Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1, the network search method according to the embodiment of the present invention is applied to a network search pointing device. The network search indication device may be an application server, a network side device, or the like. The method comprises the following steps:
wherein the network search indication comprises: application layer messages, signaling or global system for mobile communications GSM system broadcast information. By the network search indication, the NB-IoT dual-mode or multi-mode terminal can initiate network search.
In an embodiment of the present invention, the application server may send the network search indication to the NB-IoT dual mode or multi mode terminal as follows.
Assume that at the beginning of network construction, some NB-IoT network has not been deployed. After a terminal in the place is powered on, a Global System for Mobile communication (GSM) cell is selected according to a normal PLMN (Public Land Mobile Network) search process, and then the terminal always resides in the GSM cell as long as the GSM cell satisfies the residence.
Then, when it is monitored that the NB-IoT network is ready, NB-IoT cell information can be obtained, and the terminal is further instructed to start network search. Specifically, in the embodiment of the present invention, the application server may obtain the NB-IoT cell information by:
(1) the application server receives NB-IoT cell information sent by the operator.
(2) And the application server receives NB-IoT cell information reported by a first NB-IoT dual-mode or multi-mode terminal in the NB-IoT dual-mode or multi-mode terminal. The first NB-IoT dual or multi-mode terminal may be any NB-IoT dual or multi-mode terminal.
In the method, NB-IoT dual-mode or multi-mode terminals respectively set respective timers, NB-IoT search is carried out when the timers are overtime, and after NB-IoT cell signals which can reside are searched, the searched NB-IoT cell information is reported to an application server; otherwise, the timer is reconfigured.
Specifically, the timer configuration method comprises the following steps: an evenly distributed random number X is generated from 0 to X, and the time duration of the timer is X seconds. Here, X is the number of seconds corresponding to a long time such as 1 year or 5 years.
The method can realize quick response of the whole region to the NB-IoT network deployment situation through extremely low background search frequency. After one terminal discovers NB-IoT signals, the application server controls all terminals in the whole region to initiate different system network searching. If the number of the terminals in a certain area is set to be N, the mathematical expectation of the terminal to the NB-IoT network deployment response delay in the whole area is X/N, and if N is 10000 and X is one year, the mathematical expectation of the response delay is only 0.9 hour; for a single terminal, the network is searched every half year, and the increased power consumption is almost negligible.
(3) The application server sends network searching configuration information to the NB-IoT dual-mode or multi-mode terminal, so that the NB-IoT dual-mode or multi-mode terminal searches an NB-IoT cell according to the network searching configuration information, and then the application server receives NB-IoT cell information reported by a first NB-IoT dual-mode or multi-mode terminal in the NB-IoT dual-mode or multi-mode terminal.
Specifically, the application server issues a command to set a network search Period and a network search offset for each terminal. For the terminal i, starting the inter-system network searching process when the (current time mod Period) is equal to offset. The current time may be the time at which an embodiment of the invention is performed. By configuring proper network searching offset, the network searching time of the terminal in a certain area is uniformly divided in the whole network searching period. Specifically, Period may be configured for a longer time of 1 year, 5 years, and the like; let the number of the certain terminal be N, and number each terminal sequentially be 0.. N-1, then the network search offset Offseti of each terminal is i (Period/N).
In the embodiment of the present invention, a network side device (e.g., a base station, etc.) may send a network search indication to an NB-IoT dual-mode or multi-mode terminal by using signaling. The signaling is a different system indication search message sysNotifyInterRatSearch, and the signaling may include information about a different system cell.
In the embodiment of the present invention, the network-side device (e.g., a base station, etc.) may further send a network search indication to the NB-IoT dual-mode or multi-mode terminal by using a GSM system broadcast message. Specifically, a network search indication bit is set in the GSM system broadcast message, and the network search indication bit is used to indicate an NB-IoT dual-mode or multi-mode terminal to perform inter-system network search.
For example, in the embodiment of the present invention, 1 bit (referred to as NB _ IoT _ Indicator) is added to certain GSM system broadcast information (e.g., SI Type 3), and when the bit is 1, it indicates that an NB-IoT cell exists around the GSM cell, otherwise, it indicates that an NB-IoT cell does not exist around the GSM cell. After a terminal at the place is started, a GSM cell is selected according to a normal PLMN search flow, and then an NB-IoT network search flow is started when an NB _ IoT _ Indicator is detected to be 1 from an SI Type 3.
For another example, in the embodiment of the present invention, a certain bit (for example, PSI3_ CHANGE _ MARK is reduced from 2 bits to 1 bit, and another bit is used as NB _ IoT _ Indicator) in the GSM system broadcast information (for example, SI Type 3) may be multiplexed. When the bit (NB _ IoT _ Indicator) is 1, it indicates that an NB-IoT cell exists around the GSM cell, otherwise, it indicates that no NB-IoT cell exists around the GSM cell. After a terminal at the place is started, a GSM cell is selected according to a normal PLMN search flow, and then an NB-IoT network search flow is started when an NB _ IoT _ Indicator is detected to be 1 from an SI Type 3.
In this way, the interoperability of GSM and NB-IoT is introduced to a certain extent with the assistance of the GSM network, and only one bit needs to be added or modified, which is simple to implement.
In the embodiment of the invention, the NB-IoT dual-mode or multi-mode terminal carries out inter-system network search according to the network search indication of the network search indication equipment, so that the network search is not required to be carried out periodically like the prior art, therefore, by utilizing the scheme of the embodiment of the invention, compared with the prior art, the power consumption of the NB-IoT dual-mode or multi-mode terminal in the network search process is reduced, and the implementation is simple.
