Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.
Referring to fig. 1, a method for a 5G terminal to continuously camp on a base station in a core-network-free scenario is provided, including: the base station receives a random access request initiated by the terminal and replies a random access request response message to the terminal, wherein the random access request is initiated to the base station without the core network when the terminal measures the signal quality of the base station and meets the cell reselection condition; after receiving an RRC connection establishment completion message sent by a terminal, a base station starts a first timer, wherein the period of the first timer is smaller than the period of a second timer in the terminal, and the RRC (Radio Resource Control) connection establishment completion message is sent to the base station by the terminal according to a random access connection request response message replied by the base station and is sent to the base station after the RRC connection establishment with the base station is completed according to the RRC connection establishment response message replied by the base station; and periodically changing a TAC (Tracking area code of cell served by neighbor Enb) according to a first timer, updating the system message, and periodically initiating a new registration request to the base station when the terminal monitors the updated system message.
It can be understood that, referring to fig. 2, fig. 2 is an application scenario of the embodiment of the present invention, and in a coreless network scenario, a basic principle of implementing a 5G terminal to continuously camp on a base station is as follows: the 5G base station 1 is connected with a core network, and the 5G base station 2 is not provided with the core network. The terminal resides in the coverage area of the 5G base station 1 and is in a normal communication state. When the signal quality of the terminal residing in the base station at present is lower than the same-frequency measurement threshold or the different-frequency measurement threshold, the same-frequency measurement or the different-frequency measurement can be carried out. And when the measured adjacent cell signals meet the cell reselection conditions, cell reselection is carried out, a random access process is initiated, and the 5G base station 2 is accessed. Since the 5G base station 2 has no core network and does not respond to the registration request of the terminal, the base station periodically changes the TAC, updates the system message, prompts the terminal to initiate a new registration request dlinformation transfer (registration request) according to the periodically updated system message, and ensures that the terminal continuously resides in the base station 2.
In the embodiment of the invention, after the 5G terminal is accessed to the base station without the core network, the base station can not respond to the registration request of the terminal, so that the base station can periodically change the TAC and update the system information, and the terminal periodically initiates a new registration request to the base station according to the updated system information, thereby ensuring that the terminal can continuously reside in the base station in the scene without the core network.
As a possible implementation manner, after the terminal reselects the 5G base station 2, the RRC connection establishment procedure is completed, the base station 2 issues terminal identifier query information to the terminal, and after receiving the information, the terminal reports the terminal identifier IMSI (International Mobile Identity) to the base station, so that the base station can obtain the IMSI of the access terminal in a coreless network scenario.
Referring to fig. 3, a method for a 5G terminal to continuously camp on a base station in a core-network-free scenario is provided, including: when the signal quality of the base station measured by the terminal meets the cell reselection condition, a random access request is initiated to the base station without the core network; when receiving a random access request response message of a base station, a terminal sends an RRC connection establishment request to the base station, establishes RRC connection with the base station according to the RRC connection establishment request response message replied by the base station, and sends an RRC connection establishment completion message to the base station; and periodically initiating a new registration request to the base station according to the monitored periodically updated system message, wherein the periodically updated system message is that when the base station receives an RRC connection establishment completion message sent by the terminal, a first timer is started, the TAC is periodically changed according to the first timer, and the system message is updated.
It can be understood that, when the terminal meets the cell reselection condition by measuring the signal quality of the currently camped base station and the signal quality of the neighboring cell base station, the terminal initiates a random access request to the neighboring cell base station without the core network. Because the neighboring cell has no core network and cannot respond to the registration request of the terminal, after the terminal establishes RRC connection with the base station, the base station starts a first timer and periodically changes the TAC according to the first timer to update the system message. The terminal monitors the periodic system updating message and periodically initiates a new registration request to the base station, so as to ensure that the terminal continuously resides in the base station without the core network.
As a possible implementation manner, when the terminal measures that the signal quality of the base station satisfies the cell reselection condition, initiating a random access request to the base station without the core network includes: when a current resident base station signal of a terminal in an RRC idle state is lower than a same-frequency measurement threshold or a different-frequency measurement threshold, starting same-frequency measurement or different-frequency measurement, measuring a base station signal of an adjacent cell, and when the base station signal of the adjacent cell meets a cell reselection condition, initiating a random access request to the base station of the adjacent cell, wherein the base station of the adjacent cell is a coreless network base station; when the terminal is in a power-off state, a random access request is initiated to the base station with the strongest signal after the terminal is powered on.
