Description

Communication method and device
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a communication method and device.
Background
With the rapid development of network technology, a 5th generation mobile communication technology (5G) independent networking (SA) network has become popular. In the prior art, a fourth generation mobile communication technology (4G) base station mainly broadcasts an SIB24 message to enable a 5G SA single-mode terminal or a 5G SA/non-independent Network (NSA) dual-mode terminal under the base station to perform network reselection.
However, since some old version 4G terminals (e.g., R9/R10 terminals) cannot correctly interpret the SIB24 message, the SIB24 message is received and then the SIB24 message is erroneously interpreted, thereby causing a network drop (some or all of the mobile communication networks cannot be used), which may significantly affect the user experience.
Disclosure of Invention
The invention provides a communication method and equipment, which are used for solving the problem of how to avoid the offline of a terminal due to the fact that a reselection message is received. In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the present invention provides a communication method, including: first, type information of a network device is acquired. Then, in a case where the network device is a first type network device, it is determined that the network device stops broadcasting the first reselection message and performs a target operation. The first type network device is a network device of a target communication network stored in a coverage area of the network device, and the network device does not support the target communication network. The first reselection message is used for instructing the terminal to perform cell reselection.
It can be seen that, in the present invention, in the case that the network device is a first type network device (for example, the network device is a 4G base station, and there is no 5G SA network in the coverage area), the network device is instructed to stop broadcasting the first reselection message (for example, SIB24 message). Accordingly, the 4G terminal within the coverage of the type of network device will not receive the first reselection message any longer, because the 4G terminal cannot receive the first reselection message, and the 4G terminal cannot interpret the first reselection message, and even more, it is unlikely that the 4G terminal will go offline because of misinterpretation of the first reselection message. Therefore, the invention solves the problem of how to avoid the offline of the terminal due to the reception of the reselection message. In addition, after stopping broadcasting the first reselection message, the network device in the invention also sends a second reselection message to the terminal supporting the target communication network (for example, a 5G SA network) to instruct the terminal to perform cell reselection.
In a second aspect, the present invention provides a communication device, the device comprising: the device comprises an acquisition unit and a first determination unit. The acquisition unit is used for acquiring the type information of the network equipment. The first determining unit is used for determining that the network device stops broadcasting the first reselection message and executes the target operation when the network device is the first type network device, the first type network device is a network device of a target communication network stored in a coverage area of the network device and the network device does not support the target communication network, and the first reselection message is used for indicating the terminal to execute cell reselection.
In a third aspect, the present invention provides a computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by a communication device, cause the communication device to perform the communication method of the first aspect.
In a fourth aspect, the present invention provides a computer program product comprising instructions which, when run on a communication device, cause the communication device to perform the communication method according to the first aspect.
In a fifth aspect, the present invention provides a communication device, comprising: a processor and a memory, the memory for storing a program, the processor calling the program stored by the memory to perform the communication method according to the first aspect.
Reference may be made to the detailed description of the first aspect and various implementations thereof for specific descriptions of the second to fifth aspects and various implementations thereof in the present disclosure; moreover, the beneficial effects of the second aspect to the fifth aspect and the various implementation manners thereof may refer to the beneficial effect analysis of the first aspect and the various implementation manners thereof, and are not described herein again.
These and other aspects of the invention will be more readily apparent from the following description.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.
The terms "first" and "second" and the like in the description of the present invention and the drawings are used for distinguishing different objects or for distinguishing different processes for the same object, and are not used for describing a specific order of objects.
Furthermore, the terms "comprising" and "having" and any variations thereof as referred to in the description of the invention 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.
It should be noted that in the description of the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or illustrations. Any embodiment or design described as "exemplary" or "such as" in an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the description of the present invention, the meaning of "a plurality" means two or more unless otherwise specified.
As described in the background, partially old version terminals may experience a network drop after receiving the SIB24 message. Whereas the old version of the terminal experienced a talk-around due to the inability to correctly interpret the sibType24-v1530 field in the SIB24 message.
In the prior art, there are mainly two solutions:
scheme 1: the 4G base station alternates sending new and old SIB1 messages. The new SIB1 message carries the sibType24-v1530 field and the old SIB1 message does not carry the sibType24-v1530 field. The scheme can reduce the probability of the problems of the old 4G terminal, but on one hand, the expense of the base station is increased, the time delay from the normal reselection of the 5G terminal from the 4G network to the 5G terminal can be increased, and on the other hand, the possibility of the problems of the old 4G terminal is still existed.
Scheme 2: the sibType24-v1530 field is cancelled in the SIB1 message SIB-Type and instead the SIB24 scheduling related information is issued in a non-critical extension field in the SIB 1. The scheme can avoid the problem of the old 4G terminal and can also ensure that the 5G SA terminal is reselected to the 5G network from the 4G network normally. However, the non-standardized scheme of the scheme has the advantages that on one hand, occupied non-key extension fields cannot play other roles subsequently, on the other hand, existing equipment and existing 5G SA terminals need to change equipment codes again and then upgrade, the influence range is wide, and operability is low.

The following describes a communication method provided by an embodiment of the present invention with reference to the communication system shown in fig. 1 and the communication device 100 shown in fig. 2.
