[0003] When the operator's 3G network, not controlling 2G network, concludes an agreement on national roaming services to subscribers outside the coverage area of the operator's 3G network, problems can occur. The roaming partner may also provide 3G services. However, 3G services may not be available for national roaming. Similarly, the network operator, operating in two modes can enable international roaming only 2G networks. Another similar case may occur when access to the 3G network have only individual clients in the home network. Users roaming (usually those who do not have permission to use 3G services) must not use 3G services, when the cell (cell) 3G are in the area of their location. On the other hand, when the information about the neighboring cell 3G broadcast on the 2G network, the user of the roaming services will also receive and use this information. This means that roaming clients have the possibility of re-election of cell 3G. The network operator can ensure that the user is roaming will not get 3G services, focusing cell 3G in the area (s) location, good (-s) from areas of the 2G, and then rejecting requests to update the place which the provisions 3G for those subscribers, who are not allowed to use cell 3G (at an appropriate reason). Thereafter, the subscriber will be forced to leave the cell 3G, but will remain in the same network, when the rejection reason is, for example, #15 (in this area no suitable cells").

[0004] Such a scenario (not related to roaming) may also occur in home networks with support for 2G and 3G, when the user has access only to part 2G home network and does not have access to part of the 3G.

[0005] This means that if the failed registration process location (LR) ends with the rejection by the network, the user equipment (UE) is controlled by the reason code, which includes the rejection message request. In some cases, codes of causes of failure are significant for all cells that are in the same location area (LA). For example, reason code #15 (in this area no suitable cell") prohibits the access of the user equipment to the cells in the same location area. Deviation zone location causes the user equipment to add this area to the list of restricted areas, access to which is denied to the user equipment for a specified period of time (e.g. 12 hours).

[0006] the Subsequent procedure Pereybere cells will exclude all cell service land mobile network is Oh communications networks (PLMN), which indicate the same location area, thus, the network gives the user equipment a command to search a different area locations in the same PLMN.

[0007] One problem in this approach is that when the user equipment switches back to GSM cell, the only known data on neighboring cells WCDMA, based on news reports, are radio frequency and scrambling code. In addition, switching from 2G to 3G is on this principle that the need to test the suitability of the destination cell before making attempts to switch absent. In some cases this is not possible without a compromise on the part of a serving cell.

[0008] This means that the user equipment over a short period of time may try to make previsor on the same or another cell 3G. This pervisor will fail, because the area of the location listed in the list of prohibited zones. However, this information will not be known until such time as the user equipment will not Pereybere the cell or can't read the information about the location area of the cell (for example, before changing cells). This approach requires time, increases energy consumption, and in the worst case, the user can floor the IC on a bad connection, because failure (redundant) connection in packet GPRS (when previsor cell is programmed in the mode NC0 or NC1) is a break in the work. In this case, the data transfer can be significantly degraded (depending on the frequency of "extra" attempts of choice), can be lost page, or may completely lose connection.

[0009] On the side of 2G user equipment connected to SSN, waiting for more information SI3/4 before it will be possible previvor. Information received in the message system information contains data about the areas of the neighboring cells. Therefore, before changing the cell the user equipment can determine whether a cell in the list of prohibited zones. In this case, the user equipment can prevent the switching cells in the cell.

[0010] In the case of interaction between 2G and 3G networks, this approach in most cases is not applicable. Currently the only solution for the user equipment is switching cell according to the principle described above. This mechanism of trial and error is not sufficiently effective. Failure can be repeated continuously, even in the case when the user equipment attempts to produce multiple previsor on one and the same achak the 3G.

[0011] In the case of Pereybere on the 3G cell, the user equipment is required to read the system information of the cell 3G in order to obtain information about the location area this cell. However, in order to perform this task, when there is a current connection GPRS data transmission, the mobile station shall abort the data transfer, which can cause a decrease in throughput.

[0012] it Can be noted that a similar situation also occurs from 2G, when the user equipment or mobile station (MS) connected to RSSN. In this case, the user equipment receives the parameters of neighboring cells(-EC), relating to Pereybere cells from the current batch system information of the 3rd type of a serving cell channel RSCN. This means that to obtain the parameters that affect previsor cell, the mobile station is not required to read the information SI3/4 neighboring cells. Thus, the mobile station does not know LAI adjacent cells, resulting in the same situation as when Pereybere between 2G and 3G cells.

DETAILED DESCRIPTION

[0025] Examples of carrying out the invention generally relate to mobile communication, but also applicable to communication systems that do not use cellular technology. Embodiments of the present invention increase the mobility in situations where the mobile device, also called user equipment, can produce pervisor or change of cells in the zone of the location in which it has no access rights. The invention is described on the example of interaction of the mobile communication systems of the second and third (2G, 3G) generations, but are not limited, and is also very useful for use in UTRAN networks.

