Description

Information processing method, switching control method, service network equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information processing method, a handover control method, a service network device, and a terminal.

Background

At present, an Automatic Neighbor optimization (ANR) function is proposed for a Neighbor, and the purpose is to realize Self-configuration (Self-optimization) and Self-operation (Self-operation) of the Neighbor. When the ANR function is started, the missing neighbor cell can be automatically discovered, and the missing neighbor cell is automatically added into the neighbor cell list, so that User Equipment (UE) can be smoothly switched to the target neighbor cell. The ANR can identify and delete mismatched, redundant neighbors. The neighbor self-adding function in the ANR function is as follows:

when the UE finds that the adjacent region in the system or the adjacent region in the different system is missed, the source evolution type base station (evolved Node B, eNB for short) firstly adds the information of the missed adjacent region to the adjacent region list.

However, a concept of a private Network (Non-Public Network, referred to as NPN for short) is proposed in 5G, and the NPN is further classified into different Network types in different development stages, for example, an independently deployed NPN or an Non-independently deployed NPN, and for such a newly-appeared Network type, using the existing ANR flow will cause an inaccurate neighbor list and affect the cell handover success rate of the terminal.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Currently, when a base station maintains a neighbor cell list, the following steps may be adopted:

a base station configures a cell with the strongest signal for UE measurement and reporting;

reporting a Physical Cell Identifier (PCI) of the strongest signal Cell by the UE;

if the base station does not find the PCI of the target cell in the neighbor cell list, requesting the UE to report a Global cell identifier (i.e. Global id);

the UE obtains global id by reading a Broadcast Control Channel (BCCH for short) of a target cell;

the UE reports the Global id information to the base station;

a Radio Resource Control (RRC) function module of the base station sends the received information to a neighbor cell detection function module for subsequent neighbor cell relationship management.

Fig. 1 is a schematic diagram of information flow when a base station maintains a neighbor cell list. As shown in fig. 1, the RRC module of the base station sends the received response information to the neighbor cell detection module, the neighbor cell detection module sends the neighbor cell addition information (i.e., NR addition information) to the neighbor cell list management module, and the neighbor cell list management module updates the neighbor cell list according to the neighbor cell update information (i.e., NR update information).

Referring to fig. 2, fig. 2 is a flowchart of an information processing method provided by an embodiment of the present invention, applied to a service network device, as shown in fig. 2, the method includes the following steps:

step 101, receiving a first report message sent by a terminal, where the first report message carries a PCI of a target cell, and the target cell is a strongest neighboring cell measured by the terminal or a neighboring cell whose signal strength exceeds a preset threshold.

Specifically, the serving network device configures a neighboring cell, where the UE (which may be understood as a terminal) measures and reports a strongest signal, and the terminal sends a first report message to the serving network device. The service network equipment receives a first report message sent by the terminal, wherein the first report message carries the PCI of the target cell. The target cell is the strongest neighboring cell measured by the terminal, which may be understood as the neighboring cell measured by the terminal with the strongest signal by the target cell.

And 102, under the condition that the PCI is not included in the neighbor cell list, determining whether to report or add the target cell to the neighbor cell list according to the network type of the service network device and the network type of the target cell, wherein the network types comprise a public network, an independently deployed private network and a non-independently deployed private network.

After obtaining the PCI of the target cell, the serving network device may query the neighbor cell list to determine whether the neighbor cell list includes the PCI of the target cell. If the PCI is not included in the neighbor list, the serving network device further determines whether to add the target cell to the neighbor list.

In determining whether to add the target cell to the neighbor list, the determination may be made according to the network type of the serving network device and the network type of the target cell. The network types of the service network device comprise a public network, an independently deployed private network and a non-independently deployed private network. The network types of the target cell comprise a public network, an independently deployed private network and a non-independently deployed private network.

In this embodiment, a first report message sent by a terminal is received, where the first report message carries a PCI of a target cell, and the target cell is a strongest neighboring cell measured by the terminal or a neighboring cell whose signal strength exceeds a preset threshold; and under the condition that the PCI is not included in the neighbor cell list, determining whether to report or add the target cell to the neighbor cell list according to the network type of the service network device and the network type of the target cell, wherein the network types comprise a public network, an independently deployed private network and a non-independently deployed private network. Therefore, when determining whether to add the target cell into the neighbor cell list, the target cell can be determined according to the network type of the service network equipment and the network type of the target cell, so that the service network equipment can more accurately maintain the neighbor cell list, and the success rate of switching the terminal cell is improved.

At present, after a target cell is found, a network type of a serving network device and a network type of the target cell are not distinguished, but the target cell is directly added into a neighbor cell list, after the target cell is added, some terminals cannot be switched to the cell, so that subsequent network devices initiate switching to the terminals, and when the target cell is used as a candidate cell for switching, the network type of the added target cell does not allow UE to be switched to the target cell, so that the problem of terminal switching failure is caused.

In the scheme of the specific embodiment of the present invention, because the network type of the serving network device and the network type of the target cell are considered before adding, it is possible to avoid adding a neighboring cell, which should not be added to the neighboring cell list, to the neighboring cell list.

For example, for an independently deployed private network, if a terminal accessing a public network cannot access the private network, the terminal reports to a base station after determining that a target cell is the independently deployed private network, and the base station should not add the target cell to a neighbor list.

For the non-independently deployed private network, if the terminal accessing the authorized private network can also use the public network, the base station should further update and maintain the neighbor cell list after acquiring the target cell as the non-independently deployed private network.

Further, determining whether to report or add the target cell to the neighbor cell list according to the network type of the serving network device and the network type of the target cell specifically includes at least one of the following steps:

the network type of the service network equipment is a public network, and the target cell is refused to be added to the neighbor cell list under the condition that the network type of the target cell is an independently deployed private network;

the network type of the service network equipment is a public network, and the target cell is added to the neighbor cell list under the condition that the network type of the target cell is a non-independently deployed private network;

the network type of the service network equipment is an independently deployed private network, and the target cell is refused to be added to the neighbor cell list under the condition that the network type of the target cell is a public network;

and the network type of the service network equipment is a non-independently deployed private network, and the target cell is added to the neighbor cell list under the condition that the network type of the target cell is a public network.

That is, in the case where the network type of the target cell or the serving network device is a non-independently deployed private network, the serving network device adds the target cell to the neighbor list. And under the condition that the network type of the target cell or the service network equipment is an independently deployed private network, the service network equipment refuses to add the target cell to the neighbor cell list.

If the PCI of the target cell is not included in the neighbor cell list, the serving network device further determines whether to add the target cell to the neighbor cell list, but whether to add the target cell is determined according to the network type of the serving network device and the network type of the target cell.

In the embodiment of the present invention, the network type of the target cell may be obtained by sending an indication message to the terminal. That is, after receiving the first report message sent by the terminal, the method further includes:

under the condition that the PCI is not included in the neighbor cell list, sending an indication message to indicate the terminal to report the cell information of the target cell;

and determining the network type of the target cell according to the response of the terminal to the indication message.

Specifically, when the neighbor cell list does not include the PCI of the target cell, the serving network device sends an indication message to the terminal, where the indication message is used to indicate the terminal to report cell information of the target cell. The serving network device may determine the network type of the target cell from the terminal's response to the indication message.

The response of the terminal to the indication message may include that the terminal sends a response message to the serving network device after receiving the indication message, or that the terminal does not send a response message to the serving network device after receiving the indication message. The serving network device may obtain the network type of the target cell according to the information carried in the received indication message, or the serving network device may obtain the network type of the target cell according to that no response message is received within a preset time.

Further, determining the network type of the target cell according to the response of the terminal to the indication message specifically includes:

determining that the network type of the target cell is an independently deployed private network under the condition that the response message is not received;

or

Determining the network type of the target cell according to the network type indication information of the target cell carried in the response message sent by the terminal;

or

Determining that the network type of the target cell is an independently deployed private network under the condition that a response message sent by the terminal does not include NPN identification information;

or

And under the condition that the response message sent by the terminal comprises NPN identification information, determining that the network type of the target cell is a non-independently deployed private network.

Specifically, if the network type of the target cell is an independently deployed private network, in this case, the serving network device will refuse to add the target cell to the neighbor list, so the terminal may not send a response message to the serving network device, and signaling overhead for sending the response message may be saved. The serving network device can know that the network type of the target cell is the independently deployed private network when not receiving the response message.

When the serving network device receives a response message sent by the terminal, the response message may carry network type indication information of the target cell, where the network type indication information includes at least one of the following information: the identity of the private network or explicitly indicated network type information.

The explicitly indicated network type information refers to information indicating a network type in an explicit manner. For example, when the network type information is 00, the network type of the target cell is a private network deployed independently; when the network type information is 01, the network type of the target cell is a non-independently deployed private network; when the network type information is 10, it indicates that the network type of the target cell is a public network. The serving network device may determine the network type of the target cell according to the network type indication information.

