In a New Radio (NR), it is expected to support continuity of multicast service data during cell handover, and the handover processing method of the present application is proposed for this purpose. Here, the cell handover may be understood as a mobile handover.
The following describes in detail a handover processing method provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 2, fig. 2 is a flowchart of a handover processing method provided in an embodiment of the present application, where the method is applied to a source base station, and as shown in fig. 2, the method includes the following steps:
wherein the target information comprises at least one of the following; base station type, supported traffic information, unsupported traffic information, and load information.
In this embodiment of the present application, the source base station may be understood as a current serving base station of a terminal, and the target base station refers to a target base station that performs a handover of the terminal in a handover process. For a cell handover procedure, a terminal may be handed over from a source cell to a target cell. The source base station may be understood as a network device in a source cell, and the target base station may be understood as a network device in a target cell.
The multicast service information may be understood as: the terminal receives the multicast service or the multicast service information corresponding to the multicast service which the terminal is interested in.
For example, in the case that a source base station decides a handover operation of a terminal during reception of a multicast service, the source base station may select a target base station, and may provide multicast service information for receiving the multicast service to the target base station based on target information of the target base station. Therefore, the terminal can be assisted to establish the multicast service connection after being switched to the target base station, and the continuity of the multicast service is realized.
The method for selecting the target base station by the source base station may be set according to actual needs, for example, in an embodiment, the method may be based on a measurement report reported by the terminal, may also be based on candidate cell information, and may also be selected autonomously.
It should be understood that the target information of the target base station may be obtained by the source base station before the handover is performed, for example, by interaction between the source base station and the target base station. Illustratively, the source base station and the target base station may interact through an Xn interface to obtain target information of the target base station.
In the embodiment of the application, the multicast service information is provided for the target base station based on the target information of the target base station, so that the terminal can be assisted to establish the multicast service connection after being switched to the target base station. Therefore, the embodiment of the application can realize the continuity of the multicast service.
It should be noted that the content included in the multicast service information may be set according to actual needs, for example, in an embodiment, the multicast service information includes a multicast service identifier. The multicast service identifier may be a Temporary Mobile Group Identity (TMGI) or a data flow Identity (QFI).
Optionally, in an embodiment, the multicast Service information may further include Quality of Service (QoS) requirement information corresponding to the multicast Service identifier.
Optionally, the base station types include a first type base station and a second type base station; the first base station is a base station which can provide multicast service in a multicast mode, and the second base station is a base station which cannot provide multicast service in the multicast mode.
In this embodiment, the first type of base station may be referred to as a multicast base station, and the second type of base station may be referred to as a conventional base station or a non-multicast base station. In the present embodiment, the source base station is understood as a multicast base station. The multicast mode can be understood as that the multicast service is provided by establishing a shared channel with a core network base station.
It should be understood that the above target information is used to determine whether to transmit the multicast service information to the target base station. For different target information, the conditions for sending the multicast service information are different. That is to say, in the embodiment of the present application, in the source base station, whether to provide the multicast service information to the target base station may be determined in different manners 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:
providing multicast service information to the target base station under the condition that the target information comprises a base station type and the base station type is a first-class base station, wherein the first-class base station is a base station capable of providing multicast service in a multicast mode;
providing multicast service information to the target base station under the condition that the target information comprises supported service information and a service corresponding to the supported service information comprises a target service;
under the condition that the target information comprises unsupported service information and the service corresponding to the unsupported service information does not contain the target service, providing multicast service information for the target base station;
providing multicast service information to a target base station under the condition that the target information comprises load information and the wireless resource of the target base station is determined to be enough to reserve air interface resources for target service based on the load information;
the target service is a multicast service which is being received by a terminal or a multicast service which is interested by the terminal.
The load information may be understood as a load condition of the target terminal, and may include, for example, a usage condition of radio resources of the target base station, the number of users served by the target base station, and the like.
