DESCRIPTION OF EMBODIMENTS The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the 0 present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. FIG. 1 is a flowchart of a method for activating or deactivating a carrier according to a first 5 embodiment of the present invention. As shown in FIG. 1, the executor of this embodiment of the present invention is a base station, and the method for activating or deactivating a carrier according to this embodiment of the present invention includes: S101: The base station determines to activate or deactivate at least one secondary carrier used to communicate with a user equipment. 0 S 102: the base station transmits a High Speed Shared Control Channel HS-SCCH order to the user equipment, where the HS-SCCH order carries indication information, the indication information includes at least three bits, the first bit is 0, and the indication information is used to indicate activation or deactivation of the at least one secondary carrier. The base station may configure two downlink carriers for the user equipment (User Equipment, 25 UE for short). When a service of the UE has a lower bandwidth requirement, the base station may deactivate at least one secondary carrier, and when the service of the UE has a higher bandwidth requirement, the base station may activate at least one secondary carrier. When the base station determines to activate or deactivate the at least one secondary carrier used to communicate with the UE, the base station transmits the High Speed Shared Control 30 Channel HS-SCCH order to the UE, where the HS-SCCH order carries the indication information, the indication information includes at least three bits, the first bit is 0, and the indication information is used to indicate activation or deactivation of the at least one secondary carrier. The at 9 least one secondary carrier may generally include at least one secondary uplink carrier or at least one secondary downlink carrier; and if at least two secondary carriers exist, the at least two secondary carriers include at least one secondary uplink carrier and at least one secondary downlink carrier. 5 After receiving an HS-SCCH order transmitted by a base station of the R9 version, a user equipment of the R10 version or the R11 version updates an activation or deactivation state of a corresponding carrier according to values of order bits Xord,1, Xord,2, and Xord,3 that are carried by the HS-SCCH order. Xord,1 is the first bit representing a reserved bit; Xord,2 and Xord,3 indicate activation or deactivation of a secondary uplink carrier (Secondary uplink frequency) and a secondary 0 downlink carrier (Secondary serving HS-DSCH cell); the first bit Xord,1 serving as the reserved bit is set to 0; Xord,2 may correspond to the secondary uplink carrier, and Xord,3 may correspond to the secondary downlink carrier; values of Xord,2 and Xord,3 may be 0 and may also be 1; a bit corresponding to Xord,2 or Xord,3 is 1, which indicates activation of the secondary carrier; the bit corresponding to Xord,2 or Xord,3 is 0, which indicates deactivation of the secondary carrier; in 5 addition, Xord,2, Xord,3 = "10" is a combination not in use. In a specific embodiment, when a base station of the R9 version transmits an HS-SCCH order to a UE of the R10 or R11 version, the HS-SCCH order may be Xord,1 = 0, Xord,2 = 1, and Xord,3 = 1, that is, Xord,1, Xord,2, Xord,3 = "011". When the UE of the R10 or R11 version receives the HS-SCCH order, the UE implements activation of a secondary downlink carrier and activation of a secondary 0 uplink carrier and performs a correct operation according to the order, as expected by the base station of the R9 version. When the HS-SCCH order is xord,1 = 0, xord,2 = 0, and xord,3 = 1, that is, xord,1, xord,2, xord,3 = "001", and the UE of the R10 or R11 version receives the HS-SCCH order, the UE implements activation of a secondary downlink carrier and performs a correct operation according to the order, as expected by the base station of the R9 version. 25 A person skilled in the art may understand that the R9 version and the R10 or R11 version is specifically a release 9 (Release 9) protocol, a release 10 (Release 10) protocol, or a release 11 (Release 11) protocol of the 3rd generation partnership project (the 3rd Generation Partnership Project, 3GPP for short) wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA for short). 