Description

Network connection method, device and medium
Technical Field
The disclosure relates to the technical field of wireless communication, and in particular relates to a network connection method, device and medium.
Background
The system message broadcast (system information broadcast) is an important function in the communication system, and mainly provides main information of various access network systems, so that the terminal can conveniently establish wireless connection.
The system information broadcast by the base station equipment is a link for connecting the terminal and the network, and various services and physical processes of wireless communication are completed between the terminal and the base station equipment through the transmission of the system information.
The system messages in a long term evolution (Long Term Evolution, LTE) network include management information blocks (Master Information Block, MIB) and system information blocks (System Information Block, SIBs).
Wherein the MIB message is used to indicate configuration information of downlink bandwidth, single frequency network (Single Frequency Network, SFN) and physical hybrid automatic repeat channel (Physical Hybrid ARQ Indicator Channel, PHICH). The SIB1 message is used to indicate cell access information and scheduling information of other SIBs. Other SIB messages contain different communication parameters. For example: other SIBs include SIB2 through SIB18.SIB2 contains URA information, SIB18 contains neighbor cell PMN information, and so on.
The 5G network includes two types, 5G non-independent Networking (NSA) and independent networking. A 5G non-standalone Networking (NSA) refers to a 5G network deployed using an existing 4G infrastructure.

Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The first protocol referred to in this disclosure is a 4G protocol for accessing a 4G independent network, which may also be referred to as an old 4G protocol, and the second protocol is a 4G protocol for accessing a 4G network in a 5G dependent network, which may also be referred to as a new 4G protocol. A 4G terminal supporting only the first protocol may also be referred to as an old 4G terminal, and a terminal supporting the second protocol may also be referred to as a new 4G terminal.
SIB1 information sent by a 4G base station in the 4G independent networking is a first type of SIB1 information, the first type of SIB1 information is a first protocol compliant SIB1 information, after a terminal supporting the first protocol (or called an old 4G terminal) successfully analyzes the SIB1 information, SIB2 to SIB18 information is analyzed, and the SIB2 to SIB18 information is used for accessing the 4G independent networking.
The SIB1 message sent by the 4G base station in the 5G non-independent network is a second type SIB1 message, where the second type SIB1 message is a SIB1 message conforming to the second protocol, the second type SIB1 message carries a target system information block (the target system information block is a system information block for indicating reselection from the 4G cell to the 5G cell), after receiving the second type SIB1 message, an old 4G terminal that can only parse the first type SIB1 message can only parse the SIB18 message at most, and SIB messages with a sequence number greater than SIB18 are discarded, and at the same time, it is considered that the second type SIB1 message is an illegal SIB1 message, so that the old 4G terminal cannot parse the second type SIB1 message successfully, and cannot access the 4G network in the 5G non-independent network. The old 4G terminal which can only analyze the SIB1 message of the first type can not use the network in the 5G non-independent networking environment.
The number of old 4G terminals is huge, and the old 4G terminals cannot be conveniently upgraded to new version software, so that in order to enable the 5G non-independent networking to be compatible with the old 4G terminals which can only analyze the first type of SIB1 messages, the old 4G terminals can also be accessed to the 4G network in the 5G non-independent networking, and the network connection method is provided in the embodiment of the disclosure. The method is applied to a base station device, which is a 4G base station in a 5G non-independent Networking (NSA). Referring to fig. 1, fig. 1 is a flowchart illustrating a network connection method according to an exemplary embodiment. As shown in fig. 1, the method includes:
Step 101, broadcasting a first type of SIB1 message and a second type of SIB1 message, so that a 4G terminal supporting a first protocol receives and uses the first type of SIB1 message to access a 4G network in a 5G non-independent network, and a 4G terminal supporting a second protocol receives and uses the first type of SIB1 message or the second type of SIB1 message to access a 4G network in a 5G non-independent network;
the first type of SIB1 message is a SIB1 message conforming to a first protocol, the first protocol is a 4G protocol used in 4G independent networking, the second type of SIB1 message is a SIB1 message conforming to a second protocol, and the second protocol is a 4G protocol used in 5G dependent networking.
In an embodiment, the SIB1 message of the first type does not include scheduling information of the target system information block; the second type of SIB1 message including scheduling information of the target system information block; the target system information block is a system information block for indicating reselection from a 4G cell to a 5G cell.
In an embodiment, the first protocol is a 3GPP protocol having a version lower than the 3GPP PDCP r15 protocol among 4G protocols used in the 4G independent networking, and the second protocol is a 3GPP protocol having a version equal to or higher than the 3GPP PDCP r15 protocol.
In the prior art, the 4G base station in the 5G non-independent network broadcasts only the SIB1 message of the second type, so that the old 4G terminal which can only analyze the SIB1 message of the first type cannot access the 4G base station in the 5G non-independent network.
In this embodiment, by improving the 4G base station in the 5G non-independent network, the 4G base station broadcasts the SIB1 message of the first type and the SIB1 message of the second type, so that the SIB1 message of the first type and the SIB1 message of the second type are both broadcasted, and under the condition that the 4G terminal capable of resolving the SIB1 messages of the two types normally accesses the 4G network in the 5G non-independent network, the 4G terminal capable of resolving the SIB1 message of the first type can also successfully access the 4G network in the 5G non-independent network by receiving the SIB1 message of the first type broadcasted under the condition that the SIB1 message of the second type cannot be resolved, so that a large number of 4G terminals capable of resolving the SIB1 message of the first type can access the 5G non-independent network without upgrading mobile phone software, and the 5G non-independent network can be effectively compatible with a large number of 4G terminals capable of resolving the SIB1 message of the first type, thereby improving the compatibility of the network.
