Abstract

Provided are a tracking area updating device, system and method. A user equipment, as a tracking area updating device, acquires first information, wherein the first information is used for determining a waiting time; if it is determined that a tracking area updating process needs to be performed, a processing module is in accordance with the first information, and the user equipment determines the waiting time; and after waiting for the waiting time, the user equipment sends a tracking area updating request message to a core network device as the tracking area updating device. On this basis, for a UE moving at a high speed, such as a UE performing communications under the condition of high speed railways, each UE is configured to wait for a certain time before performing a tracking area updating process, thereby avoiding a signalling storm caused when a UE intensively triggers a tracking area updating process within a short time and thus avoiding network congestion.

Description

Tracking area updating device, system and method

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a tracking area updating apparatus, system, and method.

Background technique

In the existing standard, the user equipment (User Equipment, UE for short) opens an opportunity to initiate an attach process to the network. FIG. 1 is a schematic diagram of an attach process provided by the prior art. Referring to FIG. 1, in the attaching process, The UE and the Mobility Management Entity (MME) perform an interaction procedure of an Attach Request/Attach Accept/Attach Complete, and the MME carries the tracking area in the attach confirmation message. A list of the Tracking Area Identity (TAI) is given to the UE. When the UE is in the idle state, the MME needs to send a paging message to the UE based on the TAI list information, and generally sends a paging message to the UE in all the TAIs included in the TAI list and all the cells included in each TAI. Message. 2 is a schematic flowchart of a paging message provided by the prior art. Referring to FIG. 2, the first paging (paging) message sent by the MME to the evolved Node B (abbreviated as eNB) carries the TAI. The eNB sends a second paging message of the air interface to the UE in the cell belonging to the TAI list, wherein the first paging message sent by the MME to the eNB is different from the content of the second paging message sent by the eNB to the UE.

The TAI list of the UE is a tracking area range composed of a certain number of cells. When moving within the range, the network can find the UE by sending a paging message. When the UE moves out of the tracking area, that is, when the reselected cell is not in the tracking area, the UE can also page the UE when there is downlink service, that is, the TAU process is performed, and FIG. 3 is the existing The schematic diagram of the TAU process provided by the technology, referring to FIG. 3, obtains the Tracking Area Code (TAC) of the cell from the cell broadcast message when the UE is in the idle state, and triggers the tracking if the TAC does not belong to the TAI list. Tracking Area Update process TAU. As shown in FIG. 3, the TA update process is performed between the UE and the MME, and the specific interaction includes: tracking area update request/tracking area update confirmation/tracking area update completion. The process is used by the MME to obtain the latest tracking area information of the UE, and the UE obtains the updated information from the MME. TAI list. In this way, the MME can still page to the UE. Further, the range of coverage of the TAI list is related to the signaling load. When the TAI list covers a large range, the chance of triggering the TAU process is reduced, but if paging is required, the required paging signaling overhead is Will increase. Conversely, when the range covered by the TAI list is small, the chance of triggering the TAU process increases, but at this time, the paging signaling overhead of the paging UE is reduced. In general, a TAI list of suitable coverage is set based on the signaling load.

The industry is currently discussing communications in high-speed rail scenarios. High-speed rails are generally covered by wireless private networks. And the speed of the current high-speed rail can reach 350 km / h, but when the terminal moves across the cell at such a high speed, the existing TAU process trigger mechanism will enable a large number of terminals in the high-speed rail to densely trigger TAU in a short time. The process generates a signaling storm, causing network congestion.

FIG. 24 is a schematic flowchart of a method for updating a tracking area according to an embodiment of the present invention. The executor of the method is a user equipment UE, and the UE may adopt the structure shown in any one of 4 to 10, or adopt FIG. The structure shown in any one of FIG. Specifically, the UE may be: a smartphone, a notebook, a tablet, a Machine Type Communication (MTC) UE, etc. Referring to FIG. 24, the method includes the following steps:

Step 100: The user equipment UE acquires first information, where the first information is used to determine a waiting time.

Step 101: If the UE determines that a tracking area update process needs to be performed, determining the waiting time according to the first information.

Step 102: After the UE waits for the waiting time, the UE sends a tracking area update request message to the core network device.

Specifically, after the UE waits for the waiting time, the UE may send the tracking area update request message immediately, or may send the tracking area update request message again after a period of time.

According to the tracking area update method provided by the embodiment of the present invention, the first information is obtained by the user equipment UE, where the first information is used to determine a waiting time; and if the UE determines that the tracking area update process needs to be performed, according to the first information Determining the waiting time; after the UE waits for the waiting time, the UE sends a tracking area update request message to the core network device.

