In addition, memory 204G may include one or more machine readable medias comprising instruction, instruction is when by herein Machine or component make when executing machine according to embodiment described herein and example, use a variety of communication technologys execution method Movement or the movement of the device or system for concurrent communication.It should be understood that aspects described herein can be by hardware, soft Part, firmware or any combination thereof are realized.When implemented in software, function can be used as one or more instructions or code storage (for example, memory described herein or other storage equipment) on a computer-readable medium, or as computer-readable Jie One or more instructions or code in matter are sent.Computer-readable medium includes computer storage media and communication media The two, communication media include any medium for helping for computer program to be transmitted to another place from a place.Storage Medium or computer readable storage devices can be any usable medium that can be accessed by general or specialized computer.As showing Example rather than limit, this computer-readable medium may include RAM, ROM, EEPROM, CD-ROM or other optical disc storages, disk Storage or other magnetic storage apparatus, or can be used in carry or store expectation information or executable instruction other it is tangible and/ Or non-transient medium.In addition, any connection is referred to as computer-readable medium.For example, if using coaxial cable, light Cable, twisted pair, Digital Subscriber Line (DSL) or wireless technology (for example, infrared ray, radio and microwave) from website, server or Other remote sources send software, then coaxial cable, optical cable, twisted pair, DSL or wireless technology (for example, infrared ray, radio and Microwave) it is included in the definition of medium.
It typically, there are and provide the behave of network service for packet domain.The network service such as UMTS or 3G and predecessor of early stage The CS service and voice service that (2G) is configured in the domain CS for providing different services and packet domain, the especially domain CS are considered having There is higher priority, because customer demand makes an immediate response.Based on the domain for receiving paging, equipment 200 can be arrival Affairs assign certain priority.Now at LTE/5G, most of services are being transferred to packet domain.Currently, UE (for example, 101,102 or equipment 200) paging to packet service can be obtained, without knowing any into one of the paging about MT course Walk information, for example whether someone just calling line, voip call or only from Facebook, other application service or other Some groupings that similar MT service uses.Therefore, for further postponing to have bigger chance, and UE can not distinguish possible hair Rise paging different application grouping and also based on one or more user preference give its different priority.This may for UE It is important, because UE may carry out other tasks prior to resource allocation.
In one example, UE (for example, 101,102 or equipment 200), which may be carrying out, searches the backstage of other PLMN Rope.This is that UE equipment 200 is not attached on the Home PLMN of their own or the PLMN of higher priority at it, but at other May being carried out at regular intervals when the roaming of place for task.According to the list that supplier or subscriber (for example, HSS124) provide, more High priority can be Home PLMN or some other PLMN.Therefore, it reaches and occurs if paging operation is serviced as MT It interrupts, so that starting to be performed with startup operation, then these frequencies interrupted are enough to may cause UE never with reasonable Mode complete backstage search for.This is that one kind is conducive to UE or the network equipment knows that interruption is only packet service (without vertical Make a response to it) still immediately obtain priority arrival audio call (and background scanning should be postponed) one Kind mode.
In addition, equipment 200 can be configured as connection or including multiple subscriber identity/identification module (SIM) card/component, Referred to as double SIM or more SIM devices.Equipment 200, which can use, individually sends and receives component to operate, which can be in SIM Coordinated between the different identity that component is operating.Therefore, the audio call of arrival should be rung as quickly as possible It answers, while in order to be used for for example prior by resource or have from priority list/data set/or user equipment set of preferences Other identity (for example, audio call or SIM component) of higher priority can only relatively ignore the arrival point for application Group.The data that the same scene can be used for other operations or arrive, such as in the search of the backstage PLMN (for example, manual PLMN Search for (this can be continued for an extended period of time)) in the case where, especially in the case where a large amount of different frequency bands from 2G.With In wireless communication the number of frequency bands that utilizes be continuously increased, if incoming page interrupts between the operation run, without The real key service of various groupings and such as voice is distinguished, then the network equipment can explain the manual PLMN search to be taken Business, and going offline or losing for any increment audio call is prevented, especially in the case where interrupting more frequent.
As described above, even if in the case that it is most of these PS data be delay-tolerant and not too important, but losing It stays in network, paging cannot be almost completely neglected, because of the reason of key service as IMS calling may be PS paging.By The delay that the multiple interruption of the search of PLMN caused by paging may cause PLMN search is unpredictable, or in the worst case Even result in the failure of the process.It is moved to preferably in addition, (being searched for via manual PLMN search or HPLMN) under roaming conditions The delay of PLMN may cause the more wandering fees of user.Similarly, the paging channel of two networks is listened to simultaneously simultaneously in UE And have in more SIM scenes of priority for voice service, MT IMS audio call can be interpreted in MT paging message " data " calling indicated, and the MT circuit switching (CS) to other networks that can be initiated simultaneously in user is paged or MO Before CS calling.Therefore, the embodiments herein/aspect can dramatically increase the risk of dropped calls of the SIM using IMS voice service.
In embodiment, 3GPP NW can provide the letter of the further granularity for the service type paged about network Breath.For example, paging cause parameter can indicate one of following values/class/classification: 1) IMS voice/video service;2) IMS SMS takes Business;3) (non-voice/video/SMS is related for other services of IMS;4) any IMS service;5) other PS service (non-IMS is related).It is special Not, the network equipment (for example, eNB or access point) that can only distinguish IMS and non-IMS service can be used 4) and 5), and energy The network for enough distinguishing different types of IMS service (for example, voice/video calling, SMS, message transmission etc.) can be used 3) and It is not 4) explicitly to indicate that paging is for the IMS service different from voice/video and SMS to UE.By obtaining the information, UE can determine the key service pause PLMN search only for the voice/video service such as to arrive.
In other respects, service type (for example, value or class 1-5 above) is depended on, UE 101,102 or equipment 200 can To remember the paging not responded to there are it, and later PLMN search completed and UE decision stay on current PLMN When access network.For example, if the reason of paging is that mobile station called IMS SMS, MME can notify HSS (for example, 124) UE is reachable again, and HSS124 can initiate signaling procedure, once the process will be so that for example resource be more or for another One operation/application/or classification are less urgent, then SMS are transmitted to UE.For this purpose, for example, if service type in paging message It indicates " IMS SMS service ", then UE 101,102 or 200 can initiate periodic Tracking Area update (TAU) process.
