The

development

of

mobile

Internet

and

Internet

of

Things

sharply

increases

needs

of

bandwidth

and

rate

of

mobile

network



In

a

typical

urban

macro/micro

scenario

with

lots

of

users,

the

network

capacity

is

a

bottleneck

of

the

user

experience

AFN

(Intra

Frequency

Networking)

is

that

the

service

and

neighbor

cells

work

in

the

same

spectrum,

namely

sharing

same

sub
-
carrier

resources



RFN

(Inter

Frequency

Networking)

means

the

service

cell

works

in

the

different

spectrum

different

from

neighbor

cells

This

article

thus

briefly

reviews

the

features

of

M
2
M

services

in

the

third

generation

(

long

term

evolution

and

its

advancement

(LTE

networks



With

M

communications,

devices

“talk”

to

each

other

through

wired

or

wireless

connections

and

data

without

For

mobile

service

operators,

services

through

M
2
M

communications

have

promising

and

strategic

values
.

For

instance,

a

large

number

of

M
2
M

services

are

non
-
real

time

and

typically

consume

little

bandwidth,

with

minimal

impact

on

the

capacity

of

radio

access

networks

(RANs
)



The

scope

of

this

article

is

hence

to

examine

how

H
2
H

users

and

MTC

devices

can

share

available

radio

resources

efficiently

so

as

to

mitigate

co
-
channel

interference

and

thus

enhance

network

efficiency

,

there

exist

between

.

In

certain

time

instants,

occur

with

the

Aid

of

an

MTC

Gateway



In

order

to

mitigate

or

eliminate

negative

effects

of

M
2
M

communications

on

H
2
H

communications,

an

MTC

gateway

can

be

deployed

in

cellular

networks,

where

all

MTCDs

are

connected

to

the

eNB

indirectly

through

the

relaying

of

the

MTCG

An

locally

with

entities,

which

provide

the

with

raw

for

processing

and

communicating

to

the

and/or

Machine

machine

communication

will

be

one

of

the

focuses

in

LTE
-
A,

as

the

demand

of

M
2
M

is

increasing

so

greatly

recent

years

and

might

eventually

exceeds

the

human
-
to
-
human

communication
.




Like

the

first

generation

M
2
M,

a

major

part

of

M
2
M

uses

SMS

as

the

communication

method,

and

the

machines

only

send

small

amount

of

data

once

a

time
.

It

is

not

a

problem

when

there

are

few

machine

devices

in

the

network

In

current

specification,

only

very

limited

categories

of

handset

capabilities

are

supported,

and

even

the

lowest

category

can

provide

what’s

more

than

the

metering

needs



The

LTE
-
A

physical

layer

chain

contains

the

following

six

function

blocks,

including

physical

channels

supported,

coding

schemes,

modulation

schemes,

maximum

transmission

power,

bandwidth

configuration,

RF

configuration

Since

these

machines

are

deployed

by

large

company,

it

is

easy

to

make

the

conformance

test

of

the

new

devices,

so

network

operator

does

not

need

to

worry

the

impact

on

the

current

With

the

is

expected

to

saturate

in

the

near

(RATs),

future

costs

can

be

To

in

one

of

the

is

to

resolve

a

of
