Description

The present invention relates to the field of communications, and in particular to an access processing method and apparatus. In a mobile communication system, a base station periodically sends system information (also called a system broadcast message), which includes configuration information of a cell, such as a cell identifier, a system bandwidth, a resource configuration, and the like. System information is information that the terminal must access to the cell and must be known to reside in the cell. 1 is a schematic diagram of a repetition period and a modification period of system message transmission in a mobile communication system according to the related art. As shown in FIG. 1, system information is repeatedly transmitted in a fixed repetition period; in some systems, a system is also defined. The modification period of the information, that is, if the system information content is to be changed, it needs to be changed in the next modification cycle. However, some system information changes are not subject to the modification period, such as the system information related to the urgent earthquake tsunami. If the information is to be changed, it can be updated when the next repetition period comes, regardless of whether it is in a new one. At the beginning of the modification cycle, this design can provide the speed at which such information is updated. The modification period is an integer multiple of the repetition period. During the operation of the system, if some content in the system information needs to be updated, since many terminals already reside in the cell at this time, it is first necessary to notify all terminal system that the information is to be changed, and the paging mode (UMTS system) It also includes the means of dedicated signaling. It informs the user that the system information will be changed, and then the system will send the updated system information at the next system modification cycle. When the terminal receives the paging information and knows that the system information is about to be changed, it will re-receive the system information at the next system information modification period. For special system information (that is, a type of information whose modification is not limited by the modification period), if the content of such information needs to be updated, the system first needs to notify all terminals that such special system information will be changed, and can be paged. (The UMTS system also includes a dedicated signaling method) to notify the user, and then the system will send the updated such system information at the next system information repetition period. When the terminal receives the paging information and learns that the special system information is about to be changed, it will start receiving such system information in the next system information repetition period. A user equipment (User Equipment, also referred to as a UE, also referred to as a terminal) needs to perform access control when accessing the network, and is used to determine whether a service request can be initiated to avoid causing network-side overload such as random access overload or signaling. Overload, access information used for access control is included in the system information. If the system determines that the current access information does not meet the system status for some reason, the access information needs to be updated. The terminal is just in progress. The access process or the access process is about to be performed. Because the system information update has a process, if the terminal still accesses the old access information, it may conflict with the newly configured access information of the system, causing the access failure. . 2 is a flowchart of a terminal accessing a base station according to the related art. As shown in FIG. 2, the method includes the following step S202 value step S220. Step S202: The base station periodically sends a system broadcast message. Step S204: The system is congested, and the system broadcast message is triggered to be updated. Step S206: The terminal uses the old access parameter for access. Step S208: The base station sends a Paging notification system message change. Step S210: The terminal acquisition system message is about to be changed. Step S212: After the last access failure of the terminal, the terminal uses the old access parameter for access. Step S214: After the terminal fails to access again, the old access parameter is used again for access. Step S216: The base station periodically sends an updated system broadcast message. Step S218: The terminal receives a new system message. Step S220: The terminal accesses using the new access parameter, and successfully accesses the base station. As shown in the following figure, the first three access attempts made by the terminal are all accessed, and only the last access is finally successful. From the whole process, the first three accesses are not only unsuccessful, but also collide with other users to collide, causing additional interference and wasting the power of the terminal. In summary, in the related art, the random access method of the terminal has a higher number of user access times and a lower probability. SUMMARY OF THE INVENTION The present invention provides an access processing method and apparatus, so as to solve at least the problem that the number of user accesses of the random access method of the terminal in the related art is relatively high and the probability is relatively low.