Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a terminal network selection method, apparatus, and equipment. Background Technology

[0002] The existing connection-mode load balancing can only be implemented when the terminal is connected. After a short period of time, the terminal will still return to the original network and initiate services on the original network once the conditions are met.

[0003] The existing load balancer in the IDLE state defines different dedicated frequency priority in RRCrelease (Radio Link Control Release). However, after a period of time or after the terminal switches or drops out, the priority of this dedicated frequency becomes invalid, and the terminal reverts to the original public frequency priority. The dedicated frequency priority has a limited duration of effect.

[0004] In co-site coverage scenarios, such as those with similar frequency bands (e.g., 1800MHz and 1900MHz), the inability to distinguish user location for terminal network selection results in poor performance for both fixed frequency priority and frequent connection-state load balancing. In high-speed rail scenarios, where high-frequency and low-frequency bands are completely co-located, real-time load balancing can cause terminals to constantly switch between frequencies at high speeds, leading to dropped connections.

[0005] Existing dedicated frequency priority load balancing solutions become ineffective after site switching, leading to frequent terminal switching in high-speed environments and causing network load imbalance. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a terminal network selection method, apparatus and equipment to ensure that the terminal can use dedicated frequency point priority network selection even after a long period of time or after switching, to achieve differentiated network selection in the idle state, and to achieve load balancing when accessing the network.

[0017] When a terminal disconnects, the terminal information report includes the priority of the preceding dedicated frequency point. The network device then uses this priority to identify the preceding dedicated frequency point as the identifier carried in the Radio Link Control Release (RRCrelease) message.

[0018] When a terminal switches to a target network, the network devices in the target network configure a prior dedicated frequency priority identifier or a dedicated frequency priority identifier that is the same as the prior priority for the terminal.

[0019] Optionally, the network device marks a dedicated frequency point priority identifier for the terminal based on the terminal's access frequency point or network load, including:

[0020] The network device compares the priority order of the terminal's access frequency point and dedicated frequency point, and blindly determines the priority identifier of the terminal's preceding dedicated frequency point as the terminal's dedicated frequency point priority identifier.

[0041] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0042] like Figure 1 As shown, an embodiment of the present invention provides a terminal network selection method, applied to a terminal, the method comprising:

[0043] Step 11: Receive target signaling sent by the network device. The target signaling is sent by the network device when it determines that the terminal is in an idle state and a high-speed state. The target signaling carries a priority identifier of a dedicated frequency point that is continuously valid for a preset time for the terminal.

[0044] Step 12: When the terminal accesses the target network, the target network is selected according to the priority of the dedicated frequency point corresponding to the priority identifier of the terminal's dedicated frequency point, and the terminal accesses the target network.

[0045] Here, the target signaling includes, but is not limited to: Radio Link Control (RRC) signaling, specifically RRC release signaling; it can also be signaling related to sending system messages. Different dedicated frequency point priority identifiers correspond to different dedicated frequency point priority orders, and the dedicated frequency point priority identifiers can be indices corresponding to the priority order of different frequency points.

[0046] In this embodiment of the present invention, the terminal receives target signaling sent by the network device. The target signaling carries a dedicated frequency priority identifier that is continuously valid for a preset time for the terminal. The terminal selects a target network according to the dedicated frequency priority corresponding to the dedicated frequency priority identifier and accesses the target network. This ensures that the terminal can use dedicated frequency priority to select a network even after a long period of time or after switching, and achieves differentiated network selection in the idle state, thereby achieving load balancing when accessing the network.

[0047] In an optional embodiment of the present invention, the dedicated frequency priority identifier mentioned in step 11 is marked by the core network and obtained by the network device (e.g., base station) from the core network, or the dedicated frequency priority identifier is marked by the network device.

[0048] Wherein, the dedicated frequency point priority identifier is marked by the core network, and when the network device obtains the dedicated frequency point priority identifier from the core network, the terminal network selection method further includes:

[0049] If the network device updates the dedicated frequency priority identifier, it interacts with the core network through the Frequency Selection Priority Function (RFSP) of the preset interface to synchronize the updated dedicated frequency priority identifier to the core network.

[0050] In this embodiment, the core network stores dedicated frequency point priority identifiers. In the 5G NR system, RFSP (RAT / Frequency Selection Priority) is used to mark whether a terminal is a high-speed terminal or a low-speed terminal. RFSP uses 256 indices to represent the QoS (voice / data) supported by the terminal. The base station then determines the dedicated frequency point priority of the terminal based on the RFSP. Here, the core network adds a secondary RFSP type indicator to represent the dedicated frequency point priority identifier. When the base station determines the dedicated frequency point priority of the terminal based on the RFSP, it allocates different dedicated frequency point priorities to different high-speed users. For example, some high-speed users are given priority in high-frequency bands, while some users are given priority in low-frequency bands.

[0051] When the base station obtains the dedicated frequency priority identifier from the core network, the base station interacts with the core network, and the core network saves the primary speed identifier and the secondary identifier of the dedicated frequency priority identifier.

[0052] In some cases, when the dedicated frequency priority identifier of a terminal is updated, the base station can update the dedicated frequency priority identifier and interact with the core network through the RFSP of the NG interface to exchange the updated dedicated frequency priority identifier, so that when the terminal subsequently accesses the target network (e.g., the target cell), it can use the updated dedicated frequency priority identifier for access.

[0053] The information stored by the terminal in the core network includes the terminal's high / low speed identifier and the newly added dedicated frequency priority identifier. Thus, during terminal access and handover, the base station obtains the terminal's dedicated frequency priority identifier from the core network. During the RRCrelease process, different dedicated frequency priorities are configured for each user according to the dedicated frequency priority identifier. The dedicated frequency priority identifier remains unchanged when the terminal is on the network, and load balancing is achieved in the IDLE (idle) state.

[0054] In this embodiment, the core network stores the priority identifier of the dedicated frequency point, so that the priority identifier of the dedicated frequency point will not become invalid due to the terminal's disconnection or switching. The priority identifier of the dedicated frequency point is relatively fixed and will not change for a long time, thereby enabling the terminal to access the target network quickly and stably.

[0055] In another optional embodiment of the present invention, when the dedicated frequency point priority identifier mentioned in step 11 is marked by the network device, it may include:

[0056] The terminal reports the priority identifier of its preceding dedicated frequency point. The network device then marks the terminal with a dedicated frequency point priority identifier based on the preceding dedicated frequency point priority identifier, or the network device marks the terminal with a dedicated frequency point priority identifier based on the terminal's access frequency point or network load, or the network device marks the terminal with a dedicated frequency point priority identifier based on a preset rule; wherein, the preceding dedicated frequency point priority identifier is the priority identifier of the last dedicated frequency point used by the terminal before accessing the target network.

[0057] The terminal reports the priority identifier of its preceding dedicated frequency point, and the network device marks the dedicated frequency point priority identifier of the terminal according to the priority identifier of the preceding dedicated frequency point.

[0058] The specific implementation process of the prior dedicated frequency priority identifier being the priority identifier of the last dedicated frequency used by the terminal before accessing the target network includes:

[0059] The terminal reports its own preceding dedicated frequency priority identifier. The base station carries the dedicated frequency priority identifier and the corresponding dedicated frequency priority order in the RRC reconfiguration. The terminal receives and saves the dedicated frequency priority identifier.

[0060] For example, when a terminal drops the connection, the priority of the preceding dedicated frequency point is carried in the terminal information report. The network device identifies the preceding dedicated frequency point priority in the Radio Link Control Release (RRCrelease) based on the priority of the preceding dedicated frequency point; or

[0061] When a terminal switches to a target network, the network devices in the target network configure a prior dedicated frequency priority identifier or a dedicated frequency priority identifier that is the same as the prior priority for the terminal.

[0062] In this embodiment, when the terminal drops the connection, after the terminal reselects the access system PRACH (Physical Random Access Channel) process, the last dedicated frequency point priority identifier information is included in the UE information (terminal information) report. The network device includes the previous dedicated frequency point priority in the RRCrelwase according to the dedicated frequency point priority information.

[0063] When a terminal switches to a target network, the network devices exchange dedicated frequency priority identifiers and corresponding frequency priority order tables on the Xn (interface between two network devices) interface. After the switch is completed, the network devices in the target network configure a previous dedicated frequency priority identifier or a dedicated frequency priority identifier with the same previous priority for the terminal. The previous dedicated frequency priority identifier is the dedicated frequency priority identifier last used by the terminal before accessing the target network. This allows the terminal to access the network through the corresponding dedicated frequency priority when it drops the connection or switches to the target network, thereby achieving network load balancing.

[0064] In another optional embodiment of the present invention, the network device marks the terminal with a dedicated frequency priority identifier according to the terminal's access frequency or network load, including: the network device blindly judges the terminal's preceding dedicated frequency priority identifier as the terminal's dedicated frequency priority identifier by comparing the priority order of the terminal's access frequency and dedicated frequency.

[0065] In this embodiment, the network device determines the priority identifier of the terminal's preceding dedicated frequency. Some terminals, after losing connection, will initiate access on the original frequency band, and will only update the frequency band for access when the original frequency band is unavailable. Following this convention, the network device compares the frequency band the terminal accesses with the priority order of dedicated frequency points, blindly determining the terminal's dedicated frequency priority identifier. After successful terminal access, the RRCrelease contains the determined preceding dedicated frequency priority identifier, which is the priority identifier of the last dedicated frequency point used by the terminal before accessing the target network.

[0066] In another optional embodiment of the present invention, the network device marking the terminal with a dedicated frequency point priority identifier according to a preset rule may include:

[0067] The terminal is assigned a dedicated frequency priority identifier based on its identifier.

[0068] Specifically, the target value is obtained by taking the remainder between the terminal identifier and the preset value; the target value is used to mark the priority identifier of the dedicated frequency point of the terminal.

[0069] In this embodiment, the base station formulates preset rules to obtain the priority identifier of the terminal's preceding dedicated frequency band. The preset rules, for example, allocate different dedicated frequency band priority identifiers to the terminal based on the terminal's C-RNTI or other identifiers that identify the terminal.

[0070] Optionally, network devices can obtain frequency band capacity based on the capabilities of different frequency bands. For example, if the ratio of high frequency band capacity to low frequency band capacity is approximately 10:1, then terminals with C-RNTI (terminal identifier) ​​mod 10 = 1 are configured with priority for low frequency bands, while other terminals are configured with priority for high frequency bands.

[0071] In this embodiment, when the terminal re-establishes access to the target network, the network device with the preceding C-RNTI in the RR Crescent Request (RRC Re-establishment Request) allocates a dedicated frequency priority identifier to the terminal according to the rules described above based on this C-RNTI. For example, C-RNTI mod 10 = 1 is assigned as low-frequency band priority, and others are assigned as high-frequency band priority.

[0072] When a terminal switches to the target network, the network device includes the C-RNTI and the newly added dedicated frequency priority identifier in the RRC context through Xn. The identifier configuration rules are exchanged. Based on the source C-RNTI, the target network device configures a new C-RNTI for the terminal that meets the rules. For example, the new C-RNTI also meets the rules that mod 10 = 1 and the corresponding dedicated frequency priority identifier is configured.

[0073] In this embodiment of the invention, priority identification of dedicated frequency points for interactive terminals is performed between base stations without affecting the core network; only inter-base station communication is possible. This allows for rapid acquisition of the terminal's preceding dedicated frequency point priority identifier, enabling the terminal to quickly access the target network.

[0074] like Figure 2 As shown, in a specific embodiment of the present invention, the process of the terminal network selection method may include:

[0075] Step 1: Public users access the private network;

[0076] Step 2: Determine whether the terminal is in high-speed mode by terminal reporting, network device judgment, or core network judgment;

[0077] Step 3: Determine whether the core network assigns a dedicated frequency priority to the target terminal, and mark the terminal as high-speed or low-speed via RFSP;

[0078] Step 4: If the core network marks the dedicated frequency point priority for the target terminal RFSP and the terminal is in high-speed mode, the base station obtains the dedicated frequency point priority identifier marked by the core network from the core network, configures different dedicated frequency point priority identifiers for the terminal, and the terminal reselects the network according to the dedicated frequency point priority identifier.

[0079] Step 5: If the core network has not marked the dedicated frequency point priority for the target terminal's RFSP, and the terminal is in high-speed mode, then the terminal reselects the network according to the dedicated frequency point priority identifier marked by the base station; this step may include: Step 51: The terminal reports its own preceding dedicated frequency point priority identifier. The base station carries the dedicated frequency point priority identifier and the corresponding dedicated frequency point priority order in the RRC reconfiguration;

[0080] Step 52: Base station blindly determines the priority identifier of the terminal's preceding dedicated frequency point;

[0081] Step 53: The base station formulates preset rules and obtains the priority identifier of the terminal's preceding dedicated frequency point. For example, the base station allocates dedicated frequency point priority to the terminal according to the C-RNTI.

[0082] If the terminal determines that it is in a low-speed state during the above process, the terminal will reselect the network according to the common priority.

[0083] In the above embodiments of the present invention, by configuring a corresponding dedicated frequency point priority for the terminal, the terminal can select a network through the dedicated frequency point priority. This can achieve near-fixed user dedicated frequency point priority, ensuring that the terminal can still use the dedicated frequency point priority for network selection after a long period of time or after switching networks. The dedicated frequency point priority will not become invalid due to time or network switching. This enables differentiated network selection in the idle state and achieves load balancing in the idle state.

[0084] Embodiments of the present invention also provide a terminal network selection method, applied to a network device, the method comprising:

[0085] When the terminal is determined to be in an idle state and a high-speed state, a target signaling is sent to the terminal.

When the terminal accesses the target network, it selects the target network according to the dedicated frequency priority corresponding to the dedicated frequency priority identifier of the terminal and accesses the target network.

[0086] Optionally, the dedicated frequency priority identifier is marked by the core network and obtained by the network device from the core network, or the dedicated frequency priority identifier is marked by the network device.

[0090] The processing module 32 is used to select the target network according to the priority of the dedicated frequency point corresponding to the priority identifier of the terminal's dedicated frequency point when the terminal accesses the target network, and then access the target network.

[0092] Optionally, when the dedicated frequency priority identifier is marked by the core network and obtained by the network device from the core network, the processing module 32 is further configured to:

The network device then uses this priority to identify the preceding dedicated frequency point as the identifier carried in the Radio Link Control Release (RRCrelease) message.
