Detailed Description

To make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

In order to solve the problem that when receiving an MBS, a unified receiving mechanism is adopted for the same serving cell and cannot adapt to the cell service conditions and different feedback requirements of different MBS for the same serving cell in the prior art, embodiments of the present invention provide a method for receiving a multicast broadcast service MBS, which provides a preconfigured information for a terminal, where the preconfigured information defines a corresponding receiving mode when the terminal is in an idle state or an inactive state, so as to determine the receiving mode of the MBS according to feedback requirements of the MBS, busy/idle degree or congestion degree of the cell, and other conditions.

An MBS receiving method according to an embodiment of the present invention is applied to a terminal, and as shown in fig. 1, the method includes:

s110, acquiring pre-configuration information; the pre-configuration information defines a receiving mode for receiving the MBS when the terminal is in an idle state or an inactive state;

and S120, when the terminal is in an idle state or an inactive state, receiving the MBS according to the receiving mode defined by the pre-configuration information.

By adopting the MBS receiving method of the embodiment of the invention, the conditions that different MBS have different requirements on feedback due to different QoS, and the conditions that the number of the current connected state UE of a cell or the congestion degree are considered, and corresponding to different conditions, the network side can adopt different modes to send the MBS, so that the corresponding receiving mode during the MBS receiving can be defined by the pre-configuration information to help the idle state or non-activated state UE to efficiently receive the interested MBS, thereby achieving the purposes of reducing the occupation of broadcast resources and improving the quality of the MBS received by the UE.

Optionally, at least two different receiving modes corresponding to MBS receiving are defined in the pre-configuration information.

Optionally, the manner for receiving MBS for the terminal in idle or inactive state includes but is not limited to only being able to include the following three types:

the first mode is as follows: the base station broadcasts and receives the information of the control channel and/or the service channel of the MBS, so that the UE can broadcast the resources appointed by the message to receive the MBS without entering a connection state;

the second mode is as follows: after initiating a Radio Resource Control (RRC) connection establishment procedure and entering a connection state, the UE receives the MBS through a Point-To-Point (PTP) or Point-To-Multipoint (PTM) manner.

A third mode: the UE first enters a connected state to receive Control information of the MBS, such as an MBS Control Channel (MCCH), and then returns to an idle/active state to receive service information of the MBS.

The three different MBS reception modes have different advantages and disadvantages. For example, for the first mode, the disadvantage is that more broadcast resources are occupied, and since the UE is in idle/inactive state and cannot perform feedback, the network side cannot perform effective service retransmission, and the efficiency of MBS transmission or QoS effect is not good; for the second mode, the advantage is that the UE can feed back the received service condition, which can ensure the QoS transmission performance of the service, but the disadvantage is that the UE must enter the connected state, introduce a more complicated flow, the power consumption of the terminal is also larger, and when a large number of terminals enter the connected state at the same time, congestion of the cell may be caused; for the third mode, the method has the advantages that the receiving quality of the control channel can be guaranteed, and the power consumption of the UE can be saved to a certain extent; however, the UE still returns to idle/inactive state that cannot be fed back when receiving MBS, and thus, the quality of service reception cannot be guaranteed.

According to the different advantages and disadvantages of the three different modes, the MBS receiving method of the embodiment of the invention defines different receiving modes for different services by using the pre-configuration information so as to adapt to the problems of the cell service condition and different feedback requirements of different MBS.

For example, the preconfigured information is receiving modes respectively defined for different MBS, including:

the first MBS is sent in a broadcast mode, and the UE receiving the first MBS completes the receiving of the first MBS by receiving the broadcast message in an idle or inactive state; the second MBS enters a connected state through the UE and then receives the data; the UE receiving the third MBS needs to enter the connection state to receive the control information of the MBS first and then returns to the idle or inactive state to receive the service information of the MBS.

Optionally, the MBS receiving method includes obtaining the pre-configuration information in at least one of the following manners:

defined in a protocol;

transmitted by the base station through broadcast messages;

the core network informs the base station, which informs the terminal through a non-access stratum NAS message.

It should be noted that the preconfigured information may be provided to the terminal in one of the three manners, or in a combination of at least two manners.

For example, the receiving mode of a part of MBS may be defined by a protocol, the operator defines the receiving mode of a part of MBS, and then provides the other part of MBS through a broadcast message or NAS information, and the three modes combine to provide the receiving modes of a plurality of different MBS to the terminal.

Optionally, the preconfigured information comprises at least one of:

the probability that the terminal enters a connected state from an idle state or an inactive state to receive the MBS is obtained;

when the terminal is in the idle state or the inactive state, in step S120, the receiving of the MBS is performed according to the receiving manner defined by the preconfigured information, including:

and receiving the MBS by adopting the receiving mode.

Wherein, determining the receiving mode adopted by MBS reception according to one or at least two of the receiving mode, the channel quality threshold, the target parameter condition and the probability indicated in the pre-configuration information includes one of the following:

and when determining that the receiving mode adopted by the MBS receiving is the entering connection state according to any mode, determining whether the final receiving mode is the entering connection state or not by taking the probability as a constraint condition.

According to the above, by adopting the method of the embodiment of the present invention, the receiving mode of the MBS service reception can be determined according to one of the receiving mode, the channel quality threshold, and the target parameter condition indicated in the pre-configuration information; optionally, at least one of the channel quality threshold, the target parameter condition, and the probability may be respectively used as constraint conditions, and the receiving method adopted by the MBS is determined according to the receiving method indicated in the pre-configuration information, where when the state of the terminal satisfies the constraint conditions, it is determined that the indicated receiving method may be adopted, and when the constraint conditions are not satisfied, it is determined that the indicated receiving method cannot be adopted.

It should be noted that the determination method of the MBS reception scheme listed above is only for example, and is not limited to this specific.

In an embodiment of the present invention, optionally, the target receiving manner includes at least one of a first receiving manner, a second receiving manner, and a third receiving manner; wherein,

when the target receiving mode comprises a second receiving mode, the channel quality is less than or equal to a second quality threshold;

the first receiving mode is that the terminal receives the MBS in an idle state or an inactive state, which corresponds to the first mode;

the second receiving mode is that the terminal enters a connection state to receive the MBS, namely corresponds to the second mode;

the third receiving mode is that the terminal in the idle state or the inactive state firstly enters the connection state to receive the control information and then returns to the idle state or the inactive state to receive the MBS; that is, the third embodiment described above.

It should be noted that, when the target receiving manner includes a third receiving manner, the channel quality is located between the first quality threshold and the second quality threshold, that is, the channel quality is smaller than the first quality threshold and greater than the second quality threshold, or the channel quality is smaller than or equal to the first quality threshold and greater than or equal to the second quality threshold.

Wherein the second quality threshold is less than the first quality threshold.

In this embodiment, the pre-configuration information may indicate a quality threshold when receiving the MBS service in at least one of the three receiving manners.

In an embodiment of the present invention, in another implementation, the target receiving manner includes at least one of a first receiving manner and a second receiving manner; wherein,

In this embodiment, the pre-configuration information may indicate a quality threshold when receiving the MBS service in at least one of the two receiving manners, that is, indicate a quality threshold when receiving the MBS service in any two of the three manners.

In an embodiment of the present invention, optionally, the pre-configuration information includes MBS supported by the cell and a receiving mode corresponding to the supported MBS.

Specifically, the MBS supported by the cell and the corresponding idle or inactive terminal receiving manner of the MBS, which are broadcasted in the pre-configuration information, include at least one of the first receiving manner to the third receiving manner.

The method determines the supported MBS and the receiving mode corresponding to the MBS service through at least one of broadcasting, protocol agreement, core network notification and the like, can determine the sending mode of the MBS in real time according to the cell service condition, and provides the receiving mode corresponding to the MBS to the terminal so as to improve the quality of receiving the MBS by the UE.

In another embodiment, the preconfigured information includes:

and receiving the channel quality threshold when the target MBS is received by adopting a target receiving mode.

The channel Quality threshold of the Receiving target MBS includes, but is not limited to, a threshold capable of only including at least one of Reference Signal Receiving Power (RSRP), reference Signal Receiving Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR), and the threshold is used to implicitly indicate a requirement that the UE receives the MBS in an idle state or an inactive state in a corresponding Receiving manner.

Optionally, the indicated channel quality threshold when the target receiving mode receives the MBS includes: for the target MBS, the terminal adopts the channel quality when the first mode is adopted for receiving in an idle state or an inactive state; for the target MBS, the terminal adopts the channel quality when receiving in the second mode in an idle state or an inactive state; for the target MBS, the terminal adopts the channel quality when receiving in the third mode in the idle state or the inactive state.

For example: according to the channel quality indicated by the pre-configuration information when the target MBS is received in the target receiving manner, for a first MBS, the pre-configuration information may indicate that a measurement value of the channel quality of the UE (for example, at least one of RSRP, RSRQ, and SINR) is higher than or equal to a first threshold (indicating that the cell signal quality received by the UE is good, and the UE can substantially successfully receive a service without feedback and retransmission), and the UE may receive the first MBS in an idle state or an inactive state, that is, receive the first MBS in the first manner;

the pre-configuration information may further indicate that a measurement value of channel quality (e.g., at least one of RSRP, RSRQ, and SINR) of the UE is lower than or equal to a second threshold (indicating that the quality of a cell signal received by the UE is poor, it is difficult to successfully receive a service once, and feedback and retransmission are required), and the UE needs to enter a connected state to receive the first MBS, that is, receive the first MBS through a second method;

the pre-configuration information may also indicate that when the measurement value of the channel quality of the UE is between the first threshold and the second threshold, the UE first enters the connection state to receive the control information, and then returns to the idle state or the inactive state to receive the first MBS, that is, receives the first MBS through the third method.

It should be noted that the receiving method when the channel quality is preset, indicated in the preconfiguration information, is not limited to be only one of the three methods, and for example, the terminal may be indicated to be capable of adopting two of the three methods, or the terminal may decide to receive the first MBS.

In another embodiment, the provisioning information includes:

alternatively, the target parameter conditions include, but are not limited to, being able to include only speed conditions and/or channel quality conditions, etc.

Wherein the speed condition may include that the moving speed of the terminal is less than or equal to a preset speed threshold, and the channel quality condition may include that the measured value of the channel quality is higher than or equal to a predetermined threshold.

When the terminal is in an idle state or an inactive state, if the receiving speed is lower than or equal to the speed threshold and/or the channel quality (including at least one of RSRP, RSRQ and SINR) of the terminal is higher than or equal to a predetermined threshold, indicating that the signal quality of the UE is better and/or the mobility is slower, the terminal can receive the MBS in the idle state or the inactive state; in other cases, the terminal needs to enter a connected state to receive the MBS.

In another embodiment, the provisioning information includes:

In order to reduce congestion caused by the fact that the UE with excessive quantity simultaneously enters the connected state to receive the MBS, the base station broadcasts the probability P of entering the connected state to receive the MBS, so that the UE generates a random number P according to the probability P when needing to enter the connected state to receive the MBS, the random number P is compared with the P in the pre-configuration information, and when the P is smaller than or equal to the P, the UE can enter the connected state to receive the MBS; otherwise, waiting for entering the time of receiving the MBS in the connection state, or receiving the MBS by adopting other modes.

Optionally, the random number p generated by the terminal is a value between 0 and 1, i.e. greater than or equal to 0 and less than or equal to 1.

Optionally, the probability indicated in the pre-configuration information may be applicable to all MBS received by the terminal, or may be applicable to partial MBS, or correspond to different MBS, and respectively indicate corresponding different probabilities.

Optionally, according to the probability indicated in the pre-configuration information, the probability may be combined with the receiving manner defined in the pre-configuration information and the above-mentioned at least one condition for determining the receiving manner indicated in the pre-configuration information, so as to further determine the manner in which the terminal receives the MBS in the idle state or the inactive state. For example, the probability is combined with any two conditions described above, or at least three conditions, to determine the manner of receiving the MBS. For example, when it is determined that the UE currently enters the connected state to receive the MBS according to the moving speed and/or the quality information of the terminal, the UE further generates a random number, optionally, the random number is less than 1 or greater than or equal to 0, and when the generated random number is less than or equal to the probability, it is determined that the terminal can immediately enter the connected state; if the probability is larger than or equal to the probability, the UE needs to wait for a period of time T (the T can be predefined by a protocol and can also be notified to the UE by a base station broadcast message), and then a random number is generated again for judgment; or the UE receives the MBS in idle or inactive state.

Therefore, in this embodiment of the present invention, optionally, when the preconfigured information includes a probability that the terminal enters a connected state from an idle state or an inactive state to receive the MBS, determining a receiving manner used by MBS reception according to the preconfigured information includes:

after determining the MBS to be received, generating a random number when the receiving mode adopted by the MBS is to enter a connection state from an idle state or an inactive state;

when the random number is less than or equal to the probability, determining that the final receiving mode of the MBS to be received is connected state receiving; or

When the random number is greater than or equal to the probability, waiting for a preset time length, generating the random number again, comparing the random number with the probability until the generated random number is less than the probability, and determining that the final receiving mode is receiving in a connection state; or alternatively

And when the random number is greater than the probability, waiting for a preset time length, generating the random number again, comparing the generated random number with the probability until the generated random number is less than or equal to the probability, and determining that the final receiving mode is receiving in a connection state.

In the MBS receiving method according to the embodiment of the present invention, through the above pre-configuration information, the receiving mode of the determined MBS service satisfies at least one of the following conditions:

determining according to the MBS supported by the cell and the receiving mode corresponding to the supported MBS;

determining according to the current channel quality of the terminal and the channel quality threshold indicated in the pre-configuration information when receiving the target MBS by adopting a target receiving mode;

the determined receiving mode of the MBS is that when the MBS is received in an idle state or an inactive state, the current target parameter of the terminal meets the target parameter condition indicated in the pre-configuration information;

when the determined MBS is received from an idle state or an inactive state to a connected state, the random number generated by the terminal is less than or equal to the probability indicated by the pre-configuration information.

Therefore, by adopting the MBS receiving method according to the embodiment of the present invention, the terminal in the idle state or the inactive state determines the receiving mode for receiving the MBS according to the pre-configuration information and the MBS service to be received.

Optionally, at least one of the conditions defined in the pre-configuration information may determine the receiving mode of the MBS; optionally, the conditions defined in the pre-configuration information may be combined with each other to determine the receiving mode of the MBS. For example, in one embodiment, the receiving mode of the MBS is determined by combining the channel quality when the target receiving mode is used to receive the target MBS indicated in the pre-configuration information and the probability that the terminal enters the connected state from the idle state or the inactive state to receive the MBS, where the receiving mode of the MBS is determined such that the UE should enter the connected state to receive the MBS when the measured values of RSRP, RSRQ, and/or SINR of the UE are lower than or equal to a second threshold (the second threshold indicates that the quality of a cell signal received by the UE is poor, it is difficult to successfully receive a service at a time, and feedback and retransmission are required); however, since the serving cell is already somewhat congested, the base station broadcasts the probability P (for all MBS or MBS interested by UE), then the UE further generates a random number P, if P is less than or equal to P, then whether to immediately enter a connected state to receive MBS; otherwise, the UE continues to receive the MBS in idle or inactive state.

In another embodiment, the determining the receiving mode of the MBS, in combination with the target parameter condition that the terminal indicated in the pre-configuration information can receive the MBS in the idle or inactive state, the channel quality when the target receiving mode is used to receive the target MBS, and the probability that the terminal enters the connected state from the idle or inactive state to receive the MBS, may be:

when receiving the first MBS service, when the UE speed is higher than a preset speed threshold, and/or the RSRP or RSRQ or SINR measurement value of the UE is lower than or equal to a second threshold, indicating that the UE moves faster and/or the signal quality is poor, the UE should enter a connection state for receiving; however, because the service cell is already congested, the base station broadcasts the probability P (for all MBS or the first MBS interested by the UE), then the UE further generates a random number P, if P is less than or equal to P, the UE can immediately enter a connection state to receive the first MBS service; otherwise, the UE continues to receive the first MBS in idle or inactive state. It should be noted that, the determination of the MBS receiving type according to the preconfigured information and the MBS receiving type is only an example, and is not limited thereto, and the determination of the MBS receiving type according to any condition or a combination of at least two conditions may include multiple ways, which are not described in detail herein.

By adopting the MBS receiving method of the embodiment of the invention, the MBS sending and receiving mode is determined according to the feedback requirement of the MBS and the busy or idle or congestion degree of the cell, thereby helping the UE in an idle state or an inactive state to efficiently receive the interested MBS, reducing the occupation of broadcast resources and improving the quality of the MBS received by the UE.
