For the convenience of understanding, some contents involved in the embodiments of the present application are described below:

Multimedia Broadcast Multicast Service (MBMS), hereinafter referred to as multicast service.

In the LTE system, multicast services can be transmitted through multicast/multicast single frequency network (Multicast Broadcast Single Frequency Network, MBSFN) and single-cell point-to-multipoint (Single-Cell Point-to-Multipoint, SC-PTM) two kinds way to send.

1. MBSFN mode: It is equivalent to receiving the same data through multiple paths. It is transmitted through a Physical Multicast Channel (PMCH) in an MBSFN subframe. Both control information and data information of the MBMS service are sent in a broadcast manner, so that both the idle (idle) state UE and the connected state UE can receive the MBMS service, and the MBMS data information is only sent in the MBSFN subframe. The control information related to the multicast service is sent through system information and a broadcast control channel (Multicast Control Channel, MCCH), and the data is sent through a broadcast service channel (Multicast Traffic Channel, MTCH). The control information of the MBMS service may include control channel parameters, service channel parameters, scheduling information, etc., and the control information may be sent in a system information block (System Information Block, SIB) 13 .

2. SC-PTM mode: sent through a physical downlink control channel (Physical Downlink Shared Channel, PDSCH) scheduled by a physical downlink control channel (Physical Downlink Control Channel, PDCCH). Wherein, the control information is sent through the system information (such as SIB20) and the single cell broadcast control channel (Single Cell Multicast Control Channel, SC-MCCH), and the data is sent through the single cell broadcast service channel (Single Cell Multicast Traffic Channel, SC-MTCH). Among them, SC-MCCH is sent through PDSCH scheduled by single-cell wireless network temporary identity (SC Radio Network Temporary Identity, SC-RNTI) PDCCH, and SC-MTCH is scheduled by group wireless network temporary identity (Group RNTI, G-RNTI) PDCCH PDSCH transmission.

In a new air interface (New Radio, NR), it is expected to support the continuity of multicast service data during cell handover, for which the handover processing method of the present application is proposed. Among them, cell handover can be understood as mobile handover.

The handover processing method provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Please refer to FIG. 2. FIG. 2 is a flowchart of a handover processing method provided by an embodiment of the present application. The method is applied to a source base station, as shown in FIG. 2, and includes the following steps:

Step 201, providing multicast service information to the target base station based on the target information of the target base station;

In the embodiment of the present application, the source base station may be understood as the current serving base station of the terminal, and the target base station refers to the target base station that performs the handover of the terminal during the handover process. For the cell handover procedure, the terminal may be handed over from the source cell to the target cell. The above-mentioned source base station may be understood as a network device in the source cell, and the above-mentioned target base station may also be understood as a network device in the target cell.

The above-mentioned multicast service information may be understood as: the multicast service being received by the terminal or the multicast service information corresponding to the multicast service that the terminal is interested in.

For example, in the process of receiving a multicast service for a certain terminal, when the source base station decides the handover operation of the terminal, the source base station can select the target base station, and can provide the target base station with the target base station based on the target information of the target base station. Receive multicast service information for multicast services. Therefore, the terminal can be assisted to establish the multicast service connection after handover to the target base station, so as to realize the continuity of the multicast service.

The manner in which the source base station selects the target base station may be set according to actual needs. For example, in an embodiment, it may be based on a measurement report reported by the terminal, or based on candidate cell information, or may be independently selected.

It should be understood that the above target information of the target base station may be obtained by the source base station before handover, for example, obtained through interaction between the source base station and the target base station. Exemplarily, the source base station and the target base station may interact through the Xn interface to obtain target information of the target base station.

It should be noted that the content contained in the above-mentioned multicast service information may be set according to actual needs. For example, in an embodiment, the above-mentioned multicast service information includes a multicast service identifier. The multicast service identifier may be a temporary mobile group identity (Temporary Mobile Group Identity, TMGI) or a data flow identity (QoS flow identity, QFI).

Optionally, in an embodiment, the multicast service information may further include quality of service (Quality of Service, QoS) requirement information corresponding to the multicast service identifier.

Optionally, the base station types include a first type of base station and a second type of base station; wherein the first type of base station is a base station that can provide multicast services through multicast, and the second type of base station is a base station that cannot use multicast services. A base station that provides multicast services in broadcast mode.

In this embodiment, the base station of the first type may be called a multicast base station, and the base station of the second type may be called a traditional base station or a non-multicast base station. In this embodiment, the above-mentioned source base station should be understood as a multicast base station. The above multicast mode can be understood as providing a multicast service by establishing a shared channel with the core network base station.