[0026] When the user equipment is registered in the cell terrestrial mobile network sharing (PLMN), it can produce previsor cells to ensure their position in the best cell, the corresponding available in the serving PLMN to the network settings.

[0027] If, after Pereybere of a cell based on LAI found a new cell, I is emerging as a part of another zone location the user equipment determines whether to register the location with the aim of informing the network about moving to another location area.

[0028] In accordance with an exemplary embodiment of the present invention the user equipment provides the ability to associate information about the location area information of the neighboring cell based on the list of neighboring cells and broadcast information identifying the membership of a specific cell to the area included in the list of prohibited zones.

[0029] To solve the above problems is provided by various embodiments of the invention, including embodiments of using the network and at least one option that is intended only for the user equipment. Option, used only for the user equipment, in comparison with modern methods provides an improved system. Network embodiments of the invention provide a flexible and efficient solution of the above problems in the long run.

[0030] embodiments of the invention can be carried out by adding to the broadcast system information of certain data linking area location with cells from the list of neighboring cells. It can wypolnjatj the like on the side of 2G, and on the side of the 3G, which is described next.

[0031] Some network embodiments of the invention are as follows. In the example embodiment of the invention in a broadcast message system information radio access network adds additional information to enable management of the user equipment to prevent its connection to the cells of the zone location, is prohibited for the user equipment. In this case, in each cell from the list of neighboring cells 3G received in the broadcast message with system information radio access network 2G, added detailed information about the location area and/or PLMN. Alternatively, this information can be added to the broadcast message system information radio access network 3G that allows user equipment to use this additional information to return in the cell 2G and continue working in it (note that in accordance with conventional practice, the PLMN information is already provided for 3G cell, and information about the location area not included).

[0032] Instead of sending complete information about the location area in the broadcast message system information radio access network, in this embodiment, this information is simplified and indicates Ave is adherence group of cells 3G to the same location area. Thus, if the user equipment can determine the actual location area of one cell of the group, then it can be concluded that other 3G cell of the same group are located in the same area.

[0033] In accordance with the embodiment of the invention in the rejection of the request to update the locations of the reference network also sends to the user equipment the list of prohibited zones. With this information and determining information about the location area of the cell 3G (for example, using one of the above solutions or existing procedures), the user equipment will not attempt to update the location every time you log in the location area not specified in the list of areas prohibited for roaming".

[0034] In accordance with an example embodiment of the invention, intended only for the user equipment, the user equipment stores the information it receives from its environment, and thereby may avoid subsequent re-election of cells to cells of the group that have already been defined as part of the forbidden zone location.

[0035] Option is intended only for the user equipment may be implemented as follows: when the user equipment receives otklonenie the request to update the location with the rejection reason #15, in addition to the LAI in the list of areas prohibited for roaming" (also referred to here as the list of prohibited LAI), which is defined in the document 3GPP TS 24.008, the user equipment prohibits subsequent previsor all 3G cell belonging to the same frequency as the cell for which it was obtained, the deviation of position updates. This can be done by recording certain information about the cell, at least representing a frequency of the cell and its LAI. The result is the creation of a "black list" level RAN for cells or frequencies that is used together with the list of the forbidden LAI so that the user equipment is not produced retry selection of cells with a given frequency, while LAI is prohibited.

[0036] In accordance with an example embodiment of the invention, if the cell with the highest rank is vnutrisutochnoi or megastates cell (as defined in the document 3GPP TS 25.331), which is unsuitable because it is part of the "list of areas prohibited for roaming" or belongs to a PLMN which is not indicated as equivalent to the registered PLMN, the user equipment should not consider this and other cells with the same frequency as possible Pereybere for a period of not more than 300 C. If the cell with the highest rank is used for different technologyradiology and unfit, as it is in the "list of areas prohibited for roaming" or belongs to a PLMN which is not specified as equivalent to the registered PLMN, the user equipment will not consider this cell as a possible variant of Pereybere for a period of not more than 300 C. Here "registered PLMN" is called PLMN in which the registered user equipment. Other PLMN can be recognized by the user equipment equivalent to the registered PLMN, for example, based on the roaming agreement between the operators of the PLMN.

[0037] figure 1 shows an example embodiment of the invention during its implementation only for the user equipment. It should be noted that a logical block diagram in figure 1, as in figure 2, the user equipment is listed as a mobile station (MS).