As shown in fig. 3, a communication method provided in an embodiment of the present invention includes:
s301, the communication device 100 acquires the type information of the network device.
Wherein the network devices comprise at least a first type network device and a second type network device. The first type network device is a network device of a target communication network stored in a coverage area of the network device and the network device does not support the target communication network. The second type network device is a network device with no target communication network in the coverage area of the network device.
Illustratively, the network device is a 4G base station and the target communication network is a 5G SA network. The first type network device is a 4G base station for which no 5G SA network exists within the coverage area of the base station. The second type network device is a 4G base station with a 5G SA network in the coverage area of the base station.
In one implementation, the communication device 100 may directly obtain the type information of the network device.
In another implementation, the communication device 100 may first obtain the coverage of the target communication network and the coverage of the network device, and then determine whether there is an overlapping area between the coverage of the network device and the coverage of the target communication network. And then determining the type information of the network equipment according to the judgment result.
For example, the network device is a 4G base station and the target communication network is a 5G SA network. The coverage area of the 4G base station a and the coverage area of the 5G SA network have an overlapping area, and the communication device 100 determines that the 4G base station a is a first type network device.
For another example, the network device is a 4G base station and the target communication network is a 5G SA network. The coverage area of the 4G base station B and the coverage area of the 5G SA network do not have an overlapping area, and the communication device 100 determines that the 4G base station B is a second type network device.
S302, in the case that the network device is the first type network device, the communication device 100 determines that the network device stops broadcasting the first reselection message and performs the target operation.
The first reselection message is used for instructing the terminal to execute cell reselection. For example, the first reselection message may be a SIB24 message.
Specifically, when the network device is a first type network device, the communication device 100 determines that the network device stops broadcasting the first reselection message and, when receiving a target request (e.g., Tracking Area Update (TAU) request) that carries capability information of the terminal and is sent by the terminal, and the request indicates that the terminal supports the target communication network (e.g., the target communication network is a 5G SA network and the request indicates that the terminal is a 5G SA single mode or a 5G SA/NSA dual mode), sends a second reselection message (e.g., RRC connection release message) for instructing the terminal to perform cell reselection to the terminal, and the message (e.g., an Idle Mode Mobility Control Information (IMMCI) field of the message) includes dedicated frequency priority information (the priority information includes frequency point information and frequency point priority information), and the priority of the 5G bins is higher than that of the 4G bins). Correspondingly, after receiving the message, the terminal ignores the frequency point information and the frequency point priority information in the broadcast message, and performs network (cell) reselection according to the frequency point information and the frequency point priority information carried in the IMMCI field.
It is noted that when the network device is a first type network device, it indicates that the target communication network exists in the coverage area of the network device. Therefore, a terminal supporting the target communication network within the coverage of the base station has a need to reselect from the current network to the target communication network. In this case, on one hand, the sending part of the old version terminal is prevented from being disconnected due to the reception of the first reselection message. It is desirable to stop broadcasting the first reselection message. On the other hand, a terminal supporting the target communication network within range of the network device is to be reselected from the current network to the target communication network. A second reselection message needs to be sent to the terminals to cause them to reselect to the target communication network.
In addition, in an implementation manner, in order to support a terminal of a target communication network to reselect to the target communication network more quickly (for example, to reselect a 5G SA single mode or a 5G SA/NSA dual mode from a 4G network to a 5G SA network), different Tracking Area Code (TAC) values may be set for adjacent first type network devices and second type network devices, so that the terminal in an idle state and supporting the target communication network can trigger a TAU procedure when moving to a cell boundary, report a TAU message, and when the TAU completes a re-entry into the idle state, can obtain frequency point information and frequency point priority information through an IMMCI field in an RRC Connection Release, thereby enabling the terminal to perform reselection from a low priority cell to a high priority cell more quickly.
From S301 to S302, it can be seen that, in the embodiment of the present invention, when the network device is a first type network device (for example, the network device is a 4G base station, and there is no 5G SA network in the coverage area), the network device is instructed to stop broadcasting the first reselection message (for example, the SIB24 message). Accordingly, the 4G terminal within the coverage of the type of network device will not receive the first reselection message any longer, because the 4G terminal cannot receive the first reselection message, and the 4G terminal cannot interpret the first reselection message, and even more, it is unlikely that the 4G terminal will go offline because of misinterpretation of the first reselection message. Therefore, the embodiment of the invention solves the problem of how to avoid the offline of the terminal due to the reception of the reselection message. In addition, in the embodiment of the present invention, after stopping broadcasting the first reselection message, the network device further sends a second reselection message to the terminal supporting the target communication network (e.g., a 5G SA network) to instruct the terminal to perform cell reselection.
Referring to fig. 3, as shown in fig. 4, the communication method provided in the embodiment of the present invention may further include:
s303, in the case that the network device is a second-type network device, the communication device 100 determines that the network device stops broadcasting the first reselection message.
It should be noted that, when the network device is a second type network device, it indicates that no target communication network exists in the coverage area of the network device. Therefore, the terminal within the coverage of the base station cannot reselect to the target communication network even if the terminal supports the target communication network, so the network device does not need to broadcast the first reselection message to cause the terminal within the base station to perform cell reselection.
