S22：The first terminal initiates the access to second terminal, and the target ip address of uplink message is described second whole
The IP address at end.
S23：Mobile core network judges the target ip address to be in the first terminal according to the uplink message
During the IP address of identical services network, the uplink message Jing radio honeycomb access networks are routed into the second terminal.
Mobile core network checks uplink message, if finding, the target ip address that first terminal is accessed is to be in first terminal
The IP address of other terminals of identical services network, rather than the address of external business network, then can directly by uplink message
Jing radio honeycomb access networks are routed to second terminal.
Second terminal receives the uplink message of first terminal transmission, that is, complete terminal and directly access via radio honeycomb
Net and mobile core network access other terminals, realize the direction communication of terminal point-to-point, without the need for connecting business network, can make
Terminal breaks away from the restriction of business network connection.
Preferably, the method for terminal mutual of the present invention is further included：Terminal is entered according to the IP address of terminal
Row packet, the terminal of identical services network is divided into one group.Then, the judgement of target ip address is further included in step S23：Move
Dynamic core net obtains the target ip address of the uplink message, is located in the first terminal according to the target ip address and is grouped
In matched, if the match is successful, judge the target ip address as with the first terminal in identical services network
IP address.So as to optimize mobile core network to accessing whether terminal is in the judgement of identical services network with target terminal.
The present invention can also set first terminal and access other terminals or the routing policy of other set of terminal, realize end point
To point or point-to-multipoint direction communication.
Preferably, in the method for terminal mutual of the present invention, step S23 further includes the place to uplink message
Reason, specially：1) according to the contextual information of IP address index search to the second terminal；32) uplink message is removed
The tunnel header of middle message encapsulation, and using the tunnel information in the contextual information of the second terminal to the uplink message
Re-start encapsulation；3) the uplink message Jing radio honeycomb access networks after encapsulation are routed into the second terminal.So as to optimize
Process of the network side to message.
The method of terminal mutual of the present invention, can make terminal break away from the restriction of business network connection so that terminal
Between mutually access can be directly realized by inside mobile core network, without the need for connecting business network, extend networking application scene,
Point-to-point and point-to-multipoint communication pattern can be directly realized by.
Next the embodiment that accompanying drawing provides the system of terminal mutual of the present invention is combined.
With reference to Fig. 3-4, wherein, Fig. 3 is the Organization Chart of the embodiment of system one of terminal mutual of the present invention, and Fig. 4 is

Two terminals 32.
The processing module 41 of mobile core network 34 checks uplink message, if finding the target ip address that first terminal 31 is accessed
It is the IP address with first terminal 31 in other terminals of identical services network, rather than the address of external business network, then
Directly uplink message Jing radio honeycombs access network 33 can be routed into second terminal 32.Second terminal 32 receives first terminal
31 uplink messages for sending, that is, complete terminal and directly access other ends via radio honeycomb access network and mobile core network
End, realizes the direction communication of terminal point-to-point, without the need for connecting business network, terminal can be made to break away from the limit of business network connection
System.
In order to be compared with existing terminal mutual mode shown in Fig. 1, business network 35 is still illustrated in Fig. 3, but
Not interact between terminal and business network 35 in terminal mutual, i.e., can be direct inside mobile core network between terminal
Realize accessing mutually, without the need for connecting business network, extend networking application scene, point-to-point and point-to-multipoint can be directly realized by
Communication pattern.
Preferably, mobile core network of the present invention 34 further includes grouping module 42, for according to the IP of terminal
Address is grouped to terminal, and the terminal of identical services network is divided into one group.Then, the processing module 41 is to target ip address
Judging further can be as：Obtain the target ip address of the uplink message and call the grouping module 42, according to the mesh
Mark IP address matched in a packet in the first terminal 31, if the match is successful, judge the target ip address as
With IP address of the first terminal 31 in identical services network.So as to optimize 41 pairs of visits of processing module of mobile core network 34
Ask whether terminal is in the judgement of identical services network with target terminal.
The present invention can also set first terminal and access other terminals or the routing policy of other set of terminal, realize end point
To point or point-to-multipoint direction communication.
Preferably, processing module of the present invention 41 is further included：Searching unit 411, Reseal unit 412 with
And routing unit 413.The searching unit 411, for according to the context of IP address index search to the second terminal 32
Information.It is described to Reseal unit 412, for removing the uplink message in message encapsulation tunnel header, and using described
Tunnel information in the contextual information of the second terminal 32 obtained in searching unit is re-started to the uplink message
Encapsulation.The routing unit 413, for Resealing the uplink message Jing radio honeycombs access network 33 after unit is encapsulated by described
It is routed to the second terminal 32.So as to optimize process of the network side to message.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
