The following specifically describes above-mentioned processing details.
(1) step S202
Before carrying out this step; NRIF obtains the log-on message of wireless device, and confirms the information of the BAP(broadband access point) of wireless device according to log-on message, and concrete is operating as: step 1; FCS receives the register requirement from wireless device; Wherein, carry Internet protocol (IntemetProtocol the abbreviates IP as) address of device number and the wireless device of the wireless device public network under current in the register requirement; Step 2, FCS constructs register requirement, is met the posttectonic register requirement of forwarding form and sends to NRIF; Step 3, NRIF obtains posttectonic register requirement, confirms the ID (Identifier) of the BAP(broadband access point) of wireless device according to the IP address of the public network that carries in the posttectonic register requirement.
At this moment; The geographical position planning information that NRIF confirms wireless device according to the broadband access dot address of wireless device (preferably; Geographical position planning information can be Cell Global Identity (Cell Global Identity; Abbreviate CGI as), CGI is in global system for mobile communications (Global System for Mobile Communication abbreviates GSM as); Be used for indicating a base station sub-system or base station cell), concrete is operating as: NRIF confirms the geographical position planning information corresponding with the ID of this BAP(broadband access point) according to the ID of the BAP(broadband access point) of confirming with the predetermined corresponding relation of geographical position planning information.
(2) step S204
NRIF sends to FCS with geographical position planning information; FCS confirms corresponding base station controller and the configuration information of the base station controller of confirming is sent to wireless device; Concrete is operating as: FCS is according to the corresponding relation of geographical position planning information with a plurality of base station controllers that are provided with in advance; And in a plurality of base station controllers, select the lightest base station controller of load, and the IP address and the ID of the base station controller of selecting sent to wireless device as configuration information.In concrete implementation process; Each base station controller all has the CGI of planning in the base station controller pond; Therefore can find the available base station controller pond according to CGI; At first judge the main base station controller load condition of using,, then select the access base station controller of subsequent use base station controller C for use as wireless device if main with the heavier or fault of base station controller load.
(3) step S206
Wireless device sends the request of access according to configuration information to base station controller and inserts to carry out; Concrete is operating as: wireless device sends the access requested operation to base station controller and is specially: step 1; Wireless device sends the request of access to base station controller; Wherein, insert the device number that carries wireless device in the request; Step 2, base station controller are obtained the request of inserting, and the device number of wireless device is notified to FCS and to the wireless parameter of FCS acquisition request wireless device; Step 3, FCS returns the wireless parameter of wireless device according to device number to base station controller, and base station controller is accepted the access of wireless device according to wireless parameter.
Fig. 3 shows the modern handling process of letter of wireless device dynamic access method according to the preferred embodiment of the invention, and as shown in Figure 3, this handling process comprises step 302 to step 326.
At first, before carrying out above-mentioned steps, the function of NRIF and FCS is described.
The mapping relations of mapping relations, IAF and the wireless network planning CGI of BAP(broadband access point) IAF (Identifier of Femto Access), IAF and the geographical position latitude and longitude information of all broadband IP addresses, broadband IP address correspondence in the fixed network coverage of NRIF preservation operator.
BSC is active and standby with relation, BSC load condition, BSC running status, the URL (UniformResource Locator abbreviates URL as) of BSC, the security gateway (Security Gateway abbreviates SGW as) of BSC in the mapping relations of FCS preservation CGI and BSC, the BSC pond.Wherein, the information such as SGW of the mapping relations of CGI and BSC, the URL of BSC, BSC are advance planning, static configuration, and active and standby the using of BSC concerns it is relative in the BSC pond; In the practical implementation process; For a CGI zone, consider system's connection reliability and radio function reliability (for example sub-district switching), generally specify a master to use BSC; On wireless planning near the subsequent use BSC of this regional conduct, and this subsequent use BSC can be the master in another CGI zone use BSC.
And, support soap protocol between FCS and the NRIF based on HTTP.
Be elaborated in the face of this signaling process flow process down.
Step 302, FCS sends link detecting message to BSC, detects the load condition of BSC, and the running status of BSC all dynamically updates through the heartbeat detection message of FCS and all BSC;
Step 304, BSC is to FCS feedback heartbeat detection message, wherein; Carry the load condition of BSC in the heartbeat detection message; Whether FCS moves normally according to heartbeat detection message determining BSC, then thinks the BSC operation troubles like the heartbeat detection message of not receiving BSC for three times, and handling process finishes; Move under the normal situation execution in step 306 at BSC;
Step 306, FCS receives the register requirement of Femto-node, and wherein, this register requirement carries Femto-node ID and public network IP address;
Step 308, FCS resolves the login request message of Femto-node, obtains wherein Femto-node ID and public network IP address;
Step 310, FCS is to NRIF transmitting apparatus on-position Location Request;
Step 312; NRIF receives the said equipment on-position Location Request; Resolve Femto-node ID and Femto-node public network IP address in this request, judge at first whether Femto-node ID belongs to legitimate device, as do not conform to rule echo reply message; Refusal Femto-node inserts, and flow process finishes;
If this Femto-node belongs to legitimate device, then begin to judge public network IP address, the BAP(broadband access point) IAF that inquiry is corresponding.Need to prove that NRIF can carry out the authentication that whether inserts at legitimate ip address to Femto-node here;
NRIF continues the geographical position planning information at inquiry IAF place, for example CGI according to the IAF that inquires;
Step 314, NRIF carries the geographical position planning information that inquires to FCS home position location response message in this message;
Step 316; FCS preserves the geographical position planning information that NRIF returns; According to the corresponding relation of this geographical position planning information with a plurality of BSC that are provided with in advance; And in a plurality of BSC, select the lightest BSC of load, and IP address and the ID of the BSC that selects sent to Femto-node as configuration information;
Step 318, FCS is handed down to Femto-node with the initializes configuration information of the BSC (URL that comprises BSC, the SGW of BSC) that confirms;
Step 320, Femto-node receives the initial configuration message of FCS, carries out initialization operation;
Step 322, Femto-node initiates to insert request to the BSC of appointment;
Step 324, BSC receives the access request of Femto-node, to the wireless parameter of this Femto-node of FCS request;
Step 326, FCS returns the wireless parameter (comprising the CGI that obtains from NRIF) of specifying Femto-node to BSC, and BSC receives the wireless parameter of Femto-node, and so far, dynamically access process finishes, and BSC and Femto-node get into the normal wireless operation flow.
By means of embodiments of the invention; Through confirming the geographical location information of Femto-node; And be that Femto-node selects the lighter base station controller of load according to this geographical location information; Through above-mentioned can the uniform distribution base station controller, alleviate the load of base station controller, improved the reliability of resource utilization and access.