30 The base station in this embodiment of the present invention determines to activate or deactivate at least one secondary carrier used to communicate with a user equipment, the base station transmits a High Speed Shared Control Channel HS-SCCH order to the user equipment, where the HS-SCCH order carries indication information, the indication information includes at least three bits, the first bit is 0, and the indication information is used to indicate activation or 10 deactivation of the at least one secondary carrier. After receiving the HS-SCCH order, the UE performs a corresponding operation according to the order. In this way, the UE is capable of performing a correct activation or deactivation operation when a version of the UE is inconsistent with a version of the base station serving the UE, so that the UE performs correct explanation and 5 processing according to the HS-SCCH order, thereby performing normal uplink and downlink communication. The following uses a specific embodiment as an example to describe the present invention in detail. In a specific implementation process, when a base station determines to activate or deactivate 0 at least one secondary carrier used to communicate with a UE, the base station transmits a High Speed Shared Channel HS-SCCH order to the UE, where the HS-SCCH order carries indication information that may indicate activation or deactivation of the at least one secondary carrier. Specifically, a format of the HS-SCCH order is formed by an order type and an order bit, as listed in Table 1. When the base station is of the R9 version, three order bits (order bits) corresponding to the 5 order type (order type) "001" of the HS-SCCH order are xord,1, xord,2, and xor,3. The indication message carried in the HS-SCCH order may be values of xord,1, xord,2, and xord,3. As can be seen from Table 1, when an order mapping value of the three order bits (order bits) xord,1, xord,2, and xord,3 that correspond to "001" is "001", it indicates a function of activation of a secondary downlink carrier; when the order mapping value of the three order bits (order bits) xord,1, xord,2, and xord,3 that 0 correspond to "001" is "011", it indicates functions of activation of a secondary downlink carrier and activation of a secondary uplink carrier. Table 1 Order Type Order Mapping (Order (order type) Mapping) Functionality (Functionality) Xodt,1, Xodt,2, Xodt,3 Xord,1 Xord,2 Xord,3 0 x 1 Activation of a secondary downlink carrier 001 0 x 0 Deactivation of a secondary downlink carrier 0 1 x Activation of a secondary uplink carrier 0 0 x Deactivation of a secondary uplink carrier In the 3GPP R10 or R11 version, a format of an HS-SCCH order for activating or deactivating 25 multiple downlink and uplink carriers is further designed for features of 4 Carrier-High Speed 11 Downlink Packet Access (4 Carrier-High Speed Downlink Packet Access, 4C-HSDPA for short) and High Speed Uplink Packet Access (Dual Cell-high speed uplink packet access, DC-HSUPA for short), as shown in Table 2. Different from the dual-carrier activation or deactivation signaling in the R9 version, one HS-SCCH order combination is used to indicate each allowed combination of 5 activation or deactivation states of uplink and downlink carriers, each HS-SCCH order combination is indicated by different values of 6 bits in order type and order bit fields in the combination, and conversion between combinations of activation or deactivation states of secondary uplink and downlink carriers is implemented by using different HS-SCCH order combinations. A indicates carrier activation (Activate), D indicates carrier deactivation (De-activate), a reserved value 0 indicates a combination not in use at present and does not represent other meanings. Table 2 Order Type Order Mapping Functionality (Functionality) (order type) (Order Mapping) A=Activate; D=Deactivate 1st 2nd 3rd Secondary secondary secondary secondary uplink Xodt,1,Xodt,2,Xodt,3 Xord1 Xord,2 Xord,3 downlink downlink downlink carrier carrier carrier carrier 0 0 0 D D D D 0 0 1 A D D D 0 1 1 A D D A 0 1 0 D A D D 001 1 0 0 A A D D 1 0 1 A A D A 1 1 0 D D A D 1 1 1 A D A D 0 0 0 A D A A 0 0 1 D A A D 0 1 0 A A A D 010 0 1 1 A A A A 1 0 0 Reserved 1 0 1 Reserved 1 1 0 Reserved 12 1 1 1 Reserved Refer to Table 1 and Table 2, when Xord,1 = 0, in Table 1, Xord,1, Xord,2, Xord,3 "000", '001", and "011" indicate deactivation of secondary uplink and downlink carriers, activation of a secondary downlink carrier and deactivation of a secondary uplink carrier, and activation of secondary uplink 5 and downlink carriers, respectively. As can be seen from Table 1 and Table 2, the HS-SCCH order defined in the R9 version uses a bit value to indicate an activation or deactivation state of a carrier, whereas the HS-SCCH order defined in the R10 version uses a bit combination to indicate activation or deactivation states of all secondary carriers, and the bit combination is a combination of an order type and an order mapping. In addition, the secondary downlink carrier in Table 1 is 0 equivalent to the 1" secondary downlink carrier in Table 2. A base station of the R9 version transmits an HS-SCCH order to a UE of the R10 or R11 version following the illustration in Table 1, and after receiving the HS-SCCH order, the UE of the R10 or R11 version updates an activation or deactivation state of the 1" secondary downlink carrier and/or the secondary uplink carrier according to the HS-SCCH order and Table 2. Because the 5 secondary downlink carrier in the R9 version is equivalent to the 1" secondary downlink carrier in the R10 or R11 