Detailed Description
For ease of understanding, terms referred to in the present application will be first introduced.
1. System Information (SI)
The system message is cell-level information, i.e. is valid for all terminal devices accessing the cell. The SI is divided into a main system information block (MIB) and a System Information Block (SIB). The MIB includes a limited number of the most important, most commonly used transmission parameters that require additional information from the cell, while the MIB is transmitted on the Physical Broadcast Channel (PBCH). There are many types of SIB types, which may include: system information block 1-narrowband (SIB 1-NB) messages, system information block 2-narrowband (SIB 2-NB) messages, system information block 3-narrowband (SIB 3-narrowband) messages, SIB3-NB) messages, system information block 14-narrowband (SIB 14-narrowband, SIB14-NB) messages, and so forth. The SIB1-NB message not only carries parameters required for the terminal device to access the cell, etc., but also carries scheduling information of other system information block types. The system information blocks except the SIB1-NB can only be transmitted in the same SI message, but cannot be split and mapped into two different SI messages. Multiple system information blocks with the same scheduling requirements may also be encapsulated into the same SI message for transmission together. The protocol provides that the network device broadcasts the system information block in two different ways: the first is to broadcast SIB1-NB through SIB1 message periods, and the second is to broadcast other SIBs than SIB1 through multiple SI message periods.
2. Scheduling of system messages
The transmission format of the SI message is dynamically scheduled, i.e. the transmission of the system message is dynamic and not fixed on a specific subframe. Each transmission opportunity of the SI message is limited to a separate window, also called SI window. The window lengths of all SI messages are equal and can be configured in SIB 1. Within one SI window, the SI message corresponding to the window may be sent multiple times and may be sent in any subframe. The distance between two adjacent SI windows is the period length of the SI, and the period length of each SI is also configured in SIB 1.
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 1 is an architecture diagram of a communication system according to an embodiment of the present application. As shown in fig. 1, the terminal device 101 and the network device 102 corresponding to the cell to be accessed are included. The terminal device 101 is an entity, such as a mobile phone, on the user side for receiving or transmitting signals. A terminal device may also be referred to as a terminal (terminal), a user equipment (ue), a Mobile Station (MS), a Mobile Terminal (MT), etc. The terminal device may be a mobile phone (mobile phone), a wearable device, a tablet computer (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in remote surgery (remote surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in city (city), a wireless terminal in smart home (smart home), an enhanced Machine-Type communication (enhanced Machine-Type communication, eMTC), a long term evolution (IoT) terminal supporting general mobile communication technology, and/or an LTE-capable terminal. The embodiment of the present application does not limit the specific technology and the specific device form adopted by the terminal device.
The oval area in fig. 1 is the coverage area of the cell to be accessed. The network device 102 corresponding to the cell to be accessed is an entity for transmitting or receiving signals on the network side. For example, the network device may be an evolved node b (eNB), a transmission point (TRP), a next generation base station (gNB) in a New Radio (NR) system of 5G, a base station in another future mobile communication system, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices.
It should be noted that the technical solution of the embodiment of the present application can be applied to the following communication systems: LTE, eMTC, NB-IoT, fifth generation (5th generation,5G) mobile communication. Optionally, the method of the embodiment of the present application may also be applied to various future communication systems, such as a 6G system or other communication networks.
It should be further noted that the system messages mentioned in the embodiments of the present application may be LTE system messages, eMTC system messages, NB-IoT system messages, or system messages in other new mobile communication systems.
In the exception handling method shown in fig. 1, the flow of exception handling mainly includes: firstly, if the terminal equipment 101 determines that the first system message broadcasted by the network equipment 102 corresponding to the cell to be accessed needs to be read, determining the position information of the target subframe; the terminal equipment 101 reads the first system message according to the position information; if the terminal device reads the first system message, the terminal device 101 initiates an access flow to the network device 102 corresponding to the cell to be accessed.
By the above exception handling method, when an exception occurs in the process of reading the system message, the terminal device 101 directly initiates an access flow to the network device 102 corresponding to the cell to be accessed, which is beneficial to shortening the network residence time delay of the terminal device, thereby improving the user experience.
The following describes an exception handling method provided by the present application in detail.
Referring to fig. 2, fig. 2 is a flowchart illustrating an exception handling method according to an embodiment of the present disclosure. The exception handling method may be implemented by the terminal device 101 shown in fig. 1, or may be implemented by a chip in the terminal device 101; as shown in fig. 2, the exception handling method includes, but is not limited to, the following steps 201 to 203, and the method shown in fig. 2 is described by taking the application to the terminal device 101 as an example.
