Description

Terminal state control method, message transmission method, device and equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method, a device, and an apparatus for controlling a terminal state.

Background

Currently multicast traffic is only supported on the air interface for reception in the radio resource control (Radio Resource Control, RRC) connected state. When the multicast service state of the core network changes, for example, the multicast service is changed from an active state to a deactivated state, the base station can release the terminal to an idle state or a non-active state so as to achieve the energy saving effect. Or the core network multicast service is still in an active state, but the base station can release the terminal to an inactive state because of no data transmission temporarily. When the multicast service of the core network is changed from the inactive state to the active state, or the data arrives again, the base station needs to change the idle state or inactive state terminal to the connection state so as to continuously receive the multicast service.

The base station controls the terminal to perform state conversion through the paging message, and for a certain multicast service, the base station includes a multicast service identifier in the paging message, then sends the paging message on the paging occasion (Paging Occasion, PO) of the corresponding terminal, and after receiving the paging message, the terminal judges whether to enter a connection state according to the multicast service identifier.

Detailed Description

In the embodiment of the application, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The subsequent enhancement of the multicast service considers the congestion and other scenes, and in order to allow more terminals to access the service, the multicast service can be supported to be received in an RRC idle state or a non-activated state, namely, for a certain multicast service, the RRC connection state terminal and the non-connection state terminal can receive at the same time. Since congestion may be temporary, when network congestion is relieved, the network may need to transfer the terminal in an idle state or inactive state to a connected state to continue to receive multicast services, so as to obtain better service experience. The existing paging mode is aimed at the multicast service level, that is, the base station controls all terminals interested in the service to enter a connection state to continuously receive the multicast service by including the multicast service identifier in the paging message. It can be seen that the existing mechanism cannot solve the problem that after network congestion is relieved, part of terminals are converted into a connection state to continue receiving multicast services.

In order to solve the above problems, embodiments of the present application provide a terminal state control method, a message transmission method, a device, and equipment. The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

As shown in fig. 1, a flow chart of a terminal state control method provided by an embodiment of the present application is applied to a terminal, and includes:

step 101: and receiving paging information sent by network side equipment, wherein the paging information comprises a multicast service identifier and/or a first information field, and the first information field is used for indicating a packet identifier of a packet where a terminal joining the multicast service corresponding to the multicast service identifier is located.

Optionally, the first information field comprises a list of packet identifications. After the network side device performs grouping for the terminal joining the multicast service, the grouping identifier for identifying the grouping where the terminal is located can be represented by a grouping identifier list. It should be noted that, the specific content of the first information field is determined by the network side device, that is, the network side device wants which terminal in the packet to perform the state transition (from the non-connected state (such as the idle state or the inactive state) to the connected state), and then the packet identifier of which packet is included in the first information field.

Here, the multicast service identifier (Temporary Mobile Group Identity, TMGI) is used to enable the terminal to determine, through the multicast service identifier, whether the multicast service corresponding to the multicast service identifier is a multicast service that the terminal is interested in monitoring.

Step 102: and controlling the terminal according to the paging message, wherein the control comprises whether the idle state or the inactive state is converted into the connection state.

When the paging message sent by the network side equipment comprises the first information field for indicating the packet identifier of the packet where the terminal joining the multicast service corresponding to the multicast service identifier is located, the control of the network side equipment can realize that part of idle state or non-active state terminals enter a connection state to continuously receive the multicast service, so that service experience is better improved.

In order to accurately implement the transition control on the terminal status, in an alternative embodiment, the step 102 may include:

Step 1021, judging whether to switch from an idle state or an inactive state to a connection state according to the paging message and a first indication, wherein the first indication is a multicast service state indication or a multicast configuration update indication;

here, the multicast service state specifically refers to a state of a multicast service corresponding to the multicast service identifier in the paging message.

Step 1022: if the judgment result is yes, converting the terminal state from an idle state or an inactive state into a connection state;

step 1023: if the judgment result is negative, the terminal state is maintained in the current state, and the current state is an idle state or an inactive state.

