Refer to that the terminal residing in LTE network, due to the needs of speech business, is left LTE network and returned to 2/3G
Network initiates the technology of CS territory audio call.Multimode list treats that CSFB terminal can be operated in LTE pattern,
2/3G pattern can also be operated in, but synchronization can only operate under a kind of pattern.
CSFB call flow can be divided into three parts:
Part I, the redirection process issued by network is fallen after rise to 2/3G network；
Part II, 2/3G network signal is resident and read system message in search；
Part III, carries out audio call in 2/3G network.
Wherein, the process that terminal searching 2/3G network signal is resident specially terminal searching network issues and resets
The all 2G frequencies specified in order, selection RSSI (Received Signal Strength Indication,
Received signal strength indicator) the strongest GSM (Global System for Mobile Communication,
Global system for mobile communications) community is resident, if the GSM frequency that network configures in redirecting order is not
Meeting condition, or be configured without GSM frequency, terminal needs to search for GSM full frequency band, selects RSSI
The strongest GSM frequency.
Due to PLMN (Public Land Mobile between the operator of two country /region of border area
Network, public land mobile network) different, it is impossible to mutually carry out cell reselection and switching.Even if eventually
It is very strong that end can measure bipartite network RSSI signal, passes through web search and net after also can only waiting until off-grid again
Network selects to register, and causes the telex network break period longer, and there is automatic network selection to non-Partner
The probability problem of network.
In order to solve the problems referred to above, prior art proposes EPLMN (Equivalent PLMN, equity
PLMN), the effect of EPLMN is when roaming across PLMN, and terminal prioritizing selection signing registered network pushes away

(Routing Area Update), tracing section updating (Tracking Area Update), GPRS (General
Packet Radio Service, GPRS) attachment (GPRS Attach), LTE adhere to (LTE
Attach), during, network sends EPLMN list to terminal, terminal can by this EPLMN list and
The PLMN sending this list is collectively stored in " Equivalent PLMNs " table of terminal.
If network is configured with EPLMN in border area, it is specially the operator in this country/area by nearby nations
The PLMN mark of/area carrier network is configured to the EPLMN of this country/LAN, in this region
Terminal can carry out cell reselection to nearby nations/LAN at Idle state from this country/LAN, is connecting
State switches over or is redirected to nearby nations/LAN from this country/LAN, it is not necessary to wait until off-grid
After select to register by web search and network again, the bigger time delay saving Roaming Registration.
But, if network configuration EPLMN, when terminal home/LTE network in area under initiate
During CSFB calling, if network GSM frequency of configuration in redirecting order is unsatisfactory for condition, or
Being configured without GSM frequency, terminal needs to search for GSM full frequency band, selects GSM the strongest for RSSI
Frequency, owing to border exists the overlapping covering of two country /region networks, terminal likely can select neighbouring state
The GSM cell of family/LAN is resident, and the EPLMN due to network configuration, terminal is to select
The GSM cell in nearby nations/area is resident and completes CSFB calling.When terminal is hung up, autonomous
When returning to LTE network, then it is excellent owing to current terminal independently returns LTE network industry implementation
First select the last resident LTE frequency point, then terminal may will return the LTE net in this country/area
Network, causes table tennis network selection problem terminal occur between multinational operator network, and this problem not only have impact on
Consumer's Experience, also causes being difficult to CSFB call charging and clearing between multinational operator.
