Description
Technical Field
The invention relates to a neighboring cell information management technology of wireless communication, in particular to a method and a system for managing same-frequency neighboring cell information.
Background
Ensuring service continuity for mobile subscribers is a basic function of cellular mobile communication systems, and handover of a mobile station serving cell is a primary means of ensuring service continuity. In order to facilitate switching of User Equipment (UE), a system needs to configure an adjacency relation for each cell, so that a network side notifies the user equipment of neighboring cell information, the user equipment reports a measurement result after measuring the neighboring cell, and the network side instructs the user equipment to switch a certain neighboring cell.
Which neighbouring cells are around a cell are not only related to the cell distance but also closely related to the radio environment in which the cell is located. Due to the complex wireless environment, especially the dense urban environment of high-rise buildings, it is difficult to exactly judge which neighboring cells should be configured for a certain cell at the initial stage of network planning. Some systems are added with a cell or the property of the cell is changed, and the adjacent relation of the cell is not updated in time; or the change of the environment, omission in the configuration of the network planner and the like can cause the update of the information of the neighboring cells to be untimely. Therefore, the user equipment cannot be switched to other cells in time, so that the conditions of overhigh load of the cell, poor signal quality of the cell, serious interference, call drop of a user and the like occur; the cell is a cell of a signal currently used by the user equipment.
The cell information is composed of cell physical layer information and cell high-level information, wherein the cell physical layer information is a Primary Scrambling Code (PSC) of a cell, and the PSC is unique in a certain area during network planning; the cell high-level information includes: public Land Mobile Network (PLMN) and cell unique identifier (CID) in PLMN, or comprises: PLMN, Routing Area Identity (RAI) and Location Area Identity (LAI), or comprises: PLMN, RAI, LAI and CID.
If certain cells are associated with soft handover and user information can be sent from these cells, these cells are called the active set. For intra-frequency virtual active set cells, only the currently used frequency is considered here, so the virtual active set is equal to the active set. The intra-frequency neighbor cell list consists of an active set cell and a monitoring set cell, and the active set and the monitoring set have no intersection; the monitoring set cell is a cell which does not belong to the active set in the intra-frequency adjacent cell list; and the active set cells not included by the intra-frequency neighbor cell list are not subjected to event estimation and measurement reporting by the user equipment.
In order to configure the Neighbor Relation of a cell in time, it is proposed in the Long Term Evolution (LTE) system to add an intra-frequency Neighbor list based on an Automatic Neighbor Relation (ANR) function. The ANR function is to assist the ue to measure the physical layer information of a new cell and report the physical layer information to the network side, and to obtain the high-level information of a specific cell, so that the network side completes the function of adding the intra-frequency neighbor list without manually adding neighbor cells, and the system automatically completes the function.
For the problem of missed distribution of the neighboring cells with the same frequency, the prior art can solve the problem through a detection set measurement scheme, when a user equipment reports a detection set report, and a cell detected by the user equipment has corresponding high-level information on a network side, the network side can add the cell measured by the user equipment to a missed distribution intra-frequency neighboring cell list. However, when the ue is in the state of controlling the device across the wireless network, the cell detected by the ue does not have corresponding high-level information on the network side, and even if the signal quality of the cell detected by the ue is good, the high-level information of the cell is unknown, and cannot be added to the missed intra-frequency neighbor list, and even cannot be soft-handed over or hard-handed over to the cell, the ue cannot be timely handed over to another cell, so that the load of the cell is too high, the signal quality of the cell is poor, the interference is severe, or the user drops the call.

The following detailed description of the implementation and principles of the method of the present invention is provided in connection with specific embodiments.
Taking a network side as a radio network controller and a measurement intra-frequency detection set cell as an example, the method for managing information of neighboring cells with the same frequency in the embodiment includes, as shown in fig. 3, the following steps:
step 301: a radio network controller sends a notification message to user equipment, wherein the notification message carries an indication for notifying the user equipment to measure and report intra-frequency cells outside an intra-frequency neighboring cell list;
here, the notification message may be a system broadcast message, a measurement control message, or other downlink messages;
the notification message carries an indication for notifying the user equipment to measure and report the intra-frequency cells outside the intra-frequency neighbor cell list, that is, a field is added or multiplexed in the notification message, and a report cell state cell is placed, wherein the report cell state cell indicates that the intra-frequency cells outside the intra-frequency neighbor cell list which need to be measured and reported are intra-frequency detection set cells;
the notification message further carries a trigger condition cell, the reporting trigger condition is set as intra-frequency detection set cell trigger, and the intra-frequency detection set cell trigger event is set as a 1a event. When a 1a event is employed, the values of the event thresholds for the ANRF and the event thresholds for the handover may be the same or different. If the values of the event threshold for the ANRF event and the event threshold for the handover are the same, it may be required to report both the required handover event and the required ANRF event in the same notification message; if the values of the event threshold for the ANRF event and the event threshold for the handover are different, reporting may be required at the next notification message for the desired ANRF event.
Further, in this step, in order to save power for the ue, the number of the intra-frequency cells reported may be controlled, for example, the notification message further carries a cell number indication cell for indicating the maximum number of the intra-frequency cells to which the measurement result belongs in the report message of the ue, which may be one to multiple, where the number of the cell number indication cells in this embodiment is five.
Step 302: after receiving the notification message, the user equipment measures according to the intra-frequency cell outside the intra-frequency neighbor cell list indicated in the notification message, and reports the physical layer information and the measurement result of the intra-frequency cell;
when the user equipment measures the intra-frequency cells out of the intra-frequency neighbor cell list, the measured physical quantity can be the ratio of the energy of the common pilot channel chip to the band-limited white noise power spectral density, the common pilot channel received signal code power, the main common control physical channel received signal code power, the time slot signal code power interference path loss and the like;
further, the user equipment learns that the reporting trigger condition is intra-frequency detection set cell triggering according to a trigger condition cell carried in the notification message, and the set intra-frequency detection set cell trigger event is a 1a event, the user equipment compares the measurement result with an event threshold, and reports the measurement result to the network side when the measurement result exceeds the threshold, where the measurement result may be an event result or an event result and a measured physical quantity value.
Step 303: the wireless network controller determines the intra-frequency cells needing to be added into the intra-frequency neighbor cell list according to the measurement result, and judges whether the physical layer information of the intra-frequency cells needing to be added into the intra-frequency neighbor cell list has corresponding high-layer information; if yes, go to step 306; if not, go to step 304;
step 304: a wireless network controller sends a notification message to user equipment, wherein the notification message carries physical layer information of a cell in a specified frequency;
here, the specified intra-frequency cell is an intra-frequency cell which has no corresponding high-level information in physical layer information and needs to be added into an intra-frequency neighbor cell list;
the notification message carries physical layer information of the cell in the specified frequency, and the physical layer information of the cell in the specified frequency can be added with a field or multiplexed with a field;
the notification message may be a system broadcast message, or a measurement control message, or other downstream message. If the cell is a measurement control message, an Intra-frequency system information acquisition (Intra-frequency SI acquisition) cell may be reused, and the specific structure is shown in table 1, where a secondary cell Intra-frequency system information acquisition information (Intra-frequency SI acquisition Info) cell in a Primary cell frequency division multiplexing mode FDD is an array, the length of the array is the total number of the designated cells, each group member includes physical layer information, i.e., a Primary Scrambling Code (Primary Scrambling Code) cell, and the Primary Scrambling Code cell fills the corresponding Primary Scrambling Code of the designated cell.