The resulting signaling storm prevents network congestion.

Further, the UE sends a tracking area update request message to the core network device, where the UE requests a lower layer (for example, an RRC layer) to establish an RRC connection, and after the connection is established, to the core network device. Send a tracking area update request message.

Further, for step 100, there may be multiple feasible implementations, and several possible implementations are given below:

Manner 1: The UE receives a broadcast message or a multicast message or a group message sent by the network side device, where the broadcast message or the multicast message or the group message includes the first information.

Manner 2: The UE receives a core network message sent by a core network device, where the core network message includes the first information.

Specifically, the core network message may be an attachment acknowledgement message, an authentication response message, a Detach Accept message, a Tracking Area Update Accept, and other core network messages. .

Manner 3: The UE acquires the first information preset in the UE storage medium.

For the first mode, the broadcast message may be System Information Block (SIB) or SIB2. The network side device may be an access device of the cell, such as a cell, a base station, an evolved Node B (eNB), a relay device, etc., when the UE moves to the cell corresponding to the network side device at a high speed, The network side device sends the above broadcast message or multicast message or group message to the UE. For the second mode, the core network device may be an MME, and the core network device may configure the first information to the UE by using a core network message when the UE performs an attach process, and optionally, for the manner The UE needs to carry the UE type information or the UE capability information in an attach request message sent to the MME, to indicate that the UE is a high-speed mobile UE. Or have the ability to move at high speed.

It should be noted that, for the step 100, the foregoing three possible implementation manners are only illustrated as an example, and the implementation manner of the step 100 is not limited to the foregoing three types.

Optionally, there may be multiple implementation forms of the waiting time, which are illustrated by specific examples below:

The waiting time is a timing value of the timer. Correspondingly, the UE is provided with a timer.

Then a specific implementation of step 102 is:

Step 102a: The UE starts the timer, and sends the tracking area update request message to the core network device after the timing value of the timer expires.

Optionally, in the step 101 of the foregoing embodiment, regarding how to determine the waiting time, there may be multiple implementation manners. The following provides a description of several possible implementation manners:

Manner 1: The first information is a first time value, and the UE randomly selects a value as the waiting time from zero to the first time value.

Manner 2: The first information is a second time value and a third time value, and the UE randomly selects a value as the waiting time from the second time value to the third time value .

Manner 3: The first information is at least one parameter value; and the UE performs a function operation with the at least one parameter value as an independent variable, and the obtained value is the waiting time.

For mode 3, one possible mode is: wait time = random(0,1)* parameter value, where random(0,1) is a random number from 0 to 1. If it needs to be explained, mode 3 can also be used. Other functions are operated, so the embodiment of the present invention does not limit the specific form of the function operation, and is not listed here.

Specifically, in order to further avoid the signaling storm caused by multiple UEs moving at high speed simultaneously triggering the tracking area update process, one solution is to configure a different waiting time for each UE, and the foregoing third implementation manner of step 101 In the middle, when the UE obtains the first information, A set of time values is obtained, and a value of each time value obtained by each UE is randomly selected as the waiting time. It should be noted that the waiting time may be a waiting time value, or may be a time when the tracking area update request message is sent.

The implementation manners of the tracking area update method provided by the foregoing embodiments are described in the following specific implementation scenarios.

scene one

25 is a schematic diagram of a cell deployment along a high-speed railway. Referring to FIG. 25, there are five cells, wherein a Tracking Area Code (TAC) of the cell 1 and the cell 2 is a tracking area of the TAC1, the cell 4, and the cell 5. The code is TAC2. In this solution, the cell 3 is used as a buffer, and the cell 3 has both TAC1 and TAC2. Thus, when the UE moves to the cell 3 at a high speed, according to the obtained TAC1 and TAC2, the UE can determine that the tracking area needs to be updated. The process triggers the tracking area update method provided by the above embodiment.

Scene two

When a cell is not enough as a buffer, a plurality of consecutive cells may be used as a buffer, that is, the cells contain two TACs. When the UE moves to the buffer at a high speed, according to the obtained TAC1 and TAC2, the UE may Determine the need to track the zone update process. However, the difference from scenario one is that when the UE performs reselection between two cells in the buffer, the UE reselects to the next cell in the buffer, and the UE in the first cell of the buffer determines to adopt The above mechanism performs backoff. When the UE moves to the second cell, the backoff is not required to be performed, but the previous backoff is still performed, and the TAU process is executed.