It can be understood that, when the terminal measures the signal quality of the coreless network base station and meets the reselection condition, the base station is re-accessed, the random access process is completed, and the RRC connection is established with the base station.
As a possible implementation manner, after the terminal sends the RRC connection setup complete message to the base station, the method further includes: receiving a terminal identification query message sent by a base station, and returning an International Mobile Subscriber Identity (IMSI) of a corresponding terminal to the base station; the terminal identifier query request is sent to the terminal after the base station receives an RRC connection setup completion message sent by the terminal.
It can be understood that, after the RRC connection between the terminal and the base station is completed, the base station sends the terminal identifier query message to the terminal, and when the terminal receives the terminal identifier query message sent by the base station, the terminal returns the IMSI of the terminal to the base station.
The method provided by the embodiment of the invention is described in detail as follows:
and a, the terminal completes the processes of cell reselection and random access.
The terminal in the RRC idle state resides in the base station 1, and when the terminal measures that the cell signal of the base station 1 is lower than the co-frequency measurement threshold or the inter-frequency measurement threshold, the terminal starts to perform the co-frequency measurement or the inter-frequency measurement. And when the signal quality of the base station 2 measured by the terminal meets the reselection condition, reselecting the access base station 2 and finishing the random access process. The random access process mainly comprises that the terminal initiates a random access request RandomAccess preamble, and the base station replies a random access response message RandomAccess response.
And step b, the terminal initiates an RRC connection establishment request.
And after receiving the random access response message replied by the base station, the terminal initiates an RRCConnectionSetupRequest, and the RRC Connection SetuP Request is an RRC Connection establishment Request.
And step c, the base station responds to the RRC connection establishment.
And after receiving the RRCConnectionSetupRequest, the base station sends RRCConnectionSetup to the terminal, and the RRCConnectionSetup establishes response for RRC connection.
And d, the terminal replies the RRC connection establishment completion and starts a T3510 timer, wherein the T3510 timer is the second timer.
After receiving the RRC Connection Setup message, the terminal is in the RRC _ CONNECTED state, replies an RRCConnectionSetupComplete message to the base station, where the RRCConnectionSetupComplete message is an RRC Connection Setup complete message carried in a REGISTRATION REQUEST.
The terminal starts a T3510 timer after transmitting an RRC ConnectionSetupComplete message. And stopping the timer when receiving a system updating message of the base station before the timer is overtime. After the timer is overtime, the terminal does not receive the system update message replied by the base station, and the terminal enters an exception handling process and does not stay in the base station continuously.
Under the scene of a coreless network, the 5G terminal and the base station cannot complete the bidirectional authentication process. Therefore, the base station does not respond to the registration request message. In order to ensure that the terminal continuously resides in the base station, the base station needs to change the tac (tracking Area code), update the system message, and trigger the UE to send a new registration request before the timer expires. Specifically, after receiving the RRCConnectionSetupComplete message, the base station starts a TAC change timer, which is the first timer.
Wherein, the TAC changes the timer, namely after the timer is overtime, TAC adds 1, change TAC; the timer is less than the T3510 timer. And after the TAC change timer is overtime, the TAC is changed, and system message updating is triggered. After receiving the system message update, the terminal triggers the next registration request and restarts the T3510 timer.
And e, the base station sends a terminal identification query request.
And after the RRC connection between the terminal and the base station is completed, the base station sends terminal identification query information to query the terminal identification.
And f, the terminal replies a terminal identification inquiry response message.
And after receiving the terminal identification query information sent by the base station, the terminal sends the terminal IMSI identification to the base station.
And step g, the base station sends a system message and updates the TAC.
And when the TAC change timer is overtime, the TAC is changed and the system information is updated.
And h, the terminal sends a registration request message.
And (4) the terminal receives the system message after updating the TAC and initiates a new registration request, the base station restarts the TAC change timer after receiving the registration request message, the processes of the step (e), the step (f), the step (g) and the step (h) are repeated, the new registration request is periodically initiated to the base station, and the terminal is ensured to be continuously resident in the base station.

the first receiving module 41 is configured to receive a random access request initiated by a terminal, and reply a random access request response message to the terminal, where the random access request is initiated to a base station without a core network when the signal quality of the base station measured by the terminal meets a cell reselection condition.
