Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The terms first, second and the like in the description and in the claims of the application and in the above-described figures, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. In addition, in the description with reference to the drawings, the same reference numerals in different drawings denote the same elements.
The following describes specific embodiments of the present application in detail with reference to the drawings.
Fig. 1 is a flowchart of a method for network handover, according to an exemplary embodiment, applied to a User Equipment (UE), as shown in fig. 1, the method may include the steps of:
In step S101, if it is determined that the target network belongs to the shared network, the first link information of the service network is acquired under the condition that a network switching instruction issued by the first network device of the currently connected service network is received.
In an actual scenario, a service network connected to the user equipment configures network information of a neighboring cell, and the user equipment continuously detects a current network condition and reports the current network condition to a first network device of the service network. In this way, the first network device can analyze and obtain whether the user device needs to switch networks currently according to the detection result sent by the user device and the network information of the neighbor cells. And issuing a network switching instruction to the user equipment under the condition that switching is required. The network switching instruction is used for indicating the user equipment to switch from the service network to the target network.
In addition, in the related art, if the target network to be switched by the ue is a network shared by multiple operators. After the network registration is successful, a link path registration request needs to be initiated to the target network, and a new link path is reestablished. The whole process lasts for 5-10 seconds, during which voice service and data service cannot be performed, and the experience of the user is poor.
Therefore, in order to solve the above-mentioned problem, in this embodiment, when a network switching instruction issued by a first network device of a currently connected service network is received, if it is determined that a target network belongs to a shared network, first link information of the service network is acquired. The first link information is used for representing a data link which is established between the current user equipment and the service network and is in a keep-alive state. The first link information includes at least network slice information (NSSAI information), protocol data unit session (PDU (English: protocol Data Unit; chinese: protocol data unit)) and uplink data status flag information (uplink data status). The network slice information is used for configuration of Network Slice Selection Auxiliary Information (NSSAI) of the user equipment, the protocol data unit session is used for indicating point-to-point link context information established by the data packet interaction service of the user equipment and the first network equipment, and the uplink data state information is used for indicating a state flag bit of uplink data in a link established with the service network.
That is, in the case where it is determined that the target network belongs to the shared network, first link information of the current service network is first saved so that the first link information is then migrated into the target network.
In step S102, a registration request message is sent to a second network device of the target network according to the first link information, where the registration request message includes the first link information, and the registration request message is used to instruct the second network device to migrate the first link information into the target network.
Wherein the registration request message is further used to request registration of the user equipment to the target network.
In this step, the first link information is added to the registration request message to be sent, so that the registration request message to be sent carries the first link information. In this way, after the registration request message added with the first link information is sent to the second network device, the second network device can migrate the first link information into the target network.
By adopting the method, under the condition that the target network to be switched is a shared network, the first link information of the service network is acquired, and the registration request message containing the first link information is sent to the second network equipment of the target network, so that the second network equipment transfers the first link information to the target network. In this way, in the process of switching between networks, the first link information of the service network is reserved, so that the voice path and the data path are ensured to be uninterrupted. And after switching to the target network, the link connection request does not need to be initiated to the target network again, so that the user does not have switching perception, and the user experience is improved.
Fig. 2 is a flowchart of another method for network handover according to an exemplary embodiment, and as shown in fig. 2, the step S102 of sending a registration request message to the second network device of the target network according to the first link information includes the following steps:
in step S1021, the first link information is added to a registration request message to be transmitted.
Specifically, a target information element field (IE field) may be first generated from the first link information. For example, in case the first link information includes network slice information, protocol data unit session, and uplink data status flag information, the generated target information element fields are as follows:
sl_ue_mwk_cap_incl＝0(0×0)
uplink_data_status_incl＝0(0×0)
pdu_session_status_incl＝0(0×0)
the target information element field is then added to the registration request message to be sent. For example, the target information element field may be configured into a registration request message to be sent.
In step S1022, a registration request message to which the first link information is added is transmitted to the second network device.
Fig. 3 is a flowchart of another method for network handover according to an exemplary embodiment, as shown in fig. 3, in the case of receiving a network handover instruction issued by a first network device of a currently connected service network in step S101, if it is determined that the target network belongs to the shared network, the step of obtaining first link information of the service network includes the following steps:
In step S1011, when a network handover instruction issued by the first network device is received, cell access related information (cellaccessrelateinfo) of a target cell corresponding to the target network is acquired.
The cell access related information may be obtained from SIB (System Information Block) information of the target cell.
In step S1012, it is determined whether the target network belongs to the shared network according to the cell access related information.
In some embodiments, first, the first public land mobile network PLMN (english: public Land Mobile Network) identifier list may be parsed from the cell access related information according to a target protocol parsing algorithm. The first PLMN identification list may be obtained by parsing the cell access related information through a protocol parsing algorithm in the related technology, which is not described herein.
