in fig. 4, fig. 4 is a schematic diagram of a dual connectivity cell list, and fig. 3 includes a plurality of cells (e.g., cell 001 and cell 002.), and cell parameters (e.g., BAND frequency BAND, FREQ frequency, PCI cell identifier) corresponding to each cell and an EndcFlag dual connectivity flag of the cell.

When the dual connectivity flag is the first flag, it is determined that the target cell supports the dual connectivity network in the dual connectivity mode (i.e., simultaneously supports the first network and the second network), and if the terminal determines a target cell, the cell information of the target cell is: in frequency band 1, frequency 1, and PCI-1, the terminal may determine, based on the cell information, an EndcFlag dual connectivity flag- "true" uniquely corresponding to the cell information in a pre-stored dual connectivity cell list shown in fig. 3, and further, after determining that the dual connectivity flag- "true" is a first flag, the terminal may determine that the target cell supports the dual connectivity network corresponding to the dual connectivity mode.

When the dual connectivity flag is the second flag, determining that the target cell only supports the first network in the dual connectivity network, if the terminal determines a target cell, the cell information of the target cell is respectively: in frequency band 2, frequency 2, and PCI-2, the terminal may determine, based on the cell information, an EndcFlag dual-connectivity flag- "false" uniquely corresponding to the cell information in a pre-stored dual-connectivity cell list shown in fig. 3, and further, after determining that the dual-connectivity flag- "false" is a second flag, the terminal may determine that the target cell only supports a first network in a dual-connectivity network, such as an LTE network.

Step S204: and if the target cell supports the double-connection network, switching from the current network-residing cell to the target cell.

Specifically, refer to step S102, which is not described herein again.

Step S205: if the target cell only supports the first network in the dual-connection network, when the current network-residing cell meets the cell residing condition, continuing to reside in the current network-residing cell.

The cell residence condition generally requires that a current network residence cell meets a cell selection S criterion, that is, Srxlev >0, in practical application, if a terminal is in a situation where cell coverage is better, a generally determined target cell is a cell with higher signal quality than the current network residence cell, and at this time, there may be a situation where service quality of the current network residence cell meets the cell residence condition, and at this time, it may be considered that, when the target cell is a cell supporting only a first network (such as an LTE network) in a dual connectivity network, handover from the current network residence cell is not needed. Therefore, the situation that the target cell to be switched can not support ENDC (dual connectivity mode) is avoided, and when a user needs a terminal to provide high-speed data service, a 5G auxiliary cell group can not be configured to carry out network speed increase in an actual network environment.

Wherein, the S criterion is an S value corresponding to the cell residence condition, that is, Srxlev (S criterion) in the cell selection, and the formula:

Srxlev＝Qrxlevmeas–qRxLevMin-qRxLevMinOffset)–pCompensation；

wherein, Qrxlevmeas is the measured receiving power of the current network-residing cell, and refers to the RSCP receiving power value of the communication channel (such as P-CCPCH channel);

qRxLevMin is the minimum received power of the current network-residing cell, and the parameter is obtained from the system broadcast message of the network side;

pCompensation is a power compensation value and can be calculated by the company as follows

pCompensation＝max(UE_TXP_WR_MAX_RACH-P_MAX，0)

Wherein, UE _ TXP _ WR _ MAX _ RACH (the maximum transmission power of the terminal on the RACH during the random access) is sent by a system broadcast message and can be generally set to 0, and P _ MAX is the maximum nominal transmission power of the terminal and is related to a reselection trigger condition corresponding to the terminal reselecting the cell.

Further, when the Srxlev value of the current network-residing cell is calculated to be larger than 0, the current network-residing cell is determined to meet the cell residing condition. And then the terminal can simultaneously reduce the switching priority corresponding to the target cell so as to avoid the subsequent generation of the 'ping-pong effect', or repeat the measurement or switching determination process of the target cell. And continuing to camp on the current network-camping cell in the embodiment of the present application, through multiple decisions, when cell handover is involved, the current network-camping cell is handed over or camped on a network cell that can provide a higher network priority than the first network, such as a cell providing 5G network service.