Scene three

In addition to broadcasting the first information through the cell of the buffer, another feasible way is to configure through a core network device (for example, an MME), that is, the UE is configured by the core network device during the attaching process. UE. For this case, refer to the description of the second method of step 100 above. Optionally, the first information may also be solidified in the UE. For this case, refer to the description of the third method of step 100 above.

Scene four

The tracking area update method provided by the embodiment of the present invention may also be applied in the case where the buffer is not set. Specifically, no cell broadcasts two TACs, that is, the UE acquires the first information only through an attach procedure or a cell broadcast message or a solidification manner. Specifically, when the UE needs When the TAU is executed, the UE acquires the waiting time according to the first information, and after the waiting time, initiates the TAU process. Further, the condition that the UE determines that the TAU needs to be performed is: when the UE finds that the TAC changes when the cell is reselected, it is determined that the TAU needs to be performed. For example, when the tracking area code obtained by the UE from the previous cell is TAC1, when the mobile station moves to the next cell, the obtained tracking area code is TAC2, and since the two tracking area codes are different, and TAC2 does not belong to the TAI list, The UE determines that a TAU needs to be performed.

Further, for the above scenario 1 and scenario 2, the following describes the specific embodiments.

FIG. 26 is a schematic flowchart of another method for updating a tracking area according to an embodiment of the present invention. The method corresponds to scenario 1, and referring to FIG. 26, based on the method 1 of step 100, step 100 is performed. A feasible implementation is:

Obviously, according to the corresponding embodiment of FIG. 26 and FIG. 27, no matter how the first information is obtained, it is necessary to acquire the TAC later to determine whether the tracking area update process is required.

It should be noted that the step 100c is not limited to be performed after the step 100b, and may be performed at the same time, or the step 100c may be performed before the step 100b, and the step 100c may not exist separately after the step 100b.

Referring to FIG. 27, after step 100c, step 101a is continued.

Further, for the foregoing embodiment corresponding to FIG. 26 and FIG. 27, before the step 101a, the Radio Resource Control (RRC) layer of the UE acquires the first information, the first TAC, and Transmitting, by the second TAC, the first information, the first TAC, and the second TAC to a non-access stratum (NAS) layer of the UE; or The radio resource control RRC layer of the UE acquires the first TAC and the second TAC, and forwards the first TAC and the second TAC to the NAS layer of the UE.

It should be noted that, if the first information is sent to the UE by using the foregoing broadcast message/multicast message/group message, the RRC layer of the UE is obtained from the broadcast message/multicast message/group message; if the first information is Presetting in a storage medium of the UE, the RRC layer of the UE acquires first information from a storage medium of the UE;

Further, after the radio resource control RRC layer of the UE forwards the parameter to the NAS layer of the UE, a feasible implementation manner of the foregoing step 101a is:

Optionally, determining, at the NAS layer of the UE, that the first TAC or the second TAC After the first tracking area identifier list is not included in the method, the NAS layer of the UE determines, according to the first information, the waiting time for sending the tracking area update request message;

Then a feasible implementation of step 102 is:

Specifically, the UE sends a tracking area update request message to the core network device, and a feasible implementation manner is: the lower layer (for example, the RRC layer) of the UE establishes an RRC connection, after the RRC connection is established. The UE sends a tracking area update request message to the core network device.

Another possible implementation manner is that the NAS layer of the UE sends a connection establishment request to the RRC layer of the UE, and the RRC layer of the UE determines to send the tracking area update request message according to the first information. The waiting time;

The first tracking area identifier list is a current tracking area identifier list or a tracking area identifier list that is previously registered by the UE from the core network device or a tracking obtained by the UE before determining whether a tracking area update process needs to be performed. The area identifier list, the first tracking area identifier list includes a tracking area identifier corresponding to the UE in the current tracking area, and the second tracking area identifier list is a tracking area obtained before the UE obtains the first tracking area identifier list. The list of identifiers or the list of previous tracking area identifiers. For step 101b, in the buffer, the UE starts only one waiting time or timer, and the time or timer is valid in the entire buffer, the UE only Perform a tracking area update.

Specifically, the buffer is: when the UE reselects to the cell, and the TAC information still obtained from the cell is consistent with the previous cell, that is, the TAC information is TAC1 and TAC2, then the current cell is compared with the previous cell. The cells are all in the same buffer.

It should be noted that step 100 in FIG. 28 can also be replaced with any feasible implementation manner of step 100 above; similarly, step 102 in FIG. 28 can also be replaced with any feasible implementation manner of step 102 above.
