It should also be noted that similar label and letter below figure represent similar terms, therefore, once a certain Xiang Yi accompanying drawing is defined, then it need not be further discussed in accompanying drawing subsequently.
Fig. 1 is the structural representation illustrating terminal according to some embodiments of the invention.As it is shown in figure 1, terminal 100 includes: detection module 101 and resident module 102.Wherein,
Detection module 101 is for when judging to combine attachment acceptance but CSFB can not use, and detection service parameter is arranged.
Resident module 102 is for when judging that service parameter is set to centered by voice service (i.e. Voicecentric), current LTE network is kept attachment (namely not carrying out attachment removal), and reside in circuit commutative field (such as, the circuit commutative field of 2G or 3G) or this LTE network.
In this embodiment, detection module is when judging to combine attachment acceptance but CSFB can not use, and detection service parameter is arranged；When detection module judges that service parameter is set to Voicecentric, current LTE network is kept attachment by resident module, and resides in circuit commutative field or this LTE network.
In an embodiment of the present invention, circuit commutative field carries out voice service for terminal；LTE network carries out data service for terminal；Wherein, described circuit commutative field is the circuit commutative field of 2G or 3G.
Such as, the process combining attachment may include that terminal (such as, LTE terminal) carries, in the associating Attach Request message sent to MME (MobilityManagementEntity, mobile management entity), the instruction supporting CSFB function；MME receive user combine attachment request after, when carrying out EPS attachment, VLR (the VisitorLocationRegister in CS territory (circuit commutative field) can be derived, VLR Visitor Location Register) information, and it is more newly requested to this VLR launch position, after VLR receives position updating request, can mark the user as and have be carried out EPS attachment, and preserve the IP address of the MME of user, so, VLR creates SGs (SignallingGateways, the SGW) association between VLR and the MME of user.Subsequently, MSCServer (MobileSwitchingCenterServer, Mobile Switching Center Server)/VLR carries out CS territory location updating and the TMSI (InternationalMobileSubscriberIdentity of user, international mobile subscriber identity) and LAI (LocationAreaIdentity, Location Area Identification) send to MME, set up SGs with MME and associate.The attachment request of the information such as TMSI and LAI comprising VLR and distributing to user is accepted message and sends to terminal by MME, then combining of user adheres to successfully.Combining after adhering to successfully, the user enabling CSFB function in the lte networks can processing circuit domain service.
In this embodiment, first terminal is attached to LTE network, then LTE realizes circuit domain dropping to 2G/3G network by associating attachment, and such terminal can realize circuit domain business (such as voice service (i.e. voice call) etc.) by the circuit domain of 2G/3G (such as GSM or WCDMA etc.).
nullIn another embodiment，In the process combining attachment，Although terminal can be attached to LTE network，But circuit domain dropping might not be successful，If circuit domain dropping can not be successful，Then combine and adhere to unsuccessfully，Although or combine attachment can be successful，But some agreement prescribed terminal can not use CSFB，Such as some agreement prescribed terminal can receive combines attachment acceptance and carries the notification message that " EPSonly " (only the grouping system of evolution) indicates、Combine attachment success and carry notification message that " SMS (ShortMessageService) only " (can only use SMS (Short Message Service)) indicate or combine attachment success and carry the notification message that " CSFBNotPreferred " (circuit domain dropping non-preferential) indicates，These instructions all will cause that terminal can not use CSFB.
In an embodiment of the present invention, terminal also includes: receiver module, for receiving the notification message of associating attachment；Wherein, notification message includes: combine attachment refusal, combine attachment accept and carry " EPSonly " indicate, combine attachment success and carry " SMSonly " indicate, combine attachment success and carry " CSFBNotPreferred " indicate or combine adhere to successfully and without " SMSonly " instruction and nothing " CSFBNotPreferred " indicate.
In another embodiment, when receiver module receive combine attachment accept and carry notification message that " EPSonly " indicate, combine attachment success and carry notification message that " SMSonly " indicate or combine attachment success and carry notification message that " CSFBNotPreferred " indicates time, then detection module determines that combining attachment accepts but CSFB can not use.
In another embodiment, terminal (such as LTE terminal) is when being set to CSVoiceonly, carry out combining attachment (combinedEPS/IMSIattach) process, if combine attachment accept but CSFB can not use (such as, the receiver module of terminal receives combines attachment acceptance and carries the notification message that " EPSonly " indicates, combine attachment success and carry notification message that " SMSonly " indicate or combine attachment success and carry the notification message that " CSFBNotPreferred " indicates) time, the detection module detection service parameter of terminal is arranged；When detection module detects that service parameter is set to Voicecentric, current LTE network can be kept attachment (namely the LTE network currently adhered to not being carried out attachment removal) by resident module, and resides in circuit commutative field (circuit commutative field of such as 2G or 3G) or this LTE network.So can so that terminal is not when supporting 2G/3G, resident on an LTE network, it is achieved the business such as LTE online；Or terminal is when supporting 2G/3G, reside at 2G/3G, and due to terminal not to LTE network attachment removal, therefore can also reside in LTE network, so that terminal can utilize LTE network to realize data service (such as online), and circuit domain business (such as voice service) can be realized by the CS territory of 2G/3G.
In another embodiment, resident module, when judging that service parameter is set to centered by data service (i.e. Datacentric), resides in current LTE network.Such as, terminal receive combine attachment accept and carry notification message that " EPSonly " indicate, combine attachment success and carry notification message that " SMSonly " indicate or combine attachment success and carry notification message that " CSFBNotPreferred " indicates time, the detection module detection service parameter of terminal is arranged, when detection module detects that service parameter is set to Datacentric, resident module resides in current LTE network, thus realizing terminal can use LTE network when carrying out data service.
