The message sending method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 2 shows a flowchart of a message sending method provided in an embodiment of the present application, where the method 200 may be executed by a terminal, in other words, the method may be executed by software or hardware installed in the terminal. As shown in fig. 2, the method may include the following steps.
S201, performing cell reselection and residing in the first cell.
And when the terminal meets the cell reselection rule of the mobility management rule of the network, executing cell reselection operation, and reselecting and residing to the first cell from other cells.
In this embodiment, the terminal may perform cell reselection in a non-radio access control connected state, that is, the terminal is in an RRC-IDLE or RRC-Inactive state.
S202, sending a first signaling message to a network side, wherein the first signaling message is used for establishing, activating or modifying data transmission resources of a first service.
In this embodiment, the terminal is a terminal interested in a first service, and in order to maintain continuity of the first service in the first cell, the terminal sends a first signaling message to a network side. Through the first signaling message, the terminal can establish, activate or modify data transmission resources for performing the first service with the network side.
In one implementation, the first service may belong to any service type, and also includes: broadcast multicast service (MBS) service. Further, the first service may be any MBS service, and equivalently, the Temporary Mobile Group Identity (TMGI) serving as the identifier of the MBS service may be any value.
In one implementation, the first cell where the terminal is reselected to camp on may be any cell that satisfies a cell reselection rule, and the first cell may be any one of the following according to whether the first cell has a capability of a service type corresponding to the first service, and whether the first cell provides the first service:
a cell having a capability of a service type corresponding to the first service and providing the first service;
a cell that does not have the capability of a service type corresponding to the first service but provides the first service;
a cell having a capability of a service type corresponding to the first service but not providing the first service;
the method comprises the steps of not having the capability of the service type corresponding to the first service and not having a cell providing the first service.
It should be understood that the above "providing the first service" means that the first cell currently configures corresponding resources for the first service; the "not providing the first service" means that the first cell does not currently configure corresponding resources for the first service.
It should be understood that the first cell is a cell having a capability of a service type corresponding to a first service, and refers to a cell to which the first cell is a base station having a capability of a corresponding service type, for example, if the first service belongs to an MBMS (or MBS) service, the first cell is a cell to which a base station RAN node having an MBMS (or MBS) capability belongs, that is, data of the MBMS (or MBS) may be transmitted in a shared delivery (shared delivery) manner through a core network part.
The first cell is a cell that does not have a capability of a service type corresponding to the first service, and means that the first cell is a cell to which a base station that does not have the capability of the corresponding service type belongs, for example, if the first service belongs to an MBMS (or MBS) service, the first cell is a cell to which a base station (Radio Access Network (RAN) node) that does not have the MBMS (or MBS) capability belongs, that is, the base station may not transmit data of the MBMS (or MBS) in a shared delivery (shared delivery) manner through a core Network part.
It should be understood that the first cell is a cell providing a first service, for example, if the first service is an MBS service with TMGI ═ x, the first cell may provide the MBS service with TMGI ═ x in a Point-to-Point (PTP) and/or Point-to-multipoint (PTM) manner of shared transmission (shared transmission), or in a Protocol Data Unit (PDU) session (session) manner.
The first cell is a cell that does not provide the first service, which means that the first cell does not currently configure corresponding resources for the first service.
It should be understood that the first signaling message sent by the terminal to the base station may be sent in many ways, and may be a Non Access Stratum (NAS) signaling message, such as a Service Request (Service Request).
The first signaling message sent by the terminal to the base station may also be a Radio Resource Control (RRC) signaling message. For example, for MBS services, the first signaling message may be an MBS-related RRC message of interest.
In a possible implementation manner, the first signaling message further carries identification information of the first service. Through the possible implementation manner, the network side can acquire the first service which the terminal wants to continue to transmit.
In another possible implementation manner, the first signaling message carries identification information of the terminal or identification information of a terminal user. In this possible implementation manner, the network side may determine, according to the identification information of the terminal or the identification information of the terminal user, whether the terminal or the terminal user has previously joined a session of a certain first service, so as to determine the first service that needs to be continuously transmitted to the terminal.
In the foregoing possible implementation manner, optionally, before S201, the method may further include: a session join procedure for the first service is performed. That is, in this possible implementation, the terminal performs cell reselection after joining the session for the first service.
In a possible implementation manner, if the terminal performs cell reselection in the non-connected state, optionally, when the first message signaling is sent, the terminal may enter the connected state and then send the signaling message. For example, the terminal may transmit the first message signaling by performing an RRC connection setup procedure or an RRC recovery procedure.
Alternatively, the terminal may also send the first signaling message in a non-connected state. That is, the terminal may directly transmit the first signaling message in a non-connected state. For example, the first signaling message may be sent in an Early Data Transmission (EDT) manner of an LTE Control Plane/User Plane (CP/UP), or in a Predefined Uplink Resource (PUR) manner of an LTE ecp/UP, or in a Small Data Transmission (NR SDT) manner.
In one possible implementation manner, after S202, the method may further include: and receiving the first service according to the data transmission resource configured by the network side. That is, in this possible implementation, the UE may continue to receive the first service according to the resources configured by the network.
In the foregoing possible implementation manner, the data transmission resource configured by the network side includes at least one of:
(1) PDU session resources;
(2) multicast session resources. For example, N3 tunnel (tunnel) resources and/or scheduling resources on the RAN side, for example, a RAN node may transmit MBS service with TMGI ═ x to the UE using PTP resources of MBS shared transmission (shared delivery).
Therefore, in the message sending method provided by the embodiment of the application, the terminal performs cell reselection to camp on the first cell; and sending a first signaling message to a network side, wherein the first signaling message is used for establishing, activating or modifying data transmission resources of the first service, so that the terminal maintains the continuity of the first service after finishing cell reselection and residence.
Fig. 3 is a schematic flow chart of a message sending method according to an embodiment of the present application, and as shown in fig. 3, the method 300 may include the following steps.
S301, cell reselection is executed to reside in the first cell.
The step S301 may adopt the same or similar descriptions as step S201 in the embodiment of fig. 2, and is not repeated herein to avoid repetition.
S302, when a first condition is met, sending a first signaling message, wherein the first signaling message is used for establishing, activating or modifying data transmission resources of a first service.
In an embodiment, after reselecting to camp on the first cell, the terminal needs to send the first signaling message to the network side only when a first condition is met. The first condition may be any one combination of the following:
the terminal is interested in the first service;
the terminal has the capability of the service type corresponding to the first service, for example, if the first service belongs to the MBS service, the terminal UE may generate and receive signaling and user data related to the MBS service.
The first cell is included in a service area of the first service, for example, the first service is a local service (i.e., service is only possible in the service area), and the first cell belongs to the service area of the first service;
the terminal reselects from other cells except the first cell to camp on the first cell;
the terminal cannot acquire information of the first service or data of the first service in the first cell, for example, if the first service belongs to an MBS service with TMGI ═ x, the terminal cannot acquire scheduling information of the MBS service with TMGI ═ x;
the terminal cannot acquire a capability indication of the first cell, wherein the capability indication indicates that the first cell has or does not have the capability of the service type corresponding to the first service; this part is consistent with the explanation of S202 and will not be described in detail.
The terminal is allowed to send the first signaling message, for example, the terminal is indicated in a system message received by the terminal to be allowed to send the first signaling message, for example, a timer can be configured for the terminal through the system message, the terminal is required to start timing by using the timer when receiving the system message, and the terminal sends the first signaling message after the timer is not timed out or is timed out.
It should be understood that the first signaling message sent by the terminal to the base station may be sent in many ways, and may be a Non Access Stratum (NAS) signaling message, such as a Service Request (Service Request).
The first signaling message sent by the terminal to the base station may also be a Radio Resource Control (RRC) signaling message. For example, for MBS services, the first signaling message may be an MBS-related RRC message of interest.
It should be noted that, in this embodiment, differences from the embodiment of the method 200 in this embodiment are mainly described, and other related contents may refer to the description in the embodiment of the method 200, which is not described herein again.
Therefore, in the message sending method provided by the embodiment of the present invention, the terminal performs cell reselection to camp on the first cell; when the first condition is met, sending a first signaling message to the network side, and setting the corresponding first condition according to the actual situation, so that the terminal keeps the continuity of the first service and reduces unnecessary signaling consumption when the first condition is met after finishing cell reselection and residence.
Fig. 4 is a schematic flow chart of a message sending method provided in an embodiment of the present application, and as shown in fig. 4, the method 400 may include the following steps.
S401, executing the session joining process of the first service. For example, the multicastessionjoin process
S402, executing cell reselection and residing in a first cell;
s403, when the first condition is satisfied, the first signaling message is sent to the network side.
The steps S402 and S403 may adopt the same or similar descriptions as the steps S301 and S302 in the embodiment of fig. 3, and the same or similar parts are not described herein again to avoid repetition.