Since the PLMN identities of the shared network are all fixedly set by the operators, the PLMN identities are not dynamically updated. Thus, in this embodiment, the second PLMN identification list of the shared network may be obtained. And further determining whether the target network belongs to the shared network according to the first PLMN identification list and the second PLMN identification list.
Further, in case the first identification information in the first PLMN identification list includes the second identification information in the second PLMN identification list, it may be determined that the target network belongs to the shared network. In the case that the first identification information in the first PLMN identification list does not include the second identification information in the second PLMN identification list, it may be determined that the target network does not belong to the shared network, that is, it may be determined that the target network and the service network belong to the same operator, and network handover may be performed by a method of inter-network handover of the same operator in the related art.
The second identification information may include, for example, 46031, 46051, 46021, or the like. That is, if the first identification information includes the second identification information, it may be determined that the target network belongs to the shared network.
It should be noted that the above examples are merely illustrative, and the present disclosure is not limited thereto.
In step S1013, in the case where it is determined that the target network belongs to the shared network, the first link information of the currently connected network is acquired.
By adopting the method, under the condition that the target network to be switched is a shared network, the first link information of the service network is acquired, and the registration request message containing the first link information is sent to the second network equipment of the target network, so that the second network equipment transfers the first link information to the target network. In this way, in the process of switching between networks, the first link information of the service network is reserved, so that the voice path and the data path are ensured to be uninterrupted. And after switching to the target network, the link connection request does not need to be initiated to the target network again, so that the user does not have switching perception, and the user experience is improved.
Fig. 4 is a flowchart illustrating a method of network switching, according to an exemplary embodiment, for use with a second network device, as shown in fig. 4, the method may include the steps of:
in step S201, in the case of receiving the registration request message sent by the user equipment, it is determined whether the registration request message includes first link information of the serving network.
The first link information is link information between the service network and the user equipment, and the registration request message is used for requesting the user equipment to be registered in the target network.
In step S202, when the first link information is included in the registration request message, the first link information is migrated to the target network.
Wherein when the registration request message is determined to include the first link information of the serving network, the registration request message is further used to instruct the second network device to migrate the first link information into the target network.
After the first link information is successfully migrated to the target network, as shown in fig. 5, the method further includes:
in step S203, in the case that the first link information is successfully migrated to the target network, second link information of the target network is acquired.
The second link information is used for representing a data link which is established between the current user equipment and the target network and is in a keep-alive state.
In step S204, the second link information is sent to the user equipment.
Therefore, after re-registering to the target network, the user equipment does not need to re-establish a data link with the target network, namely, the voice path and the data path do not need to be re-established, thereby reducing the condition of missed call or data interruption of the user and greatly improving the user experience.
By adopting the method, the second network equipment determines whether the registration request message contains the first link information of the service network or not under the condition that the second network equipment receives the registration request message sent by the user equipment; and migrating the first link information to the target network under the condition that the first link information is contained in the registration request message. In this way, the user equipment reserves the first link information of the service network in the process of switching between networks, thereby ensuring that the voice path and the data path are not interrupted. And after switching to the target network, the link connection request does not need to be initiated to the target network again, so that the user does not have switching perception, and the user experience is improved.
Fig. 6 is a flow chart illustrating a method of network handover, as shown in fig. 6, according to an exemplary embodiment, the method may include the steps of:
in step S301, the ue obtains information related to cell access of a target cell corresponding to a target network when receiving a network handover instruction issued by a first network device of a currently connected service network.
In step S302, the ue determines whether the target network belongs to the shared network according to the cell access related information.
In step S303, the user equipment obtains the first link information of the currently connected network in case that it is determined that the target network belongs to the shared network.
In step S304, the user equipment adds the first link information to a registration request message to be transmitted.
For example, a target information element field may first be generated from the first link information. The target information element field is then added to the registration request message to be sent.
In step S305, the user equipment transmits a registration request message to which the first link information is added to the second network equipment.
In step S306, the second network device determines, when receiving the registration request message sent by the user device, whether the registration request message includes first link information of the serving network.
In step S307, the second network device migrates the first link information to the target network in the case where the first link information is included in the registration request message.
In step S308, the second network device obtains the second link information of the target network if the first link information is successfully migrated to the target network.
In step S309, the second network device sends the second link information to the user device.
It should be noted that, regarding the method in the above embodiment, the specific manner in which the operations are performed by the steps has been described in detail in the embodiment of fig. 1 to 5, and will not be described in detail herein.
By adopting the method, under the condition that the target network to be switched is a shared network, the first link information of the service network is acquired, and the registration request message containing the first link information is sent to the second network equipment of the target network, so that the second network equipment transfers the first link information to the target network. In this way, in the process of switching between networks, the first link information of the service network is reserved, so that the voice path and the data path are ensured to be uninterrupted. And after switching to the target network, the link connection request does not need to be initiated to the target network again, so that the user does not have switching perception, and the user experience is improved.
