Embodiment
Embodiment one:
Please refer to Fig. 2, be the forwarding message approach flow chart of the embodiment of the invention.
Step 201.RAN node receives the initial direct-sending message carry cell identification number.The RAN node can for radio network controller (Radio Network Controller, RNC).When wireless area receives the initial direct-sending message that UE sends, in initial direct-sending message, add the identification number of this wireless area, and the initial direct-sending message that will carry cell identification number sends to the RAN node.
Step 202.RAN node obtains the cell identification of carrying in the initial direct-sending message number.The RAN node can identify this message and send from that wireless area by the cell identification of carrying in the message number.
Step 203.RAN node judges that whether this cell identification number is predefined test cell identification number, if, continue step 204, otherwise, step 205 continued.
The RAN node can link to each other with several base stations, and can there be several wireless areas each base station.RAN number is set at test cell identification number to cell identification to be tested.In embodiment, it is noted that and have only UE to be tested just to insert from the test wireless area.The RAN node can link to each other with several CN nodes, and core net node to be tested is set at test core net node, can set several CN nodes simultaneously and be test CN node.The CN node comprises MSC and SGSN, wherein, and the corresponding CS of MSC territory, the corresponding PS of SGSN territory.
Step 204.RAN node sends to predefined test CN node to initial direct-sending message.After test CN node receives test post, just can carry out functional test.
If cell identification number is a predefined test cell identification number, illustrate that the initial direct-sending message that carries this cell identification number is test subscriber's message, the RAN node can further be judged the link field information that initial direct-sending message carries.There is a parameter " CN domainidentity " the initial direct-sending message the inside, is used to indicate UE to connect with that CN territory.If the link field that initial direct-sending message carries is the CS territory, the RAN node sends to predefined test MSC to test subscriber's message; If the link field that initial direct-sending message carries is the PS territory, the RAN node sends to predefined test SGSN to test subscriber's message.
Step 205.RAN node is searched the CN node according to the IDNNS parameter of carrying in the initial direct-sending message, and this message is sent to the CN node that finds.
If cell identification number is not a predefined test cell identification number, illustrate that the initial direct-sending message that carries this cell identification number is a normal users message, the RAN node is searched the CN node according to the IDNNS parameter of carrying in the initial direct-sending message, finishes the route of the initial non-access layer information of UE.For the system that uses TMSI/P-TMSI, network resource identifier (Network Resource Identity, NRI) information is as the IDNNS parameter; In order to support NAS Node Selection Function (Non-Access StratumNode Selection Function, NNSF), TMSI/P-TMSI is expanded, the 10bit (from bit14 to bit23) in 32 TMSI/P-TMSI signs is distributed to NRI; The corresponding relation of RAN node configuration CN node and NRI.For the system that uses IMSI/IMEI, V value (Value) information as the IDNNS parameter.UE uses following formula to calculate the V value, V=(IMSI/IMEI div 10) mod 1000, and this formula is represented (value of IMSI/IMEI removes 10) mould 1000, the V value is the integer value of 0 to 999 scope; The corresponding relation of RAN node configuration CN node and V value.
Below illustrate concrete application scenarios.Fig. 3 is the network topological diagram of the embodiment of the invention.Common UE is 1 or 2 accesses from the base station.Test UE is 3 accesses from the base station.Mobile switching centre 1, mobile switching centre 2 and mobile switching centre 3 form the mobile switching centre pond.Mobile switching centre 4 is a mobile switching centre to be tested.Radio network controller is set at the test cell identification with the cell identification of base station 3.When receiving the message of base station transmission, radio network controller judges that whether cell identification that this message carries number is test cell identification number, if, this message is sent to mobile switching centre 4, otherwise, according to Iu-Flex mechanism, from the mobile switching centre pond, select a mobile switching centre to provide service for the user.As seen, be used to base station of testing 3 and the mobile switching centre 4 that is used to test and influence the running of normal users business.
Need to prove that in the Iu-Flex technology, CS territory and PS territory are independently.This technical scheme is general for the processing in CS territory and PS territory.If only need carry out functional test to MSC, then set cell identification to be tested and MSC to be tested, test UE sends test subscriber's message of CS territory business; If only need carry out functional test to SGSN, then set cell identification to be tested and SGSN to be tested, test UE sends test subscriber's message of PS territory business; If desired MSC and SGSN are carried out functional verification, then need to set cell identification to be tested, MSC to be tested and SGSN to be tested, test UE sends test subscriber's message of CS territory business or sends test subscriber's message of PS territory business.
