Embodiment Construction

[0054] Embodiments herein relate to synchronization of MCCH update signaling for distributed MCEs.

[0055] Figure 4 A communication network 400 is shown in which embodiments herein may be implemented. The communication network 400 is suitable for a radio access technology such as LTE.

[0056] The wireless communication network 400 comprises a first eNB 401a serving a first cell 403a and is an entity capable of communicating over a radio bearer with user equipment 405 present in the first cell 403a. User equipment 405 supports MBMS and / or eMBMS. The first eNB 401a includes an MCE (not shown).

[0057] The wireless communication network 400 includes a second eNB 401b serving a second cell 403b, and is a unit capable of communicating over a radio bearer with user equipment 405 present in the second cell 403b. The second eNB 401b includes an MCE (not shown).

[0058] When the user equipment 405 eg moves from the first cell 403a to the second cell 403b, the user equipment 40...

Abstract

Embodiments herein relate to a method for processing MBSFN area configuration information in an eNB (401). The eNB (401) receives (501, 801) a MBMS session start request from the MME (410). Based on the received request, the eNB (401) calculates the first time to start the MBMS session. The first time is the first MCCH update time. The eNB periodically sends (504, 804) the configuration information to the user equipment (405) starting from a first time. When the MBMS session is the last MBMS session, the eNB (401) stops (507, 807) sending configuration information to the user equipment (405). When the MBMS session is not the last MBMS session, the eNB (401) sends (508, 808) updated configuration information to the user equipment (405). The updated configuration information is updated MBSFN area configuration information.

Description

technical field [0001] Embodiments disclosed herein relate generally to evolved Node Bs (eNBs) and methods in eNBs. More specifically, embodiments herein relate to processing configuration information. Background technique [0002] In a typical cellular network (also referred to as a wireless communication system), user equipment (UE) communicates with one or more core networks (CN) via a radio access network (RAN). [0003] User equipment is a device that a subscriber can use to access services provided by the operator's network and services outside the operator's network to which the operator's radio access network and core network provide access, such as access to the Internet . The user equipment may be mobile or fixed any equipment capable of communicating on a wireless channel in a communication network, such as but not limited to mobile phones, smart phones, sensors, meters, vehicles, household appliances, medical equipment, multimedia players , cameras, or any con...