As shown in step 1A of the user equipment is in a cell with a particular radio access technology. In step 1C, the user equipment performs measurement on the basis of the list of neighbor cells/frequencies received from the radio access network with the current radio access technology. Note that adjacent cells may belong to the same or a different radio access technologies and these measurements shall be made on the basis of broadcast messages to neighboring cells. In step 1C, the enjoyment is defined equipment finds the cell or cell list, satisfying certain radiolarian, as defined in the document 3GPP TS 45.008 and 3GPP TS 25.304. In step 1D of the user equipment selects the cell for Pereybere. The selected cell may belong to the same or a different radio access technologies compared to the current cell.

[0038] After selecting cells for Pereybere determination in step 1E is performed regardless of whether the cell is in a black list cells/frequencies level RAN, the formation of which is described in more detail below. If the selected cell is not in the list, in step 1F determines whether it is suitable. If the selected cell is determined as appropriate, processing continues in step 1I. If the selected cell is not suitable, processing continues at step 1G. If the selected cell has blacklisted cells/frequencies level RAN (step 1E), processing also continues at step 1G. It should be noted that the use of the term "selected cell" does not imply attempts of the user equipment to communicate. On the contrary, the user equipment selects the cell and evaluates the suitability of a cell before attempting to connect to it. Thus, the term "selected cell" does not imply that the user equipment selects or Pereybere cells. Instead, the user equipment vybere and evaluates the suitability of a cell before attempting to connect to it.

[0039] In step 1G determination is made in the case, if possible to select the cells is another cell. If there is another option for selecting, processing continues at step 1D. If there is another option for selecting, processing continues at step 1H, while the user equipment remains in the current cell, and processing proceeds to step 1B.

[0040] In step 1I user equipment in a selected cell and receives from the radio access network a list of neighbor cells/frequencies. In step 1J user equipment starts the process update location in the underlying network. In step 1K network rejects the presence of the user equipment in the area of location/PLMN. In step 1L user equipment stores the identifier (LAI) of the current cell in the list of prohibited LAI in accordance with, for example, document 3GPP TS 24.008, and starts the timer. In step 1M user equipment maintains a black list of level RAN, in which recorded information about the cells obtained in the measurement cell. This information about cells may contain: a) only the frequency of the current cell, b) the frequency and code of the current cell, in) frequency/cell from the list of neighbor cells/frequencies provided by the radio access network, the radio access technology of the current cell. This information is Oia associated with LAI cell from which it is derived. In step 1N the user equipment searches for suitable for connecting cell and continues from step 1A. Cell can belong to different radio access technologies than the cell in which at the moment is the user equipment, and may refer to another PLMN and/or area location.

[0041] the lock cells/frequencies can be specified in different ways. This list provides examples of possible options lock time:

1) Forever,

2) Until the next successful Pereybere cells

3) To receive from the radio access network of a new list of neighboring cells,

4) In accordance with the current definition of the period of validity of the list of prohibited LAI. This means that all cells in a given frequency banned up until LAI is in the list of prohibited LAI. Rules for processing this list (including when it must be clear) are given in the document 3G TS 24.008,

5) Until the next successful update location in the area with the same LAI as in the list of prohibited LAI,

6) Until the next successful update location with any LAI in any radio access network,

7) Until the next successful update location in the radio access network, the equivalent of a radio access network with the LAI, which is not in the list is different LAI.

[0042] after the time lock the list of neighbor cells/frequencies removed.

[0043] figure 2 in accordance with an example embodiment of the invention shown purification technology blacklist level RAN in the user equipment. As shown in the drawing, in step 2A the user equipment is in the cell. If it triggers any of the three triggers (a, b, C), indicating the expiration time of the option clears the list of forbidden LAI, removing a subscriber identity module (SIM) or a power outage, processing continues at step 2B, where the information list of the forbidden LAI deleted.

Then processing continues at step 2C, where the black list level RAN erased.

[0044] If, in accordance with option 1 (opt1), after unsuccessful attempts to register the location (FIRST_CELL_RESEL_AFT_FAILED_LR) is previsor cells, processing also continues at step 2C. If, in accordance with option 2 (opt2), after an unsuccessful registration attempt (NEW_NLIST_RECEIVED_AFT_FAILED_LR) user equipment receives the list of neighbor cells/frequencies, processing also continues at step 2C. If, in accordance with option 3A (opt3a), is the first successful registration location (FIRST_SUCCESSFUL_LR), processing also continues at step 2C.

[0045] If, in accordance with option 3b (opt3b), is the first successful registration conventions at the (FIRST_SUCCESSFUL_LR), processing continues in step 2D. If in step 2D indicator LAI current cell coincides with LAI list of forbidden LAI, processing continues at step 2F, and a black list level RAN cleared. Alternatively, if the LAI of the current cell does not coincide with LAI list of forbidden LAI, processing continues at step 2G, and with a black list level RAN no action was taken.

[0046] In accordance with option 3C (opt3c) is the first successful registration location (FIRST_SUCCESSFUL_LR), and processing continues in step 2E. If in step 2E LAI and radio access technology the same as those that are in the list of prohibited LAI, processing continues at step 2F, and a black list level RAN cleared. Alternatively, if LAI and technology radio access not coincide with those that are in the list of prohibited LAI, processing continues at step 2G, and with a black list level RAN no action was taken.

[0047] the Use of black list level RAN can be done in different ways. One approach prohibits all 3G cell in the list of neighboring cells in 3G, when the user equipment receives the deviation register the location with the rejection reason #15. The same approach can be used in a less strict variant, when the user equipment prohibits only the cell for which the obtained deviation of position updates with the rejection reason #15.

[0048] In accordance with the following description of the lock preferably is used mainly for offline Pereybere cell user equipment and will not, for example, to prevent switching to Smoking frequency.

[0049] In the embodiments described above, optimization of the user equipment it records or stores information, which takes from its environment, and can avoid subsequent re-election of cells to cells from the same groups that were defined as part of the forbidden zone location or PLMN (or who are presumably part of the same zone). The user equipment can memorize the frequency and/or other properties, such as scrambling code, which can be used to re-identify cells previously rejected the registration request location.

[0050] the following example shows how a network solution for a grouping of zones location in accordance with an example embodiment of the invention can be typed using only the simplified location information in the broadcast message system information radio access network 3G. This embodiment can also be used with some modifications fields of the message, if it will be more convenient, including the report in full the information about the location area.

[0051] the system information Block type 18 contains the PLMN-IDs of the neighboring cells, which must be taken into account both in idle mode and in connected mode. Information elements (IE)are underlined and in bold added in accordance with an example embodiment of the invention.

The information element/group NameThe needMultiType and referenceDescription semantics
The PLMN IDs in standby modeopt.The PLMN IDs of the neighboring cells 10.3.7.53a
The PLMN identifiers in the connection modeopt.The PLMN IDs of the neighboring cells
Grouping LA in standby modeopt.Grouping LA neighboring cells HHH
Grouping LA mode connectionopt. Grouping LA neighboring cells HHH

[0052] the Above information elements contain the grouping of areas of the neighboring cells and can be formulated as follows.

[0053] with respect to the two above tables it should be noted that the field "maxCellMeas" is defined in the document 3GPP TS 25.331 and every field LA group" specifies the location area different from the serving cell, which was given a list of IDs of cells. In the above encoding field LA group" is just a number, limited to a specified range. It can also be replaced by the actual information area identification (LAI). If you want actual information LAI, user equipment only needs to obtain information LAI from one of the cells listed under the same field of the LA group.

[0054] For a variant of the invention, in which the required information shall be transmitted in the broadcast message system information radio access network 2G, information about the location area, and perhaps PLMN each adjacent cell 3G can be transmitted in the message system information of a new type, or, alternatively, new fields can be added to currently used by the message such as system information Type 2quater.

[0055] the following not limiting the invention example shows how you can implement the encoding system information by adding a new field in the message system information of an existing type. As before, the information elements (IE)are underlined and in bold added in accordance with an example embodiment of the invention.

[0056] Here, the field LAI_ID_3G can contain full information LAI neighboring elements belonging to the LAI, or simplified information LAI.

[0057] the Field 'Number_of_3G_Neighbour_Cells' is used to specify the number of neighboring elements belonging LAI specified in LAI_ID_3G, and specify a field length '3G_Neighbour_Cell_lndex' or '3G_Neighbour_Cell_bitmap'.

[0058] This embodiment of the invention can be used with the introduction of two network options: "the solution of the broadcast zone location" and "solution with grouping zones location.

[0059] it is Preferable to consider the criteria for removal of a cell from a list of unsuitable cells, such as boundary zones in which other PLMN neighboring regions can use the same radio frequency.

[0060] Network embodiments of the invention are designed to prevent problems, which may occur for legacy user equipment, which should also recognize the modern system information. In contrast to the use of an entirely new encoding of lists of neighboring cells, it may be preferable to transmit a separate list of the areas of the cells, different from those in the list of neighboring elements. The best way this can be done by passing a list of neighboring cells in the current encoding, and then complementing the list, using the same indices for the identification of areas location of each cell or group of cells from a list of neighboring elements. This additional information may be included in the same message, system information, if it has enough space. Otherwise, it can be entered a new message.

[0061] the blacklist level RAN in the user equipment may be composed of custom hardware system without standards, with due consideration to remove the black list, so not to lose the 3G cell, it is possible to Pereybere.