In the embodiment of the application, a terminal determines a target cell to be switched when the terminal is in a dual connectivity mode, and if the target cell supports the dual connectivity network, the terminal switches from a current network-residing cell to the target cell, and if the target cell only supports a first network in the dual connectivity network, the terminal continues to reside in the current network-residing cell. By combining the network types supported by the target cell and bringing the network types into the cell switching process for reference, the network residence time of the terminal in the dual-connection network can be greatly prolonged, the network quality is improved, the frequent switching of the cell network can be avoided, high-rate services can be continuously provided for users on the terminal based on the dual-connection mode, and the service capability of the terminal is improved; the terminal can quickly determine the network type supported by the target cell through the pre-stored dual-connection cell list, so that cell switching can be quickly carried out based on the network type, the judgment time in the cell switching process is shortened, and the cell switching efficiency is improved; and in the process of switching the terminal cell, if the current network-residing cell can normally provide service to the outside (namely, the cell network-residing condition is met), the current network-residing cell can reside on the cell supporting the dual-connection mode as much as possible instead of being switched to the target cell only supporting the first network (such as an LTE network), so that the service rate of the terminal can be effectively improved, the times of cell switching (such as cell reselection) are reduced, and the power consumption of the terminal in the process of cell switching is reduced.

Referring to fig. 5, fig. 5 is a flowchart illustrating a cell handover method according to another embodiment of the present disclosure. Specifically, the method comprises the following steps:

step S301: determining a target cell to be switched when the target cell is in a dual-connection mode;

specifically, refer to step S101, which is not described herein again.

Step S302: and acquiring cell information corresponding to the target cell, and judging whether the pre-stored dual-connection cell list has the cell information.

According to some embodiments, the information of multiple cells is included, such as cell information corresponding to each cell and a dual connectivity flag corresponding to the cell; the dual connectivity flag (EndcFlag) is used to characterize the networks supported by the corresponding cell, such as the dual connectivity network corresponding to the dual connectivity mode, the first network only, and so on. It can be understood that, in a dual connectivity list pre-stored by a terminal, cell information and a dual connectivity flag corresponding to each cell and its device have a unique mapping relationship, so as to facilitate the terminal to determine a network supported by a target cell.

For the step of obtaining the cell information corresponding to the target cell, refer to step S202 specifically, and are not described herein again.

Step S303: if the cell information does not exist in the dual-connection cell list, a system message block corresponding to the target cell is obtained, a dual-connection mark corresponding to the target cell is determined based on the system message block, and the cell information and the dual-connection mark are added to the dual-connection cell list.

In practical applications, a generally determined target cell is mostly an LTE cell, and the terminal may obtain whether a dual connectivity flag (i.e., a specific network field in the message block) exists in the system message block, where the dual connectivity flag is used to characterize whether the target cell supports a dual connectivity network, in some embodiments, it may be determined whether the target cell can support a corresponding 5G network in a dual connectivity mode based on the dual connectivity flag, and after obtaining the dual connectivity flag, it is detected whether the dual connectivity flag is a specified value (e.g., a first flag), and it may be understood that when the network field is the first flag (e.g., true), the target cell is characterized to support the dual connectivity network.

Further, in practical application, a system message sent by a network side (i.e., a communication network system) may include many fields, and different fields may correspond to different network systems, and if the field includes a specific dual connectivity flag and the value of the dual connectivity flag is a specified value (e.g., a first flag), it is determined that the target cell supports a dual connectivity network; for example, when an upperlayer indication-r15 field exists in a system message (SIB2 message block) on the network side and the value of the field is true (which can be understood as a first flag), it indicates that the target cell supports the dual connectivity mode, that is, the target cell supports a cell of the endec network; when the superLayerIndication-r 15 field exists in the system message of the LTE network, but the value of the field is not true and is false (which can be understood as a second flag), it indicates that the target cell does not support the ENDC network, and only supports the LTE network.

Then, the terminal establishes a mapping relation between cell information corresponding to the target cell and the dual connectivity indicator, and adds the cell information and the dual connectivity indicator to the dual connectivity cell list. Thereby completing the updating and maintaining process of the dual-connection cell list.