As shown in fig. 2, the network searching method of the embodiment of the present invention is applied to an NB-IoT dual-mode or multi-mode terminal, and includes:
Wherein the network search indication comprises: application layer messages, signaling, or GSM system broadcast information.
correspondingly, the application layer message and the signaling GSM system broadcast information are received, and the network search is carried out according to the indication.
For example, taking a GSM system broadcast message as an example, a terminal may read a network search indication bit in the GSM system broadcast message, and perform inter-system network search according to the network search indication when the network search indication bit indicates that network search is required.
In the embodiment of the invention, the NB-IoT dual-mode or multi-mode terminal can also acquire configuration information, perform network search according to the configuration information to acquire NB-IoT cell information, and send the NB-IoT cell information to the network search indicating equipment, so that the network search indicating equipment sends the NB-IoT cell information to the NB-IoT dual-mode or multi-mode terminal. The network search indication device may be an application server, a network side device, or the like.
Specifically, here, the NB-IoT dual-mode or multi-mode terminal may obtain the configuration information as follows:
(1) the method comprises the steps of obtaining the timing duration of a timer, starting the timer, and carrying out network search to obtain NB-IoT cell information after the timing duration of the timer exceeds the timing duration.
In the method, NB-IoT dual-mode or multi-mode terminals respectively set respective timers, NB-IoT search is carried out when the timers are overtime, and after NB-IoT cell signals which can reside are searched, the searched NB-IoT cell information is reported to an application server; otherwise, the timer is reconfigured.
Specifically, the timer configuration method comprises the following steps: an evenly distributed random number X is generated from 0 to X, and the time duration of the timer is X seconds. Here, X is the number of seconds corresponding to a long time such as 1 year or 5 years.
The method can realize quick response of the whole region to the NB-IoT network deployment situation through extremely low background search frequency. After one terminal discovers NB-IoT signals, the application server controls all terminals in the whole region to initiate different system network searching. If the number of the terminals in a certain area is set to be N, the mathematical expectation of the terminal to the NB-IoT network deployment response delay in the whole area is X/N, and if N is 10000 and X is one year, the mathematical expectation of the response delay is only 0.9 hour; for a single terminal, the network is searched every half year, and the increased power consumption is almost negligible.
(2) And obtaining a network searching period and network searching offset sent by the network searching indication equipment, performing a surplus operation on the current time and the network searching period, and if the result of the surplus operation is equal to the network searching offset, performing network searching to obtain NB-IoT cell information.
Specifically, the application server issues a command to set a network search Period and a network search offset for each terminal. For the terminal i, starting the inter-system network searching process when the (current time mod Period) is equal to offset. The current time may be the time at which an embodiment of the invention is performed. By configuring proper network searching offset, the network searching time of the terminal in a certain area is uniformly divided in the whole network searching period. Specifically, Period may be configured for a longer time of 1 year, 5 years, and the like; let the number of the certain terminal be N, and number each terminal sequentially be 0.. N-1, then the network search offset Offseti of each terminal is i (Period/N).
In the embodiment of the invention, the NB-IoT dual-mode or multi-mode terminal carries out inter-system network search according to the network search indication of the network search indication equipment, so that the network search is not required to be carried out periodically like the prior art, therefore, by utilizing the scheme of the embodiment of the invention, compared with the prior art, the power consumption of the NB-IoT dual-mode or multi-mode terminal in the network search process is reduced, and the implementation is simple.
The NB-IoT/GSM dual mode terminal is taken as an example for explanation as follows.
For example, at the beginning of network construction, some NB-IoT networks have not been deployed. After the NB-IoT/GSM terminal of the location is started, the GSM cell is selected according to a normal PLMN search flow, and then the terminal always resides in the GSM cell as long as the GSM cell meets the requirement of residence. Each terminal of the place is respectively provided with a timer, the timer is overtime to carry out NB-IoT search, and after NB-IoT signals which can be resided are searched, cell information is reported to an application server through IP data; otherwise, the timer is reconfigured. Specifically, the timer configuration method here is as follows: an evenly distributed random number X is generated from 0 to X, and the time duration of the timer is X seconds. Here, X is the number of seconds corresponding to 1 year, 5 years, or the like. And after receiving the NB-IoT network ready signal, the application server informs the terminal of NB-IoT cell information by issuing IP data. And the terminal starts the NB-IoT inter-system network searching after receiving the NB-IoT cell information issued by the application layer, and completes the subsequent cell selection process.
For another example, in the initial stage of network construction, the NB-IoT network is not deployed in a certain place, and after the terminal is turned on, the terminal selects the GSM cell according to the normal PLMN search flow, and then as long as the GSM cell satisfies the residence, the terminal resides in the GSM cell all the time without searching NB-IoT signals. After the NB-IoT network in the area is constructed, a manager triggers the GSM core network to send a sysNotifyInterRatSearch message to an Internet of things terminal using the GSM network in the area through manual operation, wherein the message comprises information such as NB-IoT frequency points, cell IDs and the like. After receiving the sysNotifyInterRatSearch message, the terminal searches NB-IoT signals according to information such as NB-IoT frequency points, cell IDs and the like contained in the message, and selects an NB-IoT cell if the residence condition is met. It should be noted that the message is also received for GSM single mode internet of things terminals, but since it does not support NB-IoT, this type of terminal can directly ignore the message.
