Description
Technical Field

Background
At present, data services are increasingly expanded, and operators continuously improve their competitiveness to guarantee that the operators occupy a place in the future communication market; for example, a fixed network and a mobile network are integrated, and a technology that is very much concerned is to implement indoor coverage by home (e) NodeB (home base station, hereinafter abbreviated as h (e) NB), and implement rich wireless data services by a fixed network access network, so as to improve the speed and flexibility of the data services, meet the requirement of efficient access, and make full use of the established fixed network, thereby reducing the investment in each aspect of the construction cost, the operation cost, the terminal user management cost, and the like of the mobile wireless access network.
In an h (e) NB network architecture in the prior art, a SeGW (Serving GateWay), an HMS (Hybrid Management Sub-layer), an h (e) NB GW (home (e) NodeB GateWay), and other functional entities are disposed between an h (e) NB and a core network, where the SeGW and the HMS may be integrated in the h (e) NB GW or may exist as independent network elements. H (e) NB is accessed to h (e) NB GW through IP Network, and h (e) NB GW provides an interface for h (e) NB to access to wireless Network, is responsible for registration and access control of h (e) NB or UE (user terminal), and also provides a convergence or forwarding function for information interaction between h (e) NB and CN (Core Network). The SeGW establishes an IPSec (Internet Protocol Security) channel between the SeGW and the H (e) NB, and realizes the authentication, authorization and encryption and integrity protection of transmission data of the H (e) NB through the IPSec Security channel. The HMS performs Network Management on the h (e) NB, for example, TR-069 or SNMP (Simple Network Management Protocol) is used to implement Management functions such as configuration, acquisition, and alarm of the h (e) NB.
Currently, when accessing a network for an h (e) NB, the following method is adopted for configuring parameters for the h (e) NB: h (e) NB sends a self-configuration parameter request message to an OMC (operations Maintenance Center, operation Maintenance Center) on the network side; the OMC acquires Self-configuration parameters from a Self-Organized Network Server (SON) Server and sends the acquired Self-configuration parameters to H (e) NB. In the prior art, although the self-configuration of the h (e) NB can be realized according to the self-configuration parameters acquired by the SON Server, the self-configuration parameters stored by the SON Server are usually fixed and static parameters, so that the h (e) NB can only be configured according to the fixed and static parameters during the self-configuration, and therefore, the h (e) NB may not adapt to the change of the wireless network environment (such as the change of the actual load and the congestion condition of the network) in the subsequent working process, which may cause the problems of disordered work, low working efficiency, poor self-adaptation capability, and the like.

In the latter case, h (e) NB may further adjust the configuration parameters according to its own operation information, and load the adjusted configuration parameters in the optimization adjustment request response to send to the PSCOS, and verify whether the adjustment is appropriate by the PSCOS, and if not, adjust the configuration parameters according to the stored operation information by the PSCOS.
It should be noted that, h (e) NB may be self-configured in an existing manner before self-optimization, but is preferably self-configured in a manner provided by the embodiment of the present invention.
To describe the embodiment of the present invention in more detail, the embodiment of the present invention is described by taking the example of self-configuration of the newly added h (e) NB in the wireless network.
Referring to fig. 2, a system architecture diagram of self-optimization and self-configuration of an access network node in the embodiment of the present invention includes a PSCOS1, a SeGW2, a DNS 3(Domain Name Server), a Provisioning H (e) NB GW 4(H (e) NB configuration gateway), a Serving H (e) NB GW 5(H (e) NB service gateway), and a newly added H (e) NB 6.

The policy storage module 12 may be a directory system or a database system.

And the software/hardware data storage module 15 is used for storing version information, patch information and the like required by remote software and hardware upgrading.
Referring to fig. 3, a signaling flow chart of h (e) NB self-configuration based on the network architecture shown in fig. 2 in the embodiment of the present invention is shown, and the flow includes the following steps:
steps 301 to 302, h (e) NB6 turns on the power supply to be put into use, and establishes a secure channel between h (e) NB6 and ProvisioningSeGW 2.
Step 303, h (e) NB6 sends a domain name resolution request to DNS 3 through the IP network.
In this step, the Domain Name resolution request includes a Full Qualified Domain Name (FQDN) of the Provisioning H (e) NB GW 4(H (e) NB configuration gateway) to obtain an IP address of the Provisioning H (e) NB GW 4 corresponding to the FQDN.
Step 304, the DNS 3 acquires the IP address corresponding to the FQDN according to the domain name resolution request, and sends the IP address to h (e) NB6 in the domain name resolution response.
305-306, establishing a transmission session secure channel between an NB6 (H) (e) and a Provisioning H (e) NB GW 4, where the transmission session secure channel may be established based on a Stream Control Transmission Protocol (SCTP); h (e) NB6 uses the secure tunnel to send a Serving-GW discovery request (Serving-GW discovery request) to Provisioning H (e) NB GW 4. The service gateway discovery request may include h (e) location information of NB6, node identification information (e.g., ID information), capacity requirement information, and the like.