In one embodiment, if the terminal has executed the session joining procedure of the first service during the time of camping in another cell, in step S403, when the terminal sends the first signaling message to the network side, the first signaling message may not carry the identification information of the first service, but only carry the identification information of the terminal or the identification information of the terminal user. For example, if the first service is an MBS service with TMGI ═ x, the terminal has already performed a Session Join Session procedure for the MBS service with TMGI ═ x. After receiving the first signaling message, the core network device may search the first service from the information of the session joining process of the first service executed by the terminal according to the identification information of the terminal or the identification information of the terminal user, and further reasonably allocate resources for the first service.
In another embodiment, the first signaling message sent by the terminal to the network side may carry identification information of the first service. For example, for MBS services, the first signaling message may carry the value of the TMGI.
It should be understood that, in the present embodiment, differences from the embodiment of the method 200 in the present embodiment are mainly described, and other related contents may refer to the description in the embodiment of the method 200, which is not described herein again.
For example, there are many ways for the terminal to transmit the first signaling message to the base station, and the first signaling message may be a Non Access Stratum (NAS) signaling message, such as a Service Request (Service Request).
The first signaling message sent by the terminal to the base station may also be a Radio Resource Control (RRC) signaling message. For example, for MBS services, the first signaling message may be an MBS-related RRC message of interest.
Therefore, according to the message sending method provided by the embodiment of the present invention, before performing cell reselection and camping on a first cell, a session joining process of the first service is performed; the terminal does not need to carry the identification information of the first service when sending the first signaling message, so that the terminal keeps the continuity of the first service and reduces unnecessary signaling consumption when meeting the first condition after finishing cell reselection and residence.
In an embodiment, after performing cell reselection camping on a first cell, the terminal may send the first signaling message to the network side in a non-connected state, that is, when the UE is in a non-active state RRC-Inactive or Idle state Idle, for example, the first signaling message may be sent by an Early Data Transmission (EDT) mode of an LTE Control Plane/User Plane (CP/UP), or may be sent by a Preconfigured Uplink Resource (PUR) mode of an LTE CP/UP, or may be sent by an NR SDT (Small Data Transmission) mode.
In another embodiment, after performing cell reselection camping on a first cell, the terminal may send the first signaling message to the network side in a Connected state (CM-Connected) state, that is, after performing cell reselection camping on the first cell, the terminal first performs an RRC connection establishment procedure or an RRC connection recovery procedure, so that the terminal enters a Connected state from an unconnected state, and then sends the first signaling message.
Therefore, according to the message sending method provided by the embodiment of the invention, the terminal can select to send the first signaling message in the connected state or the unconnected state, so that the terminal can flexibly select a mode of sending the first signaling message after finishing cell reselection and residence, and continuity of the first service is maintained.
Fig. 5 is a schematic flow chart of a message sending method provided in an embodiment of the present application, and as shown in fig. 5, the method 500 may include the following steps.
Step S501, executing cell reselection and residing in a first cell;
step S502, when the first condition is satisfied, the first signaling message is sent to the network side.
Each possible implementation manner of the steps S501 and S502 may adopt various possible implementation manners with the same or similar contents as those in the steps S402 and S403 in the embodiment of fig. 4, and details are not repeated here to avoid repetition.
Step S503, receiving the first service according to the data transmission resource configured by the network side.
In an embodiment, after receiving the first signaling message, the network side device configures, according to the determined first service, a data transmission resource for executing the first service for the terminal, so that the terminal can receive the relevant information and data of the first service according to the data transmission resource, so as to maintain the continuity of the first service for the terminal.
It should be understood that the data transmission resource configured by the network side is configured by the network side according to actual situations, and includes: and configuring data transmission resources according to the fact that the first cell is a cell with or without the capacity of the service type corresponding to the first service, and/or the first cell is a cell providing or not providing the first service.
The data transmission resource configured by the network side may be a PDU session resource. For example, if the base station to which the first cell belongs is a base station that does not have the capability of broadcasting a multicast service MBS-capable, the core network device will establish a PDU session resource with the base station.
Alternatively, the data transmission resource configured on the network side may also be a multicast session resource, for example, an MBS session resource.
It should be noted that, in this embodiment, differences from the embodiments of the method 200 and the method 300 in this embodiment are mainly described, and other related contents may refer to the description in the embodiments of the method 200 and the method 300, and are not described herein again.
Therefore, in the message sending method provided by the embodiment of the present invention, the cell is reselected to camp on the first cell; when a first condition is met, sending the first signaling message; and receiving the first service according to the data transmission resource configured by the network side, so that the terminal can keep the continuity of the first service.
It should be noted that, in the message sending method provided in the embodiment of the present application, the execution main body may be a message sending apparatus, or a control module in the message sending apparatus for executing the message sending method. In the embodiment of the present application, a method for a message sending apparatus to perform communication is taken as an example, and the message sending apparatus provided in the embodiment of the present application is described.
