The technical field to which the invention relates.

[1] the Present invention relates to a method of allocating channels multiple access code division multiple access "CDMA", in particular to methods independent of the allocation of channels multiple access code division multiple access "CDMA" for each active sector.

The level of technology

[2] high-Speed transmission of packet data HRPD" is a standard wireless access technologies (radio), optimized for high-speed transmission of large amounts of data. High-speed packet data HRPD ("HRPD") applies technology multiple access code division multiple access (CDMA) and the technology of transmission of multiplexed time division multiplexing (TDM) to provide data transmission of the mobile station. Accordingly, because of the increased speed and volume data transmission system "HRPD" is able to provide the content (content) with multimedia information in a variety of applications, such as wireless Internet access, information about traffic in real-time, broadcast in real time, movies, games, etc.

[3] To transfer large amounts of data with high speed system "Nx HRPD" transmits packet data PEFC is select more than one channel multiple access code division multiple access "CDMA" (destination frequency) for one mobile station. Namely, for packet data technique using multiple carriers.

The invention

Technical problem

[4] In accordance with the existing technology in the system that transmits packet data using multiple carriers for the active sectors are allocated the same channel multiple access "CDMA" (purpose radio frequency - "FA"). Namely, the channel allocation, multiple access "CDMA" (purpose radio frequency) to all other active sectors in the same way as for the service sector, which currently transmits packet data to a particular mobile station, is problematic due to the inefficiency of the management radio resource.

[5] in Addition, in accordance with the existing technology, when data is transmitted using a dedicated channel multiple access "CDMA" ("FA"), it is impossible to determine which of the multiple channels multiple access "CDMA" ("FA")) should be used for transmission of control messages. However, because the control signals can be considered more important than traffic data, it is necessary to transmit such control signals in a more efficient manner.

Technical solution

[6] the Present invention aims at solving the above problems of the existing technology. In d is the query result the present invention provides a method for efficient allocation of channels multiple access "CDMA" (destination radio frequency - "FA") for each active sector of mobile systems, such as system high-speed packet data HRPD". Among the multiple channels multiple access "CDMA" one channel can be selected and used for the transmission of control signals.

[10] figure 3 shows an example of how independent selection of channels multiple access "CDMA" (destination radio frequency - "FA") for each sector in accordance with the embodiment of the present invention.

Examples of carrying out the invention

[11] One aspect of the present invention is understood the present invention, problems and disadvantages of the existing technology in accordance with the above description and further more detailed consideration. On the basis of this understanding developed features of the present invention.

[12] To overcome the difficulties associated with the existing technology, the crust is ASEE the invention provides a method of allocating channels multiple access "CDMA" (destination radio frequency - destination frequency), which can be used in the mobile communication system performing communications using two or more channels multiple access "CDMA", which includes: independent channel allocation, multiple access "CDMA" (frequency assignment) for each active sector corresponding to a particular mobile station, so that for each active sector was allocated at least one channel of the multiple access "CDMA" (assigned frequency); and transmitting packet data using the selected channel multiple access "CDMA" (assigned frequency).

[13] Various features and aspects of the present invention is better understood using the following description and the accompanying drawings. With reference to the accompanying drawings will be reviewed several embodiments of the present invention.

[14] figure 1 shows a block diagram of an example of the procedure of sending and receiving messages between a mobile station (MS) and base station (BS) in accordance with the present invention.

[15] As shown in figure 1, the base station transmits to the mobile station information related to the total number of assigned frequencies "FA" (or channels multiple access "CDMA"), which can manage services on high-speed data transmission. Here information is the situation, related to the total number of channels multiple access "CDMA" (assigned frequencies "FA"), may be passed through the reports of the parameters of the sector (S11).

[16] the following Table 1 shows an example of a message about the parameters of the sector used in the present invention.

[18] let us Return to Figure 1, if the mobile station moves from idle mode to connected mode, or if in connected mode, the list of active sectors is updated, the mobile station transmits to the base station information associated with the active sectors. Information associated with the active sectors that can be transferred through a message update bearer information (S12).

[19] it Should be noted that the cell can usually be divided into three zones (parts). Active sector can be defined as one or more zones of a single cell or as a combination of one or more zones of two or more different cells. We can say that active sector has the strongest line of communication with the mobile station. These sectors are defined to provide fast cell selection.

[20] When using fast cell selection "FCS", the terminal (mobile station) gives advice on the best cell for packet packet data downlink signals and the network. Determining the best cell can be based not only on the propagation conditions of the radio signal, but also on the available resources (e.g., power and code space for the cells in the active set). Various wireless communication systems differ from each action is sustained fashion the epitome of the fast cell selection and in particular, the fact whether the decision to select a cell to cell for the next packet of data on the downlink to the terminal or the network. For example, in the CDMA2000 1x EV-DO network follows the recommendations of the terminal, while the CDMA2000 1x EV-DV network makes decisions, including taking into account available resources.

[26] As can be seen from Table 3, to specify various parameters that should be applied when assigning traffic channels, uses a lot of fields of different lengths (in bits). Some of these fields will be discussed in the following example (not the only possible). The meaning of some fields that are not described in detail, however, can easily understand assistants normal kvali the paths.

[27] figure 2 shows an example of an active sector with four zones of the three cells in accordance with the exemplary embodiment of the present invention. However, this is only an example, since the number of cells and zones can therefore be changed.

[28] figure 3 shows an example of performing the method of independent selection of channels multiple access "CDMA" (destination radio frequency - "FA") for each sector in accordance with the embodiment of the present invention. Figure 3 shows an example of allocation method three channels multiple access "CDMA" (purpose radio frequency - "FA") for the four active sectors.

[29] In variants of the implementation shown in figure 2 and 3, the active sector associated with the mobile station has a first sector, second sector, the third sector and the fourth sector (i.e. sector 1-4). As shown in Figure 3, the channels multiple access "CDMA" (designated frequency - FA) can be allocated independently for each active sector. Namely, the frequency "FA 1 and FA 2" can be allocated to the sector, "1", while the frequency "FA 2 and FA 3 can be allocated to sector 2". It should be noted that the total number of channels multiple access "CDMA" (assigned frequencies "FA")allocated to each sector may vary. Namely, as shown in Figure 3, for a sector to "1" and "2" can be selected in two kanaleneiland access "CDMA" (two frequencies "FA"), for sector 3 may be allocated a single channel multiple access "CDMA" (single frequency "FA"), and for sector 4 can be allocated three channels multiple access "CDMA" (three frequencies "FA"),

[30] From the viewpoint of channels multiple access "CDMA" (assigned frequency), the frequency "FA 1" is allocated to sectors 1, 3 and 4, the frequency "FA 2" is allocated to sectors 1, 3 and 4, and the frequency "FA 3" is allocated to sectors 2 and 4.

[31] as described above, when the channels multiple access "CDMA" frequency "FA") are allocated independently for each active sector, we first define the total number of channels multiple access "CDMA" frequency "FA"), which can be allocated to all sectors, and the number of channels multiple access "CDMA" frequency "FA"), which shall be allocated based on the channel status or the load of each sector can be determined from just the total number of channels multiple access "CDMA" frequency "FA"). Although the drawings shows an example of a method of continuous allocation of channels multiple access "CDMA" frequency "FA") for one sector, channels multiple access "CDMA" frequency "FA"), such as the frequency "FA 1 and FA 2", can be allocated to one sector in intermittent mode.

[32] as described above, if the channels multiple access "CDMA" frequency "FA") are allocated independently for the each active sector, you need to pass the mobile station information associated with the allocation of channels multiple access "CDMA" frequency "FA"). Such information on the allocation of the frequency "FA", which should be transferred, may contain information associated with all channels multiple access "CDMA" (frequencies "FA"), which may be identified, or information associated with the channel multiple access "CDMA" frequency "FA"), which must be allocated for each sector, or information associated with the sector (sectors), which are assigned to each channel multiple access "CDMA" (the frequency "FA"). This information on the allocation of the frequency "FA" can be transmitted in the message about the purpose of channel traffic.

[33] the following Table 4 shows an example of a message about the purpose of channel traffic.

[35] the Message about assigning traffic channels may contain information on the allocation of active sector for a particular mobile station and information associated with channels multiple access "CDMA" (frequencies "FA, which should be highlighted in this active sector.

[36] In the example shown in Table 4, the NumSectors" means information relating to the current number of active sectors for a particular mobile station. Field NumForwardChannels" means total number of channels multiple access "CDMA" frequency "FA")for all active sectors.

[37] in Addition, the message about assigning traffic channels may contain information associated with each active cell, namely the information associated with the pilot code "PN" and a cover of "DRC" each active sector. In the example shown in Table 4, the information associated with the pilot code "PN", is specified via the "PilotPN", a information, include the Naya coated "DRC", specified using fields "DRCCover".