The identity of the private network may be understood as private network identity information, i.e. NPN identity information. If the network type indication information does not include NPN identification information, determining that the network type of the target cell is an independently deployed private network; and if the network type indication information comprises NPN identification information, determining that the network type of the target cell is a non-independently deployed private network.

Under the condition that service network equipment receives a response message sent by a terminal, if the response message does not include NPN identification information, determining that the network type of the target cell is an independently deployed private network; and if the response message comprises NPN identification information, determining that the network type of the target cell is a non-independently deployed private network.

Further, after determining whether to report or add the target cell to the neighbor cell list, the method further includes:

and recording the network type of the target cell under the condition that the network type of the target cell is a non-independently deployed private network and the target cell is added to the neighbor cell list. That is, when the target cell is added to the neighbor cell list, if the network type of the target cell is a private network that is not independently deployed, the service terminal device further records the network type of the target cell. Therefore, when the service terminal equipment initiates switching to the terminal and searches the adjacent cell list, the network type of the target cell can be obtained, and when the NPN subscription information of the terminal is consistent with the NPN attribute to which the target cell belongs, a switching request can be initiated to the target cell, so that the switching failure caused by the fact that the terminal is not authorized to access the NPN cell to which the target cell belongs is avoided.

When the network type of the serving network device is a public network and the network type of the target cell is a private network, and when the target cell is determined and whether the target cell is added to the neighbor cell list, the interaction process between the serving network device and the terminal is as follows:

a base station (which may be understood as serving network equipment) configures a cell for UE to measure and report (a Radio Access Technologies (RAT) or a frequency point) the strongest signal;

the UE reports the PCI of the detected strongest signal cell (namely the target cell);

the base station does not find the PCI in the neighbor cell list, and requests the UE to report the identification (i.e. Global id) of the Global cell;

the UE reads a BCCH of a target cell to obtain global id and NPN related information (e.g., NPN indication information, NPN identification information, etc.), where the NPN indication information may be a specially defined Public Land Mobile Network (PLMN) identifier (i.e., an independently deployed NPN Network identifier) or Closed Access Group (CAG) indication information (for indicating that an NPN Network is not independently deployed), and the NPN identifiers may be one or more (when the target cell belongs to multiple NPN, the NPN identifiers may be multiple);

the UE reports the Global id and the NPN related information to an RRC module of the base station through an RRC message;

the RRC module of the base station forwards the received information to a neighbor cell detection module of the base station, where the received information is used for updating and maintaining a neighbor cell list by the base station and an OAM (Operations, Administration, and Maintenance, OAM for short), where the base station determines a PLMN identifier of a target cell, and if the target cell is an independently deployed NPN network, the PLMN identifier may not be reported to the OAM, and if the target cell is an independently deployed NPN network, the OAM is reported for subsequently updating a neighbor cell relationship (and adding the target cell to the neighbor cell list).

When the network type of the serving network device is a public network and the network type of the target cell is a private network, and when the target cell is determined and whether the target cell is added to the neighbor cell list, the interaction process between the serving network device and the terminal may be:

the base station does not find the PCI in the neighbor cell list, requests the UE to report the target cell information, and reports an indication by the NPN: the NPN reporting indication is defined as that UE reads and judges whether a target cell is independently deployed with NPN or not;

the UE obtains global id and NPN related information (such as NPN indication information, NPN identification information and the like) by reading BCCH of the target cell and reports the information to the base station through RRC information; if the target cell is the independent deployment cell, the UE may not reply or reply to the target cell as the independent deployment cell, or reply according to the existing procedure (Global CID and PLMN information, without reporting NPN id); and if the target cell is a non-independent deployment cell, the UE reports the Global id and the NPN related information to the base station.

And the RRC module of the base station forwards the received information to the neighbor cell detection module of the base station, and the RRC module is used for updating and maintaining the neighbor cell list by the base station and the OAM.

When the base station updates and maintains the neighbor cell list, adding new attribute information in the neighbor cell list:

adding an NPN id or NPN id list to which a target cell belongs (only a non-independently deployed cell needs to be added to a neighbor list) in a Target Cell Identifier (TCI) attribute; when the UE accesses the network, the serving base station obtains NPN subscription information from a User Port Function (UPF) or an Access and Mobility Management Function (AMF);

when the base station initiates switching to the UE, the neighbor cell list is searched, NPN information of the candidate cell is checked and judged, and only when the NPN subscription information of the UE is consistent with the NPN attribute of the target cell, a switching request is initiated to the target cell, so that switching failure caused by the fact that the UE is not authorized to access the NPN cell to which the target cell belongs is avoided.