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The embodiment provides an access processing method, and FIG. 3 is a flowchart of an access processing method according to an embodiment of the present invention. The method includes the following steps S302 to S306. Step S302: The terminal receives a message for indicating that the system access information is changed. Step S304: The terminal cancels the currently performed random access processing operation. Step S306: The terminal performs access processing by using the received updated system access information. After the terminal receives the message indicating that the system access information is changed, the terminal cancels the currently performed random access processing, and uses the updated system access information to perform access processing, thereby avoiding access in the system. After the information is changed, the terminal still uses the unaltered system access information for random access, resulting in a low access probability, thereby reducing the probability of random access of the terminal and improving the random connection of the terminal. The probability of entering, at the same time, can reduce the amount of power used by the terminal for accessing because the number of times the terminal performs random access operations is reduced. As a preferred implementation, step S304 can perform different manners according to the state in which the terminal is located: Mode 1: The terminal determines that the terminal is in a state ready to initiate random access and does not perform the operation of the random access, and the terminal stops. The operation of the random access is performed. Manner 2: The terminal determines that the terminal is in a state of attempting random access and does not establish a Radio Resource Control (RRC) connection, and the terminal suspends the operation of the random access being attempted. For the first mode, the terminal is in the state of preparing for random access, but has not performed the random access operation, the terminal may stop the random access operation to be performed; for the second mode, the terminal is attempting to perform random access and is not successfully established. The RRC connection can immediately terminate the operation of performing random access, and the random access can be suspended at this step regardless of which step the current random access operation is performed. That is, any step before establishing an RRC connection with the base station can be used as a dead center for random access. The above two methods can prevent the terminal from using the unupdated system access parameters for access, which may cause collisions and additional interference problems when competing with other users, thereby improving the accuracy of random access of the terminal. And saves the power of the terminal. In implementation, in step S306, the terminal may receive a message that the system access information is changed in multiple manners, as long as the terminal can obtain any message that the system access information is changed, for example: broadcast, dedicated signaling The way to indicate or page. By means of paging, the existing signaling can be used to reduce the signaling load. Preferably, the predetermined field in the paging message in the paging mode may be set to identify one of the following: the system access message is to be sent, the content in the system access message needs to be changed, and the system access message is to be cancelled. Wherein, the system access message to be sent means that the system message is not sent before, the system determines to configure the system message; the content in the system message needs to be changed, that is, the system message is being sent but the content needs to be updated; the system access message To cancel is that the system access message is being sent, but the system decides that it does not need to send again. By identifying different types of system access messages by using a predetermined field of the paging message, the terminal can quickly extract useful information after receiving, and improve the efficiency of random access of the terminal. As a preferred implementation manner, the updated system access information is transmitted in one of the following manners: based on a modification period or based on a repetition period. The base station can transmit in one of the above two ways as needed. For example: For urgently changed system access messages, they can be transmitted at the beginning of the next cycle; to reduce the signaling load, you can choose to transmit at the beginning of the next cycle. As another preferred implementation manner, the system access information includes: an Access Access Barring (EAB) parameter. It should be noted that the steps shown in the flowchart of the accompanying drawings may be performed in a computer system such as a set of computer executable instructions, and, although the logical order is shown in the flowchart, in some cases, The steps shown or described may be performed in an order different than that herein.

The following description will be made in conjunction with the preferred embodiments, and the following preferred embodiments incorporate the above-described embodiments and preferred embodiments. Preferred Embodiment 1 This embodiment provides a method for a terminal to access a system. In this embodiment, when receiving a system information update indication (paging or other manner), the system information is notified (especially system access information, such as When the EAB parameter is to be modified, the UE preparing to initiate random access but not performing the random access procedure will suspend the random access procedure, or the UE that is performing the random access procedure but the random access procedure has not succeeded will suspend the random connection. In the process of entering, after receiving the updated system information (especially system access information, such as EAB parameters), the random access process is performed according to the updated system information. Corresponding to the different states of the terminal, the following two modes can be used: Mode 1: When the terminal is preparing to initiate random access, it receives a system information update indication, and the terminal suspends the random access process, according to the pre- The system information transmission mode is set to receive the updated system information, and then the random access process is performed according to the updated system information