Abstract

A service implementation method for Internet Protocol (IP) multimedia subsystem network is provided. Once receiving a request with a User Equipment (UE) number for providing a roaming number from a home network for the UE in roaming state, the Visitor Subscriber Server (VSS) returns a roaming number corresponding to the UE number and directing to the Location Application Server(LAS) to the home network for the UE; once receiving an initial address message carrying the roaming number and initiated by a caller, the Media Gateway Control Function (MGCF) entity transmits a session invite message to the LAS via the Service Call Session Control Function (S-CSCF) entity, wherein the roaming number is carried in the message; the LAS takes the UE number as a callee number to instead the roaming number in the session invite message, and sends the session invite message to the S-CSCF entity; based on the callee event triggering standard for the Initial Filter Criteria (iFC), the S-CSCF entity transmits the session invite message to the Telephony Application Server (TAS) to implement the call control; based on the local storied user data of the UE, the TAS implements the call control; after the completion of the call control, the TAS transmits the session invite message to the UE via the Proxy Call Session Control Function (P-CSCF) entity.

Description

Wood field

This is related to the field of communication, especially related to e e Pooco, P 5 multi-media system and methods.

Background

To maintain the competitiveness of third-generation partners (dGe e a o s p oec, 3GPP) in the field of communications, 3GPP is currently working on packet switching 10 ( acke Sw ched Co e, P Co ) and global communications

(ve sa ob eTeecomm ca o SysemRadoAccess ewok,

The purpose of TRA is to make P Co e (PC) provide higher speed, more, support TRA (Evoved TRA - TR, global enhanced rate global G 15 GP (G E G adoaccess ewok, G R TRA

(eess oca ea ewok, W A and other non--3GPP management systems. (voved acke Sysem, P)

And each item is important, so 2 is high in P and each is very important. At present, everyone compares to P's multi-media () and each.

104 Each call control function (Se V gCa Sesso Co o F c o , -C C ) is available for user-provided, call control, etc.

105 users each ( ), save the user's, call or provide support.

As shown in Figure 1, the user receives the P-C CF, and the user is successful, and the user and each message to the message, by -C CF

Message specific user, control is completed.

In the case of local deployment, if the user arrives and the same is not deployed, it is possible to send messages (examples, messages, messages) to

And each failure, the same message (example, message) may also be. Content

The wood to be solved by the firm is to overcome the shortcomings of existing wood and provide various methods and systems for God's local call control.

In order to solve the problem, the present invention provides a method for the P-community system, and the method includes the proxy call control function of the local P-multi-media system of the users who occupy the user, and the PC CF kimono call control function-C CF Local users are successful,

The received offer will be returned to the local location of each A

Among them, TA and A force local or local local sheep.

This p, before the step of receiving the provided, and before the step of returning, the method includes the allocation to the A,

A receives the steps of assigning, allocating, and saving, returning the message received by V at A, and before the step of replacing, the method includes the location of the saved A.

In addition, the method includes, prior to the step of providing, and before the step of returning, the method includes the assignment, the saving of the received message at A, and before the step of replacing , the method includes the A direction

The message, the message received in the message, will be returned to A In this case, the FC includes a step of generating the FC-C CF by the generating method, and the steps include

In the case where the -C CF is received, the message is sent to the -C CF, and the message contains C. In addition, the event is included in the FC.

The method includes the steps of the TA user, the steps include: the message received by the C-C CF, and the event in the FC to the user of the TA,

Receiving the third, the TA sends a user message, the user in the message

Receiving the user message, returning the locally stored user to the TA

Thus, the method includes the steps of SS storing the user described, including

In the middle, the -C CF is received, and the R or R position is updated to retrieve the user.

Receiving a location update, the R or SS will be the user

In addition, in the near-term, the -C CF is received, the R or R location is updated, so that the user stores the R or the returned user.

This is provided by P (Multimedia) ( ) for each of the local users ( A ) , the following users ( □ ) , users ( ) saved users

15 It should be noted that consisting of TA and A elements, due to

The special TA 5a is a local (local, local) local method of the J user (i.e., the method of receiving the 0 message local -C CF in step 402). In this process, by local

In the existing wood, P-C CF is receiving the message, the message with the name of the message -C CF is in the middle, P-C CF is receiving the message, strategy, directly put

5 Message From the local -C CF, the local -C CF breaks the local line.

As shown in Figure 5a, the method has the following steps:

5a (ie step 401), a message to the local PC CF, Neutral user identity

5a 2, received the message, P-C CF user identity and policy, whether local (ie whether the message will be received locally -C CF), Hugh and strategy can be

In the existing wood, PC CF is receiving the message, and needs to send the message to the user's -C CF address, and the address of the core-C CF will be in the middle. The strategy will cost the local-C CF. Hugh address.

As shown in 5b, the method is closed.

In this process, P-C CF is the full name, and P-C CF is the full name. The process shown in 5c, before step 401, the rest includes the following steps

5c, P-GW P-C CF full name message

5c 5 -C CF The full name, if you want to use the local and each, then the PC CF will be the full name (that is, the character of the "Q" character in the PC CF full name). This message will be included in the message in step 401. Note: In step 402, the name in the local PC CF Hour message will be local-C CF. 5d Received message User's method flow This process is in step 4 of 407, the method of receiving the message user, as shown in 5d, the method includes the following steps

701. The local P-C CF message has been successfully sent, the message is in the message, and the message is

702. The local PC CF idles the routing information of the mercury to the local-C CF Hugh message 703, receives the message, and the local-C CF suspends the event in the third call control (ie, the local-C CF does not call control, and By call control), by message

The call in the TA in the 704 calls the call control (eg, whether the call is allowed), the call control is completed

The message is sent to the local -C CF, local -C CF, and the message is sent to GCF.

Connect the call, where the event in the local -C CF is in the FC. The message received by the Brigadier General A, A completes the call control and then the message local -C CF is taken off.

15 It should be noted that it consists of TA and A elements, because the special TA 8 in 7 uses the system flow of this method, 20 receives the provision of R, and the local configuration allocation refers to A, or to A, by A configuration allocation V will use RGC, GC uses the completed process pointing to A. In this, the functions of A and TA are closed, and they can be combined. The method shown in 8 includes the following step 25 801 T call has been sent to the local system ("), P T to the user's G C address message (A), in the message

Therefore, V can also be assigned to A, save and 10 . In the case of God, steps 804 and 805 may not be performed.

806 807 V e points to A's return R, T R will return to G SC

The 808 GC sends a message to the GCF (A) to route the call to the GCF, and the message is carried in and the message 15 809 810 GCF will be received by A (ie, -C CF A message) 811 812 A. If the decision message contains a non-this A assignment, then the message is sent to

The above message contains V found before 0 saved, will return A

Therefore, A receives the message, and if it is determined by the present A in the message, it is found in the case of God saved, and step 811 812 is not required.
