Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for updating a cell physical layer identifier.
Background
In the 3GPP specification, a self-organizing network (SON) technology TS36.3003 is specially added, and in the specification, a TD-LTE (Time Division Long Term Evolution) system can replace manual operation of a conventional network through autonomous self-organizing functions of self-planning, self-installation, self-configuration, self-optimization, self-healing, self-backhaul, and the like of a radio access network, so that participation of operation and maintenance personnel can be greatly reduced, and network construction and operation and maintenance costs of an operator can be reduced.
The self-configuration can greatly reduce the process of manually and repeatedly configuring parameters in the network opening process, PCI (Physical layer Identity) self-configuration is used for Physical Cell Identity PCI code configuration, and each base station can automatically select the Physical Cell Identity through the self-configuration of the system. The 3GPP protocol specifies 504 PCI codes with pseudo-random numbers, which are identifiers of cell identification and channel Synchronization in the TD-LTE network, and are determined by PSS (Primary Synchronization Signal) and SSS (secondary Synchronization Signal) together, and if the PCI codes are not properly configured, cell Synchronization is firstly affected, and cell interference is secondly generated. In practical networking application, different cells with the same PCI code must appear in the PCI code configuration with a limited number, and in order to avoid interference between cells and correctly identify each neighboring cell, the PCI code configuration needs to satisfy the following two conditions:
1) no conflict: any two adjacent cells with the same frequency cannot use the same PCI code;
2) not to be confused: the same PCI code can not be used by any two cells with the same frequency in all adjacent cells of one cell;
the first condition ensures that the UE distinguishes between different adjacent cells because the UE cannot distinguish between two adjacent cells with the same frequency and PCI code. The second condition ensures that the current cell can correctly identify two adjacent cells, because the UE reports the measurement report after entering the cell edge zone, the measurement report identifies different cells by PCI codes, and if two same-frequency adjacent cells of the current serving cell have the same PCI code, the serving cell cannot distinguish which adjacent cell the UE measurement report is for, and therefore cannot make a correct handover decision, and the UE cannot normally handover between cells.
However, most mobile communication networks in the existing networks are configured by combining a plurality of factory devices according to a chip area, and PCI multiplexing often occurs in handover areas of the factory devices, which causes PCI collision and confusion among adjacent cells of different manufacturers. When different manufacturers deal with the PCI problem, the PCI code configuration conditions of other manufacturer equipment areas cannot be collected and detected, and the PCI code reconfiguration can be attempted only for multiple times so as to avoid conflict confusion.
Therefore, how to implement the inter-vendor networking auto-negotiation to solve the PCI conflict confusion is an urgent problem to be solved at present.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Referring to fig. 1, a flowchart illustrating steps of a method for updating a cell physical layer identifier according to an embodiment of the present invention is shown, where the method may be applied to a first base station, and specifically may include:
step 101: and sending a cell physical layer identification list updating request message to the second base station.
In the embodiment of the invention, the first base station and the second base station are adjacent alien base stations. Because the base stations of the same manufacturer can record the PCI codes and allocate different PCI codes to each base station of the same manufacturer, the situation of the same manufacturer is not considered in the embodiment of the invention.
When the first base station needs to update the local PCI code, an initialization request message is sent to the adjacent second base station, and the initialization request message contains a cell physical layer identification list updating request message used for requesting an effective cell physical layer identification list of the second base station.
In the embodiment of the present invention, a Message Type field may also be added to the initialization request Message, so as to indicate the Type of the initialization request Message, so that the second base station may perform Message Type identification according to the Message Type field. As shown in table 1 below, a list of Message Type fields provided by an embodiment of the present invention is shown:
table 1:
as shown in table 1, the new increment "16" in the Message Type table is PCIList Update, and is used to identify the PCIList Update Message Type of the present solution. The Message Type field is assigned 16 when a RESOURCE STATUS REQUEST Message is constructed, i.e. this Message is identified as a PCIlist update REQUEST Message.
Of course, in practical applications, a person skilled in the art may use other ways to perform sending the PCIlist update request message, and the embodiment of the present invention is not limited thereto.
In a preferred embodiment of the present invention, before the step 101, the method may further include:
step S1: detecting whether a cell physical layer identification conflict event exists; and if so, sending a cell physical layer identifier list updating request message to the second base station.
In the embodiment of the present invention, first, the first base station needs to detect whether there is a PCI code collision confusion situation locally, and if there is a PCI code collision confusion situation, sends a cell physical layer identifier list update request message to the second base station to obtain an effective cell physical layer identifier list of the second base station, and updates the local PCI code.
Upon detecting that there is a PCI code collision confusion event in the reverse home, step S2 is executed.
In another preferred embodiment of the present invention, after the step S1, the method further includes:
step S2: and judging whether an X2 link is established between the first base station and the second base station.
In the embodiment of the present invention, in the process of updating the PCI code by the first base station and sending a message between the first base station and the second base station, an X2 link needs to be established between the first base station and the second base station, so as to perform mutual transmission of the message.
Thus, when there is a PCI code collision confusion event in the first base station, it is further determined whether an X2 link has been established with the second base station, if an X2 link has been established between the first base station and the second base station, sending a PCIlis (cell physical layer identity list) request response message from the first base station to the second base station is performed, otherwise, step S3 is performed.
Step S3: and starting a delay counter to count the times.