version, as can be seen from Table 1 and Table 2, when the first bit Xord,1 in the R9 version is 0, the UE of the R10 or R11 version performs a carrier update according to Xord,1, Xord,2, Xord,3 = "000", "001", and "011", and the result of the update is the same as an expectation of the base station of the R9 version on activation or deactivation of a secondary uplink carrier and a 0 secondary downlink carrier of the UE. When the first bit Xord,1 in the R9 version is 1, the UE of the R10 or R11 version performs a carrier update according to Xord,1, Xord,2, Xord,3 = "100", "101", and "111", which is different from the expectation of the base station of the R9 version on activation or deactivation of a secondary uplink carrier and a secondary downlink carrier. In this embodiment of the present invention, a base station transmits a High Speed Shared Control 25 Channel HS-SCCH order to a user equipment, where the HS-SCCH order carries indication information, the indication information includes at least three bits, the first bit is 0, and the indication message is used to indicate activation or deactivation of the at least one secondary carrier; after receiving the HS-SCCH order, the UE performs a corresponding operation according to the order. In this way, the UE is capable of performing a correct activation or deactivation operation 30 when a version of the UE is inconsistent with a version of the base station serving the UE, so that the UE performs correct explanation and processing according to the HS-SCCH order, thereby performing normal uplink and downlink communication. FIG. 2 is a flowchart of a method for activating or deactivating a carrier according to a second 13 embodiment of the present invention. As shown in FIG. 2, the executor of this embodiment of the present invention is a user equipment, and the method for activating or deactivating a carrier according to this embodiment of the present invention includes: S201: A user equipment receives a High Speed Shared Control Channel HS-SCCH order 5 transmitted by a base station, where the HS-SCCH order carries indication information, the indication information includes at least three bits, the first bit is 0, and the indication information is used to indicate activation or deactivation of at least one secondary carrier for communication between the user equipment and the base station. S202: the user equipment updates an activation or deactivation state of the at least one 0 secondary carrier according to the indication information. When the base station determines to activate or deactivate the at least one secondary carrier used to communicate with the UE, the base station transmits the High Speed Shared Channel HS-SCCH order to the UE, where the HS-SCCH order carries the indication information, the indication information includes at least three bits, the first bit is 0, and the indication information is 5 used to indicate activation or deactivation of the at least one secondary carrier. After receiving the HS-SCCH order transmitted by the base station, a user equipment of the R10 version or the R 11 version updates an activation or deactivation state of a corresponding carrier according to values of Xord,1, Xord,2, and Xord,3 that are carried in the indication information in the HS-SCCH order. Xord,1 is the first bit representing a reserved bit; Xord,2 and Xord,3 indicate activation 0 or deactivation of a secondary uplink carrier (Secondary uplink frequency) and a secondary downlink carrier (Secondary serving HS-DSCH cell); the first bit Xord,1 serving as the reserved bit is set to 0; Xord,2 may correspond to the secondary uplink carrier, and Xord,3 may correspond to the secondary downlink carrier; values of Xord,2 and Xord,3 may be 0 and may also be 1; a bit corresponding to Xord,2 or Xord,3 is 1, which indicates activation of the secondary carrier; the bit 25 corresponding to Xord,2 or Xord,3 is 0, which indicates deactivation of the secondary carrier; in addition, Xord,2, Xor,3 = "10" is a combination not in use. In a specific embodiment, when a base station of the R9 version transmits an HS-SCCH order to a UE of the R10 or R11 version, the HS-SCCH order may be Xord,1 = 0, Xord,2= 1, and Xord,3= 1, that is, Xord, Xord,2, Xord,3 = "011". When the UE of the R10 or R11 version receives the HS-SCCH 30 order, the UE implements activation of a secondary downlink carrier and activation of a secondary uplink carrier and performs a correct operation according to the order, as expected by the base station of the R9 version. When the HS-SCCH order is xord,1 = 0, xord,2 = 0, and xord,3 = 1, that is, xord, xord,2, xord,3 "001", and the UE of the R10 or R11 version receives the HS-SCCH order, the UE implements 14 activation of a secondary downlink carrier and performs a correct operation according to the order, as expected by the base station of the R9 version. In this embodiment of the present invention, a user equipment receives a High Speed Shared Control Channel HS-SCCH order transmitted by a base