Step S304: and if the dual-connection cell list has the cell information, determining a network supported by the target cell based on a pre-stored dual-connection cell list and the cell information.

Specifically, refer to step S203, which is not described herein again.

Step S305: and if the target cell supports the double-connection network, switching from the current network-residing cell to the target cell.

Specifically, refer to step S103, which is not described herein again.

Step S306: if the target cell only supports the first network, when the current network-residing cell does not meet the cell-residing condition, acquiring a neighbor cell list of the current network-residing cell, wherein the neighbor cell list comprises at least one neighbor cell.

Steps S201 to S205 may be referred to for determining that the target cell only supports the first network and determining that the current camping cell does not satisfy the relevant definitions of the cell camping condition, and details are not repeated here.

Specifically, if the target cell only supports a first network, such as an LTE network, when the current camped cell does not satisfy the cell camping condition, the current camped cell is difficult to provide a corresponding communication service for the user, and it can be understood that when the cell camping condition is not satisfied, a neighbor cell measurement event is inevitably triggered, and the terminal measures a neighbor cell near the current camped cell, thereby generating a neighbor cell list including at least one neighbor cell. Optionally, when determining the target cell to be switched, the terminal may also measure the neighboring cell of the current network-camped cell, and at this time, the terminal may obtain a neighboring cell list including at least one neighboring cell obtained by measurement when determining the target cell before.

The process of measuring the neighboring cell may refer to the definitions of neighboring cell measurement in the related art, and is not described herein again.

Step S307: and acquiring a target double-connection mark corresponding to each adjacent cell in the double-connection cell list.

The target dual connectivity flag may be understood as a dual connectivity flag of an adjacent cell in the dual connectivity cell list, and further, when there is no adjacent cell in the dual connectivity cell list, the target dual connectivity flag of "a certain adjacent cell" may not be obtained. In the embodiment of the present application, a target cell supporting a dual connectivity mode is obtained from each neighboring cell by referring to a dual connectivity list, and in a specific implementation, a target connectivity flag corresponding to neighboring cell information is searched in the dual connectivity list through neighboring cell information of the neighboring cell, for example, a unique target dual connectivity flag is searched according to a frequency band, a frequency, and a PCI of the neighboring cell.

Step S308: and if at least one target double-connection mark exists in each target double-connection mark and is a first mark, determining that a reference cell supporting the double-connection network exists in the neighbor cell list, and switching the current resident network cell to the reference cell.

Specifically, in each target dual connectivity flag, if there is one target dual connectivity flag as the first flag, the terminal may use an adjacent cell corresponding to the first flag as a reference cell supporting the dual connectivity mode, and then may improve the handover priority of the reference cell, so as to preferentially refer to the reference cell based on a normal cell handover procedure, so that the terminal is switched from the current network-camped cell to the reference cell, it can be understood that the reference cell supports the dual connectivity mode, and under the condition that the requirement on the quality of service data transmission is high, in view of providing a high-speed low-delay service for the user, after the terminal is switched from the current network-camped cell to the reference cell, the terminal may continue to camp in the dual connectivity mode subsequently according to the service transmission requirement, for example, when the user needs the terminal to provide a high-speed data service, in an actual network environment, the target cell can configure a 5G auxiliary cell group on the basis of the reference cell for network speed increasing. And providing high-speed low-delay data service for the user on the terminal based on the dual-connection mode.

Further, when the number of the reference cells is multiple, that is, there are multiple target dual connectivity flags as the first flag in each target dual connectivity flag, the terminal may perform secondary decision by combining signal quality of each reference cell, and select a preferred reference cell with good signal quality from each reference cell.

Optionally, the secondary decision manner may be that the terminal acquires network performance parameters of each reference cell, determines the ranking priority of each reference cell based on each network performance parameter, and then removes the reference cell with the highest priority as the preferred reference cell.

The network performance parameter is a parameter for measuring the signal quality of the reference cell, and the terminal may determine the ranking priority of the reference cell according to the high-low order of the network performance parameter, for example, the terminal may measure the signal power of each reference cell, and determine the ranking priority of the reference cell according to the high-low order of the signal power; for example, the terminal may measure the signal strength value of each reference cell, determine the ranking priority of the reference cells according to the order of the signal strength values, and so on.

The network performance parameter includes, but is not limited to, at least one of Reference Signal Receiving Power (Reference Signal Receiving Power, RSRP) of a Reference cell, received Signal code Power (received Signal code Power, RSCP), Ratio of received chip Signal strength to noise strength (EcIo)/Ratio of Power PER modulation Bit to noise spectral density (EcNo)/Signal-to-noise Ratio (Signal-to-noise Ratio, SNR)/Reference Signal Receiving quality (Reference Signal Receiving quality, RSRQ), Bit Error rate (Bit Error Ratio, BER)/block Error rate (blockerrate, BLER)/Packet Error rate (Packet Error Ratio, PER) of a received Signal, and the like.

Step S309: and if all the target double-connection marks are second marks, determining that the reference cell supporting the double-connection network does not exist in the neighbor cell list, and switching the current resident network cell to the target cell.

Specifically, when each target dual connectivity flag is the second flag, that is, all neighboring cells of the current camping network cell do not support the dual connectivity mode, at this time, the terminal also determines that the reference cell supporting the dual connectivity network does not exist in the neighboring cell list, and then triggers the step of switching the current camping network cell to the target cell.

Further, in some embodiments, the terminal may determine whether at least one target dual connectivity flag exists in each target dual connectivity flag as a third flag, specifically: if a certain cell supports the second network in the dual connectivity network, the dual connectivity flag (EndcFlag) is usually the third flag, for example, taking the second network as an NR network as an example, when a certain cell is deployed in a network, the cell may be understood as only supporting an NR network in the dual connectivity network, and further, in a case that at least one target dual connectivity flag exists in each target dual connectivity flag, the terminal may determine that a reference cell supporting the second network in the dual connectivity network exists in the neighbor cell list, and switch the currently camped cell to the reference cell.

In this embodiment, a terminal determines a target cell to be switched when the terminal is in a dual connectivity mode, and if the target cell supports the dual connectivity network, switches from a current network-camped cell to the target cell, and if the target cell only supports a first network in the dual connectivity network, continues to camp on the current network-camped cell. By combining the network types supported by the target cell and bringing the network types into the cell switching process for reference, the network residence time of the terminal in the dual-connection network can be greatly prolonged, the network quality is improved, the frequent switching of the cell network can be avoided, high-rate services can be continuously provided for users on the terminal based on the dual-connection mode, and the service capability of the terminal is improved; the terminal can quickly determine the network type supported by the target cell through the pre-stored dual-connection cell list, so that cell switching can be quickly carried out based on the network type, the judgment time in the cell switching process is shortened, and the cell switching efficiency is improved; and in the process of switching the terminal cell, if the current network-residing cell can normally provide service to the outside (namely, the cell network-residing condition is met), the current network-residing cell can reside on the cell supporting the dual-connection mode as much as possible instead of being switched to the target cell only supporting the first network (such as an LTE network), so that the service rate of the terminal can be effectively improved, the times of cell switching (such as cell reselection) are reduced, and the power consumption of the terminal in the process of cell switching is reduced.

In addition, the cell switching apparatus and the cell switching method provided in the foregoing embodiments belong to the same concept, and details of implementation processes thereof are referred to in the method embodiments and are not described herein again.

The above-mentioned serial numbers of the embodiments of the present application are merely for description and do not represent the merits of the embodiments.

An embodiment of the present application further provides a computer storage medium, where the computer storage medium may store a plurality of instructions, and the instructions are suitable for being loaded by a processor and executing the cell handover method according to the embodiments shown in fig. 1 to fig. 5, and a specific execution process may refer to specific descriptions of the embodiments shown in fig. 1 to fig. 5, which is not described herein again.

The present application further provides a computer program product, where at least one instruction is stored, and the at least one instruction is loaded by the processor and executes the cell handover method according to the embodiments shown in fig. 1 to fig. 5, where a specific execution process may refer to specific descriptions of the embodiments shown in fig. 1 to fig. 5, and is not described herein again.

Referring to fig. 10, a block diagram of an electronic device according to an exemplary embodiment of the present application is shown. The electronic device in the present application may comprise one or more of the following components: a processor 110, a memory 120, an input device 130, an output device 140, and a bus 150. The processor 110, memory 120, input device 130, and output device 140 may be connected by a bus 150.

Processor 110 may include one or more processing cores. The processor 110 connects various parts within the overall electronic device using various interfaces and lines, and performs various functions of the electronic device 100 and processes data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory 120 and calling data stored in the memory 120. Alternatively, the processor 110 may be implemented in hardware using at least one of Digital Signal Processing (DSP), field-programmable gate Array (FPGA), and Programmable Logic Array (PLA). The processor 110 may integrate one or more of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a modem, and the like. Wherein, the CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for rendering and drawing display content; the modem is used to handle wireless communications. It is understood that the modem may not be integrated into the processor 110, but may be implemented by a communication chip.

The Memory 120 may include a Random Access Memory (RAM) or a read-only Memory (ROM). Optionally, the memory 120 includes a non-transitory computer-readable medium. The memory 120 may be used to store instructions, programs, code sets, or instruction sets. The memory 120 may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a touch function, a sound playing function, an image playing function, etc.), instructions for implementing various method embodiments described below, and the like, and the operating system may be an Android (Android) system, including a system based on Android system depth development, an IOS system developed by apple, including a system based on IOS system depth development, or other systems. The data storage area may also store data created by the electronic device during use, such as phone books, audio and video data, chat log data, and the like.

Referring to fig. 11, the memory 120 may be divided into an operating system space, in which an operating system runs, and a user space, in which native and third-party applications run. In order to ensure that different third-party application programs can achieve a better operation effect, the operating system allocates corresponding system resources for the different third-party application programs. However, the requirements of different application scenarios in the same third-party application program on system resources are different, for example, in a local resource loading scenario, the third-party application program has a higher requirement on the disk reading speed; in the animation rendering scene, the third-party application program has a high requirement on the performance of the GPU. The operating system and the third-party application program are independent from each other, and the operating system cannot sense the current application scene of the third-party application program in time, so that the operating system cannot perform targeted system resource adaptation according to the specific application scene of the third-party application program.

In order to enable the operating system to distinguish a specific application scenario of the third-party application program, data communication between the third-party application program and the operating system needs to be opened, so that the operating system can acquire current scenario information of the third-party application program at any time, and further perform targeted system resource adaptation based on the current scenario.

Taking an operating system as an Android system as an example, programs and data stored in the memory 120 are as shown in fig. 12, and a Linux kernel layer 320, a system runtime library layer 340, an application framework layer 360, and an application layer 380 may be stored in the memory 120, where the Linux kernel layer 320, the system runtime library layer 340, and the application framework layer 360 belong to an operating system space, and the application layer 380 belongs to a user space. The Linux kernel layer 320 provides underlying drivers for various hardware of the electronic device, such as a display driver, an audio driver, a camera driver, a bluetooth driver, a Wi-Fi driver, power management, and the like. The system runtime library layer 340 provides a main feature support for the Android system through some C/C + + libraries. For example, the SQLite library provides support for a database, the OpenGL/ES library provides support for 3D drawing, the Webkit library provides support for a browser kernel, and the like. Also provided in the system runtime library layer 340 is an Android runtime library (Android runtime), which mainly provides some core libraries that can allow developers to write Android applications using the Java language. The application framework layer 360 provides various APIs that may be used in building an application, and developers may build their own applications by using these APIs, such as activity management, window management, view management, notification management, content provider, package management, call management, resource management, and cell switch management. At least one application program runs in the application layer 380, and the application programs may be native application programs carried by the operating system, such as a contact program, a short message program, a clock program, a camera application, and the like; or a third-party application developed by a third-party developer, such as a game application, an instant messaging program, a photo beautification program, a cell switching program, and the like.

Taking an operating system as an IOS system as an example, programs and data stored in the memory 120 are shown in fig. 13, and the IOS system includes: a Core operating system Layer 420(Core OS Layer), a Core Services Layer 440(Core Services Layer), a media Layer 460(Medialayer), and a touchable Layer 480(Cocoa Touch Layer).