And when the first base station and the second base station do not establish the X2 link, starting a delay counter to establish the X2 link between the first base station and the second base station.
A threshold number of times, for example, 3 times, or 5 times, etc., may be preset, and this is not limited in the embodiment of the present invention.
When the counted times of the delay counter is greater than or equal to the threshold times, the X2 link establishment between the first base station and the second base station is failed, and the processing flow is quitted; and when the statistical times are less than the threshold times and the X2 link between the first base station and the second base station is successfully established, entering a PCIlist message processing flow and sending a RESOURCE STATUS REQUEST message to the second base station.
After the first base station sends the cell physical layer identity list update request message to the second base station, step 102 is entered.
Step 102: receiving a cell physical layer identifier list request response message returned by the second base station; wherein the request response message contains a second time difference.
In the embodiment of the present invention, after receiving a PCIlist update request message sent by a first base station, a second base station returns a PCIlist update request response message to the first base station, where the PCIlist update request response message includes a second time difference, and the second time difference is an absolute value of a difference between a time when the second base station receives the PCIlist update request message and a time when the cell physical layer identifier list request response message is sent.
And step 103 is entered when the first base station receives a cell physical layer identity list request response message returned by the second base station.
Step 103: and when the first time difference is larger than the second time difference, receiving a second effective cell physical layer identification list sent by the second base station.
In the embodiment of the present invention, after receiving a PCIlist request response message returned by a second base station, a first base station calculates a first time difference, where the first time difference is an absolute value of a difference between a time when the first base station sends the PCIlist update request message and a time when the PCIlist request response message is received.
And when the first time difference is greater than the second time difference, the situation that the PCI code conflict confusion exists in the first base station is indicated, a request message of effective PCIlist is sent to the second base station, and the second base station calculates the second effective PCIlist after receiving the request message of the effective PCIlist sent by the first base station and sends the calculated second effective PCIlist to the first base station.
In practical applications, a commonly used calculation method in the prior art scheme may be adopted for calculating the second effective PCIlist, and the embodiment of the present invention does not limit this.
In a preferred embodiment of the present invention, when the first time difference is smaller than the second time difference, the method may further include:
step N1: calculating by adopting a preset algorithm to obtain a first effective cell physical layer identifier list;
step N2: and sending the first effective cell physical layer identifier list to the second base station so that the second base station updates the cell physical layer identifier by using the first effective cell physical layer identifier.
In the embodiment of the present invention, there is another case that the first time difference is smaller than the second time difference, which indicates that the processing delay of the PCIlist message by the first base station is small, and in this case, the first base station calculates the first valid PCIlist by using a preset algorithm, and sends the first valid PCIlist to the second base station, so that the second base station updates the local PCI of the second base station by using the first valid PCIlist, so as to solve the problem of PCI collision and confusion.
It is to be understood that 8 valid PCI values may be respectively included in the first valid PCIlist and the second valid PCIlist, so that the first base station and the second base station may update the local PCI using the valid PCI values.
Of course, the effective PCIs in the first effective PCIlist and the second effective PCIlist are not limited to 8, but may be 10 or 6, and the like, which is not limited in this embodiment of the present invention.
Further, after receiving the second valid PCIlist sent by the second base station, the first base station proceeds to step 104.
Step 104: and updating the physical layer identifier of the local cell by utilizing the second effective cell physical layer identifier list.
When the first base station receives the second effective PCIlist sent by the second base station, the effective PCI in the second effective PCIlist is extracted to update the local PCI, and therefore the problem of PCI conflict and confusion existing locally in the first base station is solved.
Certainly, when the local PCI is updated by using the second valid PCIlist sent by the second base station, there may be a case of failure in updating, and when the local PCI of the first base station fails to be updated, a message of failure in updating is sent to the second base station, so that the second base station recalculates the second valid PCIlist, and sends the recalculated second valid PCIlist to the first base station, so that the first base station continues to update the local PCIlist.
In practical applications, a person skilled in the art may set the number of times of sending the second valid PCIlist, for example, 1 time, or 3 times, and when the set number of times is reached, no matter whether the first base station uses the second valid PCIlist to update the local PCI or whether PCI collision confusion exists, the sending of the second valid PCIlist is not performed. Of course, the second base station may continue to send the second valid PCIlist to the first base station under the condition that the first base station does not resolve the local PCI collision confusion, which is not limited in the embodiment of the present invention.
The embodiment of the invention provides a cell physical layer identifier updating method, which is applied to a first base station and used for sending a cell physical layer identifier list updating request message to a second base station; the first base station and the second base station are adjacent base stations of different manufacturers and receive a cell physical layer identifier list request response message returned by the second base station; the request response message includes a second time difference, where the second time difference is an absolute value of a difference between a time when the second base station receives the cell physical layer identifier list update request message and a time when the cell physical layer identifier list request response message is sent, and when the first time difference is greater than the second time difference, the second effective cell physical layer identifier list sent by the second base station is received, and the first time difference is an absolute value of a difference between a time when the first base station sends the cell physical layer identifier list update request message and a time when the cell physical layer identifier list request response message is received, and the second effective cell physical layer identifier list is used for updating the local cell physical layer identifier. Therefore, the embodiment of the invention can realize the automatic negotiation of the inter-vendor networking and solve the problem of PCI conflict confusion.