When the network type of the serving network device is a private network and the network type of the target cell is a public network, and when initiating an ANR procedure for a base station in an NPN network, if it is detected that the target cell reported by the UE belongs to the public network, a manner of determining whether to add the target cell to the neighbor list according to an NPN network attribute is as follows:

if the base station is an independently deployed private network and the target cell is a public network, the target cell is not added to the neighbor cell list without updating the neighbor cell list;

if the base station is a non-independently deployed private network and the target cell is a public network, the neighbor cell list can be updated, and the target cell is labeled in the neighbor cell list and labeled as a PN attribute; and when the user is only authorized to access the NPN network, the base station does not initiate a switching request to the PN cell according to the inquiry result of the neighbor cell list.

Referring to fig. 3, fig. 3 is another flowchart of an information processing method provided by an embodiment of the present invention, and is applied to a terminal, as shown in fig. 3, the method includes the following steps:

step 201, sending a first report message, where the first report message carries a PCI of a target cell, and the target cell is a strongest neighboring cell measured by the terminal or a neighboring cell whose signal strength exceeds a preset threshold.

Specifically, the serving network device configures a neighboring cell with the strongest measurement and report signal of the terminal, and the terminal sends a first report message to the serving network device, where the first report message carries the PCI of the target cell. The target cell is the strongest neighboring cell measured by the terminal, which may be understood as the neighboring cell measured by the terminal with the strongest signal by the target cell.

Step 202, receiving an indication message sent by the serving network device.

The serving network device may determine whether to add the target cell to the neighbor cell list according to a network type of the serving network device and a network type of the target cell. The serving network device may obtain the network type of the target cell by sending an indication message to the terminal. The indication message is used for indicating the terminal to report the cell information of the target cell.

Step 203, responding to the indication message, where the response is used for the serving network device to determine the network type of the target cell, and determine whether to add the target cell to the neighbor list in combination with the network type of the serving network device when the PCI is not included in the neighbor list, where the network types include a public network, an independently deployed private network, and an independently deployed private network.

Specifically, the response of the terminal to the indication message may include that the terminal sends a response message to the serving network device after receiving the indication message, or that the terminal does not send a response message to the serving network device after receiving the indication message, so as to inform the serving network device of the network type of the target cell. For example, the serving network device may obtain the network type of the target cell according to the information carried in the received indication message, or the serving network device may obtain the network type of the target cell according to that the response message is not received in a preset time, and so on.

In this embodiment, a first report message is sent, where the first report message carries a PCI of a target cell, and the target cell is a strongest neighboring cell measured by the terminal or a neighboring cell whose signal strength exceeds a preset threshold; receiving an indication message sent by a service network device; and responding to the indication message, wherein the response is used for determining the network type of the target cell by the serving network device, and determining whether to add the target cell to the neighbor cell list by combining the network type of the serving network device under the condition that the PCI is not included in the neighbor cell list, and the network types comprise a public network, an independently deployed private network and an independently deployed private network. Therefore, when the service network equipment determines whether to add the target cell into the neighbor cell list, the service network equipment can determine according to the network type of the service network equipment and the network type of the target cell, so that the service network equipment can more accurately maintain the neighbor cell list, and the success rate of switching the terminal cell is improved.

Further, the responding to the indication message specifically includes:

refusing to send a response message corresponding to the indication message under the condition that the network type of the target cell is an independently deployed private network;

or sending a response message corresponding to the indication message, wherein the response message carries the network type information of the target cell;

or sending a response message corresponding to the indication message, wherein the response message does not include NPN identification information under the condition that the network type of the target cell is an independently deployed private network;

or sending a response message corresponding to the indication message, wherein the response message comprises NPN identification information under the condition that the network type of the target cell is a non-independently deployed private network.

Specifically, if the network type of the target cell is an independently deployed private network, in this case, the serving network device will refuse to add the target cell to the neighbor list, so the terminal may not send a response message to the serving network device, and signaling overhead for sending the response message is saved. The serving network device can know that the network type of the target cell is the independently deployed private network when not receiving the response message.

In the case that the terminal sends a response message to the serving network device, the response message may carry network type indication information of the target cell, where the network type indication information includes at least one of the following information: the identity of the private network or explicitly indicated network type information.

Under the condition that the terminal sends a response message to the service network device, if the response message does not include NPN identification information, determining that the network type of the target cell is an independently deployed private network; and if the response message comprises NPN identification information, determining that the network type of the target cell is a non-independently deployed private network.

Referring to fig. 4, fig. 4 is a flowchart of a handover control method provided in an embodiment of the present invention, which is applied to a serving network device, and as shown in fig. 4, the method includes the following steps:
