Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. 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.
In the existing NB-IoT system, the terminal initiates the attach procedure as shown in fig. 1, which specifically includes the following steps:
and step 0, the terminal establishes RRC connection with the base station, and the base station distributes cell radio Network Temporary identifiers (C-RNTIs) for the terminal.
Step 1, the terminal sends Non-Access Stratum (NAS) signaling to a Mobility Management Entity (MME): an Attach Request (Attach Request) message, where the message includes an identity of the terminal, an Attach type (e.g., control plane optimization mode, user plane optimization mode, etc.), a data type (IP or non-IP), an Access Point Name (APN), and so on.
The Identity of the terminal may be a fixed Identity, that is, a Unique Identity of the terminal, such as an International Mobile Subscriber Identity (IMSI), or a Temporary Identity, that is, a Temporary Identity allocated to the terminal by a network side device, such as a Globally Unique Temporary UE Identity (GUTI). If the terminal initiates an attachment process for the first time after a Universal Subscriber Identity Module (USIM) is opened, the attach request message usually carries an IMSI, after network attachment is successful, the network side allocates a temporary Identity GUTI to the terminal, the terminal stores the GUTI in the USIM card when powering off, and when the terminal initiates an attachment process for the next time, the attach request message usually carries the GUTI.
Step 2, if the MME acquires the GUTI from the Attach Request message but the GUTI cannot be identified, the MME sends NAS signaling to the terminal: an identity Request (ID Request) message for requesting to acquire IMSI information of a terminal; after receiving the message, the terminal sends NAS signaling to the MME: and an identity Response (ID Response) message, wherein the message carries IMSI information of the terminal.
For example, if the terminal obtains a GUTI allocated by an MME, and initiates an Attach procedure again, because the GUTI includes identifier code information of the MME that allocates the GUTI to the terminal, if an Attach Request or taureq message subsequently sent by the terminal includes the GUTI to another MME, the MME checks whether the MME is connected to the MME having the MME identifier code according to the received identifier code information of the MME in the GUTI, and if so, sends a context Request message to the MME to obtain the context of the terminal, and if not, considers that the GUTI cannot be identified.
And 3, performing authentication between the terminal, the MME and a Home Subscriber Server (HSS), and starting a security mode command process, namely, encrypting the interactive signaling in the process.
And step 4, the MME initiates a Location Update (Location Update) process to the HSS so as to acquire the subscription data information of the terminal.
And step 5, the MME sends a Create Session Request (Create Session Request) message to a Serving GateWay (SGW) and a packet data GateWay (P-GW) to establish a default bearer, so that the transmission of subsequent user plane data is facilitated.
And step 6, the P-GW sends a Create Session Response (Create Session Response) message to the SGW and the MME to indicate that the establishment of the default bearer is successful.
Step 7, if the attachment type requested by the terminal is the control plane optimization mode, the MME sends NAS signaling to the terminal: an Attach Accept (Attach Accept) message to indicate that the terminal is successfully attached, wherein the message carries a GUTI allocated by the MME for the terminal and an Activate Default Bearer Request EPS Bearer Request; if the attachment type requested by the terminal is the user plane optimization mode, the MME further needs to initiate an Evolved radio access Bearer (E-RAB) establishment procedure to the base station.
Step 8, after receiving the Attach Accept message, the terminal establishes a default bearer context of the NAS layer, saves the GUTI and sends an NAS signaling to the MME: attach Complete (Attach Complete) message containing Activate Default Bearer Response EPS Bearer Response.
And then, if the terminal needs to send data to the network side in the control plane optimization mode, through NAS-PDU signaling: the ESM Data Transport message transmits packet Data, the MME transmits the received packet Data to the SGW through S11-U bearing, the SGW transmits the packet Data to the P-GW through S5-U bearing, and the P-GW transmits the packet Data to an external application server. If Data need to be sent to the terminal at the network side, the external application server sends the packet Data to the P-GW, then the P-GW sends the packet Data to the S-GW, the S-GW sends the packet Data to the MME, and the MME sends the packet Data to the terminal through an ESM Data Transport message.
