Description
Technical field
The present invention relates to the mobile communication technology field, be particularly related to TD SDMA (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) technology, relate in particular to a kind of in the base station method and system of allocating cell frequency.
Background technology
The TD-SCDMA standard that China proposes formally becomes one of global 3G standard.Communications network system based on this standard carries out commercial stage at home at present.
When the TD-SCDMA standard is formulated at first, only consider to support in the sub-district frequency.The user capacity of sub-district is very limited under this scheme, and therefore follow-up introducing multi-frequency-point community is promptly supported a plurality of frequencies in a sub-district, to enlarge residence user content.
For the configuration and the report method of multi-frequency-point community logical resource in base station (Node B), " 2GHzTD-SCDMA digital mobile cellular telecommunication net height speed upstream packet inserts Iub interface specification requirement the 4th part: NBAP signaling message part " the 10th chapter regulation is as follows:
The processing resource (be logical resource) of multi-frequency-point community in Node B continued to continue to use definition in base station application part agreement (NBAP, the NodeB Application Part) agreement, and this definition comprises following content:
1, be a home cell (Local Cell) with the processing resources definition of a multi-frequency-point community in Node B, home cell has local district identification (Local Cel lID);
2, the processing resource (be logical resource) of a frequency in Node B is defined as a frequency processing unit (Frequency Process Module), the frequency processing unit has frequency processing unit sign (Frequency Process Module ID).
Each frequency processing unit belongs to and only belongs to a home cell, and it should be unique that the frequency processing unit is identified in its affiliated home cell, but can have identical frequency processing unit between the different home cell.
The foundation of existing sub-district and reconfiguration course comprise the steps: as shown in Figure 1
Step S101:NodeB is to radio network controller (RNC, Radio Network Controller) sends checking response message or resource status indication (RSI) message, carry the frequency processing unit sign that NodeB supports in this resource status Indication message or the checking response message.
Step S102:RNC issues the sub-district to described NodeB and sets up request message (Cell SetupRequest), and described sub-district is set up and carried all configurable frequency point information in the request message.
Step S103:NodeB selects a frequency point information as main frequency point information from the configurable frequency point information of being received, and sends the sub-district carry described main frequency point information to RNC and set up response message (Cell Setup Response).
Step S104:NodeB sends the resource status Indication message to RNC, carries other frequency point information except that main frequency point information in the described configurable frequency point information in this resource status Indication message.
So far finished the process of setting up of single-frequency point sub-district.Wherein among the step S102, the sub-district is set up in the request message also can only carry a main frequency point information, and then step S103 NodeB sends the sub-district and sets up behind the response message no longer execution in step S104.
After single-frequency point sub-district is set up,, then further carry out following steps if in this sub-district, increase new frequency:
Step S105:NodeB sends resource status Indication message or checking response message to RNC, carries newly-increased frequency processing unit in this resource status Indication message or the checking response message.
Step S106:RNC receives this resource status Indication message or checking response message, obtains as yet the not frequency point information of configuration, supposes to get access to altogether three frequency point information, is called frequency point information A, frequency point information B and frequency point information C; RNC sends the cell re-configuration that carries frequency point information A to NodeB and puts request message (Cell Reconfig Request) then.
Step S107:NodeB is according to frequency point information A allocating cell frequency, and returns cell re-configuration to RNC and put response message.
Step S108:RNC sends the cell re-configuration that carries frequency point information B to NodeB and puts request message.
Step S109:NodeB is according to frequency point information B allocating cell frequency, and returns cell re-configuration to RNC and put response message.
Step S110:RNC sends the cell re-configuration that carries frequency point information C to NodeB and puts request message.
Step S111:NodeB is according to frequency point information C allocating cell frequency, and returns cell re-configuration to RNC and put response message.
From above flow process as can be seen, the foundation of sub-district and reconfiguration course are exactly the process that the frequency point information to the sub-district is configured in fact.Set up response message in the sub-district, cell re-configuration is put in response message, checking response message and the state resource indicator message, all needs to carry frequency point information.
Subdistrict frequency point allocation plan of the prior art has following shortcoming:
One, a piece of news can only carry a frequency point information.Put at a checking response message or cell re-configuration and can only carry a frequency processing unit sign in the request message,, then can only in the sub-district, set up a frequency according to the definition of frequency processing unit sign.Under this restriction, set up process by the sub-district and can only set up single-frequency point sub-district.Set up multi-frequency-point community if desired, then need at first to set up a single-frequency point sub-district, RNC puts the mode of message and indicates NodeB to set up each newly-increased frequency by repeating to send many cell re-configurations then.
Two, can not carry the band limits that frequency is supported in the message.
The domestic frequency range of distributing to TD-SCDMA at present is divided into three sections: A frequency range, B frequency range, F-band require Node B can realize supporting simultaneously the ability of multifrequency point.Only support in present audit and the resource status Indication message to report frequency processing unit sign, and do not support to report the band information of frequency processing unit correspondence.Can cause RNC on handling, to have some efficiency like this.For example, after the Node B that supports multiband reported idle frequency unit, RNC did not know which frequency range it supports, need choose a frequency point information when therefore handling in each frequency range and attempt, and according to present case, needed to repeat 3 ability successes at most.
Above shortcoming has caused the configuration flow of existing multi-frequency-point community more loaded down with trivial details jointly, and holding time is longer, and efficient is not high.