S201, if the terminal equipment determines that the first system message broadcasted by the cell to be accessed needs to be read, determining the position information of the target subframe.
Specifically, after the terminal device completes the cell search process, it may be determined that the terminal device needs to read the first system message broadcasted by the cell to be accessed according to the system message.
The system messages are carried in subframes, and in order to read the first system message, the position information of one subframe (such as a target subframe) can be determined, so that the first system message can be read according to the position information. In an embodiment of the present application, a method for determining target subframe location information may include determining location information of a subframe in which a first system message is located according to a scheduling information period, where the scheduling information period includes a period length of an SI. The terminal device may decode the period length of each subsequent SI from SIB 1.
Wherein the first system message may include the SIB 14-NB.
S202, the terminal equipment reads the first system message according to the position information.
And reading the first system message according to the position information of the target subframe obtained in the step S201.
S203, if abnormity occurs in the process of reading the first system message, the terminal equipment initiates an access flow aiming at the cell to be accessed.
The case where an abnormality occurs in the process of reading the first system message may include any one of the following: first, reading the first system message according to the location information of the target subframe fails. In other words, the position information of the subframe where the first system message is located is the same as the position information of the target subframe, that is, the determined position information of the target subframe is correct, and an error occurs in the process of reading the first system message, resulting in a reading failure. Second, the position information of the subframe where the first system message is located is different from the position information of the target subframe, that is, the determined position information of the target subframe does not carry the first system message.
In the prior art, when reading of the first system message fails, the first system message may be read again in the next first system message reading period, and if the reading fails in all the preset N first system message reading periods, the terminal device searches for a new network. Although an abnormality occurs in the process of reading the first system message by the terminal device, actually, the cell to be accessed allows the terminal device to access, and then repeatedly reading the first system message by adopting the prior art increases the network residence time delay and the power consumption. Therefore, if an abnormality occurs in the process of reading the first system message by the terminal device, the cell to be accessed may be defaulted to have no access restriction, and the terminal device directly initiates an access flow for the cell to be accessed.
In the above embodiment, when an abnormality occurs in the process of reading the first system message, the terminal device directly initiates the access flow to the cell to be accessed, which can avoid re-reading the first system message and searching for and selecting a network, thereby effectively shortening the network residence time delay.
Referring to fig. 3, fig. 3 is a flowchart of another exception handling method provided in this embodiment of the present application, where the exception handling method shown in fig. 3 may be implemented by the terminal device 101 shown in fig. 1, or may be implemented by a chip in the terminal device 101; as shown in fig. 3, the exception handling method includes, but is not limited to, the following steps 301 to 307:
s301, the terminal device receives a second system message broadcasted by the cell to be accessed, wherein the second system message carries first indication information, and the first indication information is used for indicating whether the terminal device needs to read the first system message.
The second system message may include a master information block-narrowband (MIB-NB).
S302, the terminal device determines that the first system message needs to be read according to the first indication information.
The terminal device determines that the first system message needs to be read according to the first indication information, and determines whether the cell to be accessed broadcasts the first system message in order to successfully read the first system message. Optionally, if the terminal device determines that the terminal device does not need to read the first system message according to the first indication information, step S303 and the subsequent steps may not be executed.
S303, the terminal equipment receives a third system message broadcasted by the cell to be accessed, wherein the third system message carries second indication information, and the second indication information is used for indicating whether the cell to be accessed broadcasts the first system message;
wherein the third system message may include the SIB 1-NB.
S304, the terminal equipment determines the cell to be accessed to broadcast the first system message according to the second indication information.
The terminal equipment determines that the terminal equipment needs to read the first system message according to the first indication information, and determines that the cell to be accessed broadcasts the first system message according to the second indication information, namely determines that the first system message broadcasted by the cell to be accessed needs to be read. To read the first system message, location information of the target-subframe may be determined so that the first system message is read according to the location information.
S305, the terminal equipment determines the position information of the target subframe.
S306, the terminal equipment reads the first system message according to the position information.
S307, if abnormity occurs in the process of reading the first system message, the terminal equipment initiates an access flow aiming at the cell to be accessed.
It should be noted that, the execution process of steps S305 to S307 may refer to the specific description in steps S201 to S203 in fig. 2, and is not described herein again.
In the above embodiment, if an abnormality occurs in the process of reading the first system message, the access flow for the cell to be accessed is initiated, and re-reading of the system message and network searching and selection can be avoided, so that the network residence time delay is effectively shortened, and the power consumption is reduced.
