Abstract
The invention discloses a method for establishing an integrated mobile broadcast (IMB) cell. The method comprises the following steps that: according to network planning, a radio network controller (RNC) determines whether the cell needing to be established is a frequency division duplexing (FDD) cell and/or an IMB cell; the RNC sends a cell establishment request to a base station (NodeB), wherein the cell establishment request contains uplink and downlink frequency point information; and the NodeB establishes the needed cell according to the cell establishment request. The invention also discloses a system for establishing the IMB cell. Based on the method and the system, the NodeB can judge whether the established cell is the IMB cell or FDD cell and therefore can optimize the allocation of resources according to a cell type.
Description
Technical field

Embodiment
Basic thought of the present invention is: RNC determines the type of the community that needs foundation according to the network planning, and sends to NodeB the community foundation request that includes up-downgoing frequency; The up-downgoing frequency point information that NodeB sets up in request according to community is set up the community needing.
Here, described type WeiFDD community and/or the IMB community that needs the community of foundation.
Below in conjunction with the drawings and specific embodiments, the technical solution of the present invention is further elaborated.
Fig. 1 is the method flow schematic diagram that IMB of the present invention community is set up, and as shown in Figure 1, said method comprising the steps of:
Step 101, RNC determines the cell type that needs foundation according to the network planning, if need to set up FDD community, perform step 102, if need to set up IMB community, performs step 103;
Concrete, in the network planning, conventionally all will set up FDD community, and the situation of integrated mobile broadcast is next to set up IMB community when sending.
Step 102, in the light of actual conditions configures the up-downgoing frequency of FDD community, then performs step 104;
Wherein, the feature of FDD community is on two symmetrical frequency channels of separation, carries out reception and the transmission of up-downgoing data, and the up-downgoing frequency that therefore configures FDD community is different.
Step 103, in the light of actual conditions configures the descending frequency of IMB community, and up frequency is configured to identical with descending frequency, then performs step 104;
Wherein, because the feature of IMB community is to only have down channel, there is no up channel, therefore in practice, only need to configure according to actual conditions the descending frequency of IMB community, then up frequency is configured to identically with descending frequency, in order to embody, configure Shi IMB community.
Step 104, request message is set up in the community that RNC carries up-downgoing frequency to NodeB transmission;
Concrete, the community that RNC sends to NodeB is set up in request message and is comprised: the information such as the ID of cell id, up-downgoing frequency, channel and channel power.
Step 105, NodeB receives community and sets up after request message, and the up-downgoing frequency that community is set up in request message judges, when up-downgoing frequency is different, performs step 106, when up-downgoing frequency is identical, execution step 107;
Concrete, when up-downgoing frequency is different, represent to set up Shi FDD community; When up-downgoing frequency is identical, represent to set up Shi IMB community.
Step 106, the respective handling of carrying out the foundation of FDD community, then performs step 108;
Step 107, the respective handling of carrying out the foundation of IMB community, then performs step 108;
Step 108, NodeB returns to community to RNC and sets up response message.
Further, in the situation that system resource is enough, can according to actual conditions need on a veneer, set up the mixed cell of HeIMB community, FDD community, be specially: configure respectively the up-downgoing frequency of HeIMB community, FDD community, and send respectively corresponding community and set up request message.
Fig. 2 is the system configuration schematic diagram that IMB of the present invention community is set up, and as shown in Figure 2, described system specifically comprises: community is set up initial module 21, message transmission module 22, message-analysis module 23He community and set up module 24, wherein,
Initial module 21 is set up in community, is arranged in RNC, for determine the cell type that needs foundation according to the network planning, and configures corresponding up-downgoing frequency, and configured up-downgoing frequency is sent to message transmission module 22;
Concrete, in the network planning, conventionally all to set up FDD community, and when sending the next IMB of foundation of the situation community of integrated mobile broadcast.The feature of FDD community is on two symmetrical frequency channels of separation, carries out reception and the transmission of up-downgoing data, and the up-downgoing frequency that therefore configures FDD community is different.Therefore the feature of IMB community is to only have down channel, there is no up channel, only need to configure according to actual conditions the descending frequency of IMB community in practice, then up frequency is configured to identical with descending frequency, in order to embody configuration Shi IMB community.
Message transmission module 22, is arranged in RNC, and request message is set up in the community that carries up-downgoing frequency for sending to message-analysis module 23;
Concrete, community is set up in request message and is comprised: the information such as the ID of cell id, up-downgoing frequency, channel and channel power.
Message-analysis module 23, is arranged in NodeB, for receiving community, sets up after request message, and the up-downgoing frequency that community is set up in request message is analyzed, and sends to community to set up module 24 analysis result;
Concrete, community is set up in request message when up-downgoing frequency is different, represents to set up Shi FDD community.When up-downgoing frequency is identical, represent to set up Shi IMB community.
Module 24 is set up in community, is arranged in NodeB, for according to analysis result, sets up HuoIMB community, FDD community, carries out the respective handling of community foundation and returns to community and set up response message and set up initial module 21 to community.
Further, in the situation that system resource is enough, can according to actual conditions need on a veneer, set up the mixed cell of HeIMB community, FDD community, be specially: configure respectively the up-downgoing frequency of HeIMB community, FDD community, and send respectively corresponding community and set up request message.
The above, be only preferred embodiment of the present invention, is not intended to limit protection scope of the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