parameter. Preferably, the system information mainly refers to system access information, such as EAB parameters. As a preferred implementation manner, the system information update indication in this embodiment may indicate that specific system information is to be sent by setting a specific identifier in the paging (the specific system information is not sent before, and the system determines to configure the specific System information), or will be updated (the specific system information is being sent but the content needs to be updated), or will be canceled (the specific system information is being sent, but the system decides that it does not need to be sent). Preferably, the specific system information has two transmission forms, type 1 modification (including new configuration, update, and cancellation) based on the modification period, type 2 modification (including new configuration, update, and cancellation) based on the repetition period; For a specific system information, one of the two types needs to be agreed in advance, so that after receiving the update indication of the system information, the terminal can read at the correct time according to the transmission form of the system information. Manner 2: When the terminal performs a random access procedure but receives a system information update indication when the random access procedure has not succeeded, the terminal stops performing the random access procedure, and receives the updated according to the preset system information transmission manner. System information, and then re-execute the random access process according to the updated system information parameters. Preferably, the random access attempt has not been successful means that the RRC connection has not been successfully established yet. Preferably, the terminal stops performing the random access procedure, that is, the terminal stops performing the random access procedure, regardless of which step the current random access procedure is performed; any step before the successful establishment of the RRC connection with the system can be used as the suspension point. Preferably, the system information mainly refers to system access information, such as EAB parameters. As a preferred implementation manner, the system information update indication in this embodiment may indicate the user by setting a specific identifier in the paging, indicating that specific system information is to be sent (the specific system information is not sent before, and the system determines Configure this particular system information), or it will be updated (the specific system information is being sent but the content needs to be updated), or will be canceled (the specific system information is being sent, but the system decides that it does not need to be sent again). Preferably, the specific system information has two transmission forms, type 1 modification (including new configuration, update, and cancellation) based on the modification period, type 2 modification (including new configuration, update, and cancellation) based on the repetition period; For a specific system information, one of the two types needs to be agreed in advance, so that after receiving the update indication of the system information, the terminal can read at the correct time according to the transmission form of the system information. Preferably, the re-execution of the random access procedure may be performed by the terminal from the first step of the random access procedure according to the updated system information parameter; or the terminal may be suspended from the previous system according to the updated system information parameter. The point starts to continue to perform the random access process. The second embodiment of the present invention provides a method for the terminal to access the system. In this embodiment, the terminal has started the random access process before receiving the system message update indication. This embodiment includes the following steps S2 to S14. Step S2: The terminal 1 normally resides in a cell, the cell periodically transmits system information, and the terminal 1 has received all system information. Step S4: The terminal 1 is ready to initiate an access process, and the reasons for the initiation of the access include, but are not limited to, the service layer initiates a service, initiates a signaling process, and the like. Step S6: The terminal 1 starts to perform a random access procedure according to the access parameters in the current system information. Preferably, the system parameters used in the access procedure include: access control parameters (AC-barringinfo, access level barring information), random access channel parameters, random access code information, power information, random access maximum retry Number of times, random access response window information, number of information retransmissions, etc. Step S8: When the terminal 1 is ready to perform random access, the system detects that the current load is relatively heavy, and needs to modify the access information to restrict access of a part of users, and starts the system information update process in the system. Specifically, the system needs to notify the user that the system information is to be changed; generally, by setting the system information update indication in the paging process, the terminal receives the paging signaling and finds that the system information update indication is true, and knows that the system information is to be changed. In this embodiment, two types of system information need to be distinguished. The modification of type 1 is based on a modification period, and the modification of type 2 is based on a repetition period; the update indication of two types of system information is independent, that is, independent in paging signaling. Type 1 system information update indication and type 2 system information update indication. For example: If the type 1 system information content is updated, the system first sends the paging signaling and sets the type 1 system