Description

Method for controlling terminal mobility process and network side equipment

technical field

The invention relates to the field of wireless communication, in particular to the technology of controlling terminal movement.

Background technique

With the development of communication technology, the third generation mobile communication system has appeared in the field of communication: Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, referred to as "UMTS"). The structure of the UMTS system is similar to that of the second-generation mobile communication system, consisting of logical network units. Functionally, these network units can be divided into radio access network (Radio Access Network, referred to as "RAN") and core network (Core Net, referred to as "CN").

The RAN is used to handle all wireless-related functions, and is mainly composed of a base station node and a radio network controller (Radio Network Controller, referred to as "RNC"). The CN is used to handle all voice calls and data connections in the UMTS system, and implement switching and routing with external networks. CN can be further divided into circuit domain and packet domain from the function. The packet domain core network function can be logically divided into two general packet radio service support nodes (GPRS Support Node, referred to as "GSN"): General Packet Radio Service Service Support Node (Serving GPRS Support Node, referred to as "SGSN") and general packet radio service support node Wireless service gateway support node (GPRS Gateway Support Node, referred to as "GGSN"). RAN, CN, and user equipment (User Equipment, referred to as "UE"), that is, terminals, constitute a UMTS system.

In the investment cost of UMTS mobile network, equipment cost and transmission network cost account for the main part, especially the cost of access network equipment (such as RNC and base station nodes) and transmission resources (Iub interface transmission). Today, when operators pay great attention to the cost of network construction, resource sharing becomes an ideal choice for relatively weak operators. Among them, under the premise of sharing (joint investment and operation and maintenance) access network equipment and transmission, each operator owns a license, and each operator monopolizes its own carrier frequency cell, which has become a typical network sharing model. In this mode, the cell is exclusively occupied by the operator, as shown in Figure 1.

According to the 3GPP protocol, a UE in the state of IDLE (idle)/CELL_FACH (cell forward access channel)/CELL_PCH (cell paging channel) needs to be 11 (System Information Block type 11, referred to as " SIB11") system message for cell reselection from the neighbor cell list. For the UE in the URA_PCH (Using the Paging Channel of the Terrestrial Radio Access Network Registration Area of the mobile communication system), it is necessary to perform URA reselection according to the UTRAN Registration Area (UTRAN Registration Area, "URA" for short) list in SIB2. After URA reselection, the Initiates the URA update procedure.

In the CELL_FACH/CELL_PCH/URA_PCH state, the UE will initiate the cell update process after reselecting the cell; the UE in the CELL_DCH (Cell Dedicated Channel) state will perform measurement according to the neighbor cell list in the measurement control message, and report the measurement report to the RNC Execute the handover decision.

The neighbor cell list in SIB11 and the measurement control message is derived from the neighbor relationship configuration, and the URA list in SIB2 is derived from the cell and URA mapping relationship configuration. By controlling the configuration of the adjacent relationship and the configuration of the mapping relationship between the cell and the URA, the SIB11 and SIB2 can be controlled, thereby controlling the mobility process of the UE.

The inventors of the present invention found that, for the RNC in the shared network with independent carrier frequency as shown in Figure 1, according to the agreement reached between the operators sharing the RNC, it may be possible to allow the UE to operate in cells belonging to different operators Mobility behaviors such as inter-cell handover and cell update may also be mobility behaviors such as not allowing the UE to handover between cells belonging to different operators and cell update. If the mobility behavior between different operators is prohibited, then for the RNC, an effective method is needed to meet the operator's requirements. However, no mechanism has been proposed to control UE mobility between different operator networks.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

The first embodiment of the present invention relates to a method for controlling the mobility process of a terminal. In this embodiment, a neighboring cell relationship is established for the terminal according to the set flag, and the handover and/or cell of the terminal is performed according to the neighboring cell relationship Reselection is used to control the mobility process of the terminal, and the specific process is shown in FIG. 2 .