[38] in Addition, the message about assigning traffic channels may contain information associated with the active sector allocated for each channel multiple access "CDMA" frequency "FA"). Namely, in the example shown in Table 4, the field is assigned to the channel AssignedChannel" refers to a specific channel multiple access "CDMA" (the frequency "FA"). Further, the number of assigned sectors "NumAssignedSectors" corresponds to the number of sectors assigned to a particular channel multiple access "CDMA" frequency "FA"). In addition, in the example of Table 4 field AssignedSectorIndex" indicates the active sector allocated for that specific channel multiple access "CDMA" frequency "FA"), and the "TrafficMACIndex" (index control of access to the environment trafc channel) refers to the index of the mobile station for packet data transmission, for which a dedicated channel multiple access "CDMA" frequency "FA")). Field MACIndex" refers to the index of the access control environment "MAC" for power control feedback with channel multiple access "CDMA" (the frequency "FA")allocated to it.

[39] In the example of Table 4, the message about the purpose of the channel traffic based on specific channels, multiple access "CDMA" frequency "FA") may contain information associated with each active sector, to which is allocated to this specific channel multiple access "CDMA" frequency "FA") (i.e. fields AssignedSectorIndex" ~ "MACIndex" in Table 4), as well as information associated with each and any active sector was allocated to a certain channel multiple access "CDMA" frequency "FA") (i.e. fields AssignedSectorIndex" ~ "MACIndex" in Table 4).

[40] When using the above method, the message about the purpose of the channel traffic contains information related to channel multiple access "CDMA" frequency "FA"), for each and every channel, multiple access "CDMA" frequency "FA") (i.e. fields AssignedChannel" ~ "NumAssignedSectors" in Table 4), and information associated with the active sector, for which a dedicated channel multiple access "CDMA" frequency "FA") (i.e. fields AssignedSectorIndex" ~ "MACIndex" in Table 4).

[41] In the application messages about assigning traffic channels, are shown in Table 4 as follows to formulate a method of channel allocation, multiple access "CDMA" frequency "FA").

[42] first, since there are four sectors for which the assigned frequency "FA," number of sectors "NumSectors" contains the value 4. Since there are 3 radio frequency "FA," number of channels "NumForwardChannels" contains the value 3. Each of the four active sectors contains information active sector having a field pilot code "PN" ("PilotPN) and field coverage "DRC" ("DRCCover").

[43] in Addition, first and foremost includes the field value assigned ka is al "AssignedChannel", corresponding to the frequency "FA 1". Since the frequency "FA 1" produced for sector 1, sector 3 and sector 4", box number assigned sectors "NumAssignedSectors" contains the value 3. Meanwhile included values AssignedSectorIndex" ~ "MACIndex" in accordance with the total number of sectors for which the appointment of the frequency "FA 1". Namely, the field "AssignedSectorIndex" ~ field "MACIndex" is included in a sector to "1", "sector 3 and sector 4".

[44] In addition, the enabled field value assigned to the channel AssignedChannel"corresponding to the frequency "FA 2". Since the frequency "FA 2" produced for sector 1, sector 2 and sector 4", box number assigned sectors "NumAssignedSectors" contains the value 3. Meanwhile, included the value of the field "AssignedSectorIndex" ~ the value of the field "MACIndex" in accordance with the total number of sectors for which produced a frequency "FA 2". Namely, the field "AssignedSectorIndex" ~ field "MACIndex" included in respect of sector 1, sector 2 and sector 4".

[45] Additionally include the value of the field "AssignedChannel"corresponding to the frequency "FA 3". Since the frequency "FA" H. made for sector 2 and sector "4", number of sectors "NumAssignedSectors" contains the value 2. Meanwhile, included the value of the field "AssignedSectorIndex" ~ field "MACIndex" in accordance with the total number of sectors for which PR is raised to a frequency "FA 3". Namely, the field "AssignedSectorIndex" ~ field "MACIndex" included in sector 2 and sector 4".

[46] In accordance with the above message about the purpose of the channel traffic can be expressed in terms of the information related to the sectors allocated for each channel multiple access "CDMA" frequency "FA"), but it can also be expressed in terms of information related to channels multiple access "CDMA" (the frequency "FA")allocated to each sector.

[47] as a result of application of the present invention channels multiple access "CDMA" (assigned frequencies: FA) are allocated independently in accordance with the terms and conditions for each active sector, and thus it becomes possible more efficient use of radio resources.