information update indication therein. When the next system information modification period comes, the system sends the updated type 1 system information. If the type 2 system information content is updated, the system first sends the paging signaling and sets the type 2 system information update indication therein. When the next system information repetition period comes, the system sends the updated type 2 system information. General system information belongs to type 1. For type 2 system information, there are currently system information for ETWS (address tsunami) and CMAS (commercial alarm) purposes; for a large number of M2M type terminals, access control parameters can also be type 2 By updating the mode, the delay of acquiring new access parameters by the terminal can be reduced, and a situation in which a large number of users are swarmed into the system in a short time and the system is paralyzed can be avoided. Specifically, an ΑΒ information modification indication is set in the Paging signaling, and an EAB (extended access barring extended access prohibition control) is an access control method for the M2M type terminal. The update of the EAB information may be modified according to the system information. To update (belonging to system information type 1) or to update according to the system information repetition period (belonging to system information type 2), one of two methods must be agreed, so that the terminal can know in advance how to update the EAB information. In this embodiment, EAB The information adopts the type 2. The terminal 1 is performing the random access procedure. Since the current access parameter is set by the system according to the previous state, it has not met the current system status or a collision, so the random access performed by the terminal 1 is performed. The attempt has not been successful. In this embodiment, the random access attempt is not successful, that is, the terminal does not finally establish an RRC connection, that is, all the suspensions before the terminal successfully establishes an RRC connection with the system belong to the random access attempt failure. In the existing random access procedure, the terminal is allowed to perform multiple random access attempts. Step S10: The terminal 1 also monitors the paging while performing the random access procedure. According to the system information update indication in the paging signaling, the terminal 1 can know that the system is to send the updated system information. Step S12: The terminal 1 decides to suspend the current random access procedure, and performs system information update. After receiving the new system information, the terminal performs the random access procedure according to the new system information content. The specific random access suspension point may include the following cases, but is not limited to the following cases, and is exemplified below. Case 1: If the UE is performing an ACB (Access class barring) decision, and the timer is disabled. Case 2: If the preamble code sent by the UE does not receive the RAR (random access response) replied by the base station, it is intended to resend the preamble. Case 3: If the UE has not sent msg3, the UE suspends the random access procedure and reads the SIB. Get the new EAB parameters. Case 4: If the UE sends msg3, but does not receive the Msg4 feedback from the base station in the receiving window of the Msg4, or the received ID in the Msg4 does not match its own ID. Step S14: The terminal 1 indicates, according to the type indication in the paging signaling, if the type 1 system information update indication is set, the terminal 1 reads the new system information according to the system information modification period, when the next modification period comes, and then The random access procedure is performed according to the content of the new type 1 system information. If the type 2 system information update indication is set, the terminal 1 reads the new type 2 system information when the next repetition period comes according to the system information repetition period, and then performs random access according to the content of the new type 2 system information. process. In this embodiment, the EAB adopts the type 2 mode, and after receiving the paging signaling, the terminal 1 finds that the "EAB information modification indication" is set, and receives the update according to the system information repetition period at the repetition period of the system information of the next EAB. EAB information. After receiving the updated EAB information, the terminal 1 performs a random access procedure according to the parameters in the EAB information, specifically, if the EAB parameter related to itself changes, the terminal 1 according to the new EAB parameter Whether the number decision allows access and performs the subsequent process; if the EAB parameter associated with itself does not change, the terminal 1 may restart the random access procedure or continue to perform the random access procedure from the previously suspended point, such as the previous stop point. The preamble code (preamble) has been sent twice for the terminal but the RAR response has not been received. At this point, the terminal can continue to send the third preamble code. FIG. 6 is a flowchart 1 of an access processing method according to a preferred embodiment of the present invention. As shown in FIG. 6, the method includes the following steps S602 to S616. Step S602: The base station periodically sends a system broadcast message. Step S604: The system is congested, and the system broadcast message is triggered to be updated. Step S606: The terminal uses the old access parameter for access. Step S608: The base station uses the Paging to notify the system message change. Step S610: The terminal learns that the system message is to be updated. Step S612: The base station sends an updated system broadcast message. Step S614: The terminal receives a new system message. Step S616: The terminal uses the new access parameter for access.

