Description

Method, device and system for acquiring access control information The present application claims to be filed on September 29, 2011, the Chinese Patent Office, the application number is 201110301421.4, and the invention name is "a method, device and system for acquiring access control information" The priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference. Technical field

The present invention relates to the field of communication networks, and in particular, to a method, device and system for acquiring access control information. Background of the invention

In the current communication network, each terminal determines whether it is allowed to access according to the access control information in the broadcast message before accessing the network. The access control information in the current broadcast message is for all users. When a user comes to the cell, it will actively read the broadcast message of the cell and store the broadcast message in the terminal. When the broadcast message of the cell changes, the base station will page all the users in the cell, and inform the user that the broadcast message has changed by a broadcast information change indication in the paging message. By using the P-RNTI (Paging-radio network temporary identity) as the interception identifier of the physical control channel, when the user listens to the P-RNTI identifier, it acquires the paging message and parses the paging message. The broadcast information change indication in the call message is learned that the user broadcast message changes, and the user will go to obtain a new broadcast message.

EAB (Extended Access Barring) is an type of access control information proposed by users who configure EAB. Only when users who configure EAB enter the cell, they can judge whether they can access according to EAB information. It is not applicable to other users who do not have EAB information.

In the prior art, when the EAB information is transmitted, the broadcast message carries the EAB information, due to the EAB. When the information changes and the broadcast message changes, the P-RNTI is used on the PDCCH (physical downlink control channel) to schedule the paging message, and the broadcast information change indication in the paging message is used to inform the user to acquire a new message. Broadcast information. The user can know whether the EAB information changes through the paging message, and acquires a new broadcast message when the broadcast message changes. In the conventional broadcast message receiving mechanism, the user waits until the next broadcast message change cycle to acquire a new broadcast message, and also changes the broadcast message receiving mechanism so that the user can obtain a new broadcast message in the current cycle.

In the prior art, when the EAB information is transmitted, the EAB information is placed in the paging message. When the EAB information is changed, the user receives the paging message, and the EAB information can be obtained without acquiring the broadcast information to obtain the EAB information.

In the process of implementing the present invention, the inventors have found that at least the following problems exist in the prior art: In the prior art 1, all users in the cell are queried only because the EAB information changes, and the paging message only informs the broadcast message that there is Change, the user does not know whether this change involves EAB information. Users who do not configure EAB also need to read paging messages that are useless to themselves, which is obviously a waste for users who do not configure EAB.

In the prior art 2, the paging message is used to carry the EAB information, and the operation of the user to receive the broadcast message is omitted, but the user who does not configure the EAB still receives the useless paging message; and the paging message has a limited capacity. Limits the capacity of EAB information. Summary of the invention

In order to solve the problem that the EAB information is changed, the user who does not configure the EAB does not receive the RRC (Radio Resource Control) message including the EAB information, and the embodiment of the present invention provides a method and apparatus for acquiring the access control information.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. When the access control information in the broadcast message of the cell changes, the network side notifies the user in the cell through the PDCCH channel, and after the user listens to the identifier of the change of the access control information, the broadcast message is changed, and the user obtains the information. New broadcast message. In the actual application, a set of information is set for the user who is configured. In the embodiment of the present invention, a first identifier is set for the user configuring the UI, and the first identifier is a new identifier, which is similar to the P-RNTI function, and the new identifier is configured for the user of the configuration UI, and can be configured. Users that are monitored by the user and are not configured can not be monitored. That is, only users configured with ΕΑΒ will judge whether they can access the cell according to the ΕΑΒ information, but not for other users who are not configured. Be applicable. When the broadcast message changes due to the change of the ΕΑΒ information, the user who configures ΕΑΒ listens to the new identifier, so that the user configuring the 获 knows that the current broadcast message has changed, and the configured user will obtain a new broadcast message. The present invention is described by taking the first identifier as an X-RNTI identifier as an example. Of course, X has no specific meaning, and is only an identifier, which may also be called EAB-RNTI, a new RNTI identifier, etc., and the present invention does not do this. limited. In the embodiment of the present invention, an H2H user that is not configured with an EAB is referred to as an ordinary user, and an H2H user that is configured with an EAB is referred to as a user who configures an EAB. The EAB information is simply referred to as EAB information for description.