Step 9, after the data transmission is completed, the MME initiates S1 bearer release, triggering the base station to initiate an RRC connection release procedure.
As shown in fig. 1, the process is that the terminal performs attachment after being powered on, and after step 9, if the terminal is not powered off, that is, when the terminal is in an idle state, and if the terminal has packet data to send, after establishing an RRC connection with the base station, through NAS-PDU signaling: the Control Plane Service Request message and the ESM Data Transport message transmit the packet Data to the MME.
In addition, in the existing RRC connection process, if a large number of terminals initiate RRC connections at the same time, so that the base station cannot serve some terminals, the base station sends an RRCConnectionReject message to the terminals, where the message carries a delay wait time extendedWaitTime (unit: second), so that the terminals initiate random access again after waiting for a period of time. However, the mechanism still passively regulates the access behavior of the terminal, and cannot prevent a large number of terminals from initiating random access at the same time.
In order to solve the above technical problem, embodiments of the present invention provide a terminal access control method, which may be applied to an internet of things to actively regulate and control a random access behavior of a terminal, thereby implementing load balancing of a base station.
Referring to fig. 2, a flowchart of a method for controlling access to a terminal according to an embodiment of the present invention is shown, where the method includes the following steps:
The base station configures the time of the next random access for the terminal which has established the RRC connection, so as to realize the active regulation and control of the random access behavior of the terminal, and avoid the base station congestion caused by the fact that a large number of terminals simultaneously initiate the random access and exceed the load capacity of the base station.
Optionally, in step 201, the next random access time configured for the terminal by the base station may be determined jointly by the next activation time and a System Frame Number (SFN) of the next random access, that is, the terminal initiates the random access on a radio Frame corresponding to the SFN indicated by the base station after the next activation time. Accordingly, in the above step 202, the base station transmits the next activation time and the next SFN for random access to the terminal.
The base station can firstly determine an activation period of random access of the terminal, and determine the next activation time of the terminal according to the current time, the activation period and the adjustment time determined according to the load condition of the base station; the base station can determine the SFN when the terminal randomly accesses next time according to the SFN when the terminal randomly accesses this time and the adjustment frame number. Specifically, the next activation time of the terminal may be determined according to formula (1), and the SFN when the terminal randomly accesses next may be determined according to formula (2).
NextActivateTime＝CurrentTime+T+delta_Adjust (1)
NextRaSfnId＝CurrentRaSfnId+offsetSfn (2)
Wherein, NextActivateTime represents the next activation time of the terminal, CurrentTime represents the current time, delta _ Adjust represents the adjustment time, and the units of the parameters in the formula (1) are all seconds(s); NextRaSfnId represents the SFN at the next random access of the terminal, CurrentRaSfnId represents the SFN at the current random access of the terminal, and offsetSfn represents the number of the adjusted frames. The base station may set corresponding delta _ Adjust and offset sfn according to the load condition and the management allocation of the network management device, where the default values of delta _ Adjust and offset sfn may be set to 0.
Optionally, when the base station sends the next activation time and the next randomly accessed SFN to the terminal, the base station may also send the current system time to the terminal at the same time, so as to calibrate the time of the terminal.
Optionally, when the base station configures the activation time of the next random access of the terminal, it may set ((T + delta _ Adjust) × 100) mod1024 to 0, because the time length of each radio frame is 10ms, and the value of the SFN ranges from 0 to 1023, therefore, if the above condition is satisfied, and the offset SFN is set to 0, the SFN corresponding to the time of the next random access may be the same as the SFN of the current random access of the terminal.
