A kind of resident target selecting method, transmission method and device

Technical field

The present invention relates to moving communicating field, in particular to a kind of resident target selecting method, biography Transmission method and device.

Background technology

The research of current next generation mobile communication technology is with discussing expansion, following communication system extensively In system velocity, power system capacity, security, reliability, availability, end-to-end delay and battery longevity It can all realize and significantly upgrade in terms of life.Compared with existing network, future communication systems need to meet higher Demand：Network traffics will increase by more than 1,000 times；Will be increased by needing the equipment of connection by 100 times； The speed of more than 100 times than existing network Mean Speed of some application programs requirement, even near zero-lag.

The update of mobile communication technology, will certainly bring many innovation and applications to all trades and professions, mobile Broadband, magnanimity Internet of Things, fire alarm detection and unmanned etc. by as next generation mobile communication system Major use case.But the demand of these use-cases is but not quite similar：For example, being closed for tasks such as fire alarm detections For key Internet of Things, optimal Connection Service need with low latency, it is highly reliable the characteristics of and can cover Certain physical region；Mobile broadband then requires higher data rate, preferably to support 4K/8K Ultra high-definition video, holographic technique, virtual reality etc. are applied.

The network architecture of traditional cellular communication system, from top to bottom with special support and supporting physics Facility resource, this vertical configuration is adapted to the user network of single service type, however, using this vertical Framework, operator is difficult to extend communication network, it is also difficult to which the user's request according to being continually changing is adjusted And meet the demand of new use-case.Therefore, next generation mobile communication network is by logic-based rather than is based on The technology of physical resource, flexibly can carry out resource allocation and reallocation, network will according to user's request It is cut into multiple virtual networks end to end, each virtual network, including equipment in network, connect Enter, transmit and core net, be logically independent, any one virtual network breaks down all without influence To other virtual networks, each virtual network is a network section, and each network section possesses difference Functional characteristics, towards different demands and service, more like a network on demand.Network microtomy Advantage be more than that extensive Connection Service can be provided for all trades and professions, can also for operator reduce net Network Change risk, cuts operating costs, and each network section can be caused to upgrade according to characteristic, gray scale hair Cloth, meanwhile, operator can be faster combined with more flexible with vertical industry, convenient by network energy Power burst is sold, and improves the commercial value of GSM.

Realize that the key enablers of network section depend on SDN (Software Defined Network, software defined network) and NFV (Network Function Virtualization, network work( It can virtualize).The development of NFV technologies so that operator can build different for different business demands Virtual network be possibly realized.Network section is namely based on common physical infrastructure, and network is patrolled Definition and division on volume, form virtual network end to end, and each virtual network possesses different functions Feature, dynamically to meet various demands and business model.NFV first provides a series of instruments, By the software and hardware function of the special equipment in network, including DU (Digital Unit, digital units) and The Network Element Functions such as Core (core net) are transferred to VM (Virtual Machines, fictitious host computer), i.e., Commercial server based on professional standard.Network is after NFV, wireless access mesh portions (edge cloud) One or more VM and core network part (core cloud) one or more VM, pass through SDN skills Art is interconnected, so, and network is used after NFV and SDN, and perpendicular network is divided into being just abstracted Multiple attachable horizontal networks section frameworks, as shown in Figure 1：Network be divided into HD video section 101, Magnanimity Internet of Things section 102 and mission critical Internet of Things are cut into slices 103 3 slice types.According to cutting Piece attribute is different, and DU and Core are respectively placed in edge cloud or core cloud, and side is realized by SDN Edge cloud and the interconnection of core cloud, and the logical independence that holding is each cut into slices.

The function of edge cloud of one typical network section comprising one group of virtualization and core cloud, network is cut Piece is built with strategy according to demand by operator, and the function that a network section includes is also by operator According to demand and strategy decision.Such as, some network sections can also be wrapped in addition to including chain of command function Include special forwarding surface；And some network sections may only include some basic chain of command functions.Specifically Network slice type is as shown in Fig. 2 network supports 4 types to cut into slices altogether：Public section 201 and The slice type of three kinds of customization：First slice type 202, the second slice type the 203, the 3rd section class Type 204；Wherein public section 201 provides basic voice communication service.In the first slice type 202, root Different with business model according to business demand, A1, A2, A3 correspond to three kinds of different network sections respectively should Use example.It is different with business model according to business demand in the second slice type 203, B1, B2, B3 corresponds to three kinds of different network section application examples respectively.In the 3rd slice type 204, according to industry Business demand is different with business model, and it is real that C1, C2, C3 correspond to three kinds of different network section applications respectively Example.

Network section greatly facilitate operator on demand on-premise network and provide customization service, mobile terminal Network section can be flexibly selected to receive carrier service according to self-demand.But the hair of the application A person of good sense has found during technical scheme is realized, the mobile terminal that network is cut into slices to idle condition Carry out bringing problem during cell selection：In existing GSM, cell selection Main Basiss PLMN (Public Land Mobile Network, public land network) is identified, cell RSRP (Reference Signal Receiving Power, reference signal receiving intensity) or cell RSRQ (Reference Signal Receiving Power, Reference Signal Received Quality) and cell attribute, than Whether such as whether the cell is prohibited or reserves, and be classified as in " tracing area is forbidden in roaming " list The parameter such as a part for tracing area, mobile terminal judges whether cell meets certain by above parameter Criterion, so as to select a suitable cell as persistent district, treats to initiate network after the completion of uplink synchronous Connection, so as to set up the full communication link with cell, receives the business service of cell.Idle state is moved Terminal selection cell is carried out after being resident, and mobile terminal needs constantly to perform in the way of above-mentioned selection cell Cell reselection, to be resident, priority is higher or the more preferable cell of channel quality, so as to preferably connect Serviced, or realize that what is loaded between different frequent points or different districts is uniformly distributed.

However, in future mobile communication system, based on migration efficiency and deployment requirements, operator may Can be cut into slices service in the different network of different cell deployments so that mobile terminal is supported in no cell In the case of the prior information of network section, tend not to ensure selection one when performing cell selection operation Support the cell of terminal belonging network section.Once mobile terminal finds that the resident cell of its selection is not propped up Hold belonging to oneself network section when, terminal need disconnect network connection and again initiate cell select or Cell reselection, until choosing the cell of one " correct ".This transparent cell of being cut into slices to network is selected Select and cell reselection operation can bring many wheel cells selections, cause unnecessary space interface signaling expense, when Prolong and power consumption that terminal is larger, had a strong impact on the business experience of user.

In one example of the present embodiment, MT uses this reality in initial cell selection and re-selecting cell The method for applying example, the example comprises the following steps S21~S27：

Step S21：MT carries out cell searching, obtains Time And Frequency synchronization, obtains this cell PCI And the cell such as PLMN selection relevant information.

Alternatively, cell search process may be referred to LTE (Long Term Evolution, Long Term Evolution) System, if the i.e. MT related information of stored PLMN carrier frequencies, while also small comprising some Area's parameter information, for example, being either previously resident or having detected from the measuring control information being previously received Cell in obtain, MT can the prioritizing selection cell that has relevant information scan for；Otherwise, if MT There is no any prior information that MT can be helped to recognize specific system frequency, MT can be according to self-ability All frequency ranges of scanning, and indicate that on each frequency a signal intensity most strong cell is scanned for.

Step S22：MT receives the first signal that BS is sent, and identifies first community and/or first small The network slice type that the neighbor cell in area is supported.

If the first signal is explicitly carried by idle message, MT can decode the first signal and directly obtain The information for the network section that first community is supported, or acquisition first community and its neighbor cell are supported Network section information.If the first signal using implicit carrying mode be contained in PLMN mark or During the exclusive identifier of the cells such as person PCI, it is small that MT can decode corresponding PLMN marks or PCI etc. The exclusive identifier in area, by predetermined mapping ruler, identifies first community, or first community and its neighbour Occupy the information for the network section that cell is supported.

If the first signal is obtained by MT by way of on demand, before step S22, MT According to USIM (the Universal Subscriber Identity Module, Global Subscriber identification locally preserved Card) information or this access purpose or the type of service that will initiate, sent out first to BS Send the first request signal to indicate, carry the identification information of the network to be accessed section, the network section Identification information can include it is any one of following：The mark of network section, network are cut into slices in downstream message Sequence number, a bit map (Bitmap), position in the wherein Bitmap table if " 1 " is set to Show the system message or specialized configuration message for needing to ask corresponding network section.

Step S23：The information that MT cuts into slices according to the PLMN marks and network that report, selects one Individual or multiple suitable potential target cells.

Alternatively, PLMN selection strategies may be referred to LTE system.

Alternatively, section selection strategy, including but not limited to according to terminal unit contractual information, industry type Deng the corresponding network slice type of selection.Such as：Mobile phone belongs to the special equipment of HD video section, Pilotless automobile belongs to the special equipment of mission critical Internet of Things section, therefore corresponding terminal meeting The cell of belonging network slice type is supported in selection.When the network section for thering are multiple cells to be supported simultaneously During with MT belonging network slice types, it can be cut into slices with the higher network of prioritizing selection priority.

Do not have when in the network section represented by information of the MT in the network section according to acquired in the first signal When choosing suitable network section, public section or acquiescence section can be selected to be accessed, About settled in the protocol it can forbid cell selection and access when not finding the section of suitable network, or Person does not find suitable network section and network side is configured without forbidding when public section and acquiescence section Cell is selected and access.

Step S24：MT judges whether potential target cell meets cell selection criterion, i.e., whether MT The primary condition to a cell can be normally resident, is only met in the measurement assessment result of a cell During the cell selection criterion, MT could finally be resident choose Target cell (after resident, the mesh Mark cell is referred to as MT serving cell) in, so as to complete the process of cell selection.

Alternatively, cell selection criterion may be referred to the S criterions of LTE system, or with reference to other movements The applicable cell selection criterion of communication system.

Step S25：Under Idle state, MT carries out cell measurement, monitoring service cell and serving cell Neighbor cell.

Alternatively, cell measurement procedure may be referred to LTE system cell or refer to other mobile communication systems The applicable cell measurement procedure of system.

Step S26：The information that the network that MT is supported according to neighbor cell is cut into slices, the suitable neighbour of selection Cell is occupied as the potential target cell of gravity treatment.

Alternatively, section selection strategy may be referred to step S23.