In step 210, the network side establishes a neighbor cell relationship for a terminal that needs to perform handover or cell reselection according to the set flag. Specifically, the network side pre-sets a global flag in the RNC to indicate the permission of the terminal to move between networks of different operators. That is to say, by setting a global flag, it indicates whether a terminal of a specified operator is allowed to move in the networks of one or more other specified operators. The flag can be a variable of Boolean type (for the case of allowing movement in the network of another specified operator), or a set of variables of Boolean type (for allowing mobile in the network of other specified operators) in the case of moving).

For example, a global flag is set for operator A to indicate whether the terminal of operator A is allowed to move in the network of one or more specified operators. Assuming that the terminal of operator A can move in the network of operator B, but not in the network of operator C, then the set global flag can be 01 (the low bit indicates operator C, the high bit indicates operator B, "0 " means allowed, "1" means not allowed).

When a terminal of operator A needs to perform handover or cell reselection, the network side establishes a neighbor cell relationship for the terminal according to the set flag. Specifically, according to the set flag, the network side obtains the set of cells of each operator's network that the terminal is allowed to access, and establishes a neighbor cell relationship among the cells in the obtained set of cells.

For the above case, according to the set flag "01", the network side can know that the terminal is allowed to access the network of operator B, and since the operator to which the terminal belongs is operator A, the terminal is allowed to access the network of operator B. The set of cells is the set of cells of operator A network and operator B network. As shown in FIG. 3 , the shaded cells are the cells that the terminal is allowed to access. If the terminal is currently in cell 1, the adjacent cells of cell 1 include cell 2, cell 3, and cell 4, cell 1 and cell 2 are the network cells of operator A, cell 3 is the network cell of operator B, and cell 4 is the network cell of operator B. Carrier C's network cell. Then, according to the flag, the neighbor cells included in the neighbor cell list established by the network side for the terminal are cell 2 and cell 3, and cell 4 is not included.

It should be noted that a unique public land mobile network identification (PLMN ID) attribute can be set for each cell to identify the operator to which the cell belongs. Therefore, the network side can identify the operator to which the cell belongs according to the PLMN ID of each cell. operator. The PLMN ID set for each cell can be notified to the terminal by broadcasting in the Master Information Block ("MIB" for short) of each cell.

Next, enter step 220, the network side will send the neighbor relationship established for the terminal, that is, the neighbor list established for the terminal, to the terminal. Specifically, if the terminal is in the IDLE/CELL_FACH/CELL_PCH state, that is to say, the terminal needs to perform cell reselection according to the neighbor list, then the network side will carry the neighbor list established for the terminal in SIB11, sent to the terminal. If the terminal is in the CELL_DCH state, that is, the terminal needs to perform cell handover according to the neighbor cell list, the network side will carry the neighbor cell list established for the terminal in the measurement control message and send it to the terminal.

Next, enter step 230, the terminal performs handover or cell reselection according to the received neighbor cell relationship. Specifically, since the network side has already carried the SIB11 or the measurement control message in the neighbor cell list established for the terminal and sent it to the terminal, if the terminal needs to perform cell reselection, the terminal can pass the The measurement of each neighboring cell in the area list, reselect a cell, and initiate the cell update process after reselecting the cell; if the terminal needs to perform cell handover, the terminal performs measurement according to the adjacent cell list in the measurement control message, and reports Measurement report, the RNC executes the handover decision, and the terminal is handed over to the cell judged by the RNC.

It can be seen that in this embodiment, flags are set on the network side to reflect the mobile permission of the terminal between different operator networks, and the processing related to terminal mobility is performed according to the flag, so that the terminal can Initiate the mobility procedure.

It is worth mentioning that when the cell with better signal quality actually measured by the terminal is not in the neighbor cell list sent by the network side, it may ignore the neighbor cell list sent by the network side and directly request a handover from the network side or The cell reselects to this cell. Therefore, if the network side receives a message from a terminal requesting handover or cell reselection to another cell, and the cell is a cell outside the neighbor cell relationship established for the terminal, the network side discards the request message of the terminal to prohibit The terminal is handed over or reselected to the cell. To ensure that the terminal initiates the mobility process according to the requirements of the operator.

The second embodiment of the present invention relates to a method for controlling the mobility process of a terminal. This embodiment is substantially the same as the first embodiment. The difference is that in the first embodiment, the global flag set by the network side indicates whether a The terminal of the specified operator moves in the networks of one or more other specified operators. However, in this embodiment, the global flag set by the network side indicates whether a terminal of a specified operator is allowed to move in the networks of all operators. The flag can be a variable of Boolean type (for example, "0" means allowed, "1" means not allowed).

For example, a global flag is set for operator A to indicate whether the terminal of operator A is allowed to move in the networks of all operators. Assuming that the terminal of operator A can move in the networks of other operators (such as operator B and operator C), then the set global flag is "0". When the terminal of operator A needs to perform handover or cell reselection, the network side can know that the terminal is allowed to access the network of all operators according to the set flag. Therefore, the acquired cell that the terminal is allowed to access The set is the set of cells of all operator networks, as shown in Figure 4, the cells in the shaded part are the cells that the terminal is allowed to access.

The third embodiment of the present invention relates to a method for controlling the mobility process of a terminal. This embodiment is roughly the same as the first embodiment. The difference is that in the first embodiment, the global flag set by the network side indicates whether a The terminal of the specified operator moves in the networks of one or more other specified operators. However, in this embodiment, the global flag set by the network side indicates whether to allow the terminal of any operator to move in the networks of all operators.

That is to say, in the first embodiment, the network side needs to set a global flag for each operator, but in this embodiment, the network side only needs to set a global flag, which can be a Boolean variable, such as "0" indicates that the terminal of any operator is allowed to move in the networks of all operators, and "1" indicates that the terminal of any operator is not allowed to move in the networks of all operators. Therefore, if the flag is set to "0", when any operator's terminal needs to perform handover or cell reselection, the network side obtains the set of cells that the terminal is allowed to access according to the set flag as all operators The cell set of the network; if this flag is set to "1", when any operator's terminal needs to perform handover or cell reselection, the network side obtains the set of cells that the terminal is allowed to access according to the set flag. The cell set of the operator network to which the terminal belongs.

The fourth embodiment of the present invention relates to a method for controlling the mobility process of a terminal. This embodiment is roughly the same as the first embodiment. The difference is that in the first embodiment, the global flag set by the network side indicates whether a The terminal of the specified operator moves in the networks of one or more other specified operators. However, in this embodiment, the global flag set by the network side indicates whether a terminal of a specified operator is allowed to move in a specified area belonging to other operators, and the specified area includes at least one cell.

For example, a global flag is set for operator A to indicate whether the terminal of operator A is allowed to move in a specified area belonging to other operators. As shown in FIG. 5 , it is assumed that a terminal of operator A can move in a designated area of operator B, and the designated area includes cell 1 and cell 2 . Then, when the terminal of operator A needs to perform handover or cell reselection, the network side obtains the set of cells that the terminal is allowed to access according to the set flag, which is the cell of operator A network and the cells of cell 1 and cell 2. Set, that is, the cells in the shaded part in Fig. 5 .

It can be seen that, since the flag can further indicate the permission of the terminal to move between cells of different operator networks, the control of the terminal mobility process by the network side can be further precise to different areas of different operator networks.

The fifth embodiment of the present invention relates to a method for controlling the mobility process of a terminal. This embodiment is substantially the same as the first embodiment. The difference is that in the first embodiment, the global flag set by the network side indicates whether a The terminal of the specified operator moves in the networks of one or more other specified operators. However, in this embodiment, the global flag set by the network side indicates the permission of the terminals of each operator to move between the networks of each operator.

For example, there are three operators A, B, and C. Operators A and B allow each other's terminals to access their own networks, and operators B and C allow each other's terminals to access their own networks. However, operators A and C do not allow the terminal of the other party to access their own network, that is to say, the terminal can move between operators A and B, B and C, but cannot move between A and C. The network side indicates the mobile permission of this terminal by setting a flag, for example, setting a 3-bit flag, when the value is "000", it means that the terminal of any operator can be in the network of any two operators When the value is "001", it means that only operator A and operator B allow each other's terminal to access their own network; when the value is "010", it means that only operator A and operator C allow each other The terminal connected to its own network, and so on, for each mobile permission situation, this flag corresponds to a value. Assume that operator A and operator B allow each other's terminals to access their own network, and operator B and operator C allow each other's terminals to access their own network, but operator A and operator C do not allow When the other party's terminal is connected to its own network, the corresponding value is "101", so the network side needs to set the flag to "101" in advance.

When the terminal needs to perform handover or cell reselection, the network side establishes a neighbor cell relationship for the terminal according to the set flag. For example, if the terminal of operator A is currently in cell 1, and the neighbor cells of cell 1 include cell 2, cell 3, and cell 4, both cell 1 and cell 2 are network cells of operator A, and cell 3 is the network cell of operator B. cell 4 is the network cell of operator C. Then, since the flag indicates that the terminal of operator A can move between the networks of operator A and operator B, but cannot move between the networks of operator A and operator C, the network side is doing this for this When a terminal establishes a neighbor relationship, cell 1 is allowed to establish a neighbor relationship with cell 3, but cell 1 is not allowed to establish a neighbor relationship with cell 4. Therefore, the neighbor relationship established for the terminal includes cell 2 (cell 2 itself is belongs to operator A's network) and cell 3, but does not contain cell 4.

The sixth embodiment of the present invention relates to a method for controlling the mobility process of a terminal. In this embodiment, the network side establishes a paging area for the terminal according to the set flag, and performs paging and paging of the terminal according to the paging area. /or update the location to control the mobility process of the terminal, and the specific process is shown in FIG. 6 .

In step 610, the network side obtains the set of cells of each operator's network that the terminal is allowed to access according to the set flag. Specifically, the network side pre-sets a global flag in the RNC to indicate the permission of the terminal to move between networks of different operators. This flag can indicate whether a designated operator's terminal is allowed to move in the network of one or more other designated operators, which is the same as the flag mentioned in the first embodiment; it can also indicate whether a designated operator's terminal is allowed The terminal moves in the network of all operators, which is the same as the flag mentioned in the second embodiment; or indicates whether the terminal of any operator is allowed to move in the network of all operators, which is the same as the flag mentioned in the third embodiment The mentioned flags are the same; or, it indicates whether a terminal of a specified operator is allowed to move in a designated area belonging to another operator, and the designated area includes at least one cell, that is, the same as the flag mentioned in the fourth embodiment; Alternatively, it indicates that the terminal of each operator is allowed to move between the networks of each operator, that is, it is the same as the flag mentioned in the fifth embodiment. The sign representation manners in various situations have been specifically described in the foregoing implementation manners, and will not be repeated here.

Therefore, the network side can obtain the set of cells of each operator network that the terminal is allowed to access according to the preset global flag.

Next, enter step 620, the network side establishes at least one paging area, and each paging area is composed of at least one cell in the acquired cell set. For example, if the network side learns that the set of cells that the terminal is allowed to access is the set of cells of operator A and operator B according to the preset global flag, then the paging area established for the terminal is operated by operator A and/or The cell of operator B, the paging area cannot include the cell of operator C.

Next, enter step 630, the network side performs paging and/or location update of the terminal according to the paging area established for the terminal. For example, the paging area established by the network side for the terminal consists of cell 1, cell 2, and cell 3. Then, when the terminal is in an idle state and the network side needs to page the terminal, the paging area in cell 1, cell 2, and paging the terminal in cell 3.

It is not difficult to find that in this embodiment, the network side establishes a paging area for the terminal according to the set flag, and performs paging and/or location update of the terminal according to the paging area. It ensures that the terminal can initiate URA update according to the requirements of the operator, and avoids the situation that the terminal cannot be paged by the network side because the terminal is in a cell that is not allowed to access.

The seventh embodiment of the present invention relates to a network-side device, as shown in FIG. 7 , which includes a setting module for setting a flag, which is used to indicate the mobile permission of the terminal between different operator networks; and a processing module , for performing processing related to terminal movement according to the flag set by the setting module. Wherein, the flag set by the setting module indicates whether a terminal of a specified operator is allowed to move in the networks of one or more other specified operators; or, indicates whether a terminal of a specified operator is allowed to move in the networks of all operators; or , indicating whether a terminal of any operator is allowed to move in the networks of all operators; or, indicating whether a terminal of a specified operator is allowed to move in a designated area belonging to other operators, and the designated area includes at least one cell; or, Indicates the permission status of the terminals of each operator to move between the networks of each operator.

The processing module includes the following submodules to perform processing related to terminal movement: the first submodule is used to establish a neighbor relationship for the terminal according to the flag set by the setting module, and perform handover and/or cell switching of the terminal according to the neighbor relationship reselection; and/or, the second submodule, configured to establish a paging area for the terminal according to the flag set by the setting module, and perform paging and/or location update of the terminal according to the paging area.

Among them, the first submodule establishes the neighbor relationship according to the set flag in the following manner: according to the flag, obtains the set of cells of each operator network that the terminal is allowed to access, and establishes the neighbor relationship among the cells in the acquired set of cells . The second submodule establishes a paging area according to the set flag in the following manner: according to the flag, obtains the set of cells of each operator network that the terminal is allowed to access, and establishes at least one paging area, each paging area consists of consists of at least one cell.

Since the terminal performs handover or cell reselection according to the neighbor cell relationship established on the network side, this embodiment ensures that the mobility process initiated by the terminal can meet the operator's requirements. In addition, since the network-side device establishes a paging area for the terminal according to the set flag, the paging and/or location update of the terminal is performed according to the paging area. It ensures that the terminal can initiate URA update according to the requirements of the operator, and avoids the situation that the terminal cannot be paged by the network side because the terminal is in a cell that is not allowed to access.

It should be noted that the modules in this embodiment are all logic modules, and there may be various physical implementations in specific applications.

To sum up, in the embodiments of the present invention, a flag for indicating the allowed status of movement of the terminal between networks of different operators is set on the network side, and processing related to the movement of the terminal is performed according to the flag. Different operators may have different requirements on the mobility of terminals. For example, some operators allow terminals to access the networks of other operators, and some operators prohibit terminals from accessing networks of other operators. In other words, some operators allow the terminal to access the network of some other operators, and some operators prohibit the terminal from accessing the network of some other operators. Therefore, by setting a flag on the network side to reflect the terminal According to the permission status of mobility between different operator networks, the terminal mobility-related processing is performed according to the flag, so that the terminal can initiate a mobility process according to the requirements of the operator.

The processing related to terminal movement performed by the network side includes: establishing a neighboring cell relationship for the terminal according to the set flag, and performing handover and/or cell reselection of the terminal according to the neighboring cell relationship. Since the terminal is based on the neighboring cell established by the network side Therefore, it can ensure that the mobility process initiated by the terminal can meet the operator's requirements.

If the network side receives a message from a terminal requesting handover or cell reselection to another cell, and the cell is a cell outside the neighbor cell relationship established according to the flag, the network side discards the request message of the terminal to prohibit the terminal from switching Or the cell reselects to this cell. It is further ensured that the terminal can initiate a mobility procedure according to the requirements of the operator.

The processing related to terminal movement performed by the network side includes: establishing a paging area for the terminal according to the set flag, and performing paging and/or location update of the terminal according to the paging area.
