Description
Technical field
The present invention relates to the communications field, the indicating means of radio network controller identifier in a kind of mobile communication system (Radio Network Controller Identity is called for short RNC-ID) analysis mode.
Background technology
The third generation mobile partner plans (3rd Generation partnership project, be called for short 3GPP) at radio network controller (Radio Network Controller, be called for short RNC) and subscriber equipment (User Equipment, abbreviation UE) defined in 25.331 agreements between by RNC and connected (Radio ResourceConnection for there is Radio Resource in each, abbreviation RRC) UE distributes U-RNTI (Radio Network Temporary Identifier of Universal Terrestrial Radio Access Network, Universal Terrestrial Radio AccessNetwork-Radio Network Temporary Identity).U-RNTI comprises 2 parts 32bit altogether, a part is Serving RNC sign (Serving RNC identity is called for short SRNCidentity), takies high 12bit, be used for the RNC in the unique identification Public Land Mobile Nerwork (Public LandMobile Network is called for short PLMN); A part is service RNTI (Serving RNTI is called for short S-RNTI), takies low 20bit, is used for the UE of unique identification RNC.
Simultaneously, RNC can identify (Cell identity) by broadcast cell in cell system message, comprises 2 parts 28bit altogether, and a part is RNC identity, is used for the RNC of unique identification PLMN; A part is used for the sub-district of unique identification RNC.
In the network design in future, may there be very large PLMN, 4096 RNC of surpassing are wherein arranged, 3GPP has expanded the span of RNC-ID in the R7 release protocol for this reason, and from 0 to 4095 expands to 0 to 65535, expands to 16bit from 12bit.
After the RNC-ID expansion, 25.331 the U-RNTI definition does not change in the agreement, but its regulation is if RNC-ID surpasses 4095, and then actual RNC-ID adds that by the 12bitSRNC identity among the U-RNTI the high 4bit of S-RNTI forms, and actual UE sign is made up of the low 16bit of the S-RNTI among the U-RNTI.Having only for UE distributes the RNC of U-RNTI how just to know also be high 12bit or 16bit that RNC-ID takies U-RNTI, and UE has no way of finding out about it from wherein parsing RNC-ID.Similarly, Cell identity definition does not change yet, and has only the RNC of broadcast system message how to know just that from wherein parsing RNC-ID, UE also has no way of finding out about it.
Problem is,
1) UE need parse RNC-ID in following scene from U-RNTI and Cell identity: if UE is in URA-PCH (UTRAN Acceditation Area-paging channel, UTRANRegistration Area-Paging Channel) configuration that state and UE receive enhancing PCH cell from the system message of current area and UE did not preserve enhancing PCH, then UE need parse RNC-ID from U-RNTI, Cell identity from the current area system message parses RNC-ID, if discovery is inequality, then up URA updating message.
2) DRNC is following scene need parse the cell update message or URA updating message that RNC-ID:DRNC receives that UE is up from U-RNTI after, need parse RNC-ID according to the U-RNTI that carries in the message, send up signaling transmission indicating information to this SRNC then, finish the routing function of cell update message or URA updating message.
In realizing process of the present invention, the inventor finds according to 25.331 present agreements, owing to do not know that according to 12bit still be the RNC-ID that 16bit parses U-RNTI and Cell identity,, may cause call drop like this so UE and DRNC can't obtain correct RNC-ID.