It should be understood that the above target information is used to determine whether to send the multicast service information to the target base station. For different target information, the conditions for meeting the sending of multicast service information are also different. That is, in this embodiment of the present application, the source base station may determine whether to provide multicast service information to the target base station in different ways based on different target information. For example, in an embodiment, the providing multicast service information to the target base station based on the target information of the target base station includes at least one of the following:

When the target information includes a base station type, and the base station type is a first type of base station, provide multicast service information to the target base station, where the first type of base station is capable of providing multiple base station for broadcasting services;

In the case that the target information includes supported service information, and the service corresponding to the supported service information includes the target service, providing multicast service information to the target base station;

In the case that the target information includes unsupported service information, and the service corresponding to the unsupported service information does not include the target service, provide multicast service information to the target base station;

In the case that the target information includes load information, and it is determined based on the load information that the radio resources of the target base station are sufficient to reserve air interface resources for the target service, providing multicast service information to the target base station;

Wherein, the target service is the multicast service being received by the terminal or the multicast service that the terminal is interested in.

The above load information may be understood as the load status of the target terminal, for example, may include the use status of the radio resources of the target base station, the number of users served by the target base station, and the like.

For the above base station types, if the target base station is a multicast base station, the source base station provides multicast service information to the target base station; if the target base station is a traditional base station, the source base station does not provide multicast service information to the target base station. That is to say, when the target information includes the base station type, the source base station providing multicast service information to the target base station needs to satisfy the first condition: the target base station is a multicast base station.

For the supported service information and the unsupported service information, when the target information includes at least one of the supported service information and the unsupported service information, the source base station may determine, based on the target information, the target multicast service being received by the terminal or the terminal Whether the target multicast service of interest is the multicast service supported by the target base station. If the target multicast service is a multicast service supported by the target base station, the source base station provides multicast service information to the target base station; if the target multicast service is a multicast service not supported by the target base station, the source base station does not provide the target base station with multicast service information. Provides multicast service information. That is to say, when the target information includes at least one of supported service information and unsupported service information, the source base station providing multicast service information to the target base station needs to satisfy the second condition: the target multicast service being received by the terminal or the The target multicast service that the terminal is interested in is the multicast service supported by the target base station.

As an example, the multicast service being received by the terminal is multicast service 1 and multicast service 2, wherein the multicast service 1 is a multicast service supported by the target base station, and the multicast service 2 is not supported by the target base station The source base station only provides the multicast service information corresponding to the multicast service supported by the target base station, that is, only provides the multicast service information corresponding to the multicast service 1.

For the above load information, the source base station can determine, based on the load information, whether the radio resources of the target base station are sufficient to reserve air interface resources for the target multicast service received by the terminal at the source base station or the target multicast service that the terminal is interested in. If it is determined that the radio resources of the target base station are insufficient to reserve air interface resources for the target multicast service, the multicast service information is not provided to the target base station; if it is determined that the radio resources of the target base station are sufficient to reserve air interface resources for the target multicast service, the The base station provides multicast service information. That is to say, when the target information includes load information, the source base station to provide the target base station with multicast service information needs to satisfy the third condition: the radio resources of the target base station are sufficient for the target multicast service being received by the terminal or the target that the terminal is interested in. Multicast services reserve air interface resources.

As an example, the multicast service that the terminal is receiving is multicast service 1 and multicast service 2, and the radio resources of the target base station can only reserve air interface resources for one multicast service, and the terminal only provides multiple multicast services corresponding to one multicast service. The multicast service information, for example, the multicast service information corresponding to the multicast service 1 is provided. The source base station can arbitrarily choose which or which multicast service multicast service information to provide to the target base station, that is, the source base station can provide multicast service information corresponding to multicast service 1 to the target base station, and can also provide multicast services. 2. The corresponding multicast service information is sent to the target base station, and the specific behavior depends on the implementation of the base station. As another example, the source base station may determine which multicast service information or information to provide to the target base station according to the QoS information corresponding to the multicast service. For example, the delay requirement corresponding to the multicast service 1 is smaller than that of the multicast service 2. demand, the source base station provides the target base station with multicast service information corresponding to the multicast service with small delay demand.

It should be noted that the above terminal handover may include an Xn handover scenario and an N2 handover scenario, and for different handover scenarios, the corresponding source base station provides multicast service information to the target base station in different ways.

For the Xn handover scenario, the source base station can directly provide multicast service information to the target base station.

For the N2 handover scenario, the source base station can provide multicast service information to the target base station through core network equipment. That is, the providing multicast service information to the target base station includes:

The multicast service information is provided to the target base station through a core network device.

In order to better understand the implementation of the present application, the following describes the handover process of the Xn handover scenario and the N2 handover scenario in detail.

Embodiment 1, in the Xn handover scenario, it is assumed that the source base station is a multicast base station. As shown in Figure 3, the handover process includes the following steps:

Step 301, the source base station decides to perform a handover operation, and after selecting a target base station, sends a handover request (handover request) message to the target base station.

Optionally, the source base station determines whether to carry multicast service information in the handover request message based on target information of the target base station, where the multicast service information may include a multicast service identifier and QoS requirement information related to the multicast service identifier.

Wherein, the target information of the target base station may be one or more of the following:

The base station type of the target base station, where the base station type includes non-multicast base stations and multicast base stations. The non-multicast base station refers to a base station that cannot provide multicast services through multicast. The multicast base station refers to a base station that can provide multicast services to a multicast base station. Exemplarily, if the target base station is a multicast base station, the source base station carries the multicast service information corresponding to the multicast service in the handover request message. If the target base station is a traditional base station, the source base station does not carry the multicast service information corresponding to the multicast service in the handover request message.

Service information supported by the target base station or service information not supported by the target base station. Exemplarily, if the source base station determines that the multicast service that the terminal is receiving at the source node or the multicast service that the terminal is interested in is a service that is not supported by the target base station, the source base station does not carry in the handover request message Multicast service information corresponding to the multicast service. If the source base station determines that the multicast service that the terminal is receiving at the source node or the multicast service that the terminal is interested in is the service supported by the target base station, the source base station carries the corresponding multicast service in the handover request message multicast service information.

The load status of the target base station, where the load status of the target base station includes the use status of the radio resources of the target base station, the number of users served by the target base station, and the like. Exemplarily, if the source base station determines that the radio resources of the target base station are not enough to reserve air interface resources for the multicast service received by the terminal at the source base station or the multicast service that the terminal is interested in, the source base station sends the request message in the handover request message. does not carry the multicast service information corresponding to the multicast service. If the source base station determines that the radio resources of the target base station are sufficient to reserve air interface resources for multicast services received by the terminal at the source base station or multicast services that the terminal is interested in, the source base station carries the handover request message with the Multicast service information corresponding to the multicast service.

It should be noted that, the target information of the target base station may be obtained by the source base station through interaction with the target base station before handover, such as through the Xn interface.

Step 302, the target base station receives the handover request message, and sends a handover response message (eg, handover response) to the source node.

Step 303, the source base station sends a handover command to the terminal.

Step 304, the terminal establishes a connection with the target base station, and after accessing the target base station, sends a handover confirmation message, such as a Handover Confirm message, to the target base station.

Embodiment 2, in an N2 handover scenario, it is assumed that the source base station is a multicast base station. As shown in Figure 4, the handover process includes the following steps:

Step 401, the source base station decides to perform the handover operation, and after selecting the target base station, sends a handover notification (Handover Required) message to the core network device.

Optionally, the source base station determines whether to carry multicast service information in the handover request message based on the target information of the target base station, where the multicast service information may include a multicast service identifier and QoS requirement information related to the multicast service identifier.

The base station type of the target base station, where the base station type includes non-multicast base stations and multicast base stations. The non-multicast base station refers to a base station that cannot provide multicast services through multicast. The multicast base station refers to a base station that can provide multicast services to a multicast base station. Exemplarily, if the target base station is a multicast base station, the source base station carries the multicast service information corresponding to the multicast service in the handover notification message. If the target base station is a traditional base station, the source base station does not carry the multicast service information corresponding to the multicast service in the handover notification message.

Service information supported by the target base station or service information not supported by the target base station. Exemplarily, if the source base station determines that the multicast service that the terminal is receiving at the source node or the multicast service that the terminal is interested in is a service not supported by the target base station, the source base station does not carry in the handover notification message Multicast service information corresponding to the multicast service. If the source base station determines that the multicast service that the terminal is receiving at the source node or the multicast service that the terminal is interested in is the service supported by the target base station, the source base station carries the corresponding multicast service in the handover notification message. multicast service information.

The load status of the target base station, where the load status of the target base station includes the use status of the radio resources of the target base station, the number of users served by the target base station, and the like. Exemplarily, if the source base station determines that the radio resources of the target base station are not enough to reserve air interface resources for the multicast service received by the terminal at the source base station or the multicast service that the terminal is interested in, the source base station sends the message in the handover notification message. does not carry the multicast service information corresponding to the multicast service. If the source base station determines that the radio resources of the target base station are sufficient to reserve air interface resources for multicast services received by the terminal at the source base station or multicast services that the terminal is interested in, the source base station carries the Multicast service information corresponding to the multicast service.

Step 402, the core network device (eg, a network function entity) sends a handover request message to the target base station, carrying the information in the handover notification message. For example, multicast service information may be included, and the multicast service information may include a multicast service identifier and QoS information related to the multicast service identifier. Exemplarily, if the handover notification message received by the core network device includes multicast service information, the core network device carries the multicast service information in the handover request message.

Step 403, the target base station returns a handover response, such as a Handover Response message, to the core network device.

Step 404, the core network device sends a handover command, such as a Handover Command message, to the source base station.

Step 405, the source base station sends a handover command to the user terminal UE.

Step 406, after the UE accesses the target base station, it sends a handover confirmation message, such as a Handover Confirm message, to the target base station.