Step 307, Provisioning H (e) NB GW 4 sends a Serving-GW Discovery Policy Request (Serving-GW Discovery Policy Request) to PSCOS1 according to the Serving-gateway Discovery Request.
The service gateway discovery policy request includes h (e) location information of NB6, node identification information (e.g., ID information), capacity requirement information, and the like.
Step 308, the PSCOS system 1 configures a service gateway for h (e) NB6 according to the stored operation information according to the service gateway discovery policy request.
In this step, based on the structure of the PSCOS1 shown in fig. 2, the process of configuring the service gateway may be: after receiving the request sent by Provisioning H (e) NB GW 4, the transceiver module 17 reads the performance data stored in the storage module 16 and the parameter configuration Policy stored in the self-configuration Policy storage submodule 122 by the allocation module 18, configures the service gateway for H (e) NB6, and sends the address information of the configured service gateway to the Provisioning H (e) NB GW 4 by loading the address information of the configured service gateway in a service gateway Discovery Policy Response (Serving-GW Discovery Policy Response).
The allocating module 18 is configured to configure the service gateway for h (e) NB6, specifically: the allocation module 18 reads the storage module 16, obtains geographical location information, access status information, channel interference information, congestion status information, and the like of each service gateway in the wireless network, then makes a decision according to policies about load balancing, congestion control, and the like in the self-configuration policy storage sub-module 121 in the query policy storage module 12, and according to node identification information, location information, capacity requirement information, and the like of H (e) NB6 carried in the received service gateway discovery policy request, selects the Serving H (e) NBGW 5 with a lighter current load and better signal strength as the Serving gateway of H (e) NB6, and carries the IP address of the Serving H (e) NB GW 5 in the policy response to send to the Serving H (e) NB GW 4.
Step 309, Provisioning H (e) NB GW 4 sends a Serving-GW Discovery Response (Serving-GW Discovery Response) to H (e) NB6 according to the Serving-gateway policy Response.
In this step, the Serving gateway discovery response includes the IP address information of the Serving SeGW (not shown in the drawings) and the Serving H (e) NB GW 5.
Step 310, H (e) NB6 stores the received IP address information of Serving SeGW and Serving H (e) NB GW 5.
311-312, establishing a secure channel between H (e) NB6 and Serving H (e) NB GW 5 and a reliable transmission session channel of a well-defined port in Serving H (e) NB GW 5.
The secure channel and the Transmission session channel may be established based on TCP (Transmission Control Protocol) or SCTP.
Step 313, H (e) NB6 sends a registration request (registerequest) to Serving H (e) NB GW 5.
The registration request includes registration type information, h (e) location information and identification information (e.g., ID information) of NB 6.
Step 314, Serving H (e) NB GW 5 controls access to H (e) NB6 according to the registration Request, determines whether to allow the H (e) NB6 to register, and if so, sends a Parameter Configuration Policy Request (Parameter Configuration Policy Request) to PSCOS 1.
Preferably, Serving H (e) NB GW 5 may further send a registration failure notification message to H (e) NB6 when determining that H (e) NB6 registration is not allowed.
Steps 315-316, the PSCOS1 generates configuration parameters for h (e) NB6 according to the stored operation information, and sends the generated configuration parameters to servingh (e) NB GW 5.
In this step, PSCOS1 generates configuration parameters for h (e) NB6, specifically: after the transceiver module 17 receives the configuration parameter Policy request, the generating module 13 reads the storage module 16 to obtain the wireless parameter information of the neighboring cell of the cell where H (e) NB6 is located, and configures the Policy (such as the policies of site coverage, interference detection, etc.) according to the parameters stored in the self-configuration Policy storage sub-module 121, generates the configuration parameters (the configuration parameters may include cell identification code, pilot subcarrier, pilot power, antenna downtilt angle, cluster information (such as location area, routing area), start subcarrier information, neighbor cell list (such as cell identification code, IP address, etc.) for H (e) NB6, and loads the generated configuration parameters in a parameter configuration Policy Response (parameter configuration Policy Response) to send to the Serving H (e) NB GW 5.
Step 317, Serving H (e) NB GW 5 loads the configuration parameters carried by the parameter configuration policy response in a registration response according to the configuration parameter policy response, and sends the configuration parameters loaded by the parameter configuration policy response to H (e) NB 6.
Step 318, h (e) NB6 performs self-configuration according to the received configuration parameters.
Preferably, the generating module 13 may further determine whether the policy stored in the policy storage module 12 is expired according to the operation information stored in the storage module 16, and if the policy is expired, start a policy updating process.
Preferably, the generating module 13 determines whether there is a network fault according to the operation information stored in the storage module 16, and if so, sends instruction information to the work order dispatching module 14 to instruct the work order dispatching module 14 to notify the operation and maintenance staff of maintaining the network fault in a form of dispatching the work order.