Alternatively, the base station may determine an activation period of random access for each accessed terminal, so that the terminal periodically initiates random access according to the activation period. For different terminals, the base station can set corresponding random access activation periods according to different service requirements, for example, a water meter or an electric meter is frequently copied once a month in daily life, and then for the water meter or the electric meter which can automatically report data in the internet of things, the access activation period can be set to be one month.
Optionally, the base station may maintain a corresponding relationship between the terminal identity and the activation period, so that the base station can quickly query the activation period of the terminal according to the terminal identity.
However, in the prior art, the base station does not actively acquire the identity of the terminal. After establishing RRC connection with the base station, the terminal initiates a network attach procedure, and as described above, the terminal sends NAS signaling to the MME: and the Attach Request message and the NAS signaling are sent to the base station by the terminal first and are forwarded to the MME by the base station, and the base station only plays a role of forwarding the signaling and does not analyze information in the signaling.
In the embodiment of the invention, the base station can analyze the NAS signaling and acquire the identity of the terminal from the NAS signaling. As described above, the identity of the terminal carried in the Attach Request message may be a fixed identity, such as an IMSI, or may be a temporary identity, such as a GUTI; the Attach Accept message may also carry the temporary identity of the terminal. The base station can acquire the identity of the terminal by analyzing the NAS signaling and record the identity of the terminal so as to regulate and control the behavior of the terminal subsequently.
Considering that the network management device cannot obtain the temporary identity of the terminal, and the temporary identity of the terminal includes information of the network-side device to which the terminal is accessed, preferably, the base station obtains the fixed identity and the temporary identity of the terminal.
As described above, if the Attach Request message sent by the terminal carries the fixed identity IMSI of the terminal, and the Attach Accept message sent by the MME to the terminal carries the temporary identity GUTI of the terminal, the base station may obtain the fixed identity and the temporary identity of the terminal through the Attach Request message and the Attach Accept message.
If the Attach Request message sent by the terminal carries the temporary identity identifier GUTI of the terminal, after the base station acquires the temporary identity identifier GUTI of the terminal, the base station may construct an NAS signaling: and the terminal returns an ID Response message to the base station after receiving the ID Request message, wherein the message carries the fixed identity IMSI of the terminal, so that the base station can acquire the fixed identity of the terminal.
Through the above improvement over the prior art, the improved terminal-initiated attach procedure is shown in fig. 3. The base station does not only forward the Attach Request message sent by the terminal to the MME any more, but also analyzes the message, acquires the identity of the terminal from the message, and can construct NAS signaling when the Attach Request message only contains a temporary identity GUTI: and the ID Request message is used for acquiring the fixed identity IMSI of the terminal.
The foregoing embodiment is generally a case where the base station acquires the fixed identity and the temporary identity of the terminal through the attach request message when the terminal is powered on and attached.
If the terminal is in an idle state, and the terminal needs to initiate a tracking area update process or initiate a control plane service request, the terminal first initiates random access and establishes RRC connection with the base station, and an RRC connection request RRCConnectionRequest message sent by the terminal to the base station carries a Temporary mobile subscriber Identity (S-Temporary mobile subscriber Identity, S-TMSI), and the S-TMSI is a field information in the GUTI.
Optionally, in step 202, the base station may send the actual RRC connection release signaling of the next random access of the terminal to the terminal. Specifically, the base station may send the next activation time, the next randomly accessed SFN, and the current system time to the terminal by carrying them in the RRC connection release message.
In the above embodiments of the present invention, the fixed Identity IMSI and the Temporary Identity GUTI are used as examples, but the present invention is not limited to this, and other fixed identities, such as an International Mobile Equipment Identity (IMEI), etc., or other Temporary identities, such as a Mobile management entity Temporary Mobile Subscriber Identity (MME-Temporary Mobile Subscriber Identity, M-TMSI), etc., may be used, which is not limited in this respect.
Based on the same technical concept, the embodiment of the invention also provides a base station which is applied to the internet of things and used for realizing the method embodiment.