After the H2H user listens to the PDCCH message that is scrambled by the X-RNTI identifier in the PDCCH channel, an operation of decoding the X-RNTI identifier is added, and the decoding of the X-RNTI by the ordinary user fails, and the user who configures the EAB will The decoding was successful. After the user of the EAB is successfully decoded, the RRC message on the Physical Downlink Shared Channel (PDSCH) is received. The RRC message contains the EAB information, so that the EAB information can be changed by the content of the RRC message. In the embodiment of the present invention, the RRC message may be a new message, and an existing message, such as a paging message PAGING message, may also be used. Embodiment 1 Referring to FIG. 1 , an embodiment of the present invention provides a method for acquiring access control information, where the method includes: Step 101: Receive a control message that is sent by a network side and is scrambled by a first identifier, after the first The control message that identifies the scrambling can be monitored by the user configured with the extended access control EAB, and the user who is not configured with the EAB is not available, and the control message includes scheduling information on the physical downlink control channel PDCCH;

Step 102: Perform descrambling on the control message scrambled by the first identifier to obtain a control message, and receive a radio resource control RRC message on the physical downlink shared channel PDSCH according to the scheduling information in the control message, where the RRC message includes EAB related information. Step 103: Obtain EAB information according to EAB related information. The method provided by the embodiment of the present invention, by setting a unique first identifier for the user configuring the EAB, enables the user configuring the EAB information to receive the control message scrambled by the first identifier when the EAB information is changed. To the EAB information, for ordinary H2H users, since the control message is not descrambled using the first identifier, the RRC message will not be received, and the RRC message will not be received. Receiving EAB information, ordinary H2H users will not receive messages that are useless to themselves, reducing the amount of reception by ordinary users.

The following is a detailed description of a specific application scenario: Embodiment 2 In the embodiment of the present invention, the EAB related information is specifically EAB information, and the EAB information is set in the RRC message on the network side. When the EAB information changes, the network side sends the X. - The RNTI identifies the scrambled control message, so that the user configuring the EAB can learn that the EAB information has changed through the X-RNTI identifier. In actual application, the EAB information is used by the user configuring the EAB, and the RRC message can be a new message. It can be an existing message, such as scheduling a PAGING message.

Referring to FIG. 2, an embodiment of the present invention provides a method for obtaining EAB information, where the method includes:

Step 201: Receive an X-RNTI scrambled control message delivered by the network side, where the control message includes scheduling information on the PDSCH channel. The implementation of the embodiment of the present invention is mainly to configure the user of the EAB, only in the scenario that the EAB information of the cell changes. Specifically, the network side sends a control message to the user in the cell through the PDCCH channel, and the control message passes the X- RNTI scrambles. When all the H2H users in the cell listen to the control message and configure the user of the EAB to listen to the X-RNTI, go to step 202. When the normal user listens to the X-RNTI, it knows that the current control message is related to the user who configures the EAB, but has nothing to do with it. , no action is taken. Step 202: De-scramble the control message, parse out the control message, and receive an RRC message according to the scheduling information in the control message, where the RRC message includes EAB information.

Specifically, when the user configuring the EAB listens to the X-RNTI, it learns that the currently changed access control information is related to itself, and after receiving the control message, uses the X-RNTI to descramble the control message. A control message is obtained, and an RRC message is received on the PDSCH channel according to the scheduling information in the control message.

In an actual application, the ordinary user does not receive the RRC message on the PDSCH channel because the control message on the PDCCH channel is not descrambled. Therefore, for the ordinary user, the RRC message that is useless to itself is not received.

Step 203: Parse the RRC message to obtain EAB information. The operation of the EAB user to parse the EAB information in the RRC message is not described herein. After the user configuring the EAB parses the EAB information, it determines whether the cell is allowed to access the cell according to the EAB information. The method provided by the embodiment of the present invention sets a specific first identifier, that is, an X-RNTI identifier, for the user who configures the EAB, and when the EAB information is changed, the configuration message is sent by the first identifier to be configured. The user of the EAB information can receive the EAB information, and for the ordinary H2H user, since the control message is not descrambled by using the first identifier, the RC message is not received, and the EAB information is not received, so the ordinary H2H user It will not receive messages that are useless to itself, reducing the amount of reception by ordinary users.

Embodiment 3 In the embodiment of the present invention, the EAB related information is specifically EAB indication information, and the EAB information is set in the broadcast message on the network side, and the EAB information is indicated by using an RRC message, where the RRC message includes the EAB indication information. After this indication information, it can be judged that there is a new update of the EAB information in the broadcast message, thereby obtaining the EAB information in the broadcast message. In practical applications, the EAB information is used by the user configuring the EAB, and the RRC message may be a new message or an existing message, such as scheduling a PAGING message. Referring to FIG. 3, an embodiment of the present invention provides a method for obtaining ΕΑΒ information, where the method includes:

Step 301: Receive a control message sent by the network side, where the control message includes scheduling information on the PDSCH channel, and is scrambled by the X-RNTI.

The execution subject of the embodiment of the present invention is a user configured with ΕΑΒ, but in a scenario where the ΕΑΒ information of the cell changes, the network side sends a control message to the cell through the PDCCH channel, and the control message is scrambled by the X-RNTI. This step is the same as step 201 in Embodiment 2, and the present invention will not be described again. Step 302: De-scrambling the control message, parsing the control message, and receiving the RRC message according to the scheduling information in the control message, where the RRC message includes the indication information.

When the user configured with the 监听 listens to the X-RNTI, it learns that the currently changed access control information is related to itself. After the configuration, the user uses the X-RNTI descrambling control message to parse the control message, and then receives the RRC message on the PDSCH channel according to the scheduling information in the control message. The RC message may be a new RRC message, or may be an existing PAGING. Message.

Specifically, the RRC message in the embodiment of the present invention includes EAB indication information, which is used to indicate that the EAB information in the broadcast message has a new update, so that the user obtains the EAB information in the broadcast message according to the EAB indication information. Step 303: Parsing the RRC message, obtaining the EAB indication information, and acquiring the broadcast message according to the EAB indication information, where the broadcast message contains the EAB information. Specifically, the EAB indication information is used to notify the user that the broadcast message is changed, and the user configuring the EAB can obtain the new broadcast message according to the EAB indication information, and the new broadcast message includes the EAB information. Step 304: Parse the broadcast message to obtain EAB information. The operation of the EAB user to parse the EAB information in the broadcast information is not described herein. After the EAB user parses the EAB information, it determines whether it is allowed to access the cell according to the EAB information. The method provided by the embodiment of the present invention, by setting a unique first identifier for the user configuring the EAB, enables the user configuring the EAB information to receive the control message scrambled by the first identifier when the EAB information is changed. To the EAB information, for the ordinary H2H user, since the control message is not descrambled by using the first identifier, the RRC message will not be received, and the EAB information will not be received, so the ordinary H2H user will not receive the self. Useless messages, reducing the amount of normal user reception.

Embodiment 4 Referring to FIG. 4, an embodiment of the present invention provides a method for sending access control information, where the method includes: Step 401: Perform scrambling on a control message according to a first identifier, and perform control through scrambling of the first identifier. The message can be monitored by the user who is configured with the extended access control EAB, and the user who is not configured with the EAB does not have any information. The control message includes the scheduling information on the physical downlink control channel PDCCH. Step 402: The first identifier is sent. The disturbed control message enables the user configuring the EAB to receive the RRC message according to the scheduling information in the control message, and obtain the EAB information. The method provided by the embodiment of the present invention, by setting a unique first identifier for the user configuring the EAB, enables the user configuring the EAB information to receive the control message scrambled by the first identifier when the EAB information is changed. To the EAB information, for the ordinary H2H user, since the control message is not descrambled by using the first identifier, the RRC message will not be received, and the EAB information will not be received, so the ordinary H2H user will not receive the self. Useless messages, reducing the amount of normal user reception. Embodiment 5 In the foregoing embodiment, by providing a dedicated X-RNTI for the user configuring the EAB, the PDCCH channel control message is descrambled, and the PDSCH message is obtained, and finally the desired EAB information is obtained. However, for the user in the IDLE idle state, if the user uses the discontinuous reception model, the user only listens to the PDCCH channel when waking up, to obtain the X-RNTL it wants in the current mechanism. The user only listens to the P-RNTI when the user wakes up. The embodiment of the present invention mainly clarifies the wake-up time of the X-RNTI. The following is a detailed description of whether the P-RNTI and the X-RNTI use the same listening period, where the P-RNTI and the X-RNTI use the same listening period, indicating that the user configuring the EAB listens to the X-RNTI or The time of the P-RNTI is the same as the time when the normal user listens to the P-RNTI.

In the embodiment of the present invention, when the P-RNTI and the X-RNTI use the same listening period, the wake-up time of the X-RNTI is clarified. When the P-RNTI and the X-RNTI use the same listening period, the user configuring the EAB may listen to the P-RNTI and may also listen to the X-RNTI when waking up. The network side performs a corresponding notification mechanism to implement the scenario in which the P-RNTI and the X-RNTI are used together according to whether the public broadcast information and the EAB information of the current user are changed. Step 501: Determine whether the public broadcast information changes. If the change occurs, perform the steps.

502. Otherwise, step 505 is performed. The execution of this embodiment is mainly on the network side. Specifically, when the public broadcast information does not change, only when the EAB information changes, the network side uses the X-RNTI identifier set by the user configured with the EAB to notify the user who configures the EAB; when the public broadcast information changes, Then, different notification mechanisms are executed according to whether the EAB information changes.

Step 502: Determine whether the current EAB information changes. If the change occurs, perform the step.

503, otherwise step 504 is performed; The network side determines whether the EAB information changes or not, and determines whether the public access control information changes. The public broadcast information refers to broadcast information that is common to all users. In the embodiment of the present invention, the network side performs different notification mechanisms according to three different application scenarios. The three application scenarios in the embodiment of the present invention are as follows: The EAB information does not change, and the public broadcast information of all users changes; the EAB information changes, and the public broadcast information of all users does not change; EAB information and all The public broadcast information of the user changes. Step 503: The paging message is scheduled by using the P-RNTI, and the public broadcast information and the indication information that the EAB information is changed are set in the paging message. Specifically, the application scenario of the step is that the EAB information and the broadcast information common to all users are changed, and the public broadcast information and the EAB information are changed, and the user is used to schedule all users to obtain the public broadcast information and configure the EAB. Get specific EAB information. Step 504: Scheduling an RRC message by using a P-RNTI, where the RRC message includes indication information of a broadcast message change. The RRC message may be a new message or a PAGING message in the PSCCH channel, and the new message or the PAGING message includes indication information of the broadcast message change. Specifically, the application scenario of the step is that the EAB information does not change, and the broadcast information of all users changes. In this application scenario, the notification mechanism on the network side is the same as the existing notification mechanism. Step 505: Scheduling an RRC message by using an X-RNTI, where the RRC message may include specific EAB information or indication information that the EAB information changes. Specifically, the application scenario of the step is that the broadcast information common to all users does not change, and only the EAB information changes. For details, refer to the foregoing embodiment. Wherein, the user who configures the EAB The EAB information may be directly obtained, or the specific EAB information may be further obtained according to the indication information that the EAB information changes. The method provided by the embodiment of the present invention adopts a different notification mechanism when different monitoring access information changes when the monitoring period of the common identifier and the first identifier is the same, when only the EAB information changes, H2H users will not receive EAB information, which reduces the amount of reception by ordinary users.

Embodiment 6 For a user in the IDLE idle state, if the user adopts a discontinuous reception model, the user only listens to the PDCCH channel when waking up, to obtain the X-RNTL it wants in the current mechanism. The user only listens to the P-RNTI at the moment of waking up. The embodiment of the present invention mainly clarifies the wake-up time of the X-RNTI. In the embodiment of the present invention, when the P-RNTI and the X-RNTI adopt different listening periods, the wake-up time of the X-RNTI is clarified. The user configuring the EAB acquires the control message on the PDCCH channel by using the X-RNTI, and then receives the EAB information on the PDSCH channel. When the EAB information of the cell changes, the network side only informs the user who configures the EAB through the X-RNTI, and the user who does not configure the EAB will not be affected.

Step 601: Set a first listening period for all users, and set a second listening period for the user configuring the EAB;

The execution of this embodiment is mainly on the network side. Specifically, all users include a normal user and a user who configures the EAB. All users determine their first wake-up time according to the first listening period, and listen to the P-RNTI at the first wake-up time. The second listening period determines its own second wake-up time and listens to the X-RNTI at the second wake-up time. The first listening period can be set to the default paging cycle, and the second listening period can be set to the default cycle. Step 602: The first RRC message on the PDSCH is scheduled by sending a P-RNTI in the first listening period, where the first RRC message includes indication information of a broadcast message change, and is scheduled by sending an X-RNTI in a second listening period. A second RRC message on the PDSCH, where the second RRC message includes indication information that the EAB information or the EAB information changes. The first RRC message or the second RRC message may be a new message or a paging message in the PDSCH channel.

In an actual application, an ordinary user in the network monitors the P-RNTI according to the first waking time; the user configuring the EAB listens to the P-RNTI according to the first waking time, and monitors according to the second waking time.

Specifically, by setting different listening periods, for users in the IDLE idle state, when the user configuring the EAB wakes up, it can be known whether the current monitoring is P-RNTI or X-RNTI. In the method provided by the embodiment of the present invention, when the monitoring period of the first identifier X-RNTI and the public identifier P-RNTI is different, the listening period is set, so that the user in the cell wakes up to know his own monitoring information, and only the EAB is available. When the information changes, the ordinary H2H user will not receive the EAB information, which reduces the receiving amount of the ordinary user.