Two

The preferred embodiment of the present invention provides a method for a terminal to access a system. In this embodiment, the terminal starts the random access process after receiving the system message update indication. The method in this embodiment includes the following steps S20 to S80: Step S20: The terminal 2 normally resides in a cell, the cell periodically transmits system information, and the terminal 2 has received all system information. Step S40: During the running of the system, the system detects that the current load is relatively heavy, and needs to modify the access information to restrict the access of some users, and start the system information update process in the system. Preferably, the system needs to inform the user that the system information is about to change. Generally, by setting the system information update indication in the paging process, the terminal receives the paging signaling and finds that the system information update indication is true, and knows that the system information is to be changed. In this embodiment, two types of system information are distinguished, the modification of type 1 is based on a modification period, and the modification of type 2 is based on a repetition period; the update indication of two types of system information is independent, that is, there is an independent type 1 in paging signaling. System information update indication and type 2 system information update indication. For example: If the type 1 system information content is updated, the system first sends the paging signaling and sets the type 1 system information update indication therein. When the next system information modification period comes, the system sends the updated type 1 system information. If the type 2 system information content is updated, the system first sends the paging signaling and sets the type 2 system information update indication therein. When the next system information repetition period comes, the system sends the updated type 2 system information. General system information belongs to type 1. For type 2 system information, there are currently ETWS (address tsunami) and CMAS (commercial alarm) uses; access control parameters for a large number of M2M type terminals can also be updated by type 2 The delay of acquiring new access parameters by the terminal can be reduced, and a situation in which a large number of users are swarmed into the system in a short time and the system is paralyzed is avoided. As a preferred implementation manner, a ΑΒ information modification indication is set in the Paging signaling. The EAB (Extended Access Barring Extended Access Control) is an access control method for the M2M type terminal.

The update of the EAB information may be updated according to the system information modification period (belonging to the system information type 1) or according to the system information repetition period (belonging to the system information type 2), but one of two ways is required, so that the terminal can know the EAB in advance. How information is updated. In this embodiment, the EAB information adopts the type 2 manner. Step S60: The terminal 2 periodically monitors the paging, and according to the system information update indication in the paging signaling, the terminal 2 can know that the system is to send the updated system information. Step S80: The terminal 2 indicates, according to the type indication in the paging signaling, if the type 1 system information update indication is set, the terminal 2 reads the new system information according to the system information modification period, when the next modification period comes, and then The random access procedure is performed according to the content of the new type 1 system information. For example: If the type 2 system information update indication is set, the terminal 2 reads the new type 2 system information when the next repetition period comes according to the system information repetition period, and then performs random according to the content of the new type 2 system information. Access process. For example, when the terminal 2 receives the Paging signaling and knows that the system is about to send the updated system information, the terminal 2 is ready to initiate an access procedure, and the reason for the initiated access includes but is not limited to: the service layer initiates a service. , initiate a signaling process, and so on. At this time, the terminal 2 suspends the random access process, and first performs the system information update process, and then starts to perform the random access process according to the new system information content after receiving the new system information. Preferably, the system parameters used in the access procedure include: access control parameters (AC-barringinfo, access level barring information), random access channel parameters, random access code information, power information, random access maximum retry Number of times, random access response window information, number of information retransmissions, etc. In this embodiment, the EAB adopts the type 2 mode, and after receiving the paging signaling, the terminal 2 finds that the "EAB information modification indication" is set, and receives the update according to the system information repetition period after the repetition period of the system information of the next EAB. EAB information. After receiving the updated EAB information, the terminal 2 performs a random access procedure according to the parameters in the EAB information. FIG. 7 is a second flowchart of an access processing method according to a preferred embodiment of the present invention. As shown in FIG. 7, the method includes the following steps S702 to S714. Step S702: The base station periodically sends a system broadcast message. Step S704: The system is congested, and the system broadcast message is triggered to be updated. Step S706: The base station uses the Paging to notify the system message change. Step S708: The terminal learns that the system message is to be updated. Step S710: The base station periodically sends an updated system broadcast message. Step S712: The terminal receives a new system message. Step S714: The terminal accesses by using a new access parameter. With the foregoing embodiment, an access processing method and apparatus are provided. After the random access succeeds or when the random access is to be performed or the system message is to be changed, the terminal performs random access after updating the system information. , can reduce random access attempts due to inconsistent access parameters, can reduce random access Incoming interference into the channel saves power consumption of the terminal.