Embodiments of the present disclosure provide a network connection method, including the method shown in fig. 1, and: the target system information block is system information block number 24, SIB24. In one embodiment, when the base station device transmits the SIB sequence, SIB24 is located in the last SI window. The values of the system information block valuetags (system info block value tag) of SIB2 through SIB18 in the SIB1 message of the first type remain unchanged.
The scheduling information for SIB2 to SIB18 is included in SIB1 of a first type in the first protocol. When a 4G independent networking is accessed, a 4G terminal (called an old 4G terminal) supporting a first protocol receives a first type SIB1 message broadcasted by the 4G independent networking from a base station of the 4G independent networking, after successfully analyzing the SIB1 message, analyzes SIB2 to SIB18 messages, and accesses the 4G independent networking by using the SIB2 to SIB18 messages.
In the second protocol, a new SIB message, that is, SIB24 message, is defined for LTE, where SIB24 includes information related to cell reselection between 5G systems, such as information of NR frequency points and NR neighbor cells, etc. The second type of SIB1 message contains scheduling information of SIB24, and the second type of SIB1 message notifies the terminal that the SIB24 message can be received at most. The 4G base station in the 5G non-independent networking transmits a second type of SIB1 message, wherein the second type of SIB1 comprises a scheduling message of SIB24 message.
After the 4G terminal supporting the first protocol (called the old 4G terminal) receives the SIB1 message of the second type, since the SIB1 message includes the scheduling message of the SIB24 message, the 4G terminal can only parse the SIB18 message at most, and the SIB message with the sequence number larger than SIB18 is discarded, and at the same time, the SIB1 message of the second type is considered to be an illegal SIB1 message, so that the 4G terminal cannot parse the SIB1 message of the second type successfully, and cannot access the 4G network in the 5G non-independent network by using the SIB1 message of the second type.
Compared with the existing 4G base station in the 5G non-independent networking, the 4G base station in the 5G non-independent networking only broadcasts the second type SIB1 message, and in the embodiment, the 4G base station in the 5G non-independent networking broadcasts the first type SIB1 message besides the second type SIB1 message, so that a 4G terminal (called an old 4G terminal) only supporting a first protocol can also access a 4G network in the 5G non-independent networking, and the 4G terminal (called the old 4G terminal) only supporting the first protocol can normally use the network in an environment of only the 5G non-independent networking.
Embodiments of the present disclosure provide a network connection method, including the method shown in fig. 1, and: in step 101, a SIB1 message of a first type and a SIB1 message of a second type are broadcast, including:
A SIB1 message group is broadcast, the SIB1 message group including at least one SIB1 message of a first type and at least one SIB1 message of a second type. Wherein broadcasting the SIB1 message group includes continuously broadcasting the SIB1 message group.
The SIB1 message group is set in one of the following six manners:
in one mode, the SIB1 message group includes a SIB1 message of a first type and a SIB1 message of a second type in sequence.
In one mode, the SIB1 message is initiated with the SIB1 message of the first type, and the SIB1 message of the first type and the SIB1 message of the second type are polled and broadcasted.
For example: as shown in fig. 2, the broadcasted SIB1 message is in turn: SIB1 message of the first type, SIB1 message of the second type, and so on.
In a second mode, the SIB1 message set includes a SIB1 message of a second type and a SIB1 message of a first type in sequence.
In one mode, the SIB1 message starting with the SIB1 message of the second type polls and broadcasts the SIB1 message of the second type and the SIB1 message of the first type.
For example: as shown in fig. 3, the broadcasted SIB1 message is in turn: SIB1 message of the second type, SIB1 message of the first type, and so on.
In a third aspect, the SIB1 message set includes one or more SIB1 messages of a first type and one or more SIB1 messages of a second type in sequence.
For example: the SIB1 message group includes 2 SIB1 messages of a first type and 1 SIB1 message of a second type in sequence.
As shown in fig. 4, the broadcasted SIB1 message is in turn:
a first type of SIB1 message, a second type of SIB1 message;
a first type of SIB1 message, a second type of SIB1 message;
and so on.
For another example: the SIB1 message group includes 3 SIB1 messages of a first type and 1 SIB1 message of a second type in sequence.
As shown in fig. 5, the broadcasted SIB1 message is in turn:
a first type of SIB1 message, a second type of SIB1 message;
a first type of SIB1 message, a second type of SIB1 message;
and so on.
In a fourth aspect, the SIB1 message set includes one or more SIB1 messages of the second type and one SIB1 message of the second type in sequence.
In a fifth mode, the SIB1 message group includes at least two SIB1 messages of a first type and at least two SIB1 messages of a second type in sequence.
That is, the SIB1 message group sequentially includes M first type SIB1 messages and N second type SIB1 messages, M and N being integers greater than 1.
For example: m and N have values of 2 and 3, respectively; or 3,2; or 3,3; or 3,4; or 4,3, etc.
In a sixth aspect, the SIB1 message group includes at least two SIB1 messages of the second type and at least two SIB1 messages of the first type in sequence.
That is, the SIB1 message group sequentially includes M second type SIB1 messages and N first type SIB1 messages, M and N being integers greater than 1.
For example: m and N have values of 2 and 3, respectively; or 3,2; or 3,3; or 3,4; or 4,3, etc.
The embodiment of the disclosure provides a network connection method applied to a mobile terminal.
Referring to fig. 6, fig. 6 is a flowchart illustrating a network connection method according to an exemplary embodiment. As shown in fig. 6, the method includes:
