Description

Cell residency methods and equipment

technical field

The present invention relates to the field of wireless communication, in particular to the technique of staying in a cell.

Background technique

With the development of communication technology, various service requirements and corresponding networks that can meet the requirements appear. In many cases, the network may only provide its corresponding service requirements, but does not support other common services. Taking the more concerned multimedia broadcast multicast service (Multimedia Broadcast/Multicast Service, "MBMS") as an example, the proposed MBMS Single Frequency Network (MBMS Single Frequency Network, referred to as "MBSFN") is a network that only supports MBMS services. A special kind of network. In this network, only MBMS services are supported, and other point-to-point (Point to Point, "PTP" for short) services are not supported.

Similar to the fact that different networks can support different services, different terminals may have different service support capabilities. For example, a high-version terminal can support rich services provided by a high-version network, such as MBMS services; while a low-version terminal may not be able to support these services provided by a high-version network due to the limitation of service support capabilities. When the terminal does not support the services provided by the network, the terminal cannot obtain normal services even if it resides on the network. In this case, the network may need to limit the camping of such terminals, especially when considering the cell camping balance. Due to the limitation of the MBMS service support capability of the terminals of the low version and the characteristic that the MBSFN network only provides the MBMS service, the MBSFN network needs to restrict the residency of these terminals of the low version.

In addition to the above-mentioned MBSFN network, there are many cells that only provide some special services, and more and more private networks also have the requirement to restrict the residence of some terminals.

However, the inventors of the present invention have found that in the current Universal Mobile Telecommunications System ("UMTS" for short) communication system, there is a method of prohibiting all terminals from camping only for some cells that are prohibited from accessing, such as for Forbidden cells, cells reserved for use by operators, and cells reserved for expansion, there are methods of prohibiting all terminals from camping. However, there is no method of restricting some terminals to reside in the cell according to the actual needs of the cell.

Contents of the invention

The main technical problem to be solved by the embodiments of the present invention is to provide a method and device for camping in a cell, so that the cell can restrict the camping of some terminals on the cell according to requirements.

In order to solve the above technical problems, an embodiment of the present invention provides a cell camping method, including the following steps:

The terminal receives the camping condition or entry prohibition condition from the cell broadcast message;

If the terminal satisfies the camping condition or does not meet the barring condition, the terminal camps on the cell.

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 cell camping method, as shown in FIG. 1 .

In step 110, the cell with the camping restriction includes the camping condition or entry prohibition condition of the cell in its broadcast message and delivers it in the cell.

The residency condition or entry prohibition condition may be the attribute or capability that the terminal that resides or is prohibited from entering the cell needs to have, and may be carried in the root information element or the extended information element of the sub-information element of the cell broadcast message and sent to the terminal . The root cell mentioned here can be the system information block SIB3, SIB4 or other SIB message blocks. In other systems, the root cell refers to the cell on the basic unit transmitted in the broadcast message, and the sub-cell is the root cell. The information element of the next level may be an information element such as "Cell Access Restriction" (cell access restriction).

Specifically, in order to carry the residency condition or entry-forbidden condition in the root cell or sub-cell for delivery, it is necessary to add a Conditional information element, which indicates the attributes or capabilities required by the terminal that is allowed to camp or is prohibited from camping in this cell. For the convenience of description, this information element is called UE attribute indication (terminal attribute identification). This cell can be added in the root cell SIB3, as shown in the shaded part in Table 1; or, added in the root cell SIB4, as shown in the shaded part in Table 2; or, added in the sub cell "Cell Access Restriction", as shown in the shaded part in Table 3.

The attributes mentioned here may include: terminal version information, terminal special authority information, terminal service-related information, or other terminal group attributes, such as terminal status, Discontinuous Reception (Discontinuous Reception, referred to as "DRX") attributes, terminal mobility, wireless signal quality, etc.

The enumeration method can be used in the information element to specify in detail the attributes that the terminal that is allowed or prohibited to camp on the cell needs to have.

The name of the information element can be changed according to the actual network, and the specific content of the residency condition or the prohibition condition included in the information element can also be determined according to the characteristics of the cell, which is not limited in this embodiment. For example, if the cell is an MBSFN network cell that only supports MBMS services, the newly added information element can be called Barred version indication (forbidden version indication) or non-barred version indication (non-barred version indication). The information element contains the version of the radio access technology of the terminal prohibited from camping or the version of the radio access technology of the terminal allowed to camp on.

For another example, if the cell is a private network cell, the newly added information element can be called UEattribute indication (terminal attribute identification). Capability, that is, the capability of the terminal to support the private network.

For another example, if the cell is a cell that only provides some special services, the newly added information element can also be called UE attribute indication (terminal attribute indication). The terminal capability that the terminal needs to have, that is, the terminal needs to have the ability to support the special service provided by the cell.

table 3

In step 120, the terminal reads the broadcast message of the cell, and obtains the residence condition or entry prohibition condition of the cell from the corresponding root cell or sub-cell in the newly added cell, that is, from the newly added Obtain the attributes or capabilities required by the terminal that allows or prohibits camping on the cell from the information element of the cell.

In step 130, the terminal judges whether the cell allows the terminal to camp on the cell according to the acquired attributes or capabilities required by the terminal that is allowed or prohibited to camp on the cell. attribute or ability, or does not meet the attributes or capabilities required to be prohibited from camping in the cell, it indicates that the cell allows the terminal to camp, and enters step 150; otherwise, it indicates that the cell prohibits the terminal from camping, and enters step 140.

For example, the terminal obtains the version of the terminal whose cell residency condition is allowed from the root information element or sub-information element of the broadcast message, then the terminal judges whether the version of the terminal conforms to this version, and if so, it indicates that the The cell allows the terminal to camp, and proceeds to step 150; if not, it indicates that the cell prohibits the terminal to camp, and proceeds to step 140.

In step 140, the terminal determines that it is prohibited from camping on the cell, and selects another cell to camp on.

In step 150, the terminal determines that the terminal is allowed to camp on the cell, and the terminal regards the cell as a normal candidate cell, and camps on the cell according to the prior art.

It should be noted that, in this step, the terminal may also need to read the existing Cell Barred (cell barred) information element, Cell ReservationExtension (cell reservation extension) information element and Cell AccessRestriction information element according to the existing technology. Reserved for operator use (the cell is reserved for the operator to use) information element, to finally determine whether the cell prohibits the terminal from accessing, and judge whether the terminal can use the current cell as a normal candidate according to the information stored on the terminal side district. After it is determined that the cell can be used as a normal candidate cell, the cell is accessed according to the prior art.

It can be seen that in this embodiment, by carrying the camping condition or the prohibition condition in the cell broadcast message and sending it to the terminal, the terminal can determine whether the terminal is allowed to camp in the cell. Only some terminals that meet the entry prohibition condition can reside in the cell, so that the cell can restrict the residence of some terminals according to requirements. And since the purpose can be achieved only by modifying part of the content of the agreement, it is very convenient to realize.

The second embodiment of the present invention also relates to a cell camping method, which is similar to the first embodiment. The difference is that in this embodiment, after the terminal determines that access to the cell is prohibited, it sets the prohibition timer corresponding to the cell. The value of T _barred is set to infinity, and the reception of the broadcast information of the cell is stopped.

Specifically as shown in FIG. 2 , steps 210 , 220 , 230 and step 250 are respectively the same as steps 110 , 120 , 130 and step 150 , and will not be repeated here.

In step 240, the terminal determines that it is prohibited from camping in the cell, sets the value of the barred timer T _barred corresponding to the cell to infinity, and stops receiving broadcast information of the cell. Wherein, the T _barred corresponds to the cell, and is used to instruct the terminal to receive broadcast messages from the cell after the timer expires, as shown in bold in Table 3. Since the attributes and capabilities of the terminal are static and will not change over time, and the service provision capability of the cell is also fixed, it is determined that the terminal does not meet the attributes or capabilities of resident, or satisfies the prohibition of resident After the attributes or capabilities of the cell are set, there is no need to receive broadcast messages from the cell. By setting the value of the T _barred timer to the maximum, unnecessary receiving, parsing and judging by the terminal can be avoided, and energy consumption of the terminal can be saved. At the same time, the terminal selects another cell to camp on.

The third embodiment of the present invention also relates to a cell camping method, which is similar to the first or second embodiment, the difference is that in the first or second embodiment, a new An independent information element is added, which carries the attributes or capabilities required by the terminal that is allowed or prohibited to camp in the cell. The terminal can judge whether to allow camping only based on the content of the information element and the attributes or capabilities of the terminal; In the embodiment, add a cause value information element in Cell access restriction sub-information element, this cause value information element is used to carry the reason (equivalent to residency condition or barring condition) that the cell limits to stay in, this information element is added After the information element Cell Barred indicating the forbidden cell information or the information element CellReservation Extension indicating the reserved cell information, as shown in the shaded part of Table 4 or Table 5, after receiving the broadcast message of the cell, the terminal needs to read the information first. Cell Barred or Cell Reservation Extension, when the value of Cell Barred or Cell Reservation Extension is "reserved", further read "prohibited" or "reserved" Cause value, according to the cause value, it is judged whether the terminal is allowed to camp in the cell.

Table 4

table 5

The following takes an MBSFN cell as an example for specific description, as shown in FIG. 3 .

In step 310, the MBSFN community sets the value of the Cell Barred information element in the broadcast message to "forbidden", sets the cause value of the Cell Barred information element to "the community only provides MBMS services", and broadcasts the set broadcast message in the community issued in the middle.

In step 320, after the terminal searches for the MBSFN cell, it reads the CellBarred information element in its broadcast message, and if the value of the information element is "forbidden", then enters step 330; otherwise, if the value of the information element is " If not forbidden", go to step 340.

In step 330, the terminal further reads the cause value of the Cell Barred information element, and judges whether the terminal is allowed to access the cell according to the cause value. Since the cause value is "the cell only provides MBMS services", the terminal judges whether the terminal has the ability to receive MBMS services. It is forbidden to camp on this cell, and go to step 350 .

In step 340, the terminal determines that the terminal is allowed to camp on the cell, and the terminal regards the cell as a normal candidate cell, and camps on the cell according to the prior art.

It should be noted that, in this step, the terminal may also need to judge whether it can use the current cell as a normal candidate cell according to the information stored on the terminal side.

In step 350, the terminal determines that it is prohibited from camping in the cell, sets the value of the barred timer T _barred corresponding to the cell to infinity, and stops receiving broadcast information of the cell. Wherein, the T _barred corresponds to the cell, and is used to instruct the terminal to receive the broadcast message from the cell after the timer expires. Since the attributes and capabilities of the terminal are static and will not change over time, and the service provision capability of the cell is also fixed, after the terminal determines that it cannot support the service of the cell, it does not need to receive the broadcast of the cell information. By setting the value of the T _barred timer to the maximum, unnecessary receiving, parsing and judging by the terminal can be avoided, and energy consumption of the terminal can be saved. At the same time, the terminal camps on other cells.

In this embodiment, the MBSFN cell can also set the value of the Cell ReservationExtension information element in the broadcast message to "reserve", set the extension cause value of the Cell Reservation Extension information element to "the cell only provides MBMS services", and set the The broadcast message is delivered in the cell. The terminal judges whether to allow camping in the cell according to the Cell Reservation Extension information element and the cause value. The specific way of judging and the operation after judging are similar to steps 320 to 350 .

The fourth embodiment of the present invention also relates to a cell camping method, which is similar to the first or second embodiment, the difference is that in the first or second embodiment, a new An independent information element is added to carry the required attributes or capabilities of the terminal that is allowed or prohibited to camp in the cell. The terminal can judge whether to allow camping only based on the required attributes or capabilities and the actual attributes or capabilities of the terminal; In this embodiment, an independent information element is also added in the root information element or sub-information element, but the information element carries the network type or network capability, and the terminal can judge Whether the terminal supports the network, if it supports it, it means that it is allowed to camp in the cell, and if it does not support it, it means it is prohibited to camp in the cell. The operations after the judgment are the same as those in the first or second embodiment, and will not be repeated here.

The above-mentioned root information element can be SIB3 or SIB4, and the newly added information element can be called Cell class or cell capindication (cell group or cell capability indication), which carries the network type or network capability to which the cell belongs. Cells can be added at any position in SIB3 or SIB4, as shown in the shaded parts in Table 6 (corresponding to SIB3) and Table 7 (corresponding to SIB4). Similarly, this cell can also be added in the sub-cell Cell access restriction, as shown in the shaded part in Table 8.

Table 8

The fifth embodiment of the present invention also relates to a cell camping method, similar to the first or second embodiment, the difference is that in the first or second embodiment, the terminal broadcasts the root information element or In the information element added in the sub-cell, obtain the residency condition or forbidden condition of the cell, that is, allow or prohibit the attributes or capabilities that the terminal that resides in the cell needs to have; and in this embodiment, by extending the Cell accessrestriction message The existing Cell Barred information element in the cell carries the residency condition or entry prohibition condition of the cell.

Specifically, the enumeration value of the cell Cell Barred contained in the existing Cell access restriction cell has only two kinds of "barred" (forbidden) and "non-barred" (non-forbidden). A feasible extension method is: expand the enumeration value according to new service requirements, and use the residence condition or entry prohibition condition of the cell as the enumeration value of the cell. The extended enumeration value can be multiple, corresponding to different camping conditions or forbidden conditions, which can include the capabilities or attributes of terminals that are forbidden to camp in the cell, the reason for the cell’s forbidden entry, network type or network capability, etc., as shown in Table 9 in bold.

The network side can set the value of the Cell Barred information element in the Cell access restriction information element of the broadcast message of the cell as the corresponding residence condition or entry prohibition condition, and the terminal judges whether the terminal is allowed to access according to the value of the Cell Barred information element. into the area. The operations after the judgment are the same as those in the first or second embodiment, and will not be repeated here.

The sixth embodiment of the present invention also relates to a method for residing in a cell, similar to the first or second embodiment, the difference is that in this embodiment, the CellReservation Extension information element of the Cell access restriction information element in the protocol The meaning of the value is extended, and the meaning of its "reserved" (reserved) value is extended to a fixed residence condition or entry prohibition condition, as shown in the bold part in Table 11. For example, the definition: when the value of the Cell Reservation Extension IE is "reserved", it means that the cell prohibits the access of terminals without MBMS service capability, or only allows the access of terminals with MBMS service capability in this cell. Therefore, during implementation, the MBSFN cell can directly set the value of the Cell ReservationExtension information element of the broadcast message to "reserved", and send the broadcast message in the cell. If the value is "reserved", it means that the cell prohibits the access of terminals without MBMS service capability, or the cell only allows the access of terminals with MBMS service capability, and the terminal determines whether it supports MBMS service or not. Whether the terminal is allowed to camp in the cell. The operations after the judgment are the same as those in the first or second embodiment, and will not be repeated here. Of course, when the value of the Cell Reservation Extension cell is "Reserved", the residency condition or access prohibition condition needs to be defined in the protocol in advance.

Compared with the above several embodiments, this embodiment has the least amount of modification to the protocol, and can best integrate with the existing technology.

Table 11

The seventh embodiment of the present invention is similar to the fifth embodiment, the difference is that in the fifth embodiment, the existing Cell Barred information element in the Cell access restriction information element is extended to carry the residence condition or barred information element of the cell. However, in this embodiment, the existing Cell Reservation Extension information element in the Cell access restriction information element is extended to carry the residence condition or entry prohibition condition of the cell.

Specifically, the enumeration value of the cell Cell ReservationExtension contained in the existing Cell access restriction cell has only two kinds of "Reserved" (reserved) and "not Reserved" (non-reserved), and one is feasible in this embodiment The expansion method is as follows: expand the enumeration value according to the new service requirements, and use the residence condition or entry prohibition condition of the cell as the enumeration value of the cell. The extended enumeration value can be multiple, corresponding to different camping conditions or forbidden conditions, which can include the capabilities or attributes of terminals that are forbidden to camp in the cell, the reason for the cell’s forbidden entry, network type or network capability, etc., as shown in Table 12 in bold.

The network side can set the value of the CellReservation Extension information element in the Cell access restriction information element of the broadcast message of the cell as the corresponding residence condition or entry prohibition condition, and the terminal judges whether the terminal is allowed according to the value of the Cell Reservation Extension information element access the area. The operation after the judgment is the same as that of the fifth embodiment, and will not be repeated here.

Alternatively, in this embodiment, another cell reservation extension information element may be extended in the Cell access restriction information element, which is called the Cell Reservation Extension indication information element. In addition to the original " In addition to the "reserved" and "non-reserved" values, one or more different residency conditions or no-entry conditions are included, as indicated by the shaded areas in Table 13.