The H (e) NB can be put into use through the process, and when the self-configuration is carried out, the H (e) NB carries out the self-configuration according to the configuration parameters generated by the PSCOS according to the change condition of the current wireless network, so that the H (e) NB after the self-configuration can be more suitable for the current wireless network environment, and the problem that the access network node in the prior art can only carry out the configuration according to the fixed or static configuration parameters, so that the self-adaptation capability of the access network node is poor is solved.
It should be noted that the PSCOS may also generate configuration parameters only for the h (e) NB, instead of selecting a serving gateway for the h (e) NB, which also can solve the problem that the access network node in the prior art is poor in adaptive capability due to the fact that the access network node can only be configured according to fixed or static configuration parameters to a certain extent.
In order to enable the H (e) NB to better adapt to the change of a wireless network environment in the using process, the embodiment of the invention also provides a process of H (e) NB self-optimization, the PSCOS stores the operation information of the wireless network, and the stored operation information is updated after the PSCOS receives the operation information reported by each network node; in combination with practical applications, the embodiment of the present invention provides two self-optimization flow triggering methods: the method comprises the steps that when PSCOS determines that the parameter configuration of H (e) NB needs to be adjusted according to stored operation information, a self-optimization process is triggered; in the second mode, after receiving the request for adjusting the configuration parameters sent by h (e) NB, the PSCOS triggers the self-optimization process.
Referring to fig. 4A, which is one of signaling flow diagrams of h (e) NB self-optimization based on the network architecture shown in fig. 2 in the embodiment of the present invention, after the h (e) NB implements self-configuration, the flow includes the following steps:
step 401, the PSCOS1 obtains the configuration parameters of h (e) NB6 stored therein, determines whether the configuration parameters of h (e) NB6 need to be adjusted, and if so, adjusts the obtained configuration parameters according to the stored operation information.
In this step, the PSCOS1 determines whether the parameter configuration of h (e) NB6 needs to be adjusted, specifically: reading the software/hardware version information stored in the software/hardware data storage module 15, and determining that the parameter configuration of h (e) NB6 needs to be adjusted when the hardware or software version of h (e) NB6 is over time or the network performance of h (e) NB6 is reduced according to the operation information reported by h (e) NB 6.
Step 402, the PSCOS1 sends an Optimization configuration parameter Message (Optimization configuration parameter Message) including the adjusted configuration parameters or software/hardware version information to h (e) NB 6.
Step 403, h (e), NB6 adjusts configuration parameters or updates the software/hardware version according to the parameter optimization policy message.
Referring to fig. 4B, a second signaling flow chart of h (e) NB self-optimization based on the network architecture shown in fig. 2 in the embodiment of the present invention is shown, where after the h (e) NB implements self-configuration, the flow includes the following steps:
step 401', h (e) NB6 collects network performance data reported by the UE and/or other network nodes (e.g. other h (e) NB), and performs pre-optimization on relevant parameters according to an optimization decision threshold of the collected performance data trigger parameters.
In this step, h (e) the cell in which NB6 is located starts pre-optimization according to performance data of the neighboring cell or/and fault alarm information (e.g., high call drop rate, frequent handover, etc.), or triggers an optimization decision threshold according to the fault alarm information. H (e) the cell in which the NB6 is located performs pre-optimization (for example, deleting a failed cell from the neighbor cell list) on the neighbor cell list and the relevant parameters of the neighbor cell according to the acquired wireless network data information, event measurement information, and interference detection algorithm of the neighbor cell, and adjusts the signal strength value of the cell in which h (e) the NB6 is located.
Step 402', H (e) NB6 sends an optimization adjustment request (optimization AdjustRequest) to PSCOS 1.
The optimization adjustment request includes h (e) a pre-optimization result obtained by pre-optimizing the configuration parameters by the NB6 according to the wireless network performance data, and performance data related to the pre-optimization result.
Step 403', the PSCOS1 verifies and adjusts the optimization result of h (e) NB6 according to the received pre-optimization result and the performance data related to the pre-optimization result.
In this step, when the transceiver module 17 of the PSCOS1 receives the optimization adjustment request, the adjustment module 19 comprehensively considers, verifies, and adjusts the optimization result according to the information stored in the storage module 16, the policy information such as neighbor optimization, interference detection, and the like in the policy storage module 12, and the performance information carried in the optimization adjustment request, and updates the operation information stored in the storage module 16.
Step 404', the PSCOS1 sends the verified and adjusted configuration parameters to h (e) NB6 in an optimization adjustment Response (optimization adjustment Response).
Steps 405', h (e) NB6 optimizes parameters of the neighbour list and neighbour cells according to the verified, adjusted configuration parameters.
Through the self-optimization process, the configuration parameters can be adjusted according to the self running condition in the use process of the H (e) NB, the adjusted configuration parameters are sent to the PSCOS for verification, the PSCOS further adjusts the configuration parameters according to the stored running information, so that the H (e) NB performs self-optimization according to the adjusted configuration parameters of the PSCOS, the configuration parameters of the H (e) NB are more adaptive to the change of a wireless network environment, and the self-adaption capability of the H (e) NB is further improved.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