Aiming at the base station type, if the target base station is a multicast base station, the source base station provides multicast service information for the target base station; and if the target base station is the traditional base station, the source base station does not provide the multicast service information to the target base station. That is, when the target information includes the base station type, the source base station provides the multicast service information to the target base station with the condition one: 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, whether the target multicast service being received by the terminal or the target multicast service interested by the terminal is a multicast service supported by the target base station. If the target multicast service is the multicast service supported by the target base station, the source base station provides multicast service information to the target base station; and if the target multicast service is the multicast service which is not supported by the target base station, the source base station does not provide the multicast service information for the target base station. That is, when the target information includes at least one of supported service information and unsupported service information, the source base station needs to satisfy the condition two for providing the multicast service information to the target base station: the target multicast service which is being received by the terminal or the target multicast service which is interested by the terminal is the multicast service supported by the target base station.
As an example, the multicast services being received by the terminal include multicast service 1 and multicast service 2, where the multicast service 1 is supported by the target base station, and the multicast service 2 is not supported by the target base station, and 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 load information, the source base station may 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 interested by the terminal. If the wireless resources of the target base station are determined to be insufficient to reserve air interface resources for the target multicast service, multicast service information is not provided for the target base station; and if the wireless resources of the target base station are determined to be enough to reserve air interface resources for the target multicast service, providing the multicast service information for the target base station. That is, when the target information includes the load information, the source base station needs to satisfy the condition three for providing the multicast service information to the target base station: the wireless resource of the target base station is enough to reserve air interface resources for the target multicast service which is being received by the terminal or the target multicast service which is interested by the terminal.
As an example, the multicast service being received by the terminal includes multicast service 1 and multicast service 2, and the radio resource of the target base station can only reserve an air interface resource for one multicast service, so that the terminal only provides the multicast service information corresponding to one multicast service, for example, provides the multicast service information corresponding to multicast service 1. The source base station may arbitrarily select which multicast service information of the multicast service or the multicast service information of the multicast service is provided to the target base station, that is, the source base station may provide the multicast service information corresponding to the multicast service 1 to the target base station, and may also provide the multicast service information corresponding to the multicast service 2 to the target base station, where the specific behavior depends on the implementation of the base station. As another example, the source base station may determine which multicast service information is provided to the target base station according to the QoS information corresponding to the multicast service, for example, if the delay requirement corresponding to the multicast service 1 is smaller than the delay requirement of the multicast service 2, the source base station provides the multicast service information corresponding to the multicast service with a smaller delay requirement to the target base station.
It should be noted that the handover of the terminal may include an Xn handover scenario and an N2 handover scenario, and for different handover scenarios, the corresponding source base station provides the multicast service information to the target base station in different manners.
For an Xn handover scenario, the source base station may directly provide multicast service information to the target base station.
For the N2 handover scenario, the source base station may provide multicast service information to the target base station through the core network device. That is, the providing the multicast service information to the target base station includes:
and providing the multicast service information to the target base station through core network equipment.
For better understanding of the implementation of the present application, the following description is made in detail with respect to the switching process of the Xn switching scenario and the N2 switching scenario.
In the first embodiment, Xn switches the scenario, assuming that the source base station is a multicast base station. As shown in fig. 3, the handover procedure includes the following steps:
step 301, the source base station determines to execute a handover operation, and after selecting a target base station, sends a handover request message to the target base station.
Optionally, the source base station determines whether the handover request message carries multicast service information 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:
and the base station types of the target base station comprise a non-multicast base station and a multicast base station. The non-multicast base station refers to a base station which cannot provide multicast service in a multicast mode. The multicast base station refers to a base station which can provide multicast service through a multicast mode. Illustratively, if the target base station is a multicast base station, the source base station carries multicast service information corresponding to the multicast service in the handover request message. And 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 switching request message.