station, where the HS-SCCH order carries 5 indication information; the user equipment updates an activation or deactivation state of at least one secondary carrier according to the indication information. In this way, the UE is capable of performing a correct activation or deactivation operation when a version of the UE is inconsistent with a version of the base station serving the UE, so that the UE performs correct explanation and processing according to the HS-SCCH order, thereby performing normal uplink and downlink 0 communication. The following uses a specific embodiment as an example to describe the present invention in detail. In the R9 version, the first bit xord,1 serving as the reserved bit is set to 0; xord,2 may correspond to the secondary uplink carrier, and xord,3 may correspond to the secondary downlink carrier; values 5 of xord,2 and xord,3 may be 0 and may also be 1; a bit corresponding to xord,2 or xord,3 is 1, which indicates activation of the secondary carrier; and the bit corresponding to xord,2 or xord,3 is 0, which indicates deactivation of the secondary carrier. The secondary downlink carrier in the R9 version is equivalent to the 1" secondary downlink carrier in the R10 or R11 version, a base station of the R9 version transmits an HS-SCCH order to a UE of the R10 or R11 version according to Table 1, and 0 the UE of the R10 or R11 version receives the HS-SCCH order and updates an activation or deactivation state of the 1" secondary downlink carrier and/or the secondary uplink carrier according to the HS-SCCH order and Table 2. As can be seen from Table 1 and Table 2, when the first bit xord,1 in the R9 version is 0, the UE of the R10 or R11 version performs a carrier update according to xord,1, xord,2, xord,3 = "000", "001", and "011", and the result of the update is the same as 25 an expectation of the base station of the R9 version on activation or deactivation of a secondary uplink carrier and a secondary downlink carrier of the UE. When the first bit xord,1 in the R9 version is 1, the UE of the R10 or R11 version performs a carrier update according to xord,1, xord,2, xord,3 "100", "101", and "111", which is different from the expectation of the base station of the R9 version on activation or deactivation of a secondary uplink carrier and a secondary downlink carrier 30 of the UE. In this embodiment of the present invention, a user equipment receives a High Speed Shared Control Channel HS-SCCH order transmitted by a base station, where the HS-SCCH order carries indication information; the user equipment updates an activation or deactivation state of at least one secondary carrier according to the indication information. In this way, the UE is capable of 15 performing a correct activation or deactivation operation when a version of the UE is inconsistent with a version of the base station serving the UE, so that the UE performs correct explanation and performs correct processing on a secondary uplink carrier and a secondary downlink carrier according to the HS-SCCH order, thereby performing normal uplink and downlink communication. 5 FIG. 3 is a flowchart of a method for activating or deactivating a carrier according to a third embodiment of the present invention. As shown in FIG. 3, the executor of this embodiment of the present invention is a user equipment, and the method for activating or deactivating a carrier according to this embodiment of the present invention includes: S301: The user equipment receives a High Speed Shared Control Channel HS-SCCH order 0 transmitted by a base station, where the HS-SCCH order carries indication information, the indication information includes at least three bits, and the indication information is used to indicate activation or deactivation of at least one secondary carrier for communication between the user equipment and the base station. S302: The user equipment determines the first bit among the at least three bits as 0 and updates 5 an activation or deactivation state of the at least one secondary carrier according to the at least three bits. The base station configures two downlink carriers for the user equipment (User Equipment, UE for short). When a service of the UE has a lower bandwidth requirement, the base station may deactivate at least one secondary carrier, and when the service of the UE has a higher bandwidth 0 requirement, the base station may activate at least one secondary carrier. When the base station determines to activate or deactivate the at least one secondary carrier used to communicate with the UE, the base station transmits the High Speed Shared Channel HS-SCCH order to the UE, and the UE receives the HS-SCCH order, where the HS-SCCH order carries the indication information, the indication information includes at least three bits, and the 25 indication information is used to indicate activation or deactivation of the at least one secondary carrier. A value of the first bit xord,1 may be 0 and may also be 1. Because the value of the first bit xord,1 