Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
The following "first", "second", etc. are used merely to describe differences and are not otherwise specifically meant.
In an idle state, the terminal may leave the current serving cell for some reasons, camp on a neighboring cell, and the process is cell reselection. Fig. 1 is a flow diagram of one embodiment of a cell reselection method for a shared network according to the present disclosure, as shown in fig. 1:
step 101, acquiring configuration information of a neighboring cell corresponding to the public land mobile network PLMN (Public Land Mobile Network) ID in the shared network, and acquiring first priority information of the neighboring cell based on the configuration information of the neighboring cell.
In one embodiment, the shared network comprises a shared network composed of 5G SA networks of multiple operators, and the shared network is composed based on a multi-operator core network MOCN sharing manner. The 5G shared network supports MOCN (Multi-Operator Core Network, MOCN) mode, i.e. core network independent, access network sharing, and the architecture diagram of the shared network is shown in fig. 2.
The 5G New air interface (NR) networking defines two schemes, namely independent networking (SA) and Non-independent Networking (NSA). Operators can be China telecom, china Unicom and the like, operators of the shared network can respectively adopt different deployment schemes, for example, both sharing parties can adopt SA networking to form an SA+SA sharing scene; or one party adopts SA networking, and the other party adopts NSA networking to form SA+NSA sharing scenes.
Step 102, determining candidate neighbor cells based on a preset measurement strategy and according to the first priority information.
And 103, carrying out measurement processing on the candidate neighbor cells to acquire signal quality information corresponding to the candidate neighbor cells. After determining the candidate neighbor cells, the signal quality information corresponding to the candidate neighbor cells may be acquired using existing measurement methods.
Step 104, obtaining the second priority information of the cell working frequency point corresponding to the PLMN ID.
Step 105, cell reselection processing is performed based on a preset cell reselection strategy and according to the signal quality information and the second priority information.
Various methods may be used to obtain the first priority information of the neighboring cell. Fig. 3 is a flowchart of acquiring first priority information of a neighboring cell in an embodiment of a cell reselection method for a shared network according to the present disclosure, as shown in fig. 3:
step 301, acquiring a system message sent by a serving cell, and acquiring a PLMN ID and neighbor cell configuration information from the system message; the neighbor cell configuration information comprises neighbor cell identifiers and neighbor cell priorities corresponding to PLMN IDs.
In one embodiment, the terminal receives a system message, such as SIB (System Information Block), sent by a serving cell (resident cell), and obtains a PLMN ID and neighbor cell configuration information from the system message, where the neighbor cell configuration information includes a neighbor cell identifier and a neighbor cell priority corresponding to the PLMN ID. The neighbor cell configuration information may use a variety of specific formats.
Step 302, acquiring a neighbor cell identifier and corresponding first priority information based on neighbor cell configuration information.
In one embodiment, the terminal extracts the PLMN ID and corresponding neighbor cell configuration information from the system message, extracts the neighbor cell identifier and the neighbor cell priority from the neighbor cell configuration information, and the neighbor cell priority is the first priority information.
A variety of measurement strategies may be provided. For example, third priority information corresponding to the current service cell is acquired, and a neighbor cell with higher priority than the current service cell is selected as a candidate neighbor cell according to the first priority information and the third priority information. The terminal can receive the system message sent by the current service cell (resident cell), and extract the third priority information corresponding to the current service cell from the system message; the terminal presets a measurement strategy, and selects a neighbor cell with higher priority than the current service cell as a candidate neighbor cell according to the measurement strategy.
The terminal is able to perform cell reselection based on the PLMN ID. The terminal acquires a system message sent by a resident cell, acquires a neighbor cell with higher priority than a current service cell from the system message, and executes measurement processing on the neighbor cell with high priority. The network side sets the priorities of the exclusive cell and the shared cell, and can comprehensively set the priority information of the cells according to factors such as a load threshold, a charging policy and the like.
The terminal may also measure according to existing rules. For example, for the same frequency/same priority cell, if the serving cell is less than or equal to the same frequency measurement start threshold, the terminal performs measurement, otherwise, does not perform measurement; when the system message indicates that the priority is lower than the service cell, if the S value of the service cell is smaller than or equal to the inter-frequency/inter-system measurement starting threshold, the terminal performs measurement, otherwise, does not perform measurement.
In one embodiment, there may be a plurality of types of second priority information for acquiring the cell operating frequency point corresponding to the PLMN ID. For example, a broadcast message or an RRC connection release message is received, and second priority information of the cell operating frequency point corresponding to the PLMN ID is acquired from the broadcast message or the RRC connection release message.
The broadcast message comprises SIB message and the like, and the information carried in the SIB message comprises a plurality of PLMN IDs and cell selection information corresponding to each PLMN ID; the cell selection information comprises a cell working frequency point, corresponding second priority information and the like. The information carried in the SIB message also includes parameters indicating support for the shared scene, etc.
The terminal acquires the priority information (public priority) of the frequency point through a resident cell broadcast message or acquires the priority information (private priority) of the frequency point through an RRC connection release message. The broadcast message and the RRC connection release message support frequency point priority information for distinguishing PLMNs.
In the sa+sa sharing scenario, the system message may be SIB1, SIB2, SIB4, etc., where the same-frequency and different-frequency reselection parameters are configured in SIB2, SIB4, including all shared and non-shared neighbor cells. The broadcast information includes a PLMN ID set of a plurality of operators to which the broadcast information is connected, and cell identifiers, access control information and the like under each PLMN, so as to support configuration of frequency point information and priority information respectively corresponding to the co-established parties. PLMN ID information may be added to the cell selection information of SIB1, and examples of the asn.1 code of SIB1 after adding the PLMN ID information are as follows:
wherein, the PLMN-IdentityIndex parameter value is PLMN ID, cellSelectionInfo-perPlmn parameter value is the cell selection information corresponding to each PLMN ID; the cell selection information comprises a cell working frequency point, corresponding second priority information and the like; multiOpSharing-Support is a parameter indicating Support for shared scenarios.
In one embodiment, there may be multiple cell reselection strategies. Fig. 4 is a flow chart illustrating a cell reselection process in one embodiment of a cell reselection method for a shared network according to the present disclosure, as shown in fig. 4:
step 401, acquiring a plurality of signal quality information corresponding to a plurality of candidate neighbor cells.
Step 402, determining second priority information corresponding to each signal quality information based on the PLMN ID.

The terminal A acquires first priority information respectively associated with the adjacent cell 1, the adjacent cell 2, the adjacent cell 3 and the adjacent cell 4 from the system message.

Based on the cell reselection strategy, scoring function F is used and scoring information corresponding to each candidate neighbor cell is determined according to each signal quality information and corresponding second priority information. The scoring function F may be various, the score of the neighboring cell 1 is calculated as F (Q1, R11), the score of the neighboring cell 3 is calculated as F (Q3, R32), and if F (Q1, R11) is greater than F (Q3, R32), the neighboring cell 1 is selected as the target neighboring cell for performing the cell reselection process.