Service information supported by the target base station or service information not supported by the target base station. Illustratively, if the source base station determines that the multicast service being received by the terminal at the source node or the multicast service interested by the terminal is a service that is not supported by the target base station, the source base station does not carry multicast service information corresponding to the multicast service in the handover request message. And if the source base station determines that the multicast service which is received by the terminal at the source node or the multicast service which is interested by the terminal is the service supported by the target base station, the source base station carries the multicast service information corresponding to the multicast service in the switching request message.
The load condition of the target base station comprises the use condition of the wireless resources of the target base station, the number of users served by the target base station and the like. For example, if the source base station determines that the radio resource of the target base station is not sufficient to reserve an air interface resource for the multicast service received by the terminal at the source base station or the multicast service interested by the terminal, the source base station does not carry the multicast service information corresponding to the multicast service in the handover request message. If the source base station determines that the wireless resource of the target base station is sufficient to reserve an air interface resource for the multicast service received by the terminal at the source base station or the multicast service interested by the terminal, the source base station carries the multicast service information corresponding to the multicast service in the switching request message.
It should be noted that the target information of the target base station may be obtained by the source base station interacting with the target base station before handover, for example, through an Xn interface.
Step 302, the target base station receives the handover request message and sends a handover response message (such as 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 sends a Handover confirmation message, such as a Handover Confirm message, to the target base station after accessing the target base station.
Embodiment two, N2 switches scenarios, assuming the source base station is a multicast base station. As shown in fig. 4, the handover procedure includes the following steps:
step 401, the source base station determines to execute a Handover operation, and after selecting the target base station, sends a Handover Required message to the core network device.
Optionally, the source base station determines whether the handover request message carries multicast service information 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:
and the base station types of the target base station comprise a non-multicast base station and a multicast base station. The non-multicast base station refers to a base station which cannot provide multicast service in a multicast mode. The multicast base station refers to a base station which can provide multicast service through a multicast mode. Illustratively, if the target base station is a multicast base station, the source base station carries multicast service information corresponding to the multicast service in the handover notification message. And 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 switching notification message.
Service information supported by the target base station or service information not supported by the target base station. For example, if the source base station determines that the multicast service being received by the terminal at the source node or the multicast service interested by the terminal is a service that is not supported by the target base station, the source base station does not carry the multicast service information corresponding to the multicast service in the handover notification message. And if the source base station determines that the multicast service which is received by the terminal at the source node or the multicast service which is interested by the terminal is the service supported by the target base station, the source base station carries the multicast service information corresponding to the multicast service in the switching notification message.
The load condition of the target base station comprises the use condition of the wireless resources of the target base station, the number of users served by the target base station and the like. For example, if the source base station determines that the radio resource of the target base station is not sufficient to reserve an air interface resource for the multicast service received by the terminal at the source base station or the multicast service interested by the terminal, the source base station does not carry the multicast service information corresponding to the multicast service in the handover notification message. If the source base station determines that the wireless resource of the target base station is sufficient to reserve an air interface resource for the multicast service received by the terminal at the source base station or the multicast service interested by the terminal, the source base station carries the multicast service information corresponding to the multicast service in the switching notification message.
Step 402, a core network device (e.g. a network function entity) sends a handover request message to a target base station, where the handover request message carries information in a handover notification message. For example, multicast service information may be included, which may include QoS information that a multicast service identification is associated with a multicast service identification. Illustratively, if the handover notification message received by the core network device includes multicast service information, the multicast service information is carried in the handover request message at the core network device.
In step 403, the target base station returns a Handover Response, such as a Handover Response message, to the core network device.
In 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 equipment UE.
In step 406, after accessing the target base station, the UE sends a Handover confirmation message, such as a Handover Confirm message, to the target base station.
In the handover processing method provided in the embodiment of the present application, the execution main body may be a handover processing apparatus, or a control module in the handover processing apparatus for executing the handover processing method. In the embodiment of the present application, a switching processing device executing a switching processing method is taken as an example to describe the switching processing device provided in the embodiment of the present application.