received by the UE may be 0 and may also be 1, the UE determines the first bit among the at least three bits as 0 and updates the activation or deactivation state of the at least one secondary carrier according to the three bits, so that the UE is capable of 30 performing a correct activation or deactivation operation when a version of the UE is inconsistent with a version of the base station serving the UE. In this embodiment of the present invention, a user equipment receives a High Speed Shared Control Channel HS-SCCH order transmitted by a base station, where the HS-SCCH order carries indication information, and the indication information includes at least three bits; the user 16 equipment determines the first bit among the at least three bits as 0 and updates an activation or deactivation state of at least one secondary carrier according to the at least three bits. In this way, the UE is capable of performing a correct activation or deactivation operation when a version of the UE is inconsistent with a version of the base station serving the UE, so that the UE performs correct 5 explanation and processing according to the HS-SCCH order, thereby performing normal uplink and downlink communication. The following uses a specific embodiment as an example to describe the present invention in detail. In a specific implementation process, when a base station determines to activate or deactivate at least one secondary carrier used to communicate with a UE, the base station transmits a High 0 Speed Shared Channel HS-SCCH order to the UE, and the UE receives the HS-SCCH order, where the HS-SCCH order carries indication information that may indicate activation or deactivation of the at least one secondary carrier. When the base station is of the R9 version, xord,2 and xord,3 among three order bits (order bits) corresponding to the order type order type "001" in the HS-SCCH order indicate activate or deactivation of a secondary uplink carrier (Secondary uplink frequency) and a 5 secondary downlink carrier (Secondary serving HS-DSCH cell), and xorl is a reserved bit. The indication message carried in the HS-SCCH order may be values of xord,1, xord,2, and xord,3, where the value of the first bit xord,1 serving as the reserved bit may be different from the value of the reserved bit xord,1 in Table 1. In Table 1, xord,1 is set to 0, whereas in this situation, the value of xord,1 may be 0 or 1, and xord,1 serves as the reserved bit representing no meaning. In addition, xord,2 may correspond 0 to the secondary uplink carrier, xord,3 may correspond to the secondary downlink carrier, and values of xord,2 and xord,3 may be 0 and may also be 1, where 1 indicates that the secondary carrier is activated, and 0 indicates that the secondary carrier is deactivated. The secondary downlink carrier in the R9 version is equivalent to the 1" secondary downlink carrier in the R10 or R11 version; when a UE of the R10 or R11 version receives the HS-SCCH 25 order of the R9 version, the UE determines the first bit xord,1 among the at least three bits as 0 no matter whether the value of the first bit xord,1 serving as the reserved bit is 1 or 0, explains the order bits according to the HS-SCCH order and Table 2, and updates an activate or deactivation state of the 1" secondary downlink carrier and/or the secondary uplink carrier, which is the same as an expectation of the base station of the R9 version on activation or deactivation the secondary uplink 30 carrier and/or the secondary downlink carrier. For example, when the UE of the R10 or R 11 version receives the HS-SCCH order transmitted by the base station of the R9 version and xord,1, xord,2, xord,3 = "111", the UE determines the value "1" of the first bit xord,1 in the order as "0", that is, the UE determines that xord,1, xord,2, xord,3 = "011", and activates the 1" secondary downlink carrier and the secondary uplink carrier following the illustration in Table 2 rather than activating the 1" secondary 17 downlink carrier and deactivating the secondary uplink carrier, so that an activation or deactivation state of a carrier is the same as an expectation of the base station of the R9 version on the UE. In this embodiment of the present invention, a user equipment receives a High Speed Shared Control Channel HS-SCCH order transmitted by a base station, where the HS-SCCH order carries 5 indication information, and the indication information includes at least three bits; the user equipment determines the first bit among the at least three bits as 0 and updates an activation or deactivation state of the 1" secondary downlink carrier and/or an uplink carrier according to the at least three bits. In this way, the UE is capable of performing a correct activation or deactivation operation when a version of the UE is inconsistent with a version of the base station serving the UE, 0 so that the UE performs correct explanation and processing according to the HS-SCCH order, thereby performing normal uplink and downlink communication.