In an alternative embodiment, the step 1021 may include

Here, the multicast service corresponding to the multicast service identifier is the multicast service of interest to the terminal, the indicated multicast service state is the active state, and the determination and judgment result is that the terminal can be converted from the current state (idle state or inactive state) to the connection state, and the multicast service is continuously received on the connection state, so that the service experience is better improved.

And/or the terminal matches the packet identifier in the first information domain, the terminal determines that the paging message sent by the network side device is directed at the terminal, the indicated multicast service state is an active state, the terminal can convert the current state (idle state or inactive state) into a connection state if the determination result is yes, and the terminal continues to receive the multicast service on the connection state, so that service experience is better improved.

If the multicast service corresponding to the multicast service identifier is one or more of the multicast service which is not interested by the terminal, the packet identifier which is not matched by the terminal, and the indicated multicast service state is in an inactive state, the judgment result is no.

It should be noted that, because the network side device wants to update the multicast configuration, when the network side device wants to transfer all the idle state or inactive state terminals to the connection state to receive the multicast service, the network side device issues a multicast configuration update indication, and when the terminal obtains the multicast configuration update indication and the multicast service corresponding to the multicast service identifier is the multicast service of interest to the terminal, the terminal will change the current state (idle state or inactive state) to the connection state, and continue to receive the multicast service on the connection state, so as to better promote service experience.

If any of the above conditions is not satisfied, the determination result is no. That is, if the multicast service corresponding to the multicast service identifier is a multicast service that is not interested by the terminal and/or the first indication is not a multicast configuration update indication, determining that the judgment result is no.

In an optional embodiment, the paging message further includes the multicast service status indication, and the method of the embodiment of the present application may further include:

When the terminal obtains the multicast service state indication, if the multicast service state indication is activated, the terminal judges that the multicast service is activated, that is, the multicast service state is an activated state; if the multicast service state indicates deactivation, judging that the multicast service is not activated, namely, the multicast service state is the deactivation state.

Optionally, the paging message further includes the multicast configuration update indication.

In an alternative implementation, before the step 101, the method according to the embodiment of the present application may further include:

I.e. the RRC reconfiguration message includes the packet identity of the packet in which the terminal is located.

I.e. the RRC release message includes the packet identity of the packet in which the terminal is located.

The terminal state control method of the embodiment of the application receives the paging message sent by the network side equipment, wherein the paging message comprises a multicast service identifier and/or a first information field, and the first information field is used for indicating the packet identifier of the packet where the terminal joining the multicast service corresponding to the multicast service identifier is located; and controlling the state of the terminal according to the paging message, wherein the control comprises whether the idle state or the inactive state is converted into the connection state, so that the control of the network side equipment can realize that part of the idle state or the inactive state terminal enters the connection state to continuously receive the multicast service, and the service experience is better improved.

As shown in fig. 2, a flow chart of a message transmission method provided by an embodiment of the present application is applied to a network side device, and includes:

Step 201: and sending a paging message to the terminal, wherein the paging message comprises a multicast service identifier and/or a first information field, the first information field is used for indicating a packet identifier of a packet where the terminal joining the multicast service corresponding to the multicast service identifier is located, the paging message is used for indicating the terminal to control the state of the terminal according to the paging message, and the control comprises whether the state is converted from an idle state or an inactive state to a connection state.

Optionally, the first information field comprises a list of packet identifications. After the network side device performs grouping for the terminal joining the multicast service, the grouping identifier for identifying the grouping where the terminal is located can be represented by a grouping identifier list.

It should be noted that, the specific content of the first information field is determined by the network side device, that is, the network side device wants which terminal in the packet to perform the state transition (from the non-connected state (such as the idle state or the inactive state) to the connected state), and then the packet identifier of which packet is included in the first information field.

Here, the multicast service identifier is used for enabling the terminal to determine whether the multicast service corresponding to the multicast service identifier is the multicast service interested in monitoring by the terminal through the multicast service identifier.

According to the message transmission method, the paging message is sent to the terminal, the paging message comprises the multicast service identifier and/or the first information field, the first information field is used for indicating the packet identifier of the packet where the terminal joining the multicast service corresponding to the multicast service identifier is located, the paging message is used for indicating the terminal to control the state of the terminal according to the paging message, and the control comprises whether the state is converted from the idle state or the inactive state to the connection state, so that the terminal in the idle state or the inactive state enters the connection state to continuously receive the multicast service through the control of the network side equipment, and the service experience is better improved.

Optionally, the method of the embodiment of the present application may further include:

Optionally, the paging message further includes a multicast service status indication or a multicast configuration update indication.

The following describes a process of realizing terminal state transition control by mutually cooperating network side equipment and a terminal through a specific embodiment.

Example 1

1. The terminal 1, the terminal 2, the terminal 3, the terminal 4 and the terminal 5 are currently in an RRC connection state and are receiving a certain multicast service TMGI, and the base station sends the packet identification aiming at the terminal joining the multicast service to the terminal through an RRC reconfiguration message.

For example, the base station decides to divide the terminals in a connection state that are receiving the multicast service into three groups, and associates the terminals with index1, index2 and index3 respectively, for example, terminal 1 and terminal 2 are associated with index1, terminal 3 is associated with index2, and terminal 4 and terminal 5 are associated with index3, and then the base station sends the corresponding packet identifier to the terminal through an RRC reconfiguration message.

2. For reasons of network congestion, the base station decides to release part of the terminals to the idle state or inactive state to receive the multicast service, e.g. the base station sends RRC release messages to terminal 1, terminal 2, terminal 3 and terminal 4, releasing them to the idle state or inactive state.

3. For congestion relief and other reasons, the base station wants to transfer part of the terminals to a connection state to receive the multicast service, for example, the base station judges that the multicast service identifier TMGI and the packet identifier index1 are included in the paging message after the resource relief condition is judged.

4.1, After detecting the paging message, the terminal 1 and the terminal 2 initiate RRC state transition to enter the connected state to receive the multicast service if the paging message contains the multicast service identifier TMGI interested in monitoring and the packet identifier index1 acquired in the connected state and judges that the current multicast service state is the activated state

After detecting the paging message, the terminal 1, the terminal 2, the terminal 3 and the terminal 4 find that the paging message contains the multicast service identifier TMGI interested in monitoring, and meanwhile the paging message also contains the first information field of the packet identifier list, but the content of the first information field is empty, and the terminal judges that the current multicast service state is an active state, so that the terminal 1, the terminal 2, the terminal 3 and the terminal 4 remain in the current state to continuously receive the multicast service.

Example 2

1. Terminal 1, terminal 2, terminal 3, terminal 4 and terminal 5 are currently in RRC connected state receiving a certain multicast service TMGI.

Due to network congestion and the like, the base station decides to release the terminal 1, the terminal 2, the terminal 3 and the terminal 4 to an idle state or an inactive state to continue receiving the multicast service. The base station sends RRC release messages to the terminal 1, the terminal 2, the terminal 3 and the terminal 4, and the RRC release messages contain packet identifications corresponding to the terminals.

For example, terminal 1 and terminal 2 are associated with index1, and terminal 3 and terminal 4 are associated with index2

2. For congestion relief and other reasons, the base station wants to transfer part of the terminals to a connection state to receive the multicast service, for example, the base station judges that the multicast service identifier TMGI and the packet identifier index1 are included in the paging message after the resource relief condition is judged.

3.1, After detecting the paging message, the terminal 1 and the terminal 2 initiate RRC state transition to enter a connection state to receive the multicast service if the paging message contains the multicast service identifier TMGI interested in monitoring and the packet identifier index1 acquired in the RRC release message and judges that the current multicast service state is an active state.

3.2, After the paging message is detected by the terminal 1, the terminal 2, the terminal 3 and the terminal 4, if the paging message is found to contain the multicast service identifier TMGI interested in monitoring, and meanwhile the paging message also contains the first information field of the packet identifier list, but the content of the first information field is empty, and the terminal judges that the current multicast service state is an activated state, the terminal 1, the terminal 2, the terminal 3 and the terminal 4 are left in the current state to continuously receive the multicast service.

Example 3

2. For reasons such as multicast service deactivation, the base station decides to release part or all of the terminals to an idle state or an inactive state, e.g. the base station sends RRC release messages to terminal 1, terminal 2, terminal 3 and terminal 4, releasing them to the idle state or inactive state.

3. Because the multicast service is activated, the base station wants to transfer part of the terminals to a connection state to receive the multicast service, for example, the base station includes the multicast service identifier TMGI and the packet identifier index1 in the paging message after judging the available resource condition.

And 4.1, after the terminal 1 and the terminal 2 detect the paging message, if the paging message is found to contain a multicast service identifier TMGI which is interested in monitoring and a packet identifier index1 which is acquired in a connection state. Additionally, the paging message further includes a multicast service state activation instruction, and then it is determined that the current multicast service is activated, and the terminal 1 and the terminal 2 initiate RRC state transition to enter a connected state to receive the multicast service.

4.2, Terminal 1, terminal 2, terminal 3 and terminal 4 detect paging message, if find paging message include interested multicast service identification TMGI that monitor, also include the first information field of the grouping identification list in paging message at the same time, but the content of the first information field is empty. Additionally, the paging message further includes a multicast service status activation instruction, and then it is determined that the current multicast service is activated, and the terminal 1, the terminal 2, the terminal 3 and the terminal 4 remain in the current status to continue receiving the multicast service.

Example 4

The base station decides to release the terminals 1, 2, 3 and 4 to the idle state or inactive state due to the multicast service deactivation, etc. The base station sends RRC release messages to the terminal 1, the terminal 2, the terminal 3 and the terminal 4, and the RRC release messages contain packet identifications corresponding to the terminals.

2. For reasons such as multicast service activation, the base station wants to transfer part of the terminals to a connection state to receive the multicast service, for example, the base station includes the multicast service identifier TMGI and the packet identifier index1 in the paging message after judging the available resource condition.

3.1, After detecting the paging message, the terminal 1 and the terminal 2 determine that the current multicast service is activated if the paging message contains the multicast service identifier TMGI interested in monitoring and the packet identifier index1 obtained in the RRC release message, and additionally the paging message also contains a multicast service state activation instruction, and the terminal 1 and the terminal 2 initiate RRC state transition to enter a connection state to receive the multicast service.

3.2, Terminal 1, terminal 2, terminal 3 and terminal 4 detect paging message, if find paging message include interested multicast service identification TMGI that monitor, also include the first information field of the grouping identification list in paging message at the same time, but the first information field content is empty. Additionally, the paging message further includes a multicast service status activation instruction, and then it is determined that the current multicast service is activated, and the terminal 1, the terminal 2, the terminal 3 and the terminal 4 remain in the current status to continue receiving the multicast service.

Example 5

3. For reasons such as the base station want to update the multicast configuration, the base station wants to transfer all idle state or inactive state terminals to a connection state to receive the multicast service, for example, the base station includes the multicast service identifier in the paging message, but does not include the packet identifier, and the paging message also includes the multicast configuration update indication.

4. After receiving the paging message, the terminal finds that the paging message does not contain a packet identifier, and additionally, the terminal finds that the paging message contains a multicast configuration update instruction, and then the terminal 1, the terminal 2, the terminal 3 and the terminal 4 initiate state transition, and continue to receive the multicast service after entering the connection state update multicast configuration.

Example 6

2. For reasons such as the base station want to update the multicast configuration, the base station wants to transfer all idle state or inactive state terminals to a connection state to receive the multicast service, for example, the base station includes the multicast service identifier in the paging message, but does not include the packet identifier, and the paging message also includes the multicast configuration update indication.

3. After receiving the paging message, the terminal finds that the paging message does not contain a packet identifier, and additionally, the terminal finds that the paging message contains a multicast configuration update instruction, and then the terminal 1, the terminal 2, the terminal 3 and the terminal 4 initiate state transition, and continue to receive the multicast service after entering the connection state update multicast configuration.
